The basic principles of foaming are the same whether it is rock wool spray foaming machine, PU foaming machine, pentane foaming machine or other types of foaming machines.

First, air is introduced into the foaming agent solution. The change of different types of foaming machines is that the way of introducing the gas is different, and the foaming effect ultimately caused is also different.

There are two necessary factors for a foaming machine to form foam. The first is the foaming agent solution, and the second is air. Without the foaming agent solution, the liquid film around the gas will not form and no bubbles will be generated. There is no gas, only the foaming agent solution is present, and no bubbles can be formed.

In the bubble formation system, the foaming agent solution is the dispersion medium and the gas is the dispersed phase. The gas is dispersed in the liquid to form bubbles, and the bubbles are composed of numerous bubbles. In addition to the important factor of foaming agent performance, the introduction of gas into the blowing agent solution is another important factor.

The introduction of gas into a liquid by a foaming machine must be completed by a foaming machine, that is, the foaming agent itself cannot automatically become a foam, and must be mechanically activated by the foaming machine to become a foam. Therefore, the foaming machine is also called a foam generator.
