本文综述了近年来国内外用镁碱代替钠碱的高得率浆和化学浆H2O2漂白的研究进展和生产实践。结果表明,采用镁碱的过氧化氢漂白可以节约生产成本,降低草酸钙结垢,减少浆料中的阴离子垃圾含量和废水的污染负荷,同时浆料可获得良好的物理和光学性能。 This review summarizes the research progress and production practice of high yield pulp and chemical pulp H2O2 bleaching using magnesium alkalis instead of sodium alkali at home and abroad. The results show that the use of magnesium hydroxide bleaching of hydrogen peroxide can save production costs, reduce calcium oxalate scale, reduce the anionic waste in the slurry and wastewater pollution load, while the slurry can obtain good physical and optical properties.
