The ultraviolet weather resistance test chamber is to simulate the damage caused by the strongest ultraviolet rays in summer, and it can also simulate environmental conditions such as rain, high temperature, high humidity, condensation, and darkness. Loop and let it execute automatically to complete the number of loops. The experiment has a realistic natural climate, using fluorescent ultraviolet lamps as the light source. By simulating the ultraviolet radiation and condensation in natural sunlight, the material is subjected to accelerated weather resistance tests to obtain the results of the material weather resistance.
Only by doing the preparation work before the test and providing a standard use site, under a good environment, can the equipment play its best condition for the test. The following are the installation environment requirements and matters summarized by the author's years of experience.
Installation environment requirements and matters:
1. The test chamber should be placed firmly on a flat site away from strong airflow and strong magnetic field interference.
2. The test box should be reliably grounded.
3. The ambient temperature of the test chamber should not exceed 30 ℃, and the temperature and air temperature should be 21 ～ 27 ℃.
4. Carefully remove dust, rust, dirt and residual water stains from the test area.
5. Open the door and inject deionized water into the bottom of the test chamber. The conductivity of the water is <5us / cm, the solid solution in the water is <1ppm, and the silica is <0.1ppm. The water surface should be close to the drain grid.
6. Prepare a control sample panel with similar composition and structure and the same specifications as the sample. The control sample panel can confirm its performance through standard outdoor exposure test or other methods. Ideally, the failure mode and the tested material have relatively good durability and the other has relatively poor durability. In order to ensure the statistical evaluation of the test results, various samples and control samples should be prepared in duplicates.
7. Install the sample and control template on the sample turret to ensure reliable clamping and symmetrical distribution. It is recommended to fill blank samples in vacant positions to maintain consistent test conditions.
8. Close the door.
Health Balls were made roughly 2000 years ago in China. They used to be used for martial arts training. Eventually, it was solely for the us of the Imperial family. Today, health balls are a treasured necessity for Chinese people. It helps to build up strength and to promote health.
These Melodious Balls are known for their healing powers! To use, rotate together in your palm clockwise or counter clockwise to feel the relaxation. Each set of health balls comes in its own highly decorative case.
