当前变性淀粉浆料使用中几个问题的探讨

Discussion of Some Problems on Using Modified Starch Size

针对当前国内纺织厂在使用变性淀粉浆料中出现的一些问题以及某些与生产实际相背的误导,从淀粉的化学基本结构与变性的基本原理出发作了分析。指出了当前常用的变性淀粉浆料各自的适应性与使用时的注意点,特别是CMS中的NaCl、磷酸酯淀粉的适应性、以及干法生产与湿法生产商品的优缺点比较等,希望能为纺织厂用好各种变性淀粉浆料提供一些依据。

In accordance with some problems and some wrong guidings on using modified starch size,the writer makes an analysis proceed from tbe basic structure of starch and the basic principle of modification,gives the conformance and the using points for attention of common modified starch,especially in the content of NaCl in CMS,conformance of phosphate starch and the size product comparision between dry processing and wet processing,the writer hopes the analysis can provide basis for using modified starch size in mills.
