摘　　要：为满足消防安全领域中灭火剂产品质量的快检需求,提出了一种近红外漫反射光谱快速测量ABC干粉灭火剂主要有效成分磷酸二氢铵(NH4H2PO4)及识别ABC干粉灭火剂与BC干粉灭火剂的新方法。采用多元校正PLS方法建立了ABC干粉灭火剂磷酸二氢铵含量校正模型,RMSECV=2.1,RMSEP=2.4。采用SIMCA方法建立了ABC/BC干粉灭火剂识别模型,分辨准确率百分之百。与现行标准方法相比,该方法具有快速,操作简单等优点,非常适合于消防产品的现场质量检测。A new quantitative method to determine the NH4 H2 PO4 in ABC powder extinguishing agent and to distinguish between ABC and BC powder extinguishing agents using near infrared diffuse reflectance spectroscopy is proposed. A PLS calibration model for the NH4 HzPO4 content in extinguishing agent powder was established, with RMSECV=2.1, RMSEP=2.4. An identification model for ABC and BC powder extinguishing agents was built by SIMCA and the identification accuracy rate is 100%. This method, compared to the present standard method, has the characteristics of rapidness and easy operation, whichis fit for the quantitative analysis and type distinguishing of the fire products on site.
