Defoamers : Typology, Production, and Applicability
You rather look for a layer of foam in your cup of coffee, but they pose a serious menace to industrial solutions and processes, and to the environment at large. Hence on the formation, a chemical solution is used to inflict a knock-down effect on it, which is referred to as defoamer. Defoamers are commonly used in industrial processes and products such as wood pulp, paper, paint, industrial wastewater treatment, food-processing, oil drilling, machine tool industry, oil-cutting tools, hydraulics etc. . Depending upon the ingredients that go into the production of defoamer, they can be classified as follows:- Oil-based defoamer generally contain oils that are insoluble in the foaming medium, such as mineral and vegetable oils. Wax and hydrophobic silica may be added to boost performance by improving emulsification and facilitating widespreadness in the foaming medium. These are heavy duty defoamer used in tackling down the surface foam. Powder defoamer are in ...
