The necessity of spraying plastic parts is mainly reflected in the following aspects:
1. Improve adhesion: plastic parts in the coating, surface treatment must be carried out to improve the adhesion of the plastic coating, reduce the defects on the surface of the paint film. Due to the smooth surface of the plastic parts, poor wettability, direct spraying will result in poor adhesion of the paint film to the substrate, through the surface treatment can improve this problem.
2. Enhance the appearance and texture of the product: the surface treatment of plastic parts can enhance the appearance and texture of the product, to achieve a diverse range of decorative effects, such as frosted, polished, coated and so on.
3. Enhance weathering and abrasion resistance: surface treatment of plastic parts can improve its abrasion resistance and weathering resistance, and extend the service life of the product. 6.
4. anti-corrosion treatment: plastic parts spray coating can improve its surface hardness and abrasion resistance, and at the same time play a role in anti-corrosion, especially for equipment and steel structure and its components surface anti-corrosion treatment.
5. Meet the needs of industrial applications: surface treatment of plastic parts plays a vital role in modern manufacturing industry, through the surface treatment, can meet the needs of different industrial applications. 8.
6. Environmental protection and energy saving: compared with the traditional metal coating, plastic coating process has fewer steps and saves more energy, and the plastic itself does not rust.
In summary, plastic parts coating can not only enhance the appearance and texture of the product, but also enhance its functionality and durability, is an indispensable process step in modern manufacturing.
