Background technology
Contain caustic soda (being generated in electroplating process) inside electroplate liquid, generation oxidation is contacted instead with air on electroplate liquid surface
Sodium carbonate should be will produce.With the lasting progress of plating, the carbonate content inside electroplating liquid medicine can be continuously improved, and work as sodium carbonate
Concentration be more than admissible range, electroplating velocity can be caused slack-off, influence electroplating effect.
Alkaline zinc plating liquid will produce the accumulation of sodium carbonate after producing and using 1 year, general to require to be no more than 60g/L, when containing
Electroplating liquid medicine internal resistance increases when amount is more than 80g/L, temperature rises quickening, plating upper density limit reduces, and the electric conductivity of electroplate liquid is deteriorated.Work
Skill requires current density range to be actually only raised to 1.3A/dm2 or so for 1~4A/dm2, when current density is slightly higher, just has
Corner is burnt while electroplating liquid medicine heating is too fast, and dispersibility and covering power are deteriorated, and electroplating liquid medicine is pale brown without limpid, coating
The phenomenon that brittleness becomes larger.Electroplating efficiency reduces, electroplating time increases, and waste of resource increases cost.
Traditional processing includes following several method：
1) winter nights freeze method of cleaning：Bath solution is extracted into storage outdoors slot, carries out one night of naturally frozen by winter
Evening, the next morning cleaning storage trench bottom sodium carbonate.The method needs continuous freezing at least 3 times, but cannot fully erased carbon
Sour sodium.Disadvantage：It is cooled down using environment temperature, season limitation is big, and southern temperature height is not met by requirement, needs to prepare one
Electroplate liquid is pumped through with trough big as plating sump volume and is transferred back again to handle, volume accounts for greatly hall space, processing speed
Slowly, it and needs to stop production, low production efficiency, utilization rate of equipment and installations declines, and the production cost increases.
2) artificial ice cube freezes method of cleaning：Suitable stainless steel metal bucket is taken, ice cube is filled, is put into solution, static one section
Time, solution can crystallize precipitation on ice bucket outer wall afterwards to the cold, and such continuous processing is multiple, you can carbonate content is reduced,
It but cannot fully erased sodium carbonate.Disadvantage：Using the indirect cooling electroplate liquid in ice cube part, heat exchange efficiency is low, complicated for operation, processing
Speed is very slow.The method is also required to stop production, low production efficiency, and utilization rate of equipment and installations declines, and the production cost increases.
3) white lime or quick lime method of cleaning.Disadvantage：The filter plant for needing to invest a set of large size, to the operation water of worker
It is flat to require height, there is the risk for scrapping whole slot electroplate liquid, also needs to taking electroplate liquid into the carbonic acid for clearing up trench bottom again away after having handled
Calcium, quantities are huge.Equipment also needs to stop production, and cost increases.
4) solution cleaning part depreciation-retirement method：When cleaning and maintenance, a part of bottom solution is scrapped, a part of new soln weight is added
New slot allocation.Disadvantage：Electroplate liquid, equipment, which need to be scrapped, need to stop production processing, and cost is very high.
