Understand how to choose the fermentation agent in every aspect

1. Insoluble or insoluble in foaming solution.
In order to burst foam, the bubble film is concentrated and concentrated in the foam film.. In the case of the bubble agent, the instant concentration and concentration should be kept in the condition of the bubbles.. Therefore, the foaming agent is in the foaming liquid is over saturated state, only insoluble or insoluble and easy to reach the saturated state. Insoluble or insoluble, it is easy to gather in the gas-liquid interface, it is easy to concentrate on the film, in order to play a role in the lower concentration. For the water system, the molecule of the active ingredient, the active ingredient, must be weak hydrophilic, the HLB value is in the 1.53 range, the function is the best.. Such as silicone or polyether foam agent.
2, the surface tension is lower than foaming liquid
Only the intermolecular force of the anti - agent is small, the surface tension is lower than the foaming liquid, and the particles can be immersed and expanded in the film. It is worth noting that the surface tension of the foaming solution is not the surface tension of the solution, but the surface tension of the solution..
3, and foaming liquid have a certain degree of affinity
The defoaming is actually the process of collapse of the bubble velocity and velocity of bubble generation competition, so the fire foam agent must be able to in the bubble liquid quickly dispersion so quickly in the foaming liquid in a wide range to play a role. In order to make the bubble spread quickly, the active ingredient of the anti foaming agent must have a certain degree of affinity with the foaming liquid. The active ingredient of the anti - agent and the foaming liquid are over - pro - dissolved, and too sparse and difficult to disperse.. Only the effect will be good for them.
4. No chemical reaction with foaming liquid
The reaction between the foaming agent and the foaming liquid, on the one hand, can lose the effect of the foam agent, on the other hand, it may cause harmful substances, which may affect the growth of microorganism..
5, volatile, long time of action.
The above is how to choose the fermentation of the consumer agent, we want to help.
