Galvanizing and anti-corrosion technology is a technology to infiltrate zinc and aluminum elements into the surface of steel components to form a protective layer to achieve anti-corrosion purposes. The use of zinc as a protective coating material is currently the most widely used process. The nano-composite powder zincizing process adopts a new and improved zincizing mixture to obtain a more effective zinc/iron (Zn/Fe) alloy coating. The advantages of this new process are: good coating thickness uniformity; high hardness, wear resistance and good scratch resistance; the powder zincizing layer Zn/Fe alloy is the hardest among all zinc coatings; and the matrix With high bonding strength, the powdered zincification layer is diffusion metallurgical and can only be removed by chemical methods. The corrosion resistance is strong, and the test shows that the corrosion resistance of the coating is higher in a variety of environments such as the marine atmosphere and the harsh industrial atmosphere. Electro-galvanized, 10%～30% higher corrosion resistance than hot-dip galvanizing; good coating performance, high adhesion strength between powdered zincizing layer and various paints and polymer coatings; low temperature of sherardizing, no The mechanical properties of the components are affected, there is no hydrogen embrittlement phenomenon; the process does not have "three wastes" emissions, and is a green cleaning technology.
Compared with the traditional zincification process, the nano-composite powder zincizing process can increase the corrosion resistance by 10% to 20%, increase the surface hardness by more than 10%, and increase the wear resistance and scratch resistance; the processing time is shortened by 1 hour. Increased production efficiency.
According to statistics, the total cost of the country's corrosion protection market is estimated to reach 500 billion yuan each year, accounting for about 5% of the national economic output value. Among them, the total market output value of metal surface treatment is estimated to be more than 500 billion yuan per year, and the short-term direct market gross output value of powdered zinc surface treatment can reach more than 20 billion yuan.
