Cov phiaj hlau tau siv los ua cov khoom vov tsev rau ntau pua xyoo. Cov hlau ntau ntawm cov khoom siv los ua cov ntaub ntawv vov tsev yog feem ntau vim txoj kev loj hlob sai ntawm lub ntiaj teb' s metallurgical kev lag luam txij li xyoo 1960, uas tuaj yeem tsim tau ntau yam kev qhia tshwj xeeb thiab ua tau raws li cov kev xav tau zoo. , Thiab txo tus nqi.
Hlau vov tsev cov ntaub ntawv mas suav nrog galvanized steel phaj, stainless hlau phaj, aluminium alloy phaj, phaj tooj liab, zinc tooj liab titanium plywood thiab ntshiab titanium phaj. Qhov zoo ntawm sheet hlau vov tsev yog yooj yim tsim kho, nrawm nrawm, zoo dej tsis ua haujlwm, thiab rov siv tau dua. Ntxiv rau qhov muaj peev xwm tiv taus qhov siab tshaj thiab qis tshaj qhov kub uas lub ntiaj teb' s kev nyab xeeb tuaj yeem tsim, nws tsis tshua muaj kev cuam tshuam los ntawm kev ntxhov siab los ntawm huab cua thiab ru tsev deformation thaum siv los ua cov ntaub ntawv vov tsev. Cov neeg tuaj yeem tuaj yeem thov ntau cov xim ntawm cov xim raws li cov xwm txheej.
Aluminium-magnesium-manganese alloy board ru tsev / kab hlau rhuav phab ntsa system siv feem ntau 3000 series ntawm txhuas-manganese (txhuas-manganese) alloys. Lub elongation, hardness, tensile lub zog, tawm los muaj zog thiab lwm yam ntsuas ntawm 3000 series ntawm aluminium-manganese alloys yog heev haum rau ru tsev crimping, Ua ntawm cov khoom siv dov. Yog li ntawd, nws yog dav siv nyob rau sab nrauv kho tej yaam num xws li lub ru tsev / phab ntsa tshuab, thiab nrog ntau cov txheej txheem tha xim thiab txheej txheej txheej, cov tsos ntawm lub tsev ua xim zoo nkauj, thiab qhov chaw tiv thaiv corrosion ntawm aluminium alloy nws tus kheej tau nce.
Qhov tsawg kawg nkaus tuab ntawm cov khoom siv txhuas siv rau lub ru tsev yog 0.7 hli. Thaum lub thickness ntawm txhuas khoom yog 1 hli, nws qhov hnyav yog 2.7 kg / m2, thiab thaum lub thickness 0.7 hli, qhov nyhav ntawm cov khoom siv aluminium yog 1,89 kg / m2. Qhov ntev ntawm lub kauj tsis txwv.
Nws cov yam ntxwv tseem ceeb yog: ntom ntawm 2.7, lub ntsiab lus ploj ntawm 658, linear expansion coefficient ntawm 0.0000023 ntawm qhov kub ntawm 20-100 degrees, tawg load coefficient ntawm 8-12 kg / mm2 (sib txawv raws li qhov nyuaj ntawm cov khoom), thiab elongation ntawm 10 ～ 40%, qhov tuab yog 0.7 ～ 1.2 hli. Thaum nws yog aluminium corrugated board, lub thickness tuaj yeem txo mus rau 0.6mm. Ntxiv nrog rau crimping thiab rivet kho, vuam kuj tuaj yeem saws tau.
1. Kev sib piv ntev ntev: Aluminium-magnesium-manganese alloy tuaj yeem tsim zaj duab xis aluminium oxide nrog rau cov huab cua kom tiv thaiv kev xeb ntxiv. Feem ntau, nws muaj txheej txheej tiv thaiv li ntawm 15-20 xyoo thaum siv hauv cov tsev haujlwm. Kev tsim cov kev pabcuam lub neej ntawm lub tsev yog ntau tshaj 50 xyoo. Feem ntau, khoom lav 25-xyoo tau lees tias; xim steel daim hlau tau yooj yim corroded thiab xeb nyob rau hauv kev yaig ntawm huab cua noo, nag thiab daus, thiab ua rau muaj kev sib tsoo, tshwj xeeb tshaj yog cov rivets thiab pob qij txha.
