Definitions
- the method, object of the present invention aims to selectively clean or improve the epidermal mass of various objects, while respecting their visual appearance and their surface condition, whether the epidermis is made of plastic, rubber, leather, or other material having a surface provided with pores and / or expandable, or a surface capable of being provided with microscopic cavities and / or asperities.
- the direct surface treatment methods generally use chemical adhesion phenomena exerted either on the object by erosion and / or chemical fusion, or on the filler material by overactivated polymerization (inks and varnishes dried by radiation UV or IR), or adding glue (French Patent No. 2252743 of 12/26/1973).
- the characteristic of indirect surface treatment methods is not to directly treat the surface, but rather to treat the epidermal mass underlying the surface of the treated objects. They subject the aforementioned objects to the swelling action of solvents or mixtures of powerful solvents such as: tetrahydrofuran, cyclohexanone, dimethylformiamide, carbon sulfide, chloroform, butyl alcohol, trichlorotrifluoroethane (freon 113), methylene chloride, etc.
- solvents or mixtures of powerful solvents such as: tetrahydrofuran, cyclohexanone, dimethylformiamide, carbon sulfide, chloroform, butyl alcohol, trichlorotrifluoroethane (freon 113), methylene chloride, etc.
- solvents or mixtures of powerful solvents such as: tetrahydrofuran, cyclohexanone, dimethylformiamide, carbon sulfide, chloroform, butyl
- the multiple physical displacements of the epidermis of the object caused by a chemical phenomenon generate a mechanical phenomenon of adhesion allowing an insertion into the epidermal mass of liquid and soluble additives, by immersion except oxygen and ambient humidity (French Patent N o 1,312,260 of 13.01.62), (European Patent N ° 0.134.523 of 23.07.84 or US Patent N ° 520.241 of 04.08.83), or an insertion into the epidermal mass of semi-liquid and not completely soluble additives (vinyl inks), without immersion, by mechanical action of a friction with a bristle brush (French Patent Application N ° 86.16621 dated 27.11.86).
- the new indirect surface treatment method, object of the present invention aims to correct the drawbacks and inadequacies of the existing direct and indirect methods.
- the invention no longer aims only to add and / or modify filler materials, but to subtract therefrom. It uses the effect of dilation of the epidermis of the object to unclog unwanted additives, wet them and extract them by using the capillary effect of a sponge or spongy material pressed against the surface of the object. It thus becomes the first method of cleaning the epidermis of an object.
- the invention allows the insertion of selected additives at the same time as the extraction of undesirable additives.
- the dilation effect is long enough for the two operations to take place before the retraction effect begins, giving the impression of a single selective action and not of two simultaneous actions.
- the invention thus becomes the first selective surface regenerating descaler.
- the invention corrects the vulnerability of the adhesion of liquid, semi-liquid, and solid additives, by adding to them preferably adhesive materials, capable of filling the microscopic cavities and asperities in the fluid state, and hardening by conforming to the form. of these cavities and asperities, so as to no longer be vulnerable to an unwanted accidental expulsion.
- Liquid additives can for the first time benefit from the mechanical retention effects caused by the retraction of the epidermis of the treated object and increase their efficiency by approaching the surface while being better protected since they are more difficult to conceal by the body. undesirable whose privileged reception area has been removed.
- Semi-liquid and solid additives can for the first time be selected in the smallest particle sizes and thus simultaneously improve their penetration and retention.
- the invention aims to obtain a particular resistance to hydrocarbons, water, and detergents, for certain applications. A distinction is therefore made between the solubility of the additives before hardening or after hardening, the maximum fluidity being sought in the first phase, and maximum insolubility in the last phase.
- the invention gives access, without limitation and in addition to the cleaning treatment, to very numerous surface treatments, rapid, simple or combined, perfectly localized, applicable in situ, without infrastructure and without disassembly, aiming to remove, modify or add stabilizers to UV, heat, static electricity; flame retardants, smoke retardants, toxic gases; foaming agents, antioxidants, fluorescers, reflectors, absorbents, electricity conductors, insulators, abrasion resistant, abrasives, lubricants; dyes, pigments, dyes, etc ...
