【摘要】 研究了胶原蛋白膜的抗张强度和断裂伸长率与膜中各组成成份含量之间的关系。胶原采用适当条件下的 1.5小时的胶原提取成份 ;采用 0 .2 2 %～ 0 .2 7%的戊二醛为交联剂 ;以 0 .4 %～ 0 .6%的淀粉作为定型剂 ;增塑剂用量以 0 .2 5%为最佳更多还原

【Abstract】 The relationship of the tensile strength, elongation at break of the collagen film and the contents of each components were studied. The collagen is abstracted from the waste scraps of bovine hide by suitable hydrolytic degradation method for 1.5 hours. Test showed that good results would be obtained if making 0.22%~0.27% glutaric dialdehyde as the main crosslinking agent, 0.4%~0.6% starch as the fixing agent.And the optimum amount of the plasticising agent is about 0.25%.更多还原
