Product Description

Treatment

The post treatment of galvanized strip includes three aspects: passivation, prephosphating and oiling. First of all, the passivation treatment of galvanized strip steel can improve the surface structure and luster of galvanized layer, improve the corrosion resistance and service life of galvanized layer, and can improve the binding force of coating and matrix metal. Chromate passivation is used in passivation treatment. Some activators, such as fluoride, phosphoric acid or sulfuric acid, are added to the passivation solution to obtain a thick chromate film after passivation. When there is fluoride in the passivation solution, the surface tension of the steel strip can be reduced, the film formation reaction can be accelerated, and the chemical polishing effect can be increased, so that the passivation film is fine and bright.

The application effect of galvanized strip steel is in line with modern needs, and it has been widely used as a building material. Galvanized strip steel has many years of rust, corrosion resistance, it can do not be affected by the outside adverse environment, always maintain their own performance and appearance. In the process of using galvanized strip steel, in order to improve its working efficiency and its own characteristics, galvanized strip steel finished products can be post-treated, so that its performance is more outstanding.
