Abstract
The chemical and mechanical straw pulp is produced through the steps of digestion and disinfection of straw material, microbe treatment, chemical presoaking, mechanical grinding and bleaching without chloride to produce bleached paper pulp, the microbe treatment is using microbe to degrade lignocellulose at 25-35 deg.c for 5-6 days. The chemical and mechanical straw pulp has high strength, good bleaching property, low pollution load, breaking length up to 4000-5000 m and whiteness up to 60-70 % ISO, and is suitable for making high and middle grade packing paper, newspaper and writing paper.
Description
The present invention relates to the technology that a kind of Biological Pretreatment prepares chemical mechanical straw pulp, belong to the papermaking technical field.
Non-wood pulp accounts for more than 80% of paper pulp total output in China's paper industry.The mode of production is based on soda pulping process and chlorine bleach; because the alkali recovery equipment investment is big; extraction rate of black liquor is low; straw pulp alkali yield only accounts for 1～1.5% of industry total alkali yield in actual applications; the macroscopic view alkali recovery has only 0.5%～1%; residual alkali more than 99% is along with black liquor discharges; water system and soil is on every side caused severe contamination, referring to " Chinese papermaking industrial expansion and alkali reclaim and environmental protection " literary composition of " Chinese papermaking " fourth phase in 1996 the 46th～50 page of disclosed Pan's tin five.Mechanical feedback is that raw material grinds the pulping technique of separating direct pulping through machinery, is that mechanical pulp yield height, the pollution of raw material production is little with timber, has good printability.But because the grass as raw material fiber is shorter, fiber is stiff, heteroproteose cell content height, and the direct mechanical mill is separated the pulping intensity difference, does not almost have practical value.Carry out machinery pulping after utilizing the microbial technique pretreated feedstock, can suitably improve pulp strength.But the raising of intensity is very limited, and fracture length only is 1200～1400m.Grass as raw material carries out the machinery mill and separates the chemi-mechanical pulp that makes after a small amount of chemicals preimpregnation, have intensity preferably, but whiteness is low, bleachability is poor.According to " metal ion are to the influence of wheat strawization machine pulp brightness and bleachability " such as " Shandong papermaking " nineteen ninety the 2nd phase the 2nd～10 page of disclosed Chen Jia river etc. " research of the inferior sodium preliminary treatment of wheat straw with alkaline chemi-mechanical pulp " and " Chinese papermaking journal " the 1st phase in 1996 the 24th～27 page of disclosed horse river in Guangxi literary compositions, they are carrying out certain research aspect wheat strawization machine slurry pulping process and the bleaching, the result shows through low and pollutes no chlorine and float agent--hydrogen peroxide bleaching, wheat strawization machine slurry also is difficult to reach 50%ISO at present, can only be used to produce low-grade paper such as primary colors wrapping paper and corrugated paper, the floating property of difficulty of careless class machine slurry becomes the key that limits its extensive use.
The purpose of this invention is to provide a kind of low pollution, high performance grass as raw material new pulping process, promptly prepare the pulping technique of chemi-mechanical pulp with microbial pretreatment.
The objective of the invention is to be achieved through the following technical solutions.
Technology of the present invention comprises the steps: that grass as raw material → boiling sterilization → microbiological treatment → chemical presoaking → machinery mill separates → chlorine-free bleaching → bleached pulp.
Grass as raw material of the present invention mainly contains wheat straw or straw.
Carry out boiling sterilization after the grass as raw material segment, liquor ratio 1: (4～6), 110～120 ℃ of temperature, 20～30 minutes.This is in order to kill original microorganism in the raw material on the one hand, is the leachable thing that increases raw material by heat treatment on the other hand, nutrition is provided for institute's inoculating strain, promotes the growth and breeding of bacterial strain, shortens the biological treatment cycle.
Material behind the above-mentioned boiling sterilization is carried out microbiological treatment, and bacterial strain uses therefor is the ligocellulose degradation microorganism, and the biological treatment condition is generally: inoculum concentration is 5～10% percentage by weights (dry weights), 25～35 ℃, cultivates 5～6 days.
Above-mentioned ligocellulose degradation microorganism mainly comprises yellow transverse hole fungus (Poria subacida), glossy ganoderma (Ganoderma lucidum), variegated wooden rainbow conk (Coriolus versicolor), Phanerochaete chrysosporium (Phanerochaete chrysosporium).
The above-mentioned material of crossing through microbiological treatment is carried out chemical presoaking, and condition is a liquor ratio 1: (4～6), the ratio of liquid weight (the raw material dry weight with), presoak is Na
2SO
34～6% percentage by weights (with the percentage by weight of raw material dry weight, down together), NaOH 0～1% percentage by weight, 130～140 ℃, 20～30 minutes.
Raw material after the preimpregnation is separated pulping through the machinery mill, again through obtaining bleached pulp behind chlorine-free bleaching such as the hydrogen peroxide bleaching.
Compared with the prior art, the excellent results of biological treatment process of the present invention is: one, directly microbe inoculation cultivation of raw material sterilization back does not need to add any exogenous nutrition composition; Two, the biological treatment cycle is short, yield is high.The ligocellulose degradation microorganism generally is first degradation of hemicellulose and cellulose, xylogen degradation then to the degraded of raw material.So the biological treatment cycle that with the delignification is purpose is longer, is unfavorable for actual production.The present invention utilizes microorganism to the cellulosic part degraded of raw material wood, makes raw material loose, softening, thereby helps the infiltration of chemicals, improves the efficient of chemical presoaking, be not purpose with the delignification, so the biological culture cycle is short, the yield height.
The chemical mechanical straw pulp of the present invention preparation, because grass as raw material is after microbiological treatment is softening, again through a small amount of chemicals preimpregnation, pulp strength height, the bleachability that makes after the machinery mill is separated is good, pollutional load is low.At first, bioid machine slurry intensity obviously improves, and fracture length can reach 4000～5000m; Secondly, after the no chlorine of low pollution floated agent-hydrogen peroxide bleaching, whiteness can reach 60～70%ISO, and bleachability improves greatly.Can be used to manufacture paper with pulp medium-to-high grade wrapping paper, newsprint and writing paper etc.CODcr load in the factory effluent only is 1/5 of chemical pulping, and organic chloride (AOX) content is zero, can realize qualified discharge through simple biochemical treatment.The paper pulp pollution that this technology is produced is little, performance good, for Straw Pulp provides a practicable new way to low pollutionization development.
The present invention will be further described below in conjunction with embodiment.
Embodiment 1. raw materials are wheat straw, and step is as follows:
Wheat straw segment to 3～4 centimetre, liquor ratio 1: 4,110 ℃ of boiling sterilizations 30 minutes, the material behind the boiling sterilization carries out microbiological treatment, inoculation glossy ganoderma bacterium, 5%, 28 ℃ of inoculum concentration was cultivated 5 days.
The above-mentioned material of crossing through microbiological treatment is carried out chemical presoaking, and condition is liquor ratio 1: 4, and presoak is Na
