Background
The solar radiation test is a manual simulated environmental test that simulates the effects of exposure of a product to solar radiation during use on the ground or in a lower atmosphere or during storage without shading.
The influence of solar radiation on the product is mainly generated by a heating effect and a photochemical effect; the heating effect is mainly generated by the infrared spectrum part in solar radiation energy, and mainly causes short-time high temperature and local overheating of products, so that some components sensitive to temperature fail, mechanical damage of structural materials, overheating damage of insulating materials and the like; the photochemical effect is mainly generated by ultraviolet spectrum part in solar radiation energy, and light energy provided by the ultraviolet spectrum is enough to excite organic material molecules to break, degrade or interact bonds of the organic material molecules, so that the material is aged and deteriorated.
When solar radiation is combined with climatic factors such as temperature, humidity and the like, the damage of the solar radiation is more obvious, and the most easily found damage is surface damage such as deformation, color change, gloss loss, chalking, cracking and the like; meanwhile, the inherent mechanical property and electrical property of the material are reduced, so that the use value of the material is reduced and even the material is scrapped.
Generally, the heating effect mostly adopts a circulation mode: 8 hours of continuous irradiation, 16 hours of darkness, 24 hours being a cycle. Continuous irradiation is mostly adopted for the photochemical effect, and the photochemical effect test is used for researching the influence of long-term exposure to sunlight on a test sample.
In the existing technical mode, the following inspection steps are mainly adopted for main technical parameters:
(I) testing the distribution of radiant intensity and spectral energy
1. Arranging the sensors at specified positions to make the sensing surface of the sensors perpendicular to the incident direction of the light source
2. Starting a light source, measuring the radiation intensity of each point in sequence after the light source is stable, and continuously measuring each point for three times at a time interval of 1 min;
(II) checking temperature deviation, temperature fluctuation degree and temperature indication error
1. Selecting nominal value of inspection temperature
In the adjustable range of test equipment, a representative temperature nominal value specified in GB/T2423.24 standard is generally selected, and the temperature is as follows: 25 ℃, high temperature: at 40 ℃ and 55 ℃; other temperature nominal values can be selected according to the requirements of tests and inspection;
2. placing the sensor at a specified position, and shielding the sensor to prevent the radiant heat effect, wherein the light source is not directly irradiated on the sensor;
3. the light source is activated to achieve a specified radiation intensity for the apparatus
4. Adjusting the temperature controller of the test apparatus to the desired nominal temperature
5. Cooling or heating the test equipment, stabilizing for 30min after entering a temperature control state, starting to record the temperature of each measurement point and the equipment indication temperature, recording once every 1min, and recording for 30 times in 30 min;
(III) checking the average rate of change of temperature every 5min
1. Placing the sensor at a specified position, and starting the light source to enable the test equipment to reach specified radiation intensity;
2. the temperature of the apparatus is tested according to test methods A, B and C in GB/T2423.24 or other temperature change programs, and the temperature of the measurement point is recorded every 1min during the temperature rise.
The solar radiation test chamber (salt spray test chamber) on the market at present has the following major disadvantages: 1. environmental conditions of pure solar radiation; 2. because components used in the solar radiation test box, such as a sensor, a xenon lamp and the like, cannot be in a temperature and humidity environment for a long time, the components are directly combined, corresponding tests are required to be carried out on the components, and the solar radiation test box has one of the great defects; 3. comprehensive tests of rain and solar radiation cannot be simulated; 4. comprehensive tests of various environments cannot be performed by the program.
