Description
Technical field
Invention belongs to polymeric material field, especially belongs to a kind of city and industrial waste wooden waste of utilizing and manufactures the friendly polymeric material field of ecosystem environment.
background technology
Present entire society has produced a large amount of wooden rubbish and cannot process in house finishing, resettlement, the waste and old furniture renewal process of resident; The Real estate craze of China, produces a large amount of wooden building wood wastes material---generations of these waste materials too, and environment has been brought to very large pressure.According to measuring and calculating, every 5 to 8 years, many building materials furniture items just entered the phase of eliminating.Human consumer, start to carry out in secondary decoration, these original building materials furniture items have just become the rubbish offending the eye most.At present domesticly not yet building material industry is put into effect and the household electrical appliances similar policy of exchanging old for new, as rubbish one, has been abandoned it more than waste and old building materials furniture item.But does not receive the suspicion occupation of land side collecting scrap, make a gift to someone that nobody want, renovation is not worthed, also inadequacy abandons also improperly, is also likely imposed a fine.In a word, waste and old building materials furniture has become a need problem to be processed in municipal wastes.
Now, waste and old former wooden furniture has producer to reclaim, and does solid wood granule sheet material; PVC plate, aluminium alloy somebody purchase; Compoiste wood floor is more with all not having.Waste and old furniture is exactly to work as refuse treatment, and refuse tip, incity is also inaccurate, must move the refuse landfill in suburb to, can not be mixed in one with domestic refuse.The people who tips rubbish also will pay handling to refuse tip.Not only do not sell money, process and also will spend a lot of money.In addition, there is a lot of glue containing formaldehyde the timber floor of non-solid wood the inside, and producer reclaims again also will put glue after processing, will cause like this environmental protection not up to standard.Producer is if accomplish up to standardly, and processing costs is also higher than using green lumber, in pricing, does not calculate.---the high cost that waste and old furniture is processed technically causes being difficult to use in decoration industry.
The woodwork cyclic utilization rates such as the furniture, sheet material of China are extremely low, and most of waste and old wood just abandons as building materials rubbish after using once, and that can get back to production reprocessing process only accounts for only a few.Tracing it to its cause, is that the production technique of enterprise is not originated this as important source material.Many business peoples think with current technique, also be difficult to melt down reprocessing by these timeworn furniture, old timber are capable, dismounting, cutting, go-no-go etc. technique all needs to expend a large amount of manpower financial capacities, uses log to process and can save lower above-mentioned cost.
It is reported, it can be plank by pulverizing post-treatment that these timeworn furniture have 30% left and right, 30% nonuseable part will be as industrial fuel for boiler combustion, boiler in the present city again overwhelming majority is transformed into thermo oil boiler, these can, with the furniture material of fuel, become again reluctant municipal wastes originally substantially.
Many city inhabitants want house carefully to fit up, but have asked about many places, and originally pretty good timeworn furniture and once visited place plate in room, is exactly that no one reclaims.Moreover, when Yu decoration company signs a contract, also additionally having added one: need to fit up the refuse collection expense that owner bears hundreds of units---many urban house persons of repairing have run into similar situation, and furniture rubbish has become an environmental problem that needs are faced.
Furniture manufacture factory, those wood furniture manufactories especially, the equal less than 70% of material use efficiency, all can leave over more than 30% tailing, and these tailing major parts need to be worked as refuse treatment.
Waste and old wood furniture in the waste material that wooden furniture manufactory leaves over and city is different because of material source, and composition is big difference especially, and this characteristic is utilized these solid waste to bring technical difficulty; Also have a problem to be exactly, the formaldehyde content of these materials is different, major part all likely exceed standard (wood-based plate manufacture and the furniture manufactured with wood-based plate because of the tightness of edge sealing technology good, can guarantee that formaldehyde parcel wherein can not discharge, now because these material requires are smashed re-using, these formaldehyde will discharge), remove these formaldehyde technically and in human cost, be all difficult to meet its benefit performance.
The annual waste or used plastics amount producing of China is 5,000,000 tons of left and right, because plastics have corrosion-resistant, not labile characteristic, and its this characteristic and weight is little, volume is large in rubbish, determined its unsuitable landfill of ultimate disposal, need recycling, to reach plastics resource utilization object, so existing waste or used plastics finished particle is manufactured finished product supply now.But, now when utilizing waste or used plastics, difference because of plastics source and kind, in to reuse of waste plastics process, be easy to produce a problem, if exactly the manufacture temperature in the process of application waste or used plastics particle reach one regularly will burned goods, the fragility of finished product increases, and has a strong impact on intensity and the wearing quality of finished product.---this is the technical bottleneck that needs solution in reuse of waste plastics.
Therefore, be necessary to invent and a kind ofly can fully utilize the waste and old furniture in city, and Furniture Manufacturing Enterprise waste material, and building wooden waste is to realize the technology of furniture garbage as resource object.---realize this target, should be in conjunction with utilizing waste or used plastics technology, the technical issues that need to address of the present invention especially.
