项目摘要
Canadian northern bleached softwood kraft (NBSK) market pulps represent the worldwide benchmark for fibre strength, length, fineness, and uniformity. Better pulp quality control, especially its fibre strength, is important to maintain this superiority in the marketplace. Fibre strength depends mainly on intrinsic fibre properties such as the degree of cellulose crystallinity and chemical constituents such as lignin, hemicullose, and hexenuronic acid (HexA). These intrinsic properties also affect processing, such as digestibility and bleachability. In addition, the degree of fibre deformation incurred during pulping process also affects how the fibre delivers its strength in a network during sheet formation. All of these parameters have been shown to be important, however, aside from lignin, none can be easily measured in a timely manner for process control. The present research will prove principle on a novel Raman system, and systematic chemometric approach allowing for rapid spectral data acquisition and definitive spectrochemical analysis of wet pulp under harsh manufacturing conditions. Electro-optical instrumentation research will lead to backscattering sampling geometries and confocal parameters, coupled with express laser wavelength, power and resolution, all selected to maximize the information contained in signature spectral features. The instrument system will incorporate sophisticated chemometrics strategies, employing wavelet transform and template-guided genetic-algorithm feature selection with multivariate classification to extract maximum analytical information from raw Raman spectra. A program of analysis correlating spectrochemical observations with conventional characterization of fibre and end-use sheet properties will prove principle toward a comprehensive Raman gauge for the instantaneous determination of pulp quality vis-a-vis paper appearance and strength.
加拿大北方漂白软木硫酸盐浆(NBSK)市场纸浆代表了纤维强度、长度、细度和均匀性的全球基准。更好的纸浆质量控制,特别是其纤维强度,对于在市场上保持这种优势非常重要。纤维强度主要取决于纤维的内在性质,如纤维素结晶度和化学成分,如木质素、半羟甲基纤维素和己烯糖醛酸(HexA)。这些内在性质也影响加工,如消化性和漂白性。此外,在制浆过程中引起的纤维变形程度也影响纤维在纸张形成期间如何在网络中传递其强度。所有这些参数已被证明是重要的,然而,除了木质素,没有一个可以容易地及时测量用于过程控制。 本研究将证明一种新的拉曼系统的原理,和系统的化学计量学方法,允许快速的光谱数据采集和明确的光谱化学分析湿纸浆在恶劣的生产条件下。电光仪器研究将导致后向散射采样几何形状和共焦参数,再加上表达激光波长,功率和分辨率,所有选择,以最大限度地提高信息包含在签名光谱特征。该仪器系统将采用复杂的化学计量学策略,采用小波变换和模板引导的遗传算法特征选择与多元分类,从原始拉曼光谱中提取最大的分析信息。将光谱化学观察结果与纤维和最终用途纸张性能的常规表征相关联的分析程序将证明用于瞬时测定纸浆质量相对于纸张外观和强度的全面拉曼计的原理。
