潤滑剂是片剂的重要輔料之一。在常用的潤滑剂当中,硬脂酸鎂阶昂而且不易买到;硬酯酸制粉手續較复杂;滑石粉效能不大、用量多等缺点,所以寻找既經济又方便的潤滑剂,是我們目前要解决的問题。經过一段时間試用硬脂酸与滑石粉的混合物做潤滑剂,我們認为此混合物是一效力較为滿意的潤滑剂。茲介紹于下。一、制法取硬脂酸放在蒸發皿中(或搪瓷盆),于水浴上加热,使其熔融(如有杂物另行过濾),在保溫下逐渐加入滑石粉,混合均匀后,放冷,粉碎,过100目篩即得。制取的成品顏色、与所用原料、器具有关系,滑石粉最好是白色或微黄色。硬脂酸越潔白越好。器具以瓷質、搪瓷及不锈鋼較好。禁用銅器、鉄器,以免与硬脂酸發生作用,而使顏色变深。混合物的比例,我們曾经从1:4到1:10做了7种,其效能随硬脂酸增加而增加,粉碎、过节手绩則随硬脂酸增加而較难。普通以1:6与1:7兩种較为适用。
Lubricant is one of the important accessories for tablets. Among the commonly used lubricants, magnesium stearate is expensive and not easy to buy; the milling process of the stearic acid is complicated; the disadvantages of the talcum powder are not as good as those of the talcum powder; therefore, it is our economical and convenient lubricant that we The current problem to be solved. After a period of time to try a mixture of stearic acid and talcum as a lubricant, we believe that this mixture is a more satisfactory lubricant. It is introduced below. First, the system of law Take stearic acid on the evaporating dish (or enamel basin), heated in a water bath to melt (if there are debris separately filtered), gradually added under the heat of talc, mixed, let cool , Crushed, over 100 mesh sieve that too. Preparation of the finished product color, and the raw materials used, the relationship between equipment, the best talc is white or yellowish. Stearic acid, the more white the better. Appliances to porcelain, enamel and stainless steel better. Disable bronze, 鉄 device, so as to avoid the role of stearic acid, leaving the color darker. The proportion of the mixture, we have done from 1: 4 to 1:10 7 species, its effectiveness increases with the increase of stearic acid, crushing, festival performance with stearic acid increases more difficult. Ordinary 1: 6 and 1: 7 two more applicable.
