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.

AlbaniaWhen choosing ink defoamer for aquaculture wastewater treatment, let's first see what kind of foam in wastewater belongs to, which is usually divided into chemical foam and biological foam. Chemical foam is also divided into active agent foam and oil and suspended solids foam. Active agent foam: when detergent, colloidal organic matter and other surfactants or other foaming substances are present in the sewage, under the conditions of water flow speed, fall, aeration, blowing off, etc., a large number of small and light white brown unstable foam will appear on the water surface. This kind of wastewater is a high molecular synthetic substance with poor biodegradability, which is a problem in sewage treatment. Biological foam: It is generally earthy brown or grayish brown, and there are many reasons for this kind of foam, so it is difficult to deal with. With the defoamer for aquaculture wastewater treatment, it is not necessary to consider whether it is suitable or not. This defoamer has strong versatility and can adsorb surfactants and change the hydrophilicity of surface activity. After dilution and regulation, it can enter biochemical treatment, which can solve the problem of chemical foam or biological foam. How much is the quotation

Albania The antifoaming agent for aquaculture wastewater treatment is ink defoamerfor the aquaculture wastewater industry system. It can quickly disperse in water, is easily soluble in water, is not easy to break emulsion and float oil, and is fast in ink defoamer and long in inhibiting foam. It does not change the oxygen content of water quality or the microorganisms in the water, and has good acid and alkaline resistance, wide application range, and good chemical stability.
