Which method to choose for stainless steel surface treatment - Ningxia Jiquan water tank manufacturer answers for you! Welcome to buy Ningxia water tank; Yinchuan water tank and so on!
The common surface treatment technology of stainless steel has the following treatment methods:
1. Whiten the surface color;
2. The surface is polished;
3. Surface coloring treatment.
a. Surface natural color whitening treatment: stainless steel in the processing process, after rolling, binding, welding or artificial surface heat treatment, produce black oxide skin. This kind of hard gray black oxide scale is mainly composed of nicr2o4 and NIF. Previously, hydrofluoric acid and nitric acid were used for strong corrosion removal. However, this method costs a lot, pollutes the environment, is harmful to human body and corrosivity, so it is gradually eliminated. At present, there are two methods to treat oxide scale
Sand blasting (shot) method: mainly uses the method of spraying micro glass beads to remove the black oxide skin on the surface.
Chemical method: use a kind of pollution-free pickling passivation paste and normal temperature non-toxic cleaning solution with inorganic additives. So as to achieve the purpose of whitening the natural color of stainless steel. After treatment, it basically looks like a dull color. This method is suitable for large and complex products.
b. Stainless steel surface mirror polishing method: according to the complexity of stainless steel products and different user requirements, mechanical polishing, chemical polishing, electrochemical polishing and other methods can be used to achieve mirror gloss. The advantages and disadvantages of these three methods are as follows:
c. Surface coloring treatment: Stainless Steel Coloring not only endows stainless steel products with various colors, but also improves wear resistance and corrosion resistance.
Stainless steel has unique strength, high wear resistance, superior corrosion resistance and not easy to rust. Therefore, it is widely used in chemical industry, food machinery, mechanical and electrical industry, environmental protection industry, household appliances industry and home decoration, fine decoration industry, giving people a gorgeous and noble feeling.
The application and development prospect of stainless steel will be more and more extensive, but the application and development of stainless steel largely determines the development degree of its surface treatment technology.
