Cov chaw tsim khoom cog lus muab ib pawg ntawm SLM titanium cov lus qhia kev phais. Lawv saib zoo meej thiab ua tau raws li qhov tshwj xeeb. Txawm li cas los xij, ib qho khoom pov thawj pom pom cov hmoov seem seem thiab cov kua siv ua haujlwm tseem nyob hauv cov kab sab hauv. Cov tshuaj tsis yog reprinting - nws yog ib tug validated ultrasonic tu voj voog.
Ultrasonic tu yog ib qho zoo tshaj plaws thiab dav siv txoj hauv kev kom tshem tawm cov kab mob ntawm cov hlau 3D luam ntawv kho mob. Nws ua tau zoo thaum mus txog qhov nyuaj geometries qhov twg cov txheej txheem ib txwm ua tsis tau, tab sis tsuas yog thaum cov txheej txheem raug kho kom raug rau cov khoom siv, tsim qauv, thiab siv tau.
Vim li cas Kev Kho Mob 3D Printing Parts xav tau kev tu tshwj xeeb
Hlau 3D luam ntawvtsim kom muaj kev sib tw sib kis. Cov txheej txheem -los ntawm- txheej txheem SLM tawm cov hmoov tsis muaj hmoov, tshwj xeeb tshaj yog nyob rau hauv cov qauv lattice thiab cov kab sab hauv. Tshaj tawm- cov kauj ruam ua haujlwm xws li machining lossis hlaws blasting tuaj yeem qhia cov khib nyiab ntxiv.
Kev tu tus qauv kev lag luam feem ntau poob qis rau kev kho mob- qib yuav tsum tau ua vim nws tsis ua tiav qib kev huv uas tsim nyog rau biocompatibility. Cov duab geometries nyuaj - xws li cov qauv ntxeem tau thiab cov cua txias raws li - cov khoom ntxiab uas qhov muag pom tsis pom.
Ti-6Al-4V txha caj qaum nrog ib qho kev sib cuam tshuam cov qauv ntxeem tau muaj hmoov daig 8 hli tob. Qhov no tsis pom sab nraud tab sis ua rau muaj kev pheej hmoo loj ntawm kev tso tawm hauv lub cev. Tshwj xeeb SLM ib feem tu yuav tsum tau.
Yuav Ua Li Cas Ultrasonic Cleaning Ua Haujlwm - Tsis muaj Jargon Version
Ultrasonic tu siv siab - zaus suab nthwv dej dhau los ntawm cov dej da dej. Cov nthwv dej no tsim ntau lab tus kab mob microscopic cavitation npuas uas tsim, loj hlob, thiab tom qab ntawd implode hnyav. Cov implosions tsim cov tshuaj txhuam hniav hauv zos uas tshem tawm cov kab mob los ntawm qhov chaw thiab qhov chaw.
Txoj kev no mus txog qhov twg txhuam thiab siab - cov tshuaj txau tsis tuaj yeem, ua rau nws zoo tagnrho rau cov hlau 3D luam tawm geometries.

Ultrasonic tu puas tuaj yeem ua rau cov hlau 3D luam tawm?
Nws tuaj yeem yog tias tsis muaj (tshwj xeeb tshaj yog zaus, lub zog, lossis chemistry) tsis raug. Kev ua kom zoo tshaj plaws muaj kev nyab xeeb rau titanium, stainless hlau, thiab CoCr.
Ntev npaum li cas ultrasonic tu siv rau cov hlau kho mob?
Feem ntau 5-20 feeb rau ib lub voj voog, feem ntau nrog ntau cov dej yaug.
Dab tsi zaus kuv yuav tsum siv rau ultrasonic tu titanium 3D luam qhov chaw?
40-80 kHz yog qhov ntau tshaj plaws rau Ti-6Al-4V ultrasonic tu.
Puas yog ultrasonic tu txaus rau implantable hlau 3D luam ntawv?
Tsis yog - nws yog ib kauj ruam tseem ceeb tab sis yuav tsum yog ib feem ntawm cov saw hlau uas siv tau tag nrho suav nrog kev ua kom tsis muaj menyuam thiab ua kom tsis muaj menyuam.
Yuav ua li cas kuv validate ib tug ultrasonic tu txheej txheem rau kev kho mob?
Siv qhov phem tshaj -cov ntaub ntawv, ntsuas TOC/particle/endotoxin qib, thiab cov ntaub ntawv rov tsim dua tshiab.
Dab tsi yog qhov txawv ntawm kev ntxuav thiab ua kom tsis muaj menyuam rau cov hlau 3D luam tawm?
Ntxuav tshem tawm cov kab mob; sterilization tua cov kab mob. Ob qho tib si feem ntau xav tau rau kev cog qoob loo.
