摘要
FIELD: process engineering.;SUBSTANCE: invention may be used to increase quality of applying protective, antirust and paint coatings in fluid on steel, concrete or polymer substrate. Proposed method comprises placing substrate and muscle-driven painting unit under water. Said and muscle-driven painting unit comprises acoustic radiator with hydroacoustic shield. Substrate is pre-cleaned of impurities. Substrate surface is subjected to hydroacoustic wave radiation with define acoustic pressure frequency and amplitude. Note here that water is degassed between substrate surface and muscle-driven painting unit working surface and substrate surface is relaxed. Then said and muscle-driven painting unit is sued to apply protective coat. Here, uniform feed of protective composition at pressure is effected on and muscle-driven painting unit working surface. Additional indentation of protective coat into substrate surface is performed at hydroacoustic waves with definite acoustic pressure frequency range. Then, heating and molecular drying at pressure are performed.;EFFECT: higher quality of coating, faster and nonpolluting process.;9 dwg
