UV cycle

The first-order photochemical reaction is not sensitive to temperature changes. However, the speed of the subsequent secondary reaction is closely related to temperature changes. Generally speaking, as the temperature increases, the reaction rate will accelerate. Therefore, temperature control is crucial during UV exposure testing, and it is even more important to match the test temperature used for accelerated testing with the highest temperature encountered by the material in practical applications. The temperature setting of UV in the device can be any point from 50 ℃ to 80 ℃, depending on the level of illumination and indoor ambient temperature. The temperature regulation of the equipment is controlled by a controller with microcomputer calculation function to command a series of systems inside the equipment, such as air heaters, water heaters, etc.

Moisture cycle

As the temperature increases, the destructive power of moisture on materials will sharply increase. Therefore, temperature control is the most basic requirement during wet exposure. Furthermore, to achieve an acceleration effect, it is necessary to maintain a high temperature environment during the wet exposure process. The temperature setting for the condensation process in the device can be any point from 40 ℃ to 60 ℃.

2. Temperature control and lighting are completely independent systems;

3. The temperature control output power is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency;

4. Equipped with anti overheating function of heating system;

The temperature of the black aluminum plate is controlled by a Japanese made RKC series temperature controller for heating, and the output power is calculated by a microcomputer with PID self-tuning. The monitoring adopts standard Pt-100 blackboard temperature sensor;

The temperature of the sink is also controlled by a Japanese made RKC series temperature controller for heating. The sink is located at the bottom of the box and is equipped with an electric water heater. During the cyclic testing process, there is a testing section called the dark condensation process, which requires the box to generate saturated water vapor at a relatively high temperature. When the water vapor encounters a relatively cold surface of the sample, it will condense on the surface of the sample.
