Main classification. 

There are many grades and models of foaming machine, but according to the foaming principle, there are only three types of foaming machine, such as high speed impeller type, high pressure air type, blast middle and low pressure type and so on. 

The difference of the same type is only the difference between the auxiliary equipment and the automatic control, and the structure of the foaming part is roughly the same. 

Production process. 

1. Feeding and mixing: through the feeding system, the quantitative cement, foaming agent and foam strengthening agent are added to the mixer and mixed for 30 seconds. 

2. Stirring: add the quantitative warm water to the mixer and stir wet for 2 minutes, and add the quantitative foaming agent to the blender for 8-15 seconds. 

3. Injection and foaming: the slurry is immediately injected into the mold for foaming, and the foaming process is about 3-5 minutes. 

4. Initial maintenance: after the injection mold is completed, the mold is left to rest for several hours for initial maintenance; 

5. Demoulding: the foamed cement insulation board completes the initial setting and can be demoulded when it has the initial strength. 

6. Cutting: the blank of foamed cement insulation board with certain strength can be cut after demoulding, and the cutting specification can be adjusted according to the need. 

7. Finished product maintenance: the curing age of foamed cement insulation board should not be less than 7 days. 

There are many kinds of cyclopentane foaming machines on the market, there are numerous foaming machines of various brands, shapes and names, and the foaming machines of new brands and new names are still being launched. 

A large number of models, so that producers dazzled, so that the wrong model, in order to facilitate producers to correctly choose foaming machine, now talk about the selection method of foaming machine. 

Fully understand the types of foaming machines. 

Although the basic principle of foaming machine is to introduce gas into the aqueous solution of foaming agent, different types of foaming machines introduce gas in different ways. 

Know the type of foaming machine to know its air entraining mode, which is of great help to further understand its technical characteristics and performance, and help producers to grasp the overall. 

For example, the low speed stirring type introduces the gas by the slow rotating blade, the bubble yield is small and the foaming efficiency is low, and the high speed impeller is induced by the high speed rotating impeller, the bubble diameter can not be controlled and the foam is uneven. 

The bubble formation rate of high pressure and medium and low pressure is fast, the efficiency is high, and the bubble is uniform and fine. 

After knowing the advantages and disadvantages of each type of foaming machine, it is easy to choose the foaming machine. 

Therefore, a full understanding of the type of foaming machine plays an important role in the correct selection of foaming machine.
