摘要： 经40%酚醛树脂处理的中密度板样品炭化物简称木陶瓷(WCS),是一种低成本而性能优异的新型多孔炭材料;添加阻燃剂及20%酚醛树脂处理的中密度板样品炭化物简称P-木陶瓷(P-WCS)。本研究采用低温氮吸附法对比木炭研究了木陶瓷的孔隙结构。结果表明,由于样品未经活化,因而吸附能力较差,且以木炭为最差。木陶瓷的微孔面积为314.16m2/g,微孔容积为0.1262mL/g,大于P-WCS,且远远大于木炭。木陶瓷的平均孔径为1.598nm,小于P-木陶瓷,远远小于木炭。说明酚醛树脂为木陶瓷引入了较多的微孔,使其吸附性能远高于传统的木炭。

Abstract: Woodceramics(WCS) is a new porous carbon material of low cost and excellent properties,which is obtained by carbonization of middle density fiberboard impregnated with 40% PF resin.Pore structure was measured by low temperature N2 absorption method.Woodceramics which is obtained by carbonization of middle density fiberboard impregnated with fireretardant and 20% PF resin is called P-WCS.Results showed that adsorption properties of traditional charcoal were very poor because of not being activated.Micropore area of WCS was 314.16 m2/g,and micropore volume was 0.126 2 mL/g,which are much more than those of charcoal.Average diameter of WCS was 1.598 nm,which is much less than that of charcoal.PF resin brought lots of micropores into the woodceramics to have adsorption properties much better than those of charcoal.

Key words: woodceramics(WCS), pore structure, charcoal
