Abstract
The utility model relates to a PTFE (Polytetrafluoroethylene) base cloth and P84 needle-punched combined type filter material. The PTFE base cloth and P84 needle-punched combined type filter material is characterized by comprising a middle PTFE base cloth layer and P84 fibre needle-punched felts stuck at two sides of the base cloth. The PTFE base cloth and P84 needle-punched combined type filter material has the advantages of high filter fineness, good waterproof, oil-proof and anti-static performances, good high temperature and corrosion resistances, 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 PTFE add P84 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 filtering accuracy are low, and it is very high fully to make under the situation of scrim material cost with PTFE, has had a strong impact on quality and the development of filtering material.
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 P84 acupuncture combined type filtrate as base cloth.
Above-mentioned purpose of the present utility model realizes by following technical scheme: PTFE adds P84 acupuncture combined type filtrate as base cloth, and described PPS fiber is layer structure, comprises the P84 fiber needled felt 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 P84 can reach 240 degree, moment heatproof 260 degree.
2, corrosion-resistant: the PTFE good corrosion resistance, the P84 corrosion resistance is also good, and both mix the corrosion resistance better effects if.
3, reduce cost: PTFE 40W unit/t, P84 4W unit/t, two mixing reduce production costs greatly.
4, dimensional performance is good: good permeability, tension fracture strength height.
5, filtering accuracy height: PTFE itself has extraordinary filtering accuracy, can reach 99.9%, and base cloth does not efflux, and 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 P84 acupuncture combined type filtrate as base cloth, described PPS fiber is layer structure, paste P84 fiber coat Nomex in PTFE base cloth intermediate layer 1 upper and lower surface symmetry, namely go up composite cover 2 and following composite cover 3, last composite cover 2 and following composite cover 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.
[0010]Described P84 Nomex is in PTFE base cloth intermediate layer 1 upper and lower surface, and symmetry is pasted P84 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 240 the degree, moment the serviceability temperature temperature be 260 the degree, warp-wise ultimate strength 1550-1750N/5*20cm, broadwise ultimate strength 1650-1800N/5*20cm, warp-wise elongation at break≤35%, broadwise elongation at break≤45%, rupture strength 3.7MPa, thickness 1.9-2.1mm, Air permenbility 250-350L/ ㎡ * min.
Claims (2)
