DEVICE FOR APPLICATION OF PROTECTIVE COATING ON MECHANICAL RUBBER GOODS Russian patent published in 2000 - IPC

FIELD: application of protective antifriction coating on mechanical rubber goods operating at high temperatures, pressures and speeds, in aggressive media. SUBSTANCE: device has a bath, perforated vessel installed on it, cover for sealing the bath, means for feeding the goods to the vessel and extracting them from it. The device is furnished with heaters for heating the coating material to a temperature of not higher than 47.3 C, means for supply of compressed air with pressure-reducing and distribution valves, refrigerators located on both sides of the bath for concentration of coating vapors. The device is furnished with a means for supply of coating material to the bath is the form of a 2-% solution of fluorine - containing surface-active agents in freon and pipelines for discharge and feed of coating material, compressed air, water, condensate with adjustable valves. Perforation in the vessel is made in the form of cells with an area of 1.0 to 10.0 sq.cm. EFFECT: enhanced safety in use at application of coating, minimized consumption of it, enhanced quality of coating. 1 cl, 1 dwg
