Description
Technical field
The solidification of coating is set when the utility model is related to a kind of optic fibre manufacturing technology field, specifically high speed fibre wire drawing
It is standby, especially a kind of high speed fibre wire drawing when fibre coating curing apparatus.
Background technology
The optical fiber for being drawn into suitable dimension by preform needs to coat one or more layers coat as its protective layer.
Typically, bare fibre passes through wet to wet (wet-to-wet) or wet to dry (wet-to-dry) technique applied in two coats or two layers
Coating above.A usual softer undercoating is used to prevent optical fiber from producing micro-bend, and a harder external coating rises to optical fiber
Mechanical protection is acted on, and protects optical fiber to be acted on from external force.The solidification of fibre coating can use heat cure or ultraviolet light (UV)
Solidification.
Ultraviolet light solidification refers to the optical fiber of applying coating being placed in ultraviolet light environments, using in ultraviolet excitation coating
Light trigger so trigger coating crosslink reaction, make its instantaneous solidification into solid material.Recently as optical fiber purchasing price
How persistently dropping for lattice, reduce study hotspot of the cost as optical fiber industry in recent years of optical fiber production process.Improve wire drawing
The speed and then production efficiency for improving optical fiber is to reduce one of direction of optical fiber production cost.Improving the drawing speed of optical fiber needs
Reduce hardening time.
The current more use mercury lamp of drawing process (e.g., high-pressure sodium lamp or mercury xenon lamp) is come needed for producing coating ultra-violet curing
Ultraviolet radioactive.Traditional mercury lamp by the indoor generation electric arc of ionized gas (be usually mercury) with excited atom so as to
It is outer luminous.The shortcoming of mercury lamp is to need substantial amounts of energy consumption to carry out painting of the cured coated on optical fiber to produce the ultraviolet light of sufficient intensity
Layer.Such as, take around 50kw power consumption is used to solidify single layer coating layer to produce the ultraviolet light of sufficient intensity.
Another of mercury lamp has the disadvantage that mercury lamp produces that spectral region is wider, and wavelength is more than 200nm and less than 700nm, generally
The only light of 300nm~400nm wave bands is useful to ultra-violet curing technical process, and the light of this subband only accounts for the light of mercury lamp generation
Spectrum less than 20%, i.e., most of electromagnetic radiation produced by mercury lamp is wasted, and capacity usage ratio is low.Meanwhile, what mercury lamp was produced
Infrared light can produce substantial amounts of heat, it is necessary to additionally increase cooling device to prevent apparatus overheat.
With the development of UV LED (UV LED) technology, UV LED have more as UV radiation sources, UV LED
The long life-span.In general, the life-span of mercury lamp only has 4000~6000 hours, and UV LED life-span can reach that 30000 is small
When.
UV LED another advantage is its environment friendly.UV LED device mercury-frees, and will not be produced during use
Ozone.UV LED devices light source only concentrates on UVA wave bands simultaneously, and the light of harmful UVC wave bands is not produced.
Finally, UV LED only produce the spectrum of 300nm~400nm wave bands, and capacity usage ratio is high.The infrared of heating is not produced
The light of wave band, without extra cooling device.
