The patent technology of phosphating coated wire rope is the most advanced technology in the field of wire rope in the world at present. The fatigue life of manganese phosphating coated steel wire rope is 3-4 times that of smooth steel wire rope with the same structure, which can be verified and compared through fatigue test. At present, there is no wire rope with the same structure whose fatigue life can exceed that of phosphating coated wire rope, so the patented technology of phosphating coated wire rope is the most advanced technology, at least in the field of wire rope in the world at present. Manganese phosphating film can improve the wear resistance and corrosion resistance of steel gear surface of automobile gearbox, and prolong the service life of steel wire rope by using this principle.
Some traditional steel wire rope manufacturers in China think they are well-known brands in the industry, and they are still producing smooth steel wire ropes with traditional technology. It can be said for sure that their technology of producing smooth steel wire rope is backward, and the comprehensive quality of smooth steel wire rope is backward. The service life of smooth steel wire rope cannot be compared with that of manganese phosphating coated steel wire rope at all. The fatigue life comparison test data will tell you which wire rope has longer fatigue life. Many universities, elevator companies and crane companies have wire rope fatigue testing machines. Please do it yourself.
Phosphating coated steel wire rope has longer service life, lower unit use cost, higher stability and reliability, and it is inevitable to win the trust of wire rope users.
With smart phones, does anyone still use them? Does anyone still use a BP machine? Does anyone still use MP3? With flat-screen TV, does anyone still use CRT TV? The times are developing, science and technology are progressing, and enterprises that lag behind the times will be eliminated. Because no wire rope user is a fool, they will choose the wire rope that they are most satisfied with. Whether the enterprise can continue to exist depends on the wire rope users. Those famous brands want to survive, either developing more advanced technology or obtaining patent authorization to produce phosphating coated wire ropes, as long as there are two ways.
