The inner wall of the test box is made of 3 stainless steel, which is not decomposed by ultraviolet light, is corrosion-resistant and beautiful, and the outside is made of 3 steel plate spray-painted (the color can be selected by the customer). The inner wall and outer body The channel steel angle iron frame is used in between, which is strong and durable as a whole, and the appearance of the entire laboratory is beautiful and elegant.
According to the provisions of the standard, a row of lamp tubes is designed indoors to meet the needs of two groups of sample solar panels being tested at the same time. The distance between the centers of the lamp tubes is arranged according to the maximum size of the samples. The distance between the center of the lamp tubes and the sample can be Adjustment, completely refer to the provisions of the standard. The ultraviolet lamps and B are divided into groups, and the ultraviolet lamps B and B are staggered and installed separately and controlled in groups. The irradiation amount that meets the requirements at the same time is. ?-, the irradiation amount of 3- is ?-, and the cumulative irradiation amount When the set value is reached, the device automatically shuts down.
A solar panel stand is designed indoors to meet the installation of solar panels of different sizes. The height is based on the sample or customer requirements, and the distance from the lamp can be adjusted to meet different samples and adjust the radiation with different requirements. For illumination, the gantry on which the light tube is installed is a special device that can install light tubes that meet the largest sample size, parallel to the sample. After the sample is installed, the two ends and the upper and lower gaps are filled with special templates so that the surface and back of the sample are in different temperature and humidity environments. The surface is exposed to light, temperature, humidity, and rain, while the back is in natural flowing air, creating the most realistic simulation. environment of. A fan is used on the back of the sample to move the air and keep it consistent with the environment.
The connecting wires at both ends of the lamp are specially designed to ensure that they will not be corroded by water and cause a short circuit under high indoor humidity or spray conditions. The installation design of the lamp is simple and convenient, and customers can easily replace the lamp.
Install a set of ultraviolet radiation measurement and control instruments to detect indoor ultraviolet irradiance and cumulative irradiation to meet the standards. The radiation measurement and control instrument is a product produced by Beijing Normal University and has passed national testing. More realistic simulation of environmental testing.
A special air-conditioning device is installed indoors, with air heating and water heating heaters arranged to meet the required temperature and humidity in the test room. The circulating air system keeps the indoor temperature and humidity uniform. Several nozzles were reasonably designed in the gaps between the lamp tubes on the lamp stand to conduct a simulated rain test on the samples. The environment of a sudden heavy rain when the temperature is the highest in summer and the light is the strongest is reproduced. The surface temperature of the sample drops sharply. At the same time, Condensation is generated on the back of the sample and the sample is subjected to the most severe environmental test.
A ventilation device is installed on the top, and the instrument is automatically controlled. When light and condensation alternate, the indoor temperature and humidity can be quickly and uniformly maintained, and ozone gas generated by ultraviolet light is eliminated.
Ensure that the ~ range test spectral irradiance does not exceed . times the standard solar spectrum irradiance, that is, less than ~.
When executing 3, set ~3 irradiation amount.?- and 3~irradiation amount?- respectively. When executing, set ~3 irradiation amount?- and 3~3 irradiation amount?- respectively. After the parameters are input, the instrument automatically completes the test
3. Temperature and humidity control
Cycle
The first-level photochemical reaction is not sensitive to temperature changes. However, the speed of the subsequent secondary reaction is closely related to the temperature change. Generally speaking, as the temperature increases, the reaction rate increases. Therefore, temperature control is very important during the exposure test. What is more important is to match the test temperature used in the accelerated test with the highest temperature encountered by the material in actual applications. The temperature setting in the device can be anywhere from ℃ to ℃, depending on the light level and indoor ambient air temperature. The temperature adjustment of the equipment is completed by using a controller with a microcomputer calculation function to direct a series of systems in the equipment such as air heaters, water heaters, etc.
Moisture circulation
As the temperature increases, the destructive power of moisture on materials will increase dramatically. Therefore, temperature control is the most basic requirement during wet exposure. Furthermore, to produce an accelerated effect, it is necessary to maintain a high temperature environment during the moist exposure process. The condensation process temperature setting in the equipment can be any point from ℃ to ℃.

During the cycle test, there is a test section that is a dark condensation process, which requires higher temperature saturated water vapor to be generated in the box. When the water vapor encounters a relatively cold When the sample surface is exposed to water, dew will condense on the sample surface.
