Description
Technical field
The present invention relates to resource reutilization technical field, be specifically related to a kind of regeneration plastic-aluminum composite article environmental protection separating technology.
Background technology
Aluminium scrap moulds goods through process, can reclaim aluminium and plastics, and the aluminium of recovery and plastics directly or through modified can be applied to decoration, finishing and packaging etc., and application is more and more extensive, has higher recovery value.Reduce gradually in resource, under overall situation that price increases gradually, if can be recycled, will there is important economic worth and energy-saving and emission-reduction meaning.
At present, plastic-aluminum separating method is common acid-soluble or the molten partition method of alkali, weak acid multi_layer extraction method and demixing of solvents partition method etc.Utilize aluminium can be dissolved in the principle of soda acid, use acid-soluble or that alkali is molten method that the aluminium in material is dissolved, thus recycled plastic, and then aluminum bearing waste is made aluminium polychloride or aluminum sulfate.This acid-soluble or molten partition method of alkali has and reclaims halfway shortcoming.
In addition, utilize organic monoacid molecule such as acetic acid, formic acid etc. can impermeable plasties layer, so dissolve each layer of bonding aluminium oxide and the characteristic of pure aluminum can not be dissolved, by the aluminium in packaging material with plastics are complete is respectively separated.This weak acid multi_layer extraction method has the shortcoming that the reaction time is long, separative efficiency is low.In addition, plastics are utilized by the character of organic solvent as the swelling such as toluene, chloroform, with an organic solvent to make plastics swelling, peeled off from plastic-aluminum sheet by aluminium, then recycle respectively.This demixing of solvents partition method has the shortcoming that solvent consumption is large, toxicity is large, cost is high.
Plastic-aluminum separating agent as a kind of in Chinese patent and preparation method thereof (CN201010596985.0) application number: CN201010596985.0, employing be demixing of solvents partition method; For another example a kind of plastic-aluminum separating agent of Chinese patent and plastic-aluminum separating method (CN101165084), be also adopt demixing of solvents partition method.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of is separated thoroughly, can improve the regeneration plastic-aluminum composite article environmental protection separating technology of resource utilization.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of regeneration plastic-aluminum composite article environmental protection separating technology, comprises following processing step,
1) purchase sorting: from the regeneration plastic-aluminum goods (as plastic-aluminum cable, aluminum-plastic composite membrane, aluminium plastic composite packaging paper etc.) of various places purchase different colours, specification, by manual removal, after extracting the impurity elimination of copper core, plastic-aluminum goods are stacked neat by unification;
2) be separated first: put into high speed disintegrator by unified for the regeneration plastic-aluminum goods after impurity elimination, carry out fragmentation, be processed into the plastic-aluminum block of block specification;
3) secondary separation: the reactor block plastic-aluminum being transported to semitight by conveyer belt, pass into and be steam heated to 100-150 DEG C, the temperature characterisitic different according to plastic-aluminum, within 30-120 minute, make the aluminium plastic material be tightly combined with each other, be separated gradually, obtain purity higher aluminum and mould parting material;
4) aluminum-plastic separation material is put into high-speed grinder to grind, cross 80-150 mesh sieve, then the aluminum-plastic separation material of powdery is extruded graininess plastic-aluminum composite material through extruder;
5) be separated for three times: graininess plastic-aluminum composite material is placed in hydrolytic tank by conveyer immediately, in hydrolytic tank, injects normal-temperature water, utilize the mobility of stirring wheel and water, granular plastic-aluminum composite material is cooled rapidly, natural separation after expanding with heat and contract with cold, plastics float, and aluminium powder sinks;
6) plastic grain of drift and the aluminium powder of sinking in collection, obtain plastic grain and aluminium powder that purity reaches 99%;
7) by plastic grain and aluminium powder airing (oven dry) respectively, after drying, unitizing is put in storage, and aluminium powder is for the preparation of aluminum products such as aluminium bars, and recycled plastic granules is for the preparation of plastic products such as battery jars.
The invention has the beneficial effects as follows: environmental protection of the present invention, energy-conservation, operating process is simple, and separative efficiency is high, quality is purer, the aluminium obtained and plastics all have higher recovery value, directly or through modified can be applied to every field, have important economic worth and energy-saving and emission-reduction meaning.
Accompanying drawing explanation
Fig. 1 is present invention process FB(flow block).
