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 enthalpychanging coatings were: of the three endothermic coatings, which wereCalcium carbonate, Carbon and Zinc oxide, Carbon and Sodium carbonate, the first group was the best; of the three exothermic coatings, which were Calcium carbonate and Magnesium, Iron oxide and Magnesium, Iron oxide and Zinc, the first two groups were better.
