Abstract

SERIA DESEABLE REEMPLAZAR SOLUCIONES CON BASE DE ACIDO NITRICO PARA TRATAR ACEROS Y MATERIALES SIMILARES CON UNA SOLUCION CON BASE DE ACIDO SULFURICO QUE CONTIENE PEROXIDO DE HIDROGENO, PERO ESTAS SOLUCIONES DE REEMPLAZO PIERDEN RAPIDAMENTE EL PEROXIDO DE HIDROGENO A TRAVES PRINCIPALMENTE DE DESCOMPOSICION CAUSADA POR HIERRO. UNA SOLUCION PARA EL TRATAMIENTO DE SUPERFICIES QUE SE BASA EN ACIDO SULFURICO Y PEROXIDO DE HIDROGENO, PERO TIENE UNA ESTABILIDAD MEJORADA, CONTIENE UNA CANTIDAD EFECTIVA COMBINADA DE ACIDO HIDROFLUORICO, UN ACIDO HIDROXIBENZOICO Y N-ALCOXIFENIL-ACETAMIDA. PREFERIBLEMENTE, EL ACIDO HIDROXIBENZOICO ES ACIDO PARA-HIDROXIBENZOICO Y LA N-ALCOXIFENIL-ACETAMIDA ES N-(4 ETOXIFENIL)-ACETAMIDA. ES PREFERIBLE EMPLEAR UNA SOLUCION SATURADA DE CADA UNO DE LOS DOS ULTIMOS COMPONENTES, Y ESTO PUEDE CONSEGUIRSE PRACTICA Y SIMPLEMENTE AÑADIENDO LOS COMPONENTES SOLIDOS EN FORMA DE BLOQUE O BLOQUES QUE MANTIENEN LA SOLUCION SATURADA DURANTE UN EXTENSO PERIODO DE TIEMPO.
