Abstract

Cleaning process, especially for buildings and monuments, by projecting powder, characterised in that this powder consists of a powdered metal oxide whose particle size is smaller than 20 microns.

Description

L'invention concerne un procédé de nettoyage, notamment de bâtiments et monuments, par projection de poudre. The invention relates to a method of cleaning, in particular of buildings and monuments, by powder spraying.

Le procédé de l'invention est caractérisé en ce que cette poudre est constituée par de la poudre d'un oxyde de métal dont la granulométrie est inférieure à 20 microns. The method of the invention is characterized in that this powder consists of powder of a metal oxide whose particle size is less than 20 microns.

Suivant une autre caractéristique de l'invention, la poudre est constituée par de l'oxyde d'aluminium. According to another characteristic of the invention, the powder consists of aluminum oxide.

Ce procédé a pour but d'assurer le nettoyage par gommage, de matieres fragiles telles que le marbre et les revêtements divers de façades d'immeubles, ainsi que les surfaces sculptées telles que les fresques de monuments. Egalement, ce procédé peut être utilisé pour le nettoyage de glaces, des bâches en matière textile, d'objets en matiere plastique ou en métal, de papiers peints et de peintures. The purpose of this process is to ensure the cleaning by gumming, of fragile materials such as marble and the various coatings of facades of buildings, as well as the sculpted surfaces such as the frescoes of monuments. This method can also be used for cleaning glass, tarpaulins made of textile material, plastic or metal objects, wallpapers and paints.

Ce procédé met essentiellement en oeuvre de la poudre d'oxyde d'un métal et, notamment, d'oxyde d'aluminium dont la granulométrie est inférieure à 20 microns, cette poudre étant projetee par un jet d'air de puissance réglable et par l'intermédiaire d'une buse d'un pistolet à jet d'air comprimé. This process essentially uses oxide powder of a metal and, in particular, aluminum oxide whose particle size is less than 20 microns, this powder being projected by an air jet of adjustable power and by through a nozzle of a compressed air jet gun.

La faible granulométrie ainsi que la dureté de cette poudre, permettent le décollage des salissures recouvrant la surface à nettoyer, sans détériorer cette surface et particulièrement les surfaces sculptées des fresques des monuments historiques. The small particle size and the hardness of this powder allow the removal of dirt covering the surface to be cleaned, without damaging this surface and particularly the sculpted surfaces of the frescoes of historic monuments.

La projection de cette poudre à sec, c'està-dire à l'aide d'un jet d'air, permet de mettre ce procédé en oeuvre à l'intérieur des locaux pour le nettoyage des glaces, des peintures, papiers peints, boiseries, etc. qui peuvent être juxtaposés dans un local sans crainte que l'un d'entre eux ne soit abîmé. Spraying this powder dry, that is to say using an air jet, makes it possible to carry out this process inside the premises for cleaning windows, paints, wallpapers, woodwork, etc. which can be juxtaposed in a room without fear that one of them will be damaged.

Suivant le procédé de l'invention, la dureté importante du matériau constituant la -poudre est compensée par sa faible granulométrie pour obtenir le résultat souhaité, par gommage et non par arrachement des particules du support à nettoyer.  According to the process of the invention, the high hardness of the material constituting the -powder is compensated by its small particle size to obtain the desired result, by scrubbing and not by removing particles from the support to be cleaned.
