Mineral oil defoamer is one of the more common types other than silicone and polyether defoamers. Mineral oil defoamer is used in industrial manufacturing. The surface tension of the mineral oil defoamer is low. It has a preventive effect. Mineral oil components in the liquid film of the foam are incompatible with water will destroy the integrity of the liquid film leading to the liquidity being hindered and damaged eventually to prevent the rupture of the foam from achieving the effect of defoaming and foam inhibition. So the
mineral oil defoamer ingredients those?
The composition of mineral oil defoamer is composed of mineral oil or other insoluble in foam medium oil as a carrier of about 50%-70%. Its specific gravity size is the key. Too large will affect the solubility and emulsification. Too small will affect its stability and effect.
Inorganic hydrophobic particles account for about 10%. It will be uniformly dispersed in the mineral oil is a very critical factor. Because its hydrophobic strength determines the effect of defoaming performance can help defoaming factors easier to reach the surface of the liquid film so that the defoamer quickly and fluid film integration increases the speed of defoaming.
Emulsifier is also known as defoamer additives. Its purpose is to increase the emulsification performance to increase the normal play of the defoamer. An emulsifier ratio of 10% is usually used and mineral oil compatibility does not affect the appearance of performance will be compounded into the mineral oil defoamer can play a role in the water phase system and help with defoaming factors defoaming.
