高温环保复合过滤材料研发及应用

以研发高温环保复合过滤材料为目标,选用耐高温、耐腐蚀、抗氧化的纤维为原料,采用针刺-水刺复合工艺,提高了高温环保复合过滤材料的微细粒子(PM2.5)的捕集效果,同时防止了细微粉尘进入过滤材料深层。迎尘面采用水刺层,具有表面过滤和利于清灰的作用,使表面对细微粉尘的过滤更加高效、可靠,并降低了过滤阻力。复合技术的应用还显著改善了过滤材料的耐温性能,并使其耐腐蚀性、抗氧化性和拉伸强力等显著提高,同时降低了生产成本。

Development and application of high-temperature environmental protection filter material compound products

With the aim to research and develop high-temperature environmental protection com-pound filter materials, the high-temperature, corrosin-resistant and antioxidant fibers were chosen as raw materials, with needle-punch and spunlace compound technology, the trapping effect of micro-particles(PM2. 5) of the compound materials was increased, and the fine dust from penetrating into the deep filter was prevented. The dust facing surface was made of spunlaced layer, which possessed the effect of surface filtration and was conducive to clear ash, and therefore, surface filtration was more efficient and reliable, and the filtration resistance was also reduced. The application of com-pound technology significantly improved the temperature resistance of the filter material, and the cor-rosion resistance, oxidation resistance and tensile strength of the filter material were increased great-ly, and the cost was reduced.
