In a papermaking process, improved drainage and retention are obtained when ionic, organic microbeads of less than about 1,000 nm in diameter if crosslinked or less about than 60 nm in diameter if noncrosslinked are added either alone or in combination with a high molecular weight organic polymer, and/or polysaccharide. Further addition of alum enhances drainage formation and retention properties in papermaking stock with and without the present of other additives used in papermaking processes.
在造纸工艺中,如果单独添加或与高分子量有机聚合物和/或
多糖一起添加交联的直径小于约 1,000 nm 或未交联的直径小于约 60 nm 的离子有机微珠,则可改善排
水和留着性能。在造纸过程中使用或不使用其他添加剂的情况下,进一步添加
明矾可增强造纸浆料的排
水形成和保持性能。
