Description
Technical field
The present invention relates to a kind of pulp technology for making paper, be specifically related to the production method of a kind of light grey resisting fatigue paper.
Background technology
People's blank sheet of paper used in everyday, there is the reflection of white full range, eyes there is stimulation, eye is had an impact in near-distance reading by traditional books paper, it can produce near-distance reading platycoria and closely brightness increase the contradiction of pupil contraction regard state, depending on receive during surplus body white light set off by contrast black and distort dispersion viewpoint make to would recognize that depending on colour cast other color backward depending on state and colour require organizational structure adjust meet they correctly regarding effect, this all can promote eyestrain.It is thin that the patent of Patent No. 95111654 discloses a kind of myopic-preventing book, it is proposed that the reflection light of " in different visual environments, visual capacity and degree of fatigue are different " white book printing paper can suppress colour vision function, reduce visual capacity；White reflective light can cause the visual fatigue of maximum while causing high-high brightness contrast, and this fatigue environment easilys lead to myopia.Advocate to use yellow paper to print student's book for this thin.The patent of Patent No. 98110785 also discloses that a kind of myopia thin paper using of book, advocate to use green paper to print book thin, these new books are thin to some extent solves the reflection Xanthophyll cycle colour vision function due to white paper really, reduce visual capacity, the problem being easily caused myopia, but yellow and green reflection optical spectrum are all wider scopes, such as, in the vision of people, yellow, the yellow that particularly purity is higher, it is all colours to be easiest to cause asthenopic color, it often leads to too strong Eye irritation, when display screen operation, yellow is exactly clearly by as one of background that should not use；Green reflecting light spectral range is 530～580nm, including light green, medium green and blackish green, although there being the green case as myopia prevention homework book in the market, but standard spectrum luminous efficiency≤0.9154 of this kind of green (spectral range is 570～580nm), it is impossible to function well as anti-asthenopic effect.And Lycoperdon polymorphum Vitt paper, it solves pupil contradiction with low-light level and regards state, with can reflective white font solve distortion dispersion viewpoint regarding state, also solve the coloured light impact on eye with colourless, and solve, with relatively low contrast, dazzle that high-contrast causes and low-light level reduces the energy consumption that light processes.Therefore, ash paper wrongly written or mispronounced character books can effective relieving eye strain.
Owing to current paper typically uses Plant fiber to produce, and the mode that major part uses the white paper after bleaching to add dyestuff prepares paper, use bleach and dyestuff, environment is caused certain injury, use log to manufacture paper simultaneously, cause the felling of forest, destroy environment.According to traditional processing technology, the primary raw material employed in papermaking is not straw pulp, it is simply that wood pulp, and the social reality problem wherein caused is a lot, and such as environmental pollution is big, production cost is high.This project uses secondary stock waste paper as main production raw material, for alleviating China's paper making raw material resource pressure, improves waste and old resource utilization, reduces production cost, promotes recycling economy socialization, have the most significant realistic meaning.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, it is an object of the invention to provide the production method of a kind of resisting fatigue paper, the paper of output is warm Lycoperdon polymorphum Vitt, saturation is 70-90%, and lightness is 20-45%, can effective fatigue alleviating, production process is little to environmental injury, low cost.
A kind of production method of light grey resisting fatigue paper, it is characterised in that should, including following steps:
(1) waste paper or wheat straw pulper being broken into granularity and is less than below 2mm, slurry concentration is the shredded paper slurry of 5-20%；
(2) being sieved through pressurized screen by the shredded paper obtained slurry, pressure is 2-4MPa, and mesh size is 2-5mm；
(3) using defibrator that shredded paper slurry is carried out fiber separation, the fiber fineness obtained is more than 95%, impurity removal rate more than 92%；
(4) isolated fiber is sized mixing colouring, white carbon black, titanium dioxide, aluminum sulfate, gum rosin are added in fibre stuff, its addition accounts for the percentage by weight of slurry: white carbon black 0.1%-0.5%, titanium dioxide 1-5%, aluminum sulfate 5-10%, gum rosin 1.1-2.5%, mix and blend 30-120 minute, mixing temperature is 30-50 DEG C；
(5) dehydration forming, by mixed slurry drying and dewatering molding, dries temperature and is 80-160 DEG C, and drying time is i.e. to can get resisting fatigue paper in 5-30 minute.
In described step 3, solid is retained by the impurity through separating through flocculation filtration, and residue waste water filters after alkaline chemical precipitation metal ion, then through activated carbon adsorption and quartz sand filtration, then arranges outside waste water.
In described step 5, drying and dewatering uses two-sided drying.
The granularity of described white carbon black is 0.5-5um, and the granularity of described titanium dioxide is 1-10um.
Waste paper or wheat straw is used to manufacture resisting fatigue paper, effectively reduce the felling of forest, reduce cost, use pressurized screen and defibrator to realize the at utmost purification of fiber simultaneously, use white carbon black, titanium dioxide directly to mix with fiber and prepare resisting fatigue paper, it is to avoid the use of bleach, decrease the injury to environment, the light gray simultaneously produced is softer, and resisting fatigue effect is more preferable.Use double dewatering drying technology, improve production efficiency, improve the quality of paper simultaneously.
The invention has the beneficial effects as follows: the production method of a kind of light grey resisting fatigue paper, the paper of output is warm Lycoperdon polymorphum Vitt, and saturation is 70-90%, and lightness is 20-45%, can effective fatigue alleviating, production process is little to environmental injury, low cost.
