针刺和水刺复合工艺制备的 PPS 滤料及其性能研究

摘要

The production process of needle-punching combined with spunlacing on manufacture PPS filter media used in flue coal fire plant was presented .The filtration material be compared on normal needle-punched PPS filter media, and test on the area density, strength, permeability, surface plainness, filtration efficiency and filtration accuracy.The test result was that the comprehensive performance of PPS filter media composed by process of needle-punching and spunlacing was better than that of normal needle-punched PPS filter media.%　　介绍了制作燃煤电厂烟气过滤用PPS滤料的针刺和水刺复合新工艺，并与普通针刺PPS滤料相比较，进行面密度、强力、透气性、表面平整度、过滤效率和过滤精度等性能测试。结果表明，针刺和水刺复合工艺制备的PPS滤料的综合性能优于普通针刺PPS滤料。
