Ob leeg aluminium alloy keel thiab galvanized keel feem ntau yog siv los txhawb cov ntaub ntawv hauv qab nthab thiab muab faib phab ntsa, txhua tus muaj nws tus yam ntxwv tshwj xeeb thiab qhov zoo. Cov hauv qab no yog lawv qhov sib txawv ntawm cov khoom siv, kev ua haujlwm, kev siv ib puag ncig, thiab tus nqi:
1. Cov khoom sib txawv
Aluminium Alloy Keel: Aluminium alloy keel yog ua los ntawm txhuas alloy, uas yog lub teeb yuag, muaj zog siab, thiab zoo corrosion kuj. Aluminium alloy nws tus kheej muaj siab oxidation tsis kam, tswj kom zoo durability txawm nyob rau hauv ntub los yog ntsev tsuag ib puag ncig.
Galvanized Keel: Galvanized keel siv hlau ua cov khoom siv hauv paus, nrog rau qhov chaw galvanized los tiv thaiv xeb. Cov txheej txheej galvanized muab qee qhov kev tiv thaiv corrosion, tab sis piv rau aluminium alloy, galvanized keel muaj me ntsis qis corrosion kuj nyob rau hauv huab ib puag ncig.
2. Corrosion Resistance thiab Siv Ib puag ncig
Aluminium Alloy Keel: Vim nws muaj zog oxidation tsis kam, aluminium alloy tswj kev ua tau zoo txawm tias thaum raug huab cua los yog corrosive ib puag ncig rau ncua sij hawm. Tshwj xeeb tshaj yog tsim rau cov huab cua hauv hiav txwv lossis siab - thaj chaw av noo, xws li chav ua noj, chav dej, thiab hauv qab daus, muab kev tiv thaiv corrosion zoo dua.
Galvanized Keel: Galvanized keel kuj muaj qhov zoo corrosion kuj, tab sis qhov no yog feem ntau ntawm kev tiv thaiv ntawm zinc txheej. Thaum lub sij hawm, cov zinc txheej yuav maj mam corrode, tshwj xeeb tshaj yog nyob rau hauv cov av noo los yog acidic ib puag ncig, qhov twg galvanized keel yuav plam ib co ntawm nws anti-corrosion zog. Yog li ntawd, qhov chaw siv rau galvanized keel yog me ntsis txwv ntau dua li cov aluminium alloy keel.
3. Qhov hnyav thiab lub zog
Aluminium Alloy Keel: Aluminium alloy keel yog lub teeb yuag, haum rau tej yaam num uas yuav tsum tau txo lub tsev load. Txawm hais tias aluminium alloy yog sib zog dua hlau, nws lub zog siab tso cai rau nws tiv taus ntau dua yam tsis muaj deforming yooj yim. Haum rau tej yaam num uas xav tau siab rau lub teeb yuag, corrosion kuj, thiab zoo nkauj.
Galvanized keel: Galvanized keel feem ntau hnyav dua li aluminium alloy keel, tab sis vim yog lub zog ntawm nws cov hlau matrix, nws muaj qhov muaj zog load-cov kabmob muaj peev xwm, ua rau nws tsim nyog rau lub tsev nrog lub zog siab.
4. Tus nqi
Aluminium Alloy Keel: Vim yog cov nqi ntau dua ntawm cov ntaub ntawv txhuas alloy, aluminium alloy keels feem ntau kim dua. Yog li ntawd, aluminium alloy keels yog tsim nyog rau siab -kawg tsim tej yaam num nrog siab xav tau kev zoo thiab zoo nkauj.
Galvanized keel: Galvanized keels kuj pheej yig thiab pheej yig dua. Vim lawv cov nqi kom zoo dua, galvanized keels feem ntau yog siv nyob rau hauv nruab nrab - mus rau -qis - qhov kawg kev tsim kho tej yaam num, tsim nyog rau kev tsim kho ib puag ncig nrog kev siv nyiaj tsawg.
5. Kev zoo nkauj
Aluminium Alloy Keel: Aluminium alloy keels muaj kev kho mob zoo heev. Kev kho kom zoo nkauj dua tuaj yeem ua tiav los ntawm cov txheej txheem anodizing lossis txau, ua rau lub ntsej muag du thiab zoo nkauj zoo nkauj piv rau galvanized keels.
Galvanized Keel: Galvanized keel nto feem ntau yog nyiaj -dawb. Txawm hais tias galvanizing muab kev tiv thaiv, nws cov tsos tsis zoo li aluminium alloy keels, tshwj xeeb tshaj yog nyob rau hauv qhov chaw uas yuav tsum muaj cov qauv zoo nkauj, qhov twg aluminium alloy keels yuav tsis txaus siab.
6. Kev txhim kho thiab tu
Aluminium Alloy Keel: Aluminium alloy keels yog yooj yim rau txheej txheem thiab nruab, tsis tshua muaj kev cuam tshuam rau sab nrauv ib puag ncig, muaj lub neej ua haujlwm ntev, thiab yuav tsum tau saib xyuas tsawg dua. Galvanized keel: Cov txheej txheem kev teeb tsa rau galvanized keel zoo ib yam li aluminium alloy keel, tab sis yuav tsum tau saib xyuas tshwj xeeb rau kev saib xyuas kom raug thiab tshuaj xyuas nyob rau hauv siab -cov av noo ib puag ncig los tiv thaiv corrosion ntawm galvanized txheej.
Cov ntsiab lus
Aluminium alloy keel: Tsim nyog rau kev tsim kho cov haujlwm uas yuav tsum tau ua kom zoo nkauj, tiv thaiv corrosion, thiab kav ntev, tshwj xeeb tshaj yog ua tau zoo nyob rau hauv qhov chaw ntub dej thiab siab -kawg kho kom zoo nkauj tej yaam num.
Galvanized keel: Tus nqi qis dua, tsim nyog rau kev tsim kho vaj tsev zoo tib yam, tshwj xeeb tshaj yog nyob rau hauv cov chaw uas xav tau lub zog siab thiab qhov chaw qhuav qhuav.
Kev txiav txim siab siv aluminium alloy keel lossis galvanized keel yuav tsum tau ua raws li cov kev xav tau tshwj xeeb ntawm qhov project, pob nyiaj siv, ib puag ncig, thiab kev xav kom zoo nkauj.
