The Main Components Of Chemical Defoamers Are These!

Foaming phenomenon often occurs in the chemical process, and foam may affect the operation process of the production unit, resulting in substandard finished products, so it is necessary to conduct regular treatment of foam. Choosing a suitable chemical defoamer can not only ensure the normal operation while defoaming, but also improve the purity of chemical products. Among them, chemical defoamer has a close relationship with its composition to realize its excellent defoamer, defoamer and other functions.

Chemical defoamer can be divided into three categories according to its shape: mucous, liquid and solid defoamer. Chemical defoamer is mainly composed of main defoamer, auxiliary defoamer, carrier, emulsifier or spreading agent, stabilizer and so on. In order to complete the research and development of a chemical antifoaming agent, two or more components may be needed to achieve synergistic realization, or one component may have multiple functions at the same time.

Primary defoamer

It is an insoluble granular material, which is usually insoluble in various foaming systems and carriers, and can also be understood as a defoaming surfactant. This component also gives chemical defoaming agent chemical stability and is not easy to lose the function of defoaming activity under special conditions.

Auxiliary defoamer

Its existence mainly plays the role of assisting the main defoamer, it can improve the spread, crystallinity and solubility of the main defoamer in the foam medium and carrier, is an indispensable ingredient in the formula of defoamer. At the same time, its existence is to strengthen the dispersibility of chemical defoaming agent, so that it has the function of fast defoaming speed and long defoaming time.

carrier

Generally, it is water, liquid oil or organic solvent existing substances, it needs to adapt to the environmental conditions, pH value and temperature to play its role, the introduction of the main defoamer and auxiliary defoamer provides the medium, is also the main body of chemical defoamer formula, can enhance its defoamer effect.

Emulsifier or spreading agent

Chemical defoamer itself does not have the function of defoamer, so it can only be applied to the system after emulsification or spreading, so it will also add emulsifier or spreading agent to its ingredients, so that the use of defoamer is less, and to a certain extent, it also saves our cost
