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。
The uniform design is used and texture analysis is employed to mathematically simulate the effects of PVA and SA proportions, cross-linker (CaCIa) 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 hard- ness is mainly affected by cross-linking time, followed by SA, PVA, and CaCl2 concentrations.