2. Kev sib piv qhov hnyav: aluminium-magnesium-manganese alloy yog lub teeb nyob hauv qhov hnyav (ceev yog 2730 kg / m²); xim xim steel phaj yog qhov hnyav (qhov ceev yog 7850 kg / m²)
3. Sib piv ntawm lub zog thiab tawv tawv: Cov txhuas ntawm cov txhuas-magnesium-manganese alloy muaj cov ntsiab lus magnesium thiab manganese, yog li nws muaj qee yam muaj zog thiab nruj. Txawm li cas los xij, sab hauv kev ntxhov siab, ua kom tawv tawv, thiab lub zog ntawm aluminium alloy daim hlau tsis muaj qhov pom tseeb qhov taw qhia, uas tsis zoo li xim hlau; xim hlau daim hlau muaj qhov zoo dua thiab kev nruj thiab tsis yooj yim rau deform.
4. Txawv sib piv: txhuas-magnesium-manganese alloy tuaj yeem faib ua cov tsis muaj xim (hammer qauv, embossing, pre-passivated alumina deg kho, thiab lwm yam) thiab pleev xim (PVDF, SMP, PE, thiab lwm yam); xim xim hlau phaj tuaj yeem muab faib ua cov xim tsis muaj xim (kub-dip aluminium-zinc alloy steel sawb: pawg thawj coj saib) thiab pleev xim (PVDF, SMP, PE, HDP, thiab lwm yam).
5. Kev ua haujlwm ntawm kev tiv thaiv xob laim: lub thickness ntawm aluminium-magnesium-manganese alloy feem ntau 0.7 hli thiab 0.9 hli, uas tuaj yeem siv ncaj qha raws li xob laim thaiv kev tiv thaiv huab cua tawm suab ntaus ntawv (Lub Teb Chaws Txoj Cai" Code rau Tsev Kev Tiv Thaiv Tsim Tsa Tsim" GB50057) kom tsis txhob cuam tshuam ntawm lub ru tsev; xim steel phaj feem ntau 0.5 hli tuab galvanized thiab galvanized steel cov ntawv tsis tuaj yeem siv ncaj qha ua xob laim ntawm cov neeg raug ntes, thiab ntxiv rau xob laim ntes (xws li cov pas nrig hluav taws xob) yuav tsum teeb tsa.
6. Kev nyab xeeb thiab tiv thaiv hluav taws: Aluminium-magnesium-manganese alloy muaj qhov chaw tsawg kawg (660 degrees Celsius). Lub siab kub ua haujlwm tsis zoo, thiab lub zog poob sai sai thaum kub siab tshaj 150 degrees. Thaum muaj hluav taws kub, lub ru tsev yog qhov yooj yim ntawm qhov hluav taws kub, ua rau hluav taws sib kis tau sab nraud tsis txhob siv sab hauv thiab sab nraud, uas pab cov neeg tua hluav taws txuas ntxiv hluav taws kub hose los ntawm sab saum toj; melting kis ntawm xim steel phaj yog siab (1515 degrees Celsius).
7. Txoj Kev Ua: Aluminium-magnesium-manganese alloy muaj qhov zoo weldability, high plasticity, nyob rau hauv ib puag ncig tsis kub, qhov muaj zog thiab ductility ntawm aluminium alloy tau zoo dua, thiab nws muaj qhov ua haujlwm qis-kub ua haujlwm tau zoo; xim hlau phaj yog nquag ua txias txias ntawm qhov kub tsawg.
8. Tus nqi txhim kho: Aluminium-magnesium-manganese alloy tus nqi zoo dua: lub teeb yuag, tsis muaj dej, yooj yim khoov arc, thiab zoo stereoscopic pom tau zoo; xim xim steel phaj muaj qis dua kev ua haujlwm: lub nra hnyav, lub cev tsis zoo, ua haujlwm tsis zoo dabtsi yog khoov arc, kos duab ua haujlwm tsis zoo.
