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.

Bei Ning The Free of silicone defoamers powder used for beer bottle cleaning and defoaming is also one of these types. This type of cleaning and defoaming agent is developed using silicone polyether as the main raw material, combined with a variety of additives. With low dosage, convenient operation, and easy solubility in water, there is no need to mention the  Free of silicone defoamers and foam inhibiting properties. The main thing is to value the good dispersion of such  Free of silicone defoamers agents, which will not affect the transparency and appearance performance of the product. Good compatibility with various surfactants used in beer bottle cleaning, while not reducing the cleaning effect, solves the problem of spot residue, and has no side effects on subsequent processing. The amount of defoamer added for beer bottle cleaning is one thousandth to three thousandths, but the final amount should be determined according to the cleaning water volume of different manufacturers and the content of detergent. Powdery defoamer can be added to the foam surface after the powder and water are boiled.
