What is the role of Zinc Fume Enclosure surface pretreatment?

In the process of producing the chassis, the surface pretreatment of the chassis is an indispensable part. So what do you know about the surface pretreatment of the Zinc Fume Enclosure ？ Let me share with you the role of the surface pretreatment of the chassis.

First, prepare for the final surface treatment

In fact, in the final analysis, the purpose of surface pre-treatment of the chassis is to lay the foundation and preparation for the final surface treatment. Only the pre-treated Zinc Fume Enclosure  can be transported to the next node of the product line. For example, if the surface of the chassis is to be sprayed during processing, the pretreatment can help the coating and the surface of the chassis to blend together more perfectly and effectively.

Second, clean the surface of the chassis

There are many things that need to be done in the pre-treatment of the surface of the chassis. The first step is to clean all kinds of foreign objects on the surface of the chassis, including some stains, dust, rust, oil, etc., to make the next coating. Bottom."

Third, leveling the surface roughness of the chassis

After cleaning the surface of the chassis, it is necessary to evenly apply a pre-prepared coating film that can protect the surface of the chassis, such as corrosion resistance, oxidation resistance, and good decorative effects. However, the basis for the best effect of the coating film is the cleaning work of the previous step. Only the surface of the chassis is cleaned, and the coating can have a good substrate to achieve a more perfect effect.

The role of pretreatment of the Zinc Fume Enclosure  surface can not be ignored, although the pre-processing steps and methods do not seem difficult, but it is still difficult to really do it.
