Abstract

PARA SECAR POLIMERIZADOS DE ESTIROL EXPANDIBLES DE UN TAMAÑO DE PARTICULA DE 0,02 A 0,3 MM SE LIBERAN LOS POLIMERIZADOS EN PERLAS PRESENTES EN EL AGUA COMO SUSPENSION DE LA CANTIDAD PRINCIPAL DE LA MISMA Y A CONTINUACION SE EXPONEN A LA ACCION DE UN MEDIO GASEOSO. EL SECADO TIENE LUGAR EN DOS ETAPAS, TRANSPORTANDO EL POLIMERIZADO EN PERLAS CONJUNTAMENTE CON UNA PRIMERA CORRIENTE DE GAS CALENTADA A UNA TEMPERATURA DE UNOS 45 (GRADOS) C HASTA 120 (GRADOS) C A TRAVES DE UN SECADOR POR SUSPENSION, SIENDO LA RELACION ENTRE GAS Y POLIMERIZADO EN PERLAS DE 2 A 40 KG/KG, SEPARANDO EL POLIMERIZADO EN PERLAS DE LA PRIMERA CORRIENTE DE GAS E INMEDIATAMENTE DESPUES SE DIRIGE A UN LECHO FLUIDIZADO Y QUE CON AYUDA DE UNA SEGUNDA CORRIENTE DE GAS ES TRATADO A UNA TEMPERATURA DE UNOS 0 (GRADOS) C HASTA 75 (GRADOS) C. LOS POLIMERIZADOS DE ESTIROL OBTENIDOS DE ESTA FORMA SE PUEDEN PULVERIZAR Y ESPUMAR SIN PROBLEMAS EN APARAMENTAS DE PREESPUMADO USUALES EN EL COMERCIO. ENCUENTRAN APLICACION, ENTRE OTROS, EN LA INDUSTRIA DE LA CONSTRUCCION, P. EJ. COMO ADITIVO PARA ENLUCIDOS INSONORIZANTES.
