Study on the Process Conditions of Bamboo Dissolving Pulp Preparation
摘要
Abstract
The bamboo pulp was prepared from mixed bamboo slices by pre-hydrolysis,alkali solution neutralization,kraft cooking and ECF bleaching.To obtain the best conditions for the preparation of bamboo pulp,the performance of the slurry was analyzed by changing the maximum temperature of the pre-hydrolysis,the amount of alkali in the alkaline solution neutralization and the maximum temperature and amount of alkali in kraft cooking.The results showed that the best performance indicators of bleached bamboo pulp was obtained when the maximum temperature of pre-hydrolysis was 165℃,the alkali content was 8% ~ 10% (Na2O),the maximum temperature and the amount of alkali correspond to 165℃ and 6% (Na2O) in kraft cooking,respectively.When the maximum temperature of pre-hydrolysis and the maximum cooking temperature of KP were 145℃,the yield of pulp was 6% ~ 7% higher than that of the maximum temperature of pre-hydrolysis (165℃)and the maximum cooking temperature of kraft cooking (145℃).The bamboo pulp after bleaching could be used to prepare cellulose acetate and viscose fibers when the amount of alkali was 6% to 8% (Na2O) and 10% to 12% (Na2O) in the kraft cooking,respectively.关键词
