1.Nws puas tsim nyog ua raws li cov qauv kev kho mob?
Cov qib feem ntau: Cov ntsiab lus tseem ceeb tshaj plaws yog AISI 316L lossis ASTM F138 tus qauv kho mob- qib stainless hlau (ie, 316L-V). Ntawm no, "L" sawv cev rau cov pa roj carbon tsawg, txo qis carbide nag lossis daus thiab yog li txhim kho corrosion kuj; "V" sawv cev rau lub tshuab nqus tsev melting, kom ntseeg tau tias siab purity heev.
Qhov sib txawv ntawm 316L zoo tib yam: Txawm hais tias cov tshuaj muaj pes tsawg leeg zoo sib xws, kev kho mob - qib stainless hlau muaj qhov yuav tsum tau nruj heev ntxiv txog biocompatibility (tsis yog- lom, tsis yog- tsis haum, tsis yog- carcinogenic), hlau ion nag lossis daus, tsis yog - hlau suav nrog, thiab grain loj. Ordinary industrial 316L txias-rolled coils tsis tuaj yeem hloov ncaj qha.
2.Dab tsi yog qhov yuav tsum tau ua rau cov txheej txheem txias dov?
Purity thiab Uniformity: Tag nrho cov txheej txheem, los ntawm smelting thiab kub dov mus rau txias dov, yuav tsum tau nqa tawm nyob rau hauv ib tug heev huv cheeb tsam kom tsis txhob muaj kab mob. Lub microstructure yuav tsum zoo ib yam thiab tsis xws luag -dawb.
Surface Quality: Tsis tshua muaj roughness (smoothness) yog yuav tsum tau, dawb los ntawm khawb, yob cov cim, oxidation, thiab lwm yam defects, raws li nws yuav siv ncaj qha rau precision machining los yog tuaj rau hauv kev sib cuag nrog tib neeg cov ntaub so ntswg.
Stable Mechanical Properties: Yield zog, hardness, elongation, thiab lwm yam kev ntsuas yuav tsum tsis tsuas yog ua tau raws li cov qauv, tab sis lub stability ntawm tag nrho cov yob yuav tsum tau zoo heev los xyuas kom meej kev ua tau zoo nyob rau hauv ntau txhiab ntawm manufactured instruments.
3.Vim li cas txias -rolled coil yog ib qho tsim nyog ntawm cov khoom siv raw?
Rau cov chaw tsim khoom siv kho hniav, nrhiav kev kho mob -qib stainless hlau txias- dov coils (feem ntau yog nyias strips lossis foils) raws li cov khoom siv raw yog ntau heev rau cov hauv qab no:
Tsim nyog rau precision stamping: Ntau qhov kev kho hniav yog qhov me me, cov khoom muaj tseeb tsim los ntawm kev siab -ceev precision stamping. Txias- dov nyias strips yog cov khoom siv zoo tagnrho rau cov txheej txheem stamping.
Ua kom yooj yim rau kev ua haujlwm tom ntej: Lawv tuaj yeem txiav tau yooj yim, xuas nrig ntaus, khoov, thiab laser- txiav.
Tus nqi thiab kev ua haujlwm: Muab piv rau kev yuav khoom ncaj qha los yog cov blocks, siv cov coils tso cai rau cov qib siab ntawm automation hauv kev tsim khoom tas mus li, ua rau muaj kev siv cov khoom siv siab thiab tsim nyog rau kev tsim khoom loj.
4.Dab tsi yog cov kauj ruam tseem ceeb ntawm txias- dov coils mus rau cov cuab yeej kho hniav?
Precision stamping/machining: Siv siab -precision tuag los ua cov cuab yeej ntsuas.
Kev tu thiab degreasing tsis tu ncua: Tshem tawm tag nrho cov roj thiab cov pa paug tawm ntawm kev ua haujlwm.
Kev kho cua sov tseem ceeb (kev kho kev daws teeb meem): Tshem tawm cov kev ntxhov siab sab hauv los ntawm txias dov thiab machining, rov ua kom cov khoom zoo dua corrosion thiab toughness.
Nto finishing:
Electropolishing: Qhov no yog cov kauj ruam tseem ceeb. Microscopic protrusions ntawm qhov chaw raug tshem tawm siv cov txheej txheem electrochemical, uas ua rau ib qho tsis tshua muaj neeg du, ci, thiab passivated nto. Ib tug du nto txo cov plaque adhesion, thaum lub passivation zaj duab xis (chromium- nplua nuj oxide txheej) zoo heev txhim kho corrosion kuj.
Lwm yam kev kho mob: Nyob ntawm qhov yuav tsum tau ua, sandblasting, kub plating (rau kev txhim kho kom zoo nkauj lossis tiv thaiv kev ua xua npib tsib xee hauv qee tus neeg mob), thiab lwm yam, kuj tuaj yeem ua.
Kev tu kom huv thiab ua kom tsis muaj menyuam: Ua kom cov khoom kawg yog tsis muaj menyuam thiab pyrogen -dawb.
Kev tshuaj xyuas kom zoo: suav nrog qhov ntev, qhov chaw tiav, tshuaj lom neeg muaj pes tsawg leeg, cov khoom siv kho tshuab, thiab qhov tseem ceeb tshaj plaws, kev sim biocompatibility (xws li cytotoxicity, rhiab heev, thiab kuaj kev khaus).
5.Cov lus qhia tseem ceeb yog dab tsi?
Yog tias koj yog cov chaw tsim khoom nrhiav cov ntaub ntawv: Koj yuav tsum nrhiav cov chaw tsim khoom tshwj xeeb steel nrog cov ntawv pov thawj khoom siv kho mob (xws li Sandvik (Sweden), ThyssenKrupp (Lub Tebchaws Yelemees), Nippon Yakin & Co., thiab Baowu Tshwj Xeeb Steel, tag nrho cov khoom siv kho mob). Thaum yuav khoom, koj yuav tsum thov kom meej meej cov ntaub ntawv uas ua tau raws li cov qauv kev kho mob xws li ASTM F138, ISO 5832-1, lossis GB 4234, thiab tau txais daim ntawv pov thawj cov ntaub ntawv tiav thiab cov ntaub ntawv taug qab.
Yog tias koj yog ib tus kws tshaj lij kev ntsuas cov khoom tsim nyog: Kev lag luam -qib txias- dov coils yuav tsum tsis txhob siv rau hauv cov khoom siv kho mob. Koj yuav tsum pib nrog cov khoom siv kho mob raws li cov khoom siv kho mob thiab ua raws li kev tswj hwm cov cuab yeej kho mob kom zoo (xws li ISO 13485) kom kawg - mus rau - kev tswj xyuas kawg.
Yog tias koj xav paub lossis kawm: Koj tuaj yeem nkag siab txog cov thev naus laus zis thev naus laus zis xws li "kev kho mob- cov qauv qib" thiab "kev kho mob biocompatible," nrog rau qhov txias dov tsuas yog ua cov txheej txheem tsim cov khoom siv raw li xav tau.
