defoamer

The chemical methods to eliminate foam mainly include chemical reaction method and adding defoamer. The chemical reaction method refers to the chemical reaction between the foaming agent and the foaming agent by adding some reagents to generate water insoluble substances, thus reducing the concentration of surfactant in the liquid film and promoting the rupture of foam. However, this method has some shortcomings, such as the uncertainty of foaming agent composition and the harm of insoluble substances to system equipment. Nowadays, the most widely used defoaming method in various industries is the method of adding defoaming agents. The greatest advantages of this method are high foam breaking efficiency and convenient use, but finding suitable and efficient defoaming agents is the key.

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 Mongolia rate is not high. The advantages are environmental protection and high reuse rate.
