摘要： Paper is made by providing an anionic aqueous emulsion of a size, usually a reactive anhydride size, and mixing it into a cellulosic suspension prior to drainage of the suspension to form a sheet which is then dried to provide paper (including paper board). The emulsion is preferably stabilised wholly or mainly by 0.5 to 30 parts by weight (per part by weight size) of water soluble, anionic, polymeric stabiliser, which is preferably anionic starch. Alternatively, the emulsion may be added to the cellulosic suspension while it is anionic, before mixing retention into it. The emulsion may be added to the cellulosic suspension after cationic retention aid has been added to it, the emulsion being added with, before or after mixing anionic microparticulate material or other anionic bridging aid, prior to drainage of the suspension.
摘要翻译：纸通过提供尺寸（通常为反应性酸酐尺寸）的阴离子水性乳液制成，并在悬浮液排出之前将其混合到纤维素悬浮液中以形成片材，然后干燥以提供纸张（包括纸板）。乳液优选完全或主要稳定为水溶性阴离子聚合物稳定剂0.5-30重量份（按重量份计），其优选为阴离子淀粉。或者，可以将乳液在阴离子之前加入到纤维素悬浮液中，然后将保留物混入其中。在向其中加入阳离子助留剂之后，可以将乳液加入到纤维素悬浮液中，在混合阴离子微粒材料或其它阴离子桥联助剂之前或之后，将乳液加入到悬浮液排出之前。
