Abstract

a presente invenção refere-se a métodos para inibir a corrosão em sistemas de água de baixa dureza. o tratamento inibidor da corrosão compreende: sais de cálcio de ácidos carboxílicos de polímeros de baixo peso molecular. esses sais de cálcio podem ser adicionados pré-formados ao sistema de água necessitado de tratamento ou podem ser formados in situ no sistema. este método de inibição da corrosão não é uma fonte de fósforo de adição ou metais pesados ao sistema tratado.
