The test process comprises the following steps: 1. Adhering a test surface of the sample on a sample support by using a waterproof adhesive tape; 2. performing tests according to specified technical requirements (water temperature, sample time, water conductivity and the like), for example, adjusting the water temperature in a water tank to 60 ℃, and testing the test time to 240 hours; 3. and after the specified test time is reached, taking out the sample to perform the moisture resistance evaluation of the coating according to the enterprise standard requirements.

In the test process, due to the lack of a special fixture for fixing the sample, the adhesive tape is easy to lose the viscosity in a high-temperature and high-humidity state for a long time, so that the sample is displaced or falls into water, the specific failure time of the moisture resistance test of the sample coating cannot be accurately known, the test result can be influenced by the fact that the actual condition of the field cannot be completely simulated, and the test time and resources are wasted; in addition, the test state cannot be observed by detaching the test piece at any time in the test process, the test piece can be detached only after the set test time is reached, and some test pieces can fail in 240 hours, so that the specific failure time of the moisture resistance test of the coating of the test piece cannot be accurately known, and the test result is influenced. In order to make the test more scientific and more convenient, a set of fixing tool for the coating moisture resistance test is indispensable.
