| Summary: | 碩士 === 國立臺北科技大學 === 化學工程研究所 === 99 === 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.
