Leading the innovation of spraying, all in automatic spraying machine
The necessity of painting plastic accessories is mainly reflected in the following aspects:
1. **Protective effect**: Painting can protect plastic accessories from erosion by light, rain, dew, water and various media, and prolong the service life.
2. **Decorative effect**: Painting can make plastic accessories have a better appearance, such as brilliance, gloss and smoothness, and enhance the overall beauty of the product.
3. **Special functions**: Through painting, the surface of plastic accessories can have special functions such as fireproof, waterproof and antifouling.
4. **Improving adhesion**: For non-polar plastic materials such as PP, surface treatment is required to improve the adhesion of the paint film. Common surface treatment methods include grinding, flame treatment, chemical treatment agent treatment, etc.
5. **Adaptability**: The painting process is suitable for plastic accessories of various shapes and sizes and has good adaptability.
6. **Environmental protection**: Modern painting processes such as UV light-curing coatings have the characteristics of fast curing speed, high production efficiency and green environmental protection.
7. **Increase product value**: Plastic accessories after painting often have higher value and competitiveness in the market.
8. **Technological progress**: With the development of coating technology, such as the development of low-temperature curing coatings, the painting process of plastic accessories has become more mature and the color difference problem has been improved.
Through these necessities, it can be seen that painting plastic accessories can not only improve the appearance and additional functions of the product, but also enhance its market competitiveness and meet environmental protection requirements.
