UV cycle

a

The first-order photochemical reaction is not sensitive to temperature changes. However, the speed of the subsequent secondary reaction is closely related to temperature changes. Generally speaking, as the temperature increases, the reaction rate will accelerate. Therefore, temperature control is crucial during UV exposure testing, and it is even more important to match the test temperature used for accelerated testing with the highest temperature encountered by the material in practical applications. The temperature setting of UV in the device can be any point from 50 ℃ to 80 ℃, depending on the level of illumination and indoor ambient temperature. The temperature regulation of the equipment is controlled by a controller with microcomputer calculation function to command a series of systems inside the equipment, such as air heaters, water heaters, etc.

The damage of natural sunlight to materials causes incalculable economic losses every year, and the UV accelerated weathering testing machine can reproduce the damage caused by sunlight. The device conducts experiments by exposing the tested material to controlled cycles of sunlight while increasing the temperature. The equipment uses ultraviolet fluorescent lamps to simulate sunlight.

2

In just a few days or weeks, the device can reproduce the damage that would take months or years outdoors. The damage caused mainly includes fading, discoloration, decreased brightness, powdering, cracking, blurring, brittleness, decreased strength, and oxidation. The test data provided by the equipment is of great help in selecting new materials, improving existing materials, or evaluating compositional changes that affect product durability. The device can predict the changes that the product will encounter outdoors very well.

3

Simulation of ultraviolet (UV) radiation and sunlight.

4

Although ultraviolet light (UV) only accounts for 5% of sunlight, it is the main lighting factor causing a decrease in the durability of outdoor products. This is because the photochemical reaction of sunlight increases as the wavelength decreases. Therefore, when simulating the destructive effects of sunlight on the physical properties of materials, it is not necessary to reproduce the entire spectrum of sunlight. In most cases, simulating short wave UV light is sufficient.

The reason why UV accelerated weathering testing machines use UV lamps is that they are more stable than other lamps and can better reproduce test results. Using fluorescent UV lamps to simulate the effects of sunlight on physical properties, such as decreased brightness, cracking, peeling, etc., is the best method. There are several different types of UV lamps to choose from. Most of these UV lamps mainly produce ultraviolet light, rather than visible and infrared light. The main difference between lamps lies in the total UV energy they generate within their respective wavelength ranges. Different lights will produce different test results. The actual exposure application environment can indicate which type of UV lamp should be selected.

5

The advantages of fluorescent lamps are: fast acquisition of test results; Simplified illumination control; Stable spectrum; Requiring minimal maintenance; The price is cheap and the operating costs are reasonable.

6

The light source is a UV-A ultraviolet fluorescent lamp imported from the United States. The spectrum of the UV-A ultraviolet lamp is a continuous spectrum, with a spectral distribution range of 280nm to 400nm. The peak intensity of the UV-A spectral wavelength is at 340nm. Therefore, the required experimental spectral irradiance for GB/T19394-2003. NO.5 does not exceed 5 times the corresponding solar irradiance (average sunlight at noon on the equator in summer). The wavelength range and radiation amount of the UV-A340nm ultraviolet fluorescent lamp are most similar.

The effective service life of UV-A fluorescent tubes is about 1800 ± 100 hours. The UV radiometer adopts professional high-quality UV-A and UV-B radiation measuring instruments, and the main meter and sensor are designed to be separated for easy application in various environments.

7

Due to the gradual depletion of the energy output of ultraviolet fluorescent light over time, in order to effectively adjust the experimental process caused by the depletion of radiation energy over time, it is necessary to equip a light radiation energy adjustment system, which can obtain relatively stable light radiation.

8

UVA-340， The best choice for simulating sunlight ultraviolet rays (20 units).

UVA-340 can simulate the critical shortwave wavelength range of sunlight spectrum very well, that is, the spectrum in the wavelength range of 280-320nm. UVA-340 only produces spectra of UV wavelengths that can be found in sunlight.

9

UVB-313， (10 units) used for maximum acceleration testing.

10

UVB-313 can provide test results quickly. The short wavelength UV they use is stronger than the UV light waves commonly found on Earth today. Although these UV lights, which are much shorter than natural wavelengths, can accelerate experiments to the greatest extent possible, they can also cause inconsistent and actual degradation damage to certain materials.

11

A fluorescent ultraviolet lamp that emits light energy below 300nm, which is less than 2% of the total output light energy, is commonly referred to as UV-A lamp; A fluorescent ultraviolet lamp that emits light energy below 300nm, which is greater than 10% of the total output light energy, is commonly referred to as a UV-B lamp.

12

The UV-A wavelength range is 315-400nm, while the UV-B wavelength range is 280-315nm.

The light source uses 23 imported ultraviolet fluorescent lamps with a rated power of 40W as the light source. UV fluorescent tubes are distributed on both sides of the machine, with UVA-340 (20) and UVB-313 (10 units) light sources for users to choose from and configure.

The UV-A wavelength range is 315-400nm, and the luminescence spectrum energy of the lamp is mainly concentrated at the wavelength of 340 nm.

3

The UV-B wavelength range is 280-315nm, and the luminescence spectrum energy of the lamp is mainly concentrated at the wavelength of 313nm.

4

Due to the gradual decay of UV light energy output over time, in order to reduce the experimental impact caused by light energy decay, this test box replaces an old lamp with a new one every 1/4 of the fluorescent lamp life (lamp life: 1800H) among 30 lamps. The position of the new lamp is changed as shown in the figure below, so that the UV light source is always composed of new and old lamps, thus obtaining a constant output of light energy.
