What Is Mineral Oil Defoamers
Mineral oil defoamers consist of approximately 85–95 % mineral oil and 1–3 % hydrophobic particles. They also contain emulsifiers, biocides and other performance-enhancing ingredients such as modified polysiloxanes. Aliphatic mineral oils are used as the carrier oil. Emulsifiers are required in defoamers to ensure efficient dispersion of the particles in the mineral oil. They also make it easier to incorporate the defoamer in the coating formulation.

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.
The defoaming mechanism of mineral oil is that mineral oil is insoluble with water on the liquid film of the foam, destroying the integrity of the liquid film, causing the recovery of the liquid film and the fluidity to be destroyed, thereby causing the foam to rupture and thereby defoaming. Even in the emulsion, the mineral oil is only emulsified and water, and is not soluble in water. Therefore, the larger the mineral oil droplets, the better the defoaming, that is, the defoaming of the emulsion (milky white) is generally better than that of the microemulsion. Translucent, transparent). The carbon chain of mineral oil has little effect on defoaming.
Application of Mineral Oil Defoamers
Mineral oil defoamers applied for all types of synthetic latex, in particular applied to rubber and plastics industry polymerization, condensation,degassing step,can eliminate foam produced by different surfactants in this system. And it can also be used in resins, water-based paint, latex paint, water-based ink, emulsion polymerization, polymer gel, lotion benzene Bing black liquor, petrochemical and all NA silicone defoamers industry.
Because increasingly sharpening of environmental issue, people's environmental consciousness also strengthen day by day, the needed auxiliary agents of industry such as weaving, leather, packing, coating, printing ink are Water-borne modification more and more.And the Water-borne modification product must just can reach hydrophilic effect by the introducing of hydrophilic radical or surfactant, the use of exhibiting high surface activating agent must bring inevitable side effect, be the generation of foam, the existence of foam has brought serious harm for production, use and the post-processed etc. of product.Therefore aqueous product has higher froth breaking requirement than oil product, and in order to reach this requirement, increasing defoamer comes out, and the antifoam performance of most of product does not reach requirement.The a kind of of the present invention exploitation is the defoamer of main component with wax, is mainly used in adhesive and water treatment field, has good antifoam performance, and it is perfect market product is for the aqueous promoter series products provides novel defoamer kind.

Factors to Consider When Choosing an Mineral Oil Defoamers
In aqueous environments, the right antifoam or defoamer product can minimize or eliminate issues associated with foam. Some of the questions you should answer before choosing an antifoam or defoamer for a given application include:
Is the antifoam/defoamer compatible with the process?
Antifoams and defoamers are generally inert chemicals consisting of a liquid (e.g., silicone, mineral oils, or hydrophobic surfactants) and a hydrophobic solid (e.g., fatty acids, fatty alcohols, silica, or wax). Ultimately, the antifoam/defoamer you select should have a balance of compatibility and incompatibility. It should be compatible enough that it effectively disperses in the foaming medium. Otherwise, it may cause deposition issues. However, it should be insoluble to the point that it remains in fine droplet form within the solution.
Will the antifoam/defoamer cause deposit issues?
The antifoam/defoamer should be sufficiently compatible within the solution so as to not create deposits. Will the antifoam/defoamer negatively affect the catalyst I am using? The antifoam/defoamer should not negatively impact any catalysts used in the process.
Will the antifoam/defoamer plug up any membranes or filters?
The antifoam/defoamer should not carry the potential for plugging/clogging filters and membranes that can compromise the product or process.
Is the antifoam/defoamer composition effective for my application?
Antifoams and defoamer come in many varieties. The one you choose should suit your individual requirements and restrictions. Will the antifoam/defoamer have any negative effects on downstream conditions? The antifoam/defoamer should not cause any adverse downstream effects. The answers to these questions must be weighed appropriately. In some cases, you must compromise on a solution.
