Dab tsi yog qhov anticorrosion yam ntxwv ntawm galvanized ntawv?

Cov tswv yim tseem ceeb ntawm kub dip galvanizing ntawm galvanized ntawv Nyob ntawm seb qhov corrosion kuj ntawm kub dov strip steel yog zoo heev tom qab txheej txheej ntawm kub dip galvanizing yog them, uas yuav txuag tau raw cov ntaub ntawv thiab cov kev pab cuam thiab muab tag nrho cov kev ua si rau cov zoo heev economic kev pab cuam thiab tej yam ntuj tso kev pab cuam.  

Tus yuam sij rau kev saib xyuas kev ua tau zoo ntawm kub dip galvanizing txheej ntawm galvanized ntawv rau kub dov strip steel yog raws li nram no:  

(1) Thaum cov hlau phaj tuab tsis zoo, tsuas yog zinc corrosion, vim tias cov khoom siv zinc corrosion muaj cov txiaj ntsig zoo, yog li tus nqi corrosion qeeb heev, lub neej kev pab yuav yog 15-30 npaug ntawm galvanized steel phaj.  

(2) qhov xwm txheej feem ntau yog cov ntawv galvanized hauv kev tsim khoom thiab kev ua haujlwm, kev teeb tsa, daim ntawv thov, qhov chaw khawb, lossis lwm yam laj thawj txheej hauv qab qhov puas, kub dov strip steel raug tawm ntawm lub qhov txhab nyob rau hauv ib puag ncig ntuj, yog tias yog cov tshuaj ntawm cov ntaub ntawv tsis yog xim hlau, cov blocks raug etched tam sim ntawd, tab sis cov yam ntxwv ntawm cov ntawv txias txias steel ntawv tshwj xeeb, ua rau etching tus nqi qeeb, nyob rau hauv txoj kev no Cov zinc nyob rau hauv lub txheej thiab cov hlau nyob rau hauv kub dov sawb steel ua ib tug galvanic. cell nyob rau hauv ntub thiab txias ib puag ncig, vim hais tias tus qauv electrode peev xwm ntawm zinc tsuas yog -1.05V, tsawg dua -0.036V ntawm hlau, yog li zinc raws li ib tug anodic oxidation los ntawm huab cua oxidation, thiab hlau raws li ib tug tsis zoo phaj kom tau txais kev kho. Vim tias cov khoom tom qab Zinc yog lub sijhawm ntau heev, lub sijhawm tshuaj tiv thaiv tsis tshua qeeb, hauv lwm lo lus, tag nrho cov corrosion corrosion tau zoo heev. Hom kev tiv thaiv no yog hu ua corrosion resistance.
