Oil brush patent

Users buy wire ropes, of course, hoping that the longer the service life of wire ropes, the better, and the lower the average daily use cost. Manganese phosphating film on steel wire surface is a kind of wear-resistant protective coating and a common surface treatment method for steel mechanical parts. The greater the weight of phosphating film, the stronger the wear resistance and corrosion resistance of steel wire surface. The phosphating film of 30g/m2 is more wear-resistant and has a longer service life than that of 15g/m2. When purchasing manganese phosphating wear-resistant coated steel wire rope, we must pay attention to the small phosphating film, which is an extremely important technical index. Many domestic enterprises have obtained patent authorization. When purchasing manganese phosphating wear-resistant coated steel wire rope, the thickness of wear-resistant coating can be agreed with the manufacturer. Smooth steel wire rope has no wear-resistant protective coating, and its service life is far less than that of manganese phosphating wear-resistant coated steel wire rope. Smooth steel wire rope has short service life and high unit use cost, which belongs to obsolete products.
