  • FIBER RESOURCE AVAILABILITY FOR THE CHINESE PULP AND PAPERINDUSTRY

    作者：XiangJu; Zhong 刊期：2004年第A01期

    Total P & B production in Mainland China has been reported to be 37.8 million metric tons for the year 2002. A goal of 50-60 million metric tons of total P & B production has been set for the year 2010. By that time, domestic virgin woodpulp production will be doubled, with pulpwood supply from plantations in the cou...

  • SYNERGISTIC EFFECTS BETWEEN BIRCH CHEMICAL MECHANICAL PULPS AND ASPEN BLEACHED KRAFT PULP

    作者：EricC.Xu; YajunZhou 刊期：2004年第A01期

    In this investigation, two different grades of birch chemical mechanical (P-RC APMP) pulps and aspen market bleached kraft pulp were compared by low consistency refining of the pulps separately and in different combinations. In addition, the separately refined pulps were also combined to compare with the pulps from t...

  • CONTROLLING DARKENING REACTIONS DURING MECHANICAL PULPING WITH ADDITIVES - A POSSIBLE APPROACH TO IMPROVING BRIGHTNESS AND BLEACHABILITY

    作者：GeorgeX.Pan; GordonJ.Leary; EricY.Zhang; EricC..Xu 刊期：2004年第A01期

    The first part of this paper summarizes relevant literature information, which rationalizes our selection of chemicals. The second part reports some preliminary screening results. We have investigated a wide range of reagents, chosen for their different chemistries and divided into seven classes: (1) reducing agents,...

  • ALKALI DARKENING AND ITS RELATIONSHIP TO PEROXIDE BLEACHING OF MECHANICAL PULP

    作者：ZhibinHe; Yon2haoNi; EricZhang_ 刊期：2004年第A01期

    The effect of alkalinity, transition metals and oxygen on alkali darkening of mechanical pulp, and its relations to subsequent peroxide bleaching were investigated. The chromophores generated under mild conditions of an alkaline treatment can be destroyed in a subsequent peroxide stage. Peroxide-resistant chromophore...

  • IMPACT OF APPLYING BCTMP TO WOOD-FREE LWC ON ITS PERFORMANCE

    作者：KaitangHu; YonghaoNi; XuejunZou; YajunZhou 刊期：2004年第A01期

    Substituting bleached CTMP (BCTMP) for chemicalpulps, such as bleached hardwood kraft pulp in manypaper grades is in rising demand for reducing costand improving product performance. In this paper weinvestigated the effect of substituting aspen BCTMPfor hardwood krat~ pulp (varying from 10% to 30%)on product performa...

  • EFFECT OF NaOH CHARGE ON FIBER CHARACTERISTICS OF P-RC APMP PULP

    作者：FangongKong; JiachuanChen; GuihlmYang; EhaochengLi; HuaiyuZha~ 刊期：2004年第A01期

    Fiber screen analysis, fiber quality analysis and SEMobservation were used to investigate the effects ofNaOH charge on fiber characteristics in TriploidPopulus Tomentosa P-RC APMP pulping in thispaper. The results showed that increasing NaOHcharge in P-RC APMP process could reduce energyconsumption and fines percent,...

  • P-RC APMP PULPING OF THE TRIPLOID OF POPULUS TOMENTOSA

    作者：FangongKong; JiachuanChent; HuaiyuZhan; GuihuaYang; ZhaochengLi 刊期：2004年第A01期

    The technology parameters of P-RC APMP processof the triploid of populus tomentosa and thecomparison of P-RC APMP with one and two stageofpretreatment were investigated in this paper. Theresults showed that in the chemical pretreatment thecharge of NaOH and H202 were the main factors thataffected the pulp qualities. ...

  • OPTIMIZING EUCALYPTUS PULP REFINING

    作者：VailManfredi 刊期：2004年第A01期

    This paper discusses the refining of bleachedeucalyptus kraft pulp (BEKP).Pilot plant tests were carded out in to optimize therefining process and to identify the effects of refiningvariables on final paper quality and process costs.The following parameters are discussed: pulpconsistency, disk pattern design, refiner...

  • STUDY ON FORMAMIDINE SULPHINIC ACID BLEACHING OF POPLAR APMP

    作者：MeiyunZhang; ZhaooinLu 刊期：2004年第A01期

    Bleaching of poplar APMP with Formamidinesulphinic acid (FAS) was investigated in this paper.The effects of FAS charges, ratio of treatment on thebrightness gain, color reduction and pulp strengthwere studied. A single-stage FAS bleaching wasoptimized. Under the conditions of 10 % pulpconsistency, 60 minutes time and...

  • COMPARISON OF APMP PULP CHARACTERISTICS OF JUVENILE TRIPLOID CHINESEWHITE POPLAR IN SALINESOIL WITH THAT OF NORMAL5-YEAR POPLAR

Thus, the studies concerning impacts ofthose factors on paper aging are required. In thispaper, an accelerated paper aging was carried out toinvestigate the effects of acid a...

  • MECHANISM OF CHLORATE FORMATION IN CHLORINE DIOIXDE DELIGNIFICATION

    作者：Byung-HoYoon; Li-JunWangI; Se-JongKim 刊期：2004年第A01期

    The effect of pH on chlorate formation duringchlorine dioxide delignification of oxygen delignifiedkraft pulp was studied. Chlorate formation was foundto increase slightly when pH was increased from 1.8to 2.5, further increase of pH decreased chlorateformation.The above phenomenon is explained by thecombination of tw...

  • KINETICS OF DELIGNIFICATION AND CARBOHYDRATE DEGRADATION DURING OXYGEN BLEACHING

    作者：K.LNguyen 刊期：2004年第A01期

    Carbohydrate degradation during oxygen bleaching isassociated with cleavage reactions. It is apparent thatthe loss of the cellulose DPis strongly affected by(degree ofpolymisation) the extent of thedelignification. A strong linear correlation can beestablished between the DP of cellulose chains andthe residual lignin...
