Chemical raw materials, due to their flammable and explosive nature, have extremely strict transportation requirements and are expensive. To ensure safety and reduce costs, conductive and permanently anti-static bulk bags are widely used to package these hazardous materials. These bags incorporate conductive threads, such as polypropylene or polyethylene fibers, to dissipate static electricity generated by friction, preventing the contents from igniting fires or explosions.
Static charge is primarily generated by friction between fibers. Conventional bulk bags inevitably generate static electricity during loading and unloading, posing a safety hazard. To address this issue, conductive bulk bags are designed with conductive threads distributed throughout the bag body, straps, loading and unloading ports, and seams, forming a conductive network. These threads are spaced less than 5 cm apart, resulting in a surface resistance of less than 10 ohms, effectively preventing static electricity accumulation and improving safety.
The improved low-static bulk bag further enhances performance. By weaving conductive fibers in parallel, spaced intervals throughout the woven fabric, static electricity can be naturally discharged without grounding, significantly simplifying handling. Additionally, a discharge tube and lifting lugs are added for convenience. The low-static fiber's long-lasting conductivity makes these bags reliable and safe in explosive and hazardous environments, making them suitable for packaging powders and viscous materials.
Overall, conductive and low-static bulk bags, through optimized design, effectively prevent the hazards associated with static electricity, reduce transportation costs, and provide a safe solution for the storage and transportation of hazardous chemicals.
Conductive bulk bags achieve electrical conductivity through grounding of conductive threads woven into the bag fabric and straps. They effectively dissipate static electricity generated during loading and unloading, preventing combustion and explosion. They are primarily used for packaging hazardous materials in the chemical, pharmaceutical, and other industries.
