1. Ua ntej: Yuav Ua Li Cas Galvanized Steel Ua Haujlwm (Kev Tshawb Fawb Tom Qab Txheej)

Txhawm rau kom nkag siab tias yuav ua li cas thaum galvanized steel tau ntub, peb yuav tsum xub qhib lub galvanization tiv thaiv steel li cas. Galvanized steel yog carbon steel coated nrog ib txheej ntawm zinc (ntawm kub-dip galvanization los yog electro-galvanization). Zinc ua haujlwm rau ob lub luag haujlwm tseem ceeb:

1.1 Kev Tiv Thaiv Kev Tiv Thaiv

Cov zinc txheej ua raws li lub cev tiv thaiv, thaiv cov dej noo, oxygen, thiab cov khoom corrosive los ntawm kev ncav cuag cov hlau hauv qab. Ib txheej tuab, siab - zoo zinc txheej (zoo li qhov kub ntawm -dipped galvanized steel, HDG) tsim ib qho kev thaiv tsis tau- thaum tsis zoo, nws tiv thaiv xeb los ntawm cov hlau.

1.2 Kev Tiv Thaiv Kev Txhaum Cai Anode

Zinc yog ntau "electrochemically active" dua li hlau. Qhov no txhais tau tias yog zinc txheej yog khawb los yog puas (tshwj xeeb cov hlau), zinc yuav corrodeua ntej- txi nws tus kheej los tiv thaiv cov hlau. Qhov "cathodic tiv thaiv" no ua haujlwm txawm tias cov txheej txheem raug cuam tshuam, tsuav yog muaj cov zinc txaus txaus los teb.

Thaum galvanized steel tau ntub, ob lub tshuab no ncaws rau hauv iav. Cov tshuaj tiv thaiv ntawm zinc, dej, thiab oxygen tsis yog ib qho kev ua tsis tiav -nws yog txheej txheej ua nws txoj haujlwm.

2. Yuav ua li cas thaum Galvanized hlau ntub dej? Cov tshuaj tiv thaiv

Thaum cov hlau galvanized raug dej (thiab oxygen), cov tshuaj tiv thaiv kab mob tshwm sim los tsim cov txheej txheem tiv thaiv zinc corrosion. Ntawm no yog ib kauj ruam -los ntawm - kauj ruam tawg:

2.1 Cov Lus Teb Pib: Zinc Oxide Tsim

Thawj cov tshuaj tiv thaiv tshwm sim thaum zinc (Zn) reacts nrog oxygen (O₂) thiab dej (H₂O) los tsimzinc oxide (ZnO):

2Zn + O₂ → 2ZnO

Zinc oxide yog ib txheej nyias, hmoov txheej -tab sis nws sai sai reacts nrog dej ntau los tsim ib qho chaw ruaj khov dua.

2.2 Thib Ob Reaction: Zinc Hydroxide

Zinc oxide reacts nrog dej los tsimzinc hydroxide (Zn (OH) ₂):

ZnO + H₂O → Zn(OH)₂

Zinc hydroxide yog me ntsis soluble hauv dej, tab sis nws tsis yooj yim ntxuav. Hloov chaw, nws ua ke nrog cov pa roj carbon dioxide (CO₂) los ntawm huab cua los tsim cov yeeb yaj kiab ruaj khov thiab tiv thaiv.

2.3 Qhov Kawg Reaction: Zinc Carbonate ("Passive Layer")

Zinc hydroxide reacts nrog CO₂ tsimZinc carbonate (ZnCO₃), tseem hu ua "hydrozincite." Nov yog txheej txheej tiv thaiv tseem ceeb:

Zn(OH)₂ + CO₂ → ZnCO₃ + H₂O

Zinc carbonate yog tawv, insoluble, thiab adheres nruj nreem rau zinc txheej. Nws ua raws li qhov thib ob barrier, slowing down ntxiv corrosion ntawm zinc. Cov txheej txheem passive no yog vim li cas cov hlau galvanized tuaj yeem tiv taus ntau xyoo ntawm kev raug dej -txawm tias los nag, dej lwg, lossis cov av me me- yam tsis muaj xeb.

