摘要
通过热固性硅树脂膜的控制裂解和活化，开发出一种新型的可用于高温气体分离的硅膜。热固性硅树脂的化学组成及其结构，裂解及活化条件是影响最终生成的高温气体分离用硅膜性能的关键因素。和常规无机膜及有机膜相比较，分子筛硅膜具有优异的选择透过性能，和分子筛炭膜相比较，硅膜突出的优点是具有优异的耐高温氧化性能，因而这种膜在高温含氧混合气的膜法分离方面，具有广泛的应用前景。
A new silicon membrane, which is employable in gas separation at higher temperature,is developed by control pyrolysis and activation of a thermosetting.silicon resin membrane. The chemical structure and composition, the conditions of pyrolysis and activation of the thermosetting silicon resin are the key factors which affect properties of the resulted silicon membranes. The molecular sieve silicon membranes have outstanding permselectivities as compared with common organic and inorganic membranes.The superiority of the silicon membrane is its higher heat resistance in comparison with carbon molecular sieve membrane.The silicon membranes also have a broad prospect to be applied in membrane separation of gas mixture at higher temperature.
