Significance and Effect of Zinc Plating Process
As one of the most commonly used fasteners, U-bolts require long-term protection and maintenance during their use due to the importance of their effects. One of the most important methods for protection and maintenance is to prevent oxidation of U-shaped bolts. This is what we usually call rust prevention. One of the most effective methods is galvanizing. Galvanizing refers to the appearance processing skills of plating a layer of zinc on the surface of metals, alloys, or other materials to achieve beautiful and rust-proof effects. The main method used is hot-dip galvanizing.
The national standard for hot-dip galvanizing is GB / T 13912-2002 "Technical requirements and test methods for hot-dip galvanizing of metal-clad iron and steel parts." Galvanized metals in the future should be lubricated without zinc knobs, burrs, and silver. White; thickness is controllable, deliberately selected within 5-107μm; no hydrogen embrittlement and no temperature hazard on the surface, which can ensure that the mechanical properties of the data are unchanged; it can replace some of the processes that require hot galvanizing; Corrosiveness is good, the neutral salt spray test is up to 240 hours. Galvanized is used in a wide range of applications, such as steel nails, iron nails, fasteners, various hardware fittings, scaffolding fasteners, and so on.
