What are the methods to test the performance of defoaming agents?
When people use defoaming agents, they must be tested, otherwise they may not achieve the best results. So what are the methods for testing the performance of defoaming agents?
1. The shake flask method can be used for testing
The simplest way to use it is to shake the flask test. Add some foaming liquid into the measuring cylinder. When shaking the flask up and down, pay attention to the same number of times. After that, you can let it stand and observe to see the height of the foam. , and the final defoaming time, etc.
2. Spray experiment can also be used
This kind of experiment is also a very common test method. The so-called spray test is to create some bubbles in the form of spray bubble solution, then add a defoaming agent to them, and measure the final defoaming effect of the defoaming agent based on the final defoaming time.
