preparation example Construction

[0012] A method for preparing a fluorescence analysis grinding aid, comprising the following steps:

[0013] 1) Weigh the raw materials by mass percentage, and then mix them uniformly;

[0014] 2) Press the uniformly mixed raw materials into a flake grinding aid.

[0015] In the preparation method of the above-mentioned fluorescence analysis grinding aid sheet, the mass percentages of the raw materials in step 1) are: rosin powder 5-30%, starch 30-60%, polyvinylpyrrolidone 5-30%, methylcellulose 5-30%. 30% and zinc stearate 3-20%.

[0016] In the above preparation method of the fluorescence analysis grinding aid, the diameter of the grinding aid in step 2) is 8-16 mm, the thickness is 3-6 mm, and the weight is 0.3-0.8 g.

[0017] Among the above raw materials, rosin powder mainly plays a decisive role in aiding grinding, starch is a tableting auxiliary material, polyvinylpyrrolidone and methylcellulose are a kind of binder for pressing pharmaceutical tablets, and are also bi...

Embodiment 1

[0020] After mixing 60% of starch, 20% of rosin powder, 5% of polyvinylpyrrolidone, 5% of methylcellulose and 10% of zinc stearate, use a tablet machine to press into a tablet shape, and prepare a diameter of 10mm and a thickness of 3mm. Grinding aid sheet weighing 0.3g.

Embodiment 2

[0022] After mixing 50% starch, 20% rosin, 10% polyvinylpyrrolidone, 10% methylcellulose and 10% zinc stearate, use a tablet machine to press into a tablet shape, and prepare a diameter of 12mm, a thickness of 3mm, and a weight of 0.3 G grinding aids.

Abstract

The invention belongs to the field of fluorescence analysis, and particularly relates to a grinding aid sheet for fluorescence analysis and a preparation method thereof. The invention aims to solve the technical problem that the inaccurate addition amount of the grinding aid can easily cause deviation of the analytic result and is not beneficial to controlling the production quality. In order to solve the technical problem, the invention provides a grinding aid sheet for fluorescence analysis, which is prepared from the following raw materials in percentage by mass: 5-30% of rosin powder, 30-60% of starch, 5-30% of polyvinylpyrrolidone, 5-30% of methyl cellulose and 3-20% of zinc stearate. The grinding aid sheet provided by the invention is beneficial to enhancing the work efficiency, lowering the labor intensity and enhancing the data accuracy, and has promotion actions on enhancing the production quality control level.

Description

technical field [0001] The invention belongs to the field of fluorescence analysis, in particular to a fluorescence analysis grinding aid and a preparation method thereof. Background technique [0002] During the fluorescence detection process, there are many factors that affect the accuracy of the analysis results, the most important of which is the sample preparation method. For example, in the cement industry, fluorescent sample preparation methods include melting tablet method and powder pressing method. Due to the high cost and slow speed of the melting tablet method, and the fast speed, low cost and convenient operation of the powder tableting method, cement enterprises generally adopt the powder tableting method. However, there are unavoidable particle size effects and mineral mineral effects in the powder tableting method (the phenomenon that the intensity of x-rays varies with the particle size of the sample and the inhomogeneity of the sample is called the particl...
