Description
Technical field
The invention belongs to field of hydrometallurgy, be specifically related to the process technique of positive plate conductive copper bar.
Background technology
In the production process of electrolytic manganese metal, positive plate is main consumable part, and it is mainly mixed by a certain percentage by silver, stannum, lead etc., through melting, mix, cast, cold pressing, shearing, stamping makes.
Being welded with the conductive copper bar of conduction on alloy lead anode mainboard, in the manufacture process of positive plate, its copper bar is Reusability after reclaiming mostly.Copper bar can be adsorbed with impurity through recycling rear surface and produce oxide, if do not removed, after directly pouring into a mould with metal, will there is bigger contact resistance thus increasing electric energy consume between copper-lead.Current most of positive plate producer is all that copper bar does not process direct use when recycling the old copper bar of positive plate.The positive plate that so directly cast uses after testing, copper bar, with the contact resistance that there is 0.01 Ω 0.1 Ω between metal, makes positive plate generate heat in electrolytic process and seriously produces electric energy loss, causes that Faradaic current efficiency is low.
Summary of the invention

(2) hydrochloric acid cleans, and with the hydrochloric acid solution of 30%, copper bar is carried out；
(3) it is coated with protective cream, by the protective cream even application for preventing secondary oxidation in copper bar surface；
(4) dry, at 200 DEG C of temperature, copper bar is dried, be only divided into evaporation solid carbon dioxide；
(5) copper bar lead plating, cast metal.
Described protective cream includes the raw material of following mass fraction and makes: zinc chloride 25 ~ 35%, ammonium chloride 15 ~ 25%, and all the other are water.
