Abstract

SE REFIERE A PARTICULAS QUE CONTIENEN: i) UN NUCLEO DE PERCARBONATO DE SODIO, LAS CUALES ESTAN DE 1% A 5% EN PESO EN LA CAPA DE REVESTIMIENTO, EL CUAL SE OBTIENE MEDIANTE UN PROCESO DE CRISTALIZACION SIN AGENTE DE INTERCAMBIO DE SAL; ii) UNA CAPA DE REVESTIMIENTO LIBRE DE SULFATO, BORATO Y MAGNESIO, QUE TIENE ENTRE 30% Y 75% EN PESO DE UN CARBONATO DE METAL ALCALINO Y ENTRE 25% Y 70% EN PESO DE UN SILICATO DE METAL ALCALINO UNIFORMEMENTE DISPERSADO EN LA CAPA DE REVESTIMIENTO. ADEMAS DICHAS PARTICULAS PRESENTAN UN AVOX (OXIGENO DISPONIBLE) DE 12% A 15% EN PESO, UNA DENSIDAD VOLUMETRICA DE 0,9 g/cm3 A 1,2 g/cm3, UNA CAPTACION DE HUMEDAD DE 10 A 100 g/Kg, UN TIEMPO DE DISOLUCION DEL 90% DE 0,5 min A 3 min, UN DESGASTE DE 0,05% A 5%, UNA ESTABILIDAD TERMICA DE 0,1 A 12 µW/g, UN TAMANO MEDIO DE PARTICULA DE 500 µm A 900 µm, UNA SUPERFICIE ESPECIFICA DE 2 A 6 m2/Kg, UNA FRACCION DE PARTICULAS CON UN TAMANO DE PARTICULA SUPERIOR A 1000 µm A LO MAS 30% EN PESO. LAS PARTICULAS DE PERCARBONATO NO REVESTIDAS Y LA SOLUCION DE REVESTIMIENTO OBTENIDA SE INTRODUCEN EN UN MEZCLADOR (FUNCIONAL DESDE LA TEMPERATURA AMBIENTE HASTA 50°C), PARA DISTRIBUIR LA SOLUCION DEL REVESTIMIENTO Y OBTENER PARTICULAS REVESTIDAS HUMEDAS, LAS CUALES SE SACAN Y SE SECAN EN UN SECADOR CON AIRE CALIENTE ENTRE 50°C Y 90°C, OBTENIENDO PARTICULAS REVESTIDAS SECAS
