What is a foaming machine? What is the principle?

1. Define a machine for injecting raw materials that can generate plastic foam into the gap between the container and the contents of the lining film during the product packaging process, and forming a foam buffer material that tightly wraps the contents through chemical reaction. Second, the principle of foaming machine is that a foaming agent can be made into foaming machine with a certain concentration of aqueous solution. The foaming agent itself cannot be automatically turned into foam, but can only be turned into foam through the mechanical action of the foaming machine. Foaming machine and foaming agent are a technical system that cooperates with each other and cannot function independently. The foaming machine itself cannot produce foam out of thin air. It introduces air into the foaming agent aqueous solution and disperses it evenly, so as to maximize the liquid-gas contact surface and make the surfactant in the foaming agent form an electric double layer on the surface of the liquid film and surround the air to form bubbles. The main body of foam concrete is foam, so the foaming machine for making foam becomes the key equipment and main machine for foam concrete production. Without it, there would be no foam concrete. The stock solutions of component A and component B are accurately proportioned and stirred at high speed, and the feed solutions of component A and component B are respectively delivered to the stirring head by two high-precision metering pumps. After high-speed and strong stirring, the feed liquid is sprayed evenly to form the required product.
