【Abstract】 In this article, the methods of preparing urea peroxide and reusing mother liquor were studied. Process parameters such as concentration of urea peroxide, bleaching time and pH value were approached. Urea peroxide as a new kind of bleaching agent features high efficiency and no corrosion. Simple operation, short bleaching cycle and reusing liquor enable low energy consumption and production cost. Product quality after bleaching meets relevant standards.更多还原
