What are the functions of mixed conductive fiber - antistatic filter bags?

Mixed Conductive Fiber - Antistatic Filter Bags are specially designed industrial filter materials. By blending conductive fibers (such as carbon fibers, stainless steel fibers, or conductive polymer fibers) into ordinary filter bag fibers, these materials possess antistatic, explosion-proof, and highly efficient filtration properties. They are primarily used in dust filtration environments prone to static electricity, preventing static electricity accumulation from causing explosions or affecting filtration performance.

1. Basic Structure and Function

Base Fiber: Typically, conventional filter fibers such as polyester (PET), polypropylene (PP), and PPS (high-temperature resistant) are used to provide basic filtration.

Conductive Fiber: Carbon-based fibers, metal fibers (such as stainless steel), or conductive polymer fibers (such as polyaniline) are evenly blended to form a conductive network that quickly conducts away static charges.

Blending Method:

Uniform Blending: Conductive fibers are evenly interwoven with ordinary fibers, resulting in overall conductivity.

Gradient Distribution: The outer layer contains more conductive fibers, enhancing the surface's antistatic properties.

2. The role of mixed conductive fiber-antistatic filter bags

Anti-static/Anti-deflagration

Eliminating static sparks: When filtering dust (such as chemical, coal, and metal powders), fiber friction can easily cause static electricity to accumulate, potentially leading to explosions or fires. Blended conductive fibers (such as carbon fibers and metal fibers) form a conductive network that quickly conducts static charge away, preventing spark discharges.

Suitable for flammable and explosive environments: Meets explosion-proof standards such as OSHA and ATEX, making it suitable for high-risk environments such as the petroleum, pharmaceutical, and grain processing industries.

High-efficiency filtration

Maintaining filtration performance: When conductive fibers are blended with conventional fibers (such as polyester and polypropylene), they retain the original filter bag's filtration accuracy (capturing micron-sized particles) while imparting anti-static properties.

Reducing clogging: After eliminating static electricity, dust is less likely to adhere to the filter bag surface, reducing the risk of bag sticking and extending cleaning cycles.

Extending filter bag life

Reducing static damage: Static electricity accumulation can cause the fiber structure to loosen or break down. Conductive fibers prevent charge accumulation and slow material aging. More Thorough Cleaning: After static electricity is eliminated, pulse backflushing improves cleaning effectiveness and prevents residual dust from accumulating.

Safety Protection

Equipment Protection: Electrostatic discharge can damage electronic equipment (such as sensors and control systems). Conductive fibers prevent such interference.

Personnel Safety: Workers are protected from static shock when touching the filter bags.

Adaptability to Complex Working Conditions

High Humidity Environments: Ordinary filter bags may temporarily lose static electricity in humid environments, but the blended conductive fibers offer more stable anti-static performance.
