The necessity of spraying plastic accessories is mainly reflected in the following aspects:
1. * * Enhance Appearance Texture * *: Spraying can change the color, gloss, feel, etc. of plastic accessories, making their appearance more beautiful and improving the overall texture of the product. For example, by spraying, the colors of plastic accessories can be made more diverse, meeting the needs of different designs.
2. * * Improve Durability * *: Spray coating can protect the surface of plastic parts, enhance their wear resistance, corrosion resistance, chemical resistance and other properties, and extend the service life of the product. For example, spraying automotive plastic parts can improve their resistance to ultraviolet radiation, solvents, chemicals, light aging, and other properties.
3. * * Improve surface performance * *: Spraying can improve the surface performance of plastic parts, such as increasing surface hardness, scratch resistance, fingerprint resistance, etc., making them easier to clean and maintain.
4. * * Implement special functions * *: Some spray materials can achieve special functions, such as conductivity, anti-static, antibacterial, etc., to meet specific application needs.
5. * * Improve adhesion * *: For plastic materials such as nylon and PP, due to their high surface crystallinity and low polarity, the adhesion is poor when directly sprayed with paint, making it easy for the paint to peel off. By using specific treatment agents or primers, the adhesion of plastic surfaces can be improved and the problem of paint peeling can be solved.
6. Environmental friendliness: Modern spraying technology tends to use water-based coatings. Compared to traditional solvent based coatings, water-based coatings are more environmentally friendly and have lower VOC (volatile organic compound) emissions, meeting modern environmental requirements.
7. Decorative: Spraying can achieve various decorative effects, such as highlights, matte, metallic effects, etc., increasing the beauty and market competitiveness of the product.
8. * * Protective * *: The spray coating can provide a protective barrier for plastic accessories, protecting them from external environmental damage such as UV rays, chemicals, scratches, etc.
In summary, spraying plastic accessories not only enhances the appearance and texture of products, but also strengthens their functionality and durability, making it an indispensable part of surface treatment for plastic accessories.
