Hauv kev ua haujlwm ntawm engineering, cov laj thawj dab tsi rau kev tiv thaiv Cathodic? Koj paub ntau npaum li cas txog nws? Hauv qhov no, cia peb kawm txog nws ua ke, cia siab tias yuav pab koj.
1. Corrosion muaj peev xwm lossis muaj peev xwm
Corrosion muaj peev xwm (ntuj muaj peev xwm): txhua tus hlau raus hauv ib qho nruab nrab muaj qee lub peev xwm, uas yog hu ua kev muaj peev xwm corrosion (ntuj muaj peev xwm) ntawm cov hlau.
Corrosion muaj peev xwm tuaj yeem qhia cov txheeb ze yooj yim ntawm cov hluav taws xob tsis ua hluav taws xob. Qhov ntau tsis zoo rau corrosion muaj peev xwm, qhov yooj yim nws yog kom poob tshuab hluav taws xob.
Peb hu rau: ntu qhov twg electrons yog ploj ntawm lub cheeb tsam anode.
Ntu uas cov hluav taws xob uas tau txais yog canhode cheeb tsam.
Lub anode thaj chaw yog corroded vim tias poob ntawm cov tshuab hluav taws xob (piv txwv li, Iron attrator thiab ua cov hlau istolve rau hauv av), thiab thaj chaw cathode muaj kev tiv thaiv los ntawm cov tshuab hluav taws xob.
2. Kev Siv Hluav Taws Xob
Txhawm rau muab piv cov peev xwm electrode ntawm ntau yam hlau, muaj ib qho kev siv hluav taws xob.
Lub sulpate tooj liab sulfate siv electrode muaj cov peev xwm zoo thiab ruaj khov ntawm electrode lub peev xwm, cov qauv yooj yim, thiab yog siv dav hauv kev tiv thaiv Cathodic.
3. Cathodic kev tiv thaiv
Lub hauv paus ntsiab lus ntawm kev tiv thaiv Cathodic: nws yog ntxiv cov hluav taws xob hluav taws xob loj, yog li ntawd txhua tus neeg siv hluav taws xob tsis yooj yim, yog li ntawd txhua qhov chaw tsis yooj yim, yog li ntawd txhua tus neeg siv hluav taws xob tsis yooj yim sua kom yooj yim rau cov hluav taws xob thiab ua kom muaj cov tshuab hluav taws xob thiab dhau los ua cov tshuaj hluav taws xob
Muaj ob txoj hauv kev ua tiav lub hom phiaj no:
1) kev tiv thaiv kev tiv thaiv Cathodic: Nws yog txuas cov hlau nrog cov tshuab hluav taws xob tsis zoo rau cov hlau muaj kev tiv thaiv, kom tag nrho cov hlau tiv thaiv yog qhov tsis zoo thiab tib lub peev xwm.
Nta: Hom no yooj yim thiab yooj yim, tsis xav tau ib qho khoom siv hluav taws xob sab nraud, thiab tsis tshua muaj kev cuam tshuam rau hauv cov xeb.
Daim ntawv thov: Tiv thaiv cov qauv hlau me lossis cov av tsis tshua muaj cov chaw muaj tsawg dua 100 ohms. Meters). Xws li: Urban cov yeeb nkab tes hauj lwm, tso tsheb hlau luam me me, thiab lwm yam.
2) Txaus siab rau kev tiv thaiv tam sim no: los ntawm kev tiv thaiv DC sab nraud, yog li qhov muaj peev xwm tiv thaiv hlau yog qis dua li ntawm ib puag ncig hlau.
Daim Ntawv Thov: Tiv thaiv cov txheej txheem hlau loj lossis cov hauv av nrog cov kav dej siab tiv thaiv, pawg nyob ntev, thiab lwm yam.
