Electrostatic polyester needle felt dust bag
The electrostatic polyester needled felt dust bag is the main filter material in the bag filter. The non-woven needle punching process is used to card and spread the polyester staple fiber on a thin fiber cloth with staggered fibers and uniform gap distribution and then needle punched into a felt.This filter material has high strength, good elastic recovery performance, stable fabric size, good performance, large porosity, good air permeability, long service life, good dust removal effect, and good mechanical properties at room temperature (below 130°C). Electrostatic polyester cloth bags are made of conductive fiber base fabric, needle punching polyester on both sides, or mixed guide fiber andpolyester fiber mixed needle punching on both sides of the base fabric.The filter material has good electrical conductivity and high air permeability. After singeing, calendering and microwave shaping, the bag does not shrink at an instant high temperature, and the dust-facing surface is flat and smooth, with high strength and strong corrosion resistance. It is a common material suitable for filtering explosive dust.
Electrostatic polyester needle-punched felt dust bag has the characteristics of high porosity, good air permeability, dust collection and long service life that are unique to ordinary felt filter cloth, and it is also moderately resistant to temperature, acid and alkali.In addition to the process of producing ordinary needle-punched felt dust-removing cloth bags, polyester cloth bags also require conductive fiber yarns to be incorporated in the warp yarns of the base fabric for needle-punched felt production, or conductive fibers or conductive materials mixed in chemical fibers. It is applied to the dust removal and filtration of explosive industrial dust. The dust collection bag is especially suitable for blast furnace gas, coal mill dust collection, cement plant coal mill dust collection and explosion-proof dust collection in other industries. It is the ideal choice of dust removal accessories for explosion-proof dust collection.
