利用CT技术研究了通过溶析成孔法、化学发泡法和混合发泡法制得的硅橡胶泡沫材料的泡孔结构,并对影响泡孔结构的因素进行了分析。结果表明,成孔方法对硅橡胶泡沫材料的泡孔结构有重要影响,通过不同成孔方法可以获得不同泡孔结构的硅橡胶泡沫材料。
The cell structure of the silicone rubber foam obtained by the method of melt-forming, chemical foaming and mixed-foaming was studied by using the CT technique. The factors affecting the cell structure were also analyzed. The results show that the pore-forming method has an important influence on the cell structure of the silicone rubber foam. Silicone rubber foam with different cell structure can be obtained by different pore-forming methods.
