大陆法(干胶法)制乳剂的设计原理,文献中很少记载。1964年在上海举行的全国药剂研究工作经验交流会上,提出这个问题,未得到解决。现在谈一谈个人对这个问题的想法。我认为大陆法是为小量调制乳剂设计的(因所用乳化剂为阿拉伯胶,成本高、用量大,不适于工业生产应用)。设计结果很成功,方法简单易行,比当时流行的英国法(胶浆法)省工省时,制成品更均匀乳白;解决了配制小量乳剂主要困难:工具(乳钵)效率低,不易将油类分裂到适于乳化程度。为克服这个困难,设计者采取从小量做起,先制成初乳。这样安排很科学,因在胶体全量比例大时,乳钵的效率相应的也大,比较容易将油分裂成小滴,使之乳化。此外为乳化作用创造有利条作,先在油中加25～100%胶粉研均,
Continental Law (dry glue law) system design principles of emulsion, rarely documented in the literature. At the exchange meeting on national pharmacy research experience held in Shanghai in 1964, this issue was raised unsolved. Let me talk about my personal thoughts on this issue. I think the mainland law is designed for a small amount of emulsion modulation (because the emulsifier used is gum arabic, high cost, large amount, not suitable for industrial applications). The design result was very successful and the method was simple and easy. Compared with the popular British method (mortar method), the finished product was more uniform and milky white than the popular British method at that time. The main difficulties in formulating the small amount of emulsion were solved: the efficiency of the tool (mortar) Not easy to split oil suitable for emulsification. To overcome this difficulty, designers take a small amount to start with colostrum. This arrangement is very scientific, because the large proportion of colloidal full, the corresponding efficiency of the mortar is relatively large, it is easier to split the oil into droplets, so that the emulsion. In addition to create favorable conditions for the emulsification, first in the oil plus 25 ~ 100% powder research,
