1.Dab tsi yog qhov txawv ntawm cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom hauv paus?
Galvanized Coil: Lub hauv paus yog qis- carbon steel nrog zinc txheej.
Lub zog muaj zog: Feem ntau muaj zog dua li aluminium alloys.
High Hardness: Ntau hnav-resistant, tab sis kuj ua rau hnav ntau dua ntawm cov cuab yeej thiab tuag thaum ua.
High Elastic Modulus: Kwv yees li 200 GPa, uas txhais tau hais tias tseem ceeb ntawm lub caij nplooj ntoos hlav thaum khoov, yuav tsum tau tsim qauv tuag kom them rov qab.
Aluminium Alloy Coil: Cov hom muaj xws li 1000 series (ntshiab txhuas), 3000 series (Al-Mn), thiab 5000 series (Al-Mg).
Tsawg zog: Txawm li cas los xij, lub zog tshwj xeeb (lub zog / ntom) yog siab.
Tsawg Hardness: Mos thiab khawb tau yooj yim, tab sis nrog kev ua haujlwm tsawg.
Tsawg Elastic Modulus: Kwv yees li 70 GPa, uas txhais tau hais tias tsis tshua muaj caij nplooj ntoos hlav thaum khoov, ua kom yooj yim dua kom ua tiav cov kaum sab xis.
2.Kev sib piv ntawm cov txheej txheem txiav thiab xuas nrig ntaus, cov txiaj ntsig yog dab tsi?
Aluminium alloy: Kom meej meej superior. Vim nws qis zog thiab hardness, tsawg zog thiab lub zog yuav tsum tau rau shearing thiab blanking. Hnav ntawm cov tuag thiab cov cuab yeej txiav kuj tseem txo qis, ua rau lub neej ntev ntawm cov cuab yeej thiab kev ua haujlwm ntau dua.
Galvanized coil: Yuav tsum muaj lub tshuab xuas nrig ntaus thiab shearing loj dua. Cov tawv zinc txheej thiab steel substrate nrawm hnav ntawm cov npoo tuag.
3.Yuav ua li cas khoov thiab tsim cov txheej txheem sib piv?
Aluminium alloy: Kuj superior. Nws txo qis springback ua rau nws yooj yim dua rau cov neeg ua haujlwm tswj lub kaum sab xis thiab tsim cov duab. Aluminium alloy kuj ua rau nws yooj yim dua kom ua tiav qhov xav tau nkhaus rau txoj kev yob txoj kev.
Galvanized coil: Qhov kev sib tw loj tshaj plaws yog springback. Cov neeg ua haujlwm yuav tsum muaj kev paub dhau los thiab them nyiaj rau lub caij nplooj ntoo hlav los ntawm "overbending" kom ua tiav qhov tseeb 90-degree kaum. Qhov no yuav tsum muaj sijhawm ntxiv rau kev hloov kho.
4.Dab tsi yog qhov kev sib piv ntawm qhov sib sib zog nqus nqus thiab ncab?
Aluminium alloys feem ntau ua tau zoo dua. Ntau cov txhuas alloys (xws li 3003 thiab 5052) muaj cov ductility zoo heev, ua rau lawv zoo - haum rau kev sib sib zog nqus nqus thiab tsim cov khoom nyuaj (xws li cov lauj kaub thiab cov kaus poom).
Galvanized coils: Thaum lub qis- carbon steel substrate nws tus kheej kuj yog cov ductile heev, lawv muaj feem rau Lüders bands (tseem hu ua slip kab), cov kab tsis sib xws ntawm qhov chaw uas degrade zoo li. Qhov no yog yuav tsum tau zam nyob rau hauv qhov chaw uas yuav tsum tau stringent nto finishes.
5.Yuav ua li cas cov txheej txheem vuam sib piv?
Galvanized kauj: Kom meej meej superior. Galvanized steel vuam txheej txheem yog cov paub tab, tso cai rau tus qauv MAG vuam thiab qhov chaw vuam tsis kam. Cov txheej txheem no tau yooj yim muaj thiab siv tau yooj yim.
Aluminium alloy: Nws nthuav tawm cov teeb meem tseem ceeb.
The dense aluminum oxide film on the surface (melting point approximately 2050℃) is much higher than the aluminum substrate (melting point approximately 660℃), requiring high power or specialized welding techniques (such as AC TIG welding) to break it.
High -purity shielding gas (xws li argon) yog yuav tsum tau.
High thermal conductivity ua rau cov cua kub sai sai, ua kom tsis tiav kev nkag mus tsis zoo yuav tshwm sim.
Qhov siab coefficient ntawm thermal expansion ua rau muaj qhov cuam tshuam loj ntawm weld.
