聚酰亚胺是阻燃的、耐温稳定的纤维，可持续在260°C温度使用，更高耐温可达280°C ;聚酰亚胺纤维滤料没有熔点温度，呈自然的金黄色; P84纤维是异型(三叶型)断面结构,具有很大的过滤表面积，有优异的过滤性能，所以P84纤维也经常被植入滤料表层(迎尘面侧以改 善滤料的过滤性能)。水泥窑炉、烘干、燃烧、冶炼、沥青搅拌、各类工业窑、燃煤锅炉的烟气净化中均可使用P84纤维除尘袋，尤其适用于排放浓度较高的工艺中。

Superior product - polyimide (PI/P84) dust bag

Polyimide is a flame-retardant, temperature-resistant and stable fiber that can be used continuously at a temperature of 260°C, and the maximum temperature resistance can reach 280°C; the polyimide fiber filter material has no melting point temperature and is naturally golden yellow.

P84 fiber has a special-shaped (trilobal) cross-section structure, has a large filtration surface area, and has excellent filtration performance, so P84 fiber is often implanted in the surface layer of the filter material (the side facing the dust to improve the filter performance of the filter material).

P84 fiber dust filter bags can be used in the flue gas purification of cement kilns, drying, combustion, smelting, asphalt mixing, various industrial kilns, and coal-fired boilers, especially for processes with high emission concentrations.
