Description

Use multiplexing office paper equipment of laser

Technical Field

The invention belongs to the technical field of office paper processing, and particularly relates to a laser-based office paper multiplexing device.

Background

The office paper belongs to disposable consumable materials, the value of the office paper depends on printed image-text information, the office paper with image-text marks does not have the function and the value of reuse any more, the office paper belongs to idle articles or waste, and for the office paper with important image-text marks and other information, the processing mode can be divided into that special sealing protection is adopted for preventing information leakage or electronic backup is carried out through scanning and photographing modes.

The common office paper can be broken and discarded after being used, the paper product belongs to solid garbage, the treatment method does not need to bury or burn, the garbage treatment by burying is a garbage treatment mode with long history, high popularization rate and low operation cost, but is also a mode with the most waste, the most pollution and the longest treatment period, the method depends on natural decomposition, biological action and other means, various pollutants which are not decomposed, such as heavy metal and chemical preparations permeate into soil, permeate into underground water resources along with rainwater, drift away along with wind, some pollutants are obtained by plant crops or livestock, water, air, food and three elements for human existence are all polluted, and the paper product has harmfulness to the ecological environment.

Although the waste paper can be used for generating electricity and heating, the waste paper can be completely combusted, the combustion heat efficiency is low, and beneficial economic benefits cannot be generated, and chemical substances released by office paper in the combustion process generate new pollutants in high-temperature combustion, so that the method not only wastes resources, but also discharges pollutants.

And office paper which can be effectively recycled and reused to obtain value only accounts for a very small part of the total resource, so that the ecological environment is damaged and the resources are wasted by any treatment mode.

The modern paper making technology and the production process of recycled paper are fundamentally the traditional paper making mode, the common points of the production processes are that raw materials are crushed, rinsed, pulped, made into paper and the like, wherein water is used as a main production medium for production and processing, particularly, various pollutants such as resin, cellulose, printing ink, coloring agent, heavy metal and the like in rinsing production links are discharged after treatment to cause pollution damage and resource loss, and even in the environment-friendly and famous recycled paper production process, the parameters such as color, performance and the like of the produced finished paper cannot reach the structural property, the flexibility and the wear resistance of original ecological paper pulp fiber, and the paper pulverization phenomenon exists, and the paper performance can only reach the use requirement by adding various chemical preparations to improve the paper performance so as to approach the parameters of the original ecological paper pulp.

In the existing papermaking technology:

1. japanese light corporation has developed an office paper recycling system, the valley system, developed by a technical engineer named valley and named under its name, the technology used by the valley system is a thermochemical principle, a chemical agent capable of chemically reacting with a printing and dyeing material is applied to a copy paper printed with pictures and texts, a heating process is required to accelerate reaction time and improve working efficiency, when the chemical agent reacts with a marking component, heat is generated, the marking is washed off from the copy paper, and then the copy paper is washed, cleaned and dried, and the dried copy paper is reused. However, the paper produced by the technology has chemical substance residues, the process flow has high application risk, and an operator needs to have strict operation skills and operation environment, because the process technology is a wet treatment mode, chemical agents and mixed solution are easy to volatilize and generate air pollution and pungent smell, and the generated waste liquid cannot be safely discharged, so the technology is not popularized, but the application idea is a new promotion for the environment-friendly technology of office paper.

2. A recycled paper manufacturing machine applied to office environments, which uses a Dry Fiber Technology (Dry Fiber Technology) Technology, is developed by japanese fine epson and can manufacture recycled paper without using a large amount of water; after the waste paper is decomposed, other binders can be added to produce paper with different colors and fragrances, and the size and thickness of the paper can be determined according to requirements. Because the regeneration process should mince waste paper into paper fiber, can be regarded as the treatment mode of smashing confidential file, the paper-making process has 3 main steps: firstly, the waste paper is changed into strip-shaped, thin and cotton-like paper fibers; the second step is coagulation, in which substances are added to modify the properties of the paper, such as coloration, etc.; the third step is forming, and the paper fiber is pressed to generate new paper; as a creative environment-friendly recycled paper device, the design concept of 'paper Lab' is advanced, but the technical process is that the raw paper is crushed as a production process, the main component of the office paper is fiber, whether the performance of the office paper is excellent or not depends on parameters such as 'stiffness', 'tenacity', 'compactness', 'tensile resistance' and the like, the performance parameters are affected by the advantages and disadvantages of the paper fiber, if the raw paper which is finished paper is crushed into fiber raw material again, the paper fiber structure generated by the fiber raw material is damaged again, the quality of the finished paper produced in this way has defects, and in order to make up for the product quality defects of the finished paper, a chemical preparation is added in the production process for product improvement for enhancing various performance mechanical parameters of the finished paper, the visual effect of finished paper is improved by using a whitening agent, dyes forming images and texts on original office paper are removed by using an ink remover, and various chemical agents such as a flavoring agent, a coloring agent and a brightening agent are added according to use requirements, and the chemical agents are free of components harmful to the environment and human bodies, so that the minimum use amount and non-main process consumption resources are realized for the use of water resources, the water can be reused, the process for reducing the waste and consumption of water resources is advanced, but the paper can be produced only by using water, and through the consumption and natural volatilization of the production process, the water consumption is reduced as far as possible compared with the production process, the waterless production can be realized, and only a certain amount of raw paper can be produced, and the production can not be carried out at any time.

3. The invention patent of domestic publication No. CN104861764B provides a technology for removing laser printed or copied writing on the surface of paper, which is mainly aimed at removing the writing on the surface of paper after printing or copying by laser printer and laser copier. The method comprises the preparation of a removing solution and a removing method, wherein the removing solution is prepared from hydrofluoric acid, a self-setting denture base polymer (also called denture base water) and water (tap water or distilled water), and the proportion of the removing solution is fixed in a certain range. The removal method is a method of soaking or using mechanical vibration such as ultrasonic wave simultaneously with soaking. The handwriting removing method is matched with the removing solution, and the handwriting printed or copied on the surface of the paper by laser can be completely removed by a chemical dissolving method.

The problem of environmental protection caused by discharge is solved by using a chemical preparation mixed solution, and the problems of instability and shelf life of the chemical preparation cannot be solved properly; the method uses mechanical vibration modes such as ultrasonic waves and the like to carry out accelerated reaction, relates to the addition of other equipment, uses fixed sites, has various specification designs and can not be suitable for all environments under the use conditions; the plastic coating machine is required to be used for leveling processing, otherwise, the normal use is influenced by the unevenness of the material; and chemical residues and water resources are used. The use flow is complicated and complicated, and the problems of chemistry, electrical equipment operation, site planning, personnel training operation, environmental protection emission and the like are involved.
