Abstract
The invention relates to base cloth for a filter felt, in particular to basalt fibre base cloth for a high-temperature embroidered filter felt. The invention aims to provide the basalt fibre base cloth for the high-temperature embroidered filter felt, which has the advantages of thermostability, high strength, good acid and alkali resistance, moderate cost and durability. The technical scheme is as follows: the basalt fibre base cloth for the high-temperature embroidered filter felt is prepared through the processes of rewinding, twisting yarns, warping and weaving by taking basalt fibre yarns as a raw material and has the warp direction density of 45-55/10cm, the weft direction density of 55-65/10cm, the gram weight of 420-600g/m<2> and a plain weave structure as a tissue structure. The embroidered filter felt prepared by the invention can be used under high temperature up to 300 DEG C for a long term and instant use temperature of 350 DEG C, thereby having the advantages of great enhancement on the high-temperature resisting property, lower cost than high temperature resistant chemical fibre, strong pulling strength in the warp direction and the weft direction, better acid and alkali resistance than alkali-free glass fibre yarns, high cost performance and long service life.
Description
Technical field
The present invention relates to a kind of filter felt base cloth, particularly a kind of high temperature needled filtering felt basalt fibre base cloth.
Background technology
Needled filtering felt is the core component in the sack cleaner, plays a part the filtered air dust, is called as the heart of sack cleaner.With the base cloth is middle skeleton, adds chopped strand on the two sides of base cloth and makes by needling process.The needled filtering felt base cloth is the mid portion of needled filtering felt, plays a part skeleton and supports powerful.At present the high temperature needled filtering felt generally has medium-alkali glass fibre and alkali-free glass fibre in the inorfil or higher polyphenylene sulfide fibre, polytetrafluoroethylene fibre, polysulphonamide fiber and the pi fiber etc. of temperature tolerance in the chemical fibre with the material of base cloth.All below 260 degree, and the price of high temperature resistant chemical fibre is very expensive, causes the production cost of filter felt too high for the serviceability temperature of these fibers.
Summary of the invention
The present invention aims to provide a kind of high temperature needled filtering felt basalt fibre base cloth, and it is high temperature resistant, high strength, resistance to acids and bases are good, moderate, durable in use.
Technical scheme of the present invention is: a kind of high temperature needled filtering felt basalt fibre base cloth, it is a raw material with the basalt fibre yarn, separates, twists thread through moving back, warping, weaving process make.Its warp-wise density is 45-55 root/10cm, and latitudinal density is 55-65 root/10cm, grammes per square metre be 420-600 gram/square metre.Its institutional framework is a plain weave structure.
The filament diameter of described basalt fibre yarn is the 4.5-9 micron.
The described twist of separating of moving back is a 150-180 sth. made by twisting/rice,
The described twist of twisting thread is a 150-180 sth. made by twisting/rice.
Manufacturing technology steps of the present invention is as follows:
(1) chooses many basalt fibre continuous strands as raw material; The filament diameter of basalt fibre is the 4.5-9 micron, the fineness unanimity of the basalt fibre continuous strand of choosing.
(2) every basalt fibre continuous strand is moved back separate; Move back the direction of separating for " Z " to, the twist is a 150-180 sth. made by twisting/rice.
(3) will move back the basalt fibre continuous strand of separating and twist thread, promptly make the basalt fibre twisted yarn of weaving usefulness; The direction of twisting thread for " S " to, the twist is a 150-180 sth. made by twisting/rice.
(4) the basalt fibre twisted yarn is weaved by loom, and by transposing steel porter number, the filling density gear makes different product warp, filling density difference, forms the high temperature needled filtering felt basalt fibre base cloth with plain weave structure.The high temperature needled filtering felt combustible content 0.6-1% of basalt fibre base cloth, warp-wise density 45-55 root/10cm, latitudinal density 55-65 root/10cm, grammes per square metre 420-600 gram/square metre.
The present invention compared with prior art has the following advantages:
(1) needled filtering felt that uses the present invention to make can use under 300 degree high temperature for a long time, moment serviceability temperature can reach 350 the degree, make needled filtering felt can adapt to most of working environments, especially be suitable for high temperature waste incineration and steel plant's high temperature blast furnace gas purification, can be widely used in multiple fields such as electronics, chemical industry, building, shipbuilding, Aero-Space.
(2) its cost has only 1/3rd to 1/5th of high temperature resistant chemical fibre.
(3) its warp, broadwise are broken brute force and are higher than alkali-free glass fibre 10-20%, and its acid-proof alkaline is better than alkali-free glass fibre yarn, cost performance height, long service life.
The specific embodiment
The filament diameter of the basalt fibre yarn that the present invention uses is generally 5.5 microns, 7.5 microns and 9 microns three kinds.9 microns precursor are generally 15,7 microns and 7.5 microns former gauzes and are generally 18,5.5 microns precursor and are generally 30 or 40 during twisting.Be divided into 8 and move back and 5 twist with the fingers, 6 move back 5 and twist with the fingers, 5 move back 3 twist with the fingers etc. several, to satisfy the requirement of the base cloth of weaving different grammes per square metres.
Embodiment 1:
(1) with 6 of 5.5 microns basalt fibre continuous strands with " Z " to, move back and separate on the spool, the twist is 180 sth. made by twisting/rice;
(2) will move back 5 one threads of separating, on twisting machine with " S " to twisting, the twist is 180 sth. made by twisting/rice, forms the basalt fibre twisted yarn of balanced twist;
(3) the basalt fibre twisted yarn is weaved by loom, and by transposing steel porter number, it is that 50/10 centimetres, latitudinal density are 60/10 centimetres that the filling density gear makes warp-wise density, is woven into the high temperature needled filtering felt basalt fibre base cloth with plain weave structure.
The grammes per square metre of this base cloth be 420 grams/square metre, warp-wise is broken powerful greater than 1750N, broadwise is broken powerful greater than 1800N, it breaks the 10-20% that brute force is higher than existing alkali-free glass fibre yarn base cloth.
Embodiment two:
(1) with 5 of 9 microns basalt fibre continuous strands with " Z " to, move back and separate on the spool, the twist 150 sth. made by twisting/rice;
(2) will move back 3 one threads of separating, on twisting machine with " S " to twisting, the twist 150 sth. made by twisting/rice form the basalt fibre twisted yarn of balanced twist;
