Fiber coating UV LED for Fiber drawing coloring high speed and high quality
Light-emitting diodes (LEDs) have obtained a considerable market share in ordinary lighting technology. Although the use of LED technology requires a greater investment, this is far outweighed by its benefits – essentially energy savings and long service life.
There is also great interest in LED technology in the sphere of radiation curing. In the course of well over 40 years, the UV lamp with its broad-spectrum has become established in a great many spheres of application. The narrow LED spectrum means that these applications cannot be transferred 1:1. LED UV technology works in the spectral range between 365 nm and 405 nm. UV lamps, on the other hand, cure in a wavelength range up to 450 nm.
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;
