Abstract

EL OBJETIVO DE LA INVENCION ES LA UTILIZACION DEL PROCESO PARA LA APLICACION EN ESTADO FUNDIDO DE UN AGENTE DE RECUBRIMIENTO QUE ES SOLIDO A TEMPERATURA AMBIENTE EN SOLIDOS FINAMENTE DIVIDIDOS, EN LOS QUE EL MATERIAL SOLIDO FINAMENTE DIVIDIDO ES CENTRIFUGADO EN UNA CORRIENTE CONTINUA A TRAVES DE UNA REGION DE NIEBLA DE ROCIADO GENERADA DE FORMA HOMOGENEA CONTINUAMENTE DEL AGENTE DE RECUBRIMIENTO FUNDIDO PARA EL ENCERRADO NO ACUOSO DEL PERCARBONATO SODICO SOLIDO CON UNA CASCARA HIDROFOBICA PROTECTORA DEL MATERIAL DE RECUBRIMIENTO QUE ES SOLIDO A TEMPERATURA AMBIENTE. EL MATERIAL RECIEN RECUBIERTO ES TRANSPORTADO EN UN FLUJO DE GAS REFRIGERANTE PASADO DE FORMA PREFERENTE EN AIRE/NITROGENO LIQUIDO. EL OBJETIVO DE LA INVENCION COMPRENDE TAMBIEN EL POLVO DE PERCARBONATO DE SODIO ENCAPSULADO EN UNA CAPA SIMPLE O MULTIPLE DE RECUBRIMIENTO PROTECTORA, CON LO CUAL EN EL CASO DE RECUBRIMIENTO DE MULTICAPA, AL MENOS LA CAPA EN CONTACTO DIRECTO CON EL PERCARBONATO DE SODIO SE APLICA MEDIANTE EL PROCESODE LA INVENCION.
