在当今液压工业对油液的过滤要求越来越重视的情况下 ,研制高精度、大纳污容量的过滤材料成为非常重要的课题之一 ,因用干法制造的纤维滤材 ,设备昂贵 ,工艺过程较复杂 ,不易控制 ;而湿法制造滤材 ,原料来源广泛 ,价格低 ,并具有较高的过滤性质 ,因此被广泛地应用。中国矿业大? In today’s hydraulic industry, oil filtration needs more and more attention, the development of high-precision, large capacity of the filter capacity of pollutants to become one of the most important issues, due to the use of dry fiber filter media, equipment, expensive, The process is complicated and difficult to control. The wet filter media, which has wide sources of raw materials, low prices and high filtration properties, are widely used. China Mining big?
