Alkyl modified organosiloxane
As mentioned earlier, polyether modified polysiloxanes have some shortcomings; Alkyl modified polysiloxanes have precisely these advantages.
This series of polysiloxane products also belong to the comb structure. The molecular weight of this type of product is relatively small, around 10000, and n+m is about 30-50. The main purpose of modifying with alkyl is to improve thermal stability, compatibility, and unstable foaming, and even to have defoaming functions. However, as the modified alkyl chain increases, its ability to reduce surface tension also decreases

Equatorial GuineaWhen choosing Free of silicone defoamers 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 fee
