Cov Txheej Txheem Txheej Txheem Txheej Txheem: Kev tsim cov koob txhaj tshuaj Precise yuav tsum muaj cov ntaub ntawv tshawb fawb thiab kev tsim vaj tsev sib piv rau cov hauv Kev Lag Luam Semiconductor.

Core technical barriers: Kev tsim cov koob tshuaj kho mob zoo yuav tsum muaj cov ntaub ntawv tshawb fawb thiab kev tsim vaj tsev zoo piv rau cov hauv kev lag luam semiconductor. Cov txheej txheem tseem ceeb ntawm cov teeb meem yog nyob rau hauv tag nrho cov saw hlau tswj cov khoom, txheej txheem, thiab khoom siv. Cov ntaub ntawv metallurgy yog lub hauv paus ntawm lub hauv paus. Kev kho mob- qib 316L stainless hlau tsis yog cov hlau tsis zoo li qub; nws cov ntsiab lus carbon yuav tsum tau tswj qis dua 0.03%, thiab cov ntsiab lus nitrogen (0.1-0.16%) yuav tsum tau ntxiv los txhim kho lub zog yam tsis muaj kev txo qis biocompatibility. Sab saum toj manufacturers zoo li Terumo muaj lawv tus kheej metallurgical kuaj. Los ntawm ob txheej txheem ntawm lub tshuab nqus tsev induction melting thiab electroslag remelting, lawv tswj tag nrho cov nqi ntawm impurity ntsiab kom qis dua 50 ppm, xyuas kom meej tias cov koob raj tsis tsim microcracks thaum lub sij hawm kos duab. Ntau tshaj yog daim ntawv thov kev nco alloys. Lub sijhawm hloov pauv kub ntawm npib tsib xee{15}}titanium alloy koob yuav tsum tau tswj hwm ntawm Af=28 ± 2℃kom ua tiav cov yam ntxwv ntawm kev nyuaj ntawm chav tsev kub thiab hloov tau yooj yim tom qab nkag mus rau hauv lub cev, uas yuav tsum muaj qhov hloov pauv me me ntawm nickel -titanium atomic piv li ntawm 50.8%. Precise forming technology yog lub hauv paus ntawm kev tsim khoom. Koob raj kos duab zoo li yooj yim, tab sis nws suav nrog kev tsim qauv nrog ntau dua 20 txheej txheem. Tus lej tswj kev kos duab tshuab ntawm Heidemann hauv lub teb chaws Yelemees siv cov txheej txheem pwm pwm, nrog rau txhua tus ntoo khaub lig-sectional txo tus nqi tswj nruj me ntsis ntawm 15-20%, cuam tshuam nrog 12 hydrogen gas tiv thaiv annealing txheej txheem kom tshem tawm kev ua haujlwm nyuaj. Qhov tseem ceeb tshaj plaws txoj kev siv lub tshuab sib tsoo siv peb - nto sib tsoo tshuab, nrog peb lub log sib tsoo ib txhij ntawm cov ces kaum sib txawv (lub ntsiab txiav ntawm 18 degree, sab txiav nto ntawm 10 degree, thiab thim rov qab txiav nto ntawm 6 degree), tsim lub ntse "triacontahedron" qauv, nrog lub zog qis dua li 40% turc. ob- nto sib tsoo. Lub patented "Fish Hook" sab hauv phab ntsa tsim ntawm JMS hauv Nyij Pooj txheej txheem kauv microgrooves ntawm lub koob raj sab hauv phab ntsa kom hloov cov ntshav ntws los ntawm turbulent mus rau laminar, txo qis hemolysis ntawm 60%. Txheej thiab kho saum npoo yog tus yuam sij rau kev sib txawv. Kev kho silicification tsis yog yooj yim txau; Nws yog ua tiav los ntawm cov ntshav plasma- txhim kho cov tshuaj vapor deposition, tsim 50-100 nanometer tuab silicon dioxide txheej ntawm lub koob raj nto, txo cov kev sib txhuam coefficient ntawm 0.6 txog 0.05. Lub patent "PentaCut®" tsib-point sib tsoo koob taub ntawm B. Braun Medical nthuav qhia lub zoo meej pentagonal symmetrical qauv nyob rau hauv ib tug electron microscope, ua ke nrog pob zeb diamond-zoo li cov pa roj carbon txheej, ua kom tiav "unfelt puncturing". Lub tshuab anticoagulant txheej yog txawm ntau ingenious. Heparin molecules yog covalently bonded rau lub koob phab ntsa los ntawm plasma grafting, tswj kev ua si rau ntau tshaj 30 hnub, txo tus nqi ntawm catheter-txog thrombosis los ntawm 15% mus rau 2%. Kev soj ntsuam zoo thev naus laus zis tsim cov kab kev tiv thaiv zaum kawg. 100% kev tshuaj xyuas tag nrho tau dhau los ua tus qauv kev lag luam, tab sis qhov tseeb ntawm kev tshawb pom tau ua tiav tas li. Qhov kev tshuaj xyuas qhov muag pom ntawm Omega hauv Tebchaws Meskas tau ntes cov koob taub qhov tsis xws luag ntawm qhov nrawm ntawm 200 ntas ib ob, nrog rau kev daws teeb meem ntawm 0.5 microns, muaj peev xwm txheeb xyuas qhov pom tsis pom. Lub pneumatic ntsuas ntsuas ntawm Maier nyob rau hauv lub teb chaws Yelemees ntsuas lub puab kab ntawm lub koob raj nrog 0.1 microns ntawm qhov tseeb los ntawm 0.2 MPa compressed cua. Qhov nruj tshaj plaws yog "kev sim ua haujlwm", piv txwv txhua pawg ntawm cov koob txhaj tshuaj rau lub zog ntawm lub zog, tus nqi ntws, thiab kev sib tsoo quab yuam, nrog cov ntaub ntawv xa tawm hauv lub sijhawm rau MES system. Ib qho parameter drift yuav ua rau cov hauv paus ua rau kev txheeb xyuas. Cov kev cuam tshuam kev lag luam no tau tsim lub voj voog 6-8-xyoo R & D thiab ntau lab nyiaj daus las hauv cov cuab yeej siv, ua rau nws nyuaj rau cov neeg tuaj tshiab hla thiab ua kom ntseeg tau tias cov tuam txhab ua lag luam tswj hwm 35-45% cov txiaj ntsig tag nrho.
