Regardless of the foaming machine, the basic principle of foaming is to introduce air into the foaming agent solution.
Various models vary in the way the gas is introduced, and thus the effects are different. The formation of foam has two necessary factors, one is the blowing agent solution, two is the air, both indispensable. Without a foaming agent solution, the liquid film that surrounds the gas will not form and there will be no air bubbles.
And no gas, single blowing agent solution, bubble can not form. In the bubble formation system, the blowing agent solution is a dispersion medium, the gas is dispersed, the gas dispersed in the liquid, in order to form bubbles, and then by the countless bubbles formed foam. In addition to the important factor of foaming agent performance, the introduction of gas into the foaming agent solution is another important factor.
And the gas into the liquid, must rely on the foaming machine to complete, that is, the foaming machine uses a certain method of gas into the liquid.
