According to the painting production process, painting exhaust gas mainly comes from pre-treatment, spraying, and drying processes. 

Usually, metal surfaces are covered with dust, oil stains, oxide scales, rust layers, pollutants, salt content, or loose old paint films. The success of painting mainly depends on the quality of surface treatment. If these substances are not removed and directly applied, it will inevitably affect the adhesion and anti-corrosion ability of the entire coating.

Dalian metal plastic coating is heated and melted. For wire, when the end enters the high-temperature area of the heat source, it is heated and melted; For powders, they enter the high-temperature area of the heat source and are heated, melted, or softened during their movement. During the jet flight of melted or softened fine particles, the particles are first accelerated to form a particle flow, and as the flight distance increases, the particle velocity gradually decreases.

At present, Dalian Metal Plastic Coating mainly uses spray free plastics such as spray free PP, spray free ABS, spray free PC, spray free PC/ABS, spray free AS, etc. Its application fields cover household appliances, electronic appliances, automobiles, 3C fields, rice cookers, washing machines, air conditioning panels, mobile phone cases, automotive accessories, etc.

Dalian metal and plastic spray painting knowledge, metal surface spray painting is a method to protect metals from oxidation and corrosion. 

In the metal surface coating process, the firm adhesion of the paint film to the substrate can play a role in protection, decoration, and corrosion prevention. The firm adhesion of paint film on metal surface is closely related to the roughness, thermal expansion and contraction coefficients of the coated substrate surface. Generally speaking, when the surface is too smooth or the temperature coefficient of change between the paint film and the substrate is significantly different, the adhesion of the paint film will deteriorate, and it is common for the paint to peel off from the metal substrate.
