Product Details

 

Temperature Range: Rt+10°c~70°c Environmental Test Chamber Uv Aging Test Chamber

 

 

UV aging test chamber JD-UV-225L

 

 

First, the use of equipment:

 

The test equipment simulates damage caused by solar ultraviolet light, and the material is subjected to weather resistance test by exposing the test material to light under controlled high temperature. It uses ultraviolet light tubes to simulate the effects of sunlight. In just a few days or weeks, UV-irradiation equipment can reproduce damage that takes months or even years outside, including fading, Color changes, tarnishing, chalking, cracking, cracking, wrinkling, blistering, embrittlement, strength reduction, oxidation, etc., can be used to select new materials, improve existing materials, or evaluate changes in material formulations.

 

 

Second, the device reference picture:

 

 

 

Third, equipment parameters:

 

1. Test box space:

 

2, the inner box size: 500 × 600 × 750mm

Outer box size: 600*900*1200mm

 

3, sample holder: stainless steel

 

4, control instrument: RKC button controller

 

5. The outer shells are made of high-quality (t=1.2mm) A3 steel plate CNC machine tools, and the surface of the outer casing is sprayed, which is clean and beautiful.

 

6. The inner chamber material is made of high quality galvanized sheet, which has the characteristics of acid resistance, corrosion resistance and easy cleaning;

 

7, the sample holder can adjust the position of the upper and lower as needed;

 

8. Since the professional design of experimental equipment based on historical experience, it has a reasonable air circulation system, which makes the cabinet

The highest internal temperature is uniform;

 

9. Distance between the test piece and the surface of the lamp: The highest level of the sample test irradiance is required (the height of the test piece can be adjusted).

 

10, power supply leakage circuit breaker control loop overload short circuit alarm, over temperature alarm

 

 

Fourth, technical parameters

 

1, temperature range: RT + 10 ° C ~ 70 ° C

 

2, temperature uniformity: ± 1.5 ° C

 

3. Temperature fluctuation: ±0.5°C

 

4, the center distance of the lamp: 65-70MM

 

5, the lamp: L = 500 / 40W, 6

 

6, the distance between the sample and the lamp center: 55MM

 

7. Effective irradiation area: 600*500*750MM

 

8, UV wavelength: UVA range is 315-400nm

 

9, test time: 0~999H (adjustable)

 

10, wind speed: 0.5 ~ 1.0m / S

 

11. When the light is simultaneously at a high temperature of 50 degrees, the test day is equivalent to 40 days of outdoor aging.

 

 

V. Equipment use conditions

 

1. Ambient temperature: 5 ° C ~ +32 ° C;

 

2. Ambient humidity: ≤85%;

 

3, power requirements: AC220 (± 10%) V / 50HZ single-phase three-wire system

 

4, pre-installed capacity: 3KW

 

 

Sixth, photovoltaic ultraviolet aging light source

 

1. The center distance of the lamp is 70mm. Refer to the PV industry component size. The size of the solar module is 1680mm, and the calculation of 6 lamps is used.

 

2. Using UVA-340 and UVB-313 fluorescent UV lamps imported from the United States as the light source, by accelerating the weathering test of the material by simulating the ultraviolet radiation in natural sunlight to obtain the weather resistance of the material, the life of the light source is 1800H (hours); The temperature can be automatically monitored, and the temperature can be controlled by the voltage regulator to adjust the irradiance of the lamp to stabilize the irradiance at the specified illuminance and control the test time.

 

3, STT-R series platinum resistance temperature sensor; is made of stainless steel casing, filled with heat-conducting material and sealing material, small size, excellent waterproof and shockproof performance, up to IP67.

 

 

Seven, UVA lamp (detailed)

 

Referred to as UVA:

It is ultraviolet light with a wavelength of 320-400 nm. Long-wave UV is more penetrating to clothing and human skin than UVB. It can reach deep in the dermis and can act on melanin in the epidermis, causing skin melanin to darken and darken the skin. Protects the skin. Therefore, long-wave ultraviolet rays are also called "tanning". Although long-wave ultraviolet rays do not cause acute inflammation of the skin, they have a slow effect on the skin and can accumulate for a long time, which is one of the causes of skin aging and serious damage.

 

Ultraviolet rays are classified according to wavelength:

Near ultraviolet UVA, far ultraviolet UVB and ultra short UVUV. The degree of penetration of ultraviolet light on human skin is different. The shorter the wavelength of ultraviolet light, the greater the damage to human skin. Short-wave UV rays can pass through the dermis, while medium waves can enter the dermis.

 

 

Eight, after-sales technical services:

  • Under the conditions of product precautions, installation and use rules, the product will be free of charge within one year from the date of shipment due to the quality of the product itself, and will be responsible for life-long maintenance service.
