Drum type UV aging test box Product purpose:
Using fluorescent ultraviolet lamps as the light source, the accelerated weather resistance test of the material is conducted by simulating the ultraviolet radiation and condensation in natural sunlight to obtain the results of the material's weather resistance.
The UV aging test chamber device is suitable for conducting water exposure aging tests on non-metallic materials, organic materials, and their products such as coatings, paints, rubber, and plastics. Due to the fact that ultraviolet radiation in sunlight is the main factor causing the oxidation and degradation of polymers, and moisture is an important destructive factor accelerating aging, the degree of product and material aging can be tested under changes in climate conditions such as sunlight, humidity, temperature, and condensation, and discoloration and fading can be obtained in a short period of time. Therefore, this device has the characteristics of simulating outdoor exposure to sunlight and rain aging quickly and conveniently, and has practical value for testing the relative weather resistance of different specimens.

2、 Test box structure:
1. The box material and other components are made of imported SUS304 stainless steel plates, which are aesthetically pleasing*
2. Three ultraviolet light tubes are designed inside the box, installed in an equilateral triangle shape, with a distance of about 70mm between the lamps.
3. Design a rotating sample holder around the periphery of the lamp, rotating 360 ° around the lamp at a speed of approximately 3 revolutions per minute, allowing the sample to evenly receive light from each UV lamp.
4. A spray system is also designed inside the box, which can conduct intermittent rain tests on the samples, simulate the external environment, and provide the samples with the most realistic or rigorous environmental tests.
5. The equipment adopts water heating method to maintain 100% humidity requirement inside. The specially designed automatic water replenishment and overflow system is very convenient and practical.

3、 Rotary drum type ultraviolet aging test box circuit control system:
1. Fully intelligent temperature controller with a control accuracy of ± 0.1 ℃, touch based setting, digital and direct display, with P The function of I. D automatic calculation can reduce the inconvenience caused by manual setting. In operation or setting, if an error occurs, a warning signal will be provided. The test time is adjustable from 0 to 9999H, and the M and S can be adjusted. The maximum timing time for intermittent spraying is 99 hours and 59 minutes. Other electrical components are made of Schneider and high-quality domestic products, which are durable and long-lasting.
2. The control panel is designed with a spray switch, which can be manually controlled by the controller to observe the spray condition and adjust or replace the nozzle accordingly. The sprinkler system simulates temperature fluctuations and rainwater erosion during rain, sprays evenly, and the time can be set according to standards. Users need to prepare pressurized tap water or deionized water.

4、 Test box light source:
1. The light source uses three ultraviolet fluorescent lamps with a rated power of 20W as the light source.
2. Due to the gradual decay of the energy output of fluorescent lamps over time, in order to reduce the impact of light energy decay on the experiment, this test box replaces an old lamp with a new lamp every quarter of the lifespan of all three lamps. This ensures that the ultraviolet light source is always composed of new and old lamps, resulting in a constant output of light energy.
3. The effective service life of the lamp tube can be around 500-700 hours.

5、 Equipment usage conditions:
1. Power supply: AC220（ ±10%）V/50HZ
2. Environment: Temperature of 20-30 ℃ (recommended by ASTM G53), humidity below 80% RH, good ventilation, clean indoor environment.
3. Water source: There is a tap water pipe in the laboratory.
4. Drainage: There needs to be a drainage ditch on the floor near the host.

6、 Compliant with standards:
Design and manufacture in strict accordance with test standards such as GB/T23987-2009 (Artificial weathering exposure of paints and clear coatings to fluorescent ultraviolet radiation and water) and GB/T14522-1993 (Methods for artificial weathering of plastic coatings and rubber);

7、 After sales service:
