Abstract
The present invention discloses a method for producing packing boxes from the wastepaper of waste money. For the present invention, after waste money is crumbled, a proper quantity of urea aldehyde resin adhesives, paraffin emulsifying agents and ammonia chloride curing agents are added in the crumbled waste money; the mixed material is shaped by pressurization in a box-shaped mold, and the mold is heated by the radiation of electromagnetic media. A packing box manufactured by the method has the advantages of firm and durable structure, damp prevention, beautiful appearance, no toxin and no pollution. The packing box can be used as a turnover box in the money printing trade and banking systems and can completely replace a wooden box. The present invention solves the problem that pollution can be generated in treating the wastepaper of waste and worn money. A large quantity of wood can be saved per year, and a great quantity of packing expenses can be saved for countries.
Description
The present invention relates to a kind of method, belong to worn coin scrap treatment technology with bits of waste paper money Production and Packaging case.
In the financial field, the processing of useless residual bank note is an a great problem always.Existing processing method mainly is to adopt comminuting method, and paper scrap is as paper making raw material.But owing to contain multiple metallics in the worn coin paper scrap, and the discharging of waste liquid that the paper pulp subsequent treatment causes, seriously polluted.Particularly along with human civilization advance, environmental protection and sustainable development more and more are subjected to the common concern of the whole society.China is no exception, and along with the increasing of environment protection treating dynamics, some with serious pollution enterprises close in succession such as the little paper mill that many conditions are relatively poor, so bits of waste paper money more becomes history as the processing mode of paper making raw material.Government department has to take out every year substantial contribution, drops into manpower and transports worn coin to outlying district employing flame spray regime with it destruction, and pollution problem can not fundamentally solve, and the long-distance accident potential of escorting is very big.It is reported that the annual useless residual bank note that needs to handle in the whole nation has 20,000 tons approximately, how to make it obtain actively handling effectively, is stranded all the time and scratches industry and relevant government department, and adopt import equipment to handle, equipment investment is very big, and is also unrealistic.Therefore, how the worn coin paper scrap science of carrying out is handled, become the problem that the insider presses for solution.On the other hand, seal paper money, coinage industry in the financial field, to being in great demand of packing case, need millions of every year, and these packing cases adopt wooden case more, wooden case by general requirements calculates, the annual timber that almost needs 1 ten thousand stere owing to be disposable use, causes the resource serious waste, and entreprise cost is bigger, and the substitute of therefore seeking a kind of wooden case receives much attention equally.
The object of the present invention is to provide a kind of method with bits of waste paper money Production and Packaging case, it has solved the handling problem of useless worn coin paper scrap, for printing the substitute that paper money enterprise provides a kind of wooden case, has both reduced environmental pollution, can save a large amount of timber resources again.
The objective of the invention is to realize as follows.
Owing to contain a large amount of celluloses in the bits of waste paper money, contain some metallic elements in addition, since can be used as paper making raw material, as long as manage with shredded paper crumb adhesive treatment, add suitable emulsifying agent (waterproofing agent) and curing agent again, use the die pressure moulding, just can produce satisfactory carton, the said packing case of the present invention just.Therefore basic design of the present invention is crushed to certain particle size with the worn coin paper scrap exactly, handles with suitable adhesive, doses suitable emulsifying agent and curing agent, and material is adopted the mould extrusion forming, finally obtains meeting the packing case of instructions for use.
Adhesive commonly used is a catalure, or is called the Lauxite viscose binder, and the present invention selects the urea formaldehyde resin viscose binder for use.PH value transfers to 7.0-7.5 with sodium hydroxide solution and is advisable.
Emulsifying agent used among the present invention plays waterproof action, therefore claims waterproofing agent again, and it mixes with paraffin, oleic acid, ammoniacal liquor and water.
Curing agent is selected ammonium chloride for use.
Determine that it is key of the present invention that rational material cooperates ratio and production technology.The material fit quality ratio of determining through a large amount of tests is:
Emulsifying agent: paraffin: oleic acid: ammoniacal liquor: water=5-10: 1-3: 1-2: 20-40.
All the fit quality ratio of material is: bits of waste paper money: urea-formaldehyde resin adhesive: emulsifying agent: ammonium chloride=150-300: 10-20: 2-4: 0.1-0.2.
Another key of the present invention is the waterproof problem that how to solve packing case.The waterproofing agent that adds appropriate amount is an effective method, such as using ammonium chloride.Material such as adhesive resin glue mixes the method that adopts high wind to spray in this external production technology with bits of waste paper money, it is even to guarantee that bits of waste paper money mixes glue, worn coin approximately mixed stirring by 1: 0.2 with the glue mist in mixed glue space, and suitably heated and enter press die after making its moisture content of about 10% of scattering and disappearing.
In order to enhance productivity, pressurization is carried out with the high frequency electromagnetic radiation heating simultaneously with mould in the moulding process.Shortened molding time, it can be accomplished scale production.
The production method of the said packing case of the present invention comprises the steps:
A, the coin that will give up are ground into chip;
B, make urea-formaldehyde resin adhesive, emulsifying agent, ammonium chloride even with following mixed, mass ratio is: 10-20: 2-4: 0.1-0.2 prepares stand-by;
C, the mixture of urea-formaldehyde resin adhesive, emulsifying agent, ammonium chloride is mixed with bits of waste paper money under powerful wind sprays, stir simultaneously, the mixing of materials mass ratio is:
Bits of waste paper money: urea-formaldehyde resin adhesive: emulsifying agent: ammonium chloride=150-300: 10-20: 2-4: 0.1-0.2.
D, mixed material drop in the box-shaped mould, forming under the pressure, and high frequency electromagnetic radiation heating 2-3 minute, 80 ℃-140 ℃ of temperature controls keep-uped pressure 2-5 minute, and depanning gets finished product.
The packing case that the present invention produced detects through authoritative department, and every index all can reach designing requirement, adorns 40 kilograms in the product, highly freely fall nothing breakage, the nothing breakage down of 30KN pressure from 1 meter, moistureproof and non-deformability conforms to quality requirements, soak 72 hours indeformable, nontoxic, pollution-free.
The obtained technological progress of the present invention is: (1) has solved the pollution problem of worn coin when handling; (2) reduced the input cost of waste paper coin processing mode; (3) eliminated accident potential in the in the past useless coin processing procedure; (4) the waste product packing case is recyclable produces again; (5) can save the timber resources of a large amount of preciousnesses; (6) with " paper " Dai Mu, entreprise cost reduces.
