Galvanized strip steel is cold rolled or hot rolled, long and narrow strip steel plate on different levels of plating layer is called (
Zinc, aluminum)
The raw material.
Hot dip galvanized with uniform coating, strong adhesion, long service life, etc.
Hot dip galvanized strip steel substrate with molten electrolyte solution in complex physical and chemical reaction, the formation of corrosion resistance of the structure compact zinc alloy layer.
Pure zinc alloy layer and layer and steel substrate.
So the corrosion resistant ability.
Galvanized steel strip post-processing includes three aspects, passivation, phosphating and oil.
First to passivation treatment of galvanized steel strip, can improve gloss, the surface of the galvanized layer structure and improve the corrosion resistance and service life of the galvanized layer, and can improve the adhesion strength of the coating and base metal.
The passivation treatment mainly adopts chromate passivation.
Adding activator in the passivation solution, such as fluoride, phosphate or sulfate, make get thicker chromate film after passivation.
When in the passivation solution fluoride can reduce steel strip surface tension, film forming reactions, and can increase the chemical polishing effect, the passivation film light.
Galvanized steel strip application effect is in line with modern requirements, in today have been widely used as building materials.
Galvanized steel strip has the characteristics of many years does not rust, corrosion resistance, it can be done is not affected by outside bad environment, keep their own performance and appearance.
In the process of using galvanized steel strip, in order to improve the operational efficiency and their features, the galvanized strip steel finished product can be reprocessing, make its performance better.
