当今世界,科学技术的发展日新月异,激光、微波、电子、液氮、真空、乳化、磁化等,这些技术的开发和应用,出现了琳琅满目的商品,供人们选用。 值得一提的乳化技术,它把两种互平相溶的液体,如水和油,通过表面活性剂,混合在一起,即把其中的一种液体变成细小颗粒,再分散到另一种液体中,这种过程叫乳化,形成相对稳定的混合溶液叫乳化液。 如图1所示为油和水放在一个容器中,油和水分离,互不相溶,油比水轻,油漂浮在水上面。若在油和水中加入表面活性剂,即乳化剂(如斯苯80),并进行适当的机械搅拌,也可用超声波或喷
In today’s world, the rapid development of science and technology, laser, microwave, electronics, liquid nitrogen, vacuum, emulsification, magnetization, the development and application of these technologies, there has been an array of products for people to choose from. It is worth mentioning that the emulsification technology, which takes two mutually compatible liquids, such as water and oil, through the surfactant, mixed together, that is, one of the liquid into fine particles, and then dispersed into another liquid In this process is called emulsification, the formation of a relatively stable mixed solution called emulsion. Shown in Figure 1 for the oil and water in a container, the oil and water separation, mutually incompatible, oil lighter than water, floating in the water above the surface of the oil. If the surfactant is added to the oil and water, that is, the emulsifier (such as benzene 80), and the appropriate mechanical stirring, ultrasonic or spray
