●Blended anti-static filter bag product introduction
Blended anti-static filter bag is an anti-static industrial dust filter bag made by mixing two or more fibers with different properties (such as polyester, PPS, aramid) with conductive fibers (such as carbon fiber, stainless steel fiber). While having good filtering performance, this product can effectively remove static electricity accumulated on the surface of the filter bag to prevent dust explosion caused by electric sparks, and is widely used in combustible dust places.
●Main structure and parameters
Project description
Base material polyester, PPS, aramid, acrylic, etc.
Anti-static fiber type conductive yarn, stainless steel fiber, carbon fiber
Continuous working temperature 120℃~190℃ (depending on the fiber combination)
Surface treatment singeing, calendering, laminating, waterproof and oil-proof, etc.
Filter bag form cylindrical, flat bag, star bag can be customized
●Product advantages of blended anti-static filter bag
1. Effectively prevent static electricity accumulation and ensure production safety
Contains conductive fibers to form a complete charge path, timely guide static electricity generated by dust friction, and avoid ignition sources from detonating combustible dust.
2. Adapt to various combustible dust working conditions
Applicable to working conditions with explosion risks such as coal powder, aluminum powder, flour, sugar powder, PVC powder, etc., in line with dust explosion safety standards (such as ATEX).
3. Combines filtering performance and chemical resistance
Select blended base fabrics (such as PPS/aramid blends) according to different working conditions, which can withstand high temperature, acid and alkali, humidity and heat, and maintain good dust removal effect.
4. High strength, wear resistance, long life
Adopting high-strength needle punching technology and composite fiber structure, the filter bag has strong tensile and bending strength, suitable for high-frequency pulse cleaning system.
5. Support personalized customization
Different functional combinations (oil-proof, waterproof, film-coated, high temperature resistant, encrypted structure, etc.) can be selected according to industry needs.
●Typical application scenarios
Coal powder preparation/conveying system
Aluminum-magnesium metal dust workshop
Flour, starch, feed processing plant
Chemical raw material (such as PVC, dye) production line
Powder coating, plastic additive manufacturing
Grain storage and transportation, powdered sugar packaging, food additive workshop
●Selection suggestions
If the dust is explosive → It is strongly recommended to use anti-static filter bag + grounded bag cage + explosion-proof system
If the temperature is higher than 160℃ → Aramid blended anti-static filter bag can be used
If the dust contains oil or moisture → It is recommended to add water-repellent and oil-proof or PTFE coating treatment

●FAQ:

Q. What working conditions are the blended anti-static filter bags suitable for?
A. Suitable for occasions with explosive dust, especially:
Coal powder, carbon powder conveying system
Aluminum magnesium dust grinding/polishing
Food processing such as flour, sugar powder, starch, feed, etc.
Chemical powder (PVC, dyes, additives, etc.)
Powder coating and plastic additive production

Q. What is the temperature tolerance range of the blended anti-static filter bags?
A. Depends on the base fabric material:
Polyester base fabric: continuous temperature resistance of 120℃, instantaneous 150℃
PPS blending: continuous temperature resistance of 160℃
Aramid blending: continuous temperature resistance of 190~200℃, suitable for high temperature occasions

Q. How to judge whether to use anti-static filter bags?
A. If any of the following conditions are met, anti-static filter bags must be used:
The dust is explosive (such as metal powder, coal powder, flour, etc.)
The dust particles are fine, easy to suspend and accumulate
The dust collector is a bag type or pulse bag filter
There are conditions on site that promote static electricity, such as friction, high wind speed, and dry gas
