The fatigue life of manganese-based phosphated wear-resistant coated steel wire ropes is three to five times that of smooth steel wire ropes. It is very popular among users. In order to prevent the purchase of fake manganese-based phosphated wear-resistant coatings Wire ropes should be distinguished. "Phosphate-coated steel wire rope" is a Chinese invention patent. Its patent number can be searched on the website of the Patent Office of the State Intellectual Property Office and China National Knowledge Infrastructure. There are many domestic companies that have obtained patent authorizations and legally produce manganese-based phosphated wire ropes. The patent number of "phosphate-coated steel wire rope" is sprayed on the packaging wooden shaft of the wear-resistant coated steel wire rope. In addition, the surface of the "phosphate-coated steel wire rope" has a manganese-based phosphating film of 15-40 g/m2, which is also It is called manganese phosphate wear-resistant coated steel wire rope. Therefore, testing the weight of the manganese phosphate film on the surface of the split steel wire is also the most reliable method to determine the authenticity of the manganese phosphate wear-resistant coated steel wire rope. Those with a phosphate coating weight less than 3 grams/square meter are not genuine manganese-based phosphating wear-resistant coated steel wire ropes. Manganese-based phosphating wear-resistant coated steel wire rope is an upgraded product of various smooth steel wire ropes. Smooth steel wire ropes are backward technologies and are also products that are being eliminated.