Kab hauv qab:

Thaum cov hlau galvanized ntub dej, nws tsis xeb - nws tsim cov txheej txheem zinc carbonate uas txuas nws lub neej ntev. Cov txheej txheem yog ntuj, thiab cov txheej txheem yog tus kheej - kho (mus rau qib) tsuav yog muaj zinc txaus los teb.

3. Thaum ntub dej dhau los ua teeb meem: Cov yam ntxwv uas ua kom ceev Galvanized Steel Corrosion

Thaum galvanized steel yog tsim los tswj cov dej noo, tsis yog txhua qhov dej yog tib yam. Qee qhov xwm txheej tuaj yeem ua kom zinc corrosion, hla cov txheej txheem passive, thiab thaum kawg tua cov hlau hauv qab. Nov yog cov tseem ceeb ntawm kev pheej hmoo:

3.1 Hom dej

• Cov dej tsis huv (dej nag, kais dej): Tsawg ntsev thiab tshuaj lom neeg - ua rau muaj kev pheej hmoo tsawg. Galvanized steel tuaj yeem kav ntev li 20-50 xyoo hauv qhov chaw dej tsis qab (piv txwv li, laj kab sab nraum zoov hauv tsis yog- thaj chaw ntug dej hiav txwv).
• Dej ntsev (dej hiav txwv, ntug dej hiav txwv): Cov ntsiab lus ntsev siab (chlorides) yog tshuaj lom rau zinc. Chlorides rhuav tshem cov zinc carbonate txheej, tiv thaiv nws los ntawm kev hloov kho. Qhov no accelerates zinc corrosion, txiav lifespan mus rau 5-15 xyoo (txawm rau HDG steel).
• Industrial / acidic dej (cov nroj tsuag tshuaj, dej khib nyiab): Cov kua qaub, alkalis, lossis cov hlau hnyav (xws li sulfuric acid, ammonia) yaj cov zinc txheej sai. Lub neej yuav poob mus rau 1-5 xyoo yog tias tsis muaj kev tiv thaiv.
• Hard dej (muaj cov ntxhia hauv siab): Minerals tuaj yeem tso rau ntawm zinc txheej, ntxiab ya raws thiab tsim cov chaw xeb hauv zos.

3.2 Txheej zoo & Thickness

• Kub-Dipped Galvanized (HDG): Thick zinc txheej (85-150 microns) tiv taus dej puas zoo dua li nyias electro-galvanized (EG) txheej (5-25 microns). EG steel tej zaum yuav poob rau hauv qhov chaw ntub dej hauv 3-10 xyoo xwb.
• Cov txheej txheem tsis zoo: Cov khoob khoob, npuas, lossis cov pob me me hauv txheej zinc (feem ntau hauv qis- zoo galvanization) yog cov ntsiab lus tsis muaj zog uas dej tuaj yeem nkag mus, ua rau xeb.

3.3 Txheej Kev puas tsuaj

Kos, dents, los yog txiav rau cov zinc txheej (los ntawm kev teeb tsa, cov cuab yeej, lossis kev cuam tshuam) nthuav tawm cov hlau. Thaum kev tiv thaiv kev txi tseem ua haujlwm, zinc nyob ib puag ncig kev puas tsuaj yuav corrode sai dua. Yog tias qhov kev puas tsuaj loj heev (xws li khawb loj), cov hlau yuav xeb ua ntej zinc tuaj yeem tiv thaiv nws.

3.4 Galvanic Corrosion (Kev sib cuag nrog cov hlau tsis sib xws)

Thaum galvanized steel nyob rau hauv ntub dej nrog ntau "noble" hlau (xws li, tooj liab, tooj dag, stainless hlau 316), galvanic cell forms. Zinc ua raws li cov anode thiab corrodes sai heev los tiv thaiv lwm yam hlau. Piv txwv li:

• Ib tug galvanized steel bracket bolted rau ib tug tooj liab yeeb nkab nyob rau hauv ib tug ntub dej da dej yuav corrode sai npaum li cas nws yog ua ke nrog hlau los yog txhuas.

3.5 Tsis muaj qhov cua

Cov khoom ntub dej (piv txwv li, nruab nrab ntawm cov hlau galvanized thiab ntoo hauv ib lub lawj uas tsis muaj cua sov) tsim ib qho chaw ntub dej uas ua kom muaj corrosion. Dej tsis tuaj yeem evaporate, yog li cov zinc txheej yog tas li raug rau ya raws.
