消泡剂（消泡剂）化学品是许多工业过程的重要组成部分。综述了消泡剂的类型及其操作方式。重点介绍了作为活性破泡剂的疏水粒子的性质和分布。还讨论了表面活性剂在铺展、消泡剂乳化和疏水性颗粒取向中的作用。最后，描述了一个简单的模型，该模型模拟了作为消泡剂浓度、空气滞留量、反应器体积和空气流速的函数的泡沫生长。
Antifoam (defoamer) chemicals are a crucial part of many industrial processes. Reviewed are the types of defoamers and their mode of operation. Emphasized are the properties and location of the hydrophobic particles which are the active foam breaking agents. The roles of surfactants in spreading, defoamer emulsification and hydrophobic particle orientation are also discussed. Finally, a simple model is described which simulates foam growth as functions of defoamer concentration, air hold-up, reactor volume and air flow rate.
