LOI Oxygen Index 氧指数试验
Experimental data were obtained by means of all kinds of instruments such as a tensile machine, an Izod impact test machine, thermogravimetric analysis, limit oxygen index (LOI) instrument and so on.
各种数据的获得借助于拉力试验机、悬臂梁冲击试验机、热重分析仪、和氧指数仪等各种分析测试手段。
Thermal gravimetric analysis(TGA), FTIR, Limited oxygen index(LOI) and vertical firing test are used to research the flame retardancy of the intumescent flame retardant on PP.
采用热重分析（ TGA）、红外光谱分析（ FTIR）、 氧指数测定和垂直燃烧实验，研究了所合成的膨胀型阻燃剂对聚丙烯的阻燃作用。
Its limiting oxygen index (LOI) value was over 50, which further promoted its flame retardant effect and its value for practical USES.
限氧指数值高达50以上，进一步提高了阻燃效果及其实用价值。
