本刊讯:青岛科技大学化工学院陈夫山等人用硝酸镁、氯化镁、硫酸镁取代部分玉米淀粉对瓦楞原纸进行表面施胶,探讨无机盐的添加对瓦楞原纸物理强度及其他性能的影响。结果表明,当淀粉与无机盐的用量比(质量比)为8:2、施胶量为6g.m-2时,相对于施胶前纸样,硝酸镁、氯化镁、硫酸替代部分淀粉施胶 Journal: Qingdao University of Science and Technology, Institute of Chemical Technology Chen Fushan, who replaced part of the corn starch with magnesium nitrate, magnesium chloride, magnesium sulfate on the surface of corrugated paper sizing, inorganic salt on the physical strength of corrugated paper and other properties. The results showed that when the ratio of starch to inorganic salt (mass ratio) was 8: 2 and the sizing amount was 6g.m-2, magnesium nitrate, magnesium chloride and sulfuric acid were substituted for part of the starch sizing
