2016 Cyclic Mercury Lamp Aging Test Chamber

This mercury lamp testing machine is suitable for performance reliability testing of a variety of industrial products, referring to UV aging test standards such as B/- "Test Methods for Building Waterproof Coatings". Simulation of UV and Sunlight
Although UV light only accounts for sunlight, it is the main lighting factor that causes the durability of outdoor products to decrease. This is because the photochemical effects of sunlight increase as the wavelength decreases. Therefore, it is not necessary to reproduce the entire sunlight spectrum when simulating the damaging effects of sunlight on the physical properties of materials. In most cases, only short-wavelength light needs to be simulated. The reason why UV accelerated weathering testers use lamps is that they are more stable than other lamps and can better reproduce test results. The best method is to use fluorescent lamps to simulate the effects of sunlight on physical properties, such as brightness decrease, cracking, and peeling. There are several different lights available. Most of these lamps produce primarily ultraviolet light rather than visible and infrared light. The main difference between lamps is the total energy they produce in their respective wavelength ranges. Different lights will produce different test results. The actual exposure application environment can indicate which type of lamp should be selected.
The advantages of fluorescent lamps are: rapid test results, simplified illumination control, stable spectrum, low maintenance, low price, and reasonable operating costs.
Ultraviolet high-pressure mercury lamp is a type of gas discharge lamp. It uses bipolar arc discharge to evaporate mercury, thereby producing characteristic spectral lines of mercury vapor. Its spectral lines are mainly in the ultraviolet part, such as 3.,3,.3, Among them, the line spectrum of 3 and 3.3 is extremely dominant, which is very valuable for the curing process, because many photoinitiator systems have strong absorption in this area, so this lamp is also called a curing lamp.
The main wavelength of this lamp is 3, the power is -, and it can be made into single-ended/double-ended leads. The principle is that it is named after a certain amount of mercury is added inside the lamp tube. The inside of the mercury lamp is a Under the vacuum condition, the mercury lamp, under the high voltage excitation of the power supply, atomizes the mercury inside the lamp tube and emits ultraviolet light. There are certain regulations on the degree of vacuum inside the lamp and the amount of mercury added. Otherwise, the lamp cannot emit light or cannot excite normal wavelengths. of light. The luminescence of the ultraviolet high-pressure mercury lamp is accompanied by high heat, because when working at full power, the ultraviolet high-pressure mercury lamp also emits visible light and part of the infrared lamp (R), and the light wavelength is concentrated on the left and right.
Due to frequent exposure to sunlight, the coating layers of wood, including paints and stains, will corrode accordingly. Recent research into structures suggests that the material itself is directly exposed to damaging effects. This process can be repeated many times, resulting in a material degradation phenomenon that cannot be reproduced by thermal means alone.
Use light source
The light source uses one or several high-pressure mercury lamps with a rated power of 0.00000000000000000000000. Placed on the top of the box, there is a reflector on the mercury lamp to more intensively display the superior light source of the mercury lamp
