Water-based defoamer is used for all water-based system industry inside the defoaming, such as shield mud, water treatment, coal washing, sand washing, desulfurization, paper, cleaning, coating. Water-based defoamers on the market today are polyether, mineral oil defoamer, polyether ester, modified silicone polyether, silicone defoamer, high carbon alcohol, fatty alcohols different occasions and processes choose to use different defoamers. Today we will learn about the water-based defoamer defoaming history and targeted solutions to foam solutions.
【A】Water-based defoamer defoaming process includes what?
Foaming and defoaming process actually includes three aspects.
1, the generation of bubbles in the liquid interior; bubbles in the liquid phase rise and migrate to the surface of the liquid;
2, the rupture of the bubbles in the surface of the liquid phase.
3, by the bubble formation and stabilization process can be seen, to stop the air mixed with the liquid, accelerating the mixing of the bubbles merge and become larger and rise to the liquid surface, prompting the rapid rupture of the bubbles on the liquid surface constitutes the entire content of the defoaming
【B】Only water-based defoamer developed for the environment, the defoaming effect is more ideal
In the industrial encounter foam problems, should be for each system trial selection of defoamer, to find the effect is more suitable for the species, which includes the production process of defoaming effect, defoaming effect and storage stability effect when the material is discharged. In particular, the long-term storage stability of water-based defoamer effect is particularly important.
Because of the complexity and variability of the formulation of water-based systems, there will not be an all-purpose defoamer for all water-based systems. With the emulsions used and the different components of the formulation of the type and amount of defoamer selected are different. Therefore, the defoamer chemical engineers of Nanhui defoamer manufacturers can provide environment-specific waterborne defoamers for the industry and formulation as well as the environment of use. Only with the addition of the applicable defoamer can we achieve a more desirable defoaming effect.
Nanhui defoamer manufacturers developed water-based defoamer and water-based system compatibility is good, the amount of tolerance. Strong defoaming ability, does not reduce the gloss of the system. Is widely used in more than 200 processes, including water treatment, oil fields, mineral processing, power plants and the recent hot coal washing, sand washing, shield mud cleaning and many other industries.