- the invention allows, thanks to its ability to fully use the retraction effect, to modulate the aggressiveness of phase 1 with respect to the epidermis to be treated (non-restrictive example of a variable attack of the epidermis according to the nature and concentration of the solvents), and to make the new process accessible to faster, less polluting and more flexible methods of application.
- the invention by its flexibility of use and its ability to make full use of the retraction effect, can use the modes of application by immersion and by friction with the bristle brush, but also by spraying (gun, pump, spray can , spray, etc ...), by friction with a sponge, glove, vegetable fiber brush, roller, etc ...
- Phase 1 can be obtained: on very high pressure from an appropriate fluid, liquid, semi-liquid, or powdery mixture; on very high pressure of a gas preceding the setting of the hardener mixture; on the action of solvents and mixtures of solvents such as, with non-restrictive title: tetrahydrofuran, cyclohexanone, dimethylformiamide, carbon sulfide, chloroform, butyl alcohol, methylene chloride, trichlorotrifluoroethane (freon 113 ), etc ...
- Phase 2 can be obtained: on any capillary action and particularly capillary action of a sponge pressed against the surface of the object to be treated and the entrances or access routes to the abovementioned cavities and asperities, the sponge preferably being at fine, unclosed structure, compatible with the chemicals and the method of application selected on very high pressure of a fluid hardener mixture, in liquid, semi-liquid or powder form; on application of a gas overpressure or underpressure, or even of the vacuum preceding the setting of the hardener mixture; on evaporation of volatile residues remaining after hardening of the mixture in contact with occluded gases or ambient humid air.
- Phase 3 can be obtained: on friction with a sponge or coating glove; on friction with a roller or brush, vegetable or other; on spray, spray, aerosol, pump, etc ...; pressure, lance, press, etc ...; even on soaking, when the entire epidermis must be treated.
- Phase 4 can be obtained: on reaction to oxygen and to humidity of the agents in the hardening mixture; upon reaction with a modified, acidic, basic, or neutral gas atmosphere; on reaction with natural or artificial light; on reaction with radiation, ultraviolet or other; on reaction to heat or cold of the agents in the hardening mixture; on the disappearance one of the mixing agents, by evaporation, chemical transformation, drying, selective racking, etc ...; on release of a blocked, inhibited reagent or catalyst; on any other means allowing the required hardening to be obtained.
- Phase 5 can be obtained: on wiping with a sponge, glove, rag, brush, roller, drips or burrs that may have accidentally occurred during application.
- the hardening mixture consists of at least two agents: the additive to be inserted which is very fluid to facilitate insertion and the adhesive or chemical agent capable of agglomerating the additive after it has penetrated into the cavities and / or microscopic roughness.
- the agglomerate between adhesive and liquid, semi-liquid or solid additive reconstitutes particles in situ which are remarkable for their size greater than that of the access routes to the abovementioned cavities and asperities, and for their shape perfectly matching those of said cavities and asperities. .
- the hardener mixtures despite strong differences which may exist in their formulations, their storage conditions, their packaging and their instructions for use, all have an evolving solubility which does not create unfavorable conditions for the smooth running of phases 1, 2, 3, 4, 5, and even makes it possible to modulate the aggressiveness of phase 1 with respect to the epidermis to be treated, but brings, after the total hardening of phase 4, insolubility to most of the predictable chemical aggressions of which wanted to preserve the objects treated, and sometimes even a insolubility to some of the solvents which kept the hardening mixtures in the fluid state during phases 1, 2, and 3.
- the following surface regenerative selective descaler is applied to the sponge for the maintenance of the interior of cars: - Aqueous acrylic dispersion 46% - Methyl alcohol 22% - Butethyl acetate 6% - Dichloromethane 6% - H2 O 17% - Methyl-Ethyl-Cetone 3%
- the following repigmenter is applied to the aerosol for the regeneration of vehicle bumpers: - Semi-liquid premix of insoluble pigments in a cellulosic substrate 13.50% - Butethyl acetate 20.00% - Methyl-Ethyl-Cetone 15.00% - Cyclohexanone 27.50% - Diluted cellulosic glue 16.00% - Dichloromethane 8.00%
- the process and related products are intended for professional and private users who have to clean, maintain, or remodele various objects made of plastic, leather, rubber, or other materials.

