Abstract

Method for fighting dampness in walls subjected to an electrical field and treated with one of the electro-physical drying methods such as electro-osmosis, electrophoresis, combined electro-osmosis-phoresis, etc. An intermediate screen is inserted between the wall zone subjected to the drying treatment and the object between which there exists an interfering electrical field and prevents the said field from being propogated as far as the treated wall.

Description

Procédé pour combattre l'humidité des murs soumis à un champ électrique.Method for combating humidity in walls subjected to an electric field.

La présente invention concerne un procédé pour combattre lthumidité montante des murs soumis à un champ électrique et traités par une des méthodes d'assèchement électro-physiques telles que I'électro-osmose, l'électrophorèse# l'électro-osmose-phorèse combinée etc
Il a. été constaté qu a certains endroits les murs traités avec l'une des méthodes précitées ne perdaient pas -leur humidité à un degré identique aux zones voisines de ces endroits.Il a également été constaté que ce phénomène d'humidité persistante se manifeste surtout à proximité d'objets proches du mur considéré tels que des arbres, des armoires, des couches de revêtement localement décalées du mur en pierres ou briques, des couches d'air. humide, etc.. . Ces objets ont des potentiels propres différents de celui du mur humide de sorte qu'il s'établit un champ électrique perturba teur ou parasite entre ces objets et les zones de mur situées en face desdits objets, ce champ électrique influençant de façon néfaste le bon fonctionnement de la méthode de traitement électro-physique du mur probablement en agissant sur le champ électrique appliqué au mur par l'installation de traitement électro-physique.
The present invention relates to a method for combating the rising humidity of walls subjected to an electric field and treated by one of the electro-physical drying methods such as electro-osmosis, electrophoresis # combined electro-osmosis-phoresis, etc.
He has. It has been found that in certain places the walls treated with one of the abovementioned methods do not lose their humidity to a degree identical to the areas adjacent to these places. It has also been found that this phenomenon of persistent humidity is manifested especially near objects close to the wall in question such as trees, cupboards, layers of coating locally offset from the stone or brick wall, layers of air. wet, etc. These objects have their own potentials different from that of the wet wall so that a disturbing or parasitic electric field is established between these objects and the wall areas located opposite said objects, this electric field adversely influencing the good operation of the electro-physical treatment method for the wall, probably by acting on the electric field applied to the wall by the electro-physical treatment installation.

La présente invention a pour but de supprimer cet inconvénient. The object of the present invention is to eliminate this drawback.

Ce but est atteint conformément à l'invention du fait qu'on intercale entre la zone de mur et l'objet entre lesquels existe un champ électrique perturbateur un écran intermédiaire qui empêche le dit champ électrique perturbateur de se propager jusqu'au mur traité par une méthode électro-physique d'assèchement. This object is achieved in accordance with the invention due to the fact that an intermediate screen is inserted between the wall area and the object between which there is a disturbing electric field which prevents said disturbing electric field from propagating to the wall treated by an electro-physical method of drying.

Comme écran intermédiaire peuvent etre utili sés des écrans diélectriques, c'est-à-dire électrique ment isolants, ou des écrans électriquement conducteurs. As an intermediate screen, dielectric screens, that is to say electrically insulating screens, or electrically conductive screens can be used.

Dans ce dernier cas, l'écran conducteur doit etre isolé électriquement par rapport à l'installation utilisée pour la mise en oeuvre de la méthode de traitement électro-physique et être mis å la masse. t'écran conducteur d'électricitë peut être constitué par une tôle ou une grille bonne conductrice d'électricité. Il peut également être avantageux de relier à la masse 1≈écran diélectrique pour éviter la formation d'une différence de potentiels trop importante entre lui-même et le mur.In the latter case, the conductive screen must be electrically insulated from the installation used for the implementation of the electro-physical treatment method and be grounded. the electrically conductive screen can consist of a sheet or a grid that is good at conducting electricity. It may also be advantageous to connect the dielectric shield to ground to avoid the formation of a too large potential difference between itself and the wall.

Pour éviter qu'une couche de revêtement mural défectueuse, par exemple humide et écartée du mur ne puisse #tre à l'origine d'un champ électrique perturbateur, il convient d'appliquer l'écran directement contré le mur nu. L'écran intermédiaire peut constituer lui même la couche de revêtement extérieur et/ou inférieur du mur et être réalisé en tant que couche de peinture isolante, d'enduit, de crépi, de parement etc.. . Bien entendu, la couche de parement pourra également être montée à une certaine distance du mur avec des éléments de support isolés par rapport au mur.Pour la fabrication des peintures ou autres rezêtements diélectriques on pourra utiliser toutes les matières liquides et solides électriquement isolantes ou au moins enrobées de couches isolantes lorsqutil s'agit de matières solides granuleuses non isolantes. Les liquides utilisés peuvent être durcissables ou susceptibles de s'évaporer à l'air ambiant. On peut utiliser notamment des bitumes, des résines synthétiques à grande résistance électrique telles que les silicones, des charges isolantes en poudres ou grains telles que du sable, du talc, des granulés synthétiques etc..To avoid a defective layer of wall covering, for example damp and away from the wall, being able to cause a disturbing electric field, the screen should be applied directly against the bare wall. The intermediate screen can itself constitute the outer and / or lower coating layer of the wall and be produced as a layer of insulating paint, plaster, plaster, facing, etc. Of course, the facing layer can also be mounted at a certain distance from the wall with insulating support elements with respect to the wall. less coated with insulating layers when they are non-insulating granular solids. The liquids used may be hardenable or may evaporate to the ambient air. It is possible in particular to use bitumens, synthetic resins with high electrical resistance such as silicones, insulating fillers in powders or grains such as sand, talc, synthetic granules, etc.

Avantageusement, on peut utiliser une grille qui comporte un côté conducteur et un coté non conducteur d'électricité et qui est disposée entre la zone d'in fluence de l'installation électro-physique d'assèchement de mur et le champ électrique perturbateur de telle sorte que le côté non conducteur d'électricité de la grille soit tourné vers le champ d'action de l'installation d'assèchement, que la mise à la masse du côté conducteur de la grille tourné vers le champ perturbateur n'ait pas de liaison avec ladite installation d'assèchement et que la résistance du circuit de mise à la masse de la grille soit inférieure à celle du circuit de mise à la masse de l'installation d'assèchement. Ainsi, le champ électrique perturbateur peut être supprime d'une manière efficace. Advantageously, it is possible to use a grid which has a conductive side and a non-conductive side of electricity and which is arranged between the zone of influence of the electro-physical wall drying installation and the disturbing electric field of such so that the non-electrically conductive side of the grid faces towards the field of action of the dewatering installation, so that the conductive side of the grid faces towards the disturbing field does not have connection with said stripping installation and that the resistance of the grid earthing circuit is lower than that of the earthing circuit of the stripping installation. Thus, the disturbing electric field can be effectively suppressed.

L'objet de la présente invention-peut subir un certain nombre de modifications sans que l'on sorte pour cela du cadre de protection défini par les revendications annexées.  The object of the present invention can undergo a number of modifications without departing from the protective framework defined by the appended claims.
