Vim lub siab concentration ntawm calcium thiab magnesium ions nyob rau hauv cov tshuaj electrolytic, lub titanium electrodecathode yog nquag scaling tom qab ib lub sij hawm ntawm electrolysis. Txoj kev kho mob yog raws li nram no:
1. Yuav kom txo tau cov sedimentation thiab scaling, cov dej nyoos yog softened kom tshem tawm cov khib nyiab, tej yam colloidal, thiab organic impurities. Qhov no tuaj yeem tiv thaiv lossis txo cov sedimentation thiab scaling, thiab kev kho ua ntej kuj tseem tuaj yeem ua kom tshem tawm cov tawv tawv ntawm cov dej nyoos, tiv thaiv kev tsim cov scaling.
2. Pickling txoj kev: yeej ib txwm muaj me me ntawm precipitated scale generated thaum lub sij hawm ua hauj lwm ntawm electrodialysis, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas tsis zoo dej. Tom qab cov tsub zuj zuj mus rau ib qho twg, kev kho pickling yog xav tau. Raws li qhov xwm txheej, kev kho cov pickling tsis tu ncua yog ib txoj hauv kev yooj yim thiab siv tau los tshem tawm cov sedimentation yam tsis muaj kev cuam tshuam cov khoom siv. Lub voj voog nyob ntawm qhov xwm txheej tiag tiag, feem ntau yog ntxuav nrog 1 feem pua rau 2 feem pua ntawm hydrochloric acid ncig.
3. Siv rov qab electrode: Tsis tu ncua thim rov qab electrode hloov cov kev taw qhia ntawm ion tsiv teb tsaws. Raws li qhov xwm txheej tiag tiag, cov electrode feem ntau thim rov qab txhua 2-8 teev. Nyob rau hauv xyoo tas los no, tsis siv neeg electrode swapping tau nquag siv ob qho tib si hauv tsev thiab thoob ntiaj teb li ntawm 15-30 feeb. Ua li no, txawm tias nag lossis daus me ntsis tuaj yeem raug tshem tawm zoo. Txawm li cas los xij, feem ntau rov qab electrode swapping yuav tsum zoo ntawm tus ntsia thawv electrode thiab poob siab ntawm titanium electrode. Nws yog ib qho tsim nyog yuav tau xaiv cov khoom zoo Electrode nrog muaj zog corrosion kuj.
