UV Accelerated Weathering Chamber

Name: UV Accelerated Weathering Chamber
Brand: Xi'an LIB Environmental Simulation Industry

LIB UV accelerated weathering chamber simulates the destructive effects of ultraviolet radiation, rain, dew, temperature and other factors on materials and products in the natural environment, so as to accelerate the testing of the weathering ability of materials.

UVA (315~400nm) and UVB (280~315nm) two kinds of ultraviolet lamps are used to simulate the damage of aging materials.

Model: UV-SI-260

Standard: ASTM G154, ASTM D 4329 – 05, ASTM C1257, ASTM C1442, ASTM C1519, ASTM C793, ASTM D1148, ASTM D3424, ASTM D3451, ASTM D4101, ASTM D4811, ASTM D6577, ASTM D6662, ASTM D750, ASTM D904, GM 9125P, ISO 29664, ISO 4892-1 (EN) (DIN)

UV Accelerated Weathering Chamber Features and Benefits

1. In a relatively short time, the aging effect of the material exposed to UV light, temperature, humidity and other factors in the natural environment is simulated, and the test cycle is greatly shortened.

2. UV accelerated weathering chamber can truly simulate the impact of ultraviolet radiation and rain, dew and other materials in the natural environment, so that the test results are closer to the actual situation.

3. Equipped with professional UVA-340 lamps and UVB-313 lamps, UVA-340 lamps simulate more powerful short-wave ultraviolet light, UVB-313 lamps have higher energy, and the sample can receive ultraviolet radiation evenly.

4. The inner liner of the chamber is made of SUS304 stainless steel plate, which has good corrosion resistance and high temperature resistance. The outer gallbladder is sprayed with A3 steel plate, which enhances the firmness of the test chamber.

Configuration of UV Accelerated Weathering Chamber

① Control system	Programmable controller (PLC), which can accurately control the ultraviolet radiation intensity, temperature, humidity, test time and other parameters during the test.
② Test sample area	Flat Specimen Holders (aluminum panels with rings). Each specimen size is 75mm*150mm, can hold 52 pieces of specimens. Customize special holder according to different specimens.
③ Radiometer	Mainly used to measure the radiant energy power density of ultraviolet rays.
④ Black panel	Simulate the thermal radiation of the material in the actual use environment.
⑤ Water spray system	Including water tank, water pump, nozzle, water pipe. The tank is used to store water, and the nozzle sprays the water evenly over the test sample, simulating the action of rain or dew.
⑥ Lighting system	UVA-340 lamps and UVB-313 lamps, etc., are divided into two rows, each row of 4 lamps, and maintain a certain distance between the lamps to ensure the uniformity of ultraviolet radiation.
⑦ Heating system	The heating method is the inner tank type heating, the heating speed is fast, and the temperature distribution can be more uniform.
