Abstract

The invention provides a method for testing ozone resistance and a device thereof, and the testing method and the device are used for industry. The method for testing the ozone resistance comprises the following steps: 1) firstly placing a test piece; 2) starting a power supply, starting a test and setting a test value; 3) using a blower and an ozone supply device to convey gas into a test box; 4) enabling a temperature and humidity sensor to work; 5) using a PLC (programmable logic controller) to process a feedback vale of the temperature and humidity sensor; 6) enabling an ozone analyzer to work; 7) conveying the gas after completing the analysis into the ozone-resistant test box; 8) using the PLC to process the feedback value of the ozone analyzer; and 9) achieving a preset time value, and finishing the test. The device for testing the ozone resistance comprises the ozone-resistant test box, and the blower, the ozone supply device, a temperature and humidity control device and an ozone concentration monitoring device are connected outside the ozone-resistant test box. The testing method can improve the testing accuracy.

Description

technical field

[0001] The invention relates to an industrial testing method and device, in particular to an ozone resistance testing method and a device thereof. Background technique

[0002] The ozone resistance testing machine provides an environment that can control and adjust the ozone concentration and temperature to measure the ozone resistance performance of the test piece. As the name implies, the ozone resistance testing machine must first simulate an ozone-filled environment, and then put the specimen into the required test. During the test, with the extension of the test time, the ozone concentration in the ozone resistance testing machine test box will change. The index of anti-ozone performance tested under different ozone concentration environments will also be different, which leads to inaccurate test results. Therefore, how to keep the ozone concentration in the test box of the ozone resistance testing machine stable and consistent during the test is an imp...
