No matter what kind of Auto Eps Batch Pre-expander Machine, the basic principle of foaming is to introduce air into the blowing agent solution. The change of various models is that the way of introducing gas is different, so the effect is also different.

There are two necessary factors for the formation of foam, one is the blowing agent solution, and the other is air, both of which are indispensable. Without the blowing agent solution, the liquid film surrounding the gas does not form and there are no bubbles. In the absence of gas, bubbles cannot be formed with a blowing agent solution alone.

In the bubble formation system, the blowing agent solution is the dispersion medium, the gas is the dispersed phase, and the gas is dispersed in the liquid to form bubbles, and then the foam is composed of countless bubbles. In addition to the important factor of blowing agent performance, the introduction of gas into the blowing agent solution is another important factor. The introduction of gas into liquid must be done by Auto Eps Batch Pre-expander Machine, that is, Auto Eps Batch Pre-expander Machine uses a certain method to introduce gas into liquid.
