Sunlight aging test chamber


Sunlight aging tester

I. Overview: Sunlight aging tester, also known as sunlight aging tester, sunlight aging tester, uses a xenon arc lamp that can simulate the full sunlight spectrum to reproduce the destructive light waves that exist in different environments, which can provide corresponding environmental simulation and acceleration tests for scientific research, product development and quality control. It can be used for the selection of new materials, improvement of existing materials or assessment of changes in durability after changes in material composition, and can well simulate the changes produced by exposure of materials to sunlight under different environmental conditions.

Second, the sunlight aging test chamber is designed and manufactured in strict accordance with the technical parameters of GB/T16422.2-99. At the same time in line with (GB/T1865-97, GB/T9344-88, ASTMG155, GB/T16422.2, GB/T2423.24-1995, ISO10SB02/B04, SAEJ2527, SAEJ2412) and other relevant standards.

Three, sunlight aging test chamber technical parameters:

1. Temperature range: RT+10℃～80℃;

2. Black plate temperature: 63℃ ±3℃;

3. Temperature fluctuation: ≤ ± 0.5 ℃;

4. Temperature uniformity: ≤±2.0℃;

5. Humidity range 65～98%R?H;

6. Glass filter: 1 pc;

7. Sample tray size: 251 × 457mm;

8. Xenon lamp source: 1-3 air-cooled, 1 water-cooled;

9. Rainfall time: 1 to 9999 minutes, adjustable;

10. Rainfall cycle: 0 ~ 240min, interval (break) rainfall adjustable;

11. Spraying cycle (spraying time / not spraying time): 18min/102min;

12. Rain water pressure: 0.12 ~ 0.15Mpa;

13. Water spray nozzle aperture: Ф0.8mm;

14. Xenon lamp power: 1.8KW / branch;

15. heating power: 2KW;

16. Sample holder and lamp distance: 230 ~ 280mm;

17. Wavelength: 290 ~ 800nm;

18. Light cycle continuously adjustable, time: 1 ~ 999h, m, s irradiance of 50-100W/㎡;

19. Power requirements: AC220V (± 10%) V / 50HZ two-phase three-wire system;

Fourth, the principle: sunlight aging test chamber is mainly composed of test chamber, light source, temperature and humidity regulation artificial rainfall and other auxiliary facilities. The main technical parameters of the xenon lamp weathering tester are temperature (black plate temperature BPT or black standard humidity BST) humidity, irradiation intensity (290 ~ 800nm, 420nm, 340nm, 300 ~ 400nm) and other optional measurement and control points.
