Abstract
PROCEDIMIENTO PARA CONFORMAR UN PATRON DE REFLECTANCIA. COMPRENDE: A) CALENTAR UN POLIMERO ACRILICO A SU TEMPERATURA DE FUSION; B) COMBINAR AL POLIMERO ACRILICO FUNDIDO CON UN 40 POR CIEN EN PESO DE SULFATO BARICO EN POLVO; C) HOMOGENEIZAR LA COMBINACION DE B) MEDIANTE CALENTAMIENTO; D) CONFIGURAR A LA MASA HOMOGENEA EN LA FORMA DESEADA; E) DEJAR ENFRIAR LA MASA DE D) PARA OBTENER EL PATRON DE REFLECTANCIA. EL POLIMERO ACRILICO TIENE UNA TRANSMITANCIA SUPERIOR AL 90 POR CIEN DESDE 325 MM HASTA 1.000 MM PARA UNA MUESTRA DE 0,32 CM DE ESPESOR Y EL SULFATO BARICO EN FORMA DE POLVO TIENE UNA PUREZA EQUIVALENTE A LA FARMACOPEA USA Y ESTA PRESENTE EN FORMA DE PARTICULAS ESFERICAS U OBLONGAS CON UN TAMAÑO ENTRE 0,3 Y 2 MUM. SE EMPLEA PARA FABRICAR PATRONES DE REFLECTANCIAS EN DISPOSITIVOS DE MEDIDA, COLORIMETROS Y REFLECTOMETROS.
