溶解浆是高纯度的精制浆,可用于生产黏胶纤维、硝化纤维、醋酸纤维、玻璃纸、羧甲基纤维素等产品。制备溶解浆的方法分为两种:一种是亚硫酸盐法,另一种是预水解硫酸盐法。制备人造纤维浆粕和其他纤维素衍生物用浆主要工艺为预水解硫酸盐法;制备溶解浆的最佳原料为棉短绒,也可以用木材和非木材原料,目前竹纤维原料受到广泛关注。 Dissoluble pulp is high purity refined pulp, can be used for the production of viscose fibers, nitrocellulose, acetate, cellophane, carboxymethyl cellulose and other products. There are two ways to prepare dissolving slurries: one is the sulphite process and the other is the prehydrolysis sulphate process. The main process for preparing man-made fiber pulp and other cellulose derivatives pulp is prehydrolysis sulfate method; the best raw material for preparing dissolving pulp is linters, and wood and non-wood raw materials can also be used. At present, bamboo fiber raw materials are widely concerned .
