摘要
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。
Dissolving pulp is a kind of high purity pulp, which is mainly for the production of viscose fiber, nitration fiber, acetate fiber, cellophane, carboxymethyl cellulose and so on. ~here are two pulping methods for dissolving pulp. The first one is sulfurous pulping process, the another is prehydrolytic sulfate pulping process. Prehydrolysis sulfate pulping process is the method for producing artificial fiber pulp and other main technology with cellulose derivatives. The best raw materials for dissolving pulp are linters cotton, and lumber and non-lumber raw material also can be used to produce dissolving pulp, especially bamboo material attracted extensive attention.
