POWDER PAINT COATING DEPOSITION METHOD Russian patent published in 2003 - IPC

FIELD: equipment for plasma spraying used in construction industry, manufacture of metal constructions and road fences and applying markings on covering of roadways. SUBSTANCE: method involves applying powder coating onto article by plasma spraying involving feeding of powder paint into high-temperature gas flow at distance of 50-150 mm from plasmatron nozzle, which is inclined at an angle of 0-60 deg to plasma flow, and polymerizing resultant coating. Plasma-forming gas is air or air mixture and up to 10 wt% of hydrocarbon gases. Polymerization is carried out simultaneously with plasma spraying procedure. EFFECT: increased efficiency and wider range of usage of powder polymeric materials. 3 cl, 1 dwg, 1 tbl
