Temperature control< br/> Cycle
The first-order photochemical reaction is not sensitive to temperature changes. However, the speed of the subsequent secondary reaction is closely related to the temperature change. Generally speaking, the reaction speed will increase as the temperature increases. Therefore, temperature control is very important during the exposure test. What is more important is to match the test temperature used in the accelerated test with the temperature encountered by the material in actual applications. The temperature setting in the device can be any point from ℃ to ℃ depending on the light level and indoor ambient air temperature. The temperature adjustment of the equipment is controlled by a controller with microcomputer calculation function.
Heating system
Using high-speed titanium alloy heating electric heating tube
Temperature control and lighting are completely independent systems
Temperature control output power is calculated by microcomputer to achieve high precision and efficiency Electricity benefits
It has the anti-overtemperature function of the heating system
During the cycle test, there is a test section which is the dark condensation process, which requires the box to be able to generate higher temperature saturated water vapor. When the water vapor encounters When reaching a relatively cold sample surface, dew will condense on the sample surface.

4. Equipment features
The damage caused by natural sunlight to materials causes inestimable economic losses every year. The mercury lamp aging test chamber can reproduce the damage caused by sunlight. The device performs the test by exposing the material to be tested to a controlled alternating cycle of sunlight and darkness while increasing the temperature. The equipment uses a high-pressure mercury lamp to simulate sunlight.
It only takes a few days or weeks for the mercury lamp aging test equipment to reproduce the damage that would take months or years outdoors. The damage caused mainly includes fading, discoloration, decrease in brightness, powdering, cracking, blurring, embrittlement, decrease in strength and oxidation. The test data provided by the equipment is extremely helpful in the selection of new materials, improvements to existing materials, or evaluation of compositional changes that affect product durability. Equipment can do an excellent job of predicting the changes a product will encounter outdoors.
