在现代汽车行业,往往需要高温和高压,相应地要求有耐高温、耐高压的过滤与分离材料。为保证汽车与液压系统安全可靠地工作,各种油类与工作气体要进行严格的精过滤,通常的塑料多孔材料虽然可以用球形颗粒做成,并具有很好的过滤性能,但工作温度一般不超过100℃,而且强度低,只适用于低压的工作条件。多孔陶瓷、玻璃等材料由于性脆、抗热震和透过性能差且不能焊接等原因也大大限制了它的应用。各种编织
In the modern automotive industry, high temperatures and pressures are often required, with correspondingly high temperature, high pressure filtration and separation materials. In order to ensure the safe operation of the automobile and hydraulic system, all kinds of oil and working gas must be strictly fine-filtrated. Although the usual plastic porous material can be made of spherical particles and has good filtration performance, the working temperature is generally Not more than 100 ℃, but low strength, only suitable for low pressure working conditions. Porous ceramics, glass and other materials due to sexual crisp, thermal shock resistance and poor permeability and can not be welded and other reasons also greatly limits its application.
