Single-tube xenon lamp aging test chamber can simulate the natural environment

Natural sunlight and moisture damage materials, causing incalculable economic losses every year. The damage caused mainly includes fading, yellowing, discoloration, strength reduction, embrittlement, oxidation, brightness reduction, cracking, blurring and powdering, etc. There is a risk of photodamage effects on products and materials exposed to sunlight, either directly or through glass windows. Materials that are exposed to fluorescent, halogen or other luminous lights for long periods of time are also affected by photodegradation.
The xenon lamp climate resistance test chamber uses a simulated xenon arc lamp to reproduce the destructive light waves that exist in different environments. This equipment can provide corresponding environmental simulation and accelerated testing for scientific research, product development and quality control.
The xenon lamp climate resistance test chamber can be used for tests such as selecting new materials, improving existing materials, or evaluating changes in durability after changes in material composition. The equipment can well simulate the changes caused by exposure of materials to sunlight under different environmental conditions.
2. Structural design
The equipment is mainly divided into the main part, heating, humidification, dehumidification part, display control part, air conditioning part, safety protection measures part and other accessory parts
This equipment is unique The sample rack tray is very convenient to use. The tray is tilted to the horizontal direction and can be used to place flat specimens or three-dimensional samples of different shapes and sizes, such as parts, components, bottles and test tubes. This kind of tray can also be used for testing materials that will flow in high temperature environments, materials exposed in bacterial petri dishes, and materials that have a waterproofing effect on roofs

4. Circuit control system
This xenon lamp climate test chamber has a variety of cycle programs, blackboard temperature and test chamber air temperature and humidity to choose from, and is used to program to simulate different usage environments. . The exposure function and temperature are controlled by a microcomputer automatic calculation and D self-tuning function, a membrane button type intelligent temperature controller, which is simple and fast to operate. The time can be divided into total time, lighting time, spraying and spraying stop time to be set separately. After the setting is completed, the equipment will automatically run according to the entered program. The light irradiance display will show the current light irradiance intensity at any time. If an abnormality occurs during the test or after the test is completed, the device will immediately sound an alarm and automatically terminate the test.
