The results show that the more enhancing the bubblenucleation and the larger the amount of the foaming agent, the smaller the bubble cell size.
研究结果表明:气泡成核数越大,物理发泡剂的含量越高,泡孔半径越小;

The results showed that the imposed vibration may increase effectively the bubblenucleation rate, which was better than that via increasing rotation speed.
实验发现,提高转速可以提高熔体的剪切应力,从而提高气泡成核率,但不如施加振动效果明显。

After analyzing the physical process of polyurethane foam formation, such conclusions can be got: bubblenucleation and bubble growth affect cell size primarily.
