Phosphating-coated elevator wire rope is a patented technology that uses manganese-based phosphating steel wires to twist elevator wire ropes. The manganese-based phosphating coating can improve the wear resistance and corrosion resistance of the steel wire surface, thereby inhibiting It can prevent fretting wear and oxidation corrosion and greatly extend the fatigue life of elevator wire ropes. It is an upgraded product of smooth elevator wire ropes and complies with the national standard GB8903-2005 elevator wire ropes.
The structural representation method of manganese phosphate coated elevator wire ropes is based on the relevant provisions of the national standard, GB/T8706-2006 terminology marking and classification of wire ropes. This standard has specific provisions, such as 8*19S NF , refers to the Xilu type line contact structure of the steel wire rope composed of 8 strands, each strand composed of 19 steel wires, NF refers to the natural fiber rope core.
