Description
Technical field
The present invention relates to a kind of discarded object recycling technology, particularly a kind of recycling technology and device thereof of chromatic steel sandwich plate.
Background technology
Polystyrene foam plastics light weight, intensity height have performances such as good heat insulation, sound insulation, buffering, are the preferred packing materials of present sandwich color steel.After the violent earthquake of Wenchuan, a large amount of movable plank house of being built by the sandwich color steel plate is thickly dotted soon to have spread all over whole disaster area, and along with constantly building up of permanent housing, most board houses all will withdraw from people's life in the time in 2～3 years.And the useful life of chromatic steel sandwich plate just 2～3 years just will face discardedly afterwards, and for the discarded board house of Sichuan post-disaster reconstruction, this part quantity of chromatic steel sandwich plate is surprisingly tangible huge.
As the movable plank house that builds up by chromatic steel sandwich plate because its intrinsic characteristic, after dismounting, almost can't utilize again, so as these huge discarded living areas, except the house refuse that in people's inhabitation process, constantly produces, maximum rubbish has but become house that people once lived, a thorny difficult problem that has just become us to have to face to the processing of these rubbish, in fact with regard to As-Is, not too optimistic, in the process of construction of movable plank house, remaining tailing when countless piles and piles of movable plank houses having occurred and building, these tailings are peelled off the highway both sides that is deposited at random behind the sheet iron by local villager, and foam beads in small, broken bits is opened to kick up later at vehicle and flown away farther field again.
At present, landfill is to handle the most frequently used practice of house refuse, we have not had more effective mode to poly processing except landfill yet, behind the landfill, microorganism and moistening environment but no longer cut any ice to plastics such as polyethylene, have only sunlight to shine them and begin just on one's body to see gradually that light disintegrates.
Not hard to imagine, as if being nuzzled, they lose in the soil of sunlight, and what kind of form they can be.Scientist can't determine finally how long a polybag is thoroughly needed by nature digestion, perhaps 400 years, perhaps want more than one thousand years, and destroy the venting capability of soil, the water-holding capacity of reduction soil simultaneously.
And use the processing mode of burning just more inadvisable, these plastic products can produce multiple harmful organic product when combustion degradation, such as dioxin, chloride, sulfide etc., these noxious materials have just repeated no more ecological and human body and vegeto-animal harm.
