According to customer’s demand or actual working condition demand to choose Nomex, Conex or domestic poly-aramid fiber as raw material, or even combine with PTFE scrim if necessary. The proper raw materials formulary make sure our product in excellent performance below 204°C, and Resistant 220°C momently. Application: Asphalt blending: high concentration of dust generating from the blending process of asphalt and sandstone compounds. After the blending finished, the dusted hot air need cleaned by bag filter. Iron and steel: dusted hot air purification of lime kiln, blast furnace gas, electric stove, torpedo car, converter and etc. Aluminums: high temperature dust air purification of recycled aluminums extractive. Cement industry: Flue Gas Cleaning of the raw material system. Carbon black :purification of dust air from reactor after cooling down to below 180°C. Coal-fueled furnace: high temperature dust air generated from mobile combustion furnace purification.
Raw material selects to produce Polyphenylene sulfide (PPS) fiber from America, Japan and domestic regions, this fiber is of very excellent chemical resistance, which almost resist all acid, alkali and organic solvent, except strong oxidizing agent, uses below 190°C, especially resist corrosion in SO2、SO3. Good hydrolysis resistance performance, although long time(500h)in temperature(160°C), high humidity(79%)conditions, no strength can be lost, easily use the occasion of moist flue gas. PPS fiber has powerful and full receptivity and inner chemical resistance, keeps favorable filter performance in harsh environment, and achieves the ideal lifetime. Application: PPS filter felt is an ideal filter material, such as pulse cleaning dust collector used in filter fire boiler (thermal power plant), garbage furnace, and dust treatment of fly ash in power plant.
The raw material are made in Austria Lensing Company, which produces polyimide fiber, the product name is P84. This fiber is different from synthetic fiber, the irregular leaf cross section forms very high fiber surface area, therefore, which is a small delivery head, and better filter effects. The main characters are thermal stability and non-combustibility. It resists acid and alkali, organic solvents and grease, limited oxygen index LOI value is 38, can be filtered hot gas below 260°C. Application: it can be slathered at bag type dusting of high temperature resistance industry, such as steel, metallurgy and waste incineration.
a kind of filter with high temperature resistance with 100% 5.0um glass chopped strand or other inorganic fibers with high temperature resistance through acupuncture treatment of non-woven process. The filter materials are not only the characteristics of high temperature resistance, corrosion resistance, stable dimension, low extension, heat shrinkage rate and high strength, but also the characteristics of three-dimensional microcellular structure, high porosity, low resistance, high deducting efficiency. Application: it is mainly used in Carbon black chemical industry, metallurgy of iron and steel, coal-fired boiler and other industrial high-temperature flue gas filtration.
Compared with glass fiber filter material, abrasion resistance, folding
Resistance and peel strength of FMS filter material has obviously increase. Compared with chemical fiber material, it has better dimension stability and overcomes the weakness of the high elongation of chemical fiber filter material. Due to cheaper than Nomex film laminating filter material, it becomes to be an ideal filter material and widely welcome by users. uses below 200℃，and Resistant 180 ℃. Applications: Steel, Smelting, Ferroalloy, Chemical, Cement, calcium, Carbide, Waste incineration, Electricity, Asphalt mixing, etc.
PTFE acupuncture filter felt is a more excellent performance non-woven filter material of new and high temperature. That is 100% 3D-5D PTFE curly fiber, by series of non-woven craft in loosing, combing, lapping and acupuncture, making dense acupuncture of micro pore in three dimensions, such as high temperature setting, singing, calendaring and coating process. This filter has three exclusive features: Temperature resistance Working environment of 250°C, instant temperature of 300°C. Chemical property PTFE filter material has good acid alkali resistance, is applied in complex exhaust gas treatment. Application: it is mainly used to purity harsh working condition dust air contain moist 、acid、alkali and oxide groups.
ance to liquids acids and bases, and corrosion- resistant.
