Identification of the zinc dispersion in rubber blends by libs with a Nd: YAG laser

  • 摘要: 激光诱导击穿光谱是一种基于激光的定性、定量分析化学元素的方法,可用于分析混合室中的橡胶共混物。本文采用波长为1 064 nm、脉冲能量为100 mJ的Nd: YAG激光诱导击穿光谱法检测橡胶共混物中锌的分散情况。实验表明,正确混料决定了橡胶产品的质量,较短的混合时间将会导致混料的不均匀分散;焦距等参数设置对光谱线强度影响较大。激发标定样品可产生标定曲线。通过行扫描可分析锌在橡胶共混物中的分散情况。通过估算沿着行扫描方向的强度分布,可检测由于混合时间较短和旋转速度不同而引起的锌均匀性变化。
