It is not important with what kind of eps prefoam machine it is, the basic principle of foaming is to mix air into the foaming agent. The change of various machine models is that the way of mixing air is different, so the effect is also different. There are two necessary factors for the formation of foam, one is foaming agent solution, and the other is air, both of which are indispensable. Without the blowing agent solution, the liquid film surrounding the air would not form and there would be no bubbles. And without air, foaming agent solution alone cannot form bubbles.
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 numerous 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 air into the liquid must be done by the prefoam machine which adopts a certain method to mix the air into the liquid.
