摘要
本文研究了可溶性淀粉与PVA的混溶性 ,探讨了可溶性淀粉与PVA的比例 ,PVA的聚合度和醇解度对分离速度的影响及混合体系的混合比和机械强度的关系。实验结果表明 ,聚乙烯醇的醇解度对平衡状态的分离极限无影响 ,可溶性淀粉的聚合度对混溶性的影响比PVA聚合度的影响大。
In this paper,the miscibility of soluble starch and PVA,the effect of polymerization degree and alcoholysis degree of PVA on separation speed of system and the relation of mixing ratio of the mixed system were investigated.Experimental results showed that the alcoholysis degree of PVA did not affect the separation limit of the steady state and the polymerization degree of soluble starch affected the miscibility more than that of PVA.
