摘　　要：以酚醛压塑粉为原料，用炭化法制备了平均孔径为 ０．３０～３．３μｍ、孔径分布狭窄、孔隙率为４０％～５５％的管状炭膜研究了原料粒度、成型压力、添加剂种类及含量等对膜的平均孔径和孔径分布的影响，测定了膜的水和Ｎ２通量，并用扫描电镜观察膜的形态结构结果表明，随着原料粒度的增加和成型压力的减小，炭膜的平均孔径增大，孔径分布变宽气体通量和水通量增大．添加剂对炭膜性能也有影响。将所制得的炭膜用于染料水处理。The microporous carbon membranes with average pore size of 0.3-3.3μm and porosity of 40%-55% were prepared by Pyrolysis of a commercially available phenol--formaldehyde novolac resin (PFNR). The effects of particle size of PFNR, molding pressure and additives on the characteristics of carbon membrane were investigated. The results indicated that the mean pore diameter, gas permeability and water flux of carbon membrane increase with increase of particle size of PFNR and decrease of molding pressure. Additives also affect the characteristic of carbon membrane. The carbon membrane prepared is effective to treat the wastewater of dye.
