Abstract

The invention relates to a steel wire rope plastic coating technology. The technology comprises the following steps: (1) processing the surface of a steel wire before plastic coating; (2) dipping a plastic liquid, the plastic liquid being a mixed acid solution in which polytetrafluoroethylene solid content is 10-20 wt%; (3) and processing after plastic coating. A plastic-coated steel wire rope manufactured by the plastic coating technology is good in anticorrosion performance, and has good lubricating property and low friction coefficient.

Description

technical field [0001] The invention relates to a steel wire rope processing technology, in particular to a steel wire rope plastic coating technology. Background technique [0002] The steel wire rope is a flexible rope twisted with multiple or multiple thin steel wires. The steel wire rope is twisted into strands by multi-layer steel wires, and then centered on the rope core, a certain number of strands are twisted into a helical rope. Steel wire ropes can be classified by shape, layer, state, etc. According to the shape, it can be divided into round strand steel wire rope, braided steel wire rope and flat steel wire rope; steel wire rope can be divided into single winding rope, double winding rope and triple winding rope according to the level of winding; steel wire rope can also be divided according to the contact state between each layer of steel wire in the strand There are 3 types of point contact, line contact or surface contact. In material handling machinery, it ...
