Abstract
A method for strengthening paper product features that a die set whose shape is same as the shape of the paper product to be srengthened is used to press and heat the both surfaces of the paperboard of the paper product at 200-500 deg.C under 20-40 Kg/sq.cm for 5-60 s.
Description
Technical field
The present invention relates to a kind of paper products intensifying method.
Background technology
After various paper products such as existing carton and picture mosaic made of paper are made, do not improve the feasible method of its intensity, therefore the not high defective of ubiquity intensity has influenced result of use, has limited the scope of application, for improving intensity, the other materials of often having to adopt in the practice, or carry out the compound of multiple material, not only improved cost, wasted resource, but also can cause problem of environmental pollution because of the employing of other materials.
Summary of the invention
For overcoming the existing not high defective of paper products intensity, the utility model provides a kind of paper products to add strong method, this method adopts physical means that paper products are strengthened, under cost seldom, just can obviously improve the intensity of paper products, and can not bring waste and environmental pollution on the resource.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of paper products intensifying method, it adopts the mould of heating to the paper products processing of heating of pressurizeing, and eliminates the fold of each cardboard of paper products, and 90 ° of arc fold bendings of paper products are become the right angle bending.
Because the present invention is to processings of having carried out heating of the paper products of moulding, the paper products after the processing produce following variation: the one, and the surfacing of each cardboard of formation paper products, fold disappearance on the cardboard; The 2nd, the end face of each cardboard particularly each cardboard is in contact with one another with the sheared edge that acts on and all becomes the plane vertical with the cardboard tow sides, interconnect the place and be rectangular shape, eliminate the arc transiting surface and the burr limit that produce because of shearing between sheared edge and the paperboard surface, eliminated the wedge gap that each cardboard place of being in contact with one another causes because of arc transiting surface; The 3rd, original 90 ° of arc fold bendings all become the right angle on the paper products such as carton, these change the load-carrying ability that has greatly improved each cardboard, also greatly changed the action direction of power between each cardboard that constitutes paper products, basically eliminated the oblique active force that very easily causes the paper products bending, greatly improved the intensity of paper products thus, not only improved the result of use of paper products, also expanded the scope of application of paper products, made and to adopt the goods of papery to be adopted paper products under the prior art.According to applicant's preliminary experiment, through the shirt package carton of this intensive treatment, its bearing capacity has improved tens of times, through the papery picture mosaic of this intensive treatment, pieces together and is pinching two angles after good and just can integral body take up, and also can hang up and can not loose.
The specific embodiment
The specific embodiment of the present invention is:
1) by cross cutting and folding, produce the paper products of moulding, carton (for example transporting the box of chick) for the needs ventilation rushes to some passages in cross cutting, for the sticky paper products of needs, can or carry out stickyly in folding process after folding, be to improve bulk strength, and the paper products particularly bearing plate of carton all should be set to vertical panel, for ready-made paper products, can directly enter subsequent step;
2) mould that mates according to the design shape manufacturing of paper products, corresponding to the bending part of paper products, the rib place of its mould is shape at right angles, and corresponding to the place, plane of plane cardboard, mould should be the plane;
3) working pressure machine, for example hydraulic press pressurizes on the cardboard two sides of paper products by mould, and keeps certain hour;
4) in pressurization, paper products are heated, can give mold heated, heat to paper products by mould with preference temperature by electric heating or other modes;
The pressure of described pressurization should be not less than 15kg/cm usually
2, be lower than this pressure and allow, but need the long processing time, influence efficient, consider the cost under efficient and the prior art background, pressure range can be 20-40kg/cm
2, preferred 20-30kg/cm
2, more suitable pressure is 25kg/cm
2About, specifically pressure is for example: 10kg/cm
2, 15kg/cm
2, 18kg/cm
2, 20kg/cm
2, 22kg/cm
2, 23kg/cm
2, 25kg/cm
2, 28kg/cm
2, 30kg/cm
2, 34kg/cm
2, 38kg/cm
2, 40kg/cm
2, 50kg/cm
2, 70kg/cm
2, 90kg/cm
2
Described temperature range of heating (refers to the temperature that paper products reach in the processing procedure, it can be 200 ℃-500 ℃ down together), preferred 350 ℃-400 ℃, the temperature that is lower than these scopes allows, but need the long processing time, or reinforcing degree is limited, for example 120 ℃ of actual temps, 160 ℃, 200 ℃, 230 ℃, 250 ℃, 280 ℃, 300 ℃, 330 ℃, 350 ℃, 370 ℃, 380 ℃, 400 ℃, 430 ℃, 450 ℃, 480 ℃, 500 ℃, maximum temperature should be controlled at the degree that the paper products material is not produced infringement, different paper products can have different maximum temperature restrictions, can determine according to the character of respective material;
Described pressurization processing time of heating can be 5-60 second, for example 5 seconds, 8 seconds, 11 seconds, 15 seconds, 19 seconds, 23 seconds, 25 seconds, 27 seconds, 30 seconds, 32 seconds, 34 seconds, 36 seconds, 38 seconds, 40 seconds, 45 seconds, 50 seconds, 60 seconds, be understandable that, processing time should adapt with the character of pressure and temperature and processed paper products, under certain processing requirements, the prolongation processing time can correspondingly be reduced treatment temperature and pressure;
Because the different in kind of different paper products should be provided with concrete parameter according to the character of concrete paper products in the practice, also can just can find out the rational and effective processing parameter by experiment.Allow to use the parameter that exceeds the above-mentioned parameter scope when needing.
The paper products of so-called moulding are meant operable papery finished product in the present patent application, and this finished product can be the assembling all-in-one-piece, also can be to be used some loose mails by the user.
So-called cardboard is meant the papery flaky material under the arbitrarily concrete shape, usually be plane, also can be the arbitrary surface shape, can be any thickness and any internal structure, can be simple papery, also can be to be that basic unit or other can embody the wherein composite of papery part strength characteristics arbitrarily with the paper material.
So-called right angle folding (or rectangular-shaped) is meant that two parts of turning up (or linking to each other) are vertical mutually, and turning up (or linking to each other), to locate two-part surface vertical mutually, not crooked, arc transiting surface do not occur.
So-called smooth wrinkle and the folding of eliminating outside the designing requirement that be meant, so-called design comprise design on the material and the design on the goods.
So-called end face is the face that connects positive and negative two surfaces of cardboard on the cardboard.
