Lub neej ntev npaum li cas ntawm cov khoom titanium?
Nyob rau niaj hnub no nrhiav kev zoo siab - lub neej zoo, durability thiab kev nyab xeeb tau dhau los ua qhov tseem ceeb rau cov neeg siv khoom thaum xaiv cov khoom siv niaj hnub. Titanium, cov khoom siv tsis tshua muaj hu ua "qhov chaw hlau" thiab "biometal," tab tom nce los ntawm kev lag luam siab -kawg mus rau cov tsev neeg niaj hnub, dhau los ua qhov kev xaiv zoo tshaj plaws rau kev noj qab haus huv, ua tsaug rau nws lub neej ntev thiab kev noj qab haus huv zoo dua.
Titanium's durability stems los ntawm nws lub cev tshwj xeeb. Nws cov kev tiv thaiv corrosion yog ntau tshaj 15 npaug ntawm cov hlau tsis zoo tib yam, thiab nws tseem ruaj khov txawm tias nyob rau hauv qhov chaw huab cua xws li acids, alkalis, thiab ntsev tsuag. Cov yam ntxwv no tau raug lees paub tag nrho hauv kev kho mob- cov ntaub ntawv titanium alloy cranioplasty tuaj yeem nyob tau ntau dua 20 xyoo thiab muaj biocompatible nrog tib neeg cov ntaub so ntswg, nrog zoo tsis muaj kev cuam tshuam. Hauv chav ua noj, titanium pots siv 10, 000+ plasma cladding thev naus laus zis los tsim cov qauv nanoscale honeycomb microporous, ua ke nrog 10- teev 360℃nitriding kev kho mob, ua rau muaj kev tiv thaiv corrosion ntau tshaj li ntawm cov tsoos hlau pots. Txawm tias thaum simmering muaj zog acidic cov khoom xyaw xws li ntev-simmered soups thiab tsoos suav tshuaj rau ncua sij hawm, nws yuav tsis xeb los yog leach hlau. Qhov kev ua tau zoo no tseem muaj pov thawj hauv cov khob dej titanium, uas feem ntau kav ntev dua 5 xyoos, thiab nrog kev saib xyuas kom zoo, txawm tias mus txog 10 xyoo, deb tshaj li lub neej ntawm cov khoom tawg yooj yim xws li iav thiab ceramics.
Titanium lub neej ntev yog ntxiv txhim kho los ntawm nws cov hnav tsis kam. Titanium lub zog zoo ib yam li hlau, tab sis nws qhov hnyav tsuas yog 60% ntawm cov hlau. Qhov "lub teeb thiab muaj zog" tus yam ntxwv no ua rau nws yog ib qho khoom siv zoo tagnrho rau cov tais diav thiab cov khoom siv zoo nkauj. Piv txwv li, titanium chopsticks tuaj yeem kav ntev dua 5 xyoos, piv rau 3-6 hli hloov lub voj voog ntawm xyoob thiab ntoo chopsticks. Qhov no tsis tsuas yog txo cov peev txheej pov tseg xwb tab sis kuj zam kev pheej hmoo ntawm cov kab mob carcinogens xws li aflatoxin thiab Helicobacter pylori loj hlob nyob rau hauv qhov grooves ntawm chopsticks 'deg. Titanium's hnav tsis kam kuj tseem muaj pov thawj nyob rau hauv aerospace teb-titanium alloy qhov chaw tswj kev ruaj ntseg txawm nyob rau hauv high-ceev kev sib txhuam ib puag ncig. Cov yam ntxwv no, hloov mus rau cov khoom siv niaj hnub, txhais tau hais tias titanium khob thiab pots tuaj yeem nyob zoo li tshiab txawm tias tom qab siv thiab tu.
