| 摘 要： | 对几种物质化学反应过程中的温度变化进行定性实验,选出其中效果较好的几组物质,进行差热分析(DTA),定量测出这些物质的化学反应温度。由焓变涂料效果测试实验得出,碳酸钙、碳与氧化锌、碳与碳酸钠涂料是3种吸热涂料,其中碳酸钙涂料吸热效果最好;碳酸钙与镁、氧化铁与镁、氧化铁与锌涂料是3种放热涂料,其中前两者效果更好。

| Abstract: | Qualitative experiments of different chemical reactions were carried out with Paperless Recorder to test the temperature change.Differential thermal analysis experiments have been done to quantitatively test the chemical reaction temperature of the subtances which reactive effect were relatively better.The results of the effect test for enthalpy-changing coatings were: of the three endothermic coatings,which wereCalcium carbonate,Carbon and Zinc oxide,Carbon and Sodium carbonate,the first group was the best... |
