Lab Drying Oven UV-A Mathine Climatic Chamber Manufacturer VG95218-2 UV Aging Test Chamber
Product Description The UV weather resistance test box uses fluorescent ultraviolet lamps and condensed water to simulate sunlight and dew conditions respectively. For example: fading, discoloration, loss of light, cracking, turbidity, blistering, embrittlement, strengthening, recession and oxidation, etc. Features The UV accelerated aging test chamber can simulate environmental conditions such as self-climate ultraviolet rays, rain, high temperature, high humidity, dew condensation, darkness, etc. By reproducing these conditions, it is merged into a cycle, and it automatically executes the number of cycles completed. In this process, the equipment can be used for automatic monitoring of blackboard temperature and water tank temperature; by configuring irradiance measurement and control device (optional), the irradiance can be measured and controlled, and the irradiance is stable at 0.76W/m2/340nm or specified setting. Fixed value, greatly extending the service life of lamps. Light source 1.The board temperature,condensing temperature control with controller; 2.The rest are imported electronic components: *Irradiance uniformity:≤4%(At the surface of the sample) 3.Blackboard temperature monitoring:Use standard Pt-100 blackboard temperature sensor,Accurate control of the sample surface temperature during the test process; *Blackboard temperature setting range:BPT 40-75℃； *But the temperature protection inside the machine actual max temperature is 93℃±10% *Blackboard temperature control accuracy:±0.5℃, 4.Tank temperature monitoring: *During the circle test,there's a test section is dark condensation process,it requires high temperature saturated steam inside the chamber,when the steam hits a relatively cold surface of the sample,Dew will condense on the surface of the sample. *The tank is located at the bottom of the chamber,Built-in electric heater; *Tank temperature control range:40~60℃; 5.The test chamber is equipped with a time controller,range 0~530H,backup data for power fail; 6.Safety protection equipment: *Over temperature protection in chamber:when temperature exceed 3℃±10% in chamber,the machine will automatically cut off the supply of the lamp and heater,and go into equilibrium state cooling *Low water tank alarm,Prevent heater from burning Features: 1. UV aging test machine can do two kinds of testing: aging and anti-yellowing. 2. Aging: the machine can promote the increase of sulfur rubber deterioration, to calculate the change rate of tensile and elongation before and after heat. It’s generally thought that test for one day at 70°C, in theory as exposed to the atmosphere for 6 months. 3. Anti-yellowing: the machine stimulate the atmosphere environment, driven by the sun ultraviolet radiation. It’s generally thought that the appearance change at 50°C for 9 hours, in theory as exposed to atmosphere for 6 months. It has the following performance characteristics: The heating mode is the inner tank heating, fast heating and uniform temperature distribution The drainage system uses reflux type and U-type sedimentation device to drain water The distance between the sample surface and the UV lamp plane is 50 mm and parallel The actual studio consists of test samples and supports to form the inner wall of the box, trapezoidal Automatic water refill of tank water level The lid is bidirectional clamshell type, easy to open and close High quality fixed PU movable wheel is used at the bottom of the test chamber
