    Mineral oil is mainly a mixture of saturated naphthenes and paraffins, which are used in various industries such as washing powder, synthetic detergent, synthetic petroleum protein, and pesticide emulsifier. So what happens when it is combined with a defoamer? As we all know, there are three major types of defoamers, silicone, polyether, and mineral oil. What kind of unique charm does mineral oil defoamer have?

    It should be known that mineral oil defoamers are widely used in various industries, such as: wastewater treatment after ink and paint production, a large amount of foam due to excessive chemical additives in wastewater and surfactants in circulating water. In the production of water-based coatings, it is necessary to add chemical additives followed by mechanical and physical effects, so that air can enter into it to generate a large amount of foam, etc. Mineral oil defoamers can be used. Whether it is physical or chemical factors, mineral oil defoamers can deal with it freely.

    The main components of mineral oil defoamers contain mineral oil, inorganic hydrophobic particles, and emulsifiers, which can be used in all areas that are not suitable for silicone defoamers. The inorganic hydrophobic particles will be evenly distributed in the mineral oil, and then through the action of the emulsifier to achieve the characteristics of self-emulsification and dispersion of the defoamer, and finally form an emulsion that can be dispersed in water and become a moderately stable emulsion——mineral oil defoamer foaming agent. Due to its good diffusibility and permeability, the defoaming factor can more easily reach the liquid film surface and the water-insoluble state, destroying the integrity of the liquid film, so that the foam bursts to achieve defoaming; and the mineral oil defoamer itself It has low surface tension and is dispersed on the surface of the liquid to make it difficult to foam again to achieve the effect of foam suppression.
    Advantages and disadvantages of mineral oil defoamers:
    Of course, a product is like a double-edged sword, with both advantages and disadvantages. Mineral oil defoamer can achieve rapid defoaming and long-term antifoaming, and at the same time, it has a high degree of matching with the foaming system; and it has good heat resistance and chemical stability, and is resistant to acid, alkali, salt, electrolyte and hard water. Can be used, can be used in different production environments in all walks of life and is not prone to demulsification and floating oil. Using it can make production more assured and more reliable.
    However, the defoaming effect of mineral oil defoamer in the face of too dense foam layer is relatively general, and its compatibility is not as good as polyether and silicone.
