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.

South Africa Will paint defoamer agents for water-based cleaning agents have a negative impact:

Leveling agents are generally divided into two categories. One type of leveling agent works by adjusting the viscosity and leveling time of the paint film. Most of these leveling agents are organic solvents or mixtures with high boiling points, such as isophorone, diacetone alcohol, Solvesso 150, etc; The other is to adjust the surface properties of the paint film to play a role, and generally speaking, leveling agents refer to this type of leveling agent. This type of leveling agent migrates to the surface of the paint film through limited compatibility, affecting surface properties such as interfacial tension of the paint film, and achieving good leveling of the paint film. Depending on the chemical structure, there are three main types of leveling agents: acrylic acids, organosilicon, and fluorocarbon compounds

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.
