Gold medal supplier of rotating drum desktop UV weather resistance test chamber

The UV weather resistance test chamber uses fluorescent UV lamps as the light source to perform accelerated weather resistance tests on materials by simulating ultraviolet radiation and condensation in natural sunlight to obtain the results of material weather resistance.
This device is suitable for water exposure aging experiments on non-metallic materials, organic materials and their products such as coatings, paints, rubber and plastics. Since ultraviolet rays in sunlight are the main factor causing oxidative degradation of polymers, and moisture is an important destructive factor that accelerates aging, the aging of related products and materials has been tested under changes in climate conditions such as sunlight, humidity, temperature, and condensation. According to the degree of phenomenon, discoloration, fading, etc. can be obtained in a short time, so this device can quickly and easily simulate the aging characteristics of outdoor exposure to sun and rain, and has practical value for testing the relative weather resistance of different specimens.
This equipment simulates ultraviolet light, condensation, heating, and rain tests, and is applicable to /. standards.

2. Structure
The box material and other components are made of imported stainless steel plates, which are beautiful and non-corrosive. There are three UV lamps designed inside the box. , installed in an equilateral triangle shape, the distance between lights is approximately. A rotating sample holder is designed around the lamp and rotates around the lamp. The rotation speed is adjustable at about one minute, so that the sample can evenly receive the illumination of each UV lamp. The equipment is equipped with an anti-sample rack slip-off device to prevent the sample rack from slipping and causing damage to the lamp and machine.
A spray system is also designed in the box, which can conduct intermittent rain tests on samples to simulate the external environment, so that the samples can be tested in real or the most severe environment. The equipment uses water heating to maintain the internal % humidity requirements. The specially designed automatic water replenishment and water self-overflow system is very convenient and practical.
3. Circuit control system
Intelligent temperature controller imported from South Korea or Shidenden and Fuji from Japan, with control accuracy of .℃, touch-sensitive setting, digital and direct display, and automatic calculation Function can reduce the inconvenience caused by manual setting. If an error occurs during operation or setting, a warning signal will be provided. The test time is ~ adjustable, and the maximum spray interval time is hours and minutes. Other electrical components are made of Schneider and domestic high-quality products, which are durable.
Spray adjustment
The operation panel is designed with a spray switch. Using the manual control function of the controller, you can observe the spray status and adjust or replace the sprinkler head. The spray device simulates drastic temperature changes and rainwater erosion when it rains, sprays evenly, and the time can be set according to standards.
Users need to prepare pressurized tap water or deionized water.
4. Light source
The light source uses ultraviolet fluorescent lamp with rated power as the light source.
Since the energy output of fluorescent light will gradually attenuate over time, in order to reduce the impact of the test caused by the attenuation of light energy, this test box is equipped with a A new lamp replaces an old lamp. In this way, the ultraviolet light source is always composed of a new lamp and an old lamp, thereby obtaining a constant light energy output.
, The effective service life of the lamp can be about hours.
5. Equipment usage conditions
