Nylon coated wire rope is referred to as coated wire rope. The wire rope is coated. The nylon coated film makes the surface of the steel wire more wear-resistant and improves its anti-corrosion ability. The porous structure of the nylon coated film can increase the storage of grease on the surface of the wire rope. It reduces the friction factor and promotes sliding, delays the occurrence of fretting damage on the surface of the steel wire, inhibits the initiation of fatigue microcracks, thereby greatly prolonging the service life of the wire rope. nylon coated wire rope is a technology in the field of wire rope that uses surface treatment measures to suppress fretting fatigue means.

Nylon coated wire rope technology is mainly used for anti-rusting of steel materials, reducing friction during cold working, improving wear resistance, bonding intermediate phases, electrical insulation and surface decoration, etc. Among them, the coating treatment process whose main function is to improve the wear resistance of steel materials, reduce friction, and improve lubrication is widely used in frictional motion bearing parts in the fields of automobiles, light industry, chemical industry, electrical appliances, and national defense. The nylon coated wire rope technology is applied to the wear resistance, friction reduction and rust prevention of the steel wire in the steel wire rope. The combined effect of the phosphate film and the grease on the surface of the steel wire is far better than any single grease.

Abrasion is the most common damage method of steel wire rope, which is generally divided into three situations: external wear, deformation wear and internal wear. For wire rope products, in order to prolong the service life of the wire rope, when the fretting between the wires cannot be eliminated, technical measures can only be taken to prevent the wear caused by the fretting [4]. Fretting fatigue damage is closely related to the surface properties of the material. The use of surface engineering technology can improve the anti-fretting fatigue performance of traditional materials and enhance the fretting fatigue resistance of new materials; the use of surface modification methods can effectively improve the anti-fretting damage performance of the material, increase the wear resistance, and improve the resistance to micro-motion Dynamic damage performance. Taking these surface protection measures will help weaken or block the damage caused by the frictional force during the relative sliding between the steel wires, thereby inhibiting and delaying the occurrence of fretting damage on the steel wire surface, and greatly extending the service life of the steel wire rope.

The nylon coated film itself has good electrical insulation, which can effectively inhibit the formation of micro-batteries on the surface of the nylon coated wire rope; the combined effect of the phosphate film and the grease can greatly improve the lubrication effect between the nylon coated wire ropes and the nylon coated Corrosion and oxidation resistance of wire rope. Nylon coated wire rope is the phosphating treatment of the rope-making steel wire and the film weight is controlled between 3g/m2-60g/m2, including carbon steel wire, alloy steel wire, galvanized steel wire, aluminum-plated steel wire, zinc-aluminum alloy coated steel wire, etc.
