IN-LINE PRODUCTION METHOD FOR PAPER MAKING PROCESS

摘要

An in-line production method for providing a liquid flow of at least one additive in the short circulation and into the liquid flow of a paper making stock of a fiber web machine by feeding, the liquid flow of the at least one additive to the liquid flow of the short circulation, wherein a suitable amount of a microfibrillated cellulose or nanofibrillated polysaccharide is provided substantially simultaneously with the feeding of liquid flow of the at least one additive.

主权项

1. An in-line production method for providing a liquid flow of two or more additives in a liquid flow of a short circulation and into a liquid flow of a paper making stock of a fiber web machine by feeding the liquid flow of the additives to the liquid flow of the short circulation, wherein the method further comprises allowing these to react with one another, wherein the method comprises crystallizing a filler, and wherein the additives are carbon dioxide and lime milk, said carbon dioxide and lime milk being fed to the short circulation
whereina suitable amount of a microfibrillated cellulose or nanofibrillated polysaccharide is provided substantially simultaneously with the feeding of the liquid flow of the at least two additives, such that the additives reacts or start nucleation onto the surface of cellulose or precipitate on the surface of the microfibrillated cellulose and thereby form complexes with the microfibrillated cellulose or nanofibrillated polysaccharide.
