Working principle and production process of foaming machine

Working principle and production process of foaming machine

Foaming machine, also known as foam generator, is a kind of foaming equipment that uses foaming agent to reach a certain concentration of aqueous solution. So do you know the working principle of foaming machine? What is the production process of the foaming machine? Let ’s take a look together.

  Working principle of foaming machine

  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 are indispensable. Without the foaming agent solution, the liquid film surrounding the gas would not form and there would be no air bubbles. There is no gas, and the foaming agent solution alone cannot form bubbles.

  In the bubble formation system, the foaming agent solution is a dispersion medium, the gas is a dispersed phase, and the gas is dispersed in the liquid to form a bubble, which is then composed of numerous bubbles. 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 liquid must be accomplished by a foaming machine, that is, the foaming machine uses a certain method to introduce gas into the liquid.

  Production process of foaming machine

  1.Feeding and mixing: Add a fixed amount of cement, foaming agent and foam stabilization enhancer to the mixer through the feeding system and dry mix for 30 seconds;

  2. stirring: add a certain amount of warm water to the mixer, wet stirring for 2 minutes; add a certain amount of foaming agent to the mixer and stir for 8-15 seconds;

  3. Injection molding and foaming: The slurry will be injected into the mold to foam, and the foaming process will take about 3-5 minutes;

  4.Initial curing: Allow it to stand for several hours after the completion of injection molding for initial curing;

  5. Demoulding: After the initial setting of the foamed cement insulation board is completed, it can be demoulded when it has the initial strength;

  6. Cutting: The foamed cement insulation board blank with a certain strength can be cut after demoulding, and the cutting specifications can be adjusted according to the needs of the cutting blade;

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

  The above is the introduction of the working principle and production process of the foaming machine. I hope everyone will understand the working principle and production process of the foaming machine, and it will be helpful to everyone.
