Description
В процессе хромировани железных и стальных изделий электролит постененно обогащаетс железом, а сопротивление ванны возрастает так сильно, что напр жение на ней увеличиваетс в 1,5 раза и более. Поэтому вопрос О регенерации электролита весьма актуален.During the chromium-plating of iron and steel products, the electrolyte is enriched with iron, and the resistance of the bath increases so much that the voltage on it increases by a factor of 1.5 and more. Therefore, the question of electrolyte regeneration is very relevant.
Согласно изобретению, дл регенерации хромового электролита е ванну с очищаемым от железа электролитом помещают пористый сосуд, содержащий раствор вещества, осаждающего железо; через ванну пропускают посто нный электрический ток таким образом, чтобы раствор в пористом сосуде вл лс католитом.According to the invention, for the regeneration of the chromic electrolyte e, a bath with an electrolyte to be cleaned from iron is placed a porous vessel containing a solution of the substance precipitating iron; a constant electric current is passed through the bath in such a way that the solution in the porous vessel is catholyte.
В качестве такой лсидкости может быть применен, например, раствор соли хромовой кислоты Na2Cr2O7, Na2CrO4 или соль такой кислоты, котора дает анион, не оказывающий вредного вли ни на состав хромовой ванны, например, Ма2СОз.As such a liquidity, for example, a solution of a chromic acid salt Na2Cr2O7, Na2CrO4 or a salt of such an acid that gives an anion that does not adversely affect the composition of the chromium bath, for example, Ma2CO3, can be used.
Под действием тока ионы железа проникают через диафрагму в католит и, наоборот, анион хромовой кислоты или другой кислоты через диафрагму переходит в анолит, которым в данном случае служит хромовый электролит. Железо внутри диафрагмы в виде гидрата или другого нерастворимого соединени садитс на дно диафрагмы.Under the action of current, iron ions penetrate through the diaphragm into the catholyte and, conversely, the anion of chromic acid or another acid passes through the diaphragm into the anolyte, which in this case is the chromic electrolyte. Iron inside the diaphragm, in the form of a hydrate or other insoluble compound, sits at the bottom of the diaphragm.
Предмет изобретени Subject invention
Способ очистки хромового электролита от железа, отличающийс тем, что в ванну с очищаемым электролитом помещают пористый сосуд, содержащий раствор вещества , осаждающего железо, и через ванну пропускают посто нный электрический ток таким образом, чтобы раствор в пористом сосуде вл лс католитом.A method for purifying chromic electrolyte from iron, characterized in that a porous vessel containing a solution of an iron precipitating substance is placed in a bath of electrolyte being cleaned and a constant electric current is passed through the bath so that the solution in the porous vessel is catholyte.
