Abstract

Procedimiento para la obtención de absorbentes de líquidos no polares de superficies sólidas y de superficies de líquidos polares, caracterizado porque comprende añadir a agua, en un hidropulpador residuos de paneles de techos compuestos de fibras de lignocelulosa, batir dichos ingredientes para obtener una lechada uniforme que tiene una consistencia de un 2% en peso de sólidos, ajustar el pH de la lechada a 7 aproximadamente añadir de 3 a 7 % en peso, basado en el peso seco de las fibras pulpadas de cera de parafina a la lechada, ajustar el pH de la lechada a 4,5 aproximadamente para precipitar la cera sobre las fibras, formar cuerpos de configuración constante a partir de dicha lechada por medio de una máquina de moldeo de pulpa en vacío y secar dichos cuerpos.
