木屑是木材加工过程的副产物,白度不高,限制了它在造纸中的应用。本文对木屑进行了漂白实验,通过EDTA处理和保险粉处理方式,对木屑的过氧化氢漂白进行白度提高研究,结果表明,EDTA酸处理方法具有明显优势。 Sawdust is a by-product of the wood processing process and its low whiteness limits its use in papermaking. In this paper, the bleaching experiments on sawdust were carried out. The bleaching of bleached bleached sawdust with whiteness was studied by EDTA treatment and savory powder treatment. The results showed that the method of EDTA acid treatment had obvious advantages.
