A high performance, high security pickling sling

Abstract

The invention provides a high-property high-safety acid pickling hanging belt. The high-property high-safety acid pickling hanging belt is formed through lamination sewing of an upper layer belt, a middle layer belt and a lower layer belt; the number of weaving warp of the upper layer belt is 801, and the density of weft is 8 shuttles; the number of weaving warp of the middle layer belt is 801, and the density of weft is 8 shuttles; the number of weaving warp of the layer belt is 1000, and the density of weft is 8 shuttles; the weaving warp of the upper layer belt, the middle layer belt and the lower layer belt is acidproof warp, and the weft is acidproof weft; the acidproof warp is formed through twisting and stranding of polypropylene fiber silk, polyester silk, nylon silk and mixed silk, and the acidproof weft is formed through twisting and stranding of basalt fiber spinning yarn, nylon silk and mixed silk; firstly, through multi-layer lamination sewing, the safety coefficient is improved, more heavy lifting objects can be lifted, and safety work force is improved; through combination of different acidproof materials, the good whole acidproof property is formed, under long-timeacid corrosion, identification is easy, and the hidden risks are reduced.

Description

technical field [0001] The invention belongs to hoisting tools, in particular to a high-performance and high-safety pickling sling. Background technique [0002] The method of using an acid solution to remove scale and rust on the steel surface is called pickling. It is a method of cleaning metal surfaces. It is the pretreatment or intermediate treatment of electroplating, enamel, rolling and other processes. Iron oxides such as scale and rust react chemically with the acid solution to form salts that are dissolved in the acid solution and removed. in progress. In the prior art, during the pickling process, iron chains are often used for hoisting. However, the iron chain is first likely to collide with the inner wall of the pickling tank during use, resulting in frictional damage to the pickling tank. Furthermore, the iron chain cannot fit the hoisting object, causing the hoisting object to easily fall into the pickling tank, thereby causing production accidents and del...

Problems solved by technology

[0003] However, compared with iron chains, the existing slings still have poor acid resistance, and the slings are not easy to observe after being corroded by acid, and the risk of fracture is more hidden
