In the accelerated simulation test, the non-stick life is determined after each cycle is completed. The endpoint can be determined by one of the following phenomena:
(1) the non-stick property is reduced:
the non-stick grade of the fried eggs is continuously classified as grade III for two cycles;
(2) appearance failure:
scratching, exposing and fouling;
the number of simulated test cycles at the end of the test was recorded as the non-stick life of the product, with more cycles indicating a longer non-stick life of the coating, and the test results are shown in table 1.
2. According to the evaluation test of the non-sticky dishes of the QJ/WS210-2022 pot, in the process, a shovel is simulated to be normally used for testing, and finally, the condition of the coating in the pot is observed.
