Abstract
The utility model discloses an anti-static spunlaced felt composited with glass fiber filter cloth, PPS (polyphenylene sulfite) and PTFE (polytetrafluoroethylene). The spunlaced felt is in a stratified structure and comprises glass fiber filter cloth and anti-static fiber layers, wherein the glass fiber filter cloth is arranged at a middle layer, the anti-static fiber layers are respectively adhered to the upper and lower surfaces of the glass fiber filter cloth, and a dense PPS-PTFE mixed fiber layer is coated on one anti-static fiber layer positioned on a windward side by virtue of a foaming machine; the anti-static fiber layers are formed by mixing PPS fibers with stainless steel fibers. The anti-static spunlaced felt is good in anti-static performance, strong in acid-base resistance, high in filter precision, easiness in dust cleaning and long in service life.
Description
[technical field]
The utility model relates to a kind of water thorn felt, particularly a kind of anti-static glass fiber filter cloth and PPS, PTFE composite spunlace felt.
[background technology]
At present, in industries such as the lower occasion ，Ru power plant of some filtrating smoke dust temperature, iron-smelter, garbage burning factory, blast furnace gas factories, the diameter of its dust granules thing is less, filtering accuracy requires very high, and traditional Nomex can not meet its higher filtering accuracy and decay resistance.
[summary of the invention]
The purpose of this utility model is to overcome deficiency of the prior art, and a kind of Heat stability is good, resistance to chemical corrosion is good, filtering accuracy is high anti-static glass fiber filter cloth and PPS, PTFE composite spunlace felt are provided.
The purpose of this utility model is achieved in that described water thorn felt is layer structure, the antistatic fibre layer that it comprises intermediate layer glass base cloth and sticks on respectively glass base cloth top and bottom, is positioned on the antistatic fibre layer of windward side and coats PPS and the PTFE mixed fiber layer of one deck densification with foaming machine.
In said structure, described antistatic fibre layer is mixed by PPS fiber and stainless steel fibre.
In said structure, described antistatic fibre layer is to inject on described glass base cloth by high-pressure water-jet.
Compared with prior art, the beneficial effects of the utility model are:
1) antistatic property is good;
2) acid resistance, alkaline corrosion are strong;
3) high, the easy-to-clean ash of filtering accuracy;
4) long service life.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[specific embodiment]
Below in conjunction with the drawings and the specific embodiments, the utility model is further described:
As shown in Figure 1, anti-static glass fiber filter cloth of the present utility model and PPS, PTFE composite spunlace felt, described water thorn felt is layer structure, the antistatic fibre layer 2 that it comprises intermediate layer glass base cloth 1 and sticks on respectively glass base cloth 1 top and bottom, is positioned on the antistatic fibre layer 2 of windward side and coats PPS and the PTFE mixed fiber layer 3 of one deck densification with foaming machine.
Wherein, the three-dimensional fiber layer that described antistatic fibre layer 2 is mixed by a certain percentage by PPS fiber and stainless steel fibre, it sticks on described glass base cloth 1 is to inject by high-pressure water-jet.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous operation temperature of the present utility model is 120 ℃～190 ℃, moment, serviceability temperature was 210 ℃, warp-wise Qiang Li≤900N/5 * 20 ㎝, broadwise Qiang Li≤1200N/5 * 20 ㎝, warp-wise elongation at break≤25%, broadwise extension at break≤45%, rate air permeability 2～5m
