Characteristics Of Uv Aging Test Chamber Products And Control Of Radiation Intensity

The UV aging test chamber can simulate the hazards caused by sunlight, rainwater, and dew. UV simulates the effect of sunlight by employing fluorescent UV lamps; condensed water is used to simulate rain and dew in order to complete the sense of being outdoors. In just a few days or weeks, exposure to radiation with ultraviolet rays can duplicate the dangers that occur from being outside for weeks, months, or even years. This can happen even if the exposure time is much less. Because UV has a relatively high radiation intensity, it may be possible to considerably reduce the amount of time needed for testing and simulation using this wavelength. As a consequence of this, it is an excellent medium for determining how effective solar modules are. The presence of UV radiation in natural light is the key component that hastens the process of ageing for materials that are exposed to the outdoors. Photochemical reactions will take occur when UV radiation is present on the surface of an object that has been exposed to the open air for an extended period of time. The object's molecules break apart into atoms, single molecules, or free radicals as a result of these processes. As a consequence of this, the material ages and deteriorates, in addition to causing a number of other phenomena, such the darkening of the fabric, the coating splitting, powdering, and discolouration.

In the UV ageing test chamber, you'll find temperature control and humidity supply systems, in addition to fluorescent UV lights that are designed to most accurately simulate the UV spectrum that occurs naturally in sunshine. These components collaborate to create a simulation of the impacts of ageing on materials. Some of these effects include cracking, peeling, crushing, oxidation, and discoloration. Other consequences include decreasing brightness and intensity. The single light or single moisture resistance of the material either decreases or fails as a result of damage caused by damaging sunlight (UV segment), high temperature, high humidity, condensation, dark cycling, and other causes, as well as the synergistic effect that occurs when UV and moisture interact with one another. This synergistic effect is caused by the fact that damaging sunlight (UV segment), high temperature, and high humidity all contribute to the degradation of the material. As a direct consequence of this, it plays a significant role in the procedure of determining how resistant certain materials are to various environmental factors. This device is easy to run, has relatively low continuing maintenance costs, and produces ultraviolet light that is a very good imitation of the light produced by the sun. A programme controller, which also provides a high degree of automation, great light stability, and outstanding repeatability of test findings, is incorporated into the device, and it is thanks to this controller that the testing cycle is carried out automatically by the device.

The beginning of Dongguan Hongjin Testing Instrument Co., Ltd.'s operations may be traced back to the month of June in 2007. It is a high-tech manufacturing company that specialises in the design and automatic control of large-scale non-standard testing equipment. Some of the types of testing that it performs include simulated environmental testing, testing of material mechanics, optical dimension measurement, vibration impact stress testing, testing of new energy physics, testing of product sealing, and so on and so forth! We are committed to providing our customers with the best level of service that is humanly possible, and we accomplish this goal by adhering to the corporate idea of "quality first, honesty first, committed to innovation, and sincere service," in addition to the quality principle of "striving for excellence."

How To Control The Irradiance Of The Uv Aging Test Chamber?  

1.Light Source Selection:

Irradiance can be altered in a variety of ways, depending on the type of light sources that are used, so it is important to use as many different kinds as possible. The ultraviolet (UV) lamp is not only one of the most popular types of lighting in general but also one of the most prevalent types of lighting that is able to produce ultraviolet light. In order to modify the strength of the irradiance as well as the wavelength of the light that is released by the lamp, various kinds of UV lamps with varied powers are utilised in accordance with the prerequisites of the experiment.

2.Distance Adjustment:

When the distance between the specimen being examined and the source of ultraviolet light is changed, the intensity of the irradiance can be made either more intense or less intense. This is accomplished by adjusting the distance between the two. Irradiance is inversely related to distance, which means that the greater it will be, the closer you are to the source of the light, and the lower it will be, the further away you are from the source of the light.

3.Time Control:

The quantity of irradiance that something gives off can be affected not just by the amount of radiation that it has been exposed to, but also by the length of time that it has been exposed to radiation. The irradiance will be greater if the amount of time spent being exposed to the radiation is for a longer period of time; on the other hand, the irradiance will be lower if the amount of time spent being exposed to the radiation is for a shorter period of time.

4.Cover Filter:

It is possible to eliminate undesired wavelengths of light in a selective manner by making use of a variety of filters that come in a variety of different types. Because of this, it is feasible to change the composition of the irradiance that is being let out into the environment. The strength of the radiation released by different wavelengths, such as UV-A, UV-B, and UV-C, can be controlled by making use of the suitable filters in the appropriate combination. This is made possible by utilising the appropriate combination.

The irradiance of the UV ageing test chamber can be varied in a flexible manner so that it is in conformity with the specific requirements of the test if the processes that were mentioned above are followed to the letter.
