ZN-C mercury lamp aging test chamber has excellent sales

The advantages of fluorescent lamps are: Fast test results Simplified illumination control Stable light spectrum Requires little maintenance Inexpensive 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..., among which the line spectra of and. are 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, power, and can be made into two types: single-ended/double-ended. The principle is that a certain amount of mercury is added inside the lamp, so it is named. The inside of the mercury lamp is in a vacuum state. , 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 vacuum degree inside the lamp and the amount of mercury added, otherwise the lamp cannot emit light or cannot excite light of normal wavelengths. . The light 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, 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

Temperature Control
Cycle
First-order photochemical reactions are not sensitive to temperature changes. However, the speed of the subsequent secondary reaction is closely related to the temperature change. Generally speaking, as the temperature increases, the reaction rate increases. Therefore, temperature control is very important during the exposure test. It is more important to match the test temperature used in the accelerated test with the temperature encountered by the material in actual applications. The temperature setting in the device can be anywhere from ℃ to ℃, depending on the light level and indoor ambient air temperature. The temperature adjustment of the equipment is controlled by a controller with microcomputer calculation function.
