Abstract
UN PROCEDIMIENTO PARA SECAR PARTICULAS HUMEDAS DE UN MATERIAL POLIMERO. CUANDO SE HA INTENTADO SECAR PARTICULAS POLIMERAS HUMEDAS EN AIRE CALIENTE HASTA 110GC, SE HA TENDIDO A PRODUCIR UN DESCOLORAMIENTO EN EL PRODUCTO, A INTRODUCIR AGLOMERADOS EN EL PRODUCTO, A REDUCIR LA DISPERSABILIDAD DEL PRODUCTO Y A REDUCIR LA INTEGRIDAD DE LA SUPERFICIE DE LAS PARTICULAS. SE HA DESARROLLADO AHORA UN PROCEDIMIENTO DE SECADO, QUE COMPRENDE CALENTAR HASTA UNA TEMPERATURA ELEVADA LAS PARTICULAS HUMEDAS EN UNA ATMOSFERA ESENCIALMENTE EXENTA DE GAS OXIGENO, DE TAL MANERA QUE EN ESENCIA TODA LA HUMEDAD SE ELIMINA DE LA ASOCIACION CON DICHAS PARTICULAS, Y EN CONDICIONES DE TIEMPO Y TEMPERATURA TALES QUE SE MINIMIZA CUALQUIER DETERIORO SUSTANCIAL DE DICHAS PARTICULAS. PREFERIBLEMENTE, LA ATMOSFERA ES DE NITROGENO.
