增加凝胶渗透色谱法用扩孔硅胶强度的研究

Studies of the Increasing Strength of Reaming Gel for GPC

首次采用硅酸钾水溶液浸涂法提高硅胶的强度。找出了浸涂硅酸钾水溶液后的孔容、强度和浸涂次数的关系，为制备适用于大分子量高聚物的分子量分布的高强度、高效率的ＧＰＣ担体提供可靠的依据。

The strangth of Gel is raised by firstyl uaing aqueous potassium silicate. After dip-coating aqueous potassium silicate,we find out the relations of hole capacity,strength and numbers of dip coating,which supply a precise basis for preparing GPC supporter for distribution of melecular weight of polymer of high melecular weight with high-intensity and high effenciency.