Le procédé, objet de la présente invention, vise à nettoyer ou améliorer sélectivement la masse épidermique d'objets divers, en respectant leur aspect visuel et leur état de surface, que l'épiderme soit en plastique, caoutchouc, cuir, ou autre matériau ayant une surface munie de pores et/ou dilatable, ou une surface apte à être munie de cavités et/ou aspérités microscopiques.The method, object of the present invention, aims to selectively clean or improve the epidermal mass of various objects, while respecting their visual appearance and their surface condition, whether the epidermis is made of plastic, rubber, leather, or other material having a surface provided with pores and / or expandable, or a surface capable of being provided with microscopic cavities and / or asperities.
Il est connu que certains matériaux, plastiques ou non, refusant de se solidariser avec des matériaux d'apport après façonnage, plusieurs procédés de traitement de surface ont cherché à vaincre ce problème d'adhérence.It is known that certain materials, plastic or not, refusing to join with filler materials after shaping, several surface treatment methods have sought to overcome this problem of adhesion.
Les procédés de traitement direct de surface ont pour caractéristique de traiter non pas l'épiderme sous-jacent à la surface, mais la surface des objets. Ces procédés imposent la superposition de matériaux de nature et épaisseur différentes. Bien que très connus et encore très utilisés de nos jours à cause de leur souplesse d'emploi n'exigeant pas le démontage préalable des objets à traiter, ils présentent de nombreux inconvénients:
- le premier est de modifier directement et de façon plus ou moins sensible l'état de surface des objets traités. L'aspect initial de l'objet n'est jamais respecté par les peintures opaques et généralement assez épaisses, mais il ne l'est pas davantage par les vernis et encres translucides. La transparence donne l'illusion trompeuse de préserver l'intégrité de la surface de l'objet au moment où la surépaisseur provoquée par le matériau d'apport en estompe les motifs gravés et reliefs de surface.
- le second est l'impossibilité d'échapper à des contraintes élevées de propreté et d'environnement avant, pendant, et après l'enduction ou encrage
- le troisième est l'impossibilité d'échapper aux compromis jamais pleinement satisfaisants de compatibilité entre matériau(x) d'apport et matériau de l'objet à traiter. Par suite de résistances initiales différentes à la température, aux produits chimiques, à l'abrasion, aux chocs, aux U.V., les matériaux évoluent de façon souvent imprévisible et contrecarrent les précautions prises pour supprimer les risques de délaminage consécutifs aux dilatations différentielles, et les autres risques de jaunissement, de corrosion, de faïençage, de rayures, etc...
- the first is to directly and more or less significantly modify the surface condition of the treated objects. The initial appearance of the object is never respected by opaque and generally quite thick paints, but neither is it respected by varnishes and translucent inks. The transparency gives the deceptive illusion of preserving the integrity of the surface of the object at a time when the excess thickness caused by the filler material blurs the etched patterns and surface reliefs.
- the second is the impossibility of escaping high constraints of cleanliness and environment before, during, and after coating or inking
- the third is the impossibility of escaping the never fully satisfactory compromises of compatibility between filler material (s) and material of the object to be treated. As a result of different initial resistances to temperature, chemicals, abrasion, shock, UV, the materials evolve in a way often unpredictable and counteract the precautions taken to eliminate the risks of delamination following differential expansion, and the other risks of yellowing, corrosion, crazing, scratches, etc.
Les procédés de traitement direct de surface mettent généralement en oeuvre des phénomènes d'adhérence chimique s'exerçant soit sur l'objet par érosion et/ou fusion chimique, soit sur le matériau d'apport par polymérisation suractivée (encres et vernis séchés par rayonnement UV ou IR), ou adjonction de colle (Brevet Français no 2.252.743 du 26.12.1973).The direct surface treatment methods generally use chemical adhesion phenomena exerted either on the object by erosion and / or chemical fusion, or on the filler material by overactivated polymerization (inks and varnishes dried by radiation UV or IR), or adding glue (French Patent No. 2252743 of 12/26/1973).
