5Foam is now used in many packaging, which plays a cushioning role to prevent the package from being damaged by external mechanical force.
Foam is made by foam molding machine. Do you know the working principle of foam molding machine? Let's take a look with the manufacturer of the automatic molding machine.
1、 Definition of foam forming machine
In the process of product packaging, the raw materials that can produce plastic foam are injected into the gap between the container and the contents of the film, and foam cushioning materials are formed through chemical reaction.
2、 Working principle of foam forming machine
Foam will not appear out of thin air, it must be produced by special process of foaming equipment.
Foaming equipment is the equipment that can make foam from certain concentration of aqueous solution (foaming agent).
Foaming agent itself cannot automatically become foam. It can become foam only through the mechanical action of the foaming machine.
The foaming equipment itself cannot produce foam out of thin air. Introduce air into the foaming agent aqueous solution, disperse evenly, and achieve the contact surface between liquid and gas as much as possible, so that the surface active substances in the foaming agent form a double layer on the surface of the liquid film, surrounding the air and forming bubbles.
The foaming machine and foaming agent are a technical system that work together and cannot function independently.
