Abstract

Изобретение относится к способу обработки железобетонной конструкции со стальной арматурой с пропиткой ее катионами ингибитора для предотвращения коррозии стальной арматуры. Конструкция (1) со стальной арматурой, на которую подается водный раствор ингибитора (8), дополнительно защищается от повреждения пропусканием подаваемого катодного тока; в предпочтительном варианте выполнения конструкция (1) непрерывно омывается раствором (8) ингибитора; протекание первого подаваемого тока поддерживается, пока величина тока относительно неизменна на уровне, составляющем, по крайней мере, половину начального уровня первого подаваемого тока. Концентрация ионов определяется измерением величины тока при поддержании выбранного напряжения. Раствор (8) ингибитора может быть использован в сочетании с электроосмотическим током для переноса ионов в бетон к стали; это может быть сделано до включения катодного подаваемого тока или одновременно с ним посредством использования вторичных электродов (6, 7). Программируемые средства управления в источнике энергии осуществляют переключение из одного режима подачи в другой, когда потребление тока, определяемое плотностью тока, становится экономически невыгодным.Международная заявка была опубликована вместе с отчетом о международном поиске.
