Description
Technical Field
The invention belongs to the field of analysis and detection of a gypsum phase, and particularly relates to an analysis and detection instrument for a gypsum phase composition and a use method thereof.
Background
The analysis and detection of the gypsum phase generally refers to the analysis and detection of three phases of building gypsum, and the phase composition of the building gypsum powder, especially the three-phase composition (anhydrous gypsum III, semi-hydrated gypsum and dihydrate gypsum) plays an important role in the selection of production process parameters and product quality control of gypsum products such as gypsum boards, gypsum blocks and the like, so that the rapid and accurate phase analysis of the building gypsum powder is concerned by gypsum product enterprises in large-scale continuous production. At present, all domestic gypsum product production enterprises use a gravimetric method to perform a gypsum three-phase test, namely, the gypsum three-phase test is calculated by utilizing the weight difference generated by dehydrating dihydrate gypsum (DH) and hemihydrate gypsum (HH) at different temperatures.
The soluble Anhydrite (AIII) in the building gypsum is hygroscopic and absorbs water in the air to be converted into hemihydrate gypsum (HH), so that the soluble Anhydrite (AIII) and the attached water are not present in the sample at the same time. The soluble Anhydrite (AIII) can be hydrated into hemihydrate gypsum in a 95% aqueous ethanol solution, and the hemihydrate gypsum (HH) cannot be hydrated into dihydrate gypsum (DH) under the same conditions, so that the content thereof can be calculated by measuring the increase in the hydration of the soluble Anhydrite (AIII) in a 95% aqueous ethanol solution.
The hemihydrate gypsum (HH) and the soluble anhydrous gypsum (AIII) can be completely hydrated into dihydrate gypsum (DH) in pure water, the hydration increment of the building gypsum in the pure water is measured, namely the total amount of the dihydrate gypsum (DH) formed by the hemihydrate gypsum (HH) and the soluble anhydrous gypsum (AIII) is measured, and the content of the soluble anhydrous gypsum (AIII) which is measured is subtracted (when the anhydrous gypsum (AIII) phase is not contained, the mass loss of the baked attached water is added), so that the content of the hemihydrate gypsum (HH) can be calculated.
The content of the remaining dihydrate gypsum (DH) can be calculated by heating the building gypsum to 200 ℃ or higher, dehydrating the dihydrate gypsum (DH) to obtain the soluble anhydrous gypsum (AIII) in which the total amount of dehydration is the sum of the amounts of dehydration of the dihydrate gypsum (DH), the hemihydrate gypsum (HH) and the adhering water, and subtracting the amounts of dehydration of the hemihydrate gypsum (HH) and the adhering water.
The existing gypsum phase composition analysis and detection method generally adopts the GBT/36141-2018 building gypsum phase composition analysis method. The existing gypsum three-phase method adopts a drying box, a balance and related experimental apparatuses for analysis and inspection, each step needs manual weighing analysis, and the whole experimental process needs more than ten hours. The gypsum three-phase value is the most basic index for determining the quality of gypsum, and the detection result is difficult to effectively guide the production of gypsum enterprises through overlong experimental determination.
Problems existing in the prior art: the process of testing the gypsum three-phase composition depends on manual work, the labor intensity of experimenters is increased, dried samples need to be weighed repeatedly, the operation error is easy to be large, the detection time is as long as more than ten hours, and the time consumption is long.
