| 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。 |
| Abstract: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. |
