Embodiment 1

[0030] Select the raw material alumina to be tested, add the alumina into an agate mortar and grind it into powder and sieve it, collect a sample with a particle size of 150 mesh, and then pass the mass ratio with the binder to a ratio of 1:3. After weighing, pour it into the tablet press mold, adjust the tablet pressure of the tablet press to 225KN, and start pressing the sample after the pressure holding time is 25s, and use the pressed sample for X-ray fluorescence spectrometer detection.

Embodiment 2

[0032] Select the raw material feldspar to be tested, add the feldspar into an agate mortar and grind it into powder and sieve it, collect a sample with a particle size of 75 meshes, and then pass the mass ratio of 3:1 with the binder. After weighing, pour it into the mold of the tablet press, adjust the tablet pressure of the tablet press to 200KN, and start to press the sample after the pressure holding time is 50s, and use the pressed sample for X-ray fluorescence spectrometer detection.

Embodiment 3

[0034] Select the raw material silica sand to be tested, add the silica sand into an agate mortar and grind it into powder and sieve it, collect a sample with a particle size of 100 mesh, and then weigh it with the binder in a ratio of 2:1 by mass. After the weight is poured into the tablet press mold, the tablet pressure of the tablet press machine is adjusted to 250KN, and the pressure holding time is 30s, and then the sample is pressed, and the pressed sample is used for X-ray fluorescence spectrometer detection.

Abstract

The invention relates to a glass raw material tabletting method suitable for analysis of an X-ray fluorescence spectrometer. The method is characterized by comprising the following steps: (1) preparing a glass raw material to be detected; (2) grinding the glass raw material, sieving after grinding, and controlling the granularity to be 50-200 meshes; (3) mixing a glass raw material with the mesh number of 50-200 and a binder according to the mass ratio of 1: 1-5: 1, wherein the binder is any one of boric acid, methyl cellulose, polyethylene and the like; (4) feeding the raw materials mixed in the step (3) into a tablet press for tabletting, controlling the pressure of the tablet press to be 200-300KN, keeping the pressure for 20-60s, and starting to press a sample; and (5) detecting the pressed sample by using an X-ray fluorescence spectrophotometer. The method has the advantages that the binder is added before tabletting, so that the tabletted sample is smooth in surface and free of cracks, and the sample injection requirement of X-ray fluorescence spectrophotometer detection equipment can be met; powder forming is more efficient, and the sample detection efficiency is improved; and powder forming is more stable, and use safety of equipment is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of instrument analysis, and relates to the field of X-ray fluorescence spectrometer analysis, in particular to a glass raw material tabletting method suitable for X-ray fluorescence spectrometer analysis. Background technique [0002] In the production of glass industry, raw material quality, composition analysis, intermediate control, etc. all need to use analytical methods. In traditional chemical analysis methods, the analysis process is mostly long, and the analysis needs to be completed through multiple processes such as sampling, sample preparation, sample fusion, and sample measurement. The workload of the analyst is very large, and the analysis cycle of a single element takes 1-2 For the urgent production situation, this method is not suitable; when the concentration of an element in the raw material is large, the measurement of the element is not suitable for plasma emission spectrometry (ICP), and ...
