Abstract
The invention discloses a method for preparing environmental-friendly cardboard paper by deinked sludge of wastepaper. The method provided by the invention comprises the following steps of: mixing and pulping the deinked sludge of the wastepaper, recycled pulp of the papermaking white water, recycled pulp of the papermaking wastewater, slag of chemical pulp and wastepaper pulp for future use; then molding on a net, pressing, drying, calendering, winding and manufacturing paper with pulp. The method provided by the invention has the advantages of simple production process, reduced production cost and same tightness degree of the produced environmental-friendly cardboard paper rolls; the ration and the thickness are the same; the tightness degree of the paper and the ring crush compression resistance reach the quality standards which are higher than the C grade; and the paper is applied to the paper of the industries including each type of paper tube, yarn cops, fireworks and the like.
Description
Technical field
The present invention relates to pulp technology for making paper, particularly relate to the manufacture method of environmental protection boxboard.
Background technology
3,050 ten thousand tons of China's paper in 2000 and paperboard production, to 7,980 ten thousand tons of national paper in 2008 and production amounts, a year consumption figure is 60 kilograms per capita.Paper and paperboard production are average annual in the period of past 8 increases by 12.78%, and consumption figure increases by 10.48% every year, all is higher than the Chinese national economy GDP average growth rate per annum same period.The paper industry of China is by nearly 10 years development, become the third-largest papermaking big country after the U.S., Japan, China is populous, the forest reserves are limited, and coverage rate is 16%, are lower than world average level 28%, the shortage of the forest reserves, do not satisfy the demand of paper industry to raw material, annual China all wants a large amount of paper of import, cardboard, paper pulp, accounts for 66% of China's paper and cardboard consumption figure.On the other hand; the environmental pollution of adopting the plant resources pulping and paper-making to be produced also becomes the problem of puzzlement China paper industry sustainable development; if can adopt an effective measure; actively reclaim discarded paper products; just can alleviate the present situation of papermaking raw material deficiency, also help conserving forests, protecting simultaneously environment.In recent years, the waste paper of China utilized development rapidly again, had accounted for 1/3 of all paper making raw materials.In visible future, the producer that utilizes waste paper to carry out pulping and paper-making will get more and more.Entire society is to the recovery of waste paper and utilize technology will give increasing attention and concern.
The characteristics that deinking is handled line are based on pulping, purification, screening, floatation and ink removing, hot dispersion, bleaching, carrying out washing treatment.Capital equipment has rotary drum pulping machine, HC Cleaner, pressurized screen, low dense desander, flotation cell, thickener, heat dispersion machine, bleaching tower etc.Because of the particularity of system process, the mode of each operation waste residue, printing ink filler and the fiber treatment of taking out of and utilize mode to differ in normal productive process.At present, owing to there is not processing method well, deinked sludge causes secondary pollution problem, is perplexing many papermaking enterprises.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of and can effectively utilize deinking mud, solve the secondary pollution problem, the method for utilizing deinking mud and coming production environmental protection boxboard for raw material with the reclaimed waste paper slurry.
Technical scheme of the present invention is as follows: a kind of method for preparing the environmental protection boxboard with deinking mud, comprise with deinking pulp, slurry, mthod of white water from paper making and reclaim slurry, pulp-making waste-water recovery slurry, chemical pulp screenings, secondary stock adapted after mixing making beating, through Top wire former, squeezing, drying, press polish, batch and manufacture paper with pulp, it is characterized in that: ⑴ slurry weight proportioning: deinking pulp, slurry (20 ~ 35): mthod of white water from paper making reclaims slurry (20 ~ 30): pulp-making waste-water reclaims slurry (20 ~ 40): chemical pulp screenings (5 ~ 10): secondary stock (10 ~ 25);
⑵ auxiliary material is a: ﹙ a ﹚ sizing agent alkyl ketene dimer weight ratio 0.30～0.40% to the oven dry stock consumption; ﹙ b ﹚ dry strength agent 2 ~ 5kg/t ton; ﹙ c ﹚ ative starch 12 ~ 18kg/t ton.
⑶ the concentration of surfing the Net: 0.3-0.7% online beating degree: 19 ° of-28 ° of SR;
⑷ precompressed pressurization: 1# conducts oneself with dignity or all adds, and 2# is pressurised into: 0.1-0.13 kilogram
The main pressure pressurizeed: 0.3-0.45 kilogram/m2
Malleation is pressurised into: 0.4-0.5 kilogram/m2
Press polish is pressurised into: 0.3-0.5 kilogram/cm;
⑸ become paper moisture weight content to be: become paper moisture 8～10%.
Ative starch among the described ⑵ is mainly taked to be injected on the wet web on the net.
The characteristic of the environmental protection boxboard that the present invention makes: the boxboard that makes is quantitative: 250 g/m2～500 g/m2; Tightness 〉=0.7g/cm3; Moisture content 8-10%; In the cross direction ration 5%; Folding strength is no less than 14 times.
Paper mill sludge (deinking mud) production environmental protection boxboard is in manufacturing process, because of slurry and wet end furnish difference, technical data instability cause quality problems such as paper tightness, ring crush intensity easily.The characteristic that the present invention reclaims according to deinking pulp, slurry, mthod of white water from paper making and starches, pulp-making waste-water reclaims slurry, chemical pulp screenings, five kinds of slurries of secondary stock, the research wet end furnish, making beating is to the influence of paper tightness, ring crush intensity.Research paper machine operation parameter guarantees that ative starch liquid best angle is ejected into paper, guarantees the bond strength between ply of paper.
The present invention adopts deinking pulp, slurry, mthod of white water from paper making recovery slurry, pulp-making waste-water recovery slurry, chemical pulp screenings, secondary stock to join and copies the environmental protection boxboard, effectively utilize deinking mud to be raw material, overcome the shortcoming of deinking mud comprehensive development and utilization difficulty, reduce landfill, burning and reclaimed the paper mill sludge pollution on the environment, reduced the input cost of sewage treatment plant's processing mud simultaneously.
It is simple that the present invention has manufacturing technique, and manufacturing cost reduces, the environmental protection boxboard paper roll degree of tightness unanimity of production; Quantitatively, the thickness homogeneous, paper tightness, ring crush intensity reach the above QUALITY STANDARD of C level, are applicable to industry paper such as present all kinds of paper tube, spool, fireworks.
