摘要：碱性亚钠－碱性过氧化氢及碱性过氧化氢（Ⅰ）－碱性过氧化氢（Ⅱ）两段化学预浸渍，常压磨浆，段间漂白，直接制取杨木漂白化机浆。结果表明：（１）用碱性亚钠－碱性过氧化氢浸渍，段间漂白，可制得得率为８６％ＢＣＭＰ。白度较相同条件常规ＢＣＭＰ低１％～４％ＩＳＯ，强度高８％～１８％；（２）用３．６％ＮａＯＨ，４％Ｈ＿２Ｏ＿２两段过氧化氢常压预浸渍，可制得得率为９０％以上，白度７２．７％ＩＳＯＢＣＭＰ，惟强度指标较碱性亚钠－碱性过氧化氢浸渍段间漂白所得ＢＣＭＰ略低。
Bleached CMP pulps can be obtained by normal CMP pulping procedure. Two chemical combi-nations as alkaline sodium sulphite-alkaline peroxide,alkaline peroxide-alkaline peroxide for two stage pre-treatment of wood chips,atmosferic refining,were investigated.The result shows that, under alkalinesodium sulphite-alkaline peroxide two stage impregnations, bleached CMP can be produced with yield of86%,strength of more 8%～18%and brightness of 1%～4%which are less than normal BCMP;underalkaline peroxide two stage impregnations,BCMP pulps were produced in yield of more than 90%,bright-ness of 72% ISO,but the pulp strength were a little lower than the first pulps.
