Description
Technical field
The invention belongs to pulp and paper technology field, be specifically related to paper pulp, its preparation method prepared by a kind of bamboo fibre and the paper products of making thereof.
Background technology
Because the shortage of current worldwide timber resources increases the weight of day by day, in the situation that not destroying forest and environment, producing paper pulp and papermaking becomes the target that each papermaking enterprise is pursued.As the scheme addressing this problem, utilize 1 year or 2 years raw plants as: farm waste, bamboo, sugaring afterwards discarded sugarcane stem, rice wheat straw etc. are received publicity by the technology that non-wood plant fibre is manufactured paper pulp as main material always.
Conventionally cultural paper refers to printing, is also offset paper, or the abbreviation of light weight coated paper, generally between 60 grams to 120 grams, lower than 60g be writing paper, higher than 120 grams of pair copper paper that cry that have the glossiness of being coated with.Offset paper and two copper paper are high-grade paper products.Paper for daily use refers to, for looking after individual at home, go out to wait all kinds of health wiping paper usings of using, and comprises roll tissue, interfold toilet paper, Boxed facial tissue, pocket face-tissue, paper handkerchief, napkin paper, tissue, kitchen paper handkerchief etc.
There is shortcomings in cultural paper and the paper for daily use of prior art, use Original Pulp more, because needs are cut down a large amount of timber, has a strong impact on the ecological balance of environment and cause long-range negative consequence; The tensile strength of cultural paper prepared by part Original Pulp, pliability, water imbibition do not reach required standard; And prior art is in order to increase the whiteness of paper, and the slurrying that all European use process is bleached in pulping process is produced as raw material, and the agent of floating that bleaching is used mainly contains two kinds of Oxidizing and Reducing Agents; Mainly take oxidant at present as main, and conventional have chlorine, hypochlorite, a chlorine dioxide etc.; The bioxin that the organic chloride producing 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 of receiving.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
The object of the invention is to overcome the shortcoming of prior art, the paper pulp that provides a kind of bamboo fibre to prepare, this paper pulp has good performance parameter, can substitute conventional wood pulp, and is better than conventional wood pulp.
Another object of the present invention is to provide a kind of preparation method of bamboo fibre paper pulp, the method has that yield is high, simple to operate, convenient for production, cost is low, the characteristic of environmental protection;
The 3rd object of the present invention is to provide a kind of cultural paper of being prepared by bamboo fibre paper pulp and paper for daily use.
Object of the present invention is achieved through the following technical solutions: paper pulp prepared by a kind of bamboo fibre, the whiteness of described paper pulp is 20～40% ISO, tensile index >=7.9Nm/g, folding strength is 15～200 times, fracture length is 5～10km, ash content≤1%, tearability is 200～650mN, beating degree is 10～25 ° of SR.
The preparation method of above-mentioned bamboo fibre paper pulp, it comprises the following steps:
S1. raw material size degradation: choosing bamboo fibrid is raw material, and it is the fiber powder of 2～4cm that raw material dry method size degradation is become to length;
