UV aging testing equipment

Equipment summary:

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 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.

Main feature:

1, simulated sunlight

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 eachlamp 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.

2, UV lamp type
UVA-340 lamp: UVA-340 lamps can simulate short-wave UV light in the sunlight excellently, ie sunlight from 365 nm

to 295 nm cutoff wavelength.UVB-313 lamps: UVB-313 lamps are usually issued by short-wave UV radiation than

the Earth's surface in the strong solar ultraviolet radiation, which can speed up the greatest degree of material aging.

However,the lamp may have caused some of the material does not meet the actual damage.UVB313 lamp is mainly

used for quality control and research and development,or on the weatherability of materials strong run the test.

UVA-351 lamp: Simulation of UV sunlight through windows, it is the aging of indoor materials for testing the most

effective.

3, moisture condensation environment
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 superheated

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.

Applicable industries:

It is widely used in paint, resins, plastics, printing and packaging, aluminum, adhesives, auto, cosmetics, metals,

electronics, electroplating, medicine, etc.
