Thaum xaiv cov ntaub ntawv rau kev tsim kho, kev tsim khoom, lossis DIY cov phiaj xwm, txhuas thiab hlau stainless yog ob qho ntawm cov hlau uas nrov tshaj plaws. Tab sis dab tsi raws nraim teeb lawv sib nrug? Txawm hais tias koj yog tus kws ua txuj ci, ib tug neeg nyiam ua, lossis tsuas yog xav paub, nkag siab txog lawv qhov sib txawv tuaj yeem pab koj txiav txim siab txiav txim siab. Hauv no blog, peb yuav tawg lawv cov khoom, kev siv, nqi, thiab ntxiv-rov qab los ntawm cov kws tshaj lij-los pab koj xaiv cov khoom zoo rau koj cov kev xav tau.
1. Kev sib xyaw: lawv tau ua dab tsi?
Qhov tseem ceeb sib txawv ntawm txhuas thiab stainless hlau lus nyob rau hauv lawv cov pes tsawg xyoo.
Tooj dawbyog lub teeb yuag, silver-dawb hlau pom hauv lub ntiaj teb crust. Ntshiab txhuas yog cov muag muag, yog li nws feem ntau tau sib txuam nrog cov ntsiab lus xws li tooj liab, magnesium, lossis silicon los txhim kho lub zog. Piv txwv li, cov cuab yeej siv dav 6061 alloy alloy muaj magnesium thiab silicon.
Stainless hlauyog cov hlau-based alloy muaj tsawg kawg yog 10.5% chromium, uas tsim ib txheej passive oxide los tiv thaiv corrosionCov. Cov qib kawm ib yam li 304 stainless hlau kuj muaj pes tsawg npib thiab carbon.
2. Lub zog thiab durability
Lub zog yuav tsum muaj kev sib txawv los ntawm daim ntawv thov, yog li cia peb muab lawv cov cuab yeej siv.
Stainless hlau:
Stainless hlau yog qhov muaj zog dua aluminium, tshwj xeeb tshaj yog nyob rau ib puag ncig muaj kev ntxhov siab. Piv txwv li, qib 304 stainless hlau muaj lub zog tensile ntawm ~ 505 MPa, piv rau 6061 Aluminium tus ~ 310 mpa.
Txhuas:
Thaum tsis tshua muaj zog los ntawm ntim, txhuas muaj lub zog zoo dua-ua kom muaj zog. Qhov no ua rau nws zoo tag nrho rau aerospace Cheebtsam (zoo li cov dav hlau dav hlau) thiab kev thauj mus los tsheb thauj khoom uas txo qhov hnyav yog qhov tseem ceeb.
Yog li, stainless hlau muaj zog tag nrho, tab sis txhuas txawj ntse thaum lub teeb yuag.
3. Corrosion Kuj
Ob qho me me tiv taus corrosion, tab sis lawv cov tshuab sib txawv.
Stainless hlau:
Chromium hauv stainless hlau reacts nrog oxygen los ua ib qho kev tiv thaiv cov chromium oxide txheej. Qhov txheej txheem kho nws tus kheej kho tiv thaiv xeb, txawm tias thaum khawb. Cov qib nyiam xws li 316 stainless hlau ntxiv molybdenum rau cov khoom tsis kam ntxiv rau ntsev kom dej thiab tshuaj lom neeg.
Tooj dawb:
Aluminium ib txwm ua ib txheej oxide nyias, tiv thaiv nws los ntawm oxidation. Txawm li cas los xij, nws tau zoo rau Galvanic corrosion thaum ua ke nrog cov sib npaug ntawm cov chaw muaj feem ntawm cov chaw noo noo. Anodizing lossis pleev xim tuaj yeem txhim kho nws txoj kev tiv taus.
Yog li, stainless hlau muaj ntau dua stre Strorust corrosion tsis kam, thaum cov txhuas yuav tsum muaj kev kho mob uas yuav tsum muaj cov mob hnyav.
4. Qhov hnyav: Aluminium yeej rau kev siv qoj nyuaj
Aluminium qhov ntom yog hais txog 2.7 g / cm³, tsawg dua ib feem peb ntawm stainless hlau 8 g / cm³,uas yog ib lub tsho heev.
