The working principle of the foaming machine is introduced in detail

Foaming machines have appeared in foreign countries for a long time, and their original models used impellers to rotate at a high speed to make foams, so they are also called 'foaming machines'. Later, with the continuous advancement of technology, the technical content of the foaming machine continued to increase, and new models continued to appear, forming a different technical system. my country began to use foaming machines as early as the 1950s, but instead of special foaming models, mortar mixers were used. That is, the foaming agent is directly added to the mortar mixer or concrete mixer, and the foaming agent is mixed with the mortar or concrete to generate foam. Around the 1970s, special foaming agents, namely high-speed impeller foaming machines, began to appear. In the future, the technology has been continuously upgraded and replaced, and it has now developed into a third-generation model with high-pressure inflation as the main body, which can basically meet the needs of foam concrete. 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 cannot form bubbles. In the bubble formation system, the foaming 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 numerous bubbles form the foam. 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 done by the foaming machine, that is, the foaming machine adopts a certain method to introduce the gas into the liquid.
