摘要:本研究以玻璃纤维、聚对苯二甲酸乙二醇酯纤维（PET纤维）、原纤化天丝纤维、原纤化芳纶纤维为主要原料，采用湿法成形技术分别制备了4种超细纤维复合滤纸，系统评估了其在常温和高温工况下的油气分离性能。结果表明，随着运行条件由常温工况转变为高温工况，4种超细纤维复合滤纸的最易穿透粒径均由0.20 μm增大至0.30~0.40 μm，其稳态压降降低600~1 100 Pa，对粒径0.2~10 μm液滴的过滤效率下降0.2~7个百分点。此外，针对高温工况，原纤化纤维的引入可以改善超细纤维复合滤纸的稳态压降和品质因子。其中，配抄原纤化芳纶纤维制得的超细纤维复合滤纸的稳态压降（4 450 Pa）优于商品滤纸（4 700 Pa），且品质因子（0.480 kPa-1）是商品滤纸的1.2倍，展现了其在高温工况中良好的应用潜力。
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 operating 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 filtration efficiency for droplets with particle size of 0.2~10 μm decreased by 0.2~7 percentage points. In addition， under high-temperature conditions， the introduction of fibrillated fibers could improve the steady-state pressure drop and quality factor of ultrafine fiber composite filter papers. 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.
