Introduction: uv lamp is actually friends often heard of ultraviolet lamps, the main principle of the product is based on the photochemical reaction to achieve the two ends of the lamp electrodes to provide a certain difference in the presence of voltage difference and thus the emergence of ionic discharges, but also to carry out a certain amount of ultraviolet radiation control, uv lamps are very much in the role of the application of the field is also very broad, both in the medical Inspection or in the product curing can see the figure of uv lamp. The following for the role of uv lamps can help you bring a more comprehensive introduction, so that you really have to understand.
With the continuous development of uv lamp technology, the product has been put into use in large quantities in the production of life, uv lamp power is generally in the 100W or so, the product service life is generally in 1000 hours. Want to make the product play a better use of the effect is usually recommended to friends of the two uv lamps to replace the use, so that you can minimize the long time to work and produce faults. uv lamps this to see the following to understand it.
?uv lamp roleUV lamp in the role of spraying is indispensable, a lot of cosmetics or electronic products shell spraying must be through the uv lamp irradiation to be able to irradiate the need for 8 lamps *** with the same role, so as to ensure that the color of the parameters of the function of the more in line with the customer's requirements, the uv lamp in many processing plants. Now uv lamps in many processing plants are essential spare parts products, buy uv lamps when friends must also choose qualified manufacturers, so as to ensure that the performance and life of the lamps and lanterns are guaranteed.
UV lamps play a great role in the printing of the reverse side, for example, the production of CD-ROMs need to be uv lamp irradiation, so that the CD can be played more smoothly, it is also worth mentioning that uv lamp irradiation can increase the drying speed of the product, but also to enhance the adhesion of the product, so that the indicators are maintained in the scope of the standard, in the production of shoes after the uv light can be irradiated to make the sole material undergo rapid chemical reaction. In the shoe industry, the UV lamp irradiation can allow the sole material to undergo a rapid chemical reaction to achieve a better adhesive effect.
Advantages and effects of UV lamp sterilization
The usual UV lamps are made of quartz because it is the only material that transmits UV light and at the same time endures high temperatures from 6 to 800°C. The lamps will expand a little and will be able to withstand high temperatures. The lamps will expand a little and do have a high melting temperature (1100°C). The electrodes are made of tungsten:? The process of producing them is extremely complicated. Tungsten is used because the temperature of the curve can rise to over 3000°C. Molybdenum plates are used to connect the electrodes to the wires, which can expand with the quartz. and can still tolerate high voltages when heated. The lamp is finally suspended into a ceramic? (or other) insulator. ?UV light-setting machines also work on the UV light principle.
The advantages of using UV UV lamps for disinfection are roughly fourfold:
1, UV disinfection does not require chemicals, and does not produce THMs type disinfection by-products.
2, fast sterilization, good results.
3, no odor, no noise, does not affect the taste of water.
4, easy to operate, simple management, low operating and maintenance costs.
Professional UV UV lamps are determined by the microbial dose of reflection, at the same time, but also by the output energy of ultraviolet light, and the type of lamp, light intensity and application time related to the lamp, with the aging of the lamp, it will lose 30% -50% of the intensity. UV light solidification machine performance depends on its degree of absorption of UV light.? UV reflection dose is to reach a certain bacterial inactivation rate, the amount of a specific wavelength of ultraviolet light required: reflection dose (J/m2) = reflection time (s) × UVC intensity (W/m2) the larger the reflection dose, disinfection? The higher the efficiency, due to the size of the equipment requirements, the ordinary reflection time as long as a few seconds, therefore, the UVC output intensity of the lamp has become a trade-off between UV onclick="g (disinfection equipment);"> disinfection equipment? Performance of the most important parameters. In urban wastewater disinfection, the common uniform reflection dose in 300?J/m2 or more. Below this value, it is possible to present the phenomenon of gram resurrection, that is, the germs can not be completely killed, when the outflow from the channel to withstand the visible light reflection, re-survival, reducing the sterilization effect. In addition to the environment also has sterilization, deodorization, purification effect.
The role of the uv lamp in the above has helped friends to make an introduction, friends should know that want uv lamp better role must also be in the use of special attention must be to choose the matching power supply for the product, to ensure that the uv lamp use the voltage and current are in a fixed range, the use of the appropriate fan must also be matched with the uv lamp sub ah can achieve a better surface of the lamp! Cooling effect, so that the role of the uv lamp to play a more comprehensive, to achieve better results.
