The thicker the manganese phosphating wear-resistant protective coating of elevator wire rope, the longer the service life?

The thicker the manganese phosphating film on the surface of steel wire, the stronger the wear resistance and corrosion resistance of steel wire rope, which can improve the service life. The weight of manganese phosphating film is between 3 and 60 g/m2, and the larger the film, the better. The weight range of manganese phosphating film can be determined through consultation with the manufacturer and written into the contract.

The fatigue life of smooth elevator wire rope is only 600 thousand times, and only the fatigue life of elevator wire rope coated with manganese phosphating can reach 2 million times. Manganese phosphating film is a kind of wear-resistant protective coating, which can greatly improve the wear resistance and corrosion resistance of steel wire surface, thus greatly improving its service life. Phosphating coated steel wire rope is an invention patent in China, and the patentee is a natural person. Any enterprise that wants to produce manganese phosphating coated steel wire rope needs to obtain patent license before it can be legally produced. The fatigue life of manganese phosphating coated elevator wire rope is 2 million times, which is much higher than 600 thousand times of smooth elevator wire rope. Of course, it is really high quality and long life. Smooth elevator wire rope is an outdated product and is being eliminated.
