Abstract

The invention discloses a method for rapidly calculating the self-accelerated decomposition temperature of a substance and application of the method, and belongs to the technical field of research on rapid determination of thermal hazard characteristics of the substance. The technical problems of high risk and the like caused by long self-accelerated decomposition temperature test period and large test sample quantity are solved. The method comprises the following steps of: testing decomposition reaction and exothermic characteristics of a substance in air to obtain a thermal flow velocity curve of the substance; observing whether an exothermic peak appears in a thermal flow velocity curve within the range of room temperature to 300 DEG C, if the exothermic peak appears, calculating the thermal stability parameter of the substance, and calculating the thermodynamic parameter of the substance; the relation that the temperature changes along with a reaction heat release rate according to the thermodynamic parameter is formulated, and the relation that the temperature changes along with the heat removal flow rate of a cooling system according to a packaging parameter corresponding to the substance is formulated. and finally, when the qe is tangent to the qr, the environment temperature corresponding to the qe is the SADT of the substance. According to the method, the self-accelerated decomposition temperature of the substance can be quickly and effectively obtained, and the safety is high.

Description

technical field [0001] The invention relates to the technical field of researching and quickly determining the thermal hazard characteristics of a substance, in particular to a method for quickly calculating the self-accelerating decomposition temperature (SADT) of a substance and its application. Background technique [0002] At present, the self-accelerating decomposition temperature of substances is widely used in the world to evaluate the thermal stability of substances. Self-accelerating decomposition temperature (SADT) is defined as the self-accelerating decomposition of substances in actual packaging within 7 days Minimum ambient temperature. The self-accelerating decomposition temperature is not only related to the structure of the substance itself, but also related to the concentration and packaging form of the actual packaged product. Therefore, the substance needs to be assessed for risk before storage and transportation to formulate corresponding safety control c...
