Abstract

Equipment service environment often has a certain corrosive, accelerate equipment corrosion, affect the integrity of equipment. In order to accurately monitor the micro-environment corrosion strength of the equipment, the multi-channel quartz crystal microbalance calibration test and the crystal vibration sensor temperature supplement test were carried out to realize the frequency-quality signal conversion of the quartz crystal vibration sensor and improve the accuracy of data acquisition of the device. Using a multi-channel quartz crystal microbalance, For an equipment micro-environment under the hot and humid ocean environment, Packaging box under warm and wet acid rain environment, For 30h, respectively, 65h Continuous in situ monitoring, The test data showed that the mass gain of a 30h copper crystal vibration sensor is 0.5 μg, The rate of mass change was 0.017 μg/h, High corrosion strength, Metal materials in this area are prone to corrosion, Key protection is required; The 65h mass temperature increase: 0.022 μg, The rate of mass change was 0.000034 μg/h, Low corrosion strength, The internal metal material is corroded slowly.
