Brazil What are the advantages of paint defoamer for water-based cleaning agents(2)
There is no unified understanding of the mechanism of defoaming agents. According to the mechanism of defoaming agents proposed by predecessors, there are generally the following types: [4]
General defoaming mechanism
Typical defoaming mechanisms with a broad overview are the Robinson defoaming mechanism and the Ross hypothesis. Among them, Robinson mechanism is the basis of Ross hypothesis, which mainly emphasizes the liquid drainage of defoamer destroying foam and Marangoni effect to realize defoaming; The Ross hypothesis is based on the fact that the defoamer particles are insoluble droplets, while some defoamers actually produce defoaming effects in a dissolved state, so the defoaming mechanism of the Ross hypothesis is not comprehensive

Water based cleaning agent Defoamer is a polyether based composite defoamer. Due to its water soluble energy consumption, it is easily dispersed in the cleaning agent system, making it convenient and fast to use. No oil phase or little oil phase, excellent defoaming and foam suppression ability and high temperature resistance make it suitable for the production of water-based cleaning agents, effectively eliminating and preventing the regeneration of foam. During production, it can be added after the foam is produced or as a foam inhibitor. According to different use systems, the amount of water based detergent defoamer can be 0.1%~0.8%, but the optimal amount should be determined according to the actual situation. If it is necessary to dilute the defoamer, it is best to conduct a small amount of testing before actual use to avoid abnormalities.

Brazil Will paint defoamer agents for water-based cleaning agents have a negative impact:
water-based
Many people often have concerns when choosing to add water-based defoamers in the production of cleaning agents. Do water-based defoamers affect the viscosity, transparency, and performance of cleaning agents. In fact, the detergent that plays a decontamination role is a surfactant. When the surfactant is dissolved in water, it removes dirt by emulsifying, dispersing, and solubilizing oil. Therefore, the decontamination ability of the detergent is not necessarily related to its viscosity and transparency, so the water-based defoamer does not affect its viscosity and transparency. The decontamination ability of cleaning agents is mainly related to the formula, that is, surfactants, such as anionic surfactants, have more foam than non-ionic surfactants. On the contrary, the defoamer of water-based cleaning agent can also reduce the production of foam and make foam disappear where it should not be, thus greatly improving the effect of cleaning agent.
