Uv Aging Testing Chamber Equipment For Plastic Standard Accord With Astmg53-77 Customized Size Oem Odm Service UVA340

Uv Test Chamber also known as a UV weathering chamber or UV accelerated aging chamber, is a specialized piece of equipment used to simulate the effects of long-term exposure to ultraviolet (UV) radiation on materials, products, and components. These chambers are commonly used in industries such as automotive, aerospace, coatings, plastics, and textiles to evaluate the durability and performance of materials under accelerated UV aging conditions. It can simulate the ultraviolet ray in the sun, rain and dew to damage the material, QUV using UV lamp simulate the effect ultraviolet ray of sunlight, cold rain and dew. Being tested materials are placed in a certain environment which the light and moisture are alternating.

1. Simulated Sunlight
The damage of material durability is mainly caused by the sun's ultraviolet ray, 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.

2. UV Lamp Type
UVA-340 lamp: UVA-340 lamps can simulate short-wave UV light in the sunlight excellently, ie sunlight from 365nm to 295nm 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.
UVA-351 lamp: Simulation of UV sunlight through windows, it is the aging of indoor materials for testing the most effective.


3. Temperature Control:
The temperature control in each cycle, the temperature can be controlled at a set value.At the same time the board can monitor the temperature of the thermometer.Higher temperature can accelerate the aging process, while temperature control for reproducibility of the test is also very important.

4. Water Spray System:
Sprinkler system with 12 nozzles, each side in the test room of 6; sprinkler system can run a few minutes and then shut down.This short cooling water samples quickly and create a thermal shock conditions.

The purpose of UV aging testing is to assess how materials and products will hold up when exposed to sunlight or other UV sources over an extended period. UV radiation can cause degradation, discoloration, fading, embrittlement, and other undesirable effects in many materials. By subjecting samples to controlled UV exposure in a testing chamber, manufacturers and researchers can predict and study the effects of long-term UV exposure in a relatively short period of time.

UV aging testing chambers typically consist of a chamber or cabinet with specialized UV lamps that emit UV radiation similar to natural sunlight. The intensity and spectrum of the UV radiation can be adjusted to simulate different environmental conditions. The samples to be tested are placed inside the chamber and exposed to the UV radiation for a specified duration, which can range from a few hours to several hundred hours or more, depending on the desired level of accelerated aging.

During the UV aging process, the chamber may also incorporate other environmental factors such as temperature and humidity control to further simulate real-world conditions. This allows for a more comprehensive assessment of how materials will perform when exposed to a combination of UV radiation and other environmental stressors.

Uv Test Chamber Main Functions
The materials are tested for several days or weeks, you can know the damage types include: bleaching, discoloration,
loss of light, powder, crack, turbidity, bubble-based, embrittlement, strength decline and oxidation.
