Abstract

PROCESO DE FABRICACION DEL PAPEL QUE DA RESISTENCIA HUMEDA DE MANERA NO CONTAMINANTE A PARTIR DE REDES IONICAS. EL PROCESO SE CARACTERIZA EN QUE SE AÑADE SUCESIVAMENTE A LA COMPOSICION FIBROSA UN POLIELECTROLITO CATIONICO Y A CONTINUACION UN POLIELECTROLITO ANIONICO SULFONADO, POR EJEMPLO EL COPOLIMERO DE ACRILAMIDA Y DE CLORURO DE ACRILOXIETILMEILAMONIO Y EL COPOLIMERO DE ACRILAMIDA Y DE 2-ACRILAMIDO-2-MTILPROPANO SULFONATO. SE UTILIZA ESTOS POLIELECTROILROS A RAZON 0.02 A 2,5% EN PESO RESPECTO DE LA MASA EN PESO SECO DE LA COMPOSICION CELULOSICA QUE ENTRA EN CAJA DE CABEZA. ESTE PROCESO ES NO CONTAMINANTE; NO PRODUCE AOX, N FORMALDEHIDO NI EPICLORIDRINA Y EL PAPEL FORMADO ES FACILMENTE REPULPABLE.
