The post-treatment of galvanized strip steel includes three aspects, passivation, pre-phosphating and oiling. First of all, the galvanized strip steel should be passivated, which can improve the surface structure and luster of the galvanized layer, improve the corrosion resistance and service life of the galvanized layer, and improve the binding force of the coating and the base metal. The passivation treatment is mainly chromate passivation. Some activators, such as fluoride, phosphoric acid or sulfuric acid, are added to the passivation solution to obtain a thicker chromate film after passivation. When there is fluoride in the passivation liquid, 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 to make the passivation film 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 the characteristics of no rust and corrosion resistance for many years, it can be not affected by the external adverse environment, and always maintain its own performance and appearance. In the process of using galvanized strip steel, in order to improve its operation efficiency and its own characteristics, galvanized strip steel products can be post-treated to make its performance better.
