On December 5, 2020, the Guangdong Special Equipment Industry Association organized and presided over the development of the original AQSIQ science and technology plan project "Medical Oxygen Chamber Organic Glass Silver Pattern Detection System Development" undertaken by Guangdong Special Equipment Inspection and Research Institute in Foshan City. Research" (Project Number: 2016QK139) Achievement Appraisal Meeting. The appraisal committee believes that the research results of this project have improved the efficiency of plexiglass inspection of medical oxygen chambers and improved the inspection technology of medical oxygen chambers to reach the domestic advanced level.

  Based on the analysis of the mechanism of plexiglass craze generation and expansion, the project established the growth of the plexiglass craze damage density within a certain stress range through experimental research on the growth model of the plexiglass craze damage density The model lays the foundation for evaluating the safe service life of plexiglass under the silver pattern. The plexiglass silver pattern detection system developed by the project shortens the silver pattern detection time and improves the defect detection rate of plexiglass in the medical oxygen chamber. Published 2 papers and obtained 1 utility model patent.
