摘要
在实验条件下,从灰分与纤维组成等方面对不同废纸进行了比较分析,研究了不同废纸脱墨浆的光学性能、油墨含量、物理强度性能等。研究发现,不含机械浆纸的白度高,其成浆残余油墨最低,尘埃少,强度相对要好,能满足配抄白度为85%文化纸生产要求。含机械浆纸脱墨制浆得率高,制浆成本低,但因其脱墨浆固有的低白度、高尘埃,无法满足高比例脱墨浆配抄文化纸生产的要求。
The ash content and fiber components of the waste papers from different sources were compared in the laboratory,the optical properties,ink contents,physical strength properties and pulping yields of the de-inked pulps from the waste papers were studied.The investigation results showed that the waste paper of wood-free grade with high brightness has the lowest ERIC content,fewer dirt,and relatively higher strength,which satisfy the production requirement for fine paper with 85%ISO brightness.Whereas the waste paper of wood-containing grade has higher pulping yield,lower pulping cost,but its low brightness and high dirt properties were unable to meet the production requirements of fine paper when using at a high proportion.
