Cov yeeb nkab hlau twg yuav tsis xeb?
Xeb yog cov bane ntawm cov kav hlau, uas ua rau cov txheej txheem tsis muaj zog thiab lub neej luv dua. Hauv ntau qhov kev lag luam thiab kev siv, nrhiav cov yeeb nkab hlau uas tiv taus xeb yog qhov tseem ceeb rau kev ua haujlwm ntev. Kab lus no yuav tshawb txog peb yam lus nug txog cov kav hlau uas tsis muaj xeb thiab muab cov lus teb los pab kos qhov xaus.
Nqe Lus Nug 1: Puas yog cov kav hlau stainless puas tiv taus xeb?
Teb:Yog lawm,stainless hlau kavyog heev resistant rau xeb. Stainless hlau muaj chromium, uas tsim cov txheej txheem tiv thaiv ntawm qhov chaw hu ua passive zaj duab xis. Cov yeeb yaj kiab no pab tiv thaiv cov hlau hauv qab los ntawm kev ua pa nrog oxygen, yog li inhibiting xeb tsim. Stainless hlau kav yog dav siv nyob rau hauv ntau yam lag luam uas corrosion kuj tseem ceeb heev, xws li cov kav dej, kev tsim kho, thiab tsheb.
Nqe Lus Nug 2: Puas yog galvanized steel yog qhov kev xaiv zoo los tiv thaiv xeb hauv cov kav dej?
Teb: Galvanized steel kavyog ib qho kev xaiv nrov rau kev tiv thaiv xeb. Cov kav dej no yog coated nrog ib txheej ntawm zinc, ua ib qho kev tiv thaiv tiv thaiv corrosion. Lub zinc txheej ua raws li kev txi anode, tiv thaiv cov hlau hauv qab txawm tias nws tau khawb lossis puas. Txawm li cas los xij, dhau sijhawm, zinc txheej tuaj yeem hnav, ua rau cov hlau tsis muaj zog rau xeb yog tias tsis tswj xyuas kom zoo.
Nqe Lus Nug 3: Cov kav dej txhuas puas tuaj yeem tiv thaiv xeb rau lub sijhawm ntev?
Teb:Tsis zoo li stainless hlau thiab galvanized steel kav, txhuas tsis yog xeb-resistant. Txawm li cas los xij, nws muaj tus yam ntxwv tshwj xeeb hu ua self-passivation. Thaum raug cov pa oxygen, txhuas ua ib txheej oxide nyias ntawm nws qhov chaw, uas tiv thaiv nws los ntawm corrosion ntxiv. Txawm hais tias cov kav dej txhuas yog lub teeb yuag thiab anodized rau kev txhim kho kev tiv thaiv, lawv feem ntau tsis zoo li corrosion-resistant li stainless hlau los yog galvanized hlau nyob rau hauv ib puag ncig hnyav.
Xaus:
Thaum tag nrho peb hom ntawm cov kav hlau sib tham - stainless hlau, galvanized steel, thiab txhuas - muab ntau qib ntawm xeb tsis kam, cov kav hlau stainless tau tawm los ua qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv xeb. Nrog lawv cov chromium-raws li passive zaj duab xis, stainless hlau kav zoo nyob rau hauv
withstanding cov teebmeem ntawm ya raws, oxygen, thiab corrosive hais. Lawv tau siv dav hauv ib puag ncig uas xeb tuaj yeem ua rau muaj kev txhawj xeeb loj, xws li cov kav dej, cov ntawv thov kev lag luam, thiab cov qauv hauv hiav txwv.
Galvanized steel kav, ntawm qhov tod tes, muab cov xeb zoo vim lawv cov zinc txheej. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum tsis tu ncua tshuaj xyuas thiab tswj cov zinc txheej kom ntseeg tau tias muaj kev tiv thaiv ntev tiv thaiv xeb. Yog tias cov txheej txheej hnav los yog puas lawm, cov hlau hauv qab yuav raug nthuav tawm thiab raug rau xeb tsim.
Txawm hais tias cov kav dej txhuas muaj cov khoom siv rau tus kheej, lawv tsis yog xeb-resistant li stainless hlau lossis galvanized hlau. Aluminium kav tej zaum tseem yuav raug corrosion thaum lub sij hawm, tshwj xeeb tshaj yog nyob rau hauv hnyav los yog acidic ib puag ncig. Anodization tuaj yeem txhim kho lawv cov kev tiv thaiv rau qee qhov, tab sis nws yog ib qho tseem ceeb uas yuav tau xav txog cov xwm txheej tshwj xeeb thiab muaj peev xwm cuam tshuam rau cov ntsiab lus corrosive ua ntej xaiv txhuas rau cov ntawv siv xeb-tiv taus.
Hauv kev xaus, thaum nrhiav cov yeeb nkab hlau uas yuav tsis xeb, cov kav hlau stainless yog qhov kev xaiv zoo tshaj plaws. Lawv qhov kev tiv thaiv corrosion thiab tiv thaiv cov yeeb yaj kiab ua rau lawv zoo tagnrho rau ntau yam kev lag luam thiab kev siv. Txawm li cas los xij, galvanized steel kav tuaj yeem yog lwm txoj hauv kev zoo yog tias khaws cia kom zoo los khaws cov zinc txheej. Thaum cov kav dej txhuas muaj cov khoom siv rau tus kheej, lawv yuav tsis muaj tib theem ntawm xeb tsis zoo li cov hlau tsis muaj steel lossis galvanized steel, ua rau lawv zoo dua rau qhov chaw tsis zoo.
