Abstract

UNA CUBIERTA POLIMERA CON UNA SUPERFICIE TEXTURADA (ACABADO MATE) SE FABRICA POR INMERSION DE UNA FORMA, QUE TIENE PERFILES EXTERNOS CONFORMANDO A LA FORMA DESEADA DE LA CUBIERTA, EN UNA DISOLUCION DE UN POLIMERO DISUELTO EN UN LIQUIDO, EXTRACCION DE LA FORMA DE LA DISOLUCION PARA CONSERVAR LA DISOLUCION COMO UNA PELICULA SOBRE LA SUPERFICIE EXTERIOR DE LA FORMA, APLICACION DE UN SEGUNDO LIQUIDO SOBRE LA SUPERFICIE DE LA PELICULA, SIENDO EL SEGUNDO LIQUIDO INMISCIBLE CON EL PRIMERO, Y EN EL QUE EL POLIMERO ES INSOLUBLE, Y LUEGO SOLIDIFICACION DEL POLIMERO A UNA PELICULA SOLIDA, PREFERIBLEMENTE POR EVAPORACION DEL DISOLVENTE. LA APLICACION DEL SEGUNDO LIQUIDO ANTES DE COMPLETAR EL SECADO DE LA PELICULA DE POLIMERO HACE QUE LA PELICULA RESULTANTE TENGA UN ACABADO MATE, QUE TIENE EFECTO LUBRICANTE SIN NECESIDAD DE AÑADIR POLVOS O LIQUIDOS LUBRICANTES, EN ESPECIAL CUANDO SE COMBINA CON UNA BOQUILLA QUE COMUNICA UN ACABADO DE SUPERFICIE SIMILAR AL INTERIOR DE LA PELICULA.
