Description

A kind of papery news media
Technical field
The present invention relates to newsprint technical field, especially relate to a kind of papery news media.
Background technology
Newsprint is the main use paper of newpapers and periodicals and books, needs to meet that papery pine is light, have preferable elasticity, ink absorption Well, the features such as have certain mechanical strength, opaqueness good.China is paper production, consumption, import big country, with China The growth of demand for paper products, wood pulp supply much can not meet demand, causes import volume to increase sharply.Wood fibre either from All it is far above non-wood in performance or technique, but China's forest resourceies are less, China's lumber fibre supply is in decline Trend.
Waste paper is recycled as Renewable resource, the grass class slurrying of waste paper pulp-making ratio can energy saving in a large number, Because do not need the maximum cooking section of Sewage water discharge capacity using Deinking Pulp, and the discharge of BOD and COD of deinking wastewater Amount is easier to be up to state standards after water process.The utilization of secondary stock, solves process paper industry contaminated wastewater and asks Topic, is also a kind of effective way solving China's wood raw material shortage simultaneously.
China is the country that world's bamboo resource is the abundantest, bamboo class is cultivated and processing and utilization is the longest, cultivated area, Accumulation and annual production occupy the hat in the world.Bamboo has that easy cultivation, growth be fast, cycle is short, renewable, survival rate is high, the period of felling in turn is short, The big feature of yield.Bamboo is the raw material being best suitable for papermaking in addition to wood, and the fibre morphology of bamboo wood and content are with needlebush very Approximately, content of cellulose is high, and fiber is elongated solid, and plasticity is good, and fibre length, between leaf wood and needlebush, is paper pulp The quality raw materials of papermaking, bamboo paper pulp papermaking has good performance and relatively low cost.
Patent of invention CN1079127C discloses a kind of method that waste paper produces regenerated newsprint, and the method waste paper is Raw material, adds appropriate NaOH, Na2SiO3In chemical raw material and water, through steaming and decocting, dehydration, bleaching, making beating, purification, copy paper, cut paper Get product.This invention not only has and can make full use of waste paper regenerated newsprint, thus greatly reducing paper grade (stock) fibril raw material Consumption and the advantage of consumption of wood, but also there is minimizing environmental pollution, reduce production cost.But secondary stock prepares Newsprint surface low intensity, bad mechanical property.Patent of invention CN102041747B discloses a kind of environmental protective newsprint paper, is with low Density polyethylene, linear low density polyethylene, PUR, modified heavy calcium carbonate, modified coal ash preparation obtain.This invention Paper, with high molecular polymer as substrate material, carries out to Calcium Carbonate and flyash composite modified, and adds other additives, utilizes The macromolecule interfacial principles of chemistry and macromolecule modified feature, after processing through special process, are combined using polymer mixed, filler Modified, polymer and filler plasticizing, extrusion curtain coating, calendering formation technique are made, and to energy saving, protect national resource that there have to be non- Often good meaning.But the newsprint that this invention prepares can not recycle, environment is caused with certain burden.
