1. natural oxidation
If the use of aluminum alloy material made of the synchronous belt pulley, its surface treatment technology is mostly the use of natural oxidation, natural maintenance mainly refers to the aluminum alloy in the alkaline corrosion electrolysis after the closed color, generally speaking, the depth of the color of the synchronous belt pulley is determined by the thickness of the aluminum film.The purpose of natural oxidation is to increase the corrosion resistance of the belt wheel.
2, the black
The blackening process is also frequently used in the surface treatment of the synchronous belt pulley, which is also a common means of chemical surface treatment. The ultimate purpose is to produce an oxide film on the surface of the belt pulley, mainly to isolate the air, so as to enhance the corrosion resistance of the product.
Synchronous belt wheel surface treatment process is often used in the galvanizing process, the main purpose of galvanizing is the beautiful appearance and rust prevention.The method used in galvanizing is generally hot-dip galvanizing, which can improve the brightness of the belt wheel and increase the attraction of customer purchase.
