Abstract
The utility model discloses a glass fiber and PTFE (Polytetrafluoroethylene) composite high-temperature resisting membrane-coating filter material, which comprises an intermediate layer. An upper fiber layer is arranged above the intermediate layer; a lower fiber layer is arranged below the intermediate layer; the intermediate layer, the upper fiber layer and the lower fiber layer are all provided with PTFE dipping membrane-plating layers; the PTFE dipping membrane-plating layers can penetrate into the intermediate layer, the upper fiber layer and the lower fiber layer; and the upper fiber layer is provided with an outer layer. Compared with the prior art, the advantages of the glass fiber and PTFE composite high-temperature resisting membrane-coating filter material are that: the filtering material is high temperature resistant; the filtering precision is high; the wear-resisting property, the fold-resisting property and the peeling strength are high; the service life is long; the acid-base resisting property is good; the moisture condensation is resisted; and the dust peeling property is good.
Description
[technical field]
The utility model relates to a kind of glass and PTFE complex fire resistant coated filter material.
[background technology]
At present; There are requirements at the higher level in industrial and mineral production divisions such as steel plant, power plant, garbage burning factory to heat-resisting quantity, acid and alkali-resistance, the filtering accuracy of filtrate; But existing filtrate is owing to exist the heatproof degree low; Deficiencies such as resistance to acids and bases is poor, filtering accuracy is lower can't reach the production demand, have caused inconvenience, disadvantage in process of production.
[utility model content]
The utility model is in order to solve above-mentioned deficiency, and a kind of high temperature resistant, glass and PTFE complex fire resistant coated filter material that filtering accuracy is high are provided.
The above-mentioned purpose of the utility model realizes through following technical scheme: a kind of glass and PTFE complex fire resistant coated filter material; Comprised the intermediate layer; It is characterized in that: top, said intermediate layer is provided with fibrage; Be arranged with fibrage in said intermediate layer; Said intermediate layer, go up and to be equipped with PTFE dipping coatings on fibrage and the following fibrage, said PTFE dipping coatings is permeable to the intermediate layer, goes up fibrage and following fibrage inside, said on fibrage be provided with skin.
Said intermediate layer is the glass fiber machine nonwoven fabric layer.
The said fibrage of going up constitutes with following fibrage fibreglass and PTFE fiber.
Said skin is the PTFE microporous film layers.
The utility model advantage compared with prior art is:
1, high temperature resistant, 240 ℃ of normal serviceability temperatures, moment serviceability temperature be 260 ℃.
2, dust-collecting face is a PTFE microporous membrane layer, and ultrafine dust is had good interception result, and filtering accuracy is high.
3, PTFE dipping coatings makes product have good wearability, fold resistance, long service life.
4, acid-proof alkaline is good, and resistive connection reveals, and dust peeling property is good.
[description of drawings]
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing, the 1-intermediate layer; The last fibrage of 2-; Fibrage under the 3-; 4-is outer.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
As shown in Figure 1; A kind of glass and PTFE complex fire resistant coated filter material; Comprised intermediate layer 1; It is characterized in that: 1 top, said intermediate layer is provided with fibrage 2, is arranged with fibrage 3 in said intermediate layer 1, said intermediate layer 1, goes up and is equipped with PTFE on fibrage 2 and the following fibrage 3 and floods the coatings (not shown); Said PTFE dipping coatings (not shown) is permeable to intermediate layer 1, goes up fibrage 2 and following fibrage 3 inside, said on fibrage 2 be provided with skin 4.
Said intermediate layer 1 is the glass fiber machine nonwoven fabric layer, and the said fibrage 2 of going up constitutes with following fibrage 3 fibreglass and PTFE fiber, and said outer 4 is the PTFE microporous film layers.
The utility model drops in power plant's tails dedusting on probation, and through experiment confirm, the continuous operation temperature of this product can reach 240 ℃; Moment, operating temperature can reach 260 ℃; Warp-wise brute force >=2000N/5 * 20cm, broadwise brute force >=2000N/5 * 20cm, air permeability are 10～15m3/m2min200Pa; System's running resistance is steady, and filtering accuracy is high.
