    Zhengzhou Foam Factory talks about the maturation of foam

    Source: http://cz-invest.com/news/491.html Published: 2019-10-11

    Foam is still a relatively common product in life. Zhengzhou Foam Factory believes that he can be seen in many places, but many people do not know about foam. Today Zhengzhou Foam Factory takes everyone to understand the maturation of foam.

    Zhengzhou Foam Factory introduced that during the foam curing process, the foam beads are cooled by air, and the blowing agent and water vapor in the pores of the cells are condensed into a liquid, so that a vacuum is formed in the cells. At the same time, the air penetrates into the inside of the cells through the cell membrane, so that the pressure in the cells is balanced with the external pressure, which will make the beads after the pre-emphasis more elastic. External diffusion, so Zhengzhou Foam Factory recommends that the reservoir time after pre-flight is not too long.
    Water absorption is an extremely important technical index for foam boards. When producing perfect insulation materials such as foam boards, Zhengzhou Foam Factory needs to strictly control the water absorption of foam boards.
    Zhengzhou Foam Factory believes that high water absorption will lead to poor insulation performance. Over time, its insulation layer will lose its effect, further causing the insulation structure layer to be renovated. In order to reduce the water absorption rate, Zhengzhou Foam Factory made adjustments to the product structure. The new foam board has a complete closed-cell structure. The closed-cell structure can effectively prevent the penetration of water molecules (including water vapor), even during construction. Mechanical damage can also effectively maintain the low water absorption function due to the tight and tight honeycomb structure.
