To promote the development of light industry with excellent products manufacturer, Dongguan Qingda science and technology limited company is the collection of ultraviolet UV development and manufacturing as one of the professional oriented enterprises, is China famous UV machine, UV light curing machine, UV light, UV lamp, UV lamp power supply is one of the production enterprises, more than 300 products its management, in the domestic counterparts in the forefront. Next to introduce the UV ultraviolet light work is how.
The ultraviolet light generated in the discharge of mercury in mercury vapor suspended the inert gas, comprising two electrode and the insulator in a quartz tube. Mercury in the 254 nm, 310 nm and 366 nm to reach the highest point of radiation between 200 and 400 nm.
The quartz cut off the lower wavelengths, do not send any lower than 230 nm radiation. Each atom consists of a nucleus, around a lot of electronic components in a fixed orbit drift. By increasing the energy (electricity) electronic brought in a higher orbit. Each of these elements showed a return to the original state and its trend. The electrons will retreat in the previous track: excessive energy as a photon emitted.
- the tube is made of quartz, because this is the heat transfer of ultraviolet light and at the same time, stand 6 to 800 DEG C only materials. But the most commonly used ultraviolet lamp with dielectric mercury arc lamp or MPMA lights and pressed, it can be produced into a few millimeters to more than 2 meters in length. The lamp life from 1000 to 2500 hours to change.
- the tube will be a little swollen and does have a high melting temperature (1100 degrees C) electrode made of tungsten: their production process is extremely complex. The use of tungsten, is because the curve of the temperature can be increased to more than 3000 DEG C. Molybdenum plate connected to the electrode and wire, and quartz with expansion. And when still can bear high voltage heating.
The light was finally suspended ceramic (or other) insulator. Because the supply current is often enough to a MPMA lamp power, UV ultraviolet light is usually accomplished by transformer.
As a professional UV lighting manufacturer, Dongguan Qingda automation equipment Technology Co., Ltd. will give you a simple introduction to this, if you want to know more details, please visit the company website or call us, Qingda ultraviolet technology to provide customers with UV light source component installation and use, installation of production at the same time also can provide the whole line, give full play to the development and application of UV light curing technology in various fields, I hope to share with you!
