Mineral oil defoamers are usually composed of a carrier and an active agent, and the carrier functions as a carrier and a diluent. The action of the active agent is to prevent and defoam the foam. Mineral oil defoamer has a low surface tension and can play a preventive role. Mineral oil is insoluble with water on the liquid film of the foam, destroying the integrity of the liquid film, destroying the recovery and fluidity of the liquid film, thereby breaking the foam and achieving the effect of defoaming.
What are the advantages and disadvantages of mineral oil defoamer and its application?
Mineral oil defoamer works in both acidic and alkaline conditions. And it has good heat resistance, versatility, and non-combustible, non-explosive characteristics. The use of mineral oil defoamers also affects the basic properties of the foaming system. Its price is also relatively cheap. Can be used in mining, oil refining, smelting, oil fields, drilling, mineral processing and other fields. However, mineral oil defoamer has poor compatibility, is not very good for defoaming of dense foam, and is not suitable for high shear environment. Not suitable for use on products that have strict color requirements.
