Analysis of defoaming process of silicone defoamer
Nowadays, when treating sewage, silicone defoamer is generally used, and the effect is good. So what is the defoaming process of silicone defoamer?
1. General process
When a silicone defoaming agent is added to the foam, it will disperse quickly, and the active agent molecules will be oriented in the bubbles. When the defoaming agent is at a certain concentration and there are many active agent molecules, it will A thin film appears on the bubble wall, which reduces its tension and increases the contact surface. The bubbles are not easy to merge and may burst.
2. Defoaming process
The bubble film exposed to the air is a bimolecular film. To remove the foam, the film between the air and liquid must be destroyed, and the defoaming agent in it can quickly spread on the solution and enter the foam directional film, destroying the balance in the film. properties, this achieves the defoaming effect.
