Stainless steel can be divided into:Ordinary stainless steel T4 1.4401/1.4404
High corrosion MCR 1.4547/1.4529
Note: for passivation of stainless steel and light metal surface
Zinc nickel alloy has ooze coating process introduction (baidu encyclopedia:zinc impregnation powder)
The zinc impregnation agent and steel parts put in infiltration of zinc furnace, heated to a temperature of about 400 , active zinc, nickel atoms is situated to the iron and steel parts penetration. At the same time, the iron atoms by diffusion outside introversion, it's on the surface of steel parts to form zinc nickel and iron intermetallic compound, namely zinc alloy
coating.
Introduction - dacromet coating (baidu encyclopedia: dacromet)
Is given priority to with metal zinc and aluminum, chromium acid and deionized water as solvent scattered high water-soluble coating, coating on metal substrate, after full closed cycle coating baking, form a thin coating, dac romet coatin g resistance to chloride ion erosion successfully, anticorrosion technology has entered a new sta ge, i nnova tion w ith the
defects of traditional process anticorrosion short life.
My company research and development of zinc nickel alloy coating layer + dacromet coating insulation closed in combination with the advantages o f the above co ating, make up for the deficiency of the single coating, ensure that my company's various products under normal atmospheric environment fifty years do not corrode. Many metal composite
coating performance advantages decide its wide application, benefit is remarkable. Such as outdoor steel structure and fasteners, highway guardrail, Bridges, automobile, engineering machinery and other metal parts, powder metallurgy products, as well as chemical, Marine, metallurgical, power genera tion, rail transit and other projects of corrosion resistant, high temperature resistant components can be adopted, the technology will provide the equipment manufacturing industry of our country strong anti-corrosion protection, will certainly to our country such as equipment manufacturing, environmental protection industry made outstanding contributions.
