摘要
Abstract
In this study,four types of ultrafine fiber composite filter papers were prepared via wet-forming technology using glass fibers,polyethylene terephthalate(PET)fibers,fibrillated tencel fibers,and fibrillated aramid fibers as main raw materials.Their oil-gas separation performances under room-temperature and high-temperature conditions were systematically evaluated.The results showed that as the operat-ing condition changed from room temperature to high temperature,the most penetrating particle size(MPPS)of four types of ultrafine fiber composite filter papers increased from 0.20 μm to 0.30～0.40 μm,their steady-state pressure drop decreased by 600～1 100 Pa,and the filtra-tion efficiency for droplets with particle size of 0.2～10 μm decreased by 0.2～7 percentage points.In addition,under high-temperature condi-tions,the introduction of fibrillated fibers could improve the steady-state pressure drop and quality factor of ultrafine fiber composite filter pa-pers.Among them,the ultrafine fiber composite filter paper prepared by blending with fibrillated aramid fibers exhibited a superior steady-state pressure drop(4 450 Pa)compared with the commercial filter paper(4 700 Pa),and its quality factor(0.480 kPa-1)was 1.2 times that of the commercial filter paper,demonstrating promising application potential in high-temperature environments.关键词
