Abstract
The present invention relates to a biological delignification and mechanical pulping technology. A papermaking pulping process is realized by the steps that lignin is used for degrading microorganisms, the lignin in a papermaking raw material is properly degraded, a cellulose component is maintained, and the mechanical jordaning is additionally carried out. The process has the remarkable characteristic that chemical reagents are not needed (sodium hydroxide, sulfate, sulfite, etc.). The technology has no problems of black liquor treatment and alkali recovery, and is a clean production technology in the papermaking industry. The technology is also an innovation technology for environmental protection.
Description
The invention belongs to a kind of novel pollution-free paper making new technology of utilizing the biotechnology exploitation.
Paper industry is the important light industry of China, it plays important effect in national economy and people's lives, yet, because there is numerous little paper mills based on straw pulp in China, and environment is caused great harm, country has taked the resolute measure of closing to several thousand tame little papermaking of Basin of Huaihe River, this has great impetus to the pollution that alleviates Basin of Huaihe River, but, develop new paper technology, make it not produce environmental pollution and should be more active measure.
Biological paper-making be people's dream hide in the hope of new technology, all carried out a large amount of research both at home and abroad.China carried out tackling key problem research in the seventies, did not make great progress.In recent years domestic many research workers are still carrying out unremitting effort, carried out many-sided research, Shao's small melon is given birth to and is waited the research (Chinese papermaking, 1985 years the 4th phases) of once having done " whiterot fungi Phanerochaete chrysosporium is to the microbial degradation of lignin in the timber "; Hu Aizu etc. had once summed up " experience and the achievement of papermaking falls in Chinese non-wood fibrous raw material system " (Chinese papermaking, 1988 the 10th phases); Zhang Houmin etc. have also discussed the relation (Chinese papermaking, the second phase in 1994) of " biotechnology and paper industry "; Yu Huisheng etc. have also inquired into " whiterot fungi is to the biodegradation rule of straw and the potential application on bio-pulping thereof " (Chinese papermaking, 1989 the 1st phases).
Though the paper making raw material kind is various at present, all can be divided into three parts from chemical composition: cellulose, hemicellulose, lignin.Other component content is less, mainly contains: tannin, and pectic substance, resin, fat, wax, pigment, ash grades.Concerning three kinds of key components, cellulose is the main raw material that is used for papermaking, and lignin is the main component of hindering papermaking that should remove, and half fiber rope then can suitably keep.So the process of paper-making pulping is exactly the process that removes lignin from chemistry.
Therefore, understanding distribution and the effect of lignin in paper making raw material is the most important condition of grasping the paper-making process basic principle.We know, fiber rope is that the chain macromolecule compound by the glucose poly is constituted, and its fine long molecular structure makes it soft and intensity is arranged, be paper property body mainly is provided.Lignin then is the macromolecular compound by the three-D space structure that contains fragrant side group, and it acts on as a kind of adhesive, and fiber laterally is bonded into one, and makes it to become rigid structure and has high strength, and the caulome that becomes plant supports other parts.
The process of paper-making pulping promptly is to remove wooden rope by the whole bag of tricks, discharges cellulosic process.This can reduce
(1). partial destruction lignin and do not remove the mechanical jordaning method and the pyrohydrolytic method of wooden rope only.Its characteristics are that lignin does not remove, and papery is hardened (crisp), only can make low-grade paper or starch mixed copy paper with other.
(2). and the alkaline process delignification of chemical delignification (lime method ...), its characteristics are that delignification is more thorough, the papery function admirable.
(3). the semichemical pulping method: Chemical Pretreatment combines with machinery pulping, and this method papermaking gained papery performance is better than first kind, and inferior to second kind.Wherein, except that mechanical jordaning, all the other two kinds of methods all produce a large amount of waste water, cause environmental pollution or expensive disposal cost.
The objective of the invention is to propose a kind of free of contamination bio-pulping technology promptly: the pulping technology for paper-making that biological delignification combines with machinery pulping.
This method papermaking gained papery performance is better than first kind, and inferior to second kind.Its great advantage is without chemical agent, does not arrange pulping sewage, can be described as " clean paper making technology ".Its basic principle is to adopt the microbial decomposition lignin, keeps cellulose, realizes pulping process.
Technical process of the present invention is as follows:
Raw material (wheat straw, straw etc.) → water logging → biological delignification → boiling sterilization → mechanical jordaning → copy paper
The raw material range that is suitable for this invention is wide, and the raw material commonly used of papermaking at present all can adopt; Its first step processing procedure is water logging, and main purpose is with the inorganic impurity flush away, and raw material is soaked into, and is beneficial to the subsequent biological treatment process, and the water logging time is different and different according to material, generally spends several hrs to tens hour; Biological delignification is the master operation of this technology, and the raw material after will soaking rises to the biological treatment workshop, piles high 2～3 meters, long 5～10 meters, wide 3～5 meters raw material pile is provided with on the buttress and cultivates the strain liquid spray equipment, inserts air leading-in conduit in the buttress, with the air compressor machine oxygen supply of regularly ventilating, make biological normal growth, lignin degrading is looked different raw material, the general cultivation 3～15 days, degraded can be finished; Raw material behind the delignification enters the boiling pond, with steam (105～110 ℃) sterilization 30 minutes, to kill wooden rope degradation bacteria; Through the sterilization after raw material enter fiberizer, carry out mechanical jordaning, behind the defibrination routinely technology copy paper.
The technical indicator that the present invention can reach is: lignin degradation rate 20-40%; Slurry moisture 70-80%; Beating degree: 35-55 degree (SR); Breaking length: 1200-1400M (absolute tensile strength: 15-30 KG/15MM); Ring is pressed Zhang Du: 5-8N
*M/G).
Bacterial classification of the present invention is to be to lead also the seldom microorganism of degraded cellulose with the lignin degrading, the common conchoidal that comprises is removed from office ear bacterium (Panus Lanchatus), variegated manyzoned polypore bacteria (Polyporus versicolor), the tertia bacterium (Pleurotus Ostreatus) of picking up the ears, grey official's shelf fungus (Fomes Lignosus) and artist's conk bacterium (Ganoderma applenatum) etc.
The effect that the present invention can reach is: utilize conventional paper making raw material, adopt biology to take off wooden rope technology, the problem of environmental pollution of having avoided present chemical method delignification to cause, its delignification efficient is between 20～50%, can make common or low-grade paper, big for the such paper demand of China, and the not abundant big country of timber, this technology has its immeasurable meaning.
Embodiment: the 10kg straw, water logging 4 hours is positioned over then and introduces bacterial classification conchoidal leather ear bacterium in the culturing room.Continuous Cultivation 10 days is ventilated, and sprays nutrient solution every day, and the liquid that drenches still can continue to use.Cultivation finishes to place in the steamer and sterilized 30 minutes, enters paste mill grinding then, and the gained technical indicator is as follows:
