Description

PPS bags are made of ***polyphenylene sulfide fibers, processed through a combination of three-dimensional high-density needle-punching and PTFE impregnation. They maintain a ≤1% thermal shrinkage rate even in 180℃ coal flue gas. The uniformly coated surface achieves an initial filtration efficiency of 99.999%, nearly eliminating emissions of 0.3μm fine particles. After 72 hours of acid and alkali immersion testing, the strength retention rate is >90%, effectively resisting corrosion from complex gases like SOx, NOx, and HF. Paired with a pulse cleaning system, the online cleaning pressure is as low as 0.3MPa, and the operating pressure difference is consistently maintained at around 800Pa, reducing energy consumption by 25% compared to conventional filter bags. With a total lifespan exceeding 30,000 hours, they are widely used in high-temperature and high-corrosion environments in power plants, cement, steel mills, and more, truly representing energy-saving and long-lasting filter material.

As the exhaust temperature of the incinerator suddenly rises to 190°C, the PPS filter bags firmly maintain the dust removal line with their instantaneous temperature resistance threshold of 190°C; their glass fiber transformation temperature reaches up to 215°C, remaining non-melting and non-shrinking even in the face of sudden sparks; reinforced with PTFE scrim, the tensile strength in both warp and weft directions is ≥900N and 1200N respectively, capable of withstanding the combined erosion of high humidity, high oxygen content, and acidic gases; the coated surface facilitates easier dust removal, extending the cleaning cycle by 30% and simultaneously reducing the energy consumption of the fan motor; over a continuous three-year operation, the emission concentration has consistently been ≤5mg/Nm3, providing an efficient, stable, and environmentally friendly dust control solution for urban solid waste disposal.

The production process of PPS bag involves multiple stages, including fiber preparation, spinning, weaving, and post-treatment. High-quality PPS fibers are selected as raw materials, which are then processed into a uniform fiber web through steps like opening and combing. Next, the fiber layer is reinforced using needle-punching or hydroentanglement techniques to form a base fabric with certain thickness and strength. During weaving, the fabric's filtering accuracy and breathability are enhanced by adjusting the warp and weft density and fabric structure. Post-treatment may include heat setting, singeing, or coating to further improve the bag's stability and performance. The entire production process requires strict control of parameters such as temperature, speed, and tension to ensure consistent product quality.
