[0148] Example Evaluation of the quality stability of calcium carbonate

[0149] Calcium carbonate 1-5 is provided, calcium carbonate is based on calcium carbonate 1. use Figure 1-2 The method and device for evaluating the quality stability of calcium carbonate are used to evaluate the quality stability of calcium carbonate 2-5 relative to the reference calcium carbonate.

[0150] During the thermogravimetric analysis, the atmosphere is air, the carrier gas flow rate is 100mL / min, the heating rate is 10K / min, and the maximum temperature is raised to 1273K, and the DTG curve of calcium carbonate 1-5 is obtained, as image 3 shown. The standard root mean square error (N is 3500) between the calculated DTG curve of calcium carbonate 2-5 and the standard calcium carbonate DTG curve in the pyrolysis temperature range of 850K-1150K is shown in Table 1.

[0151] Using calcium carbonate 1-5 as an additive, prepare tobacco sheets 1-5 according to the same conventional method, and...

Abstract

The invention belongs to the field of additive detection and in particular relates to a method for evaluating quality stability of calcium carbonate. The method comprises the following steps: acquiring a DTG (Differential Thermal Gravity) curve of standard calcium carbonate; acquiring a DTG curve of calcium carbonate to be tested; calculating a standard root-mean-square error of the two DTG curveswithin a pyrolysis temperature range of a calcium carbonate compound; if the standard root-mean-square error does not exceed a threshold, judging that the calcium carbonate to be tested is stable inquality relative to standard calcium carbonate, or else, judging that the calcium carbonate to be tested is not stable in quality relative to the standard calcium carbonate. On the basis, the invention further relates to a device for evaluating quality stability of calcium carbonate. By adopting the method provided by the invention, the quality stability of calcium carbonate can be accurately andcomprehensively reflected, and furthermore, long-term stability of quality and style of regenerated tobacco products can be effectively controlled.

Description

technical field [0001] The invention belongs to the field of additive detection, and in particular relates to a method for evaluating the quality stability of calcium carbonate, and also relates to a device for evaluating the quality stability of calcium carbonate. Background technique [0002] Calcium carbonate is an important additive in the process of reconstituted tobacco leaves by papermaking method, and also an important component in reconstituted tobacco leaves by papermaking method. When smoking cigarettes, calcium carbonate is burned together with reconstituted tobacco leaves. The researchers found that different qualities of calcium carbonate involved in combustion had different effects on the sensory quality of reconstituted tobacco leaves. Therefore, the quality stability of calcium carbonate affects the stability of the quality and style of reconstituted tobacco leaves. In order to control the quality stability of the produced reconstituted tobacco leaves, it i...
