Fiber coating UV LED for Fiber drawing coloring high speed and high
quality
Print quality benefits:
Less dot gain；UV inks&LED inks cure instantly exposed to
ultraviolet light. This keeps the ink on top of the substrates with
less dot gain, resulting in crisper imagery and more vibrant
consistent colors
More flexibility:
Instant curing also allows design flexibility for printing on a
wider variety of papers, plastics, and foils. The ultra-violet
printing process also enables visual effects and tactile textures
to be applied to the press, saving time and money
Fiber coating curing is a highly skilled process. In the fiber
drawing tower, it is produced at a speed of 2km per minute. The UV
curing process determines the quality of the fiber. Traditional
curing methods consume a lot of electricity, generate a lot of
heat, and have high maintenance costs. UV LED technology makes up
for the traditional UV-cured shortboard, which is a new,
energy-saving and efficient technology.
For every 1 centimeter of fiber produced, the LED UV lamp and the
extraction system use approximately 0.5-0.7 degrees of power. We
produced about 240 million core kilometers of fiber in 2018 in
China, and the total power consumption will exceed 160 million kWh.
Compare with conventional UV lamp
1. For every 1 centimeter of fiber produced, the LED UV lamp and
the extraction system use approximately 0.5-0.7 degrees of power.
2. We produced about 240 million core kilometers of fiber in 2018
in China, and the total power consumption will exceed 160 million
kWh.
3. UV-LEDs are five times more efficient than mercury lamps.
4. If UVLED is applied for optical fiber production in 2018, it can
save RMB256 million(It's the visible cost).
5. Invisible cost : Extracting the heat generated by the drawing
tower area and maintaining the constant temperature of the
cleanroom( 23-26°C & 50% RH); the high curing efficiency of UVLED
peak intensity can increase the drawing capacity; but the heat
generated by mercury lamp will cool the exhaust system, and the
cost of consumables in the mercury lamp use process;
