Cook Islands Differences in water-based mineral oil Free of silicone defoamers(2)

Attenuation mechanism of foam
Under the condition of gravity and pressure difference, the liquid membrane of foam will flow and discharge liquid unevenly, and the gas in the bubble will continue to diffuse and permeate due to the different pressure difference on both sides of the bubble membrane, so the instability of foam itself is mainly reflected from the dynamics. [4]
The attenuation mechanism mainly includes the diffusion of gas through the liquid film and the discharge of liquid from the liquid film. These two properties are inherent attributes of foam itself, and have nothing to do with the existence of surfactant. However, these two attenuation mechanisms only play an obvious role in the initial stage of foam system formation. With the attenuation of foam system, these two effects gradually weaken, making the foam attenuation rate gradually slow. [

The water-based mineral oil Free of silicone defoamershas a fast defoaming speed and a foam inhibiting effect of up to several hours, which is also well matched with the foam system. It can be carried out in harsh environments such as high temperatures and strong alkalis, with good results. After use, there will be no phenomena such as oil bleaching and demulsification

替换城市  Waterborne mineral oil Free of silicone defoamers are suitable for use in water-based systems with weak emulsifying properties, such as latex paints, coatings, adhesives, inks, and other systems with low emulsifying properties. They are easy to emulsify and form uniform distribution in water-based systems, thereby reducing the likelihood of surface defects such as shrinkage and loss of gloss, and also reducing microbubbles. However, it should be noted that mineral oils and waxes, which contain a small amount of organosilicon, and adopt special preparation processes, have excellent product storage stability, and are not prone to separation or sedimentation even after long-term storage.
