麦草化机浆与废纸浆配抄制备瓦楞原纸

The Production of Corrugated M Medium With Wheat Straw CMP and Waste Paper Pulp as Raw Materials

探究化学助剂对麦草化机浆纸张物理强度性能的影响,并与OCC浆配抄制备瓦楞原纸。结果表明:化学助剂可以明显提高麦草化机浆纸张的物理强度性能,在0.1%CPA M/0.1%H P555联用条件下可以获得性能较优的麦草化机浆。在此基础上与废纸浆配抄(配抄比例3∶7)可以制备瓦楞原纸,其抗张指数、裂断长、耐破指数以及环压指数分别为45.47 N.m/g、4.71 km、2.72 kPa.m^(2)/g、11.58 N.m/g,达到瓦楞原纸物理强度性能的要求。该研究拓展了麦草化机浆的应用,有助于缓解瓦楞原纸原料短缺问题。

The influence of chemical additives on the physical strength of wheat straw chemical mechanical pulp(CMP)is investigated.Corrugated medium is produced with wheat straw CMP and waste paper(OCC)pulp as raw materials.The results showed that these additives significantly improved the physical strength of paper made by wheat straw CMP,which was obtained using a combination of 0.1%CPAM/0.1%HP 555.Under this condition,corrugating medium can be produced with wheat straw CMP and waste paper pulp at a ratio of 3:7,and the paper exhibits a tensile index of 45.47 N·m/g,a breaking length of 4.71 km,a tear strength index of 2.72 kPa·m^(2)/g,and a ring crushing index of 11.58 N·m/g.This study broadens the use of wheat straw CMP and alleviates the scarcity of raw materials for corrugated medium production.
