Title:
繊維材料懸濁液に填料を負荷するための方法
Document Type and Number:
Japanese Patent JP2009541604
Kind Code:
A
Abstract:
A process to load a fibrous slurry with a filler, in particular with calcium carbonate (fiber loading). The loaded fibrous slurry is divided into at least two fractions, a light fraction and a heavy fraction, for which purpose hydrocyclones are used in one embodiment. In this case, the different fractions have a different level of loading, that is to say the quantity of precipitated fillers adhering to the fibers is different in each case. There is the possibility of feeding the less highly loaded fibers back into the loading process, in order to increase the level of loading of this fraction further.
