1: powder zinc, Our factory is the use of Beijing Nonferrous Metallurgy Design new technology research and development of anti-corrosion, powder galvanizing process, but also known as zinc powder infiltration process, or mechanical galvanizing. It is the use of atomic diffusion and permeation theory, the zinc and steel surfaces in contact with high temperature to form a protective layer of iron and zinc alloy. The performance characteristics: uniform coating, smooth, no zinc residue, Luo appropriation back plated cap, twist comfortable, easy to use, high fastening assembly. Processing range: standard parts, fasteners, electrical fittings, all kinds of complex shape with a cavity or steel parts. Products have been Provincial Quality Supervision, Inspection Institute, have reached the national standard JB5067-91. 
 2: mechanical galvanized, is the glass ball, accelerator, and zinc plated parts together into the octagonal plastic drum, rely on plating and plating, plating and glass friction between the ball and thump, will zinc "cold" to the plating surface, but there are glass balls did not add accelerator, it is not deposited on the plating, zinc plating layer. It can be concluded that in addition to a mechanical zinc plating surface with the physical collision energy, there are chemical enhancers of a supporting role, the plating surface is smooth, uniform and detailed with a certain thickness of the zinc layer. The advantage: due to mechanical galvanizing is a physical method, coating process to avoid the general operation of the hydrogenation plating phenomenon. Was semi-bright coating outside the state, the product is mainly used for export products.
