Users who have used steel wire know that rust and wear are the main cause of Steel Wire damage failure. The previous method to prevent steel wire rusting is to oil the steel wire. Since the grease cannot penetrate into the steel wire, sometimes the wire rope starts to rust from the steel wire.
Phosphated coated steel wire rope is a patented technology that has appeared in recent years. The use of phosphating steel wire directly to twist the steel wire rope, the phosphate coating can greatly improve the wear resistance and corrosion resistance of the steel wire surface, thereby inhibiting the occurrence of fretting fatigue. Extended service life. The phosphating coating is non-conductive, so that the surface of the steel wire cannot form a micro-battery, thereby suppressing the occurrence of electrochemical corrosion and preventing the steel wire rope from rusting. Manganese-based phosphating coatings and zinc-manganese phosphating coatings have very good wear resistance and corrosion resistance, preventing the occurrence of steel corrosion.
The current fatigue test data proves that the fatigue life of the phosphate coated steel wire rope is 3-4 times that of the structural smooth steel wire rope. The longer the fatigue life, the longer the service life is. It is the leading technology in the world wire rope industry. The fatigue life of different types of steel wire ropes can be determined by fatigue test on a fatigue tester and compared, and the steel wire rope with the longest fatigue life can be screened. At present, there is no wire rope that can surpass the phosphating coated wire rope, that is, the phosphate coated steel wire rope. The fatigue life is the longest, and the smooth steel wire rope is being completely eliminated. For all kinds of lifting machinery, the use of the phosphating coated steel wire rope should be preferred in the atmospheric environment.
