Description
Technical field
The present invention relates to and a kind ofly peck central tube type optical cable and manufacture method thereof for mouse bite preventing, the anti-bite anti-of anti-unfirmly closing.Use is laid in the area that this optical cable is applicable to mouse trouble especially severe.
Background technology
Be exactly prevent the optical cable after laying in use various muroid and stinging of some birds birds peck invasion and attack for the anti-bite anti-optical cable pecked.Fiber cable laying suffers from heavier area mouse, often can now be bitten and destroyed situation by mouse.For some aerial optical cables, the infringement of birds to optical cable like similar woodpecker also happens occasionally.The mode that optical cable protection against rodents bites in the prior art is divided into physics protection against rodents and chemical protection against rodents two class.Physics protection against rodents is mostly in oversheath, arrange coated double-deck steel band or steel wire, not only material and cost of manufacture expensive, optical cables heavy, and cable is more stiff, lays and safeguards inconvenience.Chemistry protection against rodents refers to that in the oversheath of optical cable, to add expelling mouse agent pungent element by a certain percentage reaches the object that protection against rodents bites.Experiment shows that mouse is more responsive to pungent element, it is effective expelling mouse agent of relatively generally acknowledging in the industry, but because pungent element directly adds in cable jacket, in batch mixing and extrusion, a large amount of penetrating odor can be produced, pollute surrounding air, have a strong impact on producers and normally work, give to make to produce and bring very large inconvenience.
Summary of the invention
Technical matters to be solved by this invention is that the deficiency existed for above-mentioned prior art provides a kind of and anti-bitely anti-ly pecks central tube type optical cable and manufacture method thereof, this cable configuration arranges rationally simple, flexible, cost of manufacture is low, can not only the anti-unfirmly closing of mouse bite preventing, and be convenient to make, do not pollute working environment.
The present invention for the optical cable technology scheme solving the problem adopted is: include central tubular cable core and oversheath, it is characterized in that being coated with nonmetal protection against rodents tensile layer at central tubular cable core, nonmetal protection against rodents tensile layer outer cladding inner sheath, outside inner sheath, metal armor layers is set, metal armor layers outer cladding oversheath, described oversheath comprises oversheath internal layer and oversheath is outer, described oversheath internal layer is chemical protection against rodents layer, and described oversheath skin is hard high-density polyethylene layer.
By such scheme, described inner sheath comprises internal layer and outer jacket, and described internal layer is chemical protection against rodents layer, and described outer jacket is tygon clad.

By such scheme, the outer field monolateral thickness of described oversheath is 0.1 ~ 0.5mm.
By such scheme, when described hard high-density polyethylene layer is part redness, RED sector longitudinally distributes, in straight banded or spiral shape.
By such scheme, described chemical protection against rodents layer is the polythene material layer containing expelling mouse agent, and described expelling mouse agent is pungent element or modification pungent element, and addition is 0.5 ~ 5% by weight.
By such scheme, described nonmetal protection against rodents tensile layer is glass fibre cotton yarn tape or glass fiber yarn clad, and described metal armor layers is vertical Baogang band.
By such scheme, described central tubular cable core comprises center sleeve, be set with in center sleeve fibre ribbon or optical fiber and filling blocks water fine cream.
The manufacture method technical scheme of optical cable of the present invention is:
First make central tubular cable core;
Extrude inner sheath: sleeve pipe is with some tension unwrapping wire, at the uniform velocity through inner sheath mould after coated nonmetal protection against rodents tensile layer (glass fibre cotton yarn tape), outside described nonmetal protection against rodents tensile layer, inner sheath is extruded with sheath extruding machine, it is characterized in that described inner sheath mould is the Double-head mould being provided with spreader, the cable core of coated nonmetal protection against rodents tensile layer is through Double-head mould, extrude inner sheath internal layer containing expelling mouse agent and outer jacket outward, take-up at the nonmetal protection against rodents tensile layer of cable core simultaneously;
Clad metal armor: by the cable of coated inner cladding at the uniform velocity through metal armouring shaping mould, form metal armor layers;
Extrude oversheath: the cable of clad metal armor is at the uniform velocity through oversheath mould, outside described metal armor layers, oversheath is extruded with oversheath extruding machine, described oversheath mould is the Double-head mould being provided with spreader, the cable of clad metal armor, through Double-head mould, extrudes oversheath internal layer containing expelling mouse agent outward with outer at metal armor layers simultaneously.
By such scheme, described Double-head comprises the extruder that extrudes containing expelling mouse agent sheath inner layer material and extrudes the extruder of coated cladding material and finally shaping co-extruding machine head; Described sheath internal layer and outer field material are extruded jointly from same die orifice, inside and outside layer tight bond, outwards to be volatilized diffusion by the outer field coated internal layer expelling mouse agent that cuts off of sheath.
By such scheme, described expelling mouse agent is mixed into heating and melting in protective cover material in proportion in the material extrusion process of extruder, described batch mixing process is below the hopper of protective cover material extruder, expelling mouse agent implanter with screw conveyer is laterally installed, by the mixed volume of the regulable control expelling mouse agent of the screw speed of implanter above feed opening.
The invention has the beneficial effects as follows: 1, adopt the inner/outer sheath of double clad and interior structure of establishing nonmetal protection against rodents layer, armor, physics protection against rodents is combined with chemical protection against rodents mode, form multilayer protection against rodents protective seam, make optical cable possess extremely strong protection against rodents to bite performance, and along with progressively infiltration and the diffusion of internal layer expelling mouse agent outer layers, in addition outer field hard slippery, can make optical cable prevent murine bite destroy performance further strengthened; 2, adopt the effect of hard slippery external sheath layer red color layer in addition, effectively can threaten the stop of birds birds on cable and sting and peck invasion and attack, birds are more difficult when pecking optical cable finds center of effort, even if find center of effort, the hardness of optical cable also can prevent from being pecked stinging; 3, in the internal layer containing expelling mouse agent is coated on by double clad inner/outer sheath, add and adopt man-hour coextrusion mold mode that ectonexine is formed simultaneously, cut off the volatilization of expelling mouse agent in process, avoid the environmental pollution in process; 4, vibrational power flow advantages of simple of the present invention, barrier propterty is strong, and physical strength is high, and cost of manufacture is low, and optical cable is soft, lightweight, is easy to use and lay.Glass fibre cotton yarn tape is positioned between interior oversheath, can as tensile elements, again can as mouse bite preventing material, cost-saving.
