Abstract

Device making it possible to retain the excess of the solution obtained by the absorption of atmospheric moisture by the calcium chloride - absorbent powder mixture, this mixture being held in an enclosure which is permeable to moist air but impervious to the solution. The excess solution or that originating from the wet mixture does not pass through the enclosure.

Description

La présente invention concerne un pcrf ectionnclncn t aux brevets 2583990 - 2506175 et à la demande de brevet 90 02611 pour un usage plus efficace du dispositif permettant d'absorber la totalité de la solution obtenue par un absorbeur d'humidité à base de chlorure de calcium.The present invention relates to a pcrf ectionnclncn t to patents 2583990 - 2506175 and to patent application 90 02611 for a more effective use of the device for absorbing all of the solution obtained by a moisture absorber based on calcium chloride .

En effet si l'emploi d'une poudre absorbante pour bloquer la solution obtenue par l'absorption de l'humidité par le chlorure de calcium permet d'éviter l'écoulement, le renversement de cette solution, le mélange chlorure de calcium - poudre absorbante ne peut être intime du fait de la différence de densité, et qu'il s'agit d'un mélange et non d'un enrobage. Il peut toujours y avoir une partie de la solution qui échappe à la poudre absorbante, même dans le cas de la demande de brevet 90 02611 si l'ensemble se renverse.Indeed if the use of an absorbent powder to block the solution obtained by the absorption of moisture by calcium chloride makes it possible to avoid the flow, the spilling of this solution, the mixture of calcium chloride - powder absorbent can not be intimate because of the difference in density, and it is a mixture and not a coating. There may still be a part of the solution which escapes from the absorbent powder, even in the case of patent application 90 02611 if the assembly spills.

Cette vapeur d'eau est absorbée par le chlorure de calcium, la solution obtenue est absorbée par la poudre absorbante mais s'il y a excédent ou simplement contact avec la gaine, de la solution, celle-ci passe au travers.This water vapor is absorbed by the calcium chloride, the solution obtained is absorbed by the absorbent powder but if there is excess or simply contact with the sheath, of the solution, the latter passes through.

Le perfectionnement consiste à utiliser comme gaine enveloppant le mélange de chlorure de calcium et d'une poudre absorbante un matériau imperméable à la solution mais perméable à l'air humide.The improvement consists in using as a sheath enveloping the mixture of calcium chloride and of an absorbent powder a material impermeable to the solution but permeable to humid air.

Dans l'exemple non limitatif suivant, la gaine est un nontissé en polypropylène dont la caractéristique est d'être imperméable à la solution mais perméable à l'air humide. In the following nonlimiting example, the sheath is a polypropylene nonwoven whose characteristic is to be impermeable to the solution but permeable to humid air.

Ce procédé nouveau est une sécurité supplémentaire qui permet de placer des sachets deshydratants suivant cette formule nouvelle entre les produits à protéger sans crainte de voir ces produits altérés par la solution de chlorure de calcium. This new process is an additional security which makes it possible to place desiccant sachets according to this new formula between the products to be protected without fear of seeing these products altered by the calcium chloride solution.

Ce procédé nouveau permet d'employer des mélanges plus riches en chlorure de calcium donc plus efficaces sans crainte d'écoulement de l'excès de la solution de chlorure de calcium. This new process makes it possible to use mixtures which are richer in calcium chloride and therefore more effective without fear of leaking the excess of the calcium chloride solution.

On introduit le mélange chlorure de calcium - poudre absorbante dans un sachet, constitué d'une gaine imperméable à la solution mais perméable à l'air chargé d'humidité, ayant une forme plate afin de pouvoir être placé entre des emballages. The calcium chloride-absorbent powder mixture is introduced into a sachet, consisting of a sheath impermeable to the solution but permeable to air laden with moisture, having a flat shape so that it can be placed between packages.

On introduit le mélange chlorure de calcium - poudre absorbante dans un sac constitué d'une gaine décrite comme cidessus et que l'on peut suspendre.  The calcium chloride-absorbent powder mixture is introduced into a bag consisting of a sheath described as above and which can be hung.
