Abstract
The invention provides a polyphenylene sulfide fiber needled felt with a body membrane and a manufacture method thereof, aiming to solve the problem that a needled felt with a covering membrane enables micropores of the covering membrane to shrink during a hot pressing process, and contraction of a polyphenylene sulfide micropore can be again caused in use due to a high-temperature work condition so as to seriously affect the ventilation effect, and even affect the normal production of dust-removal enterprises; and the needled felt is subjected to repeated impact of air current and machines when the ash is cleared, and the covering membrane is easy to drop off. The invention adopts the essential that the surface of the polyphenylene sulfide fiber needled felt is provided with a layer of the body membrane produced by singeing and hot roller pressing. The invention has the characteristics of no dropping of the body membrane, good ventilation property, high dust-removal efficiency, smooth surface and easy ash clearing.
Description
Technical field
The present invention relates to be used in the high-temperature flue gas environment fabric of Chalk-dust filtering, said fabric is the polyphenylene sulfide fibre Nomex with body membrane.
Background technology
Because of polyphenylene sulfide (PPS) fiber has characteristics such as high temperature resistant, anticorrosive, it is made fabric such as Nomex, as the filtering material of high-temperature smoke.In order to improve the dedusting precision and the ABRASION RESISTANCE of Nomex, also need press one deck at the surface heat of polyphenylene sulfide fibre Nomex and contain microporous teflon membran or gluing last layer microporous teflon membran, as CN1223161 disclosed " multi-function glass fibre composite filter material and manufacture method a thereof " literary composition, press organic film that one deck contains polytetrafluoroethylene (PTFE) at the surface heat of glass fibre composite filter material (also being fiberglass needled mat).All adopt the method to produce this Nomex that is covering film that has at present in the sector, film and felt body are two kinds of materials.This have the Nomex that is covering film and have following defective:
The one, in hot pressing,, reduced the air penetrability of Nomex because high temperature makes and covering membrane micropore and cause contraction; Tacky film is because adhesive is blocking microporous, and air penetrability also can be had a greatly reduced quality.Nomex be in actual use because the working condition of high temperature can cause once more that covering membrane micropore shrinks, and air permeable effect further reduces, when serious even can influence the ordinary production in dedusting enterprise (as the power plant).The way that solves this technical problem at present is to realize by increasing filter area.But this method can make the volume of filter plant increase, and also can increase the use amount of filtering material, has improved the dedusting cost.For old scrap build, limited by place and appointed condition, the way that increases filter area almost can not realize.
The 2nd, in deashing process, Nomex is subjected to air-flow and mechanical repeated stock, and it is covering film and is easy to come off, and influences dust removing effects, has reduced the service life of Nomex.
Summary of the invention
For solution has the defective that the Nomex that covering film brings, the object of the present invention is to provide a kind of polyphenylene sulfide fibre Nomex and manufacture method thereof with body membrane.
The object of the present invention is achieved like this: it has the polyphenylene sulfide fibre Nomex, it is characterized in that: one deck is arranged through the body membrane of singing and the hot-rolling compacting forms on the surface of polyphenylene sulfide fibre Nomex.
Manufacture method is:
1, the polyphenylene sulfide fibre Nomex is placed on the gassing frame singes;
2, use the pressure roller press mold when dropping to about its fusing point (275～290 ℃) through the polyphenylene sulfide fibre Nomex surface temperature of singing, roller temperature is 140～160 ℃, and pressure roller pressure is 10～30Mpa, and the Nomex speed of service is 5～15m/min.
Above-mentioned said body membrane can form at the single or double of polyphenylene sulfide fibre Nomex.The porosity of polyphenylene sulfide Nomex body membrane can realize by the speed of service of adjusting roller temperature, pressure and Nomex, to adapt to different working conditions.These will specify in an embodiment.
Compared with prior art, the invention has the beneficial effects as follows: owing on the polyphenylene sulfide Nomex, form body membrane, so do not have the problem of coming off, the repeated stock that can bear deashing process, the service life of having improved filtering material.Next body membrane good permeability, efficiency of dust collection height, and smooth surface, easy-to-clean ash.
The specific embodiment
Provide two embodiment below, it just realizes reliable illustration of the present invention, and the purpose of enumerating following examples is to specify the present invention, and and unrestricted interest field of the present invention.The present invention can have various ways in the scope that does not exceed its technical thought.
Embodiment 1: single face press mold on the polyphenylene sulfide fibre Nomex
Technological process is: polyphenylene sulfide fibre Nomex → singe → heat fusing press mold → the have polyphenylene sulfide fibre Nomex finished product of certain porosity.
Detailed process and process conditions are as follows:
1, the polyphenylene sulfide fibre Nomex is placed on the gassing frame singes;
2, when dropping to about its fusing point (275～290 ℃) through the polyphenylene sulfide fibre Nomex surface temperature of singing, use pressure roller press mold, 154 ℃ of roller temperatures; Pressure roller pressure is 15.5MPa; The Nomex speed of service is 8m/min.
Embodiment 2: two-sided press mold on the polyphenylene sulfide fibre Nomex
Technological process is: the polyphenylene sulfide fibre Nomex finished product of the polyphenylene sulfide fibre Nomex of single face press mold → singe at no face → no face heat fusing press mold → two-sided press mold.
Detailed process and process conditions are as follows:
1, the polyphenylene sulfide fibre Nomex of single face press mold is placed on the gassing frame no face is singed;
2, when dropping to about its fusing point (275～290 ℃) through the polyphenylene sulfide fibre Nomex surface temperature of singing at no face use pressure roller press mold, 152 ℃ of roller temperatures, pressure roller pressure are 13.5Mpa, the Nomex speed of service is 10m/min.
Embodiment sample and polytetrafluoroethylene (PTFE) are covering film permeability comparison sheet
