Patent of coating tools

In the past, only smooth steel wire ropes were used. The fatigue life of manganese phosphating wear-resistant coated steel wire ropes is 3-5 times that of smooth steel wire ropes, which is an upgraded product of various smooth steel wire ropes. In order to prevent buying fake manganese phosphating wear-resistant coated steel wire rope, we should learn the method of distinguishing authenticity. "Phosphating steel wire rope" is an invention patent of China. The patent number of "phosphating wire rope" can be found on the website of China National Intellectual Property Administration Patent Office and China Knowledge Network. Many domestic enterprises have obtained patent licenses to produce manganese phosphate coated steel wire ropes, and the wooden shafts are coated with patent numbers. In addition, the weight of phosphating film must be checked after the arrival of manganese phosphating wear-resistant coated steel wire rope, which should comply with the contract agreement with the manufacturer, generally at 15-40g/m2, which is an effective method to ensure the quality of manganese phosphating wear-resistant coated steel wire rope.
