Advantages of mechanical galvanizing

· Galvanized Car Transport Trailer

1. Compared with electrogalvanizing In industrial applications, the electrogalvanizing process will precipitate hydrogen on the cathode, which will cause hydrogen permeation on materials such as high-strength steel, resulting in hydrogen embrittlement and fracture of high-strength steel parts during use, thus causing serious accidents, which have occurred from time to time at home and abroad. Mechanical galvanizing does not cause hydrogen embrittlement to high-strength steel parts, and this functional advantage is incomparable to electrogalvanizing. In addition, mechanical galvanizing is simple to operate, and the roller plating of small parts is easier to control, with low energy consumption and fast plating speed. A 50um thick coating can be completed in 0.5h, with high production efficiency.

2. Compared with hot-dip galvanizing Hot-dip galvanizing is mostly used on large steel parts as a long-term outdoor protective coating, but standard fasteners used outdoors are basically operated manually.

In addition to the characteristics and requirements of the hot-dip galvanizing process, it is more convenient to use mechanical galvanizing. In addition, when hot-dip galvanizing small parts such as gaskets, the parts are easy to stick together; when plating threaded parts, the molten zinc will block the threads; when plating nuts, they must be re-threaded after plating; and hot-dip galvanizing is an energy-consuming process that requires high-temperature operation, harsh environment, and serious environmental pollution.

Functionally, hot-dip galvanizing with high temperature melting will cause annealing and softening of the surface of quenched high-strength steel fasteners, affecting the quality of the plated parts and changing the original performance, thus becoming unqualified products.

The mechanical galvanizing layer also has the function of resisting atmospheric acid rain. Through experimental comparison, its acid rain resistance is three times that of hot-dip galvanizing, and this characteristic is also very outstanding.
