Abstract
The invention relates to a processing technology of alkali-free glass fiber/polyphenylene sulfide fiber nonwoven materials. A structure of the nonwoven materials is formed by compounding three layersof materials. A middle layer is alkali-free galss fiber woven fabric; an upper layer and a lower layer are the same needled nonwoven fabric made of alkali-free glass fibers/polyphenylene sulfide fibers, and the blended ratio by weight of the two fibers is (50-70):(50-25); the three layers of material are compounded by needled processing, and then polytetrafluoroethylene emulsion solution finish (impregnation and rolling) is carried out to ensure that polytetrafluoroethylene emulsion solution (dry state) is 10 to 12 percent of the weight of the whole materials. The invention belongs to the field of weaving the nonwoven materials. By adopting the technology to prepare the nonwoven materials, the folding resistance of the materials can be improved, and the heat stability of the nonwoven materials under a corresponding temperature of the service temperature is enhanced. After the polytetrafluoroethylene emulsion solution finish is carried out on the nonwoven materials after being compounded, a layer of film is formed on the surface of the fibers, thereby enhancing the performance of resisting acid materials and alkaline materials in flue gas of the materials under high temperature, andthe prolonging the service life thereof.
Description
Technical field
The invention belongs to weaving non-woven material field, particularly relate to a kind of processing technology of high-temperature-resistant filtering material.
Background technology
Glass fibre and polyphenylene sulfide fibre are widely used fibrous raw materials on the high temperature fume dust removal filtering material.The glass fibre acid resistance can be relatively good, but alkali-free glass fibre heatproof to 280 ℃ wherein, the performance that has anti-highly basic at normal temperatures, the price of glass fibre are also relatively more cheap, but the glass fibre folding resistance is relatively poor, at high temperature, the alkali corrosion resistance performance can obviously descend, and therefore, the high-temperature-resistant filtering material made from alkali-free glass fibre is not suitable in pulsed or the oscillatory type deashing device, in containing the flue gas of alkali, also corrosion-vulnerable and cause breakage; But polyphenylene sulfide fibre heatproof to 160 ℃, and have acidproof preferably and alkaline resistance properties concurrently, folding quality is fine.But polyphenylene sulfide fibre is after temperature surpasses 160 ℃, and its acid-proof alkaline also can obviously descend, and price is also than higher in addition, and therefore, the filtering material made from polyphenylene sulfide fibre is not suitable for being used for the occasion that flue-gas temperature surpasses 160 ℃.
Summary of the invention
The object of the present invention is to provide a kind of non-woven high-temperature-resistant filtering material of alkali-free glass fibre/polyphenylene sulfide fibre, can be used for environment temperature≤180 ℃, can be used for the smoke filtration dedusting that contains acid, alkali of pulsed or oscillatory type deashing device.
The invention provides the processing technology of a kind of alkali-free glass fibre/polyphenylene sulfide fibre non-woven filter material, it is characterized in that: be the compound of trilaminate material on the structure.The intermediate layer is the woven cloth of alkali-free glass fibre, and the warp-wise density of yarn is 20 pieces/inch, and latitudinal density is 23 pieces/inch, and surface density is (400 ± 5%) gram/rice
2Two-layer up and down is the needle fabric of identical alkali-free glass fibre/polyphenylene sulfide fibre, and the blending ratio of alkali-free glass fibre/polyphenylene sulfide fibre (weight ratio) is 50-75: 50-25, and the surface density of needle fabric is (200 ± 8%) gram/rice
2By acupuncture processing that trilaminate material is compound, the non-woven filter material after compound is again through ptfe emulsion arrangement (dipping and roll compacting), and the ratio (weight ratio) that makes ptfe emulsion (dry state) account for whole material is 10-12%.
Effect of the present invention:
1, according to a certain percentage alkali-free glass fibre/polyphenylene sulfide fibre is mixed and made into non-woven filter material, can improves the folding resistance of material, adapt to pulsed or oscillatory type deashing; Can improve the heat endurance under the serviceability temperature relevant temperature of this kind filtering material.
2, because ptfe emulsion has good heat-resisting quantity and acid and alkali resistance corrosive nature, arrangement by ptfe emulsion, make fiber surface form the film of one deck polytetrafluoroethylene (PTFE), can improve above-mentioned two kinds of corrosive natures that fiber is at high temperature resisted flue gas middle acid substance and alkaline matter, can enlarge the range of application of filtering material, prolong its service life.
The specific embodiment
Embodiment 1:
Blending ratio (weight ratio) alkali-free glass fibre/polyphenylene sulfide fibre=50: 50.
Two kinds of fibers are mixed, make surface density and be (200 ± 8%) gram/rice
2Needle fabric; The alkali-free glass fibre yarn line is made woven cloth, and warp-wise density is 20 pieces/inch, and latitudinal density is 23 pieces/inch, and surface density is (400 ± 5%) gram/rice
2Originally the non-weaving cloth of each multiple one deck alkali-free glass fibre/polyphenylene sulfide fibre of two sides of woven cloth is compound through acupuncture, the non-woven material that is composited is flooded and roll compacting through ptfe emulsion, and 135 ± 2 ℃ of oven dry down, finalized the design 3 minutes down for 185 ± 3 ℃.By regulating the concentration of ptfe emulsion, make dried non-woven material that the polytetrafluoroethylene (PTFE) of two kinds of different content ratios (weight ratio) be arranged, respectively be 10% and 12%.The performance of these two kinds of non-woven materials is as shown in table 1.
Table 1: sample is at 185 ± 3 ℃, performance (50: 50) after the condition hot test in 200 hours
Embodiment 2:
Blending ratio (weight ratio) alkali-free glass fibre/polyphenylene sulfide fibre=75: 25
The processing technology of non-woven material is described as embodiment 1.The shared ratio (weight ratio) of polytetrafluoroethylene (PTFE) respectively is 10% and 12% in two kinds of non-woven materials producing.The performance of these two kinds of non-woven materials is as shown in table 2.
Table 2: sample is at 185 ± 2 ℃, performance (75: 25) after the condition hot test in 200 hours
Data by table 1 and table 2 can be found out, adopt the non-woven material of technology preparation of the present invention, under the continuous high temperature condition, their dimensional stability, hole stability all is reasonable between powerful retentivity of machinery and fiber, goes for environment temperature and is no more than 180 ℃ smoke filtration dedusting occasion.
