Foaming machine, also known as foam generator, is a kind of foaming agent to reach a certain concentration of aqueous solution to make foam equipment. 

Foaming agent itself can not automatically become foam, must be through the mechanical action of the foaming machine in order to become foam. 

working principle. 

No matter what kind of cyclopentane foaming machine, the basic principle of foaming is to introduce air into the foaming agent solution. 

The change of various models lies in the different ways in which gas is introduced, so the effect is also different. 

There are two necessary factors for the formation of foam, one is the foaming agent solution, the other is air, both of which are indispensable. 

Without a blowing agent solution, the liquid film that surrounds the gas will not form, and there will be no bubbles. 

If there is no gas, there is a solution of foaming agent, and the bubble can not be formed. 

In the bubble formation system, the foaming agent solution is the dispersion medium, the gas is the dispersed phase, the gas is dispersed in the liquid, can form the bubble, and then by the innumerable bubble to form the foam. 

In addition to the important factor of foaming agent performance, the introduction of foaming agent solution by gas is another important factor. 

The introduction of gas into the liquid must be completed by the foaming machine, that is, the foaming machine uses a certain method to introduce the gas into the liquid. 

History of development. 

Foaming machine first appeared in foreign countries, its original model is the use of impeller high-speed rotation foam, also known as "foaming machine." 

Later, with the continuous progress of technology, the technical content of the foaming machine continues to improve, new models continue to appear, forming a different technical system. 

China began to use the foaming machine as early as the 1950s, but it is not a special foaming machine, but a mortar mixer. 

The foaming agent is added directly to the mortar mixer or concrete mixer, and the foaming agent is mixed with mortar or concrete to form foam. 

Around the 1970s, there began to be a special foaming agent, that is, high-speed impeller foaming machine. 

After that, the technology has been continuously upgraded and replaced, and now it has developed into the third generation model with high pressure inflation as the main body, which can basically meet the needs of foam concrete.
