Anti-static polyester felt cloth bag

Product introduction

Antistatic polyester felt cloth bag is formed by dipping, prebaking and baking needling Ni with hydrophobic agent and oil repellent. After drying, the hydrophobic agent and the oil repellent are attached to the surface of the filter material fiber with a mesh package, thus reducing the surface tension between water and oil and the filter bag, so that the wet filter medium formed by water, oil and dust will not adhere to the surface of the filter bag, thus avoiding the paste bag phenomenon.

Product characteristics

1.Filter material strength, elastic recovery performance is good, fabric size stability, good wear resistance, porosity, good breathable performance, long service life,

2. Polyester is cheap, so polyester needled felt dust bag is a more cost-effective filter medium at low temperature;

3. Polyester needled felt is a fine staple fiber filter with staggered arrangement and uniform pore distribution. Its porosity reaches 70%, twice that of woven filter cloth.

4.Good dust removal effect, normal temperature (below 130℃) has good mechanical properties and acid and alkali resistance

5.The surface of polyester needled felt is hot rolled, burnt or coated, smooth and smooth, not easy to clog, no deformation, easy to clean, long service life.

6.The anti-static needle felt has the function of anti-corrosion to stop the electrostatic discharge of the blast furnace gas and the dust collection of the coal mill bag in the cement plant, and the function of generating static electricity.
