非木材类纸浆

Abstract

本发明提供一种非木材类纸浆,其为以草本植物材料的三素分离得到的纤维素产品。其中该纤维素产品的性质如下:基于纤维素产品的总重量纤维素的浓度为25%?30%,K值为5.5以下,叩解度为20?30°SR,湿重为2?3.5g,白度为44.5°以下,pH值为7?9,基于固形物总重量的纤维素含量为90%?97%。本发明非木材类纸浆与同类型产品相比具有更高的纤维素含量,制得的纸具有更加优异的外观特征。此外,使用本发明的非木材类纸浆制造纸时没有添加化学药剂,可不经过漂白处理,因此无残留,使用时对人体没有伤害。
The invention provides non-wood type paper pulp, which is a cellulose product prepared through three-element separation of a herbaceous plant material. The cellulose product has the properties that the concentration of total weight cellulose based on the cellulose product is 25-30 percent; a K value is below 5.5; a beating degree is 20-30 degrees SR; the wet weight is 2-3.5g; the whiteness is below 44.5 degrees; the pH value is 7-9; the cellulose content based on total solid weight is 90-97 percent. Compared with products of the same kind, the non-wood type paper pulp has higher cellulose content; prepared paper has more superior appearance features. Moreover, no chemical agent is added and bleaching treatment can be omitted when the non-wood type paper pulp is used for making paper, so that residues are avoided, and the non-wood type paper pulp is harmless to human body during use.
