Abstract

SE PREPARAN COMPOSICIONES DETERGENTES GRANULARES POR FORMACION DE UNA PASTA ACUOSA QUE CONTIENE TRIPOLIFOSFATO, PIROFOSFATO Y/O SILICATO, OTRAS SALES NEUTRAS O ALCALINAS Y TENSIOACTIVO DETERGENTE OPCIONAL, SECADO POR PULVERIZACION DE LA PASTA EN UNA TORRE DE PULVERIZACION A GRANULOS PARCIALMENTE SECOS Y LUEGO COMPLETAR EL SECADO DE LOS GRANULOS EN UN SECADERO SECUNDARIO. DURANTE EL PROCESO DE SECADO LA TEMPERATURA DE LOS GRANULOS NO EXCEDE DE 90 (GRADOS) C APROXIMADAMENTE PARA HACER MINIMA LA REVERSION DEL POLIFOSFATO Y LA FORMACION DE SILICATOS INSOLUBLES. LOS GRANULOS RESULTANTES TIENEN PROPIEDADES FISICAS MEJORADAS FRENTE A LOS GRANULOS SECADOS POR PULVERIZACION CONVENCIONAL QUE TIENEN EL MISMO CONTENIDO EN AGUA, O PROPIEDADES FISICAS SIMILARES A NIVELES DE HUMEDAD MAYORES
