中文摘要:

      选择450、500、550、600、650、700℃等不同裂解温度,保持基本一致的进样量(60±1 μg),采用连续升温和分别升温的方法,对聚乙烯及阻燃聚乙烯进行裂解气相色谱(PyGC)分析,比较其性能的差异以及加有不同量阻燃剂的PE的裂解色谱性能.结果表明SiO₂含量不同的阻燃聚乙烯有较明显的阻燃性能,其中SiO₂添加量为%时阻燃效果最好.PyGC的分析结果与锥形量热仪(CONE)的实验结果相一致.

英文摘要:

      The different Pyrolysis-gas chromatography(PyGC) functions of polyethylene (PE) and flame retardant polyethylene at 450℃、500℃、550℃、600℃、650℃ and 700℃ with the same amount of sample by both heating continuously and heating separately were analyzed and compared. The result shows that flame retardant polyethylene contained different amount of SiO₂ has distinct obstraction to buring, especially when the content of SiO₂ is 6% the effect is best.The result of PyGC is the same as that of CONE.
