Study of On-line Measurement of Acidic Magnesium Sulfite Pulp Kappa Number with Spectrometry 酸性亚硫酸镁纸浆卡伯值的光学法在线测量机理的研究
Fe ( II) and Fe ( III) can be stabilized by sodium silicate and magnesium sulfite. The effect of stabilizing Fe ( II) is further better than that of stabilizing Fe ( III). 硅酸钠和硫酸镁对Fe(Ⅱ)的稳定作用要明显好于对Fe(Ⅲ)的稳定作用。
This paper mainly studies on the influence of xylanase treatment on the acidic hydrogen peroxide bleaching of magnesium based sulfite bamboo/ bagasse pulp and its optimum position in the sequence. 本文主要研究木聚糖酶处理对亚硫酸镁盐竹子/蔗渣浆酸性过氧化氢漂白的效果及其在流程中的最佳位置。
Magnesium oxide as a protector for oxygen bleaching of magnesium-based sulfite pulp 氧化镁作亚硫酸镁盐浆氧漂的保护剂
With increase of TP concentration, reaction temperature or decrease of pH value, magnesium sulfite oxidation rate decreased significantly, while the addition of magnesium sulfite and air flow rate have no obvious effect on the oxidation reaction rate. 随着茶多酚浓度的增加,反应温度的降低或pH值的升高,亚硫酸镁的氧化速率显著下降,而亚硫酸镁的加入量和空气流量对亚硫酸镁的氧化反应速率基本没有影响。
