Ultrahigh-molecular-weight polyethylene fiber cable

Abstract

The invention discloses an ultrahigh-molecular-weight polyethylene fiber cable which comprises a cable body. An anticorrosion coating is arranged outside the cable body, a waterproof layer is arrangedinside the anti-corrosion coating and positioned on the inner side of the same, a first cable strand, a second cable strand, a third cable strand and a fourth cable strand are arranged inside the cable body symmetrically, and a core sleeve is arranged in the middle of the first cable strand, the second cable strand, the third cable strand and the fourth cable strand. The cable is formed by twisting the four cable strands, so that the cable is smaller in size and easy to store under equivalent strength; twisting direction of polyethylene fiber inside the first cable strand and the third cablestrand is leftwards while that of the polyethylene fiber inside the second cable strand and the fourth cable strand is rightwards, so that the problem of autorotation of the cable can be eliminated effectively, and the cable is high in practicability.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an ultra-high molecular weight polyethylene fiber cable. Background technique [0002] The English name of ultra-high molecular weight polyethylene is ultra-high molecular weight polyethylene (UHMWPE for short), which is an unbranched linear polyethylene with a molecular weight of more than 1.5 million. Molecular formula: —(—CH2-CH2—)—n—, density: 0.920~0.964g / cm3. The heat distortion temperature (0.46MPa) is 85°C, and the melting point is 130-136°C. Ultra-high molecular weight polyethylene is a kind of polymer compound, which is difficult to process, and has super wear resistance, self-lubrication, high strength, chemical It has stable properties and strong anti-aging performance. In the prior art, high-molecular-weight polyethylene fibers are rarely used to make cables. At the same time, ordinary cables have the problem of self-rotation, which affects practical use.
