Abstract
The utility model provides a special high-temperature-resistant alkaline-resisting GJ-1 filter material. The needle-punched filtering material structurally sequentially comprises a surface coating layer (1), a multiple performance GJ blending a layer (2), a multiple performance GJ blending b layer (4) and a PTFE special woven base fabric (3) from the outer layer to the inner layer, wherein the surface coating layer (1) adopts a heat seal manner to enable a PTFE microporous film to be fixed on the multiple performance GJ blending layer a (2); the multiple performance GJ blending layer a (2) and the multiple performance GJ blending layer b (4) are a main filtering layer body formed by blending filter material fibers mainly made of P84 fibers and PTFE; the PTFE special woven base fabric (3) is a base fabric specially woven by using polytetrafluoroethylene yarns, and needle-punched processing is performed on two sides of the base fabric. The filtering material has the advantages that the filtering precision is improved, and the friction coefficient is reduced, so that the filter material is wear-resistant well, and the service life of the filter material is prolonged; the filter material has excellent high-temperature-resistant and corrosion-resistant capacities, and while the cost is reduced.
Description
Technical field
The utility model technology relates to high temperature fume dust removal filtering material technical field, particularly the special-purpose filtrate of high temperature alkali resistant GJ-1.
Background technology
Pollutant in some circumstance complications (high temperature, high humidity, high corrosion etc.) operating mode discharging mainly contains flue dust, carbon monoxide, sulfur dioxide and fluoride etc.Be characterized in that flue gas corrosion is large, water capacity is large, dust specific resistance is large, fine dust is many, this gas also can produce harm greatly to filtrate, reduces filtrate intensity, causes filtrate damaged, and the maintenance and the cost that have greatly increased enterprise drop into.And now widely used product is the P84 filtrate, 240 ℃ of its heatproofs, and alkali resistance is general, and the finished product price is high; The aramid fiber filtrate, its heatproof degree is only 204 ℃; Weak point is both arranged, be difficult to reach the desirable requirement of enterprise, and cost is excessive.Therefore be badly in need of a kind of practicality and novel filtrate product with strong points, that Costco Wholesale is lower.
The utility model content
The purpose of this utility model is to provide the special-purpose filtrate of a kind of high temperature alkali resistant GJ-1.The long-term serviceability temperature of this filtrate is 200 ℃, moment serviceability temperature be 240 ℃.Improve alkaline resistance properties and filtering accuracy, reduced running resistance and cost, had higher cost performance.
The technical solution of the utility model is as follows.
A whole set of material mainly comprises: surface coating layer (1), adopt the heat seal mode that the PTFE microporous barrier is fixed on many performances GJ blending a layer (2); Many performances GJ blending a layer (2) and many performances GJ blending b layer (4) are the main filter course bodies that forms after take P84 fiber and PTFE as main filter media fibre blending; The special ply ground fabric of PTFE (3), adopt polytetrafluoroethylene wire to spin special woven base cloth, and acupuncture is on the base cloth both sides.
Surface coating layer (1) is covered on many performances GJ blending a layer (2), many performances GJ blending a layer (2) is covered on the special ply ground fabric of PTFE (3), the special ply ground fabric of PTFE (3) is covered on many performances GJ blending b layer (4), and wherein many performances GJ blending a layer (2), the special ply ground fabric of PTFE (3) and many performances GJ blending b layer (4) link reinforcing by the acupuncture complex method.
The utility model technology has following advantage:
1. filtrate relies on the PTFE micro-pore-film filtration on surface, has improved filtering accuracy, reduces coefficient of friction, makes filtrate more wear-resisting, increases service life;
2. take full advantage of the advantage of different filtrates, reasonably blending after collocation, make filtrate also reduce cost when possessing corrosion resistant premium properties;
3. after thermal finalization, has good resistance to elevated temperatures.

The specific embodiment
As shown in Figure 1: the special-purpose filtrate of the utility model high temperature alkali resistant GJ-1, this filtering material comprises surface coating layer (1), many performances GJ blending a layer (2), the special ply ground fabric of PTFE (3), many performances GJ blending b layer (4).The purpose of this utility model is achieved through the following technical solutions:
1) at first P84 fiber, PTFE and other filtrates are put together according to a certain percentage, by shredding, combing, then be pressed into many performances GJ blending a layer (2), many performances GJ blending b layer (4) after smooth;
2) polytetrafluoroethylene fibre is made into the special ply ground fabric of PTFE (3) with machine;
3) use needing machine first to carry out pre-needling, then carry out main acupuncture many performances GJ blending a layer (2), the special ply ground fabric of PTFE (3), many performances GJ blending b layer (4) are linked reinforcing;
4) make the set of PTFE microporous barrier form surface coating layer (1) in the upper heat seal mode that adopts of GJ blending a layer (2);
5) finally material is carried out thermal finalization, polishing, singes.
The special-purpose filtrate of high temperature alkali resistant GJ-1 of the present invention all surpass 1200N/5*20cm through the broadwise ultimate strength, its filtering accuracy reaches 99.999%, running resistance is lower than 800Pa, Air permenbility is 6.8m
3/ m
2Min, surface evenness is better.Filtering accuracy, equipment running resistance aspect all have obvious advantage.
Claims (3)
