Abstract
The present invention features that the crimping surfaces of the bus bar and anode guide rod are cleaned with the cleaning liquid comprising dodecyl benzene sulfonic acid 1-20 wt%, alkali metal hydroxide 0.5-12 wt%, triethanolamine, 1-25 wt%, JFC 0.1-10 wt%, calgon 0.5-10 wt%, ethanol 5-10 wt%, non-ionic surfactant 1-18 wt% and butylcellusolve 5-10 wt% and water (the balance). Washing the anode guide rod with the cleaning liquid can reduce the electrode voltage obviously, lower the power consumption of electrolyzing aluminium greatly.
Description
Technical field
The invention belongs to the technical field of electrolytic aluminium anode guide rod surface scale removal.
Background technology
Producing with electrolytic process in the process of electrolytic aluminum, the anode rod surface is easy to generate schmutzband, this layer dirt composition complexity, there is the conductivity that has influenced electrode greatly in it, particularly on the crimping face between bus and the anode rod,, directly have influence on conductivity efficient if schmutzband has been arranged, make electricity lead the process power consumption and strengthen, the production cost of aluminium improves.What but, do not handle so many factories just have antianode guide rod surface to carry out scale removal, thereby the current consumption of producing aluminium can fall, and directly has influence on the productivity effect of factory owing to do not have good method to remove this layer dirt at present with lower cost.
Summary of the invention
The technical problem to be solved in the present invention is that the anode rod crimping face to electrolytic aluminum carries out surperficial scale removal and handles.
The present invention solves the problems of the technologies described above with following technical scheme: use the clean-out system cleaning bus of following prescription and the crimping part surface (weight %) of anode rod
Witco 1298 Soft Acid 1-20 alkali metal hydroxide 0.5-12
Trolamine 1-25 JFC 0.1-10
Sodium hexametaphosphate 99 0.5-10 ethanol 5-10
Nonionic surface active agent 1-18 ethylene glycol monobutyl ether 5-20
Water surplus
Use clean-out system of the present invention, as long as the crimping part surface of antianode guide rod and bus cleans, make these surfaces expose the aluminium crystal, can make the interface conductivity of crimping face better, electrode voltage never cleans the mean value 7.5mv after crimping mean value 15.8mv in front reduces to cleaning during electrolytic aluminum, and antihypertensive effect is fairly obvious, current consumption also reduces significantly, and processing cost is cheap, and easy handling, popularizing application prospect are very good.
Embodiment
Clean-out system is prepared below adopting: (weight %)
