Ultraviolet weathering aging test chamber

The test is carried out by exposing the material to be tested in the interaction cycle of controlled sunlight and moisture while increasing the temperature. The equipment is used as an ultraviolet fluorescent lamp to simulate the sunlight, and the moisture effect can be simulated by condensation or spraying. It is the test equipment of aviation, automotive, home appliances, and scientific research. UV weathering aging test chamber is suitable for schools, factories, research, and other units. Using fluorescence ultraviolet lamps to simulate the effects of sunlight, the hazard type includes: fading, discoloration, loss of light, sparkling, cracking, peeling, turbid, bubble, brittle, intensity, recession, and oxidation.

6. Temperature control UV:

Ultraviolet weathering aging test tank optical reactions are not sensitive to temperature changes, however, the speed of the secondary reaction is closely related to temperature changes. In general, as the temperature increases, the reaction speed will speed up, and therefore, during the UV expiration test, temperature control is very important. More importantly, it is necessary to use the test temperature and material used by the acceleration test in practical applications. The ZUI high temperature

is matched. The temperature of the UV process in the ultraviolet weathering aging test chamber is set to any point in 50 ° C to 70 ° C, depending on the level of illuminance and the indoor environmental temperature. The temperature adjustment of the device is to direct a series of systems such as air heaters and water heaters in the equipment with a controller with microcomputer calculation.

7. UV weathering aging test box moisture:

With the improvement of temperature, the destructive power of moisture on the material will increase dramatically. Therefore, in a humid transmissive, temperature control is the basic requirements of ZUI. Furthermore, it is necessary to produce a * fruit that requires maintaining a high temperature environment during moisture. Therefore, the temperature of the condensation process is set to any point in 40 ° C to 60 ° C.

During the test, there is a test segment that is a dark condensation process, which requires a saturated water vapor that can produce higher temperatures in the box. When the water vapor encounters a relatively cold model surface, it will condense the dew in the surface surface.
