Dab tsi yog cov kev siv cov kev lag luam tseem ceeb ntawm cov nplooj ntawv aluminium hauv kev tsim khoom niaj hnub?
Aluminium nplooj ntawv yog qhov dav nyob hauv Aerospace rau cov tawv ntoo thiab cov khoom siv dav hlau vim lawv lub zog siab tshaj plaws. Kev lag luam automotive ntiav lawv rau lub cev panels, cov ntoo khaub ncaws, thiab lub qhov rooj kom txo lub tsheb hnyav thiab txhim kho kev ua haujlwm tsheb. Hauv kev tsim kho, cov ntawv nyeem txhuas ua cov vov tsev, cladding, cladding, thiab cov ntaub thaiv phab ntsa vim tias lawv corrosion tsis kam thiab kav ntev. Lub ntim kev lag luam siv cov nplooj ntawv nyias nyias rau cov thawv ntim khoom noj thiab cov khoom siv khoom siv rau lawv cov teeb meem. Ib qho ntxiv, lawv tseem ceeb hauv cov khoom siv hluav taws xob rau cov cua sov thiab cov txheej txheem chassis tiv rau cov thermal zoo heev.
Yuav ua li cas npau taws tsim (o, h, t) cuam tshuam cov ntawv tso cai txhuas cov ntawv tso cai hauv cov ntawv thov sib txawv?
O-Tem (Annealed) Cov ntawv qhia qhov siab tshaj plaws rau cov ntawv thov sib sib zog nqus li cov qhob noom cookie raug. H-Temper (Strain-hardened) cov nplooj ntawv muab cov kev siv hluav taws xob ntawm cov qauv xws li cov ciav hlau tsheb. T-Taus (cua sov) H32 Tem npau taws ib qho sib npaug ntawm lub zog thiab daim ntawv tsim nyog rau cov laj kab dav dav. Cov Tempers sib txawv pub cov tshuab sib txawv kom pom tseeb cov khoom siv rau cov kev thov tshwj xeeb.
Cov txheej txheem kev kho mob li cas tau txhim kho cov ntawv qhia ua haujlwm hauv cov chaw hnyav?
Anodizing tsim cov tuab, tiv thaiv oxide txheej tagnrho rau cov ntawv sau architural nthuav tawm huab cua. Hmoov txheej muab cov kav dej ruaj khov, xim ceev ceev tag rau signage thiab tsev facades. Cov tshuaj lom neeg cov txheej txheem txheej txheem txheej txheem txhim kho cov xim nplaum rau lub cev tsheb lub cev. Txhua yam polishing ua tiav cov laj thawj pom zoo rau lub teeb pom kev zoo thiab cov khoom hniav zoo nkauj. Cov kev kho mob no tuaj yeem txuas txoj kev pabcuam txuas ntxiv ntawm lub neej los ntawm 3-5 lub sij hawm nyob rau hauv cov chaw muaj ib puag ncig muaj piv rau qhov chaw tsis kho.
Vim li cas cov ntawv nyeem aluminium nyiam tshaj cov hlau rau cov ntawv thov kev thauj mus los?
Aluminium nplooj ntawv hnyav txog ib feem peb ntawm cov qauv hlau sib piv, txo cov roj kev siv roj hauv tsheb. Lawv qhia tau superior corrosion tsis kam, tshem tawm cov kev xav tau rau kev kho ntshav kim kim. Aluminium lub zog siab dua-rau-lub zog piv tso cai rau thanner gauges thaum khaws cov qauv txheej txheem kev ntseeg siab. Cov khoom siv lub zog zoo nqus ua rau nws zoo tagnrho rau kev sib tsoo tswj cov tshuab. Tsis tas li ntawd, cov nplooj ntawv txhuas kom muaj cov khoom siv zoo dua ntawm cov kev siv kub heev tau ntsib hauv kev thov ib lub chaw thov kev lag luam.
Yuav ua li cas cov txheej txheem xaiv alloy sib txawv sib txawv ntawm daim ntawv thov txhuas thiab daim ntawv thov txhuas?
Cov ntawv thov architecture ua ntej tshaj plaws alloys zoo li 3003 thiab 5005 rau lawv cov lus teb zoo nkauj thiab cov ntsej muag kom zoo nkauj. Cov ntawv thov kev nyiam ua kom haum siab dua-muaj zog alloys xws li 5083 thiab 6061 rau kev thauj khoom-coj kev muaj peev xwm. Huab cua kev xaiv drives alloy xaiv rau sab nrauv vajtse panels, thaum weldability yog qhov tseem ceeb rau cov qauv txheej txheem. Cov nqi xaiv feem ntau ua rau cov kev xaiv Alloy sib txawv yuav siv Hwm cov txheej txheem ua tiav zoo ua kom muaj zog zog zog-per-duas las. Thermal Cov yam ntxwv nthuav tawm tseem cuam tshuam tseem cuam tshuam, nrog kev xaiv vaj tse uas tau xav tau zoo dua sab nraud thoob plaws.
