Abstract

PROCEDIMIENTO PARA LA FABRICACION DE CARTON DE REVESTIMIENTO. SE IMPREGNA EL CARTON DE REVESTIMIENTO CON UNA EMULSION ACUOSA DE UNA RESINA TERMOENDURECIBLE PARA PENETRACION PROFUNDA DE DICHA RESINA EN EL CARTON DE REVESTIMIENTO, APLICANDOSE DICHA EMULSION ACUOSA EN UNA CANTIDAD SUFICIENTE PARA PROPORCIONAR HASTA UN 15% EN PESO DE SOLIDOS DE RESINA EN DICHO CARTON DE REVESTIMIENTO. SE SECA EL CARTON DE REVESTIMIENTO IMPREGNADO CON LA RESINA Y SE CURA SUBSTANCIALMENTE DICHA RESINA.