Titanium's "kev noj qab haus huv lifespan" kuj yog sib cais los ntawm nws cov biocompatibility. Raws li cov hlau tsuas yog tsis yog - lom rau tib neeg lub cev, titanium yog dav siv hauv kev cog qoob loo xws li lub plawv stents thiab cov pob qij txha. Nws ib txwm ua oxide zaj duab xis tiv thaiv kev tso tawm ntawm cov hlau ions, kom ntseeg tau tias txawm tias kev sib cuag nrog cov zaub mov los yog tib neeg cov ntaub so ntswg ntev yuav tsis ua rau muaj kev tsis haum lossis lom. Cov cuab yeej no tseem ceeb tshwj xeeb hauv cov khoom siv hauv chav ua noj: cov lauj kaub titanium tuaj yeem ua rau cov khoom noj muaj kua qaub, titanium khob tuaj yeem tuav kas fes, kua txiv hmab txiv ntoo, thiab lwm yam dej haus, thiab titanium tableware tsis tso cov tshuaj phem xws li bisphenol A (BPA) ntawm qhov kub zoo li cov khoom yas. Tsis tas li ntawd, titanium ions muaj cov tshuaj tua kab mob ntuj. Kev sim qhia tau hais tias khaws cia cov khoom seem hauv cov thawv titanium txuas ntxiv lawv lub neej txee los ntawm 2-3 zaug piv rau cov thawv ntim khoom noj zoo tib yam. Cov yam ntxwv no qhia tau hais tias muaj peev xwm zoo hauv thaj chaw xws li cov khoom me me thiab cov khoom siv sab nraum zoov.
Txawm li cas los xij, "kev ua neej ntev" ntawm cov khoom titanium tsis yog qhov tseeb; lawv lub neej muaj kev cuam tshuam loj heev los ntawm kev siv tus cwj pwm thiab kev saib xyuas. Piv txwv li, titanium pots yuav tsum tsis txhob qhuav -rhaub los yog raug hloov kub sai sai, titanium khob yuav tsum tau tiv thaiv los ntawm tej yam khoom nyuaj, thiab titanium hniav nyiaj hniav kub yuav tsum tau ntxuav tsis tu ncua los tiv thaiv corrosion los ntawm hws. Txawm li cas los xij, nws lub neej tag nrho nyob deb tshaj li ntawm cov khoom zoo sib xws- titanium eyeglass thav duab tseem zoo li lub teeb tshiab tom qab 10 xyoo ntawm kev siv, titanium watches tseem khaws lub sijhawm kom raug tom qab tau nkag mus rau hauv dej hiav txwv, thiab titanium sab nraum zoov fwj dej khaws cia lawv cov ntsaws ruaj ruaj zoo tom qab raug muab tso tseg. Qhov kev lees paub thib ob ntawm "durability" thiab "kev noj qab haus huv" ua rau cov khoom titanium yog thawj qhov kev xaiv rau cov neeg siv khoom nrhiav ntev -lub sij hawm tus nqi.
Los ntawm kev cog qoob loo rau cov khoom siv hauv chav ua noj, los ntawm qib siab - cov hniav nyiaj hniav kub mus rau sab nraum zoov iav, titanium tau hloov kho cov neeg siv khoom xav nrog nws ob qhov zoo ntawm "ntev" thiab "kev noj qab haus huv." Nws tsis yog tsuas yog cov khoom siv tshiab xwb tab sis kuj sawv cev rau "kev ua neej nyob ruaj khov thiab noj qab nyob zoo" lub tswv yim ntawm kev noj qab haus huv- txo cov peev txheej siv nrog cov cuab yeej siv tau ntev dua thiab tiv thaiv tsev neeg noj qab haus huv nrog cov ntaub ntawv zoo dua. Nrog rau qhov nrov ntawm titanium ua technology, titanium cov khoom tau nkag mus rau ntau txhiab tsev neeg ntawm tus nqi pheej yig dua, dhau los ua "cov neeg saib xyuas kev noj qab haus huv tsis pom" rau cov tsev neeg niaj hnub los txhim kho lawv lub neej zoo. Nyob rau hauv lub neej yav tom ntej, daim ntawv thov scenarios ntawm titanium yuav nthuav dav ntxiv, txhaj tshuaj ntau zog rau kev noj qab nyob zoo.
