النشرة الإخبارية water-cooled xenon lamp aging test chamber

The water-cooled xenon lamp aging test chamber uses a xenon arc lamp as the light source to simulate and strengthen the weather resistance accelerated aging test equipment to quickly obtain the atmospheric aging test results and evaluate the weather resistance of materials. The weatherability test is an important means of screening formulations to optimize product composition in the process of scientific research and production, and is also an important part of product quality control. Product standards for applied materials such as coatings, plastics, aluminum-plastic panels, and automotive safety glass require weather resistance tests.

The main factors in material aging are sunlight and moisture. The weather resistance test chamber can simulate sunlight, rain and dew, the tested material is put into an alternating program for testingbrought out of light and humidity at a certain temperature and can be reproduced in a few days over several months or even years outdoors or weeks hazards occurring. Accelerated weathering test data can aid in selecting new materials, modifying existing materials, and evaluating how formulation changes affect product durability.

Test Methods for Materials

1. Black Standard Temperature or Black Panel Temperature: When choosing the following two black standard temperatures for exposure tests, refer to: 65 C±3 C Or 100°C±3 'C

Note: The higher value is intended for special tests, it may make the sample more susceptible to thermal degradation and affect the test results. The above temperature is not necessarily the test temperature to be chosen, other temperatures can be chosen if there is an agreement between the parties, but it sollte be stated in the test report that when using water spray, the temperature should be kept constant during the anhydrous period. If the thermometer does not reach the prescribed temperature, the highest temperature reached during the water-free period must be stated in the test report. Although the exposure device works alternately, the black standard thermometer measures continuously. If a black panel thermometer is used, the type of thermometer, its placement and the chosen operating temperature shall be stated in the test report.

2. Relative Humidity: The relative humidity used in the test should be agreed by the relevant parties, therefore the relative humidity measured in the test chamber is not necessarily equal to the relative humidity of the adjacent air surface of the sample.

3. Water Spray Cycle: The water spray cycle used in the test should be agreed by the relevant partiest, but it is best to choose the following water spray cycle: each water spray time: 18 MIN ± 0.5 MIN: two water sprays water-free time between: 102 MIN ± 0.5 MIN

4. Dark cycle: The conditions specified in test methods 1 and 3 are suitable for continuous light tests. A more complex cycle can be chosen for the dark cycle, for example a dark cycle with a higher relative temperature, in which the chamber temperature is increased and condensate forms. The special conditions of the dark cycle test shall be stated in the test report.
