Ultraviolet light test chamber 1. Product use:
The ultraviolet light test chamber uses a fluorescent ultraviolet light as a light source to simulate the weathering resistance of the material by simulating ultraviolet radiation and condensation in natural sunlight to obtain the weather resistance of the material. It is used for abundance of non-metallic materials, organic materials (such as paints, paints, rubber, plastics and their products), and tests the degree of aging of products and materials under the climatic conditions such as sunlight, humidity, temperature and condensation. Get discoloration, fading, etc. in a short time.
Second, the structural characteristics:
1. The box body is machined by CNC machine tool, the shape is beautiful and generous, the cover is bidirectional flip type, easy to operate;
2. The inner bladder of the box adopts imported high-grade stainless steel plate, and the outer casing of the box is sprayed with A3 steel plate, which increases the appearance texture and cleanliness of the ultraviolet light test box;
3. The heating method is the inner tank type heating, the heating is fast, and the temperature distribution is uniform;
4. The water level in the tank is automatically replenished;
5. The drainage system uses the vortex type and U-shaped accumulation device to drain water, which is convenient for users to clean;
6. The sample holder is composed of a gasket and a tension spring, and is made of an aluminum alloy material;
7. The bottom of the UV test chamber is made of high quality fixed PU movable wheel;
Third, the light source:
1. The ultraviolet light test box light source uses 8 UV series fluorescent lamps with a rated power of 40W as the light source, distributed on both sides of the machine, 4 on each side;
2. The surface of the sample is 50 mm apart from the plane of the UV lamp and is parallel;
3. There is UV-B313.UV-A340. Light source for users to choose configuration; (optional)
4. The luminescence spectral energy of the UV-A340 lamp is mainly concentrated near the wavelength of 340 nm;
5. The luminescence spectral energy of the UV-B313 lamp is mainly concentrated near the wavelength of 313 nm;
6. Since the fluorescent light energy output will gradually decay with time, in order to reduce the impact of the test due to the attenuation of light energy, every 1/4 of all 8 lamps have a lifetime of fluorescent lamps.
7. Replace an old tube with a new tube so that the UV source is always composed of a new lamp and an old lamp, resulting in a constant output of light energy;
8. The effective service life of the lamp (made in China for 500-700 hours) (the imported lamps in the United States are around 1800-2000 hours);
Fourth, the control system:
1. The black aluminum plate is connected to the temperature sensor, and the temperature is controlled by the blackboard temperature meter, and the temperature is more stable;
2. The radiometer probe is fixed, no need to load and unload each time;
3. The amount of radiation is measured by a high-precision display and measurement of a special ultraviolet radiation meter;
4. The irradiance is not more than 50W/m2;
5. Illumination and condensation can be independently controlled and can be alternately cycled;
6. The independent control time of illumination and condensation and the time of alternate cycle control can be set arbitrarily within one thousand hours;
7. Automatic detection shows the status of each UV light;
8. Manual adjustment of irradiance and automatic adjustment of irradiance can be achieved and the sample holder can be rotated 360 degrees;
9. The instrument adopts imported LED digital display PID temperature intelligent controller, which has high temperature control precision and good stability;
10. With leakage, short circuit, over temperature, water shortage, over current protection / controller power failure memory;
Five, UV light test box technical parameters:
1. Temperature range: RT + 10 ° C ~ 70 ° C;
2. Humidity range: ≥95% RH;
3. Blackboard temperature: 40 ° C ~ 65 ° C;
4. Distance between lamps: 70mm;
5. Lamp power: 40W / each;
6. Ultraviolet wavelength: 290nm ~ 400nm;
7. Test time: 1～9999s, m, h adjustable;
8. Support sample: 150 × 75 (mm), about 40 pieces;
9. Irradiance can be adjusted: ≤0.33-0.77w/m2;
10. Power requirements: AC380 (±10%) V/50HZ three-phase five-wire system;
Sixth, ultraviolet light test box Product model: UV UV-M UV-A
1. Inner shape size: D × W × H 450 × 1170 × 500: mm;
2. Dimensions: D × W × H 580 × 1280 × 1350: mm;
3. UV: No irradiance adjustment. Temperature control: high precision digital display instrument;
4. VM: Irradiance manual adjustment. Temperature control: high precision digital display instrument;
5. UV-A: The irradiance is automatically adjusted. Temperature control: color LCD touch screen;
Seven, in line with the standard:
The ultraviolet light test box meets the current ultraviolet aging test standards such as GB/T14522-93, GB/T16422.3-1997, GB/T16585-96;
Eight, equipment use conditions:
1. Ambient temperature: 5 ° C ~ +28 ° C (average temperature within 24 hours ≤ 28 ° C);
2. Ambient humidity: ≤85%;
The ultraviolet light test box should not be placed until 80 cm in front, back, left and right;
