“水性聚氨酯制备与性能研究”综合性实验的探索
|
摘要
介绍了以科研为导向设计和开设的"水性聚氨酯的制备及其性能研究"综合性化工实验。学生从中体验了查阅文献和讨论、确定实验方案、制备产品、性能表征、数据处理和撰写实验报告等完整的科研过程。实践表明,本实验不仅具有较强的操作性,还具备较好的科研价值,有利于提高学生学习的积极性、主动性和综合实验技能,有利于培养学生的创新能力和科学精神。
A comprehensive chemical experiment on the "Preparation and properties of waterborne polyurethane" which is designed and set up on the basis of scientific research, is introduced. Students may experience the complete scientific research process of consulting literature and discussing, determining experimental scheme, preparing products, characterizing performance, data processing, writing experimental reports, etc. Practice shows that this experiment not only has strong operability, but also has better scientific research value. It is conducive to improving students' learning enthusiasm, initiative and comprehensive experimental skills, and cultivating their innovative ability and scientific spirit.
