摘要: 介绍了采用单螺杆挤出法,通过改变活性炭与超高相对分子质量聚乙烯(PE-UHMW)的质量含量比例和不同相对分子质量的PE-UHMW,制备活性炭/ PE-UHMW微孔管材;并采用SEM和压汞仪分析了微孔管材的微孔结构和参数,同时还测试了微孔管材的密度和压缩强度。结果表明:PE-UHMW有助于活性炭的挤出,但若其含量过高,很容易将活性炭包覆起来堵塞微孔;采用单螺杆挤出法制备活性微/PE-UHMW孔管材,其微孔孔径和开孔率可与传统烧结成型法制备的微孔管材相媲美;微孔管材的密度和压缩强度随组分中的PE-UHMW的相对分子质量的增大而增大,随PE-UHMW含量的增大而减小。

Abstract: Employing single screw extrusion, by changing the quality content and the types of the ultra-high molecular weight polyethylene (PE-UHMW), prepared the activated carbon / PE-UHMW microporous tubing; what is more, using SEM and mercury porosimetry analyzed the microporous structure and parameters of the microporous tubing, also tested microporous tubing s density and compressive strength was introduced. As the results shows, PE-UHMW contributes to the extrusion of activated carbon, but it is easily wrap the active carbon and clog the micro porous when its content is too high;The microporous materials, prepared by single screw extrusion and sintering, have similar pore size and porosity;With the increase of PE-UHMW’s molecular weight, the density and compressive strength of the microporous materials increase; with the increase of PE-UHMW’s content, the density and compressive strength of the microporous materials decrease.

Key words: ultra-high molecular weight polyethylene;active carbon, extrusion;microporous piping
