Analyze the correct operation process steps of UV aging test box

The UV Accelerated Weathering Tester uses a fluorescent UV lamp as the light source to conduct accelerated weathering tests on materials by simulating UV radiation and condensation in natural sunlight to obtain the results of material weatherability. It can simulate the environmental conditions of ultraviolet, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in the natural climate. By reproducing these conditions, it is combined into a cycle, and it is automatically executed to complete the number of cycles. But in the whole testing process, we have to master the correct operation process steps of UV Accelerated Weathering Tester; but do you know what the correct operation process steps are? Next, I will share with you the correct operation process of UV Accelerated Weathering Tester. step:

The process steps are divided into: first, prepare the UV Accelerated Weathering Tester before it is turned on correctly, and then put the test samples on the sample rack in order before turning on the power supply, and then use the black metal plate at the place where it is not full. So fill and close the box doors on both sides; when it is connected to the water source, the water should be in the preparatory stage. After the power is turned on, the liquid level switch will automatically open and close the solenoid valve to add the water to the set water level, and It is to ensure that it is humidified to meet the needs of condensation; before the power is turned on, first set the total test time, illumination time and condensation time in advance, and after the power is turned on, the test equipment runs according to the set time. The test value is commanded to run; during its operation, it is necessary to change its related data and turn off the main power to restart; the ultraviolet light energy output in the box will gradually decrease with time, in order to reduce the reduction of light energy due to the decrease of light energy. If the influence of the test is caused, in the test, one of the eight lamps should be selected to replace an old lamp with a new lamp every 1/4 of the life of the fluorescent lamp.

PS: UV Accelerated Weathering Tester conducts a uniform and smooth test on the test sample, and needs to leave a certain back path in the test state. In order for the test sample to be stressed more uniformly during its test cycle, the most assured preparation is required before the test.

The above is all the content of the correct operation process steps of UV Accelerated Weathering Tester to share with you.
