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
TanzaniaGlass cleaning and defoaming agent is refined with silicone polyether as the main raw material and various active additives. It is a powder. Defoamer, fast defoaming, long foam suppression, low use cost, high electrolyte resistance, strong acid and alkali resistance, high shear resistance, can eliminate the foam of aqueous system; This product solves the defect that common defoamer lotion is easy to break in high electrolyte, strong acid, strong base and high shear systems. The company's scientific research institute specially develops defoaming powder for the special environment of washing powder. It is mainly a spherical and granular defoaming agent processed through specific equipment using organic silicon and inorganic carriers with specific structures. This defoamer has strong 消泡剂细分词 and inhibiting properties, and will not affect the washing effect due to the production of foam in the washing stage.
