High Quality Hlau Of Elevator Safety Fire Door Chaw tsim tshuaj paus

Raws li cov khoom siv hlau hnyav, aluminium alloys tau pom muaj txiaj ntsig zoo hauv ntau qhov chaw. Cov hauv qab no yog cov txiaj ntsig tseem ceeb ntawm aluminium alloys:

Lub teeb:
Qhov ntom ntawm aluminium alloys yog ze li ntawm 2.7g / cm³, uas yog kwv yees li 1/3 ntawm cov hlau los yog tooj liab, uas ua rau cov khoom ua los ntawm txhuas alloys sib zog thiab yooj yim rau nqa thiab thauj.
Piv txwv li, hauv kev lag luam aerospace thiab kev lag luam tsheb, kev siv cov khoom siv aluminium alloy tuaj yeem txo qhov hnyav ntawm lub dav hlau thiab tsheb, txhim kho roj efficiency thiab kev ua tau zoo.

Siab zog:
Tom qab qee qhov kev ua haujlwm txias lossis kev kho cua sov, lub zog ntawm matrix tuaj yeem ua kom muaj zog, thiab qee qib ntawm aluminium alloys tseem tuaj yeem ntxiv dag zog los ntawm kev kho cua sov.
Aluminium alloys muaj lub zog-rau-hnyav piv, sib dua li cov hlau tab sis muaj lub zog zoo sib xws, thiab tsim nyog rau kev tsim cov khoom siv uas dais loj.

Zoo corrosion kuj:
Qhov tuab thiab khov kho txhuas oxide (al₂o₃) zaj duab xis tiv thaiv tau yooj yim tsim rau saum npoo ntawm aluminium alloys, uas tuaj yeem tiv thaiv zoo matrix ntawm corrosion.
Nyob rau hauv ib puag ncig marine, aluminium alloys tuaj yeem tiv thaiv kev yaig ntawm cov dej ntsev, yog li lawv tau siv dav hauv cov nkoj thiab cov qauv hauv hiav txwv.

Zoo hluav taws xob thiab thermal conductivity:
Cov hluav taws xob thiab thermal conductivity ntawm txhuas yog thib ob tsuas yog nyiaj, tooj liab thiab kub, thiab nws yog ib qho zoo heev thermal thiab hluav taws xob conductive khoom.
Nyob rau hauv cov khoom siv hluav taws xob, cov hluav taws xob hluav taws xob siab ntawm aluminium alloy pab kom muaj kev ruaj ntseg ntawm cov khoom siv tam sim no thiab txhim kho kev ua tau zoo thiab ruaj khov ntawm cov khoom siv.

Yooj yim rau txheej txheem:
Tom qab ntxiv qee cov ntsiab lus alloying, aluminium alloy tuaj yeem tau txais kev ua haujlwm zoo thiab ua cov yas.
Aluminium alloy tuaj yeem tsim los ntawm ntau yam kev ua haujlwm xws li extrusion, casting, forging, thiab lwm yam kom tau raws li cov qauv tsim ntawm ntau yam khoom.

Kev tiv thaiv ib puag ncig thiab txuag hluav taws xob:
Aluminium alloy yog cov khoom siv rov ua dua tshiab nrog lubricity zoo, uas tuaj yeem txo lub zog noj thiab siv lub tshuab thaum ua haujlwm.
Kev rov ua dua tshiab thiab rov siv dua ntawm aluminium alloy pab txo qhov kev thov rau cov khoom siv ntuj tsim thiab txo cov emission ntawm pov tseg, uas ua tau raws li cov kev cai ntawm kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov.
