1.Yuav ua li cas corrosion resistant yog ib tug tsis kho liab qab board?
Cov yam ntxwv ntawm lub cev: Txias- cov nplooj ntawv hlau yog ua los ntawm cov pa roj carbon steel, uas tuaj yeem ua rau cov pa oxygen thiab dej hauv huab cua ntawm chav tsev kub, ua rau xeb.
Cov txiaj ntsig zoo sib xws: Piv rau cov ntawv kub - dov cov ntawv ntawm tib lub ntsiab lus, cov ntawv txias- cov ntawv yob ua tau zoo dua corrosion kuj. This is because a key process in cold rolling-bright annealing-forms a very thin and dense oxide film on the steel surface, which effectively isolates the steel from air and moisture, providing basic protection. Tsis tas li ntawd, kev tswj xyuas qhov tseeb ntawm cov khoom siv hlau xws li chromium, npib tsib xee, thiab tooj liab hauv cov hlau tuaj yeem txhim kho nws qhov kev tiv thaiv corrosion rau qee yam.
2.Dab tsi yog lub luag haujlwm ntawm zinc txheej?
Kev cais lub cev: cais cov hlau los ntawm qhov chaw corrosive.
Electrochemical kev tiv thaiv (sacrificial anode): Txawm hais tias cov txheej txheem puas thiab cov hlau raug, zinc, yog cov tshuaj lom neeg ntau dua li cov hlau, yuav nyiam "siv" nws tus kheej los tiv thaiv cov hlau substrate. Yog li ntawd, lub neej ntawm galvanized txias - dov steel ntawv tuaj yeem yog 15-30 npaug ntawm cov ntawv hlau zoo tib yam. Nrog cov txheej txheem tiav tiav, qhov kev tiv thaiv corrosion ntawm cov ntawv galvanized tuaj yeem txhim kho ntxiv.
3.Yuav ua li cas corrosion resistant yog tshwj xeeb weathering hlau?
Kuj tseem muaj hom tshwj xeeb ntawm cov khoom txias txias, xws li ArcelorMittal's Indaten® series, uas, los ntawm kev ntxiv cov ntsiab lus alloying xws li tooj liab, chromium, thiab phosphorus, tso cai rau nws los tsim cov txheej oxide tuab (feem ntau hu ua "rust layer" lossis "passivation layer") uas ruaj khov rau hauv ib puag ncig ntuj. Cov txheej xeb no zoo tiv thaiv cov hlau sab hauv los ntawm kev txuas ntxiv mus rau corrode, yog li tso cai rau siv "liab qab" yam tsis tas yuav txheej txheej.
4.Dab tsi yog vim li cas rau qhov tsis zoo corrosion kuj ntawm liab qab txias-rolled steel los xij?
Nws rusts yooj yim heev thiab yuav tsum tau ua tam sim ntawd los yog tiv thaiv xeb.
5.Dab tsi yog vim li cas rau qhov zoo tshaj corrosion kuj ntawm huab cua tshwj xeeb- tiv taus txias- dov steel ntawv?
Ib txheej tuab, tiv thaiv xeb yog tsim los ntawm cov hlau alloy, tshem tawm qhov xav tau rau kev pleev xim.
