Abstract

ESTA ESPECIFICACION DESCRIBE UN PROCESO PARA PRODUCIR POLVOS CARGADOS CON LIQUIDO QUE SON CAPACES DE SOLTAR SU CARGA LIQUIDA CUANDO SE VEN SUJETOS A FUERZAS DE CORTE. SE DISUELVEN UN POLIMERO CELULOSICO Y UNA CARGA LIQUIDA EN UN DISOLVENTE POLAR PARA FORMAR UNA DISOLUCION. LUEGO, EL DISOLVENTE SE EVAPORA DE FORMA DISPERSIONANTE DE LA DISOLUCION PARA FORMAR UN POLVO CARGADO DE LIQUIDO. SE DESCRIBE LA EVAPORACION DISPERSIONANTE DEL DISOLVENTE EN UNA TORRE DE SECADO DE PULVERIZACION. LOS POLIMEROS CELULOSICOS EJEMPLIFICADOS EN LA ESPECIFICACION INCLUYEN TRIACETATO DE CELULOSA, UNA CELULOSA DE ETILO Y UN PROPIONATO DE CELULOSA. LOS DISOLVENTES EJEMPLIFICADOS INCLUYEN CLORURO DE METILENO, ACETATO DE ETILO Y ACETONA. LOS USOS DEL POLVO CARGADO DE LIQUIDO DESCRITO INCLUYEN UN PORTADOR PARA FRAGANCIAS USADO EN UNA FORMULACION DE JABON DE BAÑO, UNA FORMULACION DE PROTECTOR SOLAR EN FORMA DE POLVO, UN REPELENTE DE INSECTOS EN FORMA DE POLVO Y UN ACEITE PARA NIÑOS Y UN HUMEDECEDOR EN FORMA DE POLVO .
