GJB AATCC UV Aging Test Chamber For Electroplating Industry

Equipment summary:

QUV UV aging testing machine can simulate the sun, rain and dew to damage the material, QUV using UV lamp simulate the effect of sunlight, cold rain and dew. Being tested materials are placed in a certain environment which the light and moisture are alternating. The materials are tested for several days or weeks, you can know the damage of material at outside for several months or several years, Damage types include: bleaching, discoloration, loss of light, powder, crack, turbidity, bubble-based, embrittlement, strength decline and oxidation.

Main functions:

UV QUV test machine, the UV lamp can simulate the effect of the sun, condensation and water spray system can simulate the effect of rain and dew. the temperature can be controlled at the process of testing. A typical test cycle is usually testing at UV radiation of high temperature and the 100% humidity at dark; Typically used in paint and coatings, automotive, plastic products, wood products, glue, etc.

Corresponding standard:

Accord with ASTMG53-77, GB﹑GJB﹑MIL﹑ASTM﹑CNS﹑IEC﹑JIS﹑AATCC﹑DIN﹑Fed Test﹑BS﹑SAE,ASTM D4355 ISO-4892,ASTM-G53,D4587,4799,BS-27282,SAE-J2020

Applicable industries:

It is widely used in paint, resins, plastics, printing and packaging, aluminum, adhesives, auto, cosmetics, metals, electronics, electroplating, medicine, etc..

Main feature:

The damage of material durability is mainly caused by the sun's ultraviolet ray. We use UV lamps to simulate sunlight in the ultraviolet part of the short-wave, it produces very little visible or infrared spectral energy. We can choose according to different testing requirements of different wavelengths of UV ultraviolet light, because each lamp in the total energy and wavelength of UV radiation are not the same. Usually, UV lamp can be divided into two kinds of UVA and UVB.

In many outdoor environment, the material wet day time can be up to 12 hours.The results show that this result is the main factor of outdoor wet dew, not rain.QUV condensation through a unique function to simulate the outdoor wet erosion.Condensation during the test cycle, the test chamber at the bottom of the reservoir, water is heated to generate super heated steam to fill the entire test chamber, hot steam to the test chamber maintained at 100% relative humidity, and maintain a relatively high temperature.Sample is fixed in the test room wall, so the test sample surface exposed to ambient air in the test room.The outward face of the sample exposed to the natural environment has a cooling effect, leading to internal and external surface of the sample with temperature, the temperature difference causes the appearance of the sample in the whole process of condensation cycle, the test surface always have condensation of liquid water generated.
 

Irradiation intensity control: optional matching light intensity control option available to accurately type and reproducible results; light intensity control system allows users to set different requirements of different test light intensity. Feedback loop devices through its precise control of light intensity; but also can extend the life of fluorescent lamps

The test box uses a fluorescent ultraviolet lamp as the light source. By simulating the ultraviolet radiation and condensation in natural sunlight, the accelerated weather resistance test is carried out on the material to obtain the result of the weather resistance of the material. It can simulate the environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness, etc. in the natural climate, reproduce these conditions, merge them into a cycle, and let it automatically execute the cycle times.
