Abstract

PARA LA DEGRADACION ENZIMATICA DE LA RESINA PRESENTE EN LA PASTA DE CELULOSA ESPONJOSA QUIMIOTERMOMECANICA (CTMP-ESPONJOSA) MEDIANTE UNA HIDROLISIS DE LOS TRIGLICERIDOS PRESENTES EN LA RESINA A ACIDOS GRASOS FACILMENTE ELIMINABLES DE LA PASTA, SE UTILIZA UNA LIPASA SEPARADORA DE LA GRASA, CON EL FIN DE MEJORAR LA ABSORBENCIA A LOS LIQUIDOS DE LA PASTA ESPONJOSA CUANDO A PARTIR DE DICHA PASTA SE FORMAN ARTICULOS SANITARIOS TALES COMO PAPEL SUAVE, PAÑALES DESECHABLES O SIMILARES. LA LIPASA SE SUMINISTRA BIEN A UNA PASTA CTMP O A TROCITOS DE CARTON DESTINADOS A UN PROCESO DE CTMP.
