At present, mature sample slice preparation technologies comprise a method for preparing a glass slice by melting borate, a method for preparing a metal slice by remelting in an induction furnace and a method for tabletting powder. Wherein, the powder tabletting method has wide application due to high speed and low cost of preparing the sample tablet; in the tableting analysis, the particle size of the test piece powder has a large influence on the analysis result, the tableting rate of the compressed tablet and the strength of the test piece.
In order to improve the accuracy of the analysis results and reduce the effect of particle size, the influence of particle size effect on X-ray fluorescence spectroscopy analysis of sintered ore [ J ] metallurgical analysis, 2006, 26 (3): 92-93) and document 2 (Liu Sha, etc.. the influence of particle size of sample powder processing on the analysis results was studied using a tabletting method with an X-ray fluorescence analyzer for analyzing clinker components [ J ] cement technology, 2004(6):96-99), and an appropriate particle size and appropriate processing method suitable for each of the samples were found, although the preparation process was simplified with respect to melt tabletting, the sample loading speed was still slow with respect to tabletting technology with a fast tabletting speed in tabletting with boric acid substrate hemming; in the tabletting method using the plastic ring, the amount of the sample powder and the effective pressed sample powder cannot be controlled, and the tabletting efficiency and the strength of the sample are affected.
