| 摘 要： | 以均匀设计试验法制备海藻酸钠/聚乙烯醇水凝胶,应用计算机技术建立原料配比、交联剂浓度、交联时间与凝胶硬度关系的数学模型,分别绘制了硬度与聚乙烯醇、海藻酸钠、氯化钙浓度、交联时间的关系曲线,研究了制备工艺对凝胶硬度的影响.结果表明,影响凝胶硬度的主要因素是交联时间,其次是SA、PVA和CaCl2浓度.

| Abstract: | The uniform design is used and texture analysis is employed to mathematically simulate the effects of PVA and SA proportions,cross-linker(CaCl2) concentrations,and cross-linking time on SA-PVA-C gel hardness.A relational curve between the processing parameters and the gel hardness is established.The result shows that gel hardness is mainly affected by cross-linking time,followed by SA,PVA,and CaCl2 concentrations. |
