Abstract

PROCEDIMIENTO PARA FORMAR UNA BANDA FIBROSA IMPREGNADA CON RESINA TERMOENDURECIBLE. SE FORMA UNA LECHADA ACUOSA QUE COMPRENDE DEL 3 AL 95 POR 100 EN PESO DE FIBRA CELULOSICA Y DEL 5 AL 97 POR 100 EN PESO DE FIBRA DE PULPA SINTETICA POLIMERICA, CONSISTE EN LA FORMACION DE UNA DISPERSION DE UN POLIMERO EN UN DISOLVENTE Y OPCIONALMENTE UN AGENTE DISPERSANTE DE AGUA. SE DESAGUA DICHA LECHADA Y SE FORMA UNA BANDA A PARTIR DE LA MISMA. SE IMPREGNA LA BANDA CON UNA RESINA TERMOENDURECIBLE Y SE CALIENTE DICHA RESINA HASTA EL CURADO DE LA MISMA A UNA TEMPERATURA SUPERIOR AL PUNTO DE FUSION DEL ELEMENTO TERMOPLASTICO.
