Definitions
- the present invention relates to a device for regulating relative humidity.
- the device can however be used for many other applications.
- Patent No. FR 2 656 848 describes a paint bucket comprising a cover with seal fitted with a humidifier provided with holes allowing the solvent to pass into the interior of the bucket, which is soaked in a sponge disposed in said humidifier.
- the device according to the present invention makes it possible to compensate for the evaporation of water or of solvents contained in a product in order to delay, slow down or even stop its drying and hardening in order to maintain its initial state before evaporation, thus retaining its original malleability. . It also makes it possible to re-impregnate a product with water or solvents, if its nature allows it, to restore it to a certain malleability or, conversely, to extract water or solvent vapors from the content of a container.
- It consists of a closed enclosure equipped with a relative humidity regulating system made of a material which can be impregnated with liquid and capable of adsorbing or desorbing the vapor of this liquid, this material comprising on one of its faces a membrane, permeable to vapor but not to liquid, and the external face of which is hydrophobic, the other face of the adsorbent-desorbent material being able to comprise a membrane permeable to vapor in one direction making it possible to make the system self-humidifying or self-drying according to the direction of permeability of this membrane.
- FIG. 1 shows in vertical section an enclosure comprising at its upper part a humidity regulating device with liquid reserve
- FIG. 2 represents, under the same conditions, a paint palette with a tight lid with a liquid reserve humidity regulating device placed at the bottom of the enclosure
- FIGS. 3 and 4 are cross sections of reserve humidity regulators of liquid intended to maintain a humidity respectively higher and lower than that prevailing outside the enclosure equipped with the humidity regulating device.
- the device consists of the association of a membrane 1 permeable to water vapor comprising a hydrophobic face 2, and of a layer 3 of adsorbent-desorbent material which can be conditioned at a humidity level. relative determined, the whole being included in a closed enclosure 4.
- the adsorbent-desorbent material 3 can be placed in a sealed water tank with filling opening 5 internal (FIG. 2) or external (FIG. 1).
- the material adsorbs the water poured into this tank until saturation and desorbs it at the desired relative humidity level through the membrane 1.
- the latter is arranged against one face of the layer 3 so as to present a hydrophobic free external surface .
- the system compensates for the increase or decrease in relative humidity according to a proportion related to the volume of the enclosure 4 which it is desired to maintain at a stable relative humidity (FIGS. 1 and 2).
- This arrangement can in particular make it possible to produce a paint palette 6 consisting of a bottom 7 and a sealed cover 8 hinged or removable.
- the humidity regulating device extends over the entire surface of the bottom and the paint 9 is deposited directly on the hydrophobic surface of the membrane 1, which, combined with the maintenance of humidity inside the enclosure formed by the bottom 7 and the cover 8, allows to keep for a prolonged period the paint 9 in the state in which it was at the outlet of the tube.
- This palette can be used for all water-based paints (acrylic, gouache, watercolor, etc.) ( Figure 2).
- the upper peripheral surface of the water tank may have holes promoting the evaporation of the liquid so as to increase the humidity inside the enclosure.
- a porous plate can be inserted between the bottom of the enclosure
- layer 3 of adsorbent-desorbent material communicating with a filling opening or an external reservoir so as to avoid saturation of water in layer 3.
- a second inverted regulating device is placed in the cover and arranged so as to promote the passage of steam from the inside to the outside.
- This arrangement makes it possible to humidify certain objects or products deposited on the hydrophobic surface of the membrane 1 of the bottom regulator assembly. It can in particular be applied to treat delicate designs.
- a porous plate possibly rigid (not shown), may advantageously be provided between said membrane and the adsorbent-desorbent layer 3.
- the liquid reservoir is arranged below the membrane 1 / adsorbent-desorbent layer 3 assembly and the moisture is transmitted by capillarity to the membrane 1 by means of a sheet of porous material placed under this layer and extended downwards so as to soak in the liquid.
- This variant can in particular be used to make enclosures making it possible to keep potted plants for an extended period without watering.
- the humidity regulator can either be placed in the lower or upper part of the enclosure. It can in particular be located in the lid 10 of a container such as a container for preserving paint 11, glue, plastic mass or other products which tend to dry.
- a humidity indicator 12 can be provided, in contact with the adsorbent-desorbent material and visible from the outside, making it possible to know at any time whether the quantity of water in reserve is sufficient (FIG. 1).
- the humidity regulating device is manufactured with the layer 3 of adsorbent-desorbent material sealed between a membrane 1 permeable to water vapor in both directions on one side, and a second membrane 13 permeable to water vapor in only one direction directed towards the back of the adsorbent material (arrows 14), the system becomes self-humidifying and does not require a reserve of liquid. It acts as a humidity condenser towards the outside of the two-way diaphragm 1 ( Figure 3).
- the layer 3 of adsorbent-desorbent material will advantageously consist of unsaturated salts or of a silica gel which can be conditioned for a desired relative humidity level by prolonged passage in an oven maintained at this rate, and the membrane 1 made of polytetrafluoroethylene (PTFE ) expanded.
- PTFE polytetrafluoroethylene
- This material has a high permeability to gases while being perfectly impermeable to liquids.
- its surface is perfectly hydrophobic and non-staining, which makes this material particularly effective in the case of the paint palette 6, which is thus washable and reusable immediately.
- the membrane 1 can be formed a very thin film or a more or less thick porous sheet.
- the device described can give rise to very numerous applications in different fields. With a watertight water reserve, it can equip, for example, cigar boxes, clay conservation boxes, display cases, boxes for seedlings and cuttings, or for presentation of flower arrangements, bonsai trees, etc. .
- a second membrane 13, 13 ′ permeable in one direction it can be used for the preceding applications, without addition of water, and also allows the production of wall panels in contact with the outside and intended for moisture compensation rooms that are too dry (central heating) or, on the contrary, too humid. It can also serve as a water trap in hot countries or as a permanent auto-desiccator of various containers such as boxes, cans or sachets.
- the system which is the subject of the invention with a sealed liquid reserve can also be used to prevent drying of non-aqueous products and in particular for pallets of varnish paint, or quick-drying oil paint, or even for pots of glycerophthalic paint, varnish, for the conservation of paste waxes.
- the liquid reserve is filled with a mixture of water and a proportion tolerable by the membrane 1 of solvent, this membrane, as well as the adsorbent-desorbent material being produced from products suitable for water.
- the non-aqueous solvent may also not be diluted in water, the layer 3 of adsorbent material and the membrane 1 then being produced in specific materials compatible with this solvent.
