Abstract
The invention belongs to the technical field of pulping and papermaking and particularly relates to life paper made from bamboo. The whiteness degree of paper pulp is 25-40% ISO, the tensile index is larger than or equal to 8 Nm/g, the folding strength is 15-140 times, the fracture length is 6-8 km, the ash content is smaller than or equal to 1.2%, the tearing strength is 150-600 mN, and the beating degree is 16-22 degree SR. The produced life paper is not subjected to the bleaching process, the life paper made from bamboo reserves the natural color of the bamboo and has good performance parameter, conventional wood pulp can be replaced with the bamboo, the bamboo is superior to the conventional wood pulp, it is avoided in that chemicals used in the bleaching process remain in the life paper, the manufactured bamboo pulp product does not contain dioxin and can adsorb organic halide and other carcinogenic substances, 100% of natural color of bambusa emeiensis is kept, pollution of waste gas and waste liquor caused by bleaching to the environment is eradicated, and thus the method has the characteristic of ecological environmental protection.
Description
Technical field
The invention belongs to pulp and paper technology field, be specifically related to a kind of bamboo paper for daily use.
Background technology
The fibre morphology of bamboo and chemical composition show good pulpability, evaluate from pulpability level pulp strength, and bamboo is good papermaking raw material, is only second to needlebush, close to leaf wood.Along with the development of paper industry; wood substituted by bamboo alleviates the pressure of paper industry to wood raw material demand; adapting to the requirement of ecological environmental protection is that bamboo pulp provides a wide development opportunity; for a long time, utilize bamboo for main material and manufacture the technology of paper pulp by non-wood plant fibre and receive publicity always.
Paper for daily use refers to for looking after individual at home, go out to wait all kinds of health wiping paper usings used, comprise roll tissue, interfold toilet paper, Boxed facial tissue, pocket face-tissue, paper handkerchief, napkin paper, tissue, kitchen towels etc., in order to increase the whiteness of paper in prior art, in pulping process, all European use is produced as raw material through the slurrying of bleaching, and bleaches the drift agent used and mainly contains Oxidizing and Reducing Agents two kinds; Main based on oxidant at present, comparatively conventional has chlorine, hypochlorite, chlorine dioxide etc.; The bioxin that the organic chloride produced in production contains, furans etc. have carcinogenic, mutagenicity, cause birth defect, multiple cranial nerve pathology and anxious toxicity, and the sewage of discharge has larger harmful effect to the water body environment received.Slurry, after the bleaching of strong oxidizer, has the damage in different Chengdu to fibre strength, intensity, toughness decline, and the product of production in use easily exists hair, dry linting, the problem that wet strength reduces.
Summary of the invention
In order to overcome in prior art, a large amount of employing timber is as pulpwood material to problems such as the felling of timber, and the invention provides a kind of is the paper for daily use that raw material manufacture by bamboo.
Object of the present invention is achieved through the following technical solutions: a kind of bamboo paper for daily use, it is characterized in that: the manufacturing process of described bamboo paper for daily use comprises the following steps: 1, choosing bamboo fibrid is raw material, become by raw material dry method size degradation length to be the bamboo chip of 2 ~ 3cm; 2, carry out boilery reason after bamboo chip and cooking liquor being mixed by the solid-liquid ratio of 1:3 ~ 4, control temperature, at 120 ~ 140 DEG C of insulation 50 ~ 70min, obtains the high-hardness pulp that hardness is permanganate number 25 ~ 40; Wherein, described cooking liquor is the NaOH of 10 ~ 17%; 3, discongest in above-mentioned high-hardness pulp feeding high-density paste mill, the time of discongesting is 20 ~ 30min; Diluted slurry, to concentration 4 ~ 6%, is carried out defibrination, obtains the slurry that beating degree is 16 ~ 22 ° of SR by the bamboo pulp after 4, discongesting with thin phenol water dilution; 5, the slurry after defibrination is screened, slurry adjustment slurry concentration to 8 ~ 11% after screening, send in vacuum pulp washing machine and wash, through washing to obtain paper pulp, pulled an oar by paper pulp at double-arc spline defibrination machine, its beating consistency is 5%, beating pressure is 0.2MPa, making beating electric current is 35A, and the pulp quality standard obtained after making beating is: beating degree 42 ° of SR, and making beating weight in wet base is 7g; 6, the slurry after making beating is manufactured paper with pulp, obtain described natural color toilet paper, the described pulping comprised obtaining after above-mentioned making beating of manufacturing paper with pulp is manufactured paper with pulp, described manufacturing paper with pulp is carried out in single cylinder Yankee dryer list woollen blanket toilet paper machine, and obtain natural color toilet paper of the present invention after manufacturing paper with pulp, described natural color toilet paper is quantitatively 13.5g/m2, horizontal suction range 50mm/l00s, tensile index is 8.6Nm/g, pliability 106mN, and brightness is 26%.
Further, the whiteness of described paper pulp is 25 ~ 40%ISO, tensile index >=8Nm/g, and folding strength is 15 ~ 140 times, and fracture length is 6 ~ 8km, ash content≤1.2%, and tearability is 150 ~ 600mN, and beating degree is 16 ~ 22 ° of SR.
The present invention has following beneficial effect:
The paper for daily use that the present invention produces is without bleaching process, bamboo paper for daily use remains bamboo true qualities, there is good performance parameter, conventional wood pulp can be substituted, and be better than conventional wood pulp, avoid the chemical residues that uses in bleaching process in paper for daily use, and in prepared bamboo pulp product containing two uh the carcinogen such as English and Adsorbable organic halogens, keep the natural gray of cizu 100%, and stopped waste gas because bleaching produces, waste liquid is to the pollution of environment, therefore, inventive method has the characteristic of ecological, environmental protective.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described, and protection scope of the present invention is not limited to the following stated.
embodiment:
A toilet paper prepared by cizu paper pulp, its preparation method is:
Adopt cizu paper pulp prepared by above-mentioned enforcement 1-5, pulled an oar by above-mentioned fibre pulp at double-arc spline defibrination machine, its beating consistency is 5%, beating pressure is 0.2MPa, making beating electric current is 35A, and the pulp quality standard obtained after making beating is: beating degree 42 ° of SR, making beating weight in wet base is 7g.Slurry after making beating is manufactured paper with pulp, obtains described natural color toilet paper.The described pulping comprised obtaining after above-mentioned making beating of manufacturing paper with pulp is manufactured paper with pulp, and described manufacturing paper with pulp is carried out in single cylinder Yankee dryer list woollen blanket toilet paper machine, obtains natural color toilet paper of the present invention after manufacturing paper with pulp.Described natural color toilet paper is quantitatively 13.5g/m2, horizontal suction range 50mm/l00s, and tensile index is 8.6Nm/g, pliability 106mN, and brightness is 26%.
