Dacron normal-temperature needle-punched felt with shrinking function

Abstract

The invention discloses a dacron normal-temperature needle-punched felt with a shrinking function. The dacron normal-temperature needle-punched felt comprises an elastic needle-punched felt and a bearing connecting hole, wherein an elastic dacron layer is arranged at the lower end of the elastic needle-punched felt, and a transparent resin layer is arranged at the lower end of the elastic dacron layer. An elastic heat preservation layer and an elastic fireproof layer are arranged, so that a first thin film outside a gauze net is taken down, then a first fixing adhering layer is fixedly connected with the upper end of the elastic needle-punched felt, and consequently the elastic needle-punched felt is provided with heat preservation performance; then the other first thin film is taken down,a second thin film of the elastic fireproof layer is taken down at the same time, and the other first fixing adhering layer is fixedly connected with a second first fixing adhering layer, so that theelastic needle-punched felt has fireproof performance, consequently the elastic needle-punched felt is not easily damaged, and industrial equipment can be prevented from being damaged in cold weather. The service life of the needle-punched felt is prolonged, and production cost is further reduced.

Description

technical field [0001] The invention belongs to the related technical field of needle-punched felt, and in particular relates to a polyester normal-temperature needle-punched felt with shrinkage function. Background technique [0002] Needle-punched felt is a felt-like non-woven fabric filter material made by needle-punching the carded fibers, mechanically entangled the fibers, and reinforced the fiber web. Socks are woven horizontally and vertically, while needle felt is indeed made of barbed needles that are repeatedly stabbed, so there is still a big difference. Needle-punched felt is widely used. The wool is thicker. The product has the characteristics of high temperature resistance, high pressure resistance and corrosion resistance. In industry, it is mainly used for sealing dustproof, cushioning liner, packaging items, filtering liquid, heat insulation and oil protection. The role of oil. It can also be used to prevent cold. The treatment of industrial waste gas main...

AI Technical Summary

Problems solved by technology

The treatment of industrial waste gas mainly adopts the method of needle-punched felt filtration. In steel, metallurgy, chemical industry, pharmaceutical and other industries, the temperature of flue gas is relatively high, and the corrosiveness is also strong. The destruction of the filter needle felt will shorten the service life of the filter needle felt and increase the production cost of the enterprise

[0003] The existing needle-punched felt technology has the following problems: when the existing needle-punched felt is used, because the needle-punched felt itself does not have the effect of heat preservation and fire prevention, and also does not have elasticity, most of the Needle felt is used in industrial production, so the needle felt is easily damaged, and the industrial equipment will be damaged in cold weather, which not only reduces the service life of the needle felt, but also increases the production cost
