Standards:
Applications:
The UV aging test chamber is suitable for all kinds of geo-synthetics, such as light resistance, weather resistance and light ageing.
The exposure test of the sample was carried out in a fluorescent UV lamp vessel in a controlled environment. It can simulate and strengthen the environmental factors in the natural climate that are affected by light, heat, humidity, and rainfall as the main aging. It can simulate the accelerated test under long term exposure to obtain the results of the weather resistance of the material.
Product Information:
UV Aging Test Chamber is a testing instrument designed to simulate natural environmental conditions, including ultraviolet radiation, temperature, humidity, and condensation, to accelerate the evaluation of material weathering resistance and aging performance.The equipment uses UV fluorescent lamps as the light source to simulate ultraviolet radiation from sunlight. By accelerating the aging process of materials, it evaluates performance changes after long-term outdoor exposure, such as fading, chalking, cracking, embrittlement, and loss of mechanical strength.

Structure and Configuration Description
The structure of the test chamber is made of corrosion-resistant metal material, including 8 fluorescent UV lamp, water tray, test sample rack and touch screen controller.
Lamp power is 40W and lamp length is 1200 mm. The working area of the test chamber is in the range of 900 × 210 mm.
The lamp is installed in a row of four rows, installed in two rows, and the lamp is arranged in parallel, and the center distance of the lamp is 70 mm.
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 support form the inner wall of the box, and their backs are exposed to room temperature cooling air due to the temperature difference between the test sample and the air in the box. So that the test sample surface condensation phase to produce a stable condensation conditions, the test chamber shall be of natural air convection from the bottom of the box through the outer wall of the box and the test sample.
The water vapor is produced by the low water pan of the heating box. The water depth is not more than 25mm, and the water supply automatic control. The water dish should be cleaned regularly to prevent the formation of scale.
The temperature of the test chamber is measured by a sensor with a width of 75 mm, 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 measuring range of the thermometer shall be 30 to 80 ° C , The tolerance is ± 1 ° C. Control of the lighting and condensation stages should be carried out separately, and the condensation stage is controlled by the heated water temperature.
Standard configuration: (1) 12 UV lamp; (2) 21 sets of sample rack
