Abstract
UN PROCESO MEJORADO PARA LA PRODUCCION DE UN PLASTIFICANTE MEZCLA FLUIBLE DE RESINA DE ALCOHOL POLIVINILO (PVA) CAPAZ DE TRATAMIENTO TERMOPLASTICO. EL PROCESO SIRVE PARA LA INCORPORACION DE PLASTIFICANTES EN, UN CONTACTO INTIMO CON LA RESINA PVA SIN ETAPAS DE CALENTAMIENTO, ENFRIAMIENTO O SECADO EXTENDIDO. ESPECIFICAMENTE, LOS GRANULOS DE RESINA PVA CON UNA DISTRIBUCION DE TAMAÑO DE PARTICULAS APROPIADAMENTE PEQUEÑA SON RECUBIERTOS POR PULVERIZACION CON UN MEDIO PLASTIFICANTE LIQUIDO Y ENTONCES SE MEZCLAN CON UNMEDIO DE RECUBRIMIENTO DE POLVO FINO SECO PARA PRODUCIR UNA MEZCLA DE PVA PLASTIFICADA SECA FLUIBLE. COMPONENTES ADICIONALES, TALES ANTIBLOQUEO PUEDEN TAMBIEN SER INCORPORADOS AL PRODUCTO ACABADO.
