Durability ntawm titanium tableware
Nyob rau niaj hnub no txoj kev nrhiav kev zoo ntawm lub neej thiab noj qab nyob zoo, kev xaiv ntawm cov khoom siv tableware tau ntev dhau qhov kev ua tau zoo, dhau los ua tus qauv tseem ceeb rau kev ntsuas kev ua neej nyob. Titanium tableware, nrog nws cov khoom tshwj xeeb physicochemical, qhia tau hais tias muaj txiaj ntsig zoo dua li cov ntaub ntawv ib txwm muaj nyob rau hauv cov nqe lus ntawm kev ua haujlwm ntev, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov tsev niaj hnub thiab chaw sab nraum zoov.
Titanium's durability stems feem ntau los ntawm nws superior corrosion kuj. Cov hlau no, nrog qhov ntom ntom tsuas yog 57% ntawm cov hlau, sai sai tsim cov oxide zaj duab xis tsuas yog ob peb nanometers tuab ntawm chav tsev kub. Qhov kev thaiv ntuj no, tsim los ntawm titanium dioxide, tsis tsuas yog tiv thaiv kev sib cuag ntawm oxygen, noo noo, thiab cov substrate tab sis kuj muaj tus kheej - kho muaj peev xwm- txawm tias qhov chaw raug khawb, oxide zaj duab xis yuav rov tsim dua sai sai thaum sib cuag nrog huab cua. Kev sim cov ntaub ntawv qhia tau hais tias immersing titanium tableware nyob rau hauv acidic los yog alkaline daws nrog ib tug pH tus nqi ntawm 2-11 rau 72 teev tsis pom tej hlau ion nag lossis daus. Cov yam ntxwv no tso cai rau nws tswj hwm qhov chaw pristine txawm tias tuav cov khoom noj acidic xws li kua txiv qaub thiab kua txiv lws suav, tshem tawm cov teeb meem xeb thiab tsw ntxhiab los ntawm corrosion pom hauv cov tsoos stainless hlau tableware.
Titanium lub zog txhua yam kuj muab kev lav zoo rau nws cov kav ntev. Nws lub zog tshwj xeeb (lub zog rau qhov sib piv) yog 3.5 npaug ntawm stainless hlau thiab 1.3 npaug ntawm aluminium alloy. Qhov "lub teeb thiab muaj zog" tus yam ntxwv no tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov tableware. Siv titanium alloy chopsticks ua piv txwv, lawv lub zog khoov tuaj yeem ncav cuag 960 MPa, deb tshaj li 50-100 MPa ntawm cov xyoob zoo tib yam thiab ntoo chopsticks. Txawm hais tias poob los yog tsoo los ntawm cov khoom hnyav, lawv tsuas yog ua rau me ntsis deformation tsis yog tawg. Qhov tseem ceeb tshaj, titanium muaj qhov zoo heev qis- qhov kub thiab txias, tswj nws cov ductility txawm nyob rau hauv cov kua nitrogen ib puag ncig ntawm -196℃. Cov yam ntxwv no ua rau nws nyiam cov tais diav rau qhov chaw huab cua xws li kev caij tsheb kauj vab thiab nce toj siab, thaum qhov teeb meem ntawm cov hlau zoo tib yam ua nkig ntawm qhov kub thiab txias tsis muaj nyob hauv titanium.
Lub durability ntawm titanium tableware kuj tau tshwm sim hauv nws cov hnav tsis kam thiab tiv thaiv - muaj peev xwm laus. Cov tsoos stainless hlau tableware nyhav dhau los ua npub ntawm qhov chaw tom qab 3-5 xyoos vim yog hlau ion tsiv teb tsaws. Txawm li cas los xij, oxide zaj duab xis tsim los ntawm titanium tableware los ntawm kev kho cov thev naus laus zis xws li micro-arc oxidation tuaj yeem ncav cuag qhov nyuaj ntawm HV800-1000, uas yog 3-5 npaug ntawm cov hlau tsis zoo. Qhov "ceramicized" nto tsis yog tsuas yog hnav-tiv taus thiab khawb-resistant, tab sis kuj tiv taus corrosion los ntawm ntsev tsuag, hws, thiab lwm yam corrosive. Cov piv txwv tiag tiag hauv ntiaj teb qhia tau hais tias tom qab yim xyoo ntawm kev siv tas mus li, cov oxide zaj duab xis ntawm cov phab ntsa sab hauv ntawm qee hom ntawm titanium thermos khob tseem tsis zoo, nrog rau nws cov cua sov ua haujlwm tau qis dua li 5%, thaum lub khob stainless hlau ntawm tib qhov loj pom muaj kev cuam tshuam loj hauv tib lub sijhawm.
Txuas nws daim ntawv thov, qhov ua haujlwm ntev ntawm titanium tableware yog ntxiv rau hauv nws cov nqi ib puag ncig thoob plaws nws lub neej tag nrho. Titanium muaj tus nqi rov ua dua txog li 90%, thiab lub zog noj thaum lub sij hawm rov ua dua tsuas yog 20% ntawm thawj smelting. Qhov no txhais tau hais tias tom qab ib txheej ntawm titanium tableware tau ua haujlwm tag nrho nws lub neej ntev tshaj 10 xyoo, cov khoom tseem tuaj yeem rov ua dua rau hauv aerospace qhov chaw lossis cov khoom siv kho mob, tsim qhov tseeb kaw - voj voog. Hauv kev sib piv, kev siv hav zoov ntawm cov xyoob pov tseg thiab ntoo chopsticks thiab cov teeb meem microplastic pollution ntawm yas tableware yog qhov tshwj xeeb tshaj yog thaum piv rau titanium.
Saib mus rau yav tom ntej, qhov zoo dua qub ntawm titanium tableware txuas ntxiv nrog kev nce qib hauv cov ntaub ntawv tshawb fawb. Titanium alloys kho nrog nanocrystalization thev naus laus zis tuaj yeem ua kom lawv lub zog ntxiv los ntawm 30%, thaum daim ntawv thov cov txheej txheem tshiab tso cai rau qhov tawv tawv kom dhau HV1200. Cov kev siv thev naus laus zis no tsis yog tsuas yog txuas ntxiv lub neej ntawm cov tais diav tab sis kuj nthuav dav nws daim ntawv thov ciam teb-los ntawm siab- cov thawv tiv thaiv rau qhov tob- hiav txwv sojntsuam mus rau cov khoom siv rau Mars rovers, titanium lub durability tau ua pov thawj tag nrho hauv cov cheeb tsam huab cua. Rau cov neeg siv khoom uas ua raws li txoj kev ua neej zoo, xaiv titanium tableware tsis yog xaiv cov cuab yeej hauv chav ua noj uas yuav kav ntev dua 10 xyoo, tab sis kuj tseem muaj kev pov npav ntawm kev ntseeg siab hauv kev tsim kho thoob ntiaj teb.
