摘要
介绍了新闻纸中TMP在回用时受回用次数的影响。回用次数增加时,TMP的总电荷会增加,氧/碳比率会增加,纸页密度会增加和抽出物含量会降低,但纸页粗糙度会有所增加,抗张指数等强度指数都会有所下降。
The changes of the characteristics of TMP in ONP during paper recycling were introduced in this paper.The research results were that in spite of an increased total charge ,increased oxygen to carbon ratio,decreased extractives and an increased sheet density caused by recycling ,the paper sheet shows an increased surface roughness and a small decrease in the tensile and other indexes.
