Abstract
A Basalt fiber 3D woven filter material is characterized in that Basalt twisted yarn of 66 to 100 tex or Basalt untwisted yarn processed through PTFE is used as warp yarn; and Basalt untwisted yarn of 66 to 100 tex or Basalt bulky yarn is used as weft yarn. The Basalt fiber 3D woven filter material not only has the advantages of maintaining high intensity of woven fabric and good dimensional stability, but also can overcome the defect that woven fabric is low in filtering efficiency and needs a film coating. Pure Basalt fiber fabric which is not interwoven with other fiber can better take the advantages of high-temperature resistance and acid resistance of Basalt fiber, so that an active role is played in environmental protection.
Description
Technical field
The present invention relates to a kind of basalt fibre three-dimensional woven filtrate.
Background technology
The fume emission of industries such as thermal power generation, cement, metallurgy, waste incineration causes severe contamination to air quality, and diameter can be accumulated in the respiratory system after being sucked by the people less than 10 microns pellet, causes numerous disease.In addition, floating particle also makes visibility reduce in the air.Country pays much attention to environmental protection at present, has formulated the pollutant emission index of a series of national standard standard every profession and trades.Like GB 13223-2003 thermal power plant atmosphere pollutants emission standards, GB 4915-2004 cement industry atmosphere pollutants emission standards, GB 9078-1996 industrial furnace atmosphere pollutants emission standards, GB 16171-1996 coke oven atmosphere pollutants emission standards and GB 13271-2001 emission standard of air pollutants for boilers.The sack cleaner filter efficiency is high, can reduce smoke dust discharge concentration effectively.Sack cleaner is replacing electrostatic precipitator step by step and is becoming the principal mode of smoke dust-removing equipment.
The core of sack cleaner is a filter material, and the Development and Production of high-performance fiber is for sack cleaner universal provides technical guarantee.The fibrous material that is applied to the high-temperature flue gas filtration at present mainly contains polyphenylene sulfide fibre (PPS), pi fiber (P84), polytetrafluoroethylene fibre (PTFE), glass fibre etc.The serviceability temperature of these fibers is all below 260 ℃, only anti-190 ℃ of polyphenylene sulfide fibre (PPS).Pi fiber (P84) though 260 ℃ of abilities, acid resistance is poor.In addition, it is relatively cheap to remove the glass fibre price, and the price of other three kinds of fibers is also expensive.Basalt fibre has good temperature tolerance, along with the rising of temperature, though intensity has decline, still can reach about 10cN/tex in the brute force of 350 ℃ of fibers, so basalt fibre can use below 350 ℃ for a long time.Basalt fibre has good acid resistance, immerses the basalt fabric H of 85 ℃ of mass fractions 60%
2SO
4Solution, fabric is excellent after 24 hours.
The filter structure that is applied to the high-temperature flue gas filtration at present mainly is Nomex and two-dimentional woven fabric.The relative woven fabric of the intensity of Nomex nonwoven is less, and service life is short.The filter efficiency of two dimension woven fabric is low, will on fabric, carry out overlay film usually and could improve filter efficiency.The structure of three-dimensional woven filtrate is more abundant, be the yarn branch in multilayer, can weave the bigger fabric of tightness, form in-depth filtration.
Summary of the invention
Technical problem to be solved by this invention provides a kind of basalt fibre three-dimensional woven filtrate.
Adopt following technical scheme in order to solve the problems of the technologies described above: a kind of basalt fibre three-dimensional woven filtrate; The basalt zero twisted yarn that warp thread selects for use the basalt of 66 ~ 100tex twist yarn to be arranged or handle through PTFE, weft yarn is selected basalt zero twisted yarn or the basalt buiky yarn of 66 ~ 100tex for use.
Basalt has the filament diameter of twist yarn, basalt zero twisted yarn and basalt buiky yarn to be 7 ~ 13 microns.
Warp-wise tightness or broadwise tightness have at least one to reach more than 90%.
Total tightness degree reaches more than 98%.
Described basalt fibre three-dimensional woven filtrate adopts the angle interlocking to organize the high closely multiply cloth of weaving.
Basalt fibre three-dimensional woven filtrate of the present invention can keep the advantage that woven fabric intensity is high, dimensional stability is good, and it is low to improve the woven fabric filter efficiency again, needs the shortcoming of overlay film.With the pure basalt fibre fabric of other fiber interweavings, it is not high temperature resistant more to make full use of basalt fibre, and acidproof advantage is for positive effect has been played in environmental protection.
The specific embodiment
The basalt zero twisted yarn that a kind of basalt fibre three-dimensional woven filtrate, warp thread select for use the basalt of 66 ~ 100tex twist yarn to be arranged or handle through PTFE, weft yarn is selected basalt zero twisted yarn or the basalt buiky yarn of 66 ~ 100tex for use.
Basalt has the filament diameter of twist yarn, basalt zero twisted yarn and basalt buiky yarn to be 7 ~ 13 microns, and the special number of warp thread, weft yarn (tex) is identical, also can be different.Can be designed to the angle-interlock fabric of the various numbers of plies as required, as three layers, four layers, five layers ...Warp-wise tightness or broadwise tightness have at least one to reach more than 90%, and total tightness degree reaches more than 98%.Gait and can adopt, be easy to memory along wearing method, easy to operate.Every dent penetrates multiple or the approximate number that number should equal to organize period or organize period.To select the little porter of density during denting, reduce the friction of reed, enhance productivity warp thread.The extension at break of basalt fibre has only about 2%, and warp tension is wanted evenly to reduce warp end break when weaving.If adopt fly-shuttle loom production, because basalt fibre is more crisp, limit portion warp thread breaks end easily, adopts the good fiber (like the PTFE silvalin) of wearability to make the limit yarn, helps enhancing productivity.Because basalt fibre is more crisp, warp end break can not be tied a knot when weaving, can only be bonding, and adopt solid gum bonding.To glue fabric with transparent adhesive tape before the machine under the fabric, cut off again, in order to avoid fabric is decoherenced.
Basalt fibre three-dimensional woven filtrate need not carry out back arrangement, and it is compound not need to carry out acupuncture or water thorn again, does not also need overlay film, can be directly as fire resistant filter material.
