Abstract
A production technology for continuous basalt fiber needled felt is disclosed and comprises arranging base cloth, carding to form a net, feeding a material and needling, dyeing and making a bag. The produced filter felt is prolonged in service life and good in filtering effect, does not easily generate static electricity, is optimized in high-temperature resistance, is adaptive to high-temperature working environment and is prolonged in service life.
Description
Technical field
The invention belongs to filter technical field, be specifically related to a kind of production technology of continuous basalt fiber Nomex.
Background technology
In present filtering material, general filtering material easily produces electrostatic, not easily carding, especially high temperature resistant, anti-oxidant aspect performance is not fine, decrease life cycle, add production cost, cause the financial burden of manufacturing enterprise, be unfavorable for the large-scale production of filter felt, have impact on the filter effect of filter felt, make in the middle of the waste gas of discharge containing too high dust, pollute the environment of surrounding, in use procedure, filter felt often can not adapt to high temperature, the working environment of high humidity, cause filter felt very easily damaged, shorten the service life of filter felt.
Summary of the invention
The object of the invention is the production technology of inventing a kind of continuous basalt fiber Nomex, adopt production technology of the present invention can improve the heat-resisting quantity of filter felt, reduce use cost, strengthen the anti-oxidant of filter felt, reduce the generation of electrostatic.
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 combing machine for fur by the staple fibre of the short basalt fiber of 70-75%, 10-20% staple glass fibre and 10-15%, 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), 28-35% emulsion and 10-15%285 silicone oil and carry out dyeization process;
5) bag: carry out sizing bag with heat-shaping machine.
The invention has the beneficial effects as follows:
The filter felt service life adopting the present invention to produce extends, and good filtration effect, not easily produces electrostatic, optimizes the resistance to elevated temperatures of filter felt, and filter felt can be allowed to adapt to the working environment of high temperature, extends filter felt service life.
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: by the short basalt fiber of 70%, 10% staple glass fibre and 10% staple fibre be layered on combing machine for fur, start combing machine for fur 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 10% polytetrafluoroethylene (PTFE), 28% emulsion and 10%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.
