Abstract

SE EXPONE UN PROCEDIMIENTO PARA PULIR ARTICULOS QUE CONSTAN DE MATERIALES ACRILICOS BLANDOS. EL PROCEDIMIENTO INCLUYE UNA ETAPA DE PULIDO CRIOGENICO Y UNA ETAPA DE LIMPIEZA. EN LA ETAPA DE PULIDO, SE CARGA UN RECIPIENTE CON BOLAS PARA PULIR DE VARIOS TAMAÑOS, BICARBONATO SODICO, UN AGENTE HINCHANTE Y LOS ARTICULOS A PULIR, DURANTE UN PERIODO DE TIEMPO Y CON UNA VELOCIDAD DE ROTACION, SUFICIENTE PARA QUITAR LAS IRREGULARIDADES SUPERFICIALES. A CONTINUACION DE LA ETAPA DE PULIDO, SE CARGA UN RECIPIENTE CON (A) UNA SUSPENSION LIMPIADORA QUE CONSTA DE BOLAS LIMPIADORAS DE VARIOS TAMAÑOS E (I) HIDROXIDO SODICO Y AGUA O (II) ALUMINA, UN AGENTE TENSOACTIVO Y UN DISOLVENTE, Y (B) LOS ARTICULOS A LIMPIAR, DURANTE UN PERIODO DE TIEMPO Y CON UNA VELOCIDAD DE ROTACION, SUFICIENTE PARA LIMPIAR LA SUPERFICIE DE LOS ARTICULOS PULIDOS. SE LLEVA A CABO PREFERENTEMENTE LA AGITACION MEDIANTE UNA MAQUINA DE TAMBOR GIRATORIO.
