物理发泡剂

超临界CO2流体作为物理发泡剂，通过发泡对聚乙烯醇薄膜进行致孔。

Using SC-CO_2 as a foamer make pores in the dry polymer .

特别是采用CO2，N2等惰性气体作为物理发泡剂的发泡方法因其符合环保的要求，日益受到重视。

Particularly the physical foaming use of inert gas as CO2 N 2 meet environmental protection requirements , is payed more attention .

用物理发泡剂制备韧性泡沫硅橡胶

Molding of Cellular Silicone Elastomer with Physical Foaming Agent

用物理发泡剂制备了具有特殊性能要求的韧性泡沫硅橡胶，重点介绍了原材料预处理、成型技术及加工工艺参数等。

The cellular silicone elastomer with special property and structure was molded with physical foaming agent .

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 show that the more enhancing the bubble nucleation and the larger the amount of the foaming agent , the smaller the bubble cell size .

是利用物理发泡剂的压力能或化学发泡剂受热分解所释放出的化学能引发常规机械分散方法所难以获得的高拉伸场。

The strong stretching field can be formed by using the pressure energy of physical inflating agent or chemical energy released by decomposing chemical inflating agent when heated , which can not be obtained by conventional mechanical dispersion method .
