About the security measures of UV Rays

Although UV rays are very effective in terms of security measures requires a very simple and easy to understand.
Compliance is important to them. The following general information, you can see detailed information about the measures and requirements.

UV rays
UV rays are dangerous to eyes and skin as a security precautions eder.Genel gerekir.fakat systems with UV-resistant so you do not need it.

UV Protection
At 254nm (UV-C) rays cams normal window (borosilicate, plant and equipment, etc.). Trasparan plastic Makrolon ®, Plexiglass ®, and all opaque materials, especially colored glass filtered UV-C rays pass more etkilidir.Quartz windows so I can not be used as a preservative in eye .
Installation and Usage
Alternative on-off locations, operating instructions, emergency closing locations, based on information provided electricity diagramlarına sorumluluğundadır.Montaj owners should be made by observing experienced people.

Material Resistance
Discards the color of the material after exposure to intense UV radiation in many cases to use materials that resist UV lamps produce a very strong öneririz.Ozon has the effect of oxidation.

Temperature
The use of low pressure lamps, glass lamp to heat the surface of normal fluorescent lamps gb is about 40 º C to 90 ° C with dir.İrrıdyum doped amalgam lamps lamps dir.Medium surface temperature of 100 ° C and 850 º C - 950 º C.
In general, all of these lamps is very easy to contact if flammable things in mind will result in ignition systems bulundurulmalıdır. Bu to be opened again after turning off the lights moved or are already expected to cool thoroughly.
Low pressure lamps, without the need to wait for the cooling process, amalgam lamps for 2-5 minutes, 5-15 minutes should be waited in the medium lamps.

Ultraviolet disinfection Why?

All living things, micro-organisms with genetic information (in cells) of DNA and RNA are called nucleic acids. (Solar home, the doctor does not remember the term). Radyosyonu extraction of nucleic acids when exposed to UV radiation (absorption) properties, which starts the process of Photochemical break down the cell structure of their breeding / reproduction, and growth capabilities, and so the killing will cause the extinction.

This process is repeated several times until the fragmentation of the DNA chain is completely over, and people exposed to radiation within milliseconds gerçekleşir. Sun peeling skin is a simple example is the death of cells that make up tissues.

Use of water treatment UV Rays

ltraviyole rays, the more it is in the background, name unknown, has a very important part in many areas of our lives.

As an example, in many countries, public drinking water taste and unpleasant odor of chlorine found in very specific. This is because the chemicals that are involved in the water, but other times the things that never finds undesirable. The reason for these cases, treatment process, with each passing day more and more popular with the UV Technology is conducted. In the private sector, industry and the medical field, growing with each passing day due to UV technology is used in areas to be more effective and successful results, ease of use compared to conventional systems, the costs to be lower than, the effects and the reliability of the final and it is known everywhere thanks to the use of documentation by the competent institutions in the world is increasing rapidly. That may occur following pages, keep in mind, "How - Where - Why" questions and find the answers.

Who Discovered UV Rays


Two investigators (A. Downes and TP Blunt) has investigated the interaction between UV rays and the development of microorganisms without the sun's rays as a result of micro-organisms in the process showed üreyememeklerini 1878.

For a long time after the dissolution of DNA research and passwords on the lethal UV-C rays, microorganisms and understood completely neutralized the effects of generating.
Who made ​​the first UV lamp?

Richard Kueche quartzla melt quartz glass in 1890 in the first kişiydi.1904 and still in use today's technology, who led the rays of the sun rays are almost completely identical Hanau was the first quartz lamp. For this reason, these lamps are now known as Original Hanau.

Mercury vapor lamps are low pressure as the development of the synthetic production of UV-C rays and thus have been able to be used as a disinfectant.

Over time, UV rays and discovered a lot more about the application area, getirildi.Her be useful for the industry last year, a new field of application is related to the UV rays and are offered to the market.
On the use of UV and on the road can get all kinds of information and support by experienced staff

Care And Use Of Uv Lamp

Touching is recommended to not touch the lamps with bare hands if necessary, using a lint-free cloth and alcohol should be deleted before the use of UV lamp.

UV lamp is used the machine and the working environment is important that short-life care should be taken inappropriate Lambani used under conditions of UV lamps should not be forgotten that the best drying time of 700 hours and 1500 hours, the lamp can be used seamlessly remembered. UV lamp life should be known to be associated with opening and closing ilede Jisan periodically opened and closed quickly to end the life of the lamp burns low-power condition remembered söndürmektense recommended that customers remain.

FAN in the UV curing machines, transformer and reflector must be made to maintain and clean cooling fan cleaning up the essential level of UV lamps, lamp life will be prolonged because uv uv uv lamp transformer settings to be done regularly to work efficiently, effectively able to perform a drying will allow UV lamps are long lasting.

Ultraviolet (UV) Lamp

Ultraviolet (UV) lamp, made ​​of quartz glass, inside is filled with mercury vapor, fluorescent tube-type specific. Ray room, UV-C rays to prevent eye and skin contact directly in order to ensure compliance with food grade 304 stainless steel.

