目前,工厂一般采用过氧化氢漂白制备高白度的机械浆,但过氧化物会因过渡金属元素的诱导效应而分解。由于锰、铁和铜元素可随木材原材料以及处理过程中用水或者以漂白化学品杂质的形式进入
At present, the factory generally uses hydrogen peroxide bleaching to prepare high whiteness mechanical pulp, but the peroxide can be decomposed by the inductive effect of transition metal elements. Since manganese, iron and copper can be used as a raw material for wood as well as water used in the process or as impurities in bleaching chemicals
