Zinc alloy handles, as a kind of common metal handles, are widely used because of their excellent performance and beautiful appearance. Polishing is an important link in the processing of zinc alloy handles, which is of great significance to improve the surface quality and prolong the service life of handles. In this paper, we will discuss the polishing process of zinc alloy handles, analyze the characteristics and scope of application of different polishing methods, in order to provide reference for the polishing of zinc alloy handles.
1. improve surface quality: polishing can remove burrs, scratches and other defects on the surface of zinc alloy handles, so that the surface of the handles is more smooth and beautiful.
2. enhance corrosion resistance: polishing can eliminate the tiny holes on the surface of zinc alloy, reduce the penetration of corrosive media, and improve the corrosion resistance of the handles.
3. prolong service life: after polishing zinc alloy handles, the surface is smooth, not easy to adhere to the dirt, easy to clean and maintain, thus prolonging the service life.
4. Improve the added value of the product: polished zinc alloy handles have a higher degree of aesthetics, which can improve the market competitiveness of the product and increase the added value.
1. manual polishing: manual polishing is suitable for small batch, complex shape zinc alloy handles. Simple operation, high flexibility, but lower efficiency and greater labor intensity.
2. mechanical polishing: mechanical polishing is suitable for large quantities of zinc alloy handles with regular shape. Higher efficiency, stable quality, but the equipment investment is larger. 3.
3. chemical polishing: chemical polishing is suitable for zinc alloy handles with high surface requirements. The composition of polishing liquid can be adjusted according to the need, and it is suitable for different types of zinc alloy. However, chemical polishing has a certain degree of pollution to the environment, need to strengthen the protective measures. 4.
4. Electrochemical polishing: Electrochemical polishing is suitable for zinc alloy handles requiring very high surface quality. During the polishing process, the surface metal is removed by electric current control to achieve a high degree of polishing. However, the equipment cost is high and the operation is complicated.
5. laser polishing: laser polishing is suitable for high-precision, high-demand zinc alloy handles. Utilizing the high energy of the laser to instantly act on the surface of the material to remove small defects. Polishing speed, high quality, but expensive equipment.
In the choice of zinc alloy hand polishing process, should be based on product batch, shape, surface quality requirements and other factors for comprehensive consideration. For small quantities, complex shape of the handles, can choose manual polishing; for large quantities, regular shape of the handles, can choose mechanical polishing; for high-precision, high requirements of the handles, can choose electrochemical polishing or laser polishing. At the same time, for different polishing methods, should take appropriate protective measures to ensure polishing quality and production safety.
Conclusion: The polishing process of zinc alloy handles is of great significance to improve product performance and aesthetics. Through the discussion of different polishing methods, it can provide reference for the polishing process of zinc alloy handles. In the actual production process, the appropriate polishing process should be selected according to the product characteristics and needs to achieve high-quality and efficient production of zinc alloy handles. At the same time, the environmental protection and occupational health management in the polishing process should be strengthened to improve the green level of production.
