Dab tsi yog qhov zoo ntawm titanium alloy eyeglass thav duab tshaj cov hlau zoo tib yam?
Ntawm cov dazzling array ntawm cov ntaub ntawv nyob rau hauv lub khw muag khoom eyewear, titanium alloy thav duab, nrog lawv "lub teeb yuag tsis tau steel- zoo li lub zog," yog maj mam dhau los ua "zoo tagnrho" xaiv rau cov neeg siv khoom. Txawm hais tias rau lub sijhawm ua lag luam zoo lossis kev txhawb nqa ruaj khov thaum lub sijhawm ua kis las, titanium alloy thav duab yeej ib txwm sawv tawm nrog lawv cov txiaj ntsig tshwj xeeb. Tab sis dab tsi tiag tiag ua rau titanium alloy zoo dua li cov hlau zoo tib yam? Hauv qab no yog ib qho kev sib sib zog nqus ntawm cov ntaub ntawv tshawb fawb, kev tsim technology, thiab ergonomics.
Lightweight Design: A "Revolution in Reducing Burden on the Bridge of the Nose"
Ordinary hlau eyewear thav ntawv feem ntau yog ua los ntawm nickel- tooj liab alloys lossis stainless hlau. These materials have a high density, and a pair of ordinary metal frames can weigh 25-30 grams, which can easily lead to pressure marks on the bridge of the nose and ear fatigue with prolonged wear. Titanium alloy, ntawm qhov tod tes, muaj qhov ceev ntawm tsuas yog 4.5 g / cm³, tsuas yog 50% ntawm cov hlau tsis muaj steel thiab 60% ntawm cov nickel alloys. Piv txwv li, ib tug ntshiab titanium thav duab tuaj yeem hnyav dua 15 grams, sib npaug rau ib nrab ntawm qhov hnyav ntawm cov hlau zoo tib yam. Lub teeb yuag no yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov neeg siv nrog siab - lo ntsiab muag tshuaj- lo ntsiab muag lawv tus kheej twb hnyav, thiab yog tias tus ncej ntxiv qhov hnyav ntxiv, hnav kev nplij siab yuav txo qis. Ib tus neeg hnav ntev ntev ntawm titanium alloy tsom iav tau tshaj tawm: "Tom qab hloov mus rau titanium alloy thav ntawv, cov cim liab ntawm kuv lub qhov ntswg choj ploj, thiab kuv tsis nkees txawm tias tom qab hnav lawv tag nrho ib hnub."
Corrosion Resistance: Ib "Kev Ntsuas Ob" ntawm hws thiab Sijhawm
Qhov kev tiv thaiv corrosion ntawm cov hlau zoo tib yam yog lawv qhov tsis muaj zog. Nickel- tooj liab alloys tuaj yeem tsim cov kab xeb tsis pub dhau 3-6 lub hlis hauv qab cov hws tawm hws; thaum stainless hlau muaj zog corrosion kuj, welded pob qij txha tseem ua rau blackening vim oxidation. Titanium alloys, ntawm qhov tod tes, nthuav tawm qhov zoo ntawm "natural corrosion resistance": titanium oxide tuab (TiO₂) tiv thaiv zaj duab xis tsim rau ntawm nws qhov chaw tuaj yeem cais cov pa oxygen, noo noo, thiab ntsev los ntawm hws. Kev sim cov ntaub ntawv qhia tau hais tias tom qab ntshiab titanium yog immersed nyob rau hauv ib tug 3.5% sodium chloride tov (simulating ib puag ncig hws) rau 1000 teev, lub nto corrosion qhov tob tsuas yog 0.001 hli, thaum lub corrosion tob ntawm npib tsib xee{11}} tooj liab alloy ncav cuag 0.05 hli. Cov yam ntxwv no tso cai rau titanium alloy thav duab kom nyob twj ywm ci thiab tshiab txawm tias nyob rau hauv qhov chaw ntub dej lossis siab - qhov kub thiab txias (xws li ntug hiav txwv dej), thiab lawv lub neej kev pabcuam tuaj yeem ua tau ntau dua peb npaug ntawm cov hlau zoo tib yam.
