Title
(EN) APPLICATOR FOR SHEAR THINNING VISCOUS COATING MATERIALS
(FR) APPLICATEUR POUR FLUIDIFIER DES MATERIAUX DE REVETEMENT VISQUEUX
Abstract
(EN)
A pneumatic applicator (10) for shear thinning viscous coating materials that includes a nozzle, an air operated system for dispensing viscous material at a steady rate through the nozzle (11), and an air directing housing (22) defining an air chamber (23) around the nozzle (11). The air directing housing (22) defines an air outlet opening (26) for the air chamber (23) around the nozzle (11). Distal surfaces of the housing (22) and nozzle (11) are close to coplanar and the air outlet opening (26) has an area in the range of about 5 to 15 square millimeters. An adjustable system directs air under pressure into the air chamber (23) so that when the viscous material is disposed through the nozzle (11) at a generally uniform rate, air can be directed into the chamber (23) and out through the air outlet opening (26) around the nozzle and only the amount of air being directed into the chamber (23) need be adjusted to cause viscous material being dispensed from the nozzle (11) to be applied to a surface adjacent the nozzle (11) in coatings of various widths and thicknesses.
(FR)
Applicateur pneumatique (10) pour fluidifier des matériaux de revêtement visqueux comprenant une buse, un système à air comprimé pour distribuer à une vitesse constante un matériau de revêtement visqueux via la buse (11) et un corps pour régler la direction de l'air (22) formant chambre d'air (23) autour de la buse (11). Le corps servant à diriger l'air (22) définit un orifice de sortie d'air (26) dans la chambre d'air (23) autour de la buse (11). Les surfaces distales du corps (22) et de la buse (11) sont pratiquement dans le même plan et l'orifice de sortie d'air (26) a une surface comprise entre environ 5 et 15 mm2. Un système réglable dirige l'air sour pression dans la chambre d'air (23), de telle sorte que lorsque le matériau visqueux est déchargé via la buse (11) à une vitesse généralement uniforme, l'air peut être dirigé dans la chambre (23) et au dehors à travers l'orifice de sortie d'air (26) se trouvant autour de la buse, et il suffit de régler la quantité d'air dirigée dans la chambre (23) pour que le matériau visqueux distribué par la buse (11) soit appliqué sur une surface adjacente à celle-ci sous la forme de revêtements de diverses largeurs et épaisseurs.
