Product Details

ZN-C-GB/T16777 standard high voltage (medium voltage) ultraviolet aging test chamber

This product refers to item 7.1.7 of GB/T16777-1997 Test Methods for Building Waterproof Coatings. The UV aging chamber is a 500W straight high-pressure mercury lamp, with the lamp tube parallel to the bottom of the chamber and the chamber size of 600mm × 500mm × 800mm. The test piece is placed on a glazed brick and then placed together in a 500W straight high-pressure mercury lamp UV radiation chamber, with the lamp tube parallel to the bottom of the chamber and a distance of 47mm-50mm from the test piece. The temperature of the space about 50mm away from the surface of the test piece is (45 ± 2) ℃. After constant temperature irradiation for 240 hours, the test is carried out according to the provisions of 7.2.2.

2、 Light source

1. The UV aging test chamber includes UV irradiation and dark cycle functions, and users can set the time for both functions by themselves; The total test time is equipped with a power-off hold function, which automatically resumes operation after power is restored. The machine uses a 500W ultraviolet high-pressure mercury lamp as the light source, and conducts accelerated weather resistance tests on the material by simulating the ultraviolet radiation state in natural sunlight (such as 40 ℃) to obtain the results of the material's weather resistance. The effective service life of the lamp tube can be around 1000 hours.

2. Our company's constant temperature structure design is convenient for users to operate.

3、 Equipment usage environment:

1. Environmental temperature: 5 ℃~+28 ℃ (average temperature within 24 hours ≤ 28 ℃)

2. Environmental humidity: ≤ 85% R.H

PS: The operating environment needs to be below room temperature of 28 degrees Celsius and well ventilated.

4、 Precautions

1. Do not exceed 60 ℃ for UV testing.

2. During the experimental phase, the time for opening the box door should be minimized as much as possible.

3. The sensing devices in the studio should not be subjected to strong impacts.

4. Non dedicated operators are not allowed to operate at will.

5. The irradiance probe wire is an optical fiber, so it cannot be pulled or bent at will.

6. When the device encounters a malfunction that cannot be resolved by itself, please contact our company.

7. After a long period of disuse, if it is necessary to use it again, the power supply and all components must be carefully checked to ensure accuracy before restarting the equipment.

8. Due to the strong harm of ultraviolet radiation to personnel (especially eyes), operators should try to minimize exposure to ultraviolet radiation (exposure time should be less than 1 minute). It is recommended that operators wear protective goggles and sheaths.
