UV Aging Test Chamber CNHS-150-UV Coating Ink Paint Light Exposure TestIts core advantage lies in its ability to greatly accelerate the aging process of materials, while providing unparalleled testing efficiency and repeatability. It simulates and intensifies the main destructive effects of outdoor sunlight, moisture, and dew through precise control of ultraviolet light, condensation, and temperature cycles. This allows for the precise reproduction of months, even years of natural aging in just a few weeks or days, significantly shortening the product development and improvement cycle. It also enables stable, comparable test data to be obtained under laboratory conditions, completely overcoming the limitations of outdoor testing due to geographical and seasonal climate constraints.

Secondly, this test plays a crucial role in quality control and performance optimization. By precisely replicating issues like fading, loss of luster, and powdering caused by light exposure, as well as bubbling, cracking, and peeling caused by moisture, it effectively filters formulations and distinguishes the quality of raw materials. This provides reliable data support for developing more durable and stable new products, directly enhancing product market competitiveness and preventing customer complaints and quality risks due to premature aging of materials.

Temperature Control:

UV: The primary optical reaction is not sensitive to temperature changes, but the rate of the subsequent secondary reaction is closely related to temperature variations. Generally, as the temperature increases, the reaction rate accelerates. Therefore, temperature control is crucial during the UV exposure test, and more importantly, the test temperature used in the accelerated test should match the highest temperature the material encounters in actual application. The temperature setting for the UV process in the equipment is any point between 50℃~70℃, depending on the light intensity level and indoor ambient temperature. The temperature adjustment is controlled by a microcomputer-based controller that commands a series of systems within the equipment, including air heaters and water heaters.

Humidity:

With rising temperatures, the destructive power of moisture on materials increases dramatically. Therefore, temperature control is the most fundamental requirement during the humidification process. To further achieve an accelerated effect, it is necessary to maintain a high-temperature environment during the humidification process. Hence, the temperature setting for the condensation process is at any point between 40℃ to 60℃.

Heating System

1. U-shaped titanium alloy high-speed heating electric tube adopted

2. Temperature Control and Lighting Independent System

3. Temperature control output power is calculated by a microcomputer for high precision and efficiency in energy use.

4. The heating system features over-temperature protection.

1) The blackboard temperature is controlled by a color touch screen programmable controller or a digital key temperature control instrument, with the output power calculated by a microcomputer, featuring PID auto-tuning. Monitoring is performed using a standard PT100 blackboard temperature sensor.

2) The sink temperature is controlled by a color touch screen programmable Korean temperature controller for heating. The sink is located at the bottom of the cabinet and is equipped with an internal electric water heater. During the testing process, there is a test section that involves a dark condensation process, which requires the chamber to generate a higher temperature saturated steam. When the steam comes into contact with the relatively cooler surface of the sample, condensation forms as dew on the surface.
