The equipment is suitable for artificial accelerated testing of plastics, coatings, rubber materials, solar modules, and electronic products in simulated sunlight environments; Used to evaluate changes in materials such as fading, color changes, gloss, cracks, etc., in order to provide a basis for improving material formulations and enhancing product performance.
2. The sunlight UV simulation provided by the equipment has the characteristics of low maintenance cost, easy use, automatic control operation, high degree of automation in the test cycle, good lighting stability, and high reproducibility of test results.
Heating system:
1. Adopting U-shaped titanium alloy high-speed heating electric heating tube
2. The temperature control output power is calculated by a microcomputer to achieve high-precision and high-efficiency electricity efficiency
3. Anti overheating function with heating system
Blackboard temperature control:
1. Using black aluminum plate to connect temperature sensor
2. Using a blackboard temperature meter to control heating, the temperature is more stable
Circuit control system:
1. Intelligent ZN4-14S series Korean Autonex temperature controller with control accuracy of ± 0.1 ℃
2. Thin film KEY BOARD
3. Equipped with power-off memory function, it can continue the remaining test process when restored to power
4. The temperature control adopts P.I.D+S.S.R, and the system coordinates control with the same channel, which can improve the stability and service life of control components and interfaces
5. Touch sensitive settings, digital and direct display
6. Equipped with P.I.D automatic calculation function, it can reduce the inconvenience caused by manual setting
7. Lighting, condensation, and spraying can be independently controlled or alternately controlled in a cyclic manner
8. The independent control time for lighting and condensation, as well as the alternating cycle control time, can be set arbitrarily within one thousand hours
9. In operation or setting, if an error occurs, a warning signal will be provided.
10. Non Lipu rectifier and starter (ensuring that the UV light can be turned on every time the machine is turned on)

1. The fixed device for the test sample is placed on the test rack. When facing the fluorescent lamp, if the sample rack is not filled with the sample, a blackboard is needed to fill the sample rack and keep the inner wall of the test box closed.
2. Test temperature: When exposed to light, three temperatures of 50 ℃, 60 ℃, and 70 ℃ can be used, with 60 ℃ being the preferred temperature; The temperature during the condensation stage is 50 ℃, with a temperature tolerance uniformity of ± 2.
3. The condensation cycle for each illumination can be selected from two cycles: 4H illumination and 4H condensation, or 8H illumination and 4H condensation.
4. After 400-450H of * lighting, each row of lamps needs to be replaced with a fluorescent lamp, and other lamps should be compensated for the losses caused by lamp aging according to the lamp cycle and replacement method. This operating mode ensures that the service life of each lamp tube is between 1600-2000H.
5. When replacing the lamp tube, the water tray should be wiped dry and cleaned to avoid the formation of scale.