Les procédés de traitement indirect de surface ont pour caractéristique de ne pas traiter directement la surface, mais de traiter plutôt la masse épidermique sous-jacente à la surface des objets traités. Ils soumettent les objets précités à l'action gonflante de solvants ou mélanges de solvants puissants tels que: le tétrahydrofurane, la cyclohexanone, la diméthylformiamide, le sulfure de carbone, le chloroforme, l'alcool butylique, le trichlorotrifluoroéthane (fréon 113), le chlorure de méthylène, etc... L'effet de rétraction suivant l'effet transitoire de dilatation fait participer le matériau plastique de l'objet traité à la retenue des additifs sélectionnés, sans solliciter la surface apparente dudit objet. Les multiples déplacements physiques de l'épiderme de l'objet provoqués par un phénomène chimique génèrent un phénomène mécanique d'adhérence autorisant une insertion dans la masse épidermique d'additifs liquides et solubles, par immersion hors oxygène et humidité ambiante (Brevet Français No 1.312.260 du 13.01.62), (Brevet Européen N° 0.134.523 du 23.07.84 ou Brevet US N° 520.241 du 04.08.83), ou une insertion dans la masse épidermique d'additifs semi-liquides et non totalement solubles (encres vinyliques), sans immersion, par action mécanique d'une friction à la brosse de soie (Demande de Brevet Français N° 86.16621 du 27.11.86).The characteristic of indirect surface treatment methods is not to directly treat the surface, but rather to treat the epidermal mass underlying the surface of the treated objects. They subject the aforementioned objects to the swelling action of solvents or mixtures of powerful solvents such as: tetrahydrofuran, cyclohexanone, dimethylformiamide, carbon sulfide, chloroform, butyl alcohol, trichlorotrifluoroethane (freon 113), methylene chloride, etc. The retraction effect following the transient expansion effect makes the plastic material of the treated object participate in the retention of the selected additives, without stressing the apparent surface of said object. The multiple physical displacements of the epidermis of the object caused by a chemical phenomenon generate a mechanical phenomenon of adhesion allowing an insertion into the epidermal mass of liquid and soluble additives, by immersion except oxygen and ambient humidity (French Patent N o 1,312,260 of 13.01.62), (European Patent N ° 0.134.523 of 23.07.84 or US Patent N ° 520.241 of 04.08.83), or an insertion into the epidermal mass of semi-liquid and not completely soluble additives (vinyl inks), without immersion, by mechanical action of a friction with a bristle brush (French Patent Application N ° 86.16621 dated 27.11.86).
Les deux premiers procédés de traitement indirect de surface précités présentent l'avantage de ne pas modifier l'aspect initial de l'objet traité et de respecter, par exemple, une surface granuleuse, veinée, gravée, martelée, mais présentent les inconvénients suivants:
- inaptitude totale à traiter autre chose que la surface entière d'un objet. La consommation en additifs est au minimum doublée, et les objets de très fortes dimensions ne trouvent pas de cuves aptes à les recevoir pour traitement.
- inaptitude totale à traiter un objet s'il est solidarisé avec d'autres objets encombrants ou vulnérables aux agents chimiques du traitement de surface.
- exigence d'investissements élevés en surfaces couvertes et équipements (cuves, moyens de levage, moyens de chauffage et de ventilation, ...).
- obligation de nettoyer les objets pour ne pas polluer rapidement les bains.
- inaptitude à traiter de petites quantités d'objets ayant des exigences de traitement différentes, L'immersion exige des bains volumineux et donc coûteux, que l'on ne peut gaspiller par des transvasements et rinçages de cuve fréquents.
- adhérence très vulnérable des additifs. Leur solubilité aux solvants exigée par le procédé de traitement les rend vulnérables aux agressions chimiques ultérieures au traitement,
- adhérence très vulnérable des additifs. Leur nature liquide en solution avantage leur pénétration dans la masse épidermique de l'objet, mais les rend inaptes à utiliser les effets mécaniques de rétension provoqués par la rétraction consécutive à la dilatation de l'épiderme.
- neutralisation partielle des effets recherchés par les additifs liquides sélectionnés. L'évaporation massive des solvants vide partiellement les cavités et/ou aspérités microscopiques, dépose en couche mince les additifs sur la seule surface interne des cavités ou sur la seule surface tourmentée des aspérités, les éloigne de la surface visible de l'objet traité et crée ainsi un espace prêt à accueillir des additifs indésirables, saletés, poussières, La conjonction de l'éloignement des additifs et de l'aptitude à l'encrassement amplifie encore cet affaiblissement des effets du traitement de surface.
- inaptitude à sosutraire un additif indésirable incrusté dans l'épiderme (poussière, saleté) par suite de la pression du bain exercée sur l'objet.
