NECESSARY CONDITIONS FOR HIGH-PRESSURE FOAMING MACHINE TO FORM FOAM

A high-pressure foaming machine is a device that can make a foam with an aqueous solution of a certain concentration of a foaming agent. The foaming agent itself cannot automatically become a foam. It must pass the mechanical action of the high-pressure foaming machine to become a foam. The high-pressure foaming machine and the foaming agent are a technical system that cooperates with each other and cannot function alone.

The high-pressure foaming machine itself cannot produce foam out of thin air. It introduces air into the foaming agent aqueous solution to evenly disperse it to achieve the largest possible contact surface between liquid and gas, so that the surface active substances in the foaming agent are in the liquid film. An electric double layer is formed on the surface and surrounds the air, forming a bubble.

No matter what kind of foaming machine, the basic principle of foaming is to introduce air into the foaming 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 foaming agent solution, and the other is air, both of which are indispensable. Without the blowing agent solution, the liquid film surrounding the gas would not form, and there would be no bubbles. And without gas, foaming agent solution alone will not 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 gas into the liquid must be completed by a high-pressure foaming machine, that is, the high-pressure foaming machine adopts a certain method to introduce gas into the liquid.
