UV testing machine

A、Applications

 
1. Uv accelerated aging testing machine is mainly used to simulate the effects of sunlight, humidity and temperature on materials.
 
2. Material aging includes fading, loss of light, strength reduction, cracking, peeling, pulverization and oxidation;
 
3. Ultraviolet aging test chamber by simulated sunlight, imitate the natural moisture, sample test in simulated environment for a few days or weeks of time, can reproduce the outdoor may damage happened a few months or years;
 
4. Ultraviolet light accelerated aging testing machine, uv light of ultraviolet lamp can reproduce the influence of sunlight, water spray system can reproduce the influence of rain and dew.
 
5. The temperature is controllable throughout the test cycle.
6. Typical test cycle usually is uv irradiation and relative humidity at high temperature at 100% dark and humid period;
 
7. Typical application in paint coating, automobile industry, plastic products, wood products, glue, anodized film, etc.

G、Product structure
 
1.The structure of the test chamber is made of corrosion-resistant metal material, including 8 fluorescent UV lamp, water tray, test sample rack and temperature, time control system and indicator.
 
2. Lamp power 40W, lamp length 1200 mm. The working area of the test chamber is in the range of 900 × 210 mm.
 
3. lights installed at the top, a total of 8.
 
4. The test sample is fixedly mounted at a distance of 50 mm from the nearest parallel surface of the lamp surface. The test specimen and its brackets form the inner wall of the box, and their backs are exposed to the cooling air at room temperature. Due to the difference between the test sample and the air in the box The So that the test sample surface of the condensation phase to produce a stable condensation conditions, the test chamber by the bottom of the box through the outer wall and test sample channel to produce natural air convection.
 
5. Water vapor from the heating box low water plate produced, the water depth of not more than 25 mm, and a water supply automatic controller, water plate should be regularly cleaned to prevent the formation of scale.
 
The temperature of the test chamber is measured by a sensor with a width of 75 mm, a height of 100 mm and a thickness of 2.5 mm on a black aluminum plate (blackboard). The blackboard shall be placed in the central area of ​the exposure test. The thermometer shall have a measuring range of 30 ~ 80 ℃, the tolerance is ± 1 ℃ 7. Test chamber should be placed in the temperature of 15 ~ 35 ℃ in the laboratory, 300 mm from the wall, and should prevent the impact of other heat sources, the test room should not be a strong flow of air, So as not to affect the lighting and condensation conditions.
 
7.Drainage system uses vortex-flow type and U type sediment device to drainage which is easy to clean.
 
8.QUV design fit with user-friendly,easy operation, safe and reliable.
 
9.Adjustable speciman setting up thickness,easy installing.
 
10. The upward rotating door do not hinder user operation.
 
11.Unique condesation device only needs tap water to meet demands.
 
12.Water heater is under of container,longtime life and convenient maintainance.
 
13.Water level is controlled out of QUV,easy monitoring.
 
14.Computer programming easy and convenient.                        
 
15.English and chinese manual.