- restriction du choix des additifs aux seuls additifs solubles, à l'exclusion des colles et agents adhésifs solubles.
- total inability to process anything other than the entire surface of an object. The consumption of additives is at least doubled, and very large objects do not find tanks capable of receiving them for treatment.
- total inability to treat an object if it is secured to other bulky objects or vulnerable to chemical agents of surface treatment.
- high investment requirement in covered areas and equipment (tanks, lifting means, heating and ventilation means, etc.).
- obligation to clean objects so as not to quickly pollute the baths.
- inability to process small quantities of objects with different treatment requirements, Immersion requires large and therefore expensive baths, which cannot be wasted by frequent tank transfers and rinses.
- very vulnerable adhesion of additives. Their solubility to solvents required by the treatment process makes them vulnerable to chemical attack after treatment,
- very vulnerable adhesion of additives. Their liquid nature in solution favors their penetration into the epidermal mass of the object, but makes them unfit to use the mechanical effects of retension caused by the retraction consecutive to the dilation of the epidermis.
- partial neutralization of the effects sought by the selected liquid additives. The massive evaporation of the solvents partially empties the cavities and / or microscopic asperities, deposits in a thin layer the additives on the only internal surface of the cavities or on the only tormented surface of the asperities, removes them from the visible surface of the treated object and thus creates a space ready to accommodate unwanted additives, dirt, dust. The combination of the remoteness of the additives and the ability to clog further amplifies this weakening of the effects of the surface treatment.
- inability to remove an undesirable additive embedded in the epidermis (dust, dirt) due to the pressure of the bath exerted on the object.
- restriction of the choice of additives to soluble additives only, excluding soluble glues and adhesive agents.
Le troisième procédé de traitement indirect de surface à la brosse de soie présente lui aussi l'avantage de respecter l'aspect initial de l'objet traité mais également les avantages supplémentaires d'être plus souple d'emploi en ne traitant que les surfaces sélectionnées, et en n'exigeant ni démontage ni nettoyage superficiel de l'objet. Il présente par contre les désavantages suivants:
- restriction du choix des additifs aux seules encres vinyliques aptes à former un revêtement coloré, sans aucune utilisation d'agents adhésifs ou de colles.
- adhérence vulnérable des additifs. Pour que la pénétration dans la masse épidermique des additifs insolubles présents dans l'encre vynilique ne soit pas avantagée au détriment de leur rétension dans les cavités ou les aspérités microscopiques rétractées, il faut un compromis entre faibles particules microscopiques favorables à l'insertion et fortes particules microscopiques favorables à la rétension. L'arbitrage se porte sur l'exclusion des plus faibles et plus grosses granulométries avec, pour conséquence, des effets de rétension mécanique et d'insertion moyens et jamais optimisés.
- adhérence vulnérable des additifs. Les additifs insolubles sont en suspension dans des additifs solubles et donc vulnérables aux agressions chimiques ultérieures au traitement.
- viscosité trop forte pour application par aérosol ou vaporisation, et trop faible pour suppression des coulures sur pièces verticales.
- inaptitude à soustraire un additif indésirable incrusté dans l'épiderme (poussière, saleté), par suite de la pression exercée par les fibres de la brosse de soie.
- inaptitude à traiter un objet plastique revêtu d'une couche d'apprêt sans détruire et l'apprêt et l'aspect de surface de l'objet ainsi apprêté.
- restriction of the choice of additives only to vinyl inks capable of forming a colored coating, without any use of adhesive agents or glues.
- vulnerable adhesion of additives. So that the penetration into the epidermal mass of the insoluble additives present in vinyl ink is not favored to the detriment of their retention in the microscopic retracted cavities or asperities, there is a compromise between small microscopic particles favorable to insertion and strong microscopic particles favorable to retention. The arbitration is based on the exclusion of the smallest and largest particle sizes with, as a consequence, mechanical retention and insertion effects that are average and never optimized.
- vulnerable adhesion of additives. Insoluble additives are suspended in soluble additives and therefore vulnerable to chemical attack after treatment.
- viscosity too high for application by aerosol or spray, and too low for removing streaks on vertical parts.
- inability to remove an undesirable additive embedded in the epidermis (dust, dirt), due to the pressure exerted by the fibers of the bristle brush.
