What are the laminating processes of glass fiber coated filter material?

Glass fiber coated filter media include continuous glass fiber woven woven coated filter material, glass fiber expanded yarn coated filter material and glass fiber needle felt coated filter material, glass fiber coated filter material has been widely used in high-temperature bag-type dust collectors, and the effect is excellent, especially in large-scale high-temperature bag-type dust collectors.

There are two kinds of laminating processes for domestic glass fiber coated filter media.

One is the international general hot pressing laminating technology, the glass fiber coated filter material produced by this technology has high dust removal efficiency, low running resistance, long service life, no film falling off, can work for a long time under the working conditions of 260 (instantaneous temperature can reach 300), all the properties of the filter bag have no change, the service life of the filter bag can reach more than 2 years, and the hot pressing and laminating technology is the most advanced technology recognized in the world.

Another laminating method is to bond the PTFE film on the glass fiber substrate with adhesive (referred to as the adhesive method), according to our performance test of the glass fiber laminated products of many domestic adhesive coated filter material manufacturers, the results show that the temperature resistance is not enough, and the adhesive used for bonding has melted when the temperature of the adhesive glass fiber coated filter material reaches 100, and the following problems will occur in the filter bag

1) The film falls off, due to the melting of the adhesive, the fastness of the coating between the film and the base cloth of the coated filter material has been greatly reduced, and the film will gradually be pushed down from the base cloth under the action of ash cleaning air pressure, resulting in the phenomenon of film falling off.

2) The resistance of the dust collector rises, according to the normal situation, the dust collector using the coated filter bag should have low resistance, but because the adhesive coated filter material reaches more than 100 at the temperature, the adhesive has been melted, and the melted adhesive is in a liquid state on the surface of the filter bag, resulting in a large amount of dust being faintly stuck on the surface of the filter bag, due to the strong adhesive ability of the adhesive, the dust on the surface of the filter bag can not be removed, but will be seriously agglomerate, resulting in a significant increase in resistance, at this time, if the filter bag is removed, Zen Lu will find that the filter bag has become hard, and the clumps on the surface are difficult to scrape off with a knife.

3) The service life of the filter bag is short, because the surface of the filter bag is all agglomerated and the resistance of the dust collector continues to rise, the filter bag will be blocked quickly.

To sum up, the glass fiber coated filter material is a high-efficiency, low-resistance, long-life high-temperature resistant filter material, but the hot-pressed coated glass fiber coated filter material must be selected, otherwise it is not possible to achieve the effect of high efficiency, low resistance, and long life.

Glass fiber coated filter media has been widely used in high-temperature baghouse dust collectors, and the effect is excellent, especially in large-scale high-temperature baghouse dust collectors.

What is the boring composite process of glass fiber coated filter media? I feel that his composite process like this glass fiber permeable coated membrane filter material is still more traveling, and I think it is still good.

Under normal circumstances, I think that if you keep entering this composite process, the main thing is that you can still purchase in three directions.

The laminating process of glass fiber coated filter media is very complicated. There are multiple layers of spraying.

There are two kinds of laminating processes for glass fiber coated filter media in Guoyu. One is the internationally used hot pressing and laminating technology, and the glass fiber coated filter material produced by this technology has high efficiency in dust removal, low resistance to the transportation chain, long service life, and no film falling off.

There are two kinds of laminating processes for domestic glass finger Li glass fiber coated filter material. One is the internationally used hot pressing and laminating technology, and the glass fiber coated filter material produced by this technology has high dust removal efficiency, low running resistance and service life.

There are two kinds in China: one is the internationally common hot pressing laminating technology, the glass fiber coated filter material produced by this technology has high dust removal efficiency, low running resistance, long service life, no film falling off, can work for a long time under the working conditions of 260 (instantaneous temperature can reach 300), all the properties of the filter bag have no change, the service life of the filter bag can reach more than 2 years, and the hot pressing laminating technology is the most advanced technology recognized in the world.

Another laminating method is to bond the PTFE film to a fiberglass substrate with an adhesive (abbreviation, adhesive method).