Lub zog thiab elasticity: Los ntawm "yooj yim deformable" mus rau "Ib puag ncig"
Lub brittleness ntawm cov hlau zoo tib yam yog lwm qhov teeb meem loj. Nickel- tooj liab alloys muaj lub zog tensile ntawm tsuas yog 400-500 MPa, thaum stainless hlau, txawm hais tias ncav cuag 800-1000 MPa, tsis muaj toughness thiab nws yooj yim tawg nyob rau hauv kev cuam tshuam. Titanium alloys, txawm li cas los xij, ua tiav qhov sib npaug ntawm lub zog thiab lub zog los ntawm kev tsim alloying: piv txwv li, -titanium alloys muaj lub zog tensile tshaj 1200 MPa, thaum lawv elastic modulus yog 40% qis dua stainless hlau. Qhov no txhais tau tias lawv tuaj yeem tiv taus ntau dua sab nraud thiab rov qab mus rau lawv qhov qub qub tom qab raug kev ntxhov siab. Ib tus neeg nyiam ua kis las tau hais tias, "Thaum kuv ua si ntaus pob thiab lub pob ntaus kuv lub tsom iav, cov hlau zoo tib yam deformed ncaj qha, thaum titanium alloy thav duab tsuas yog khoov me ntsis thiab tseem tuaj yeem siv ib txwm tom qab hloov kho." Cov yam ntxwv no ua rau titanium alloy nyiam cov khoom siv rau cov tsom iav ncaws pob thiab cov menyuam yaus lub tsom iav.
Biocompatibility: "Kev Tiv Thaiv Yooj Yim" rau cov tawv nqaij rhiab heev
Kev ua xua hlau yog ib qho kev txhawj xeeb rau cov neeg siv tsom iav. Nickel yog ib qho kev ua xua loj; kwv yees li 10% ntawm cov pej xeem hauv ntiaj teb no ua xua rau npib tsib xee, thiab kev sib cuag tuaj yeem ua rau cov tsos mob xws li tawv nqaij liab, o, thiab khaus khaus. Titanium alloys tuaj yeem ua tiav qhov purity ntau dua 99% (xws li cov titanium ntshiab) thiab tsis muaj teeb meem xws li npib tsib xee thiab cadmium. Lawv biocompatibility nyob ze rau kev kho mob - cov qauv qib. US FDA daim ntawv pov thawj qhia tau hais tias tom qab cog, cov ntaub so ntswg tsis kam ntawm titanium alloy thav duab yog tsawg dua 0.1%, deb tshaj li 5% ntawm cov nickel alloys. Rau cov neeg uas muaj tawv nqaij rhiab heev, titanium alloy thav duab tsis yog tsuas yog ib qho kev xaiv zoo xwb tab sis kuj yog ib qho kev lees paub ntawm kev noj qab haus huv thiab kev nyab xeeb.
Craftsmanship thiab Tsim: Kev Hloov ntawm "Bulky" mus rau "Exquisite"
Qhov nyuaj ntawm kev ua cov titanium alloys ib zaug yog ib qho teeb meem rau lawv txoj kev siv dav dav -lawv lub zog siab xav tau cov cuab yeej siv hnyav- lub luag haujlwm stamping, thiab lawv cov qauv ntxeem tau yuav tsum tau vuam hauv qhov chaw nqus. Txawm li cas los xij, nrog kev nce qib thev naus laus zis, niaj hnub titanium alloy thav duab tuaj yeem ua tiav ultra- nyias tsim: lub tuam tsev tuab tuaj yeem tswj tau li ntawm 1.2 hli, 30% nyias dua li cov hlau zoo tib yam; thav duab kab yog smoother, tso cai rau cov creation ntawm rimless thiab semi-rimless styles. Lub hom phiaj siab - kawg, los ntawm 3D tshuab luam ntawv, tau txo qhov hnyav ntawm titanium alloy thav duab ntxiv mus rau 10 grams thaum tuav cov qauv kev ruaj ntseg, ua tiav qhov sib npaug ntawm "lub teeb thiab zam."
Los ntawm nws lub teeb yuag tsim uas txo lub nra ntawm tus choj ntawm lub qhov ntswg mus rau nws cov corrosion kuj tiv thaiv hws; los ntawm nws cov kev cuam tshuam -cov qauv tiv taus thiab muaj zog rau nws cov biocompatibility uas maj mam tiv thaiv cov tawv nqaij rhiab, txhua qhov zoo ntawm titanium alloy eyeglass thav duab stems los ntawm kev tawg ntawm cov ntaub ntawv kev tshawb fawb thiab kev nce qib hauv kev tsim tshuab. Nws tsis yog tsuas yog kev txhim kho hauv cov khoom siv tsom iav xwb, tab sis muaj kev txhawj xeeb heev rau tus neeg hnav kev noj qab haus huv thiab kev nplij siab. Kev xaiv cov titanium alloy tsis yog xaiv ib lub tsom iav xwb, tab sis xaiv qhov sib dua, ruaj dua, thiab noj qab nyob zoo.