- inability to process a plastic object coated with a primer layer without destroying both the primer and the surface appearance of the object thus primed.
Le nouveau procédé de traitement indirect de surface, objet de la présente invention, vise à corriger les inconvénients et insuffisances des procédés directs et indirects existants.The new indirect surface treatment method, object of the present invention, aims to correct the drawbacks and inadequacies of the existing direct and indirect methods.
L'invention vise non plus seulement à adjoindre et/ou modifier des matériaux d'apport, mais à en soustraire. Elle utilise l'effet de dilatation de l'épiderme de l'objet pour désincruster les additifs indésirables, les mouiller et les extraire par utilisation de l'effet capillaire d'une éponge ou matière spongieuse pressée contre la surface de l'objet. Elle devient ainsi le premier procédé de nettoyage de l'épiderme d'un objet.The invention no longer aims only to add and / or modify filler materials, but to subtract therefrom. It uses the effect of dilation of the epidermis of the object to unclog unwanted additives, wet them and extract them by using the capillary effect of a sponge or spongy material pressed against the surface of the object. It thus becomes the first method of cleaning the epidermis of an object.
L'invention permet l'insertion d'additifs sélectionnés en même temps que l'extraction des additifs indésirables. L'effet de dilatation est suffisamment long pour que les deux opérations aient lieu avant l'amoroe de l'effet de rétraction, donnant l'impression d'une seule action sélective et non pas de deux actions simultanées.
L'invention devient ainsi le premier désincrustant sélectif régénérateur de surface.
L'invention corrige la vulnérabilité de l'adhérence des additifs liquides, semi-liquides, et solides, en leur adjoignant des matériaux de préférence adhésifs, aptes à remplir les cavités et aspérités microscopiques à l'état fluide, et durcir en épousant la forme de ces cavités et aspérités, de façon à n'être plus vulnérables à une expulsion fortuite non souhaitée. Les additifs liquides peuvent pour la première fois bénéficier des effets mécaniques de rétension provoqués par la rétraction de l'épiderme de l'objet traité et accroître leur efficience en se rapprochant de la surface tout en étant mieux protégés puisque plus difficiles à occulter par les corps indésirables dont on a supprimé le terrain d'accueil privilégié. Les additifs semi-liquides et solides peuvent pour la première fois être sélectionnés dans les granulométries les plus faibles et améliorer simultanément ainsi leur pénétration et leur rétension. Ces objectifs contradictoires ne pouvaient être simultanément atteints et exigeaient des compromis excluant les granulométries les plus fines qui étaient favorables à l'insertion mais inaptes à utiliser l'effet de rétension produit par la rétraction de l'épiderme de l'objet traité.The invention allows the insertion of selected additives at the same time as the extraction of undesirable additives. The dilation effect is long enough for the two operations to take place before the retraction effect begins, giving the impression of a single selective action and not of two simultaneous actions.
The invention thus becomes the first selective surface regenerating descaler.
The invention corrects the vulnerability of the adhesion of liquid, semi-liquid, and solid additives, by adding to them preferably adhesive materials, capable of filling the microscopic cavities and asperities in the fluid state, and hardening by conforming to the form. of these cavities and asperities, so as to no longer be vulnerable to an unwanted accidental expulsion. Liquid additives can for the first time benefit from the mechanical retention effects caused by the retraction of the epidermis of the treated object and increase their efficiency by approaching the surface while being better protected since they are more difficult to conceal by the body. undesirable whose privileged reception area has been removed. Semi-liquid and solid additives can for the first time be selected in the smallest particle sizes and thus simultaneously improve their penetration and retention. These contradictory objectives could not be simultaneously achieved and required compromises excluding the finest particle sizes which were favorable for insertion but unable to use the retaining effect produced by the retraction of the epidermis of the object treated.
L'invention vise à obtenir une résistance particulière aux hydrocarbures, à l'eau, et aux produits lessiviels, pour certaines applications. Une distinction est donc faite entre la solubilité des additifs avant durcissement ou après durcissement, la fluidité maximale étant recherchée en première phase, et l'insolubilité maximale en dernière phase.The invention aims to obtain a particular resistance to hydrocarbons, water, and detergents, for certain applications. A distinction is therefore made between the solubility of the additives before hardening or after hardening, the maximum fluidity being sought in the first phase, and maximum insolubility in the last phase.
