Cov hlau uas tsis yog-ferrous, tseem hu ua non-ferrous hlau, yog cov ntsiab lus sib sau ua ke rau txhua yam hlau tshwj tsis yog hlau, manganese, thiab chromium; Kev hais lus dav dav, cov hlau tsis muaj hlau kuj suav nrog cov hlau tsis muaj hlau (alloys tsim los ntawm kev ntxiv ib lossis ob peb lwm cov ntsiab lus rau cov hlau tsis-ferrous matrix (feem ntau ntau dua 50%)).

Vim li cas aluminium yog hlau ya?
Aluminium muaj qhov ntom ntom ntawm tsuas yog 2.7g / cm³, thiab muaj qhov ntom ntom Al₂O₃ zaj duab xis rau saum npoo, uas tiv thaiv cov txhuas sab hauv los ntawm kev ua haujlwm thiab tsis yooj yim oxidized. Nws yog cov khoom siv dav siv dav hlau, thiab 70% ntawm cov dav hlau niaj hnub no yog ua los ntawm txhuas thiabaluminium alloys, yog li ntawd nws yog hu ua ya hlau.

Vim li cas aluminium trivalent?
Cias muab, kev npaj ntawm electrons sab nraum aluminium atoms yog 2, 8, 3.
Cov xov tooj hluav taws xob sab nraud tsis txaus, cov qauv tsis ruaj khov, thiab peb lub tshuab hluav taws xob tau yooj yim ploj, yog li lawv feem ntau tshwm sim tsis zoo. Txawm li cas los xij, nws pom tseeb tias peb lub tshuab hluav taws xob ruaj khov dua li cov hluav taws xob sab nraud ntawm sodium thiab ob sab sab nraud ntawm magnesium, yog li txhuas tsis muaj zog li sodium thiab magnesium.

Vim li cas aluminium profiles feem ntau xav tau kev kho saum npoo?
Yog hais tias aluminium profiles tsis kho nrog kev kho deg, lawv cov tsos tsis zoo nkauj thiab lawv muaj kev cuam tshuam rau corrosion hauv huab cua ntub, ua rau nws nyuaj rau kev ua kom zoo nkauj thiab huab cua tsis kam ntawm aluminium profiles hauv cov khoom siv hauv tsev. Txhawm rau txhim kho cov teebmeem zoo nkauj, txhim kho kev tiv thaiv corrosion, thiab txuas ntxiv lub neej kev pab cuam, aluminium profiles feem ntau yuav tsum tau kho saum npoo.

Vim li cas aluminium thiaj kim dua hlau?
Txawm hais tias txhuas muaj ntau reserves nyob rau hauv lub ntiaj teb lub crust dua hlau, cov txheej txheem ntawm txhuas yog ntau complex dua hlau. Aluminium yog ib qho tseem ceeb ntawm cov hlau, thiab smelting yuav tsum tau electrolysis. Tus nqi ntawm tag nrho cov txheej txheem ntau lawm yog siab dua li ntawm cov hlau, yog li tus nqi ntawm txhuas yog siab dua li ntawm cov hlau.

Vim li cas cov kaus poom dej qab zib siv cov kaus poom txhuas?

Aluminium cov kaus poom muaj qhov zoo hauv qab no: lawv tsis yooj yim tawg; Lub teeb; Tsis translucent.

Wang Laoji, Babao Congee, thiab lwm yam yog ua los ntawm cov kaus poom hlau nyuaj, vim tias cov khoom ntim tsis muaj qhov siab, thiab cov kaus poom aluminium yog yooj yim deform. Lub siab hauv cov dej qab zib yog siab dua li qub, yog li tsis tas yuav txhawj xeeb txog kev deformation hauv qab lub siab. Thiab cov kaus poom txhuas tuaj yeem ua kom lub siab ntawm cov pa roj carbon dioxide hauv cov dej qab zib, tso cai rau cov dej qab zib kom ua tiav cov txiaj ntsig zoo dua.

Dab tsi yog kev siv ntawm aluminium?
Aluminium muaj ntau lab ntawm kev siv, tab sis hauv cov ntsiab lus, nws feem ntau muaj cov kev siv loj hauv qab no:
Cov ntaub ntawv txhuas yog siv hauv aviation thiab aerospace los ua cov tawv nqaij dav hlau, fuselage thav duab, kab teeb, rotors, propellers, roj tso tsheb hlau luam, phab ntsa panels, thiab tsaws iav ncej, nrog rau lub nkoj, foob pob ua ntxaij forging rings, spacecraft phab ntsa panels, thiab lwm yam. nyob rau hauv ntim cov dej haus, zaub mov, tshuaj pleev ib ce, tshuaj, luam yeeb, cov khoom lag luam, thiab lwm yam. Aluminium cov ntaub ntawv rau kev thauj mus los tuaj yeem muab ntau hom aluminium alloy cov ntaub ntawv rau tsheb. Cov porous loj loj rau subways thiab lub teeb rails sau qhov sib txawv hauv tsev thiab ua tau raws li cov kev cai ntawm subway localization. Lawv yog siv rau kev tsim tsheb, tsheb ciav hlau, tsheb ciav hlau, tsheb ciav hlau neeg caij tsheb, cov neeg caij tsheb siab ceev lub cev cov khoom siv, lub qhov rooj thiab qhov rais thiab cov khoom thauj khoom, tsheb cav qhov chaw, cua txias, radiators, lub cev panels, log hubs, thiab cov khoom siv nkoj. Cov khoom siv txhuas siv rau kev ntim khoom yog lub cim ntawm lub teb chaws cov txheej txheem txhuas, uas yog tsim los ntawm txhuas cov kaus poom.

Aluminium feem ntau yog siv rau hauv daim ntawv nyias nyias thiab cov ntawv ci ua cov khoom ntim hlau, ua cov kaus poom, lub kaus mom, lub raj mis, cov thoob, thiab cov ntawv ntim. Kev lag luam txhuas ntawv luam tawm tau hais farewell rau "cov txhuas thiab hluav taws" thiab nkag mus rau lub sijhawm ntawm "lub teeb thiab hluav taws xob" Cov ntaub ntawv txhuas rau cov khoom siv hluav taws xob feem ntau yog siv rau hauv ntau yam xws li busbars, xov hlau, conductors, hluav taws xob Cheebtsam, tub yees, cables, thiab lwm yam. Aluminium ntawv ci rau cov tshuab cua txias muaj kev sib sib zog nqus nqus kev ua tau zoo, siab zog, thiab zoo extensibility, mus txog qib. imported khoom zoo sib xws; Kev ua haujlwm siab electrolytic capacitor foil sau qhov sib txawv hauv tsev. Aluminium cov ntaub ntawv thiab aluminium alloys rau architectural kho kom zoo nkauj yog dav siv nyob rau hauv lub tsev thav duab, qhov rooj thiab qhov rais, qab nthab, hniav zoo nkauj, thiab lwm yam vim lawv zoo heev corrosion kuj, txaus lub zog, zoo heev txheej txheem, thiab vuam kev ua tau zoo.
