Abstract

COMPOSICIONES PARA INHIBIR LA CORROSION DE ELEMENTOS METALICOS EN CIRCUITOS DE AGUAS INDUSTRIALES. SE CARACTERIZAN PORQUE COMPRENDEN POLIMEROS DE ACIDOS ACRILICO Y/O METACRILICO Y SUS DERIVADOS, OTROS COMPUESTOS ORGANICOS DEL TIPO LIGNOSULFONATOS Y SALES INORGANICAS DE ZINC. LOS POLIMEROS DE ACIDO ACRILICO Y/O METACRILICO SON DE BAJO PESO MOLECULAR OBTENIDOS A PARTIR DE LOS ESTERES DE LOS ACIDOS O DE SUS SALES SODICA, POTASICA O AMONICA CON ALCOHOLES DE 1 A 3 ATOMOS DE CARBONO. LOS COMPUESTOS ORGANICOS DEL TIPO LIGNOSULFONADOS SON LIGNOSULFONATOS DE SODIO, POTASIO O AMONIO. LAS SALES INORGANICAS SON PREFERENTEMENTE CLORUROS Y SULFATOS DE ZINC. LA PROPORCION RELATIVA ENTRE POLIMERO ACRILICO / LIGNOSULFONATO / ZINC SON DE 12/3/8 A 16/7/10, SIENDO CON PREFERENCIA LA DE 15/5/9, 5. DICHAS COMPOSICIONES SE USAN EN AGUAS DE REFRIGERACION A CONCENTRACIONES COMPRENDIDAS ENTRE 30 A 80 MG/1. INHIBEN LA CORROSION EN LOS CIRCUITOS DE AGUAS INDUSTRIALES.
