Abstract
The utility model discloses a PTFE (Polytetrafluoroethylene) base cloth and PPS (Polyphenylene Sulphide) needle-punched combined type filter material. PPS fibre coating needle-punched felts are symmetrically stuck at the upper and lower surfaces of the PTFE base clot; PTFE dip coating layers are arranged on an upper composite surface and a lower composite surface; and the PTFE dip coating layers can permeate an intermediate layer, an upper composite surface layer and a lower composite surface layer. The PTFE base cloth and PPS needle-punched combined type filter material has the characteristics of high temperature resistance, corrosion resistance, high filter fineness and the like.
Description
Technical field
The utility model relates to a kind of Nomex and base cloth combined type filtrate, particularly PTFE add PPS acupuncture combined type filtrate 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 it is very high to make under the situation of scrim material cost with PTFE fully, has had a strong impact on production and the use of filtrate.
Summary of the invention
The utility model is in order to solve above-mentioned deficiency, to provide a kind of filtering accuracy height, waterproof and oilproof antistatic, good, the lower-cost PTFE of corrosion-and high-temp-resistant to add PPS acupuncture combined type filtrate as base cloth.
Above-mentioned purpose of the present utility model realizes by following technical scheme: PTFE adds PPS acupuncture combined type filtrate as base cloth, comprises the PPS Nomex that paste on intermediate layer PTFE base cloth and base cloth two sides.
Superior function of the present utility model:
1, high temperature resistant: PTFE is high temperature resistant to reach 240 degree, and PPS can reach the 170-180 degree, can reach the 220-230 degree after the mixing.
2, corrosion-resistant: the PTFE good corrosion resistance, the PPS corrosion resistance is also good, and both mix the corrosion resistance better effects if.
3, reduce cost: PTFE 40W unit/t, PPS 10W unit/t, two mixing reduce production costs greatly.
4, dimensional performance is good: good permeability, tension fracture strength height.
5, filtering accuracy height: product adopts fiber to open technologies such as bud, shredding in production process, and the product dust-collecting face is superfine fibre filtration aspect.
6, antistatic behaviour: product adds antistatic additive and has good antistatic 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, the utility model provides a kind of PTFE to add PPS acupuncture combined type filtrate as base cloth, paste PPS fiber coat Nomex 2,3 in PTFE base cloth upper and lower surface symmetry, last composite surface and following composite surface 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 PPS Nomex 2,3 is in PTFE base cloth 1 upper and lower surface, and symmetry is pasted PPS and made the nonwoven needled felt through needing machine technology.
The utility model is dropped into actual operating mode to be used, through implementing proof, continuous serviceability temperature of the present utility model be 220 the degree, moment the serviceability temperature temperature be 230 the degree, warp-wise ultimate strength 1400-1500N/5*20cm, broadwise ultimate strength 1500-1600N/5*20cm, warp-wise elongation at break≤35%, broadwise elongation at break≤45%, rupture strength 3.6MPa, thickness 1.9-2.0mm, Air permenbility 300-450L/ ㎡ * min.
Claims (2)
1.PTFE add PPS acupuncture combined type filtrate as base cloth, comprise the intermediate layer, it is characterized in that: described PPS fibrogram layer Nomex is layer structure, pastes PPS in the upper and lower surface symmetry of PTFE base cloth.
2. PTFE according to claim 1 adds PPS acupuncture combined type filtrate as base cloth, and it is characterized in that: PTFE makes base cloth, and PPS makes Nomex.
