Abstract

La presente comprende un proceso para fabricacion de papel que comprende formar una lechada celulosica acuosa para fabricacion de papel, someter la lechadaa una o más etapas de corte, agregar a la lechada una carga mineral antes de por lo menos una de tales etapas de corte, agregar a la lechada después de laadicion de la carga mineral y antes de por lo menos una de las etapas de corte una cantidad efectiva de un polímero de dispersion que se selecciona del grupoque consiste de copolímeros de acrilamina y sal cuaternaria de cloruro de dimetilaminometilacrilato de metilo (DMAEA.MCQ), sal cuaternaria de cloruro dedimetilaminoetilmetacrilato de metilo (DMAEM.MCQ), sal cuaternaria de cloruro de dimetilaminoetilacrilato de bencilo (DMAEA.BCQ), ysal cuaternaria decloruro de dimetilaminoetilmetacrilato de bencilo (DMAEM.BCQ) y cloruro de dialildimetilamonio (DADMAC), someter a corte la lechada, agregar una micropartículaque se selecciona del grupo de sustancias orgánicas tales como copolímeros y ácidos poliacrílico, sustancias inorgánicas tales como bentonita y solucion desílice, escurrir la lechada para formar una hoja y secar la hoja para formar una hoja de papel.The present comprises a papermaking process comprising forming an aqueous cellulosic slurry for papermaking, submitting the grout to one or more cutting stages, adding a mineral load to the slurry before at least one such cutting stage, add to the slurry after the addition of the mineral filler and before at least one of the cutting stages an effective amount of a dispersion polymer that is selected from the group consisting of acrylamine copolymers and quaternary salt of methyl dimethylaminomethylacrylate chloride (DMAEA.MCQ), quaternary salt of methyl dedimethylaminoethyl methacrylate chloride (DMAEM.MCQ), quaternary salt of benzyl dimethylaminoethyl acrylate chloride (DMAEA.BCQ), and quaternary salt of dimethylaminoethylmethacrylamide of benzyl dimethyl dimethylmethacrylate (D-dimethylmethylmethacrylate (DMA) DADMAC), cut the slurry, add a microparticle that is selected from the group of organic substances such as copol Polyacrylic acids and polymers, inorganic substances such as bentonite and slide solution, drain the slurry to form a sheet and dry the sheet to form a sheet of paper.
