Product Description
Why Use Antistatic Filter Bags?
When the concentration of industrial dust reaches a certain level (that is, the explosion limit), if it encounters electrostatic discharge sparks or external ignition, it will easily cause explosion and fire. Such as: flour dust, chemical dust, coal dust, etc. may explode in case of electrostatic discharge. In the field of bag dust removal, if the dust needs to be collected with a cloth bag, the filter material for making the dust bag is required to have anti static properties. The anti-static filter bags are all made of anti-static needle-punched felt, which has excellent anti-static performance and is the most ideal choice for explosion-proof dust collection.
Antistatic Principle of Anti-static Filter Bags
Conductive fibers or stainless steel conductive materials are mixed into the chemical fibers used to produce needle felt to produce antistatic needle felt with excellent antistatic properties. The results of comparing antistatic dust filter bags with ordinary dust filter bags in terms of physical properties, charge and dust removal efficiency have confirmed the superiority of antistatic dust filter bags.
Anti-static filter bags have the following characteristics
- Conductive fibers are not affected by the environment.
- When the fabric is charged, it discharges through its own weak corona and leaks to the ground.
- When weaving, long filaments are used for warp yarns and short filaments are used for weft yarns.
Main Type of Anti-static Filter Bags
| Material | Conductivity | Temperature Resistance | Chemical Resistance | Abrasion Resistance | Durability |
| Polyester (PET) with Conductive Fibers | High | Up to 150°C (302°F) | Good | High | High |
| Polypropylene (PP) with Conductive Fibers | High | Up to 90*C (194°F) | Excellent | Moderate | Moderate |
| Polyimide (P84) | Moderate | Up to 260*C (500°F) | Very Good | High | High |
| PTFE (Polytetrafluoroethylene) | High | Up to 250*C (482°F) | Excellent | High | High |
| Aramid (Nomex) | Moderate | Up to 200*C (392°F) | Good | High | High |
We Pay Attention to Every Processing Detail:
- Accurately design the size of the filter cloth required for the filter bag. The filter cloth will be larger than the actual design size to leave enough operating space.
- Choose the right filter bag accessories and check their quality.
- We draw, cut and sew the filter bags on an automatic production line. When the filter bag needs to be processed manually, we open it on the operating platform and use a certain pulling force to keep it flat.
- We maintain strict processing quality standards in accordance with design drawings and operating procedures. Our workers dress in compliance with safe construction requirements and are prohibited from smoking.
