Daim ntawv nco Nitinol Qwstseem hu ua nitinol nco alloy pas nrig. Thaum nws los ua lub cim xeeb alloy, ntau tus neeg tau hnov nws lub npe. Txawm hais tias nws yog deformed li cas, nws tuaj yeem hloov pauv mus rau nws qhov qub qub tom qab tau rhuab mus rau qhov kub thiab txias.
Txog tam sim no, kaum ob lub cim xeeb alloys tau pom nyob rau hauv lub ntiaj teb no, ntawm cov nitinol alloy yog qhov ntxov tshaj plaws tsim thiab siv tau zoo tshaj plaws alloy khoom.
Lub cim xeeb nitinol bar yog binary alloy tsim los ntawm nickel thiab titanium. Ntxiv nrog rau nws cov cim cim xeeb muaj nuj nqi, nws kuj muaj cov khoom zoo heev thiab yog cov khoom siv zoo heev.
1) Cov yam ntxwv ntawm lub cim xeeb: Nitinol alloy yog deformed los ntawm sab nraud quab yuam ntawm qhov kub thiab txias, thiab tseem tuaj yeem tswj cov duab deformed tom qab tshem tawm cov quab yuam sab nraud, tab sis nws tuaj yeem rov qab mus rau qhov qub qub ntawm qhov kub siab dua.
2) Hyper elasticity: Lub super elasticity ntawm nitinol alloy tuaj yeem hloov nrog cov kev kho cua sov. Thaum lub nitinol pas nrig yog rhuab saum 400 degree, lub superelasticity pib txo. Peb yog lub cim xeeb nitinol bar.
1. Cov khoom tshwj xeeb
1) Anti-toxicity: Cov tshuaj tshwj xeeb muaj pes tsawg leeg ntawm nickel-titanium zoo nco alloy, uas yog, npib tsib xee-titanium thiab lwm yam atomic alloys, muaj li ntawm 50% npib tsib xee, thiab paub tias muaj carcinogenic thiab mob qog noj ntshav. Feem ntau, titania ACTS ua raws li txheej txheej thaiv ntawm qhov chaw, yog li Ni-TI alloys muaj biocompatibility zoo. TiXOy thiab TixNiOy hauv txheej txheej tuaj yeem cuam tshuam qhov tso tawm Ni.
2) Lub npe hu ua superelasticity yog hais txog qhov tshwm sim uas cov qauv ntawm cov qauv yog ntau dua li cov elastic txwv strain nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, thiab nws yuav cia li rov qab thaum unloading. Nyob rau hauv lwm yam lus, nyob rau hauv lub xeev ntawm cov niam txiv theem, kev nyuaj siab-induced martensitic transformation tshwm sim vim hais tias ntawm cov kev nyuaj siab, yog li cov alloy exhibits mechanical zog sib txawv ntawm cov ntaub ntawv zoo tib yam, nws elastic txwv yog ntau loj dua li cov ntaub ntawv zoo tib yam, thiab muaj. Tsis muaj qhov sib txawv Ua raws Hooke Txoj Cai. Nyob rau hauv sib piv rau lub cim xeeb zog, superelasticity tsis muaj cua sov.
3) Kev ua haujlwm poob siab zoo: qhov ntau dua qhov kev co tshwm sim los ntawm zom thiab sib tsoo cov hniav thaum hmo ntuj, qhov ntau dua qhov kev puas tsuaj rau cov hauv paus hniav thiab cov ntaub so ntswg. Los ntawm kev sib txawv attenuation thwmsim, nws tau pom tias qhov kev vibration amplitude ntawm stainless hlau hlau yog ntau dua li ntawm superelastic npib tsib xee-titanium hlau, thiab qhov pib vibration amplitude ntawm superelastic nickel-titanium hlau tsuas yog ib nrab ntawm cov hlau stainless. hlau, uas muaj kev co zoo thiab kev poob siab absorbing yam ntxwv. Kev tiv thaiv Arc yog qhov tseem ceeb rau kev noj qab haus huv ntawm cov hniav. Ib txwm arcs, xws li stainless hlau xaim, zoo li yuav ua rau kom cov hauv paus nqus nqus.
4) rhiab heev rau qhov kub thiab txias hloov nyob rau hauv lub qhov ncauj kab noj hniav: Orthodontic muaj peev xwm ntawm stainless hlau nyob ntawm tej thiab CoCr alloy orthodontic xov hlau yog yeej tsis cuam tshuam los ntawm qhov ncauj kub. Lub peev xwm orthodontic ntawm cov tawv nqaij elastic heev Nitinol kho hniav nws txawv nrog qhov kub ntawm qhov ncauj. thaum lub deformation yog tas li. Orthodontic muaj peev xwm nce nrog qhov kub thiab txias. Ntawm qhov tod tes, nws ua kom nrawm nrawm ntawm cov hniav, txij li qhov kub hloov pauv hauv lub qhov ncauj kab noj hniav txhawb cov ntshav ntws hauv cov ntshav stasis vim capillary stagnation tshwm sim los ntawm cov khoom siv orthodontic, tso cai rau kho cov hlwb kom tau txais cov as-ham txaus rau lub sijhawm no. Cov hniav txav los tswj lawv qhov tseem ceeb thiab ua haujlwm zoo. Ntawm qhov tod tes, orthodontists tsis tuaj yeem tswj xyuas lossis ntsuas lub peev xwm orthodontic hauv qhov ncauj ib puag ncig.
