Cov yeeb nkab corrosion yog ib qho teeb meem tshwm sim. Yog li ntawd, txhawm rau zam lossis txo qhov corrosion ntawm cov raj xa dej, nws yog ib qho tsim nyog yuav tsum tau ua cov tshuaj tiv thaiv corrosion. Nyob rau hauv ib txwm muaj xwm txheej, txoj kev tiv thaiv corrosion ntawm cov yeeb nkab steel yog siv cov tshuaj tua kab mob, los yog qhov chaw ntawm lub raj hlau tshem tawm yog sib npaug rau saum npoo ntawm cov kav hlau hlau thiab ua tib zoo thov nws ntom ntom ntawm cov xim pleev xim, lossis cov xim sib npaug. nyob rau sab hauv phab ntsa ntawm cov yeeb nkab steel; Txawm hais tias qee cov kav hlau tau muaj kev tiv thaiv corrosion, qhov no tsis tau txhais hais tias lawv tuaj yeem siv tau ntau xyoo. Yog li, dab tsi yog qhov cuam tshuam rau lub neej kev pab cuam ntawm cov kav dej anticorrosive steel? Yam twg yog qhov tseem ceeb? Peb yuav daws tau li cas?
Txhawm rau txuas ntxiv kev pab cuam lub neej ntawm cov kav dej los tiv thaiv corrosion, lub neej kev pab cuam ntawm cov kav dej steel yog nyob ntawm qhov loj ntawm txoj kev tiv thaiv corrosion ntawm cov kav hlau. Yog li ntawd, cov ntaub ntawv zoo anticorrosive thiab anticorrosive txoj kev yuav tsum tau siv. Tshwj xeeb, nws tau muab faib ua ob lub ntsiab lus:
(1) Txhawm rau txuas ntxiv lub neej kev pab cuam ntawm cov kav dej los tiv thaiv corrosion, koj yuav tsum pib nrog kev xaiv cov khoom siv tshuaj tiv thaiv.
Cov ntaub ntawv siv los tiv thaiv cov coatings feem ntau yog coal scorched oil enamel xim, uas tuaj yeem tiv thaiv cov kav dej zoo dua. Txawm li cas los xij, cov ntaub ntawv no kuj muaj ntau yam tsis txaus, uas txwv lawv qhov kev thov; Qhov tshwm sim ntawm kev tiv thaiv-corrosion-soluble hmoov txheej coj txoj kev loj hlob sai ntawm cov kav dej tiv thaiv tshuab.
Lub ntsiab kom zoo dua ntawm epoxy resin anticorrosive melting hmoov txheej yog zoo corrosion kuj, zoo mechanical zog thiab muaj zog anti-cathode stripping. Cov txheej txheem no yog ib txheej ntawm overloaded epoxy hmoov txheej, ob txheej-txheej hnyav-loaded epoxy hmoov txheej Ua ke nrog cov txheej txheem tiv thaiv corrosion ntawm peb-txheej hnyav-loaded epoxy hmoov txheej tuaj yeem tiv thaiv cov yeeb nkab steel rau qhov loj tshaj plaws, txo qis. corrosion ntawm steel yeeb nkab pawg, thiab zoo tau txais cov yeeb nkab anticorrosive thiab yas hauv ob sab phlu yeeb nkab; Muaj tseeb thiab kev tshawb fawb, haum rau kev tiv thaiv corrosion ntawm cov kav dej hauv av lossis cov kav dej hauv qab.
(2) Kev kho kom zoo los tiv thaiv corrosion kom ntev kev pab cuam lub neej ntawm cov kav dej tiv thaiv corrosion.
Thaum kho anticorrosive steel kav, xyuam xim rau cov ntsiab lus hauv qab no: deg pre-processing, tshuaj tsuag txheej ntawm cov hlau nto ntawm phab ntsa sab hauv ntawm lub siab steel yeeb nkab kom tshem tawm xeb, thiab tsim cov xeb tshem tawm los yog txhua yam, txhua yam xeb tshem tawm los ntawm xuab zeb txau thiab lwm txoj hauv kev tuaj yeem txhim kho kev ua haujlwm thiab txo cov pa phem rau tib neeg thiab huab cua; Thaum cov phab ntsa sab hauv thiab sab nrauv ntawm lub raj xa dej yuav tsum tau los yog cov phab ntsa sab hauv ntawm cov kav dej yuav tsum tau Cov xeb tshem tawm zoo tshem tawm cov raj xa dej, sab hauv thiab cov oxides ntawm sab nrauv.
Tom qab lub puab phab ntsa ntawm cov xim hlau yeeb nkab, tom qab qhov zoo ntawm lub puab phab ntsa ntawm cov yeeb nkab steel yog tsim nyog, cov xim yuav tsum tau pleev xim rau lub sij hawm; cov xim sab saud yuav tsum tau ua nruj me ntsis raws li cov lus qhia ntawm cov chaw tsim tshuaj pleev xim; Ua tiav hauv 8 teev.
