Action mechanism of polysiloxane defoamer
The representative defoaming mechanisms of polysiloxane mainly include "bridging spreading" mechanism, "bridging dehumidifying" mechanism, and "spreading liquid entrainment" mechanism. The "bridging spreading" mechanism mainly starts from the basic point of "polysiloxane has a relatively low tension and is easy to spread on the liquid film." It emphasizes that defoamer droplets are prone to deformation, but this theory cannot explain the defoaming differences between individual polysiloxanes and mixtures of polysiloxanes and solid ions as defoamers. The "bridging dehumidification" mechanism is mainly based on the hydrophobicity of polysiloxanes themselves, but the defoaming effect of polysiloxanes with high viscosity cannot be well explained. The "spreading liquid entrainment" mechanism cannot be confirmed because some facts indicate that polysiloxanes sometimes do not spread on the surface of the foam film, but can also break the foam.

    MalawiGlass cleaning and defoaming agent is refined with silicone polyether as the main raw material and various active additives. It is a powder. Defoamer, fast defoaming, long foam suppression, low use cost, high electrolyte resistance, strong acid and alkali resistance, high shear resistance, can eliminate the foam of aqueous system; This product solves the defect that common defoamer lotion is easy to break in high electrolyte, strong acid, strong base and high shear systems. The company's scientific research institute specially develops defoaming powder for the special environment of washing powder. It is mainly a spherical and granular defoaming agent processed through specific equipment using organic silicon and inorganic carriers with specific structures. This defoamer has strong 消泡剂细分词 and inhibiting properties, and will not affect the washing effect due to the production of foam in the washing stage.
