Description
Technical field:
The present invention relates to pulp technology for making paper, particularly a kind of is the manufacture paper with pulp method of paper for daily use of raw pulp with the salix monogolica.
Background technology:
Salix monogolica is a kind of shrub that is grown in the desert region, has effect windproof, that fix the sand; Salix monogolica fast growth, cycle weak point, living diameter on average can reach 2-3cm in 3 years, more than the high 3m; General 3 years stumps once can send more shoots in 1 year, otherwise the meeting natural death; Because country strengthens the sand control dynamics, implemented many preferential policies in recent years, the area of artificial growth salix monogolica is constantly enlarged.It is the method for raw material papermaking with the salix monogolica that Chinese patent discloses two kinds, wherein " salix monogolica manufacture paper with pulp boxboard and fluting medium " (number of patent application: 96117325.4) disclosing a kind of is the method that raw material is made low-grade paper-corrugated paper with the salix monogolica, " salix mongolica imonium pulping and paper-making method " (number of patent application: 00113846.4) disclosing a kind of is the method that raw material is made wrapping paper with the salix monogolica, analyze from technological layer, more than two kinds of methods all can't realize with the salix monogolica being the requirement of the paper for daily use that the raw material production technical merit is higher, product specification is higher.
Summary of the invention:
The purpose of this invention is to provide a kind of is the method for raw material production paper for daily use with the salix monogolica, its procedure is with close with the papermaking straw pulp method, paper delivery rate and production cost are close with it, can make full use of the characteristic of psammophytes, realize that the integrated sustainable development of woods paper requires target.
Purpose of the present invention realizes by following scheme: a kind of is the manufacture paper with pulp method of paper for daily use of raw pulp with the salix monogolica, mainly comprises the slurrying and the two parts of manufacturing paper with pulp, and wherein, pulping process comprises dry raw material preparation, batch cooking, washing, bleaching; Pulping method comprises making beating, manufactures paper with pulp, and wherein dry raw material preparation is to be raw material with the salix monogolica, cuts into the long tablet of 15～35mm, tablet moisture: 10～30% through chaffcutter; The method parameter of batch cooking is:
