Produce sealing impregnation pultrusion system and device and the preparation method of optical cable strengthening core
Technical field
The present invention relates to the device and method of optical cable strengthening core, be specifically related to produce sealing impregnation pultrusion system and device and the preparation method of optical cable strengthening core.
Background technology
In order to strengthen the hot strength of communication cable, optical cable inside all is provided with the reinforcement core.Figure 1 shows that existing communication cable structure chart, optical cable inside is provided with five five core optical cables, five five core optical cable centers are provided with a strengthening core, be coated with the loose sleeve pipe of a circle on the external diameter of five core optical cables, be connected with the sleeve pipe filler between optical cable and the optical cable, be connected with the cable core filler between pine sleeve pipe and the loose sleeve pipe, coat on the cable core filler external diameter and be connected with a circle plastic-coated steel band, coat on the plastic-coated steel band external diameter and be connected with a circle pe sheath, the past generally adopts steel wire as the reinforcement core of optical cable, but because there is corrosion-resistant in steel wire, normal operation 1-2 will corrosion, and the generation pernicious gas, cause hydrogen loss, affect the optical fibre transmission performance.In addition, because steel wire has electric conductivity, under high-tension electricity and effects of lightning, induced-current can be produced, performance and the signal transmission quality of optical cable can be affected.Therefore, there is not long defective in service life in this steel wire strengthening core
Development along with science and technology, the traditional alkali-free glass fibre silk of a kind of employing, the dipping vinylite, by mould heating resin solidification, adopt continuous pultrude process to produce the composite material optical cable strengthening core, Fig. 2, Figure 3 shows that FRP or KFRP pultrude process, having replaced steel wire becomes novel optical cable strengthening core as strengthening core.The equipment and process that adopts is open steeping vat, existing manufacturer production FRP or KFRP optical cable strengthening core, and the resin-based of selecting is vinylite and a small amount of curing agent and promoter (BPO-TBPB).And in the vinylite styrene-content greatly about about 30%-40%.
As everyone knows, open steeping vat is if polymerization and oxidation can occur among being exposed to air in styrene gradually.Existence is very large to health and environmental hazard, simultaneously water body, soil and atmosphere is polluted.If meet naked light, high temperature or oxidant contact, there is the combustion explosion of causing dangerous, the eyes of human body and respiratory mucosa are had to stimulate and anesthetic effect.If labourer protects improper, then can cause headache, weak, vomiting, anorexia, abdominal distension, melancholy, forgetful, refer to quiver etc.Long Term Contact, the defective such as sometimes also cause obstructive lung pathology, pachylosis cracking and thicken.
Summary of the invention
Purpose one of the present invention provides a kind of simple in structure, easy to use, and is pollution-free to atmosphere, to the sealing impregnation pultrusion system and device of workman's health without the production optical cable strengthening core of injury.
Another object of the present invention provides the preparation method that this device is produced optical cable strengthening core.
In order to overcome the deficiencies in the prior art, technical scheme of the present invention is to solve like this: produce the sealing impregnation pultrusion system and device of optical cable strengthening core by fibre glass roving creel arrangement apparatus, yarn guide, glue groove, preforming mould, hot briquetting mould, mechanical type draw-gear, closed reel garden installation composition; Improvements of the present invention are that interval, described yarn guide right side arranges an infrared heating moisture discharge device, heating interval, moisture discharge device right side arranges a sealing load gumming device, a transparent sealing storage glue tank upper end is connected with glue-feeder with pipeline by the 1# valve, described transparent sealing storage glue tank lower end is connected with the sealing load gumming device with pipeline by the 2# valve, the bottom of described sealing load gumming device is connected with the binder removal mouth with pipeline by the 3# valve, the terminal part of described sealing load gumming device is connected with vacuum pumping pump with pipeline by the 4# valve, the interval, terminal part right side of described sealing load gumming device arranges a hot briquetting mould, and the optical cable strengthening core of hot briquetting draws to closed reel garden device by the mechanical type draw-gear.
A kind of described sealing impregnation pultrusion system and device is produced the preparation method of optical cable strengthening core, carries out in the steps below:
(1), on demand product specification is selected arrange glass fibre or aramid fiber;
(2), open the infrared heating moisture discharge device, with 150 ℃~200 ℃ oven dry glass fibres or aramid fiber;
(3), open the hot briquetting mould, with 120 ℃~150 ℃ heating moulds;
(4), open the 1# valve, will after closing the 2# valve, put into transparent sealing storage glue tank by the vinylite sizing material that vacuum stirring is crossed;
(5), mold temperature to be heated begins to sealing load gumming device injecting glue after being raised to the technological temperature of setting; Step is: close 2# valve, 3# valve, open vavuum pump and vacuumize and open the 4# valve, vacuum is the 0.8-1 MPa, closes the 4# valve after the vacuum that reaches setting;
(6), open the 2# valve, treat that the vinylite sizing material piles the sealing load gumming device;
(7), the hauling speed of pressing technique initialization opens draw-gear, optical cable strengthening core is drawn to closed reel garden device;
(8), after the optical cable strengthening core pultrusion finishes a circulation, remaining vinyl sizing material is got rid of by the 3rd valve (3) in the sealing load gumming device.
(9), in the whole production process, if descending, can add at any time by transparent sealing glue tank glue.
The present invention compared with prior art, have simple in structure, easy to use, pollution-free to atmosphere, to workman's health without the injury characteristics, contain cinnamic resin sizing material fully in the device of a sealing.The optical cable strengthening core product corrosion resistance of producing is strong, can not get rusty, and can not cause hydrogen loss, can not affect the signal propagation performance of optical fiber, and is insensitive to shocking by electricity, and is applicable to the climatic environments such as many thunders and lightnings are rainy area, can adjacent power line and supply unit install.Not disturbed by the induction power supply of its generation, compare with metal-cored, it also has intensity high, and is lightweight.Therefore optical cable strengthening core long service life, product is widely used in the fiber optic cable communications manufacturing without air gap, the excellent properties such as density is large, intensity is high.
