研究了铜离子对蔗渣浆和麦草浆过氧化氢漂白的影响。研究结果表明 ,随着Cu2 + 含量的增加 ,过氧化氢漂白浆的白度、粘度和强度均降低。因此 ,过氧化氢漂白前 ,有效地控制浆中Cu2 + 含量是非常必要的。
The effects of copper ions on hydrogen peroxide bleaching of bagasse pulp and wheat straw pulp were studied. The results showed that with the increase of Cu2 + content, the whiteness, viscosity and strength of hydrogen peroxide bleached pulp decreased. Therefore, before hydrogen peroxide bleaching, it is very necessary to effectively control the Cu2 + content in the pulp.
