We usually refer to the dust bag filter material less than 130C as the normal temperature filter material. At present, the following types are commonly found in the market.

  • Polyester Dust Bag, Polyester Dust Bag:

It belongs to the normal temperature dust bag. It adopts the non-woven acupuncture process to use the fibers staggered and the fine fiber cloth with uniform void distribution. After layer treatment, the surface is smooth and smooth, and it is not easy to be blocked by dust. This filter material has a large porosity and good air permeability. The product has strong chemical resistance and can not only filter normal temperature gas, but also filter corrosive gas containing acid and alkali, and filter water and oil. It is an ideal filter material for liquid-solid separation and other fields under normal temperature conditions. Polyester needle-punched felt filter material can be used for a long time at a temperature below 120C. It has the advantages of acid resistance, good air permeability, high dust removal and purification efficiency, and is suitable for filtering abrasive dust such as clay, cement clinker, limestone, etc.

  • Blended Dust Bag:

It is a normal temperature dust removal bag, which usually has an industrial dust concentration of up to

At the time of explosion (i.e., explosion), if it encounters factors such as electrostatic discharge sparks or external ignition, it is easy to cause

Explosion and fire. Such as: surface dust, chemical dust, explosive dust, etc. In the case of electrostatic discharge, there is a possibility of explosion. In the field of bag dust removal, if these dusts need to be collected by cloth bags, the cloth bags themselves are required to have functions. In addition to the production of ordinary needle felt, the production of filter materials also It is required to incorporate conductive fiber yarns into the base fabric warp yarns for producing needled felts or to incorporate conductive fibers into chemical fibers.

  • Acrylic Dust Bag:

It belongs to the normal temperature type of dust removal bag. It adopts the non-woven needle punching process and uses the strong acrylic fibers to stagger and arrange the fine fiber cloth with evenly distributed voids. This filter material has large voids, good air permeability and strong chemical resistance. It can not only filter normal temperature gas, but also filter medium temperature gas (150C) and is an ideal filter material for acid and alkali corrosive gas conditions.

  • Three-Proof Dust Bag:

It belongs to the normal temperature dust bag. The needled felt combines the advantages of the two types of needled felts. Compared with ordinary filter materials, it not only has moisture-proof properties, but also has the best effect.

  • Dust Bag:

Needle-punched filter felt is a kind of dust bag at room temperature. Needle-punched felt can prevent water and various oil contaminants from adhering and infiltrating. Compared with ordinary filter materials, it not only has characteristics, but also has anti-caking and peeling resistance to dust. sex.
