China ranks first in the world in terms of annual output of 1.8 million tons of wire rope, and phosphating wire rope is a revolutionary innovation in the field of wire rope in the world, and has entered the era of phosphating coated wire rope in an all-round way:
1. The steel wire is phosphatized by manganese series or zinc-manganese series, and the composite effect of phosphating film and grease makes the steel wire wear-resisting, corrosion-resisting and rust-resisting abilities jump in an all-round way, and its fatigue life is about 3 times that of the smooth steel wire rope with the same structure. The fatigue life can be verified by fatigue test, and the fatigue test done by ourselves is the most credible. It is an upgraded product of smooth steel wire rope, and it can also be used instead of galvanized steel wire rope which is plated first and then thinned with zinc layer. At present, the supply is still tight and the demand exceeds the supply.
2. Galvanized steel wire rope, hot-dip galvanizing and electro-galvanizing
3. Stainless steel wire rope, 34 or 316 stainless steel, which has good anti-corrosion effect but is expensive
4. Plastic coated steel wire rope, based on which the outer layer is coated with polyethylene or polypropylene
5. Smooth steel wire rope will be completely replaced by phosphating coated steel wire rope.
manganese phosphating coated steel wire rope is preferred for atmospheric environment, and hot dip galvanized-phosphating double-coated steel wire rope is preferred for heavy corrosion environment. When purchasing, please indicate the phosphating coated steel wire rope in the invoice, and the patent number should be marked on the outer packaging of the steel wire rope to prevent it from being deceived by the smooth steel wire rope for reference only.
