十八、羧甲基纤维素 1 生产情况 我国纤维素醚开发较晚,1958年二步法羧甲基纤维素(CMC)首先在上海赛璐珞厂试制投产,产量不足百吨,主要用于纺织工业上桨。60年代初,上海赛璐珞厂、苏州益民化工厂开发了低倍溶媒法生产工艺,上海青东化工厂等单位对水媒法工艺也做了改进与完善,其后全国各地也相继建立了许多CMC生产装
18. Production of carboxymethyl cellulose 1 The development of cellulose ether in China was relatively late. In 1958, the two-step carboxymethyl cellulose (CMC) was first trial-produced and put into production at the Shanghai Cellulose plant, and the production was less than 100 tons. It was mainly used in the textile industry. Paddle up. In the early 1960s, the Shanghai Saiqi Plant and Suzhou Yimin Chemical Plant developed the low-volume solvent production process. The Shanghai Qingdong Chemical Plant and other units also improved and improved the water-in-process process, and many subsequent establishments throughout the country have also been established.
