Abstract
The invention discloses a manufacturing method of PE fiber for a central tube type cable, and is characterized in that aramid fiber is replaced by the PE fiber, and an outer jacket part subjected to heat processing is separated through a process of coating a layer of a polyimide film or a polyimide insulation tape, so that the temperature cannot be higher than the maximum temperature limit of a PE fiber yarn in a manufacturing process. According to the method, advantages of an ultra-high molecular PE fiber yarn are utilized to reinforce using performance of the cable and avoid damage to the performance of the ultra-high molecular PE fiber yarn in a high-temperature production process.
Description
Technical field:
The present invention relates to the communications optical cable technical field, be specially the method field of manufacturing of PE fiber for central tube type optical cable.
Background technology:
It has unique combination property UHMWPE fiber (being again super high strength PE fiber), and its density is less than 1, can float on water, is one of fiber that current intensity is the highest, and specific strength can reach 15 times of high-quality steel, and modulus is also very high, is only second to extraordinary carbon fiber.Breaking elongation is high than other special fibre, and work to break is large.In addition, this fiber also has UV resistant radiation, resistance to chemical attack, specific energy absorption is high, specific inductive capacity is low, the Electromgnetically-transparent rate is high, the low excellent properties such as outstanding shock resistance, anti-cutting that reach of friction factor, be one of large tec fiber in the world today three (carbon fiber, aramid fiber, high-strength high-modulus polyethylene fiber), it is a kind of fiber with height-oriented extended-chain configuration.
Therefore it has very high axial specific tensile strength and rigidity, high specific modulus, outstanding shock resistance and anti-cutting toughness, good numerous excellent specific properties such as chemical stability such as low temperature resistant, wear-resisting and UV resistant, also bringing into play very important effect in fields such as security protection, aerospace, Aeronautics and Astronautics, in addition, this fiber also has broad application prospects at automobile making, shipbuilding, physical culture, hawser, navigation, shock resistance and anti-seismic material and other high-performance light prepare composite.
But superhigh molecular weight polyethylene material is relatively feared for high temperature, ultra-high molecular weight polyethylene is because molecular weight is huge, and crystallinity is high, and its dissolving need be carried out at high temperature, under long-time.And, under the condition of high temperature, thermo-oxidative pyrolysis easily occurs in ultra-high molecular weight polyethylene.Be generally used for the antioxidant 1010 (a kind of polynary hindered phenol type antioxidant) of common molecular weight polyethylene, inadequate to ultra-high molecular weight polyethylene antioxidant effect when dissolving, for a long time under 170 ℃ of temperature environments, the viscosity of super high molecular polyethylene solution has the phenomenon of obvious decline, and prepared polyethylene fibre intensity descends greatly.Therefore, although this material has obtained using widely in fields such as new building materials, but in the electronics and information industry field, for example in the optical cable product, to this high performance PE fibrous material, use less, because optical cable will be through the outer material melt stage of protecting of several Baidu, so its technology can't obtain breakthrough always in manufacture process.
Summary of the invention:
The object of the invention is to overcome the deficiencies in the prior art, the manufacture method of PE fiber for central tube type optical cable is provided.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: with the PE fiber, replace aramid fiber, by wrapping up in the technique of applying one deck Kapton or polyimide heat insulating belt, to stand hot worked oversheath position and separate, thereby realize the maximum temperature that temperature can not be born higher than the PE silvalin in manufacturing process.
Optionally, the cable outer diameter of described method manufacture is about the 8.6mm left and right, and it is 1KN that tension force is used in maximum permission.
Optionally, the described technique of applying one deck Kapton or polyimide heat insulating belt of wrapping up in, used vertical packet mode it to be wrapped up in deposited.
Optionally, described cover is moulded process using high-modulus, high strength, low shrinkable polymer.
Optionally, the optical cable product structure produced comprises oversheath, Kapton, PE silvalin, loose sleeve pipe, optical fiber, fine cream.
The present invention contrasts prior art following beneficial effect: utilize the plurality of advantages of supra polymer PE fiber yarn to strengthen the usability of optical cable, and avoid the injury to supra polymer PE fiber yarn performance in the high temperature production link.
The accompanying drawing explanation:
