摘要
研究了羧酸铈光敏剂及其配合体系的组成、各组分的协同关系和作用,讨论了其配合体系对聚乙烯地膜断裂伸长率、羰基指数和分子量的影响,并进行了农田覆盖地膜应用试验。结果表明,含羧酸铈光敏剂配合体系的聚乙烯地膜具有良好的使用性能和光降解可控性能。
The cerium carboxylate(CeCar) sensitizer system, its composition and synergistic action of components were studied. The effects of CeCar sensitizer system on elongation at break, carbonyl index and molecular weight of LDPE mulch film were discussed. The applicatiion test of LDPE mulch was done, the result showed that LDPE mulch film containing CeCar sensitizer ystem possessed good properties and was photodegradation - controlled.
