Description
Technical field
The invention belongs to and a kind ofly change solid waste into useful field (B09B 3/00), especially belong to a kind of and utilize wooden waste manufacture in upholstery for the reclamation of solid wastes field of the cave dish of agricultural cultivation.
Background technology
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.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.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.
Current domestic not yet building material industry appearance and the household electrical appliances similar policy of exchanging old for new, has abandoned it as rubbish one 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.
Why does is this? this is because now, and the waste and old building materials man of log has producer and reclaims, and does solid wood granule sheet material, and PVC plate, aluminium alloy somebody want, and 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 the timber floor of non-solid wood the inside, and producer reclaims again also will put glue after processing, will cause environmental protection to be difficult to so 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, 70% 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 added one, refuse collection takes, and hundreds of unit.Though be old, timber floor is also all pretty good, how just nobody want? " many urban house persons of repairing have run into similar situation, the environmental problem that furniture rubbish and needs are faced.
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 on manpower, be all difficult to reach benefit performance.
In sum, the wooden solid waste in city has very big development and utilization to be worth now, and waste material source is also at increase year after year.
No matter be flowers or vegetables, hole plate seedling growth is a most basic change of modern horticultural, for quick and production in enormous quantities provide assurance.Cave dish has become the advantage that cave dish seedling is used in batch production: save seed consumption, reduce production costs; Emerge neat, keep the consistence of plant seedling growth; Can with various manually and seeding plough support the use, be convenient to centralized management, increase work efficiency; During transplanting, do not damage root system, slow seedling is rapid, and surviving rate is high.
The manufactured materials of cave dish mainly contains polystyrene polyphenyl vacuolar membrane; Ornamental plant is grown seedlings and generally uses polystyrene dish, and grow seedlings of vegetable can be used polyphenyl vacuolar membrane dish.The cave dish that these materials are made generally can reuse, but the cave of this recycling dish is also faced with two problems: the one, and because of recycling, may sterilize and sternly can not cause the root rot of seedling; The 2nd, while transplanting, need to remove cave dish, and need strict sterilization while reusing, current labor cost rises so fast, remove with the cost of labor of sterilization cave dish with newly buy cave dish and use that difference is little; The cave dish that these can not be degraded, finally also can bring burden to environment---these characteristics are that large-scale application disposable degradable cave dish has been established market value basis.
In prior art, there are whole use agricultural crop straws, paper to manufacture disposable cave dish, but this class cave dish also has a shortcoming, because adhesive formulation and major ingredient reason are easy to cause cave dish, also do not complete transplanting operation, cave dish is just broken loose, finally affects the surviving rate of transplanted seedling.Some degredation plastic cave dish goods, although can meet the service requirements of agriculture cave dish completely, also faces the cost that a major issue is exactly current this degradable plastics very high, has also limited the extensive use of this cave dish.The source that is exactly in addition waste paper is far from wooden waste so extensively with low cost.
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 manufactures the technology of agricultural cultivation cave dish, to realize wooden waste garbage as resource object.
