Usb Uv Accelerated Weathering Tester Equipment Ss 304

UV weather tester, USB Accelerated Weathering Tester Equipment

I. Overview

This product adopts the fluorescent UV lamp which best simulates the UV spectrum of sunlight, and combines the devices such as temperature control and moisture supply to simulate the sunlight which causes discoloration, brightness, strength drop, cracking, flaking, chalking and oxidation of the material. UV segment) factors such as high temperature, high humidity, condensation, dark rain cycle, etc., 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 for material resistance. The evaluation of climate performance, the equipment has the best sunshine UV simulation, low maintenance cost, easy to use, automatic control of equipment operation, high degree of automation of test cycle, good light stability and high recurrence rate of test results.

Ⅵ. Temperature control

UV:

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℃ and 60℃.

Ⅶ.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:

1) The temperature of the blackboard is controlled by a color touch screen program controller or a digital button temperature controller. The output power is calculated by the microcomputer, PID self-tuning, and the standard PT100 blackboard temperature sensor is used for monitoring.

2) 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.
