我读了韩熹莱先生的“谈谈矿物油乳剂”一文后,想提出一点配制乳剂的注意事项,以供各地配制时参考。 1.水 一般常用的是“热制肥皂石油乳剂”。此剂在配制时要用热水(越热越好),这可调制成良好的乳剂。稀释时也要用热水或温水。冷水则破坏乳剂,有粘稠的膏状物产生。如果乳化剂是肥皂,则忌用硬水。 2.油 冷油(即不加温的油)配制的乳剂不好,有油漂浮在水面(指轻于水的油),热油则无此弊病。但在加热时要注意避免着火。一般,煤油加热到
After reading the article entitled “Talks on Mineral Oil Emulsions” by Mr. Han Xi Lai, I would like to make a point about the precautions for formulating emulsions for reference when formulating them all over the world. 1. Water commonly used is “hot soap oil emulsion.” This agent is used in the preparation of hot water (hotter the better), which can be modulated into a good emulsion. Also use hot water or warm water when diluting. Cold water destroys the emulsion, creating a sticky paste. If the emulsifier is soap, avoid using hard water. 2. Oil-cold oil (ie, not warm oil) formulated emulsion is not good, floating in the water flooding (referring to lighter than water), hot oil is no such malady. But in the heating should pay attention to avoid the fire. In general, kerosene is heated to
