Description
La présente invention concerne un nouveau bain et procédé de PHOSPHATATION contre la rouille et la corrosion des pièces métalliques, fer, fonte ou acier.The present invention relates to a new bath and PHOSPHATION process against rust and corrosion of metal parts, iron, cast iron or steel.
Notre invention est une méthode très efficace contre la rouille et de plus, constitue une base d'accrochage exceptionnelle pour peinture, teinture, bisulfure de molybdène MOS/2.Our invention is a very effective method against rust and moreover, constitutes an exceptional bonding base for painting, dyeing, molybdenum disulphide MOS / 2.
C'est à la suite de plusieurs années de recherches que le procédé a été mis au point, pour obtenir un résultat tout à fait satisfaisant pour son efficacité contre la rouille, et son aspect visuel, finition coloration noire - De plus cette méthode est très économique.It is after several years of research that the process was developed, to obtain a completely satisfactory result for its effectiveness against rust, and its visual appearance, finish black coloring - In addition this method is very economic.
Les pièces métalliques sont 1") Dégraissées aux vapeurs de TRICHLORETHANE commercialisé sous le nom
de SOLVETHENE (ou tout autre solvant convenant au nettoyage des pièces) 20) Sans autre opération, les pièces ainsi préparées peuvent subir le
traitement phosphatation
Le traitement consiste à Immerger les pièces dans le bain de phosphatation a mne température de 95 a C. Le temps dtimmersion varie de 10 à 20 minutes selon le traitement choisi, léger ou plus épais, cette dernière solution devant donner une protection plus efficace contre la rouille.The metal parts are 1 ") Degreased with TRICHLORETHANE vapors marketed under the name
SOLVETHENE (or any other solvent suitable for cleaning the parts) 20) Without any other operation, the parts thus prepared can undergo the
phosphating treatment
The treatment consists of immersing the pieces in the phosphating bath at a temperature of 95 to C. The immersion time varies from 10 to 20 minutes depending on the treatment chosen, light or thicker, the latter solution having to give more effective protection against rust.
Les pièces sont ensuite retirées du bain, puis séchées à la soufflette ou en étuve,
L'opération de phosphatation est terminée.The pieces are then removed from the bath, then dried in a blow gun or in an oven,
The phosphating operation is finished.
Les pièces ainsi traitées pourront recevoir un revetement de peinture, teinture, vernis, huile ou tout autres produits.The parts thus treated may receive a coating of paint, stain, varnish, oil or any other product.
Cette méthode est particulièrement souhaitable et recommandée pour ses qualités de base d'accrochage, notamment pour le bisulfure de molybdène
Elle n'écaille pas. This method is particularly desirable and recommended for its basic bonding qualities, in particular for molybdenum disulphide
It does not flake.
Notre méthode très simple dans sa conception est d'un prix de revient nettement inférieur à tous les autres produits actuels.Our very simple method in its conception is of a cost price clearly lower than all the other current products.
Ces produits étant tous d'importation ou fabriqués sous licence (frais de transports, problèmes de délais de livraison, risque de grèves,
règlements par virements inter-bancaires ou comptants).These products are all imported or manufactured under license (transport costs, delivery time problems, risk of strikes,
payments by inter-bank or cash transfers).
L'équipement pour l'utilisation de notre procédé est très simple et intéressant car ne necessite qu'une cuve de dégraissage et une cuve de phosphatation pour toute la réalisation du traitement.The equipment for the use of our process is very simple and interesting because it only requires a degreasing tank and a phosphating tank for the whole realization of the treatment.
