    What is the foaming method of foam plastic in Zhengzhou Foam Factory

    In our daily life, the use of foamed plastics is very common. Foamed plastics are based on a synthetic resin with foaming agents and other additives added to form a substance with a fine-pore plum-like structure through foaming. Commonly used resins are Polyethylene, polystyrene, polyvinyl chloride, polypropylene, polyurethane, etc. So, what is the foaming method of foam plastic? The following Zhengzhou Foam Factory will introduce you.

    1. The foam board can effectively eliminate the "thermal bridge" in the past. Inner insulation is inevitable. The "thermal bridge" is inevitable, and the external wall insulation effectively prevents the generation of thermal bridges and avoids condensation. Insulation, because the structural layer with greater heat storage capacity of the wall is inside the wall, it is conducive to the stability of the room temperature.
    2. Chemical foaming method This method uses strong mechanical stirring to entrain air into the resin emulsion. The suspension or solution becomes a uniform foam, and then undergoes physical or chemical changes to gel and solidify into a foam plastics department. In order to shorten the time, air can be added and emulsifiers or surfactants can be added. Commonly produced by this method are polyformaldehyde, polyvinyl formal, polyvinyl acetate, polyvinyl chloride sol and other foam plastics.

    From the above introduction of Zhengzhou Foam Factory, we can see that the commonly used foaming methods are physical foaming method, chemical foaming method and mechanical foaming method.The resulting bubble structure is divided into two types: one is independent bubbles, also known as closed cell structure Each bubble has a thin-walled independent shape; the second is connected bubbles, also known as an open-cell structure, and each bubble is connected to one another.
