Construction technology of boiler thermal spraying

       Main points of boiler spraying process: check and verify materials; check whether the air compressor, sprayer, water pump and other equipment are normal; check whether the conveying pipeline is in good condition and smooth; check whether the angle of the spray gun is correct, and whether the water pressure and wind pressure are adjusted according to the actual situation on site; The air compressor, sprayer, water pump and other equipment are normal. The pipeline is intact and smooth.



Quality requirements: The material model is correct, the physical and chemical performance indicators meet the design requirements; the spray gun angle is correct, the water pressure and air pressure and other parameters are suitable, the mixing is uniform and continuous during spraying, and there is no spraying defect such as dry material or flow.



Spray paint inspection Check the tightness of the spray paint. The spraying is dense, without delamination, holes and other defects.
