低烟无卤材料的卤素含量检测方法

Detection Method for Halogen Content in LSFH Materials

在电线电缆行业中,材料的卤素含量检测主要采用GB/T 17650的方法,但是该标准中的返滴定法、pH法、电导率法均不能对低烟无卤材料的微量卤素进行定性和定量的检测分析,而离子色谱法可定性、定量地对低烟无卤材料中微量卤素进行测定。这为后续完善国内检测无卤材料标准提供了基础。

In wire and cable industry,GB/T 17650 is usually used to detect the halogen content in wire and cable materials,but the methods listed in this standard can't detect and analyze the trace halogen content in LSFH materials qualitatively and quantitatively.The ion spectrum method is used to qualitatively and quantitatively detect and analyze the trace halogen content in low smoke free of halogen(LSFH)materials,and it provides a foundation for improving GB/T 17650.