L'entretien est minium
L'investissement est réalisé pour de très nombreuses années Le procédé est tout a fait inoffensif, et ne peut nuire a la santé des
personnes qui l'utilisent Ne demande pas mon personnel qualifié Il n'y a aucun risque de pollution, le bain n'étant jamais rejeté Il n'a aucune influence sur les propriétés physiques des métaux traités Le revêtement est de densité et d'épaisseur uniformes sur toute la
surface des pièces L'aspect des pièces est respecté.La surépaisseur de la couche est de
3 å su microns 2/3 å l'extérieur du métal, 1/3 à l'intérieur, fournissant
ainsi tne parfaite base d'accrochage Elle convient a tous les métaux, pièces msinéesss ressorts, aciers à haute
tension, les objets matricés, fondus, estampés, soit tous les aciers, fer,
fonte Alors que nombreuses autres méthodes exigent un rinçage des pièces après
traitement, cette opération se révèle totalement inutile avec notre pro
cédé de phosphatation Le prix ae revient du traitement est peu onéreux (fabriqué en France)
La cuve de phosphatation est en acier, de formes rectangulaires de dimensions permettant le meilleur usage, chauffée par l'électricité, le gaz ou la vapeur, calorifugée et toujours fermée d'un couvercle, afin d'éviter l'évaporation, la solution de traitement étant chauffée 24/24 h à la température constante de 95/98 C, contrôlée par thermostats. L'eau est fournie automatiquement ou manuellement, l'addition de produit de phosphatation est effectuée fréquemment, système à la convenance, et par petites quantités. Maintenance is minimal
The investment is made for many years. The process is completely harmless, and cannot harm the health of
people who use it Do not ask my qualified personnel There is no risk of pollution, the bath is never rejected It has no influence on the physical properties of the treated metals The coating is of density and thickness uniforms all over
surface of the parts The appearance of the parts is respected. The thickness of the layer is
3 å on microns 2/3 outside the metal, 1/3 inside, providing
thus a perfect attachment base It is suitable for all metals, mechanical parts, springs, high steels
tension, stamped, melted, stamped objects, i.e. all steels, iron,
While many other methods require parts to be flushed after
treatment, this operation is completely useless with our pro
ceded with phosphating The cost price of the treatment is inexpensive (made in France)
The phosphating tank is made of steel, rectangular shapes of dimensions allowing the best use, heated by electricity, gas or steam, insulated and always closed with a lid, in order to avoid evaporation, the solution of treatment being heated 24/24 h at a constant temperature of 95/98 C, controlled by thermostats. The water is supplied automatically or manually, the addition of phosphate product is carried out frequently, system at convenience, and in small quantities.
Le bain de phosphatation se régénère avec l'eau courante additionnée de produit, le niveau est contrôlé et rectifié régulièrement.The phosphating bath is regenerated with running water added with product, the level is checked and adjusted regularly.
Le contrôle du bain consiste à maintenir l'équilibre du point d'acidité par l'addition du produit de phosphatation après un simple titrage du degré d'acidité, qui est réalisé en prélevant un échantillon dans la cuve de phosphatation à l'aide d'une pipette, et d'effectuer un contrôle visuel dans une éprouvette avec une solution indicatrice de titrage.Bath control consists in maintaining the equilibrium of the acidity point by adding the phosphating product after a simple titration of the degree of acidity, which is carried out by taking a sample from the phosphating tank using '' a pipette, and carry out a visual check in a test tube with a titration indicator solution.
Cette opération d'une grande simplicité et fiabilité peut-être réalisée par une personne non qualifiée.This operation of great simplicity and reliability can be carried out by an unqualified person.
La cuve de phosphatation ne nécessite aucun entretien excessif, il suffit de nettoyer les dépôts au fond de la cuve, et la décalaminer environ tous les cinq ans.The phosphating tank does not require any excessive maintenance, it suffices to clean the deposits at the bottom of the tank, and to decarbonize it approximately every five years.
Notre procédé est d'une utilisation très simple, comportant 3 phases
Dégraissage des pièces
. TraItement dans le bain de phosphatation
. Séchage
Les anciennes formules de phosphatation à base de zinc fixaient très mal le bisulfure de molybdène, d'où écaillage,qui rendait les pièces impropres à l'usage demandé.Our process is very simple to use, comprising 3 phases
Degreasing of parts
. Treatment in the phosphating bath
. Drying
The old zinc-based phosphating formulas did not fix the molybdenum disulphide very well, hence flaking, which made the parts unsuitable for the required use.
Cette nouvelle formule à la particularité de fixer ce molybdène sans risque d'écaillage,
Le gros avantage de notre invention est aussi son coût, nettement inférieur aux prix de revient des antres procédés.This new formula has the particularity of fixing this molybdenum without risk of chipping,
The big advantage of our invention is also its cost, much lower than the cost price of other processes.
