Whether the effect of ultraviolet germicidal lamps is good or not is mainly affected by the following factors:
One: Glass materials, there are high boron glass, quartz glass, synthetic quartz glass.
High boron glass: also known as soft glass, it only needs three or four hundred degrees of fire temperature to be softened for processing, only 254nm band (no ozone) is generated, and no ozone is generated.
Quartz glass: It needs a fire of 1800 degrees to be soft and processed. It cools and hardens immediately after the fire leaves. It is very difficult to make. It can be made with or without ozone. The ultraviolet transmittance, hydroxyl content, purity and impurity content of quartz glass, These data are very good. The more ultraviolet rays that pass through, the better the sterilization effect. There are many manufacturers of quartz glass on the market, and the quality is uneven. The price per kilogram of glass varies greatly, so the price of the lamp is also different. It is very big. Although it is said that the user can't see it, it is good to know that the lamp is on. However, it is completely unknown whether the ultraviolet sterilization effect is still there. It is better to know more about the strength of the manufacturer before purchasing. Self-control to evaluate.
Synthetic quartz glass: Not much to say about this, glass is very expensive, very expensive, very expensive. Of course, it goes without saying that the light tube produced has a very good transmittance and very little attenuation, and the effect is naturally good. The production cost is too high. Generally, if it is necessary for scientific research and experiments, we will find us to customize the lamp.
In addition, let's talk about the attenuation of quartz glass, what is the principle? Ultraviolet rays irradiate the wall of the glass tube for a long time. The glass is a single crystal of silicon dioxide. The long-term irradiation will change, and the holes that can transmit ultraviolet rays will be blocked. Therefore, the ultraviolet rays of the lamp tubes are attenuated. Generally, lamp manufacturers will mark the lamp tube. How long is the lifespan? Although the lamp is still on when the time is up, the ultraviolet rays are already very small, and the effect of the newly produced lamp is not as good. That's why.
Two: The production process is good or not.
To make a quartz ultraviolet germicidal lamp, there are still many processes. There are dozens of processes, large and small, but only the main processes are briefly mentioned.
Clamping process: Whether this process is done well or not directly affects whether the lamp tube will leak or slowly leak. The expansion coefficients of molybdenum sheet and quartz glass are close, so molybdenum sheet and quartz glass are used for sealing. After the phase is clamped, the sealing is completed. Whether the fire is well adjusted will affect whether the glass is soft enough to burn. very critical.
Exhaust process: After the lamp tube is sealed, it needs to be vacuumed to remove the air, impurities, and impurities in the wick. It needs to be baked at high temperature while pumping. Baking time, power-on time of each gear, etc. Whether the vacuum degree is high or not will affect the life of the lamp tube, and the exhaust process is a very important process. After the exhaust is completed, the capillary is basically completed. After that, the lamp tube is matured, and the lamp holder is assembled." "With the promotion of emerging UV coatings, inks and other photopolymer materials and ultraviolet radiation light sources, the use of ultraviolet high-pressure mercury lamps in printing and coating industries has become more and more widespread, but because the operators do not know much about this technology, use There have also been many problems in China. As a manufacturer of UV light sources, we will inform you of the precautions as follows:
1. The ultraviolet lamp tube must be matched with the same matched ballast, magnetic leakage transformer and capacitor before it can be used.
2. It must be installed in accordance with the wiring diagram provided by the manufacturer.
3. The light box in which the lamp is installed must be equipped with a good air cooling system to ensure the heat dissipation of the lamp and prevent the substrate from being thermally deformed.
4. Before the tube is put on the machine, it is necessary to wipe off the fingerprints and oil stains on the outer wall of the lamp with gauze and alcohol, otherwise it will cause the lamp to lose transparency after ignition. If the UV curing material has a higher content of volatile solvents or work The environment is polluted by dust. Please wipe the lamp with alcohol every other week to ensure that the lamp does not devitrify prematurely.
5. During the whole use process, keep good contact between the lamp cap and the contact point of the lamp, otherwise it will cause serious oxidation of the lamp cap and cause the lamp tube seal to burst.
6. The UV lamp can only be started when it is cooled down. ; When restarting, you need to wait for the UV lamp to completely cool down before starting. After 5 minutes; the more frequent the switch, the shorter the lamp life.
7. The average lifespan of the high-pressure mercury lamp of Ningbo UV Light & Electricity is 8000-1000 hours, and the surface temperature of the lamp tube is 600~700℃ during normal operation. Mainly related to the number of lamp starts.
8. It is strictly forbidden for the lamp and transformer to work in an overloaded state to avoid lamp explosion or transformer burn-out accidents. The power supply voltage should not fluctuate too much. If it drops suddenly by more than 5%, it may go out by itself. Anything that caused the lamp to burst due to the burning of the lamp cap is not the internal quality of the lamp, and it is purely improper use and will not be returned.
9. The transformer must have good natural ventilation conditions for heat dissipation.
