Product Description
The UV aging test mainly simulates the deterioration effect of UV light in sunlight on the product. It also reproduces the damage of rain and dew. The test was conducted by exposing the material to be tested in a controlled interactive cycle of sunlight and moisture, while increasing the temperature. UV fluorescent lamps are used to simulate sunlight, and moisture effects can also be simulated by condensation or spraying.
It only takes several days or weeks, and UV aging tests can reproduce the damage that takes months or years outdoors. The damage caused mainly includes fading, discoloration, brightness decrease, phorization, cracking, blurring, embrittlement, strength decline and oxidation.
Although ultraviolet light (UV) accounts for only 5% of sunlight, it is the main light factor resulting in the reduced durability of outdoor products. This is because the photochemical influence of reactions in sunlight increases with decreasing wavelength. Therefore, it is not necessary to reproduce the entire sunlight spectrum when simulating the destructive effects of sunlight on the physical properties of the material. In most cases, only simulating short-wave UV light is needed. The reason why the UV light acceleration weather resistance test machine uses UV lamps is that they are more stable than other lamp tubes, and can better reproduce the test results. Using a fluorescent UV lamp to simulate the effects of sunlight on physical properties, such as brightness drop, cracking, flaking, etc., is the best method.
Several different UV lights are available. Most of these UV lamps mainly produce UV light rather than visible and infrared light. The main difference of lights are reflected in their differences in the total energy of UV produced in their respective wavelength range. Different lights will produce different test results. The actual exposure application environment can indicate which type of UV lamp should be used.
UVA-340 The best choice for simulating sunlight UV UVA-340 can extremely well simulate the solar spectrum of the critical short wave wavelength range, namely the wavelength range of 295-360nm, UVA-340, producing only a spectrum of UV wavelength that can be found in sunlight. UVB-313 was used for the maximum acceleration test
The UVB-313 can provide the trial results very quickly. Their short wavelength UV is more intense than the UV waves normally found on Earth. Although the UV light, which is much shorter than its natural wavelengths, maximizes the test, it can also cause inconsistent and actual degradation damage to some materials
Standard defines a fluorescent UV lamp emitting light energy below 300nm less than 2% of the total output light energy, usually called UV-A, lamp; emitting 300nm
The following light energy is greater than the total output of a fluorescent UV lamp, commonly referred to as a UV-B lamp. There are two types of exposure methods:
1) After a period of light exposure to the sample, then after the no-irradiation period (when the temperature changes and condensation is formed on the sample). 2) The sample is continuously subjected to irradiation exposure and the cycle test with regular water spray.
The advantages of fluorescent lamp are: quick test results; simplified illumination control; stable spectrum; minimal maintenance; cheap price and reasonable operating costs. There is only a small part of the land on the earth, more than half of the area is the ocean, so the ocean climate is a climate environment that has a great impact on human life and material products.
