摘要
对二氧化氯漂白棉浆的生产工艺进行了研究。探讨了影响二氧化氯漂白过程的主要因素,通过单因素试验及正交试验,并结合公司实际流程情况及生产成本,确定了高黏浆生产的ClO2漂白工艺参数为:浆浓为5%,漂白温度为50℃,ClO2用量为9kg/t浆,漂白pH为3.0,漂白时间为90min。该漂白工艺结合公司现有双氧水漂白,生产的高黏棉浆白度≥85%,黏度≥1750ml/g。
The technology of chlorine dioxide bleaching for cotton pulp was studied.The main factors influencing the bleaching process of chlorine dioxide were discussed.The results show that the optimal conditions of chlorine dioxide bleaching for high viscosity cotton pulp are as follows:pulp consistency 5%,the bleaching temperature 50℃,chlorine dioxide dosage 9 kg/t pulp,the bleaching pH 3.0 and the bleaching time 90 min.The bleaching conditions were studied by single factor experiment and orthogonal experiment method,practical production situation of the company and production costs.Combination of chlorine dioxide bleaching and hydrogen peroxide bleaching for high viscosity pulp production,the whiteness can reach over(or equal to)85%with viscosity over(or equal to)1750 ml/g.
