Abstract
The utility model discloses an aramid fiber composite needling filter material and comprises a middle layer. An upper composite surface layer is arranged above the middle layer and a lower composite surface layer is arranged below the middle layer. A polytetrafluoroethylene (PTFE) dipping film-coating layer is arranged on the middle layer, the upper composite surface layer and the lower composite surface layer respectively, and can permeate to the interiors of the middle layer, the upper composite surface layer and the lower composite surface layer. An outer layer is arranged on the upper composite surface layer. Compared with the prior art, the aramid fiber composite needling filter material has the advantages of being resistant to temperature and acid and alkali corrosion, good in abrasion resistance, bending resistance and peeling strength, capable of bearing high filtering load, stable in shock resistance, good in dimensional stability, high in strength, long in service life and fast in filtering speed.
Description
[technical field]
The utility model relates to a kind of aramid fiber composite acupuncture filtrate.
[background technology]
At present, there are requirements at the higher level in production divisions such as iron and steel, nonferrous smelting, chemical industry, carbon black, building materials, electric power to the heatproof of filtrate, corrosivity, stability, gas permeability etc., but existing filtrate is owing to exist the heatproof degree low, corrosion resistance, stability, gas permeability are relatively poor, powerful low, the big deficiency that waits of running resistance can't reach the production demand, has caused inconvenience, disadvantage in process of production.
[utility model content]
The utility model is in order to solve above-mentioned deficiency, a kind of heatproof to be provided, and corrosion resistance, stability, gas permeability are better, powerful high, and the little aramid fiber composite acupuncture filtrate of running resistance.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of aramid fiber composite acupuncture filtrate, comprised the intermediate layer, it is characterized in that: top, described intermediate layer is provided with composite cover, be arranged with composite cover in described intermediate layer, be equipped with PTFE dipping plated film layer on described intermediate layer, last composite cover and the following composite cover, described PTFE dipping plated film layer is permeable to the intermediate layer, goes up composite cover and following composite cover inside, and the described composite cover of going up is provided with skin.
Described intermediate layer is the woven layer of cloth of glass fibre.
The described composite cover of going up constitutes by aramid fiber and glass fibre with following composite cover.
Described skin is the PTFE coating.
The utility model advantage compared with prior art is:
1, heatproof: processing temperature is 240 ℃, moment serviceability temperature be 260 ℃.
2, it is good to have a good antiacid caustic corrosion, anti-wear performance, fracture resistance, peel strength, can bear the high load that filters.
3, shock resistance is stable, and dimensional stability is good, and is powerful high, long service life.
4, the rate of filtration can reach more than the 1.0m/min, and running resistance is little.
[description of drawings]
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing, the 1-intermediate layer; The last composite cover of 2-; Composite cover under the 3-; The 4-skin.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, a kind of aramid fiber composite acupuncture filtrate, comprised intermediate layer 1, it is characterized in that: 1 top, described intermediate layer is provided with composite cover 2, be arranged with composite cover 3 in described intermediate layer 1, be equipped with PTFE dipping plated film layer (not shown) on described intermediate layer 1, last composite cover 2 and the following composite cover 3, described PTFE dipping plated film layer (not shown) is permeable to intermediate layer 1, goes up composite cover 2 and following composite cover 3 inside, described on composite cover 2 be provided with skin 4.
Described intermediate layer 1 is the woven layer of cloth of glass fibre, and the described composite cover 2 of going up constitutes by aramid fiber and glass fibre with following composite cover 3, and described outer 4 is the PTFE coating.
The utility model drops in steel plant's blast furnace gas dry pulse bag type dust collector on probation, through experiment confirm, the continuous operation temperature of this product can reach 240 ℃, moment, operating temperature can reach 260 ℃, warp-wise ultimate strength 〉=2000N/5 * 20cm, broadwise ultimate strength 〉=2000N/5 * 20cm, warp-wise elongation at break≤10%, broadwise elongation at break≤10%, air permeability are 22m3/m2.min200pa.
