Stability factors of foam
The direct cause of foam is the presence of surfactant, which reduces the surface tension of the solution. Under the combined effect of this reason and the attenuation mechanism of foam, different foam systems show different stability properties, which are mainly related to the following factors: the surface tension of foaming solution, the surface viscosity of foam, the viscosity of solution, the self-healing effect of surface tension (i.e. Gibbs surface elasticity and Marangoni effect) "The surface double layer repulsion and entropy repulsion forces of liquid membranes, the hydrophobic end structure of surfactants, and the steric hindrance effect are not independent factors, and changes in one factor can cause other factors to also change.". The most important factors affecting the stability of foam are the elasticity of the liquid film and the liquid discharge rate. From this perspective, it can be seen that the main factors affecting the stability of foam are different in different foam systems, and sometimes several factors exist at the same time and work together.
In addition to the above factors, some other factors will also affect the stability of foam, such as the size of foam, the coordination of solute and solvent, temperature, pH value, the evaporation rate of solvent, the impact degree of foam and the adsorption rate of surfactant

Togo It is also worth noting how to select  Free of silicone defoamers for beer bottle cleaning. Firstly, they must be insoluble in the foaming liquid and have a lower surface tension than the foaming liquid, so that defoamers can play a role. Then, it should have a certain affinity with the foaming liquid. The defoaming process is actually a competition with the foam production. Only by rapidly dispersing the effect in the starting liquid can we achieve the goal of defoaming. The active component of the defoamer is too hydrophilic to the foaming liquid and will dissolve; Too sparse and difficult to disperse. Only when intimacy is appropriate can effectiveness be good. Finally, it is not allowed to react chemically with the foaming liquid, otherwise harmful substances may breed and affect product performance
