Tuaj yeem titanium withstce dej npau npau
Hauv peb lub nrawm - paced lub neej niaj hnub, Thermoses tau ntev dhau los ua lub neej txhua hnub. Los ntawm thawj khob dej sov thaum sawv ntxov rau haus kev ua kis las thaum sab nraum zoov, tib neeg muaj peev xwm xav tau cov ntaub ntawv thiab kev ua tau zoo ntawm lawv cov thermoses. Among numerous metal materials, titanium, due to its unique physical and chemical properties, is gradually emerging as a leader in high-end drinking water equipment. Yog li, tuaj yeem no cov khoom siv no, feem ntau hu ua "chaw hlau," tiv thaiv kev kuaj ntawm cov dej npau? Cov lus teb nyob hauv nws cov microstructure, thermodynamic zog, thiab kev lag luam tsim khoom.
Kev tiv thaiv ntuj los ntawm oxide zaj duab xis
Titanium lub corrosion tsis kam ntawm cov xim ntawm cov yeeb yaj kiab xim tuab uas cov ntaub ntawv ntawm qhov chaw. Nyob rau hauv chav tsev kub, titanium sai sai reacts nrog oxygen nyob rau hauv huab cua, sib sau ib titanium dioxide (tio₂) zaj duab xis tsuas yog 2-10 nanometers tuab. Qhov qauv oxide oxide, nrog nws cov qauv ruaj khov thiab cov nplaum ruaj khov, ua zoo li lub ntuj "daim hlau thaiv" Cov kev sim tau qhia tias titanium tswj hwm nws cov qauv txheej txheem hauv cov thwj me acid, thiab nws txoj kev txhim kho dog acid, thiab nws cov kev sib raug zoo ntawm cov hlau uas zoo li cov hlau tsis zoo li qub.
Thaum cov dej npau npau rau hauv lub titanium thawv, cov oxide zaj duab xis tsis tsuas yog txwv tsis pub siv cov dej txuas nrog cov microorganisms mus rau lub khob phab ntsa. Kev tshawb fawb tau pom tias micride zaj duab xis nyob rau hauv titoolium deg muaj cov khoom siv tshuaj tua kab mob, rhuav tshem cov kab mob cell cov kua thiab ua tiav kev txwv ntawm lub cev. Qhov no ob lub tshuab sib zog sib zog tiv thaiv kev tso cov khoom muaj teeb meem thaum cov thawv rhaub kom muaj sijhawm ntev, thaum tswj cov dej zoo.
Precision tswj cov cua sov
Titanium muaj lub ntsiab lus melting ntawm 1668 degree, tab sis tus qauv txheej ntawm ob {1} {1} {khob ntsib kev sib tw ntawm lub cev ntawm thermal expansion thiab condaction. Thaum cov dej npau npau (95 degree) tau hliv rau hauv qhov qis - kub titanium khob, lub khob lub cev thiab lub nqus plua plav txheej ua kom qhuav. Los ntawm kev suav meej, cov tuam ntxhab tau tswj hwm lub phab ntsa tuab ntawm Titanium khob rau ntawm 0.3 thiab 0.5 mm, kom muaj kev ntxhov siab thermal rau lub nqus txheej. Kev sim cov ntaub ntawv qhia tau hais tias nyob rau hauv cov kev hloov pauv kub ntawm {}} Cov txheej txheem me me (tsawg dua 0.1 tus nqi tseem ceeb uas cuam tshuam thermal rwb thaiv tsev ua haujlwm. Cov qauv tsim no yog raws cov kev nkag siab zoo ntawm titefficient ntawm thermal expansion {qhov no ntawm stainless hlau, ua rau nws ruaj khov tsis ruaj khov nyob rau hauv kub hloov pauv. Tsis tas li ntawd, lub tshuab nqus-txheej ob npaug ntxiv ua kom muaj kev ua tiav los ntawm kev thaiv kev ua haujlwm kub, ua tiav cov nyhuv ntawm "dej npau tseem kub tom qab 12 teev."
Kev yoog raws li acidic thiab alkaline ib puag ncig
Hauv cov xwm txheej haus txhua hnub, cov dej npau npau yog feem ntau tov nrog dej acidic xws li tshuaj yej thiab kas fes. Titanium tus oxide zaj duab xis kev ua yeeb yam zoo tshaj plaws nyob rau hauv acidic acidic ib puag ncig. Kev ntsuas kev sim simulating simulating ntev- lub cav ntsawj noj nag lossis cov roj hmab uas tsis muaj dej nag los nag li cas? Qhov sib txawv no yog vim titanium lub zog passivation cov khoom: txawm hais tias tus oxide zaj duab xis yog thaj chaw puas nrawm nrog oxygen kom kho cov qauv zaj duab xis. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias titanium tau txwv tsis pub muaj zog acids. Cov tshuaj fluoride xws li cov acid Txawm li cas los xij, nyob rau hauv ib txwm haus cov xwm txheej kev haus, raug rau xws li muaj zog acids yog tsawg kawg nkaus. Rau cov dej qaug zog acidic zoo li kas fes thiab tshuaj yej, titanium khob muaj kev corrosion {{ove} tiv taus thiab yuav tsis cuam tshuam rau cov tsw.
Cov Khoom Siv Purity thiab Manufacturing Txheej Txheem
Siab -}}}}% purity titanium (ntau dua los yog sib npaug ntawm lub tshuab nqus dej Nqus plua plav vuam vuam tshem tawm micrracks micrappacks micrmacks nyob rau hauv Weld Seam, tiv thaiv kev pheej hmoo ntawm kev so dej poob siab. Saws kev sib tw siv kev sib tw zuj zus los kho lub khob lub khob uas muaj zog, txhim kho lub zog thiab corrosion tsis kam.
Thaum lub sijhawm ntsuas kev ua haujlwm, titanium khob yauv mus ncig ua si npau npau (100 teev) thiab kev sim siab hloov ntawm ib qho siab ntawm 5,000 metres) kom ntseeg tau tias lawv cov xwm txheej ruaj khov. Kev kho cov npoo xws li ib qho anodizing tuaj yeem txuas ntxiv cov yeeb yaj kiab oxide ntxiv, txhim kho lub khob hnav tsis kam thiab ua kom zoo nkauj.
Los ntawm kev kuaj cov ntaub ntawv rau kev tsim qauv, los ntawm cov khoom siv rau cov txheej txheem kev tsim khoom, lub titanium khob ua rau cov dej npau tau txais kev nkag siab. Qhov no "qhov chaw hlau," keeb kwm los ntawm Aerospace kev lag luam, yog rov qab siv dej haus niaj hnub nrog nws txoj kev nyab xeeb, durability, thiab ib puag ncig phooj ywg. Thaum peb siv lub khob titanium kom brew ib lub lauj kaub cov tshuaj yej kub hauv lub khob, tab sis kev txawj ntse ntawm kev sib haum xeeb ntawm thev naus laus zis thiab xwm.
