Description

Известен способ очистки латуииых аппаратов путем обработки раствором сол ной кислоты.There is a known method of cleaning latium apparatuses by treating with hydrochloric acid solution.
Однако известный способ не примен етс дл очистки латунных аппаратов от медесодержащих отложений, так как накапливающиес в растворе ионы меди способствуют интенсификации коррозионных процессов на поверхности латуни.However, the known method is not applied to the cleaning of brass apparatus from copper-bearing deposits, since copper ions accumulating in the solution contribute to the intensification of corrosion processes on the surface of brass.
Предложенный способ отличаетс от известного тем, что в раствор сол ной кислоты добавл ют железную стружку. Это обеспечивает возможность очистки от медесодержащих отложений и способствует предотвращению растворени латуни.The proposed method differs from that in that iron chips are added to the hydrochloric acid solution. This allows for the removal of copper-containing deposits and helps prevent the dissolution of brass.
Способ реализуетс следующим образом.The method is implemented as follows.
Очистку поверхности от медесодержащих отложений производ т путем обработки раствором сол ной кислоты, в который помещают стальную или железную стружку.The surface is cleaned of copper-containing deposits by treatment with hydrochloric acid solution, in which steel or iron chips are placed.
Струл :ка способствует восстановлению ионов меди, образующихс при растворении отложений , до металлического состо ни , в результате чего скорость коррозии латуни снижаетс до допустимого значени .Strum: It contributes to the reduction of copper ions formed during the dissolution of deposits to a metallic state, as a result of which the corrosion rate of brass is reduced to an acceptable value.
Установлено, что скорость коррозии латуни Л-68 в 1-2%-ном растворе, сол ной кислоты, содержащем 1-2 г/л ионов меди, составл ет 25-40 Г/М2-Ч. Введение в этот раствор стальной стружки способствует снижению скорости коррозпп до 1 г/м ч.It has been established that the corrosion rate of brass L-68 in a 1-2% solution of hydrochloric acid containing 1-2 g / l of copper ions is 25-40 G / M2-H. The introduction of steel chips into this solution helps to reduce the corrosion rate to 1 g / m.
