The operational considerations of accelerated weathering tester
Weather resistance test is an important means of selecting formula and optimizing product composition in the process of scientific research and production. And it is also an important content of the product quality inspection. Many materials, such as coatings, plastics, aluminum sheets, and automotive safety glass are required to do weather resistance test.
The main factors causing material aging are sunlight and moisture. The accelerated weathering tester can simulate the damage caused by sunlight, rain and dew. And the accelerated weathering tester uses xenon lamp to simulate the effect of sunlight irradiation, and it uses condensing moisture gas to simulate rain and dew. The measured material is placed in the cycle program of alternation of light and moisture at a certain temperature to test. Moreover, the damage outdoor after months or even years can be reproduced in a few days or weeks. Therefore, the data of the accelerated weathering tester can help people to select new materials and modify existing materials.
Accelerated weathering tester has become a common choice in the field of light and weather resistance test, which provides sufficient technical reference and practice for related industries. It can screen formula, optimize product composition and inspect the product quality, which is of great significance. However, the operation of the accelerated weathering tester is a bit complicated. Thus, here is a description of the use and operation of the accelerated weathering tester.
Accelerated weathering tester is suitable for artificial aging test of plastic rubber, paint coating, aluminum plastic board, automobile safety glass, textile printing and dyeing and other products in light, rain, high temperature, high humidity, condensation and dark environment. That is to evaluate the weatherability of plastic rubber, paint coating, aluminum plastic board, automobile safety glass, textile printing and dyeing and other materials.
1. During the operation of the accelerated weathering tester, you should keep in mind that adequate water sources must be maintained.
2.The time to open the door of the accelerated weathering tester should be reduced as much as possible during the test phase.
3.There are sensing devices in the studio, and you should not be subjected to strong impact.
4.After a long period of discontinuation, if you need to use again, you should carefully check the water source, power supply and components. It must be confirmed that the accelerated weathering tester is ready before starting the accelerated weathering tester.
5.Because ultraviolet radiation has a strong harm to people especially the eyes, operators should minimize exposure to ultraviolet light so that the contact time should be less than 1min. And the operators are advised to wear protective goggles and sheathing.
6.When the accelerated weathering tester is not working, it should be kept dry. Additionally, the running water should be discharged, and the box should be dried.
After use, you should cover the plastic cover to avoid dust intrusion. If there is any dust, you should remove it at once.
