United States What are the advantages of No Foam for water-based cleaning agents(2)








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.




United States Will No Foam agents for water-based cleaning agents have a negative impact:

The larger the molecular weight, the stronger the control ability of its surface state, and the better its skid resistance and adhesion resistance, such as the 1070 and 1071 series products of the friction chemical industry.
There are two methods for bonding modified polyester or polyether to siloxanes: one is a silicon oxygen bond; The other is silicon carbon chains, which generally have less thermal stability and water resistance than the latter.
The compatibility of polyether and polyester modified siloxanes with resins has been greatly improved, reducing surface tension, controlling surface flow, increasing slip resistance, anti shrinkage, and anti adhesion. Some products also have interlayer adhesion issues. In particular, polyether modified polysiloxanes have poor thermal stability and are prone to foam stabilization. It is important to pay attention to the negative effects of these products when applying them.


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.
