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.

Antistatic Treatment

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.
