How to choose UV Weathering Tester for UV aging test
Ultraviolet rays can be divided into three types according to wavelength: UVA (320~400nm), medium wave UVB (290~320nm) and shortwave UVC (200~290nm). UVA has strong penetrating power and can penetrate glass; and it exists throughout the year, regardless of weather, day or night, and the damage to the material is long-term and chronic. Many customers ask how to choose the UV Weathering Tester for ultraviolet aging test ?
The fluorescent ultraviolet lamp source in the anti-UV aging tester simulates the ultraviolet radiation in natural sunlight.
Application range of UV tube: wide range of application. It can be installed in the color light box or other occasions. Such as flaw detection (such as rail detection, etc.), aging test, glue solidification and inspection of paper, fabrics, fluorescent fabrics on fabrics (such as whether the fabrics have phosphorus, etc.), entertainment venues decoration (such as ballrooms, etc.).
UVA-340 UV tube:
UVA-340 is the best choice for simulating the ultraviolet rays of sunlight (photoaging)
UVA-340 can perfectly simulate the sunlight spectrum in the critical shortwave wavelength range, that is, the spectrum in the wavelength range of 295 to 360 nm. UVA-340 only produces a spectrum of UV wavelengths that can be found in sunlight.
UVB-313 ultraviolet light tube:
UVB-313 is used for the maximum accelerated test (accelerated aging)
UVB-313 can provide test results quickly. The short-wavelength UV they use is stronger than the UV light waves commonly found on the surface of the earth today. Although these UV light, which is much shorter than the natural wavelength, can accelerate the test to the greatest extent
UVB penetration is slightly weaker, but due to its high energy, the damage to the material is immediate and serious; while UVC is absorbed by the ozone layer before reaching the ground, and the impact on the material can be ignored.
Therefore, how to choose the UV Weathering Tester for UV aging test needs to be selected according to the customer's finished material.
