Abstract

SE HA DESCUBIERTO QUE LOS POLIMEROS DE POCO PESO MOLECULAR QUE CONTIENEN ACIDO HIDROXAMICO SON UNOS INHIBIDORES EXCELENTES DE LA CORROSION PARA ALEACIONES DE HIERRO Y ACERO EN CONTACTO CON AGUAS INDUSTRIALES. CUANDO LAS AGUAS CONTIENEN IONES DE DUREZA, TALES COMO CALCIO, MAGNESIO Y MEZCLAS DE LOS MISMOS, LAS AGUAS SE TRATAN PREFERENTEMENTE CON COMBINACIONES LOS POLIMEROS QUE CONTIENEN ACIDO HIDROXAMICO Y POLIMEROS INHIBIDORES/DISPERSANTES DE ESCALA, CUYOS POLIMEROS NO CONTIENEN GRUPOS FUNCIONALES DE ACIDO HIDROXAMICO. LOS POLIMEROS QUE CONTIENEN ACIDO HIDROXAMICO, ASI COMO LA COMBINACION DE POLIMEROS DE ACIDO HIDROXAMICO Y E INHIBIDORES/DISPERSANTES DE ESCALA SE PUEDEN FORMULAR CON OTROS INHIBIDORES DE LA CORROSION.
