溶剂刻蚀法测定聚乙烯交联结构

Determination of crosslinked structure of ethylene by solvent erosion method

以四氯化碳溶液和三氯甲苯溶液为溶剂对交联聚乙烯的表面结构和断面结构进行刻蚀处理,采用扫描电镜对聚乙烯的交联结构进行观察。结果表明,聚乙烯断面结构经三氯甲苯溶液刻蚀50h处理后,可清晰地观察到其交联结构。

Carbon tetrachloride solution and trichlorotoluene solution were used for erosion treatment of surface structure and cross section structure of crosslinked polyethylene, and scanning electron microscope were used for observing the crosslinked polyethylene. The result showed the crosslinked structure of polyethylene could be observed clearly after 50h treatment of it's cross section structure by trichlorotoluene solution erosion.
