Description
Technical field
The present invention relates to a kind of Zinc electrolysis additive and its application methods, belong to the technical field of zinc wet method electrodeposition.
Background technology
At present, it is fine and close in order to make cathode zinc metal sheet surfacing in the conventional process techniques for depositing the electric zinc of production in zinc electrolysis
It is smooth, ingotism is not generated, having lot of documents report needs to add in a large amount of additive gelatine in Zinc sulfate electrolyte.But this
Kind additive gelatine is being electrolysed under acid condition, is decomposed and is generated the organic matters such as amino acid, tank voltage is caused to increase, power consumption liter
Height increases production cost；And when fluorine content is in 100 ~ 200mg/L in electrolyte, zinc metal sheet difficulty stripping, increase labor intensity and
Production cost influences normally to produce.Huang Juan etc. is at non-ferrous metal (Smelting Part)《Gelatine is to Long period zinc electro-deposit energy consumption and the moon
The influence of pole quality》In report ton zinc gelatine addition more than 0.3kg when, the unit dc consumption for making Zinc electrolysis is significantly risen
High, current efficiency is substantially reduced, and largely prominent knurl, color are obscure for produced cathode zinc rough surface, growth.
Invention content
The purpose of the present invention is be directed to above-mentioned existing industrial technology there are the problem of, propose a kind of Zinc electrolysis additive and its
Application method adds a small amount of sesbania gum in zinc electrodeposit liquid, can solve the technologies such as tank voltage raising and the stripping of zinc metal sheet difficulty and ask
Topic.
The present invention provides a kind of Zinc electrolysis additive, is 0.1 ~ 10 in mass ratio by sesbania gum and gelatine:1 ratio weighs mixed
Conjunction obtains mixture, is 1 ~ 4 by water and mixture quality ratio:1 ratio, adds water in mixture, leads to low-pressure steam heating
0.1 ~ 1h is dissolved, obtains Zinc electrolysis additive.
The present invention also provides the application methods of above-mentioned Zinc electrolysis additive, are as follows：
（1）Zinc electrolysis additive continuous uniform is added in zinc electrolyte；
（2）Tank voltage is 2.8 ~ 3.6V in electrolytic process, goes out slot after being electrolysed 24 ~ 48h, obtains qualified zinc metal sheet and waste electrolyte, electricity
The zinc metal sheet of solution output is easily peeled off.
Step（1）Total addition of the Zinc electrolysis additive is added in by 0.1 ~ 1kg/ tons of electric zinc.
The features of the present invention：This method in zinc electrolyte by adding in additive sesbania gum, instead of most of gelatine,
It is being electrolysed under acid condition, gelatine decomposes the organic matters such as generation amino acid and significantly reduces, therefore reduce tank voltage and electric energy
Production cost is saved in consumption；When fluorine content is in 100 ~ 200mg/L in electrolyte, after adding in additive sesbania gum, zinc metal sheet becomes
It is easily peeled off, hence it is evident that reduce labor intensity and production cost.
