At present, the most effective method to solve the wear of traction elevator wire rope is manganese phosphating coating. Phosphating coated steel wire rope is a patented product. The surface of rope-making steel wire is treated with manganese or zinc-manganese wear-resistant phosphating coating, and the steel wire rope is directly twisted with phosphating steel wire (without wire drawing after phosphating). Manganese series or zinc-manganese series phosphating is a wear-resistant phosphating film, which can greatly improve the wear resistance and corrosion resistance of wire rope surface. The surface of steel gear of automobile gearbox is treated with manganese phosphating wear-resistant coating, which can ensure the gear to work normally at high speed and heavy load for more than ten years. It can be seen that manganese phosphating film is very effective to improve the wear resistance of steel. Manganese phosphating coated steel wire rope also uses the above principle to extend its service life.
Manganese phosphating coated steel wire rope fully meets the technical indexes of current national standards and industry standards, and can be purchased and used with confidence. Manganese phosphating coated wire rope is the most advanced technology in the wire rope industry in the world at present, because it has the longest fatigue life and is also the most wear-resistant wire rope product. The phosphating film weight of several domestic manganese phosphating coated wire ropes is generally in the range of 15-30g/m2, which is the technical index that must be paid attention to when purchasing manganese phosphating coated wire ropes. Manganese phosphating wear-resistant coated steel wire rope has longer service life and lower unit use cost.
