【摘要】 研究了美国旧瓦楞纸箱（ＡｍｅｒｉｃａｎＯｌｄＣｏｒｕｇａｔｅｄＣｏｎｔａｉｎｅｒ）的漂白。结果表明：美国旧瓦楞纸箱经碱蒸煮预处理后，采用合适的漂白程序如Ｏ１ＰｘａＯ２ＤＰ，其最终漂白浆白度可达８０％ＩＳＯ左右。碱蒸煮预处理的浆料，具有较高的可漂性。浆料可漂性的提高，可为其应用范围开拓更广的前景。更多还原

【Abstract】 Bleaching of pulp from old corrugated container imported from U.S.A was conducted. The results show that alkaline digesting pretreatment of OCC pulp and O 1PxaO 2PP bleaching sequence can lead to the brightness of 80%ISO(Pxa Peroxy acid stage). Alkali digestion of OCC renders the pulp to be more readily bleached. In this way, employment of OCC as a large fibre furnish in bleached paper grades will be possible.更多还原
