A Novel Method for Identifying the Main Component of Phosphate Powder

[[abstract]]多效磷鹽乾粉滅火器，在消防安全設備中通稱為ABC乾粉滅火器。此類乾粉滅火器適用於搶救A、B、C類火災。多效磷鹽乾粉現行依「滅火器用滅火藥劑認可基準」規定以CNS 8450〔肥料檢驗法-磷之測定〕方式檢驗。此檢驗方式可確定多效磷鹽乾粉滅火器中是否有存在磷的成份，並不能直接檢驗是否有存在磷酸二氫銨。滅火器用滅火藥劑認可基準對於第二大主成分之硫酸銨的成分及比重，亦無規範相關之檢驗方法。 本研究使用高效能同步熱重熱焓分析儀(TGA/DSC)運用熱分析方法以及傅立葉轉換衰減全反射紅外光譜法(ATR-FTIR) ，成功建立一直觀之成份驗證方法。此成分驗證方法可有效確認多效磷鹽乾粉主成分之存在，可以用以補充傳統檢驗方法之不足。[[abstract]]Phosphate powder fire extinguishers is well known as ABC powder fire extinguisher It is suitable for A B C type fires According to the Basic Specifications of Approval to Extinguishing Agent of Fire Extinguishers the content specifies that the principal components of agent shall conform with the inspection mode of the CNS 8450-1992 Method of Test for Fertilizers–Determination of Phosphorus Content Moreover the regulatory test method actually only inspects the ammonium dihydrogen phosphate content by an indirect method of determining its phosphorous content The second main component of phosphate powder ammonium sulfate is not required in the Basic Specifications of Approval to Extinguishing Agent of Fire Extinguishers It is not required in other regulatory either This study uses Simultaneous Thermal Analyzer (TGA/DSC) and Attenuation Reflectance Fourier Transformation Infrared Spectrometry(ATR-FTIR) to found a direct determination of Phosphorus Content This method can confirm the existence of the main content of phosphate powder It can remedy the shortcomings of traditional test method
