Uses:


This product adopts fluorescent UV lamp which can best simulate the UV spectrum of sunlight, and combines temperature control, moisture supply and other devices to simulate the discoloration, brightness and strength degradation of materials; cracking, spalling, chalking, oxidation and other damage. Sunlight (UV segment) high temperature, high humidity, condensation, dark cycle and other factors, and through the synergy between ultraviolet light and moisture, the material's single light resistance or single moisture resistance is weakened or invalid, so it is widely used in materials. The evaluation of weather resistance performance, the equipment has the best sunshine UV simulation, low maintenance cost and easy to use, the equipment adopts the automatic operation test cycle of the program controller, high automation degree, good light stability and high test result reproducibility.

Ultraviolet light:


The first-order optical reaction is not sensitive to temperature changes, however, the rate of subsequent secondary reactions is closely related to temperature changes. Generally speaking, as the temperature increases, the reaction speed will increase. Therefore, during the UV exposure test, temperature control is very important. More importantly, the test temperature and materials used in the accelerated test are in practical applications. The highest temperature encountered is matched. The temperature of the UV process in the equipment is set to any point between 50 ° C and 70 ° C depending on the illuminance level and the indoor ambient temperature. The temperature adjustment of the device is performed by a controller with a microcomputer calculation function to direct a series of systems such as an air heater and a water heater in the device.


Moisture:


As the temperature increases, the destructive power of the material on the moisture increases dramatically. Therefore, temperature control is the most basic requirement in the process of moisture. Furthermore, the acceleration effect is required to maintain a high temperature environment during the humid process. Therefore, the temperature in the condensation process is set to any point between 40 ° C and 60 ° C.


Heating system:


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

2, temperature control and lighting completely independent system

3. The temperature control output power is calculated by the microcomputer to achieve high precision and high efficiency.

4, the heating system has anti-overheating function:

5. Blackboard temperature adopts color touch screen program controller, output power is calculated by microcomputer, PID self-tuning, monitoring adopts standard PT100 blackboard temperature sensor.

6. The temperature of the water tank is controlled by a color touch screen program from a Korean temperature controller. The water tank is located in the lower part of the cabinet and has a built-in electric water heater. During the test, one test section is a dark condensation process that requires saturated water vapor at a higher temperature in the tank. When the water vapor encounters a relatively cold surface, condensation will form on the surface of the sample.


Sprinkler System:


1. Spray uniformity adjustment. Use the manual control function of the controller. Observe the spray condition in the open state.

2 Sprinkler status monitoring: The machine is equipped with a sprinkler. The sprinkler simulates temperature drastic changes and rain erosion during rain. There are several nozzles. Spray evenly. When to spray. How long is the spray. All are freely set by the customer.
