Defoaming mechanism of hydrophobic solid particles
Hydrophobic solid particles in the foam system will first attract the hydrophobic end of the surfactant, making the hydrophobic solid particles become hydrophilic, thus reducing the concentration of surfactant in the foam film and promoting the foam to burst. This defoaming mechanism cannot explain the action mechanism of other defoaming agents, which is too one-sided. [4] Other reasons for the bursting of foam are the impact caused by the expansion of defoamer, the solubilization of surfactant and the collapse of electrolyte, and the bursting of electric double layer on the liquid film surface. [4] It can be seen from the above defoaming mechanisms that each defoamer has different emphasis on different foam systems, but defoaming is achieved by destroying the stability factors of foam

Venezuela When general sand washing plants are carrying out sewage treatment, they should start to add chemicals to assist after the completion of sediment separation, fine sand extraction and other work. However, the complex composition of such chemicals combined with the influence of external factors will produce foam in sand washing wastewater treatment, which will bring only disadvantages but no benefits. For the treatment of sediment and sand washing wastewater, the sand washing wastewater treatment defoamer can not be more appropriate to eliminate the foam problem. It is targeted at the foaming mechanism and link system of the sand washing system. The finished products are mainly refined from organosilicon, polyether and other core components. Directly adding at the water inlet will not affect the separation and cleaning of sediment and other sediment,

Venezuela In addition, the sand washing wastewater treatment paint defoamerr can also be used for the wastewater after sediment cleaning. This system is different from wastewater treatment. In order to make the sediment cleaning effect better, the staff will add stabilizer and cleaning agent to assist in cleaning. The foaming factor in these additives is also one of the culprits for the emergence of a large number of foam. The polyethers in the sand washing wastewater treatment paint defoamer are specially designed for the sediment cleaning system, mainly to solve the foam in the process of water circulation washing sediment, and also applicable to the water treatment stage in the mud water separation.
