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 elevator wire rope is 3-4 times that of smooth elevator wire rope with the same structure, up to 5 times, 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.
Smooth elevator wire ropes are being eliminated. With a smart phone, does anyone still use a mobile phone the size of a brick? Does anyone still use a BP machine? Does anyone still listen to music on 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. For wire rope users, just buy manganese phosphating coated wire rope, which has longer service life, lower use cost and higher stability and reliability. Why not? Personal opinion, for reference only.
