Manganese phosphating coated elevator wire rope is produced by patented technology, that is, manganese phosphating treatment is carried out on the steel wire for rope making, and a layer of manganese phosphating film is formed on the surface of the steel wire, which can improve the wear resistance and corrosion resistance of the steel wire rope.
The steel gear of automobile gearbox is treated by manganese phosphating film. Through the wear resistance and corrosion resistance of the gear surface, the gear can work normally for more than ten years without wear damage, which shows the effectiveness of manganese phosphating film to improve the wear resistance and corrosion resistance of the matrix.
The fatigue life of manganese phosphating coated elevator wire rope and smooth elevator wire rope can be compared through fatigue test, and the fatigue life can be measured on a fatigue testing machine until the strand breaks, and the fatigue test times are recorded and then compared. The current test data prove that the fatigue life of phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure, and the fatigue life of manganese phosphating coated steel wire rope is the longest. If the company has a fatigue testing machine, please compare and verify it yourself. Larger elevator companies basically have wire rope fatigue testing machines. for reference only
