Fibre core material described in the present invention adopts polymethylmethacrylate (PMMA).
The material of the sheath described in the present invention can also adopt fire-retardant vinyl chloride (PE), flame-proof polyvinyl chloride (PVC), nylon (PA), TPU, TPR.
A kind of job operation of fire protection flame retarding plastic optical fiber cable may further comprise the steps:
ⅰ at first starts shooting, and machine was heated up about two hours, and before the processing, halogen-free flameproof TPU must be through super-dry;
ⅱ begins to extrude preceding preparation after treating that oven dry is finished:
ⅲ is the optical fiber paying out machine of packing into, and guiding is passed die head and is connected on the bobbin winoler;
ⅳ is ready, and processing temperature is set;
The typical temperature of the drying of the halogen-free flameproof TPU among the ⅰ of step described in the present invention is at 90～110 ℃, and the pre-dried time is 4～6 hours.
The ⅱ of step described in the present invention is described to be prepared to need to guarantee that machine table is thoroughly clean before extruding.
The ⅳ of step described in the present invention arranges processing temperature: one section is 150 ℃, two sections and is 170 ℃, three sections to be 180 ℃, four sections be that 180 ℃, machine neck are that 175 ℃, head are that 175 ℃, moulds are 175 ℃.
Beneficial effect:
Colour circle guarantor of the present invention, Halogen, no red phosphorus; The fire resistance excellence, normal wire gauge all can pass through VW-1.Have good mechanical properties, anti-environment and weatherability have hardness 80A～95A selective.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing and embodiment:
Fig. 1 is one-piece construction synoptic diagram of the present invention.
Embodiment
A kind of fire protection flame retarding plastic optical fiber cable, comprise optical fiber and sheath, optical fiber comprises the reflection horizon 2 in fibre core 1 and the fibre core outside, the reflection horizon 2 in the described fibre core of sheath 3 parcels 1 outside, and adopt environment friendly flame-retardant haloflex (CPE), perhaps the material of sheath can also adopt fire-retardant vinyl chloride (PE), flame-proof polyvinyl chloride (PVC), nylon (PA), TPU, TPR.Core diameter can adopt 0.25mm, 0.5mm, 0.75mm or 1.0mm among the present invention, preferred 1.0mm.Among the present invention the fibre core material adopt polymethylmethacrylate (PMMA).
A kind of job operation of fire protection flame retarding plastic optical fiber cable may further comprise the steps:
ⅰ at first starts shooting, and machine is heated up, and before the processing, halogen-free flameproof TPU must be through super-dry; Typical temperature is at 90～110 ℃, predrying 4～6 hours;
ⅱ begins to extrude preceding preparation after treating that oven dry is finished: guarantee that machine table is thoroughly clean, sordid screw rod, honeycomb plate, head, eye mould can bring very big influence to processing, must keep washing;
ⅲ is the optical fiber paying out machine of packing into, and guiding is passed die head and is connected on the bobbin winoler;
ⅳ is ready, and processing temperature is set: one section (150 ℃) two sections (170 ℃) three sections (180 ℃) four sections (180 ℃) machine necks (175 ℃) heads (175 ℃) eye mould (175 ℃).
Open recirculated cooling water in the processing, optical cable traction after the co-extrusion entered in the chilled water cool off, a silk footpath tester test optical fibre cables outside dimension is set, adjusting screw(rod) rotating speed and drawing tension, guarantee that cable outer diameter is stable, check optical cable lining concentricity, as decentraction, need to adjust extrusion die, the test optical fibre cables decay, as not having significant change, namely to can be considered optical fiber not impaired, produces normally, can close.
The problem that should be noted that in the process:
1. screw speed should be controlled at 12 ~ 60rpm, and it is more slow specifically to decide the more big rotating speed of diameter according to screw diameter, and each hardness material is different;
2. for guaranteeing smooth surface, should add screen cloth;
3. optical cable cooling and typing;
4. notice whether each position temperature of inspection machine is normal, function situation etc.
