Automobile plastic parts spray paint

 
	For the coating of Automotive Plastic Parts, the interior part focuses on solvent resistance, and the exterior part focuses on water resistance, abrasion resistance, weather resistance and decoration, etc. Plastic parts can be sprayed manually and automatically.Automobile Parts.Primer spraying,Automobile Spare Parts The wind speed in the manual spraying area of the plastic paint spray booth is generally set at 0.4~0.5m/s, and the process temperature is generally controlled at 18~350°C. In winter, the temperature of the spray booth of this line is generally not lower than 180°C.After the air-conditioning system is transformed into a humidification system, the temperature in summer can basically be controlled below 350°C, and the relative humidity is generally controlled at 60-70%. After the primer plastic paint is sprayed, the wet plastic paint film contains a lot of organic solvents.If it is directly baked in a baking room, the rapid evaporation of the solvent will cause pinholes and bubble defects on the surface of the paint film. During the drying process, as the solvent evaporates, the plastic coating can be fully leveled and spread.dry primer,Car Components. There are two types of plastic paint currently in use, namely quick-drying type and ordinary type.The quick-drying type can be dried naturally, but the ordinary type cannot be cured naturally and quickly after construction, and it needs to be cured by heating. The purpose is to shorten the drying time and improve the coating performance.At the same time, considering the heat resistance and easy deformation characteristics of plastic parts, the drying temperature should not be too high.
