以XRF提升水泥樣品主成分之分析效率研究
Enhance the Efficiency of Cement Analysis by XRF
摘要
始於20世紀50年代初，歷經50多年發展的X光螢光分析法已成為物質組成分析的必備方法之一，目前也已廣泛應用於材料分析的各個領域。由於X光螢光分析具高精度、準確性及自動快速等優點，擬利用X光螢光分析儀對水泥進行定量分析試驗。本研究為提升水泥分析效率，以不同形態的製樣方法，如壓片法、熔融法所得的樣品進行分析，並與傳統濕式化學分析法針對分析的成本與效率作一比較。 研究結果顯示，水泥廠以X光螢光分析技術的製樣方法主要有2種：壓片法和熔融法，並從成本、效率上做考量而尋求最適合的儀器分析方法。X光螢光分析的製樣方法以壓片法為水泥廠最通用，其製法簡單、製樣快速、分析成本低；熔融法能有效地消除樣品顆粒效應與礦物效應，而傳統濕式化學分析法的分析時間長、人力成本高。

Beginning in the early 20th century, from the 50s, after 50 years of development, X-ray fluorescence analysis, widely used in various fields of material analysis presently, has become one of the essential methods to analyse material composition. Because of the high-precise, accurate, automatic and fast advantages, etc. of X-ray fluorescence analysis, the researcher used X-ray fluorescence analysis to do quantitative test of cement. In order to enhance the efficiency of cement analysis, this study used different sample preparation methods, such as pressed pellets and fused beads to create two different forms of cement samples for analysis and then compared to the tradtional wet chemical weight analysis in cost and efficiency. The result shows that cement plants which use X-ray fluorescence analysis of cement technology, their sample preparation methods are mainly two kinds: pressed pellets and fused beads, and then in considerations of cost and efficiency, the proprietors will seek the most suitable instrument for analysis. The most common sample preparation method for them is pressed pellets because it is fast and simple in sample preparation and its costs for analysis is low. Meanwhile fused beads can effectively eliminate the sample particle effect and the mineral effect, but the tradtional wet chemical weight analysis has disadvantages in long analytic time and high labor costs.
