Title (EN) PROCESS AND DEVICE FOR CLEANING AND KEEPING THE CLEANLINESS OF SURFACES
(FR) PROCEDE ET DISPOSITIF POUR LE NETTOYAGE ET LE MAINTIEN DE LA PROPRETE DE SURFACES
Abstract: front page image
(EN)Process and device for cleaning and keeping the cleanliness of surfaces (1) either vertical or sloped exposed to heavy fouling. At the upper edge of the surface to be cleaned a cleaning fluid of low volatility, and foam controlled, having cleaning properties is applied in a thin film by means of a nozzle, in particular a nozzle with fluidic oscillations (4) which does not have moving parts. This film flows continuously without interruption towards the bottom with a high turbulence forming waves (7) at short intervals, influencing significantly the cleaning of the surface. According to the invention one of the best cleaning fluids is constitued by 10% of surface active derivate, 45% of ethylglycol, 15% of polyethylglycol, 3% of dryer-polisher and 0.5% of a bactericide. A cleaning device for windows can be entirely integrated in the spaces (25, 29) of a metal or plastic window frame (20).
(FR)Procede et dispositif pour le nettoyage et le maintien de la proprete de surfaces (1) verticales ou inclinees exposees a de forts encrassements. Au bord superieur de la surface a nettoyer un liquide de nettoyage peu volatil, a mousse controlee, presentant des proprietes lavantes, est applique en un film mince au moyen d"une buse, notamment d"une buse a oscillations fluidiques (4) qui n"a pas de partie mobile. Ce film s"ecoule d"une maniere continue sans interruption vers le bas avec une haute turbulence provoquant des ondes (7) rapprochees influencant de facon decisive le nettoyage de la surface. D"apres cette invention l"un des meilleurs liquides nettoyants se compose de 10% de derive tensio-actif 45% d"ethylglycol, 15% de polyethylglycol, 3% de seche-brille et 0,5% d"un bactericide. Un dispositif de nettoyage pour fenetre peut etre integre entierement dans les vides (25, 29) d"un cadre de fenetre (20) en metal ou en matiere plastique.
