Description
Technical field
The present invention relates to the technical field of fiber optic cable production, specially a kind of single beam tube great Yu long false proof process.
Background technique
Existing center tube structure sleeving core number is generally 4~12 cores, and casing diameter exists in 2.4~3.0mm, excess length control
1.0~1.5 ‰, the central tube debugging of this structure is relatively easy, usually increases water temperature, suitable wheel rim circle number and takeup tension
It is just able to satisfy technique requirement, this production technology is very common, and debugging difficulty is little, and single great Yu long beam tube, remaining
Length requires 2.0~2.5 ‰, and existing production technology production difficulty is big, because the fewer remaining length of optical fiber is more difficult to do big, composite factor
Very much, such as water temperature, long, material, speed, under normal circumstances, first it is unable to complete more than target as apparatus and process and material lack
Long test, the difference of the diversity and usage that require with user, the requirement of some users is more special, single beam tube
Formula requires to put an optical fiber, and fiber-draw strains the requirement for meeting user again, and to meet pulling tension requirements and length when construction
The pulling tension requirements of phase operation, while the similar products distinguished and gone together, have carried out anti-counterfeit recognition measure；Existing anti-counterfeit recognition is arranged
Generally lettering coding is applied, is easy to be erased, anti-counterfeit capability is bad.
Summary of the invention
In view of the above-mentioned problems, will prevent the present invention provides a kind of single beam tube great Yu long false proof process in production
Pseudo- function is introduced into entire beam tube, and anti-counterfeit capability is good.
A kind of single beam tube great Yu long false proof process, it is characterised in that: optical fiber is sequentially led to releasing under certain laying tension
Ointment filling system and plastic extrusion system are crossed, the outside of the coloured optical fiber of single is successively enclosed with ointment later, pine set forms half
Finished product, the fast PBT material of material selective freezing degree in plastic extrusion system, the PBT material is by blue PBT color masterbatch and this
Mixing is extruded into color PBT material in proportion, guarantees that the beam tube appearance and conventional beam tube have notable difference, so that the beam tube of semi-finished product
Color of the outer surface in the outer surface of conventional beam tube has notable difference.
It is further characterized by:
The surface layer of simple optical fiber in beam tube is coated with blue-colored layer, it is ensured that light in the optical fiber and conventional beam tube in the beam tube
Fibre has notable difference；
Blue-colored layer coating or the coating formation before optical fiber is by ointment filling system in optical fiber coiling in advance；
The PRT material is specially the fast material of crystallinity, and PBT crystallization has substantial connection, semi-finished product with temperature and time
Sequentially passing through the first water-saving groove, water temperature that water temperature is 65 ± 2 DEG C is to enter wheel after 60 ± 2 DEG C of second water-saving groove to lead structure, half at
Product are led in wheel enters water temperature after three circle of suit in structure for 20 ± 2 DEG C of third water-saving grooves, can guarantee remaining grow in production process
In be not consumed, later by semi-finished product by take-up pulley wind carry out take-up, entire producing line speed of production control 80m/min~
100m/min, allowing Loose tube, the residence time is extended in the sink；
The viscosity requirement of fiber paste in the ointment filling system: viscosity >=22000mPa.s, dropping point when reaching 25 DEG C
≥220℃；
Optical fiber laying tension in the pay off rack is 40 ± 5g, guarantees that optical fiber unwrapping wire stabilization is not shaken；
The take-up pressure of the take-up pulley is set as 4N；
The speed of production control of entire producing line guarantees the abundant contraction cooling of PBT material in 100m/min；
The plastic extrusion system is by matching mould, so that wall thickness reaches 0.45~0.50mm.
After adopting the above technical scheme, the PBT material that material selective freezing degree in plastic extrusion system is fast, PBT material
It is mixed and is extruded into proportion with true qualities PBT material by blue PBT color masterbatch, it is obvious poor to guarantee that the beam tube appearance and conventional beam tube have
It is different, so that color of the beam tube outer surface of semi-finished product in the outer surface of conventional beam tube has notable difference, and then the area for passing through color
Dividing can be distinguished with other beam tubes, have no precedent such technology in beam tube production field, false proof process is simple and effective
Reliably and cost is controllable, covers the entire length of beam tube；Antiforge function is introduced into entire beam tube in production by it, is prevented
Pseudo- ability is good.
