聚乳酸的改性与成型加工研究进展

Research Progress on Modification and Molding Processing Technology of PLA

结合生物可降解材料聚乳酸的一些缺点,提出了几种改性的方法,并介绍了聚乳酸成型加工常用的两种方法,即挤出成型和注射成型,最后对聚乳酸的应用进行了展望。

This article put forward several kinds of modified methods based on the shortcomings of bio-degradable poly（lactic acid）,and introduced two methods,extrusion and injection molding methods.Finally the application of poly（lactic acid）was prospected.