The glass fiber coated filter material is a high-efficiency, low-resistance, long-life high-temperature resistant filter material, but the user must choose the hot-pressed coated glass fiber coated filter material, otherwise you will not be able to achieve the effect of high efficiency, low resistance and long life. We have encountered a lot of manufacturers who use glass fiber coated filter media, they think that the coated filter material is similar to the ordinary filter material, and even the use effect is a little worse than the ordinary filter material, which is the result of their wrong choice of adhesive glass fiber coated filter material.

Another laminating method is to bond the PTFE film on the glass fiber substrate with adhesive (referred to as the adhesive method), according to our performance test of the glass fiber laminated film products of many domestic adhesive coated filter material manufacturers, the results show that the temperature resistance is not enough to be weak, and the adhesive used for bonding has melted when the temperature of the adhesive glass fiber coated filter material reaches 100.

There are two kinds of laminating processes for domestic glass fiber friendly silver coated filter media. One is the internationally used hot-pressed laminating technology, which uses this technology to produce glass fiber rent-to-rent and maintenance membrane filter material, which has high dust removal efficiency, low running resistance and long service life.

Dear, I'm glad to answer for you: Is the glass fiber filter paper a composite material A dear hello The glass fiber filter paper is not a composite material The glass fiber filter paper is made of 100% glass fiber. Fiberglass filter paper has the characteristics of high flow rate, high dirt holding capacity, and can filter fine particles.

Compared with other fibrous materials and synthetic materials, glass fiber filter paper has higher filtration efficiency and stronger dirt-holding capacity. The production of glass fiber filter paper for equipment factories and laboratories using relatively precise instruments Glass fiber filter paper is a kind of filter material and filial piety material. Glass fiber filter paper has the characteristics of good isotropy, uniform pore size distribution, small quantitative deviation, heat resistance, flame retardant, water resistance, and large dirt holding capacity.

I hope you are satisfied with my service and I wish you all the best again! Peace and joy!

The difference between the glass fiber filter and the PP filter (or other chemical fiber composites) is that the glass fiber filter only relies on the barrier (collision interception and sieve effect), while the chemical fiber has an electrostatic adsorption effect (and it has a large proportion of electrostatic adsorption with incomplete reliable testing). The adsorption effect of chemical fibers you are talking about should refer to electrostatic adsorption, not the adsorption of activated carbon!

The chemical fiber filter has no adsorption effect on odors! The fiber diameter and pore size of the glass fiber filter are much smaller than that of chemical fiber! Both of them can breed bacteria, but the bacteria of the glass fiber cannot pass through the filter screen (of course, the bacteria on the air outlet side can fly out, but they will also be blocked on the filter screen when they turn back).

Bacteria are generally not adsorbed by electrostatics, so it is difficult for chemical fiber filters to block bacteria!! In addition, according to the test, the dust holding capacity of the glass fiber filter is much greater than that of chemical fiber! And the efficiency doesn't decrease!

As for the cost. Now it's pretty much the same! As for the wind resistance, glass fiber is several times that of chemical fiber--- Corinnell fresh air purifier answers.

Coated filter bag, the so-called coated membrane is PTFE (poly-tetrafluo-roethylene) through high-tech special processing to expand into an extremely strong and flexible continuous porous microstructure plastid. **1 is an electron microscope used to compare the traditional surface treatment filter material with the coated surface**. It has a finer and more uniform structure than other materials, so it has a high porosity and can be reliably captured even with fine powders, and because it is a 100% PTFE coated material, it has high release, heat resistance (-24 -+26), chemical resistance (except for molten alkaline metals and activated fluorine gas), and does not deteriorate under all conditions.

Fiberglass coated filter bags.

The production of coated filter bags is based on a set of strict production technology, and the PTFE microporous membrane is individually manufactured by warp and weft stretching. Pressure and high temperature are used to laminate different needle felt surfaces. When laminating with thermoplastic fiber felt, the surface of the felt is treated with a special surface treatment technology and then laminated with PTFE film.

Non-thermoplastic fiber mats must be subjected to surface chemical, teflon treatment before being laminated with PTFE. In addition, some special fibers require a special chemical treatment to achieve the strongest possible fit.

PTFE films have a micropore size of 75-90%. Such a high microporous porosity is sufficient to allow a large amount of dense water vapor to pass freely through due to the fact that tiny water vapor molecules can diffuse freely and pass through the voids of the film. Due to its excellent corrosion resistance to any chemical, PTFE films can be used in a variety of different chemical production processes.
