New anti-corrosion technology of electric hoist wire rope

2018-06-26
Electric Winch is a small lifting equipment, suitable for construction, shopping malls, power, workshops, warehouses, factories and other industries, easy to use, cost-effective. However, the use of a hoist for a long time will inevitably result in the wear of the steel wire rope. Therefore, in order to increase the service life of the equipment, the steel wire rope needs to be subjected to anti-corrosion treatment. The details are as follows.
1. Oil rope anti-corrosion method:
All wire ropes must be oiled. The impregnation of the fiber core requires the grease to protect the fiber core from rot, corrosion of the steel wire, moisturize the fibers, and lubricate the wire rope from the inside. The surface oiling uniformly spreads a layer of rust-proof lubricating grease on all steel wire surfaces in the strands. For the mine shafts with high friction and high mineral water, black oil grease with increased grinding and strong water resistance should be applied. It is coated with red oil grease with strong film-forming and rust-preventing properties, and requires thin oil layer to keep it clean during operation.
2. Wire rope coating anti-corrosion method:

Coatings are galvanized, aluminized, coated nylon or plastic. The galvanized steel wire is divided into a thin plating layer which is first plated and then pulled out, and a thick plating layer which is galvanized after pulling out the steel wire. The mechanical properties of the thick plating layer are lower than those of the smooth steel wire rope and should be used in a severe corrosive environment. Aluminized steel wire rope is more corrosion-resistant, wear-resistant and heat-resistant than galvanized steel wire rope. It is mainly used for fishing trawl ships and mines containing H2S, etc. It is produced by plating and then drawing. Nylon or plastic coated wire ropes are used to coat ropes and coat strands. The former is used for static cables and the latter is used for moving cables.
