Abstract

Blanqueo de pulpa químicas de bagazo utilizando peróxido de Hidrógeno. El trabajo se relaciona con el desarrollo de la industria papelera y consiste en la obtención de pulpa blanca de bagazo de alta calidad utilizando el Peróxido de Hidrógeno en consecuencia de blanqueo químico. Se ha comprobado su efectividad como agente de blanqueo químico de pulpa de madera, en las etapas finales del blanqueo fundamentalmente para estabilizar la brillantez ya alcanzada. En el caso del bagazo no existe ningún antecedente de su aplicación y los trabajos ejecutados por los autores que suscriben esta solicitud han demostrado que la utilización del Peróxido de Hidrógeno en el blanqueo de Pulpas Químicas de Bagazo permite no solo estabilizar la brillantez final sino actuar como un agente de blanqueo elevando considerablemente la brillantes a lo cual se adiciona la simplificación que conlleva en la tecnología de blanqueo, al disminuir el número de etapas necesarias y los tiempos de retención para obtener calidad de pulpa blanca.Bagasse chemical pulp bleaching using hydrogen peroxide. The work is related to the development of the paper industry and consists of obtaining high quality white bagasse pulp using Hydrogen Peroxide as a consequence of chemical bleaching. Its effectiveness as a chemical bleaching agent for wood pulp has been proven in the final stages of bleaching, mainly to stabilize the brilliance already achieved. In the case of bagasse, there is no history of its application and the work carried out by the authors who subscribe to this application has shown that the use of Hydrogen Peroxide in the bleaching of Chemical Bagasse Pulps allows not only to stabilize the final brilliance but also to act as a bleaching agent considerably increasing the brilliance to which is added the simplification involved in bleaching technology, by reducing the number of steps necessary and the retention times to obtain quality white pulp.
