毛竹硫酸盐法蒸煮及其全无氯漂白浆的特性
Kraft Pulping and TCF Bleaching Performances of Phyllostachys Pubescens Stem
摘要
Abstract
Bamboo is commonly used as a raw material at some of pulp mills. In this study, Phyllostachys pubescent obtained from Xiaohe-shan, Hangzhou was chemically analyzed, cooked with kraft process and bleached with totally chlorine-free (TCF) bleaching. In addition, P. Pubescent stem was compared with Hibiscus cannabinus bast, Cryptomeria japonica D. Don wood and Eucalyptus grandis wood. The lignin content of P. Pubescens stem is similar to that of E. Grandis wood and the xylan content of P. Pubescent is higher compared with the others. In kraft cooking, the delignification rate of P. Pubescens is equal to that of E. Grandis and better than that of H, cannabinus bast. However, in a given kappa number the pulp yield of P. Pubescens is lower than that of both E. Gradis and H. Cannabinus bast and is equal to that of C. Japonica. The hexenuronic acid content of P. Pubescens kraft pulp is lower than that of H. Cannabinus bast and E. Grandis. The brightness of unbleached pulp prepared from P. Pubescens is much higher than that from H. Cannabinus and E. Gradis. The P. Pubescens pulp has higher brightness after oxygen bleaching than the pulps of the H. Cannabinus and E. Grandis.关键词
