How to choose the refrigeration mode of xenon-lamp weathering test chamber?
Xenon-lamp weathering test chamber simulates the harm caused by sunlight, rain and dew, uses xenon lamp to simulate direct sunlight exposure to photoaging products, and places the test material in a cycle of alternating light and moisture at a certain temperature for testing, uses a few days or weeks to detect the harm that may occur in outdoor months or even years. Finally we can know whether the product is weather-resistant or not. It is mainly suitable for coating, building materials, textiles, furniture leather and other industries.
（Xenon-lamp Weathering Test Chamber of Lab Companion）
There are two kinds of refrigeration methods of xenon lamp weather test chamber: air cooling and water cooling. How to choose the refrigeration method of Xenon lamp weather test chamber? As the saying goes, knows oneself and the other side is undefeated in many battles. Let's start with the advantages and disadvantages of air cooling and water cooling. The following is a comparison chart organized by editor for everyone:
|
|
Advantages |
Disadvantages |
|
air cooling |
The tube of the air-cooled xenon lamp is installed horizontally above the inner box of the equipment, and the sample rack is installed in the middle of the inner box. The distance between the sample rack and the lamp can be adjusted according to the size of the sample. The structure is simple and the test space is large. |
The distance between the samples in the inner box and the lamp tube is not fixed, and the radiation of the samples placed at the corners is weak, so it is necessary to suspend the test and adjust the sample placement. |
|
water cooling |
The tube of the water-cooled xenon lamp is mounted vertically in the middle of the device, and the turntable containing the sample rotates around the tube. The distance between each sample and the lamp is equal, which can avoid the defect of insufficient radiation of the samples at the corners, and ensure that each sample gets the same irradiation intensity, and has good comparability. |
The volume of rotary disk installation equipment is relatively large, and the need to configure cold water equipment and pure water system, so the cost has increased. |
Through the above comparison, it can be seen that the refrigeration method of selecting xenon lamp weathering test chamber is mainly considered whether the test machine sample is regular. If the sample is regular and the size is relatively small, it is recommended to use water-cooled type, if the sample is irregular and the size is relatively large, it is not easy to sample, it is recommended to use air-cooled type.