Operating System and Usage

Ultraviolet disinfection, which is the wavelength of 254.7 nm ultraviolet light is used. UV lamps used for disinfection of water, they emit ultraviolet light destroys the DNA of the microorganisms from the water and prevents reproduction. Ultraviolet system should be the area closest to the final use. In addition, the system open to the atmosphere from the water, especially going into a separate unit, and should be used without delay. Turbid waters, to the use of ultra-violet systems, uv water before the unit is capable of handling sensitive particle filters through sediment turbidity removal is necessary. Because organisms, as a result of large particles blocking radiation, the UV unit may live.

Periodic maintenance of the UV lamp is important. Upon completion of the life (9000 hours) must be replaced. Quartz glass, depending on the quality of raw water should be clean. This cleaning Failure to reduce the impact of UV radiation.

Working Principle of UV lamps

Key Facts About UV Radiation and the Formation of• UV lamp Main Operating PrinciplesElectric current through the electrodes pass through the metal vapor discharge lamp. Cathodes, electrons (negative charge) or gas metal atoms colliding electrons spread rise higher energy level. The reaction of collisions with electrons immediately after the completion of radiation energy as they begin to spread. Determining the energy spectrum of radiation is contained in the rebate during the discharge pressure is a determining factor as the metal vapor and gas.• Low Pressure Mercury Vapour UV lamps Home Study FactorsThe pressure of several tons, low pressure mercury vapor discharge lamp, while the reaction of mercury mainly 184.9 nm (185nm) and 253.7 nm (254nm) wavelengths of radiation, but with a choice of different short wavelength of the quartz tube can be prevented dissipation. Wavelengths below 200nm decomposition of oxygen (oxygen is converted to ozone). As a result, the structure of the quartz tube, ozone-producing UV lamp or an important factor in determining the non-producing property to have.High and low pressure mercury vapor lamps disinfect the work is so special about them are very obvious differences. 4cm-150cm long, only 4 for a lamp - a 400Watt power supply range is needed. Some low pressure UV lamps, cold plate electrodes (cold cathode emitters) are performed, some people pre-heat treated (hot cathode emitters) have been active electrodes' are made. In essence cold cathode emitters creates less UV radiation. UV Disinfection procedures for you to get busy with UV dosage we recommend the use of hot-cathode emitters.Low pressure emitters had been burned almost immediately after the maximum level of radiation begins to spread. Low-pressure mercury vapor (low vapor pressure) to be working again very quickly, thanks to ready position after extinguishing the gelirler.Low ateşlenip pressure lamps operate at room temperature to the optimum. Room temperature above and below the lamps which are adapted for places.Medium Pressure lamps, a significant increase in the difference, the dosage of mercury in all mercury discharge has not used the extra time with each, and, furthermore, the ignition and spread of the formation of the fluorescent tube from start to finish during the final electrical arc between the electrodes, there is no limit.These lamps are suitable for running power sources are needed. This choke and ignitor or electronic transformer may be a combination, may account for preferred because of their advantages provided by electronic transformers.• Medium Pressure Mercury Vapour UV lamps Home Study FactorsIf a metal vapor or gas discharge lamp operation from 10 to 20 bar, medium pressure lamps, lamps of this kind happens in this case (as he was called previously, these lamps are high pressure) is called.Medium pressure UV lamp with the main components that make up:• fluorescent tube• A fused-in electricity supply• Electrodes• Gas• MercuryProduced through different stages depending on the application of gas is injected into the quartz tubes. In general, the argon or the mixture of different gases. Pre-calculated and the UV lamp operating voltage determines the injected mercury. In addition to the heavy metal iodide (iodide) to create or mercury spectrumlarındaki spectrumları focused on the points used to fill in the gaps.Foil electrodes and extensions of the fluorescent tube is pressed into the heat of fusion of melt processing and electrical connection, the extension is provided with a tight-knit. Preferably on the voltage applied to electrodes amps limitleyen a conductiveden arc between the electrodes to create the internal gas iyonizeleştirip ısıtacaktır tube to a certain extent.Ignition voltage (approximately 1.7 times the operating voltage) ignition and then again during the fall and rise directly up to 10-50 volts. As a result, many oscillation reaction in the process of mercury and mercury molecules in Vapourise undergoes changes. This process continues until the reaction reached completion, and the electrical values. Electricity when the power source to be ionized gas in the lamp will begin to create from the arc voltage should be determined and the amount of mercury is rising up to the value of certain amount of amps is limited by the power supplies. At the same time after ignition amps predetermined operating level drops (approximately 1.6-fold).Ready during the first ignition of the lamp voltage rise and fall amps until it shows the location of a discharge lamp to the electrical characteristic feature of acceleration values. Based on the foregoing, during firing of the lamp to reflect light from the outside can not be seen in the arc. Arc is captured, but the optimum operating conditions and can be seen in two elektrodtada completed. If the (lamp), or a nominal conditionslar impurities discharge vessel is not reached in this case the arc electrodes can not be fixed and will vary continuously. If a lamp operating voltage in this case, it should be soğutuluyorsa too low to be observed, such as the parameter values ​​of the lamp base can be taken to ensure the optimum operation conditions. In such cases, the minimum power of the lamp where the arc is completely cut off loaded (lamp may be disabled).Due to the high pressure and temperature inside the lamp goes out again immediately after the burn, because it will not be the collision of electrons between the electrodes is not the formation of the arc. Vapor pressure of the lamp is lit the lamp again fall will be arrested in its own specific initial value.Ampere is always required before starting the lamp ignition voltage and the values ​​achieved in flawless condition.
