油与水是两种互不相溶的液体,但是在乳化剂与机械力的作用下,在适宜的温度与体积比例中,可以使油均匀稳定的分散于水溶液之中,成为乳状液这种现象即称为乳化。根据乳化剂品种的不同,油与水可以乳化成为水包油状的乳状液,这种乳液具有水的特性,可以分散于水中,例如乳化沥青就是这种乳状液;另一种是油与水乳化成为油包水状的乳状液,这种乳液具有油的特性,
Oil and water are two mutually incompatible liquids, but under the action of emulsifier and mechanical force, the oil can be uniformly and stably dispersed in an aqueous solution in an appropriate ratio of temperature and volume to become an emulsion Phenomenon is called emulsification. Depending on the type of emulsifier, the oil and water can be emulsified into an oil-in-water emulsion that has the properties of water and can be dispersed in water, such as emulsified asphalt, and the other is emulsified with oil and water Become a water-in-oil emulsion, this emulsion has the characteristics of oil,
