【摘要】 本文对热交联,氢氧化钠交联及辐射交联聚乙烯醇膜的溶胀行为进行了研究。整个选择性渗透过程被分解成选择溶解和选择扩散两部分。本文定义了选择溶解因子和选择扩散因子,用以评价上述两部分各自对渗透气化过程的贡献。更多还原

【Abstract】 The swelling process of the heat, alkali~-, and radiation crosslinked PVA membraneswas investigated. The pervaporation process was divided into two parts: selective sorptionand selective diffusion. The contribution of the two parts respectively into the pervaporationwas evaluated with the selective sorption factor and the selective diffusion factor.更多还原
