Nonwoven Needle Felt Dust Nomex Filter Bag/Filter Sleeve for Baghouse
Product Description
Nomex filter bag has the properties of anti hydrolysis, anti-oxidation, acid and alkali resistance. Nomex needle punched filter felt is used in high temperature and harsh environment, and its mechanical and chemical properties are extremely stable. It can achieve ideal service effect and service life at high temperature. Nomex needle punched felt is made of the fibers produced by teiren company of Japan and combined needle punched in a certain proportion.
Nomex filter bags are widely used for ventilation, dust removal and material recovery in coal-fired power plants, coal chemical industry, waste incineration, asphalt mixing plants, metallurgy, chemical industry, cement and other high-temperature flue gas industries.

Post-treatment introduction
Burning and Pressing Treatment
The imported burning and pressing equipment and the treated needle felt filter material has the unparalleled advantages of ordinary singeing and calendering treatment on one side and double side, which not only improves the cleaning performance of the filter material, but also meets the collection of fine dust.
Some dusts will burn when it encounters a spark at a specific concentration. Therefore, anti-static treated needled felt filter media should be used for flammable and explosive dust. Antistatic filter material refers to mixing conductive fiber (including binary conductive fiber, graphite conductive fiber and stainless steel conductive fiber) into the filter material fiber, so that the whole filter material has conductive properties.
Water-Proof and Oil-Proof Treatment
The oil-proof and water-proof treatment of fluorocarbon resin and PTFE impregnation is adopted for the needled felt filter material, which is easier to collect dust on the surface of the filter bag of wet dust containing gas (especially for water-absorbing and deliquescent dust), avoiding and reducing the phenomenon of pasting bag.
PTFE Membrane Treatment
When the particle size of dust is less than 1 micron, or the dust has a large viscosity, or the humidity of the gas is large, the ordinary filter material can not effectively filter. The membrane filter material made of polytetrafluoroethylene (Teflon®) has high filtration precision, smooth surface, no adhesion to dust. It’s easy to clean dust and the dust does not penetrate into the filter material achieving surface filtration.
Can be widely used in the field of high temperature filtration, long-term use can maintain high strength and high performance; used in asphalt, cement, steel, non-ferrous metals, lime, dust, metallurgy, drying, gravel, gypsum, plastic, carbon black, coke, Shipbuilding, tobacco and other industries.
The High Filtration Nomex /Aramid Dust Filter Bag in Steel Industry Packaging:
Different types of bag filter cloth sock sleeves must be individually packaged. In general, it is wrapped in plastic bags for water proof, then put in a carton. stainless steel snap band Filter bag with the diameter of cell plate 135mm must be neat and regular packing, with the ring of the filter bag(whatever stainless steel or carbon material) to avoid ring flat compression deformation. For the requirement to keep the shape of filter bag, it must fill padding for filter bag inside. Any other packing ways also be accepted up to you.