L'invention donne accès, à tître non restrictif et en sus du traitement de nettoyage, à des traitements de surface très nombreux, rapides, simples ou combinés, parfaitement localisés, applicables in situ, sans infrastructure et sans démontage, visant à soustraire, modifier ou ajouter, des agents stabilisateurs aux U.V., à la chaleur, à l'électricité statique; des agents retardateurs de flammes, de fumées, de gaz toxiques; des agents moussants, anti-oxydants, fluorescents, réflecteurs, absorbants, conducteurs de l'électricité, isolants, résistants à l'abrasion, abrasifs, lubrifiants; des colorants, pigments, teintures, etc...The invention gives access, without limitation and in addition to the cleaning treatment, to very numerous surface treatments, rapid, simple or combined, perfectly localized, applicable in situ, without infrastructure and without disassembly, aiming to remove, modify or add stabilizers to UV, heat, static electricity; flame retardants, smoke retardants, toxic gases; foaming agents, antioxidants, fluorescers, reflectors, absorbents, electricity conductors, insulators, abrasion resistant, abrasives, lubricants; dyes, pigments, dyes, etc ...
L'invention permet, grace à son aptitude à utiliser pleinement l'effet de rétraction, de moduler l'agressivité de la phase 1 vis à vis de l'épiderme à traiter (exemple non restrictif d'une attaque variable de l'épiderme selon la nature et la concentration des solvants), et de rendre le nouveau procédé accessible à des modes d'application plus rapides, moins polluants et plus souples d'emploi.The invention allows, thanks to its ability to fully use the retraction effect, to modulate the aggressiveness of phase 1 with respect to the epidermis to be treated (non-restrictive example of a variable attack of the epidermis according to the nature and concentration of the solvents), and to make the new process accessible to faster, less polluting and more flexible methods of application.
L'invention, par sa souplesse d'emploi et son aptitude à utiliser pleinement l'effet de rétraction, peut utiliser les modes d'application par immersion et par friction à la brosse de soie, mais aussi par vaporisation (pistolet, pompe, bombe, spray, etc... ), par friction à l'éponge, au gant, à la brosse de fibres végétales, au rouleau, etc...The invention, by its flexibility of use and its ability to make full use of the retraction effect, can use the modes of application by immersion and by friction with the bristle brush, but also by spraying (gun, pump, spray can , spray, etc ...), by friction with a sponge, glove, vegetable fiber brush, roller, etc ...

Selon les buts à atteindre et les méthodes d'application retenues, certaines phases peuvent paraître conjointes ou séparées, ainsi que plus ou soins longues.Depending on the goals to be achieved and the application methods selected, certain phases may appear to be joint or separate, as well as more or long-term care.
Le mélange durcisseur est constitué d'au moins deux agents: l'additif à insérer qui est très fluide pour en faciliter l'insertion et l'adhésif ou l'agent chimique capable d'agglomérer l'additif après sa pénétration dans les cavités et/ou aspérités microscopiques. L'agglomérat entre adhésif et additif liquide, semi-liquide ou solide, reconstitue des particules in situ remarquables par leur calibre supérieur à celui des voies d'accès aux cavités et aspérités précitées, et par leur forme épousant parfaitement celles des dites cavités et aspérités.The hardening mixture consists of at least two agents: the additive to be inserted which is very fluid to facilitate insertion and the adhesive or chemical agent capable of agglomerating the additive after it has penetrated into the cavities and / or microscopic roughness. The agglomerate between adhesive and liquid, semi-liquid or solid additive, reconstitutes particles in situ which are remarkable for their size greater than that of the access routes to the abovementioned cavities and asperities, and for their shape perfectly matching those of said cavities and asperities. .
Les mélanges durcisseurs, en dépit de fortes différences pouvant exister dans leur formulations, leurs conditions de stockage, leurs conditionnements et leurs modes d'emploi, ont tous une viscosité évolutive qui demeure la plus faible possible jusqu'à leur mise en place et se renforce alors en phase 3 jusqu'au durcissement complet en phase 4, mais suffisamment lentement en cette dernière phase pour permettre la correction des bévues éventuelles par une phase optionnelle 5.The hardening mixtures, in spite of strong differences which may exist in their formulations, their storage conditions, their packaging and their instructions for use, all have an evolutionary viscosity which remains as low as possible until their installation and becomes stronger. then in phase 3 until complete hardening in phase 4, but slowly enough in this last phase to allow correction of any blunders by an optional phase 5.
