Abstract

UN ELEMENTO DE DENSIDAD (12) PARA SU UTILIZACION EN GRASA DERIVADAS DE RUMIANTES (10) QUE SE FABRICA POR SINTERIZACION PARCIAL, DE TAL MANERA QUE SE FRAGMENTE AL ENTRAR EN CONTACTO CON LAS DISTINTAS PIEZAS DE UNA MAQUINA DE CLASIFICACION DE GRASAS, SIN PERJUDICAR A LAS PALETAS. LOS ELEMENTOS DE DENSIDAD (12) TIENEN UNA DENSIDAD DE AL MENOS 1,5 GM/CM ELEVADO 3 Y UNA RESISTENCIA TRANSVERSAL DE RUPTURA MAYOR QUE 3,000 PSI (210 KG/CM (AL CUADRADO) ) Y NO MAYOR QUE 30.000 PSI (2.120 KG/CM (AL CUADRADO) ). LA SINTERIZACION SE REALIZA BAJO CONDICIONES QUE NO PERMITEN QUE SE OBTENGAN FUERTES ENLACES DE SOLDADURA Y QUE PUEDAN SER TRATADOS MEDIANTE CALOR O IMPREGNADOS CON UN MATERIAL HIDROFOBICO INERTE PARA INCREMENTAR LA RESISTENCIA A LA CORROSION.
