制备乳剂用的西黄蓍胶粉与阿拉伯胶粉等乳化剂,皆系由国外进口,售价高。而该二胶粉除供配制乳剂外其他如作混悬剂、粘合剂等尤为常用,每年除给国家耗费外汇外,更主要的是由于缺货,往往影响鱼肝油乳及某些混悬剂的生产。根据顾学裘等研究报告,白芨胶浆粘滞度及混悬力较同浓度的西黄蓍胶浆及阿拉伯胶浆为大,且白芨胶粉具有一定乳化能力,此点对鱼肝油乳剂制备又增加了一有利条件,因西黄蓍胶粉仅增加乳剂粘稠度,而乳化作用则
Preparation of emulsion with tragacanth powder and Arabia powder and other emulsifiers, are all imported from abroad, high prices. In addition to the second powder for the preparation of emulsion other than as suspensions, adhesives, etc. are particularly common, each year in addition to consuming foreign exchange, the more important is due to out of stock, often affect the cod liver oil emulsion and certain suspensions Production. According to Gu Xueqiu and other research reports, the viscosity and suspension of Baizhi mortar than the same concentration of tragacanth and Arabia mortar is large, and Baijiao powder has some emulsifying capacity, this point on the preparation of cod-liver oil emulsion increased A favorable condition, because of the addition of tragacanth powder emulsion viscosity, while the emulsification is
