UV Test Chamber Application
UV spectra is a part of sunlight spectra, causing damage to test pieces. All the specimens needed to be under UV light radiation can be tested in the UV test chamber. For example, plastics, rubber, coatings and etc. in automotive industry, aerospace, building materials. UV testing chambers, as a type of uv accelerated weathering tester, are also widely used in scientific laboratory conducting research on material aging and photochemistry.
Configuration of UV Test Chamber
①Control system
In order to find the UV lamp failure or light source decay in the first time, UV test chamber is equipped with four current display devices on control system to remind the experimentered in real time.
②Radiometer
The radiometer is equipped with probes in a specific wavelength range 290-400 nm.
③Black Panel
Black panel temperature equals the temperature transmitted by hot air (working room) + The temperature produced by irradiation by a light source.
④Heating system
There are two kinds of heating tubes at the bottom of the workroom, U-shaped heating tube to heat the workroom, circular heating pipe to heat the water, and a fan under the middle air duct to blow the heating moisture upward.
⑤Humidity system
The heating tube is immersed in water, which is heated to form steam to humidify the workroom.
⑦Spray Nozzle
Water spray pipe is equipped with ten nozzles, the diameter of the nozzle is 0.5mm, the settlement is 0.8 ~ 1.0mm / 80cm2 / H, and the flow rate is 0.3L / min, which simulates outdoor moisture damage to the material.
How to Choose Proper UV Test Chamber？
• Specify what kind type of uv aging test to be performed, based on your sample size and quantity, and the required test standards and specifications.
• Different types of UV lamps are suitable for different test purpose. UV test chamber usually uses fluorescent ultraviolet lamp as light source such as UVA-340, UVB-313 and so on.
• If you need to simulate the combined environment conditions such as uv light damage with rain corrosion, the uv light test chamber with spray function, you can set spray time, spray cycles.
• UV test chambers from professional environmental chamber manufacturers with crediable after-sales service can ensure attain real-time and professional help.
LIB Industry UV Test Chamber Working Principle
The working principle of UV test chamber is to use fluorescent uv lamp as the light source, through the simulation of ultraviolet radiation in the natural sunlight, the sample in the workroom will be exposed to the ultraviolet radiation, to accelerate the aging process of the material. By testing and analyzing the properties of the samples before and after the test, the performance of weatherability, durability and color change of the materials can be evaluated. The UV aging test chamber can control the temperature, humidity, light intensity and other parameters to ensure the accuracy and reliability of the test.
