Nrog rau txoj kev loj hlob ntawm cov khoom siv science, muaj ntau thiab ntau hom pots hauv chav ua noj. Raws li cov ntaub ntawv, lawv tuaj yeem muab faib ua cov lauj kaub hlau, txhuas lub lauj kaub, cov lauj kaub hlau tsis muaj steel, cov lauj kaub titanium, thiab lwm yam. Ntawm cov lauj kaub hlau ntau, qhov twg yog qhov zoo tshaj plaws kev ua tau zoo thiab tsim nyog rau kev siv hauv lub neej txhua hnub?
Qhov hnyav ntawm lub lauj kaub
Feem ntau hais lus, qhov hnyav ntawm txhuas thiab titanium pots yog sib dua li cov hlau thiab stainless hlau lauj kaub. Nyob rau hauv tib lub ntim, aluminium pots yog sib dua li titanium pots. Vim tias qhov ceev ntawm titanium yog 4. Rau cov poj niam uas tsis tshua muaj zog, aluminium pans thiab titanium pans yooj yim dua rau tus tswv, txawm tias koj khaws lub lauj kaub thiab do kib.
Corrosion tsis kam ntawm lub lauj kaub
Raws li peb txhua tus paub, cov lauj kaub hlau zoo tib yam yooj yim heev rau xeb thiab corrode. Txhawm rau tiv thaiv xeb, qee cov tuam txhab lag luam yuav siv txheej txheej ntawm lub lauj kaub hlau. Titanium pots, aluminium pots thiab stainless hlau lauj kaub tuaj yeem ua rau cov pa oxygen hauv huab cua los tsim cov yeeb yaj kiab oxide ntom ntom ntawm lub lauj kaub kom tiv thaiv cov kua hauv lub lauj kaub los ntawm eroding ntawm lub lauj kaub. Tsis tas li ntawd, titanium muaj kev tiv thaiv corrosion zoo heev, thiab txawm tias cov kua qaub thiab cov pa phem heev xws li dej hiav txwv, aqua regia, thiab cov roj chlorine nyuaj rau corrode, uas nyuaj rau txhuas, hlau lossis stainless hlau.
Thaum tshav kub kub tsis kam ntawm lub lauj kaub
Thaum tshav kub kub tsis kam txhais tau hais tias cov hlau tseem tuaj yeem tswj hwm nws lub cev zoo thiab cov khoom siv kho tshuab ntawm qhov kub thiab txias. Lub sijhawm no, kev ua haujlwm ntawm titanium pots thiab stainless hlau lauj kaub yog qhov zoo dua. Piv txwv li, txawm hais tias lub melting point ntawm hlau yog 1538 degree, nws yog ib qho yooj yim heev rau undergo ib tug nruj oxidation tshuaj tiv thaiv nrog oxygen tom qab cua sov los tsim hlau oxides. Aluminium yog ib yam hlau uas muaj kev kub ntxhov, tab sis lub melting point ntawm txhuas tsuas yog 660 degree C, uas yooj yim rau soften ntawm qhov kub thiab txias. Lub melting point ntawm titanium yog 1668 ± 4 degree, thiab nws cov tshuaj muaj zog ruaj khov nyob rau hauv 500 degree; 304 thiab lwm yam zoo stainless hlau muaj hlau xws li npib tsib xee thiab chromium, uas tuaj yeem tiv taus kub ntawm 800 degree.
Thermal conductivity ntawm lub lauj kaub
Rau cov lauj kaub siv los ua zaub thiab mov, thermal conductivity yog ib qho tseem ceeb heev qhia. Lub thermal conductivity ntawm txhuas yog 237 W / mK, hlau yog 80 W / mK, titanium yog 14.63W / mK, thiab stainless hlau yog 17W / mK, qhov ntau dua qhia tau hais tias thermal conductivity zoo dua. Txawm hais tias lub thermal conductivity ntawm titanium hlau yog qis dua li ntawm txhuas thiab hlau, vim qhov zoo heev corrosion kuj ntawm titanium, phab ntsa thickness ntawm lub lauj kaub yuav txo tau zoo heev, thiab lub tshav kub pauv ntawm qhov chaw thiab cov chav yog dropwise condensation, uas txo cov thermal kuj. Tsis muaj scaling tseem tuaj yeem txo cov thermal tsis kam, yog li cov thermal conductivity ntawm titanium yog qhov zoo dua.
Lub lauj kaub noj qab haus huv thiab kev nyab xeeb
Txawm hais tias cov lauj kaub hauv chav ua noj tuaj yeem tiv taus corrosion thiab kub kub rau qee qhov, hlau yuav inevitably precipitate lub sij hawm. Kuj tseem muaj kev pheej hmoo ntawm nag lossis daus ntawm txhuas hauv cov lauj kaub aluminium uas tau siv ntev. Aluminium tuaj yeem ua rau tib neeg lub hlwb puas tsuaj, yog li nws muaj kev phom sij ntau dua. Stainless hlau muaj cov hlau hnyav xws li nickel thiab chromium. Yog tias muaj nag lossis daus ntawm hlau, nws tuaj yeem ua rau muaj kab mob lom.
Cov lauj kaub hlau feem ntau yog ua los ntawm npua hlau, uas muaj qhov zoo ntawm yuav luag tsis muaj cov hlau hnyav uas muaj kev phom sij rau tib neeg lub cev thiab ruaj khov. Tom qab siv mus ntev, hlau yog precipitated, tab sis nws tsis tshua muaj teeb meem rau tib neeg lub cev. Titanium yog ib qho kev noj qab haus huv "biological hlau" lees paub los ntawm cov zej zog kev tshawb fawb. Nws yog non-toxic thiab muaj kev sib raug zoo nrog tib neeg cov ntaub so ntswg thiab ntshav. Yog li ntawd, cov lauj kaub ua los ntawm titanium tuaj yeem hais tias noj qab nyob zoo thiab tsis muaj mob.
Yuav kom suav tau, cov lauj kaub ntawm txhua cov khoom siv hlau muaj lawv tus kheej zoo. Txawm li cas los xij, nrog kev paub txog kev noj qab haus huv ntawm tib neeg, kev noj qab haus huv thiab kev nyab xeeb ntawm lub lauj kaub maj mam dhau los ntawm kev ua kom sov, thermal conductivity, thiab corrosion kuj los ua thawj yam hauv kev yuav cov lauj kaub. Tsis tas li ntawd, tag nrho cov kev ua tau zoo ntawm titanium yog qhov zoo heev, yog li titanium pots Nws tau dhau los ua qhov kev xaiv zoo tshaj plaws rau ntau tus neeg ua noj.
