摘要
以氯化铬和草酸钠为原料合成了一种交联剂,以草酸根为配体与Cr^(3+)络合,考察交联剂与部分水解聚丙烯酰胺(HPAM)的凝胶交联性能。考察了交联剂的摩尔比、交联剂与HPAM的交联质量分数、交联温度和体系pH值对凝胶性能的影响。
Abstract:A crosslinking agent was synthesized used chromium chloride and sodium oxalate as raw materials.The crosslinking properties of crosslinking agent and partially hydrolyzed polyacrylamide(HPAM)gel were investigated by complexation of oxalate ligand and Cr3+.The effects of different molar ratio of crosslinking agents,crosslinking mass fraction of HPAM,crosslinking temperature and pH on the properties of crosslinking agent were also investigated.
