Description
Technical field
The present invention relates to a kind of manufacture method of refrigerator, relate in particular to a kind of door body of refrigerating plant or the preparation method of casing and this body or casing.
Background technology
Refrigerator is widely used a kind of household electrical appliance, along with the learies of household electrical appliance electronic product is increasing, the processing of waste household appliances is also become to the focus that people pay close attention to gradually, and in the processing of many discarded household appliances electronic products, the products such as discarded refrigerator (refrigerator) increase its recovery difficult owing to containing insulating foam layer.It is adopted to non-normal processing, the one, the leakage (refrigerator products before 2000) that easily produces freon, destroys the ozone layer in atmosphere; The 2nd, incinerating method serious environment pollution; The 3rd, the ABS plastic plate of steel plate, plastic plate (mostly being ABS, PC etc.) and the liner of insulating foam layer and refrigerator shell is bonding closely, and separation difficulty causes great difficulty to the recycling of material.General processing method can only be to remove after compressor at present.Men Tiyu refrigerator body is separated, and so hand getting is reclaimed by the method for cracking and sorting.But the particle diameter that is crushed to 20-30mm left and right can expend the larger energy, equipment manufacturing cost and maintenance cost are all very high, and comparatively expensive, separating effect is also undesirable.Broken apart steel plate out and the recovery of plastics are caused to difficulty, and residual polyurethane also can discharge sub-fraction CFC, and then welding.
Polyurethane is thermosetting resin, and after sclerosis, molecule is ternary network structure, is difficult to dissolve or melt, so be difficult for recycling, its waste product conventionally can only burn and bury processing.Some informal processors and underground workshop adopt directly and peel off, and take off panel steel or plastics etc., waste time and energy.And, in polyurethane foam, containing fluorine Lyons, can not discharge according to state's laws regulation, must be reclaimed.Fluorine Lyons can be reclaimed with charcoal absorption, and recovery method is in obturator, heat insulation layer hard polyurethane foam to be pulverized, and is collected, compresses, liquefied in the fluorine Lyons of disengaging.Then in the useless treating apparatus of danger, carry out environmental protection burning or the disposal of other environmental protectionization.Wrongful disposal causes the direct leakage of freon, serious environment pollution.And manual poor efficiency, secondary pollution of disassembling be serious etc., problem becomes increasingly conspicuous.The high-quality that realizes polyurethane foam recycles, and reaches economical, efficient, is the not little challenge running in plastics recovery process.Thereby, must seek high efficiency refrigerator disassembling method, meet to carry out the high-efficiency resource recycling of material, to disassemble down the material that recycling requires, such as steel plate, inner bag ABS/PC material waits further to recycle.
