Abstract

METODO MEJORADO PARA REVESTIR UN CATODO CONDUCTOR DE LA ELECTRICIDAD. COMPRENDE: A) HACER PASAR UNA CORRIENTE CON UN VOLTAJE ENTRE 50 Y 500 VOLTIOS Y CON UNA DENSIDAD DE CORRIENTE ENTRE 5,4 Y 54 AMP/M POR EL ANODO CONDUCTOR, Y EL CATODO CONDUCTOR, SUMERGIDOS EN UN BAÑO DE ELECTRODEPOSICION, PARA REVESTIR AL CATODO CON UNA PELICULA AISLANTE; Y B) COCER AL REVESTIMIENTO ENTRE 90 Y 260JC DURANTE 1 A 40 MIN, PARA CURARLO. EL CATODO SE ELIGE ENTRE ACERO, COBRE, MAGNESIO Y ALUMINIO Y EL BAÑO DE ELECTROCOMPOSICION O COMPOSICION CATIONICA ESTA FORMADO POR UNA SUSPENSION DE AGUA DE: UNA RESINA FORMADORA DE PELICULA QUE LLEVA RESINAS CON GRUPOS DE SALES DE AMINA, O GRUPOS DE AMONIO CUATERNATIOS; MATERIALES QUE CONTIENEN FORMALDEHIDO Y QUE SON CAPACES DE GENERAR FORMALDEHIDO LIBRE QUE DESCIENDE EL PH DEL MEDIO COMO AMINOPLASTICOS (MELAMINA O ETILENUREA) O FENOPLASTICOS (POLIMETILOLFENOLES); DISOLVENTES COALESCENTES COMO HIDROCARBUROS O ALCOHOLES; PIGMENTOS (AMARILLO DE CD, ORUJO DE CR); AGENTES TENSIOACTIVOS, HUMECTANTES Y ELIMINADORES DE FORMALDEHIDO QUE ELIMINAN AL FORMALDEHIDO Y ESTABILIZAN EL PH Y SE ELIGEN ENTRE MELAMINA, FENILUREA. SE UTILIZA EN EL SECTOR AUTOMOCION (AUTOMOVIL).
