Zinc plating refers to a surface treatment technique that coats a layer of zinc on the surface of a metal, alloy or other material for aesthetics, rust prevention, and the like. The main method used is hot-dip galvanizing.
Main feature
1. The appearance is smooth, no zinc, burr, silver white;
2. The thickness is controllable, arbitrarily selected within 5-107μm;
3. No hydrogen embrittlement, no temperature hazard, can ensure the mechanical properties of the material unchanged;
4. It can replace some processes that require hot-dip galvanizing;
5. Good corrosion resistance, neutral salt spray test for 240 hours.
Application range Steel nails, nails, fasteners, water pipe joints, scaffolding fasteners, wire rope horse steel chucks, etc.
Electro-galvanizing are more and more extensive. The application of fastener products has been of great significance in the national economy throughout the manufacture of machinery, the manufacture of galvanized hook-and-click chains, electronics, precision instruments, chemicals, transportation, and aerospace.
Hot-dip galvanizing is especially suitable for strong corrosive environments such as strong acid and alkali mist.
