The technique for improving sacrificial magnesium alloy anode current efficiency.
Background technology
Currently, the current efficiency of sacrificial magnesium alloy anode is to weigh the important indicator of product quality, when current efficiency refers to electrolysis
On the electrode actual deposition or the amount of the substance of dissolving with by the ratio between theoretical calculated precipitation or meltage.Influence magnesium anode electricity
Flow efficiency factor, essentially consist in the characteristic of anode product itself, except sacrificial anode product have high low potential exceptionally, besides
The degree of purity of anode product, degree of purity is higher, and the value of current efficiency is also higher.Moulding process also determines the electric current of product simultaneously
Efficiency after formed product of casting, needs to carry out Water Quenching to make the crystal grain refinement of anode product, improves the current efficiency of product.
Current efficiency is to judge the important indicator of sacrificial anode qualification, the current efficiency of high potential MgMn series sacrificial anodes >=
50% is qualified products, and in industrial actual production, the qualification rate of product only has 70% or so；Current efficiency has 45-50%'s
20%, current efficiency has 10% 40-45%'s.It is less than 50% product for current efficiency, the degree of purity of product is can not to change
, it is desirable to it improves current efficiency and just needs to carry out it solution treatment and carry out water-cooled process, promote its current efficiency.
In conjunction with magnesium manganese binary phase diagraml, in MgMn alloys Mn contents in 0.5%-1.3%, crystallization temperature at 550 DEG C -700 DEG C,
In this temperature range, the β phases in MgMn alloys can be dissolved into melt, have the function that solution strengthening, while can refine
Crystal grain reduces the self-corrosion of sacrificial anode, improves current efficiency.Therefore, sacrificial magnesium alloy is improved using a kind of new technique
The current efficiency of anode has seemed very necessary.
