微波辐射硫酸盐-蒽醌法麦草制浆研究

摘要

密闭条件下用微波辐射进行麦草硫酸盐蒽醌法制浆,通过不同药品用量、液比和微波功率的单因素实验.当用碱量为14％、硫化度为2％、液比1∶7、功率450 W时,纸浆得率在50.08％,卡伯值在18.19左右.实验为微波辐射用于传统制浆工艺奠定了一定的实践基础.%This paper studied the sodium sulfide pulping of wheat straw with microwave radiation in obturation circumstance, the results showed that the yeild of paper pulp is about 50.08% and Kappa number is about 18.19 when the ratio was dosage of sodium hydroxide 14% , sodium sulfide 2% ,liquid ratio of 1:7, power 450 W by one-factor experiment. To some extent, this research provides the pratical basis for the microwave radiation used in conventional pulping processes.
