Abstract

Composición aditiva a base de almidones aumentados para fabricarpapel, caracterizada porque comprende una suspensión de dos fases de almidón aumentado que tiene una sustancia seca desde 0.5% hasta 30% en peso, un volumen de aumento cocinado desde 1.6 ml/g hasta 100 ml/g y solubles cocinados desde 0.5% hasta 50% en peso. Proceso de elaboración de una composición aditiva para fabricar papel caracterizado porque comprende cocinar una lechada de almidón que tiene una sustancia seca desde 0.5% hasta 30% en peso, bajo condiciones de temperatura controlada desde 55°C hasta 95°C durante un tiempo suficiente para obtener una suspensión de almidón aumentado, de dos fases que tiene un volumen de aumento, cocinado desde 1.6 ml/g hasta 100 ml/g y solubles cocinados desde 0.5% hasta 50% en peso. Proceso de elaboración de una composición aditiva para fabricar papel caracterizado porque comprende cocinar una lechada de almidón que tiene una sustancia seca desde 3% hasta 8% en peso, a una temperatura ambiente desde 10°C hasta 35°C, en un proceso por baches o lotes con agitación continua bajo condiciones de pH controladas en donde el pH primero se ajusta con cáustico desde 9 hasta 13 y es mantenido a ese nivel desde 5 hasta 20 minutos, seguido por la adición de ácido para reducir el pH desde 5 hasta 9 para obtener una suspensión de almidón aumentado de dos fases que tenga un volumen de aumento cocinado desde 1.6 ml/g hasta 100 ml/g y solubles cocinados desde 0.5% hasta 59% en peso.Additive composition based on increased starches to make paper, characterized in that it comprises a two-phase suspension of increased starch having a dry substance from 0.5% to 30% by weight, a cooked increase volume from 1.6 ml / g to 100 ml / g cooked soluble from 0.5% to 50% by weight. Process of elaboration of an additive composition to make paper characterized in that it comprises cooking a starch slurry that has a dry substance from 0.5% to 30% by weight, under controlled temperature conditions from 55 ° C to 95 ° C for a sufficient time to Obtain a two-phase, increased starch suspension having an increasing volume, cooked from 1.6 ml / g to 100 ml / g and cooked soluble from 0.5% to 50% by weight. Process of elaboration of an additive composition to make paper characterized in that it comprises cooking a starch slurry that has a dry substance from 3% to 8% by weight, at an ambient temperature from 10 ° C to 35 ° C, in a pothole process or batches with continuous stirring under controlled pH conditions where the pH is first adjusted with caustic from 9 to 13 and is maintained at that level for 5 to 20 minutes, followed by the addition of acid to lower the pH from 5 to 9 to Obtain a two-phase increased starch suspension having a cooked increase volume from 1.6 ml / g to 100 ml / g and cooked soluble from 0.5% to 59% by weight.
