Working principle of foam molding machine
Foam is now used in many packaging to act as a cushion to prevent the packaging from being damaged by external mechanical forces. The foam is made by a foam forming machine. Do you know how a foam forming machine works? let us see.
First, the definition of foam molding machine
When used for packing products, the raw materials that can generate plastic foam are injected into the gap between the container and the contents of the lining film, and the foam buffer material is formed by chemical reaction.
Second, the working principle of foam molding machine
Bubbles do not arise out of thin air. It must be manufactured by the special process of foam equipment. Foaming is a device that can make foam from a certain degree of aqueous foaming agent (foaming agent). Foaming itself cannot automatically become foam, it must be turned into foam by the mechanical action of the foaming machine. The foaming equipment itself cannot generate foam. It introduces air into the foaming agent, disperses the water evenly, realizes the surface active substance with possibly larger liquid-gas contact surface, forms an electric double layer on the surface of the liquid film, surrounds the air, and forms bubbles. Foaming machine and blowing agent are a technical system. If they don't work, they must be produced with a blowing agent.
