Shijiazhuang spray recruitment

The treatment before plastic spraying is mainly to remove the oil, dust and rust on the surface of the workpiece, and form a "phosphating layer" on the surface of the workpiece that is corrosion-resistant and can increase the adhesion of the sprayed coating. There are two common pretreatment methods: soaking and spraying, and soaking requires multiple soaking tanks; Spraying requires a spraying line.
