Afghanistan There are two ways to eliminate foam:

defoamer

Dispersant is a kind of interfacial active agent that has both opposite properties of lipophilicity and hydrophilicity within the molecule. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, while also preventing particle sedimentation and condensation, forming amphiphilic reagents required for stable suspensions

From the physical point of view, the methods to eliminate foam mainly include placing baffle or filter screen, mechanical agitation, static electricity, freezing, heating, steam, radiation, high-speed centrifugation, pressure reduction, high-frequency vibration, instantaneous discharge and ultrasound (acoustic liquid control). These methods promote the gas transmission rate at both ends of the liquid film and the liquid discharge of the bubble film to varying degrees, making the stability factor of foam less than the attenuation factor, As a result, the number of foam gradually decreased. However, the common disadvantage of these methods is that their use is strongly restricted by environmental factors, and the Afghanistan rate is not high. The advantages are environmental protection and high reuse rate.
