白糊精;
Optimum concentration is 4%-5% sulphuric acid and mixed thickener with emulsion thickener and gum tragacanth and white dextrin. Better stability of printing paste and excellent effect of burn-out printing are available.
选用浓度为4%~6%的硫酸及乳化糊、龙胶、白糊精拼混糊料,印浆稳定性好,烂花效果佳。
The dry preparation conditions of white dextrin. At first, the factors which affected dry preparation of white dextrin were studied by single factor experiment, such as: the quality ratio of Hcl/ starch, moisture content, reaction temperature and reaction time.
主要试验结果如下:1、白糊精干法制备工艺的研究通过单因素试验,研究了浓盐酸加入量与淀粉质量之比、体系含水量、反应时间、反应温度对白糊精的糊精化反应的影响。
