    What is the principle of Zhengzhou foam board foaming?

    Zhengzhou foam board is a common packaging product, which is made by foaming and curing composite processing of foamed EPS beads and phenolic resin in the presence of curing agent and foaming agent. So what is the principle of foaming Zhengzhou foam board? How is it formed? Let's take a look at it.

    1. The process of bubble core formation
    The bubble nucleus is an embryo that generates bubbles, and it is a place where gas-phase molecules begin to ash machine in a polymer melt or liquid. After the EPS beads are added, the bubble core is formed on the surface of the beads, so it is said that its function is an accelerator, which can increase the number of bubble cores. The cells of the produced Zhengzhou foam board are relatively uniform, and all indicators Relatively excellent.
    2. Bubble growth stage
    The gas pressure in the small bubbles of the Zhengzhou foam board is relatively large. When the small bubbles meet, they merge into large bubbles, which can reduce the pressure of the gas in the bubbles.
    3. The stable phase of the bubble
    The volume and surface area of Zhengzhou foam board will become larger and larger as the bubble grows, the bubble wall will become thinner, the foam body will be unstable, and some of the cells will be shaped as the bubble continues to grow. And the merger, fragmentation and gas escape phenomena will occur during the growth of the cells of Zhengzhou foam board.
