Description
Technical field
The invention belongs to technical field of cables, especially relate to a kind of electric wire sheath material.
Background technology
Electric wire is as the basic industry of national economy, its output value has risen the second of national economy at home, it is the maximum industry after automobile industry, domestic at present have electric wire mortar businesses more than 15000, wherein contains the enterprise that pure cables manufacturing enterprise and pure fiber optic cable manufacture enterprise and optical cable and cable all produce.
Cable industry is especially in optical cable industry, and the sheath material that conventional outdoor cable adopts is polyethylene, and conventional is Low Density Polyethylene, medium-density polyethylene, high density polyethylene(HDPE).In the standard of optical cable and cable industry, require bar none the surface of sheath should rounding smooth, all should without eyesight visible bubble, sand holes and crackle on any transverse section.For when there is below sheath metal level, need to adopt electric approach to carry out the integrity test of sheath to sheath, direct voltage or voltage of alternating current is normally adopted to carry out sheath spark test, minimum value is normally adopted to be the volts DS (in units of KV) of 9 times of jacket thickness values and the volts DS being less than 25KV carries out, as jacket thickness be 2mm time, adopt the volts DS of 2 × 9=18KV to carry out spark test; Or adopt the voltage of alternating current (in units of KV, and being virtual value) of 6 times of jacket thickness values and the voltage of alternating current being less than 15KV carries out, as jacket thickness be 2mm time, adopt the voltage of alternating current of 2 × 6=12KV virtual value to carry out spark test; Can not be punctured by trial voltage, carry out when this tests normally online production, arbitrary section of sheath is all tested, have puncture namely defective; Have when puncturing, the cross section of sheath has usually more eyesight visible bubble, sand holes and crackle; Certainly, the cross section of the sheath do not punctured might not be exactly do not have eyesight visible bubble, sand holes and crackle, and likely also have eyesight visible bubble, sand holes and crackle, only eyesight visible bubble, sand holes and crackle are fewer or not obvious.
In prior art, the method for sheath material granulating has two kinds, and a kind of mode is earnestly, on extruder die head with scraper expecting directly to scrape off, then with the particle that air cooling or water cooling scrape off; Another kind of mode is that the material that cold-extruded goes out normally is cut into particle again with after water cooling.Adopt air-cooled mode time fervent, usual production line is longer, is placed on streamline and cools further after scaling off, and this mode production rate is very fast, during to the streamline end, usually just can pack; And during cold cut, although it is less that production unit can be made to take up room, after granulating, need further drying, therefore, need the long period and spend more electric power.Because plastic pellet is after granulating, normally piles and piles ofly to put together, therefore, no matter cold cut or earnestly, all without the abundant dry plastics particle of stream, at dry weather, sheath particle to meet the requirement that optical cable or cable are produced usually, and idol has punch-through; But in yellow plum weather or moisture larger season; due to the existence of the aqueous vapor of local in sheath material surface and sheath material; cause puncturing of sheath when optical, electrical cable usually can be made to manufacture, cause scrapping of whole cable, cause the increase of cost and unnecessary trouble to cable manufacturer.
Cable manufacturing enterprise is in order to avoid puncturing and the generation of cavitations, normally adopt and come partly to solve for the production of the mode of front carrying out one-level or secondary oven dry at sheath material, one-level or secondary are dried and normally before manufacture plastics are put into dryer, 4 hours are dried in 40 ~ 80 DEG C of temperature ranges, this mode can make the moisture content part of particle surface remove, but can not remove the part aqueous vapor of inside particles.
This phenomenon, can be described as the problem that line cable industry cannot overcome at present, therefore, in industry, as long as there is fairly large cable manufacturer, all wishes to find and make the sheath material that sheath does not puncture or breakdown probability reduces greatly, but regrettably there is no effective terms of settlement at present.
