Foaming Machine, also known as bubble generator is the easiest to do foam cement equipment.
  Foam blowing machine is able to make a certain concentration of aqueous foam equipment. foaming agent itself is not automatically become a bubble, it must go through the mechanical action of foaming machine in order to become a bubble. Foam machines and blowing each other with a technical system alone can not play a role. Foam machine foam itself can not output to a vacuum, it is blowing into the air dispersed in aqueous solution, to achieve liquid-gas contact surface as large as possible, so that the surface active foaming agent in the surface material in the film The formation of electric double layer and surrounded by air, forming a bubble. The main body of foam concrete foam, foam bubble machine and thus the system has become the key to the production of foam concrete equipment and host. Without it, there is no foam concrete. Foaming Machine first appeared in foreign countries, the original model is the use of high-speed rotating impeller system of bubbles, also known as "playing the bubble machine. "
  Later, as technology progresses, the foam machine technical content continues to increase, the new models continue to emerge, forming a different technology systems. In the early 50's in the 20th century began the use of foam machine, foam models, but not exclusively, instead of using the mortar mixer. Be blowing directly into the mortar mixer or concrete mixer, so that foam and mortar or concrete mixing together generate foam.
  After 70 years of the 20th century, began to appear special foam, foam machine that high-speed impeller. And later constantly upgrading and updating of technology, has now developed into a high-pressure inflation as the main body of the third generation of models to meet the basic needs of foam concrete. Foam machine brands and models a lot, but the foam divided by principles, are now widely used, only high-speed impeller type, high-pressure air type, blast type low-voltage three categories. The same type of difference, but their associated equipment and automation control differences in the structure of some of substantially the same foam.
