Abstract
The invention belongs to the technical field of cable kits, particularly relating to a production method for a double-layer co-extrusion wire. The invention discloses the production method for the double-layer co-extrusion wire. The production method is characterized by comprising the following step of A, preparing raw materials; B, putting PVC (Poly Vinyl Chloride) particles with different densities into two plastic extruding machines, and putting a conductor into the center of a mold; C, performing extrusion molding on two kinds of PVC sticky fluids with different densities through the mold after the two kinds of PVC sticky fluids with different densities simultaneously enter the mold; and cooling and coagulating the extruded PVC sticky fluids into solid, and obtaining a finished product; and D, performing a spark experiment on the finished product, and packaging and warehousing the finished product. According to the production process of the production method, the two plastic extruding machines simultaneously extrude plastic in two different colors and different types; the conventional performance of the wire is not influenced after the finished product is produced, and the wire is more aesthetic than the conventional wire; and moreover, the cost is saved.
Description
Technical field
The invention belongs to cable apparatus technical field, relate in particular to a kind of double-layer coextrusion line production method.
Background technology
Along with the development of society, people's growth in the living standard also is more and more higher for the requirement of Electrical Safety.At present, the application of electric wire also is more and more wider, and the cable of electricity consumption generally all is single-core line, mainly is that the center is provided with a conductor, and then the outer wrap at conductor has one deck plastic insulating layer.And present used plastic insulating layer generally all is low-density plastics.This type of plastic insulating layer material is better, and high temperature strength is better, so the plastic insulating layer of single line cable all adopts low-density plastics, so that cost is higher, has caused the waste of resource.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of double-layer coextrusion line production method is provided, its technical scheme is as follows:
A kind of double-layer coextrusion line production method is characterized in that step is as follows:
A: raw material are prepared: PVC particle and the conductor of choosing two kinds of different densities;
B: the PVC particle of different densities is put in two plastic extruding machines, and conductor enters into the mold center place; Simultaneously two plastic extruding machines are heated to so that the PVC particle by the solid-state viscous state that becomes, under the thrust of plastic extruding machine, is pushed the PVC rheid to head, prepare to enter mould;
C: after the PVC rheid of two kinds of different densities enters mould simultaneously, wherein highdensity PVC rheid is wrapped in the outside of conductor, low-density PVC rheid then is the outside that is wrapped in highdensity PVC rheid, so that the PVC rheid of different densities passes through mould and extrusion molding; PVC rheid after extruding condenses into solid state through cooling, obtains finished product;
D: finished product is carried out packing warehouse-in after the spark experiment.
The double-layer coextrusion line, full name polyvinyl chloride insulation is without the general service cable of sheath, and single core has another name called the permanent wiring unjacked cable.This line general service cable lays or embeds pipeline or wire casing along the surface.Be not suitable for and lay onboard or in the channel plastics let out road of cover plate (have except).Being applicable to illumination apparatus and indoor electric appliance has laying of protection as fixing, and the alternating voltage of equipment is generally below the 1000V, or direct voltage is generally below the 750V over the ground.
What the mould among the present invention adopted is hierarchy, the center is for placing conductor, can supply the moving endothecium structure of high-density plastic's laminar flow and outwards be provided with a circle around the center, can be for the moving layer structure of low density plastics's laminar flow and outwards be provided with a circle at endothecium structure.
The double-layer coextrusion line intersects at common single-core line, on manufacture craft, because there is two layers of plastic to extrude simultaneously, so on equipment, Duo a plastic extruding machine main frame than common single-core line.When extruding, can select the plastics of different model and color.Two plastic extruding machines are extruded two kinds of different colours simultaneously, and the plastics of different model not only do not affect the original performance of this line behind the finished product, and more attractive in appearance than original line, and main is to have saved cost.Be under the cost of low-density material entirely originally, changing to internal layer is high-density material, and only the very thin one deck in outside is the low-density material, so cost descends greatly, and does not affect its serviceability, plays an inexpensive effect.
Embodiment
The below specifies embodiment:
A kind of double-layer coextrusion line production method, step is as follows:
A: raw material are prepared: choose density and be 1.40 and 1.60 PVC particle and copper wire;
B: be density that 1.40 and 1.60 PVC particle is put in two plastic extruding machines, copper wire enters into the mold center place; Simultaneously two plastic extruding machines are heated to so that the PVC particle by the solid-state viscous state that becomes, under the thrust of plastic extruding machine, is pushed the PVC rheid to head, prepare to enter mould;
C: density is after 1.40 and 1.60 PVC rheid enters mould simultaneously, wherein density is the outside that 1.60 PVC rheid is wrapped in seal wire, density is that 1.40 PVC rheid then is to be wrapped in the outside that density is 1.60 PVC rheid, so that density is that 1.40 and 1.60 PVC rheid is through mould and extrusion molding; PVC rheid after extruding condenses into solid state through cooling, obtains finished product;
D: finished product is carried out packing warehouse-in after the spark experiment.
The double-layer coextrusion line intersects at common single-core line, on manufacture craft, because there is two layers of plastic to extrude simultaneously, so on equipment, Duo a plastic extruding machine main frame than common single-core line.When extruding, can select the plastics of different model and color.Two plastic extruding machines are extruded two kinds of different colours simultaneously, and the plastics of different model not only do not affect the original performance of this line behind the finished product, and more attractive in appearance than original line, and main is to have saved cost.Be under the cost of low-density material entirely originally, changing to internal layer is high-density material, and only the very thin one deck in outside is the low-density material, so cost descends greatly, and does not affect its serviceability, plays an inexpensive effect.
