Optimización del proceso de dispersión y blanqueo oxidativo para la elaboración de papel TISSUE en Familia Sancela del Ecuador S.A

Abstract

The Optimization of Dispersal and Whitening Oxidative Process was realized in the production of tissue paper in Sancela Family of Ecuador S.A. located in the sector of Lasso, Cotopaxi province. The random systematical experimental method was used for the initial characterization of the processes, taking pasta samples in strategic points, for 8 days, to the received samples were realized tests of quality control established by the company using volumetric and instrumental skills, in the Process laboratory and Quality of the company. The initial characterization demonstrated that the ink point are 119,24 ppm (standard 150 máx.), whiteness 86,18° ISO (standard 95±5), by means the Statgraphics program the ideal parameters are established to minimize ink and whiteness the variability points of, which are implemented by a period of one week a whiteness of 88,14°ISO being obtained ink points 108,03 ppm; based on internal specification of the company mentioned to the Norm TAPPI T 452:2002 for whiteness and Norm TAPPI T 213 for ink points. This work concludes that the ideal parameters for the whitening oxidative are: temperatura of 70°C; 0,4 of parameter of alkalinity, 60 min residence time, consistency of 15%; for the dispersión it closed teeth of compression cone to increase the consistency in the kneader. It is recomended to apply the study at Sancela Family company of Ecuador and controlling the parameters every day, allowing a better quality of varaiables and attibutes the paper, and to offer to the consumers a quality product.