·Cov dav hlau thiab cov khoom lag luam
·Portable Electronics (piv txwv li, khoos phis tawj)
·Cov neeg siv khoom cov khoom lag luam zoo li lub tsheb kauj vab thiab chaw pw hav zoov
Stainless hlau Heft yog qhov tau txais txiaj ntsig hauv cov ntawv thov yuav tsum muaj kev ruaj ntseg, xws li kev lag luam tshuab lossis kev tsim qauv vaj tse txhawb nqa.
5. Thermal thiab hluav taws xob conductivity
Thermal Condivity:
Txhuas ua cua sov 3x zoo dua li cov hlau tsis muaj zog, ua rau nws zoo tagnrho rau cov cua sov, cookware, thiab hvac systems.
Hluav Taws Xob Ua Haujlwm:
Txhuas yog dav siv nyob rau hauv cov hluav taws xob kab thiab cov hluav taws xob vim nws lub siab ua haujlwm (61% tooj liab lub). Stainless hlau yog tus neeg ua tus coj ua tsis tau zoo thiab tsis tshua muaj siv nyob rau hauv cov khoom siv hluav taws xob.
6. Tus nqi sib piv
Txhuas:
Feem ntau pheej yig dua li stainless hlau, nrog tus nqi compon complets raws li cov nqi zog (kev sib pauv ntau lawm yog lub zog-sib zog). Raws li ntawm 2023, cov nqi txhuas ~ $ 2,500 ib metric tuj.
Tus Hlau Stainless:
Kim kim vim muaj kev sib dhos xws li chromium thiab npib tsib xee. Qeb 304 Stainless Hlau Qhov nruab nrab ~ $ 3,000 ib Metric tuj.
Tswv yim:Rau pob nyiaj txiag-phooj ywg txoj haujlwm uas qhov hnyav teeb meem, xaiv aluminium. Txog kev thiav nyob hauv kev ua phem, stainless hlau yuav ua pov thawj cov nqi siab dua.
7. Machinability thiab kev tsim khoom
Txhuas:
Softer thiab yooj yim txiav, khoov, lossis extrude. Qhov zoo tagnrho rau cov duab nyuaj thiab profotyping sai. Txawm li cas los xij, nws tuaj yeem ua cov kob uas nce cov cuab yeej vim nws qhov kev sib tw melting.
Tus Hlau Stainless:
Harder rau lub tshuab, xav tau cov cuab yeej tshwj xeeb thiab qeeb qeeb. Txawm li cas los xij, nws tuav cov duab qhia meej thiab ua tiav zoo, foob cov khoom siv kho mob lossis cov ntsiab lus architectural.
Rau vuam, stainless hlau yuav tsum muaj roj tiv thaiv (tig / Mig), thaum Aluminium cov kev xav tau kev paub tuav kom tsis txhob sib ntaus sib tua.
8. Cov Ntawv Thov Rau
Aluminium Siv:
·Aerospace (dav hlau fuselages)
·Ntim (cov kaus poom, ntawv ci)
·Kev tsim kho (qhov rai thav ntawv, vov tsev)
·Tsheb thauj mus los (tsheb, nkoj)
Stainless hlau siv:
·Cov twj siv kho mob
·Khoom siv chav ua noj (tog, cutlery)
·Kev Siv Tso Tsheb Hlau Luam
·Marine Hardware (Nkoj Fittings)
9. Kev ua tsis tau thiab rov ua dua tshiab
Cov hlau yog 100% siv dua tshiab:
·Aluminium Thanycling txuag 95% ntawm lub zog uas yuav tsum muaj rau kev tsim khoom.
Xaus: Koj yuav tsum xaiv qhov twg?
Xaiv aluminium yog tias:
·Koj xav tau ib lub teeb yuag, cov khoom siv tau nqi.
·Thermal / hluav taws xob conductivity yog qhov tseem ceeb.
·Lub phiaj xwm tsis muaj kev ntxhov siab ntau lossis cov chaw muaj kev sib raug zoo.
Xaiv stainless hlau yog tias:
·Lub zog thiab corrosion tsis kam yog qhov tseem ceeb tshaj plaws.
·Daim ntawv thov cuam tshuam nrog cov kub lossis cov tshuaj hnyav.
·Kev thov kom zoo nkauj (piv txwv li, polished tas) teeb meem.
