Fretting wear, fatigue and rust are the causes of damage and failure of traction elevator wire ropes. Suppressing fretting wear and rust can extend the service life of elevator wire ropes. The manganese phosphate coating is a wear-resistant protective coating that can prevent fretting wear and has strong anti-corrosion capabilities. The fatigue life of the manganese phosphate wear-resistant coating elevator wire rope is three to five times that of the smooth elevator wire rope. The wear resistance of the manganese phosphate film is related to the film weight and properties of the phosphate film. Generally, the weight of the film is greater than 15 grams/square meter. Pay attention to this technical indicator when purchasing. Please note that phosphate-coated steel wire rope is a Chinese invention patent. Only companies that have obtained patent licenses can legally produce it. Patent infringement will face huge financial claims.