Les mélanges durcisseurs, en dépit de fortes différences pouvant exister dans leurs formulations, leurs conditions de stockage, leurs conditionnements et leurs mode d'emploi, ont tous une solubilité évolutive qui ne crée pas de conditions défavorables au bon déroulement des phases 1, 2, 3, 4, 5, et permet même de moduler l'agressivité de la phase 1 vis à vis de l'épiderme à traiter, mais apporte après le durcissement total de la phase 4 une insolubilité à la plupart des agressions chimiques prévisibles dont on aura voulu préserver les objets traités, et parfois même une insolubilité à certains des solvants qui maintenaient les mélanges durcisseurs à l'état fluide pendant les phases 1, 2, et 3.The hardener mixtures, despite strong differences which may exist in their formulations, their storage conditions, their packaging and their instructions for use, all have an evolving solubility which does not create unfavorable conditions for the smooth running of phases 1, 2, 3, 4, 5, and even makes it possible to modulate the aggressiveness of phase 1 with respect to the epidermis to be treated, but brings, after the total hardening of phase 4, insolubility to most of the predictable chemical aggressions of which wanted to preserve the objects treated, and sometimes even a insolubility to some of the solvents which kept the hardening mixtures in the fluid state during phases 1, 2, and 3.

- Process according to Claims 1 to 4, characterised by the fact that stage D consists either of a reaction between the components of the hardening mixture with oxygen and moisture, or of a reaction of the components of the hardening mixture with heat or cold, or of a reaction with a modified, acid, basic or neutral gaseous atmosphere, or of a reaction with natural or artificial light, or of a reaction with radiation, for example ultra-violet radiation, or of the elimination of one of the components of the mixture, for example by evaporation, chemical conversion, drying, or selective suction, or of the release of a fixed, inhibited reagent or catalyst, or of any other means capable of producing the required hardening.
- Process according to Claims 1 to 5, characterised by the fact that the hardening mixture consists of at least two agents: the additive to be introduced which is highly fluid to facilitate introduction and the adhesive or chemical agent capable of agglomerating the additive after its penetration into the microscopic cavities and/or roughnesses, in such a way that the preportions of the adhesive and the liquid, semi-liquid or solid additive are chosen to reconstitute particles in situ notable for their size being greater than that of the access paths to the above-mentioned cavities and roughnesses, and for their shape which perfectly matches those of the said cavities and roughnesses.
- Process according to Claims 1 to 6, characterised by the fact that the hardening mixtures all have a variable viscosity which remains as low as possible until their introduction and then increases during stage C up to complete hardening in stage D, but sufficiently slowly during this latter phase to allow correction of any mistakes in an optional stage E.
- Process according to Claims 1 to 7, characterised by the fact that the hardening mixtures all have a variable and selective solubility which does not create conditions unfavourable to the satisfactory completion of stages A, B, C, D and E, the said solubility declining from a maximum level capable of modulating the attack of stage A with regard to the surface skin to be treated up to total disappearance of the soluble state after the hardening of stage D, the said solubility being preferably selective so as to be a maximum during stages A, B and C, without being vulnerable to some of the solvents maintaining the hardening mixtures in the fluid state and to be zero in stages D and E, without being vulnerable to most of the foreseeable chemical attacks from which it is necessary to protect the objects treated.
- Process according to Claims 1 to 8, characterised by the fact that in addition to the cleaning treatment it permits the addition of agents intended to remove, modify or add agents giving stability against UV, heat, static electricity, flame retardants, smoke, toxic gases, foaming, anti-oxidant, fluorescent, reflective, absorbant, electrically conducting, insulating, abrasion-resistant, abrasive or lubricating agents, colouring matter, pigments and dyes.
- Process according to Claim 1, characterised by the fact that it can be applied not only to the skin layers of materials suitable for modification by the creation of microscopic cavities and/or roughnesses but also to skin areas in materials comprising microscopic pores and/or roughnesses such as plastic resins, rubber, leather or other materials satisfying the above criteria.
