Abstract

PROCEDIMIENTO PARA LA PREPARACION DE ESTRUCTURAS CONSTITUIDAS POR POLIMEROS SINTETICOS. SE PREPARA UNA MEZCLA DE UN POLIMERO SINTETICO FILMOGENO Y ORIENTABLE, CON UN 1-20 POR 100 EN PESO DE UN MATERIAL A BASE DE CEMENTO EN POLVO CON 0,05-0,5 POR 100 EN PESO DE UNA FUENTE EXPANDANTE O HINCHANTE. SE TRANSFORMA LA MEZCLA EN UNA PELICULA PLANA O TUBULAR. SE ORIENTA ESTA PELICULA EN DIRECCION LONGITUDINAL O PREVALENTEMENTE LONGITUDINAL MEDIANTE ESTIRADO MECANICO, CON RELACIONES DE ESTIRAJE COMPRENDIDAS ENTRE 1 : 3 Y 1 : 15, FORMANDOSE UNA PELICULA ORIENTADA QUE TIENE UN ESPESOR COMPRENDIDO ENTRE 20 Y 200 MICRAS. SE REALIZA LA FIBRILIZACION DE LA PELICULA ORIENTADA. SE UTILIZAN COMO REFUERZO EN TODO TIPO DE LIGANTES HIDRAULICOS, COMO CEMENTO PORTLAND, CEMENTOS ALUMINOSOS, CALES HIDRAULICAS Y YESOS.
