Foam problems exist in many industrial production processes, leading to inconvenient operation, waste equipment capacity, affect the quality of finished products, etc. Especially under the condition that the scale of industrial production is getting larger and larger and the production efficiency is getting higher and higher. The need to eliminate bubbles quickly and efficiently in the shortest possible time requires new and more effective methods to eliminate bubbles. Silicone defoamer can provide an efficient defoamer solution for foam problems in industrial production due to its excellent performance, economic use, easy processing and diverse functions. It has been widely used in sewage treatment, paper making, printing and dyeing, food and chemical production.


one


The advantage of silicone defoamer






Significantly lower dose ratio effective compared to other organic defoamants, resulting in significantly lower cost of use (50 PPM effective)




Durability is often much longer (longer lasting) than other organic defoamer




There is often less reactivity in foaming media, thus reducing compatibility issues




Stable over a wide range of temperatures and PH

Classification of silicone defoamer




According to the different application environment needs of defoamer, silicone defoamer products mainly have the following types:




Fluid type: Inert, low toxic silicone oil with a wide viscosity range and defoamer in non-aqueous systems




Dispersion: Dispersion of aliphatic solvents, mainly used in oil and gas production processes




Compound: 100% active ingredient - oily, containing hydrophobic silica powder to improve defoaming efficiency, mainly used in non-aqueous systems




Emulsion: A complex of defoamer emulsified in water, suitable for controlling foam in aqueous system applications




Concentrated liquid: highly concentrated polyether modified self-emulsifying product




Powder: A solid powdered compound defoamer that can be added to dry products to prevent foaming when liquid is added, such as in laundry detergent
