摘要:
制备纸或类似物的方法,其中在最后剪切步骤之后和在流浆箱之前将由聚丙烯酰胺组成的阳离子聚合物微粒和细粒无机组分加入纸浆,接着使纸浆进行脱水以形成纸张且所述纸张进行干燥,在紧邻流浆箱之前额外加入由线性阳离子聚合物和线性阴离子共聚物组成且其整体离子性为阴离子的聚合物混合物。
摘要(英):
The invention relates to a method for producing paper or the like, wherein cationic polymer microparticles composed of polyacrylamide and a fine-particle, inorganic component are added to the paper material after the last shearing step and before the headbox, whereupon the paper material is subjected to drainage in order to form sheets and the sheets are subjected to drying. In addition, a polymer mixture, which is composed of a linear, cationic polymer and a linear, anionic copolymer, and the overall ionicity of which is anionic, is added immediately before the headbox.
