Abstract:Magnetic papers have been successfully prepared from bleached spruce kraft pulps via lumen loading or in situ synthesis process. Good magnetic performance could be obtained in the optimal preparation conditions: by method of lumen loading, stirring speed 2500 r/min, stirring time 30 min; by method of in situ synthesis, reaction temperature 60℃and stirring speed 1000 r/min. The loading degree of magnetic particles of magnetic paper by method of lumen loading is lower than that by in situ synthesis.The structure and properties of magnetic paper were studied by using scanning electron microscope (SEM), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The XRD results confirmed that the magnetic particles are Fe3O4;the magnetic properties of the in situ synthesis papers are lower compared to the lumen loading papers due to the nanosized magnetite particles possess super-paramagnetic behavior;The SEM micrograph showed that the size and the distribution uniformity of the magnetic particles inside the lumen for the in situ synthesis papers are much better than that of the lumen loading papers.

Abstract:LXS (laccase/xylanase system) was obtained after regulated cultivation of Flammulina velutipes.  Pinus massonia kraft pulp was pretreated with LXS before DED sequence bleaching and the result were compared with the LMS (laccase/mediator system) pretreatment. The result showed that the optimal conditions of pretreatment were as following: pH 4.2, pulp consistency 3%, temperature 40℃, treatment time 3 h, and enzyme dosage 10 IU/g. The kappa numbers of the pulps which were pretreated with LXS and LMS and then extracted with alkali were reduced 9.2% and 8.3% compared with the control sample respectively. The brightness of the pulp pretreated with LXS and then bleached with DED sequence was close to that of the bleached pulp pretreated with LMS, and was 6.0% higher than that of the control pulp. Moreover, the strength of these two bleached pulps pretreated with LXS or LMS systems was similar and there was no obvious decrease compared with that of the control pulp.

Abstract:There are many advantages associated with the use of silver-doped zeolite as antibacterial agent, such as high durability, high antibacterial performance, and excellent thermal stability and safety. In this work, the use of silver-doped zeolite in paper coating was preliminarily investigated, and the influence of zeolite dosage on paper properties (including optical properties and printability) and antibacterial performance was elucidated. The electron probe micro-analyzer (EPMA) and atomic force microscope (AFM) were used in the analysis of the surface morphology of the coated paper samples. The experimental results showed that, the use of silver-doped zeolite significantly contributed to the improvement on paper's antibacterial performance. Paper brightness was somewhat negatively influenced as a result of zeolite addition. It was also found that, the effect of zeolite addition on paper color, printability, and surface morphology was only negligible.

Abstract:In recent years, the high yield pulp (HYP) has been found an increasing application in value-added paper grades due to its cost advantages and unique properties. However, the concern still remains on the negative effect of HYP on the optical properties of fine papers. optical brightening agents (OBA) can be used to diminish or offset the negative effects of HYP on the optical properties of fine paper. The brightening efficiency of OBA depends on its efficiency and retention in the paper sheets. In this paper, some parameters influencing the effectiveness and retention of OBA were discussed, such as HYP substitution ratio, HYP brightness, anionic trash and fines in HYP. The new advances on the brightening efficiency of OBA in HYP-containing papers were summarized.
 
Key words:optical brightening agent (OBA); high yield pulp (HYP); fine paper; optical properties; OBA retention

Abstract:Over the period, most of the fiber lines have deviated significantly from the standard operating procedures provided by the equipment/technology suppliers for a given raw material. Our experience shows that the two fiber lines are most likely to have different pulp output and quality even if they operate with more or less similar technology and chip furnish. This could be due to many reasons such as operating practices and the use of specialty chemicals to enhance productivity and quality. Though most of the fiber lines aim to maximize their profit but the vital question is as to how to minimize these variations. While working with different fiber lines, our strategy is to interact closely with the operating management to optimize pulping process while running applications such as digester additive, pitch control, and DCM extractive, brown stock washing and scale control applications to improve pulp quality and output. With a thorough understanding of the wood science and chemistry, and that of the pulping technology used, these efforts are clubbed with the innovative use of the aforesaid applications. Additionally with continuous focus on introducing new technologies to the fibers lines such as partial auto-causticizing technology, we not only provide an impetus to mill's ongoing efforts for an improved environmental management but also help to reduce the production cost. Overall our BEST PRACTICES are aimed to provide continuous improvement to the fiber lines to achieve their bottom lines on a sustainable basis.
