Abstract
The utility model relates to a PPS (Polyphenylene Sulphide) base cloth and acrylic fibre needle-punched filter material. The PPS base cloth and acrylic fibre needle-punched filter material is characterized by comprising an intermediate PPS base cloth layer and acrylic fibre needle-punched felts stuck at two sides of the base cloth. The PPS base cloth and acrylic fibre needle-punched filter material has the advantages of high filter fineness, high temperature resistance, good corrosion resistance, relatively low cost and the like.
Description
Technical field
The utility model relates to a kind of Nomex and base cloth combined type filtrate, particularly PPS add acrylic fiber needle punched filter material as base cloth.
Background technology
At present, the occasion that cement plant, steel plant, power plant, chemical plant etc. have higher requirements to the strainability of filtrate, but existing filtrate is because high temperature resistant, poor corrosion resistance, and filtering accuracy is low, and it is higher fully to make under the situation of scrim material cost with PPS, has influenced production and the use of filtrate.
Summary of the invention
The utility model is in order to solve above-mentioned deficiency, provides a kind of filtering accuracy height, high temperature resistant, good corrosion resistance, lower-cost PPS to add acrylic fiber needle punched filter material as base cloth.
[0004]Above-mentioned purpose of the present utility model realizes by following technical scheme: PPS adds acrylic fiber needle punched filter material as base cloth, acrylic fiber coat Nomex is layer structure, comprises intermediate layer PPS base cloth and the acrylic fiber needled felt that sticks on the base cloth two sides.
Superior function of the present utility model:
1, high temperature resistant: PPS is high temperature resistant to reach the 170-180 degree, and the acrylic fiber can reach 120 degree, can reach after the mixing about 150 degree.
2, corrosion-resistant: acrylic fiber good corrosion resistance, PPS corrosion resistance corrosion resistance is also good, and it is fine that both mix the corrosion resistance effect.
3, reduce cost: PPS 10W unit/t, about acrylic fiber 1W unit/and t, two mixing reduce production costs greatly.
4, filtering accuracy height: product adopts fiber to open technologies such as bud, shredding in production process, and dust-collecting face is superfine fibre filtration aspect.
5, antistatic behaviour: product adds antistatic additive and has good antistatic effect.
6, waterproof and oilproof: the water proofing property of acrylic fiber own is very good, and water absorption rate has only 0.01%-0.03%, and is better through the post processing waterproof effect.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among Fig. 1,1-intermediate layer, the last composite cover of 2-, composite cover under the 3-.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, it is that intermediate layer 1 adds acrylic fiber needle punched filter material as base cloth that the utility model provides a kind of PPS, described acrylic fiber coat Nomex is namely gone up composite cover 2, composite cover 3 is layer structure down, paste acrylic fiber coat Nomex in PPS base cloth upper and lower surface symmetry, last composite surface 2 and following composite surface 3 are equipped with PTFE dipping plated film layer (not marking among the figure), and described PTFE dipping plated film layer is permeable to intermediate layer 1, goes up composite cover 2, following composite cover 3.
Described acrylic fiber coat Nomex is in PPS base cloth intermediate layer 1 upper and lower surface, and symmetry is pasted the acrylic fiber and made the nonwoven needled felt through needing machine technology, namely goes up composite cover 2 and following composite cover 3.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous serviceability temperature of the present utility model be 150 the degree, moment the serviceability temperature temperature be 180 the degree, warp-wise ultimate strength 1300N/5*20cm, broadwise ultimate strength 1400N/5*20cm, warp-wise elongation at break≤30%, broadwise elongation at break≤40%, rupture strength 3.2MPa, thickness 2.0-2.2mm, Air permenbility 250-400L/ ㎡ * min.
