Kev xav tau rau cov pores nyob rau hauv porous titanium daim hlau
Hauv kev siv thev naus laus zis niaj hnub thiab kev lag luam, titanium daim hlau ntxeem tau tau nyiam ntau yam vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb. Raws li kev ua haujlwm siab pom thiab cov khoom sib cais, cov titanium porous daim hlau tsis tsuas yog muaj kev tiv thaiv corrosion zoo heev, kub tsis kam, thiab lub zog txhua yam, tab sis kuj ua rau pom kev ua haujlwm zoo thiab kev sib cais vim lawv cov qauv ntxeem tau. Txawm li cas los xij, kev ua tau zoo ntawm titanium daim hlau ntxeem tau tsis yog nyob ntawm lawv cov khoom siv xwb, tab sis kuj nyob ntawm tus qauv tsim thiab cov kev xav tau ntawm lub qhov hws.
1. Pore loj
1) Uniformity: Qhov pore loj ntawm porous titanium daim hlau yuav tsum tau muab sib npaug sib npaug los xyuas kom pom kev sib cais los yog kev sib cais. Yog hais tias qhov pore loj faib tsis sib npaug, nws yuav ua rau cov nyhuv tsis ruaj khov thiab cuam tshuam rau kev sib cais.
2) Qhov ntau thiab tsawg: Qhov loj ntawm qhov aperture tuaj yeem hloov kho raws li cov ntawv thov tshwj xeeb. Piv txwv li, nyob rau hauv kev lag luam kws tshuaj, cov pore me me feem ntau yuav tsum tau los xyuas kom meej cov purity ntawm cov tshuaj; Hauv kev lag luam kho dej, qhov pore loj dua tuaj yeem tsim nyog rau kev txhim kho kev pom ceev. Feem ntau hais lus, qhov pom tseeb ntawm porous titanium daim hlau tuaj yeem hloov kho ntawm 0.5 ~ 50 μ m.
2. Qhov zoo li
1) Stability: Lub qhov zoo yuav tsum tau ruaj khov kom tsis txhob deformation los yog vau thaum siv. Qhov no pab ua kom pom kev ua tau zoo thiab ruaj khov ntawm cov titanium porous phaj thaum siv mus ntev.
2) Kev xaiv cov duab: Lub qhov pore zoo ntawm cov porous titanium daim hlau tuaj yeem ua tau ncig, elliptical, lossis lwm yam duab geometric, nyob ntawm txoj kev tsim khoom thiab kev thov. Cov duab sib txawv ntawm qhov pore tuaj yeem muaj qhov sib txawv ntawm kev pom kev ua haujlwm, ua kua dej, thiab kev sib cais.
3. Porosity
1) Kev xaiv Scope: Porosity yog hais txog qhov feem pua ntawm cov pore ntim hauv cov porous titanium phaj rau tag nrho cov ntim. Qhov porosity feem ntau yog nyob nruab nrab ntawm 20% thiab 40%, tab sis nws kuj tuaj yeem hloov kho raws li cov kev xav tau tshwj xeeb. Ib qho porosity ntau dua yuav pab txo qhov pom kev ua haujlwm thiab txhim kho permeability efficiency. Txawm li cas los xij, qhov porosity siab dhau heev tuaj yeem txo cov neeg kho tshuab lub zog thiab hnav tsis kam ntawm cov khoom.
2) Kev cuam tshuam kev ua tau zoo: Porosity muaj feem cuam tshuam rau biocompatibility, bioactivity, txhua yam muaj zog, thiab hnav tsis kam ntawm porous titanium daim hlau. Piv txwv li, hauv kev kho mob, porosity ntau dua tuaj yeem txhim kho biocompatibility thiab pob txha muaj peev xwm ntawm kev cog qoob loo; Hauv cov ntawv thov kev lag luam, qhov porosity tsim nyog tuaj yeem sib npaug pom kev ua haujlwm zoo thiab lub zog txhua yam.
4. Distribution thiab stability ntawm pores
1) Uniform faib: Cov pores nyob rau hauv lub porous titanium phaj yuav tsum tau sib npaug zos thiab stably faib thoob plaws tag nrho cov phaj saum npoo kom ntseeg tau zoo pom kev ua tau zoo. Yog tias qhov sib faib ntawm qhov tsis sib npaug, nws yuav ua rau lub zog pom hauv zos siab dhau lossis qis dhau, cuam tshuam rau cov nyhuv pom thiab cov khoom ruaj khov.
2) Lub sij hawm ntev stability: Porous titanium daim hlau yuav tsum muaj kev ruaj ntseg thiab cov duab ntawm lub pores tsis hloov thaum siv. Qhov no pab kom muaj kev sib xws hauv kev pom kev ua haujlwm thiab kev ntseeg tau ntev ntawm cov khoom siv.
Cov kev cai rau qhov pores nyob rau hauv porous titanium daim hlau yog multifaceted, xws li pore loj, pore zoo, porosity, raws li zoo raws li pore tis thiab stability. Cov kev cai no sib sau ua ke txiav txim siab qhov kev ua haujlwm pom thiab kev siv ntau yam ntawm porous titanium daim hlau. Thaum tsim thiab siv cov titanium ntxeem tau daim hlau, cov kev xav tau no yuav tsum tau ua kom tiav los xyuas kom meej tias lawv tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb.
