Blended anti-static cloth bag

Blended bag is a type of filter bag used for industrial dust removal. It achieves its function by mixing conductive fibers into the fibers, which can prevent dangerous situations such as dust explosions.

Material and Structure

Substrate fibers: Polyester fibers, polyamide fibers, and other materials are usually used as the main substrates, which have good physical properties such as. Some products may also be mixed with linen, fiberglass, etc. to enhance the overall performance of the cloth bag.

Conductive fiber: Carbon black fiber, stainless steel fiber, or composite conductive fiber are commonly used. The blended dust removal bag of Botou Yiheng Dust Removal Equipment Co., Ltd. is made of 85% polyester fiber as the skeleton and blended with 15% high conductivity carbon black fiber. These conductive fibers form a three-dimensional conductive network in the cloth bag, and static electricity can be conducted.

Surface coating: Some blended cloth bags are coated with a composite coating of tin antimony oxide (ATO) nano conductive particles and silicon hydrophobic agents to further enhance their conductivity and dust cleaning performance.

Performance Characteristics

Excellent performance: The surface resistivity is usually stable at 10 ⁶ -10 ⁸ Ω, which can instantly discharge frictional static electricity, avoid static electricity accumulation, and reduce the risk of dust explosion.

Good dust cleaning performance: Some bag surfaces are formed with honeycomb like protrusions through laser engraving technology, and fluorinated polymers and nano silica particle coatings are added to make the dust contact angle>160 °, reducing the surface energy to 22mN/m. The detachment rate of viscous dust during pulse cleaning can be increased by 90%.

Good temperature resistance: The long-term working temperature is generally between 130-150 ℃, and it can withstand an instantaneous high temperature of 160 ℃. The material structure is stable and not easily deformed at high temperatures.

Superior physical performance: formed by needle punching process, with three-dimensional interlaced fibers, tight structure, tensile strength, suitable for high air to cloth ratio dust removal systems. Some products, after processing, can cope with general acidic and alkaline gas environments.

application

Mainly used for dust collection occasions with explosion risks, such as blast furnace gas dust removal and converter flue gas purification in steel smelting, coal powder boiler dust removal and coal transportation system dust control in the power industry, dust recovery in industries such as plastics, pesticides, and coatings in chemical production, and explosive dust capture in colored metal processing.

Product advantages

The skeleton of the blended cloth bag adopts a composite weaving technology of glass fiber and stainless steel wire, which is resistant to tension and has a small deformation rate during pulse vibration. Metallic conductive rings are implanted at the interface of the filter bag, ensuring continuity of resistance between the bag and the flower plate holes. Its modular design supports online replacement of single cloth bags, which can shorten maintenance time and reduce equipment downtime losses.
