2026年9月14日
Abstract: High-temperature filtration materials are the core component of baghouse dust collection technology and play a critical role in reducing particulate matter emissions from flue gas in industries such as thermal power generation, iron and steel smelting, cement and building materials, and waste incineration. Starting from fiber raw materials, this paper reviews the performance characteristics and modification strategies of organic fibers, including polyphenylene sulfide (PPS), polyimide (PI), and aramid fibers, as well as inorganic fibers such as basalt fibers and glass fibers. The advantages and applicable scenarios of fabrication technologies, including needle punching, hydroentangling, and electrospinning, are analyzed, together with the effects of finishing technologies such as coating, membrane lamination, and sol impregnation on improving filtration accuracy, chemical corrosion resistance, self-cleaning performance, and other properties of filter media. On this basis, future development should focus on developing novel fiber systems, strengthening multi-technology coupled processes, addressing interfacial failure, and expanding synergistic pollution-control functions. Meanwhile, greater attention should be paid to the trends of green manufacturing and digital transformation, providing a reference for the development and application of high-performance filtration materials for high-temperature environments.
