Problems solved by technology

SiO in traditional cement clinker 2 The chemical analysis method (GB175-2006) has been used for component analysis for a long time. Although this method has high accuracy and good stability, the operation is cumbersome, labor-intensive, and work efficiency is low. It takes 3 hours to analyze a sample, which is not suitable for current production ingredients. requirements

Embodiment Construction

[0015] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] A rapid determination of SO in cement clinker 2 The method of content comprises the following steps:

[0017] (1) Add grinding aid to the cement clinker sample to be analyzed and grind;

[0018] (2) Press the sample after grinding. Generally, after holding the pressure for 60 seconds, the sample can be firmly bonded, and the X-ray fluorescence spectrometer (PANalytical, Axios type) is used to measure the fluorescence intensity of the Si element in the sample;

[0019] (3) According to the working curve, the SiO in the sample is obtained 2 mass percent.

[0020] Selection of grinding aids (added by 2wt% of clinker):

[0021]

[0022] As can be seen from the above results, the effect of the grinding aid...

Abstract

The invention discloses a method for rapidly measuring content of SO2 in cement clinker. The method comprises the following steps: (1) a grinding aid is added into a cement clinker sample to be analyzed and grinding for 3-4 min, wherein the grinding aid is a mixture of stearic acid and triethanolamine; (2) tabletting the ground sample, loading the sample onto an X-ray fluorescence spectrometer and measuring to obtain fluorescence intensity of the Si element in the sample; and (3) obtaining mass percentage of SiO2 in the sample according to a working curve of fluorescence intensity and content. In comparison with a traditional method, the method provided by the invention has advantages as follows: analysis time is greatly shortened; detection time of a sample is reduced to 10 min from traditionally 3 h; analysis speed is raised; and labor intensity of operators is greatly reduced.

Description

technical field [0001] The invention relates to a method for rapidly measuring SO in cement clinker 2 content method. Background technique [0002] SiO in clinker 2 The content has the greatest influence on the saturation ratio of cement clinker, which in turn affects the strength of clinker and finally the strength of cement. SiO in clinker 2 If the content is too low, the clinker saturation ratio will be low, the cement strength will be low, and the factory cement products may be unqualified. On the contrary, if the cement strength is high and the cement surplus strength is high, it will cause waste of resources. Therefore, it is fast, accurate and reliable to detect SiO in cement clinker. 2 It is particularly important to ensure the stable quality of road clinker. SiO in traditional cement clinker 2 The chemical analysis method (GB175-2006) has been used for component analysis for a long time. Although this method has high accuracy and good stability, the operation i...
