What are the functions of surface oil spraying on aluminum alloy shells

 

Firstly, spraying oil on the surface of the aluminum alloy shell can play a role in preventing corrosion. Aluminum casings may be eroded by various chemical substances and environmental factors during the production process, leading to corrosion. The sprayed oil film can isolate air, moisture and various chemical substances, playing a protective role.

Secondly, spraying oil on the surface of the aluminum shell can improve the appearance quality. After the surface of aluminum alloy is treated with oil spraying, a smooth and uniform coating can be formed, making the surface of the aluminum alloy look brighter and more beautiful, and enhancing its visual effect.

 

Secondly, spraying oil on the aluminum alloy shell can play a role in wear resistance and scratch resistance. The specially treated oil film can enhance the surface hardness of the aluminum alloy shell, reduce scratches and wear. This not only prolongs the service life of the shell.

In addition, the oil spraying on the aluminum shell can also play an insulating and anti-static role. Some aluminum alloy casings need to have insulating properties to prevent the accumulation of static electricity and the generation of electric sparks. In some cases, aluminum alloy needs to come into contact with other substances to conduct electricity. However, in some special circumstances, aluminum alloy needs to remain in an insulating state to prevent accidents such as short circuits. The sprayed oil film can effectively isolate the current and potential difference, ensuring the insulation performance of the casing.

 

In conclusion, the main functions of oil spraying on aluminum casings are to protect aluminum alloys, enhance appearance quality, prevent slipping and wear, and maintain insulation performance. Surface painting is an indispensable process in the production of aluminum alloy shells. It can play multiple roles such as anti-corrosion, wear resistance, scratch resistance, insulation, anti-static and improving waterproof performance, thereby extending the service life of the aluminum alloy shell, enhancing the quality and aesthetic appearance of the product.
