Foaming machines very first appeared in foreign countries, their original models may be the use of higher speed rotation on the impeller foam, also referred to as "beating". Later, as technologies advances, foaming machine technologies and constantly strengthen, new models emerge, formed diverse technical systems. Our foam machines in use as early as within the 1950 on the 20th century, however it is not specific foam models, in place of applying mortar mixer. Foaming agent directly into the concrete or mortar mixer blender, foaming agents and mortar or concrete mix to generate foam. Ahead of and soon after within the 1970 on the 20th century, started to have special foaming agent, namely, high speed impeller foam machine. Right after continuous technological upgrading and replacement, has now created EPS cup machine into a high-pressure inflatable for the main body in the third generation model, and may basically meet the requirements of foam concrete.


Operating principle


No matter the foam machines, foam principle could be the air in to the foaming agent resolution. A variety of models of change is definitely the introduction of gas in distinct approaches, and diverse effects.


Foam formation you will discover two critical aspects, is really a foaming agent answer, II air, each are essential. No foaming agent resolution, WPC foam board machine surrounded by gas liquid film would not happen, there will be no air bubbles. Without gas, foam remedy alone, bubbles couldn't kind.


In the program on the formation of air bubbles, foam resolution is the dispersion medium, gas is dispersed, the gas dispersed within a liquid to type bubbles, then created up foam bubbles. In addition to the foaming properties of this critical aspect, introduced gas foaming agent resolution is another significant element. Gas into liquid, must depend on a foam machine to finish, namely foaming machine working with some strategy of bringing gas into the liquid.


Key categories


Foaming machine brands and many models, but from foam theory divides broadly only high-speed impeller type, high stress air, blast with low voltage-type 3. Various points on the same variety, only differences in ancillary devices and automatic PS Foam Sheet Extrusion Line handle, foam part of the structure is largely the same.
