Abstract
A production technology for novel high-temperature-resistant filter felt comprises arranging base cloth, carding to form a net, feeding a material and needling, dyeing and making a bag. The filter felt produced by employing the production technology is prolonged in service life, high in acid and alkali resistant degree and good in filtering effect, can realize high-speed high-efficiency filtering, is adaptive to various high-temperature environments, is excellent in high-temperature resistance, gives play to extremely good filtering effect, and is optimized in usage performances and prolonged in service life.
Description
Technical field
The invention belongs to filter technical field, be specifically related to a kind of production technology of novel fire resistant filter felt.
Background technology
In present filtering material; general filtering material Shortcomings in high temperature resistant; especially for the filtration of the high-temperature flue gas of the various industrial furnaces such as chemical industry, iron and steel, metallurgy, generating, cement; a lot of filtering material is short for service life; acid and alkali-resistance degree is low; use cost is higher; filter felt in use; usually there will be damage, add the cost of enterprise, in hot environment; reduce strainability; can not play good filter effect, the dust content in the middle of waste gas is more, pollutes surrounding environment.
Technology contents
The object of the invention is the production technology of inventing a kind of novel fire resistant filter felt, adopt production technology of the present invention can improve the acid and alkali-resistance ability of filter felt, reduce use cost, especially effect is especially obvious in high temperature resistant, is applicable to the filtering high-temperature flue gas being applied to each large industrial furnace.
Production technology of the present invention is as follows:
1) upper base cloth: base cloth is contained on needing machine
2) carding: be layered on by quartz glass fibre on combing machine for fur, starts combing machine for fur and material is carded to fleece;
3) material loading acupuncture: with needing machine, material is stung on base cloth, become filter felt;
4) dyeization: add 5-10% polytetrafluoroethylene (PTFE), 5-10% acid and alkali-resistance material and 5-10%285 silicone oil and carry out dyeization process;
5) bag: carry out sizing bag with heat-shaping machine.
Advantage of the present invention is:
The filter felt adopting the present invention to produce extends service life, acid and alkali-resistance degree is high, good filtration effect, can at a high speed, filter efficiently, be applicable to various hot environment, excellent effect in high temperature resistant, can play good filter effect, optimize the serviceability of filter felt, extend the service life of filter felt.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further described.
1) upper base cloth: base cloth is contained on needing machine;
2) carding: be layered on by quartz glass fibre on combing machine for fur, starts combing machine for fur and material is carded to fleece;
3) material loading acupuncture: with needing machine, material is stung on base cloth, become filter felt;
4) empty thorn: by filter felt in needing machine overhead thorn, strengthen the cohesive force of expecting with base cloth;
5) pricking method: the material stinging another side at sky, pricking method, in centre, is filter felt two sides all flat smooth;
6) dyeization: add 5% polytetrafluoroethylene (PTFE), 5% acid and alkali-resistance material and 5%285 silicone oil and carry out dyeization process;
7) severing: according to the requirement of user, is cut into filter felt the size of different size;
8) dry: filter felt is carried out natural drying in wind;
9) bag: carry out sizing bag with heat-shaping machine.
Application:
Pellet of the present invention is applied to the production of cable, cable product after testing, the index reached is as follows: tensile strength >=20MPa, fracture extension rate >=270%, hot strength retention rate 90%, oxygen index (OI) >=30%, dielectric strength >=20MV/m, 20 DEG C of specific insulation >=1.0 × 1012 Ω .m, impact brittle temperature >=-50 DEG C.
