Description
Technical field
The present invention relates to a kind of energy-conservation, environmental protection, zero pollutes, zero discharge, PE cable is crosslinked, Plastic-sheathed Cable vulcanizes shared unit.Technical background
In cable machinery in the past; The sulfuration of Plastic-sheathed Cable and the cross-linking apparatus of PE cable are private separately, and the Plastic-sheathed Cable sulfuration must be used vulcanizing equipment, and the crosslinked of PE cable must be used cross-linking apparatus; Can not be shared mutually between them, cause the significant wastage on the resource.The fundamental method of company's sulphur equipment of Plastic-sheathed Cable is that boiler produces high steam sulfuration and air pressure salt bath vulcanization, and pore is big in the insulant, and quantity is many, therefore can only produce the low-grade withstand voltage cable that hangs down; The Boiler High Pressure steam vulcanization (cure), construction investment is big, and serious environment pollution, coal per ton will produce 2 tons of carbon dioxide and toxic gas; Be prone to produce carcinogen in the sulfidation, boiler itself is dangerous big, and power consumption is big, and boiler life is short; Must change after several years, maintenance cost is high, is prone to simultaneously produce pollute.The curing medium of air pressure salt bath vulcanization is a nitrite, can be carcinogenic, and hot salt is prone to ejection hurts sb.'s feelings, and salt cleans will consume great amount of time; Manpower and energy, the heating of salt is solid-state liquefy, is that the states of matter variation will consume lot of energy, salt is again conductive materials; Clean eventually in any case and can stay remnants, influence the cable insulation level, steam vulcanization (cure) and salt bath vulcanization all need a large amount of water; The consumption that has promptly increased energy has brought pollution and cable quality low of environment again, and the basic skills of crosslinked cable production is that vertically upright tower is crosslinked with the suspension type long pipeline, the equipment investment costliness; Basic construction investment is very big, and crosslinked cable is used nitrogen, vapor crosslinking; Heat transferred is poor, and thermal capacity is little, and the insulation level of crosslinked cable is all crosslinked less than silicone oil bath.Because its medium of silicone oil bath vulcanization crosslinking is a modified silicon oil, its proportion is the same basically with poly proportion, can not produce sagging eccentric phenomena, therefore needn't invest the expensive upright tower and the construction cost in workshop; Capital expenditure is dwindled greatly, because modified silicon oil transmission heat is fast, under-70 to 400 ℃ of temperature, no states of matter changes; Both there be not heat of gasification (100 ℃ of water of 1 gram become 100 ℃ of steam needs 539 kilocalorie heats, and 1 ℃ of 1 gram water elevated temperature only needs 1 card heat); Also do not have heat of solution (heat of fusion of 1 gram salt is 80 card heats), silicone oil is elevated to crosslinked from normal temperature, and the energy that curing temperature consumed compares steam; Than the little hundred times to tens of salt times, so silicone oil is cross-linking vulcanized, and to have an investment little, high efficiency; The characteristics energy-conservation, that product quality is high are used according to reality; The energy charge of its vulcanization crosslinking only is 1/10th of a Boiler Steam, nitrogen crosslinked 1/15th, plant and equipment investment is the vapor crosslinking sulfuration; Nitrogen crosslinked 1/3rd, though modified silicon oil has above advantage, the antecedent of silicone oil vulcanized rubber still of no use.At present, salt bath vulcanization, the pipeline of steam vulcanization (cure) and cooling pipe all point-blank, length is long; Increased unit span and capital expenditure, because the impossible balance of pressure at two ends, in case unbalance, be easy to the generation personnel and scald; Because unwrapping wire, take-up distance are produced for operation and made troubles more than 60 meters, because cooling pipe is not have the cooling of pressure; Though perhaps band is pressed cooling, pressure is lower than curing tube, and length is short again, can't eliminate internal cause power and foaming.In order to improve curingprocess rate, institute's employing way 1. improves temperature.2. increase vulcanizing agent, promoter.3. growth pipeline.In three kinds of ways, 1 and 2 is all inadvisable, and increase temperature and can make ageing of rubber, mechanical properties decrease, energy consumption increases.Though the 3rd kind of method is desirable, the equipment investment capital expenditure is increased.Summary of the invention
