PPS filter bag

PPS filter felt is the selection of the United States, Japan and other countries produced (PPS) polyphenylene sulfide fiber, according to the production process of other high temperature filter felt, the production and processing of filter materials, as one of the main varieties of high temperature filter materials. PPS needled filter materials are excellent in the following applications. 1, working temperature 170℃, short-time working temperature 232℃, melting point 285℃, limiting oxygen index 34~35. 2, oxygen content in 15% or below the occasion can be applied. 3, sulfur in the fuel or sulfur oxides in the flue gas, has been proved to be acid-base corrosion resistance, chemical resistance is very strong fiber. 4, the flue containing moisture occasions. 5, under the temperature of 190℃~232℃ mining conditions, the gas cloth ratio of up to 5:1 for online cleaning and gas cloth ratio of 6:1 for offline cleaning, PPS filter bag has excellent performance records. PPS fiber has complete retention of strength and intrinsic chemical resistance, which can maintain good filtration performance in harsh environments and achieve ideal service life. PPS filter felt is the ideal filter material in the pulse-cleaning dust collector of coal-fired boiler, waste incinerator, power plant fly ash collection and so on.

Matas filter bag

Matas needle felt can be continuously operated at 204 ° C (instant temperature 250 ° C) and can withstand repeated 250 ° C instant temperature fluctuations, while having excellent dimensional stability, at 250 ° C temperature only less than 1% thermal shrinkage, with excellent high temperature stability. Good chemical resistance at low concentrations of acids and bases and most hydrocarbons will not affect it, even a small amount of fluoride will not significantly corrode it. Matas filtration materials have proven to be widely used in the field of high temperature filtration, maintaining high strength and high wear resistance over a long period of time. Widely used in asphalt, cement, steel, non-ferrous metals, lime, dust, metallurgy, drying, gravel, gypsum, plastic, carbon black, coke, shipbuilding, tobacco and other industries.

Flumas filter bag

Compared with the glass fiber filter, the wear resistance, folding resistance and peeling strength of Flumace composite needled felt filter are significantly improved. Compared with chemical fiber filter material, it overcomes the weakness of chemical fiber filter material elongation deformation, good dimensional stability, and at the same time, compared with NOMEX coated filter material, it is a more ideal filter material, which is welcomed by users. Temperature resistance: 150℃, 200∽250℃/280℃ Application: steel, smelting, ferroalloy, chemical industry, cement, calcium carbide, waste incineration, electricity, asphalt mixing, etc.

Glass fiber needle filter bag

The filter material is a kind of high temperature resistant filter material with reasonable structure and good performance. It not only has the advantages of glass fiber fabric high temperature resistance, corrosion resistance, dimensional stability, small elongation shrinkage, high strength, and felt fiber bearing single fiber, three-dimensional microporous structure, high porosity, low resistance to gas filtration, is a high speed and efficient high temperature filtration material. Compared with other high temperature resistant chemical fiber felt, it has the special advantages of low price, low running resistance, high filtration accuracy and higher temperature resistance. Suitable for high temperature flue gas filtration in steel, metallurgy, carbon black, power generation, cement, chemical industry, etc.

Polyester anti-static filter bag

After the concentration of general industrial dust reaches a certain degree (that is, the explosion limit), such as electrostatic discharge sparks or external ignition and other factors, it is easy to lead to explosion and fire. For example, face dust, chemical dust, coal dust, etc. have the possibility of explosion in case of electrostatic discharge. In the field of bag dust removal, if these dust need to be collected by cloth bags, it is required that the filter material made of dust bags has anti-static properties. Our company absorbs and digests foreign technology, and develops and produces anti-static needle filter felt and filter cloth according to the needs of domestic BF gas coal mill dust collection and cement mill dust collection and other industries. In addition to the process of producing ordinary needled felt, the production of antistatic filter cloth also requires the incorporation of conductive fiber yarn in the warp of the base cloth for the production of needled felt or the mixing of conductive fiber and other conductive materials in the chemical fiber.

Polyester water and oil repellent filter bag

Our company is committed to the development of post-finishing technology, equipped with domestic ****** filter material post-finishing equipment, products through singeing, calendering, dipping, coating, drying, shaping and other processes, the post-treatment level in the leading position in China. The production process of water-repellent and oil-proof needled felt is as follows: fiber opening - carding - laying - pre-needling - main needling - felt - singeing - calender - impregnation -PTFE(water-repellent agent) drying - setting - rolling - rolling. The filter bag made of filter cloth after water and oil repellent treatment is used in the occasion of large moisture content, compared with ordinary filter bag, because the filter material is not easy to plug the paste bag, prolonging the cleaning cycle and the service life of filter bag. The flow of gas through is also increased, saving energy and maintenance costs, while also increasing production. In addition to the water-repellent and oil-repellent treatment of needled felt (such as polyester, polypropylene, anti-static, Metas), the finishing technology of our company can also be used for water-repellent and oil-repellent treatment of woven filter materials such as polyester 208 flan cloth and 729 tube cloth.

Polyester filter bag

Our company selects polyester high quality fine denier Dahua fiber, with advanced equipment to produce polyester (polyester) fiber needled filter felt, can mix a variety of fibers evenly and quantitatively, and then use multiple mixing cotton units and carding units to facilitate the lamination and gradient transformation of different fibers between the fiber network. In addition to the advantages of ordinary felt filters with high voidage, good permeability, high dust collection efficiency, long service life, etc., the product has a very good wear resistance due to its moderate temperature grade, instant up to 150 ° C, moderate acid and alkali resistance, so it is a variety of felt filters used in large quantities.

Polypropylene filter bag

Continuous operation at temperatures below 90 ° C, excellent acid and alkali resistance. It is used in the field of dust removal filtration and liquid filtration with flue gas temperature below 100℃ or strong acid and alkali. In terms of liquid filtration, polypropylene needle felt filter bags are usually used with plate and frame filter press, vacuum filter, bag filter, centrifugal filter and other liquid-solid separation equipment. It has the characteristics of good dimensional stability, high strength and long service life, so it also has the unique advantages of low resistance and easy cleaning. In mineral processing, coal preparation, petroleum, chemical and other industries, the need to filter small particles and ensure filtration occasions, polypropylene needle felt is far superior to the traditional woven filter material performance. Polypropylene needled filter felt is mainly used in the field of liquid-solid separation in metallurgy, mining, petroleum, chemical industry, chemical fiber, medicine, food and other industries.
