Abstract

The utility model relates to a PPS (Polyphenylene Sulphide) base cloth and polypropylene fibre needle-punched combined type filter material. The PPS base cloth and polypropylene needle-punched combined type filter material is characterized by comprising an intermediate PPS base cloth layer and polypropylene fibre needle-punched felts stuck at two sides of the base cloth. The PPS base cloth and polypropylene fibre needle-punched combined type filter material has the advantages of high filter fineness, high temperature resistance, good corrosion resistance, good waterproof performance, relatively low cost and the like.

Description

PPS adds polypropylene fibre acupuncture combined type filtrate as base cloth

Technical field

The utility model relates to a kind of Nomex and base cloth combined type filtrate, particularly PPS add polypropylene fiber 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, filtering accuracy is low, the waterproof tensile property is relatively poor, 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, water resistance is good, cost is lower and the PPS of flexible does base cloth and adds polypropylene fibre acupuncture combined type filtrate.

[0004]Above-mentioned purpose of the present utility model realizes by following technical scheme: PPS adds polypropylene fibre acupuncture combined type filtrate as base cloth, and the polypropylene fibre Nomex is layer structure, comprises intermediate layer PPS base cloth and the polypropylene fibre Nomex 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 polypropylene fibre can reach 110 degree, can reach after the mixing about 150 degree.

2, corrosion-resistant: polypropylene fibre has good acid-fast alkali-proof wearability, and 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, polypropylene fibre 1W unit/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 polypropylene fibre own is very good, and water absorption rate has only 0.03%, adds waterproof and oilproof better effects if behind the water and oil repellent agent again.

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 PPS to do base cloth and has added polypropylene fibre acupuncture combined type filtrate, the polypropylene fibre Nomex is namely gone up composite cover 2, composite cover 3 is layer structure down, paste the polypropylene fibre Nomex in PPS base cloth intermediate layer 1 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 polypropylene fibre Nomex is in PPS base cloth intermediate layer 1 upper and lower surface, and symmetry is pasted polypropylene fibre 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 140 the degree, moment the serviceability temperature temperature be 160 the degree, warp-wise ultimate strength 1250N/5*20cm, broadwise ultimate strength 1300N/5*20cm, warp-wise elongation at break≤26%, broadwise elongation at break≤32%, rupture strength 3.4MPa, thickness 2.0-2.2mm, Air permenbility 230-420L/ ㎡ * min.

Claims

1.PPS add polypropylene fibre acupuncture combined type filtrate as base cloth, comprise the intermediate layer, it is characterized in that: described polypropylene fibre Nomex is layer structure, pastes polypropylene fibre in the upper and lower surface symmetry of PPS base cloth.

2. PPS according to claim 1 adds polypropylene fibre acupuncture combined type filtrate as base cloth, and it is characterized in that: PPS makes base cloth, and polypropylene fibre is made Nomex.
