Description

technical field [0001] The invention relates to the technical field of thermal stability detection, in particular to a rapid thermal stability detector and a detection method. Background technique [0002] With the continuous development of energy problems, solar thermal utilization technology has achieved unprecedented development in recent years. As a key component in the field of solar thermal utilization, the solar collector's stability and life determine the performance of the entire solar thermal system; at the same time, in order to improve the system's light-to-heat conversion efficiency, the most direct and effective way is to improve the heat-absorbing coating working temperature. In view of the above two reasons, the current research focus on heat-absorbing coatings at home and abroad is mainly focused on how to improve the thermal stability of heat-absorbing coatings for solar collectors, and to obtain heat-absorbing coatings that can withstand higher temperatur...

Problems solved by technology

This method has the shortcomings of long inspection time and low efficiency, and because the inspection time is too long, a large number of strips cannot be carried out to the next step, resulting in a backlog; the second is to take out the small test pieces that accompany the furnace as a representative of the quality of the furnace. The sample is heated to a certain temperature through a high-temperature furnace for inspection

This method has the defect that the test results are inconsistent with the actual results, because the planar shape of the test piece is slightly different from the strip wing plate, and it is difficult to ensure that the coating quality is completely consistent with the strip coating during the coating process. Once the test is wrong, It is possible that the entire furnace strip needs to be reworked, which will virtually increase the production cost and increase the risk
