Abstract

SE PREPARA UNA VARIEDAD DE CARGA DE CRISTALES DE YESO ACICULARES HIDRATANDO PARTICULAS DE SULFATO CALCICO DIHIDRATO EN UN REACTOR SEMBRADO AGITADO CONTINUAMENTE, CON UN BAJO NIVEL DE SOBRESATURACION, PARA OBTENER CRISTALES QUE TIENEN UNA RELACION ENTRE DIMENSIONES DE APROXIMADAMENTE 100:10:1 Y UNA LONGITUD MEDIA EN LA DIMENSION MAYOR DE APROXIMADAMENTE 100-450 MICROMETROS. PARA FABRICAR PAPEL, LA SUSPENSION DE CRISTALES TUBULARES OBTENIDA PUEDE AÑADIRSE DIRECTAMENTE A LA PASTA PAPELERA ANTES DE LA FORMACION DEL PAPEL CONTINUO A FIN DE OBTENER UN PAPEL CARGADO QUE TIENE ALTA RETENCION DE CARGA.
