Painting line used in construction is very good, he usually adopts electrostatic spraying on the workpiece spraying equipment mainly composed of spraying room by spraying room, electrostatic spraying equipment and spraying, powder recovery device etc.. The water screen spray room is simple and practical,Powder coating equipment is widely used in the painting in the painting line.

As the curtain curtain spray booth front plate, curtain plate above the overflow tank, coating environmental protection equipment in the construction process, the workpiece by the suspension conveyor chain into the spray chamber. The operator with a hand-held electrostatic spray gun or a fixed rotary cup of spray gun on the workpiece during spraying operations, a spray paint mist with air attract flying painting room, and the curtain curtain board, first met, was washed into the water tank, the remaining paint mist in water purified by multistage spray, completely blocked in the water.

Go to the air after the paint mist gas water separation device, remove odor treatment, gas purification after the last foreign emissions. The curtain caught the paint mist with the water poured in the water pool, the water pump suction filter, paint residue floating on the water, in the pool in the paint coagulant function, condensed into a loose mass, can scoop out the container centralized processing, to keep the water clean. Through the water screen spray room and auxiliary equipment, can be the ideal completion of the work of the paint and paint mist purifying.

In the electrical explosion prevention (fire), there are also many shortcomings, such as: electrical explosion (fire) level does not meet the national mandatory standards requirements, explosion-proof (fire) facilities are not complete and so on. Because of these problems will not affect the quality of spraying the workpiece, so often neglected or from cost considerations to be cut, so need to supervise the relevant departments and mandatory requirements to promote, to eliminate security risks, improve the working environment of the operator, and the exhaust gas (water) emission standards, environmental protection coatings have developed rapidly and played a positive role in reducing environmental pollution.
