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.
