Embodiment Construction
[0041] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0042] Such as figure 1 and figure 2 As shown, it is a schematic structural diagram of the sample preparation device of mineral powder coated with boric acid for XRF detection in this application. The sample preparation device of this application is made by first pressing the mineral powder to shape, and then coating boric acid on the periphery of the shaped mineral powder. Sample to be tested.
[0043] The sample preparation device includes an intermediate mold 100 and two sets of die assemblies 200. Specifically, the intermediate mold 100 has a first channel 100a, and...

The present application discloses a boric acid-coated mineral powder sample preparation device for XRF detection. The sample preparation device includes an intermediate mold and two sets of die assemblies respectively provided at the two opening ends of the first channel corresponding to the intermediate mold. The sample preparation device defines a first chamber for containing mineral powder in the first state The cavity, in the second state, defines the first cavity for accommodating boric acid, and the two sets of die components can move relative to the middle sleeve, so that the die components can be flexibly switched between various states. The boric acid can be compressed and wrapped on the outer surface of the mineral powder in two pressing steps to obtain a sample to be tested with a fixed structure and shape. There is no need to change the position of transferring the mineral cake, and no need to use other structural aids, and the operation is convenient. After the sample to be tested is prepared, the movement of the die assembly is controlled, and the sample to be tested can also be pushed out of the first channel directly, so as to facilitate the transfer of the sample to be tested.
Description
technical field [0001] The present application relates to the technical field of chemical analysis instruments, in particular to a boric acid-coated ore sample preparation device for XRF detection. Background technique [0002] With the development of non-ferrous metal smelting technology and modern information technology, in the non-ferrous metal smelting process, in order to improve the precise control of the smelting process, researchers have more accurate information on the types and contents of the corresponding elements contained in the non-ferrous metal raw ore. According to the research findings, the use of X-ray fluorescence spectroscopy (X-ray Fluorescence, XRF) at this stage can accurately detect the corresponding element types and contents contained in non-ferrous metal raw ore relatively quickly and effectively, and meet the requirements of non-ferrous metal smelting process. demand. [0003] There are many types of mineral powder objects detected by XRF detect...
