During the test, some dirt will be generated after the sample is heated and will adhere to the surface of the copper sheet of the copper calorimeter sensor. As the number of tests increases, the dirt adhering to the surface of the copper sheet of the copper calorimeter sensor will also increase, which will affect the temperature acquisition and cause the test results to deviate. At this time, the surface of the copper sheet of the copper calorimeter sensor must be treated.

[0034] When processing the surface of the copper sheet of the copper calorimeter sensor, the operator first uses a scraper or similar tool to remove the dirt adhering to the surface of the copper sheet. Then, sandpaper is used to polish it until the dirt is completely cleaned. Next, compressed air is used to blow away the dust to thoroughly clean the surface of the copper sheet. Finally, a special mold is placed on the surface of the copper calorimeter, exposing only the surface of the copper sheet. A matte black paint with high temperature resistance (above 300℃) and no gloss and an absorption rate greater than 0.9 is applied to the copper sheet. The paint is then dried and cured. The process of spraying and drying the paint is repeated three times to achieve uniform thickness and a smooth surface.
