Plastic coating is good

    Dalian metal plastic coating, plastic spray paint off the paint surface is mainly caused by the lack of adhesion between substrate and paint, effective solution is usually between substrate and paint coating a layer of sun sheng treatment research and development of adhesion treatment, enhance the adhesion between the layers between substrate and paint, get rid of paint phenomenon, through the cell adhesion test for 5 b.


    Plastic forming is easy to form internal stress, stress concentration after coating is easy to crack. The stress can be eliminated by annealing treatment or whole face treatment. Annealing treatment is to heat the ABS plastic parts to the temperature below the thermal deformation, that is, 60℃, insulation for 2h. This process requires a large investment in equipment.
    Therefore, the whole surface treatment technology can be used, that is, the solution can be configured to eliminate the internal stress of the plastic parts, and then the surface of the plastic parts can be treated at room temperature for 15 to 20 minutes. Plastic products are insulators, the surface resistance is in commonly 1013 Ω, prone to static electricity. It is easy to adsorb fine dust in the air and attach to the surface after electrification. Because it is very difficult to remove the dust adsorbed by static electricity by means of general blowing, it is better to use high pressure ionized air flow to remove the dust at the same time.
