Yuav ua li cas tuaj yeem siv tshuab hlau siv los tsim cov precision kua nozzles?

一, cov teeb meem nrog cov teeb meem xws li qub thiab cov khoom tshiab uas hlau luam ntawv qhib li
1. Cov teeb meem nrog kev ua haujlwm ib txwm muaj
Precision kua lub nozzles muaj tus qauv me uas koom nrog micrometer {{qib arrays, thiab multi- txheej cov haujlwm ua haujlwm. Ua kom lawv, cov qauv nruj no yuav tsum tau ua kom tiav:
Siab siab: Lub nozzle qhib yuav tsum nyob nruab nrab ntawm 10 thiab 50 microns, thiab Flow channel nto ra yuav tsum tsawg dua 0.8 μm.
Cov qauv teeb meem yog qhov nyuaj vim tias nws yuav tsum muaj cov khoom ua kua cov khoom siv, cov qhov cuav, thiab thaj tsam qhov chaw txhaj tshuaj ntsuam uas muaj peev xwm ua tau. Tsoos cap machining xav tau ntau cov txheej txheem sib txawv, uas ua rau nws kim thiab muab cov txiaj ntsig tawm tsawg.
Cov Khoom Siv: cov ntaub ntawv uas tiv taus corrosion, muaj cov thermal zoo, lossis yog nickel {}
Piv txwv li, ua cov dav dav hlau hau lub qub {{0} Fashion Way entroles thiab ces txheej txheem hlau chaw nres nkoj los ua qhov chaw. Tab sis qhov tsis sib xws ntws tawm ntawm lub teeb ua rau ntawm ciam teb ntawm cov kua zaub mov ua kom txaus, uas nyeg cuam tshuam nrog lub qhov ntswg ntawm lub whazzzle thiab ua rau lub dav hlau tsis zoo.
2. Cov txiaj ntsig tseem ceeb ntawm cov hlau 3D luam
Hlau tshuab luam ntawv tsim peb {- cov khoom siv hlau ncaj qha los ntawm melting lossis txau cov ntaub ntawv hlau rau sab saum toj ntawm ib leeg, uas mus dhau ntawm txoj kev siv lub cev ntawm cov hau kev uas twb muaj lawm.
Kev ywj pheej tsim qauv: nws yuav ua rau muaj cov khoom siv txaus, lossis tsim qauv ua ke, nyiam qhov chaw nres nkoj ua kua, qhov cuav rau hauv ib qho.
LPBF thev naus laus zis yuav ua tiav qhov tseeb ntawm ± 0.05mm. Thaum paired nrog tshaj tawm {{2} Kev ua cov txheej txheem tshuaj lom neeg xws li cov tshuaj sib tsoo ntawm cov tshuaj polishing thiab sib npaug ntawm 0.4 μ m.
Tus nqi ntawm kev siv cov ntaub ntawv: inkjet hlau 3D luam ntawv siv rau ntawm-}}}}}} Cov hmoov txaj zoo tshaj li ntawm 50% uas cov hmoov hmoov zoo nkauj siv.
Quick I6 {- {{-}} Qhov ua piv txwv me me thiab kho cov khoom me me rau txhua tus neeg siv khoom.
2, tseem ceeb siv cov tshuab luam ntawv hlau hauv kev ua kom tsis muaj cua
1. Nozzle rau microfluidic nti
Microfluidic chips yuav tsum tau muaj ntws raws, li qub, thiab cov tshuaj yej cov tshuaj uas tsuas yog qee qhov micrometres dav. Cov txheej txheem mos mos ua rau nws nyuaj ua cov hlau seem nrog cov ntsuas hluav taws xob ntau. Cov txheej txheem LPBF tuaj yeem luam tawm stainless hlau lossis titanium alloy substrates, siv tshuaj lom etching ua kom microchhannels ua rau cov inkjetHlau 3D PrintingTxhawm rau ntxiv cov khoom siv ua haujlwm zoo li hydrophobic txheej. Qhov no ua rau cov ntaub ntawv tiv taus corrosion thiab nyab xeeb rau cov muaj sia. Piv txwv li, ib lub tuam txhab tsim cov check kuaj mob? Tom qab ntawd, nws cov tshuaj tsuag kub nanoparticles mus rau hauv lub hauv paus los ua cov kev txhais cov hluav taws xob, uas ua rau nws peb zaug rhiab dua li cov txheej txheem qub.
2. Inkjet Printing hau rau cov lag luam
Kev sib xyaw ua ke txhiab tus micrometer {{0} {} qhov loj me ntawm cov qauv zoo li polysilicon etching thiab tsevneeg. Inkjet hlau 3D tshuab luam ntawv tshuab tuaj yeem ua cov hauv qab no:
Multi -}}}}} Cov Khoom Siv Hluav Taws Xob (rau cov qauv kev sib koom ua ke) thiab cov khoom siv tsav tsheb) nyob rau tib lub sijhawm los ua kom tiav cov khoom siv tau ua haujlwm;
Txhim kho lub nozzle array: los ntawm kev txhim kho cov qauv, asymmetric ntws chanels yog ua rau qis dua ink droplet splaning thiab nce kev daws teeb meem rau 2400dPI.
Kev kho siab sai: kom nrawm rau kev txhim kho kev voj voog, hloov lub nozzle aperture thiab channel ntsuas thiab cov khoom siv viscosity thiab nro.
3. Nozzle rau 3D Luam Ntawv
Metal 3D printing nozzles have to be able to handle high temperatures (>2000 °C) and high pressures (>100MPA). Cov txheej txheem ib txwm muab tso ua ke, zoo li brazing lossis electron nqaj vuam, tuaj yeem yooj yim ua rau cov kev ntxhov siab thermal. Ded Technology, xws li coaxial hmoov pub laser cladding, tuaj yeem ua cov hauv qab no:
Kev sib xyaw ua ke: qhov chaw nockel - based alloy nozzles ncaj qha rau ntawm cov teeb meem kev ua yeeb yam;
Kev tsim ua haujlwm Gradient: Lub nozzle tso tawm tau tsim ntawm tooj liab alloy nrog muaj zog ntawm titanium alloy nrog lub zog siab. Qhov nyiaj txiag tswj hwm no thiab lub zog tswjfwm.
Kho thiab Remanufacturing: Hnav cov tsis tau kho siv cov qauv laser hauv zos, uas ua rau lawv kav ntev dua peb zaug ntev.
3, Teeb meem thiab cov kev daws teeb meem hauv thev naus laus zis
1. Tswj ntawm qhov chaw sib tw
Qhov ntxhib ntawm saum npoo ntawm cov khoom hlau luam tawm feem ntau yog ra ntau dua lossis sib npaug ntawm 6.3 μm, uas yuav tsum tau txhim kho los ntawm post- kev ua:
Tshuaj lom neeg polishing, uas siv cov acid ntxuav kom tshem tau cov pob ntawm saum npoo av, tuaj yeem qis ra kom tsawg dua 3.2 μm. Laser micro cladding, ntawm qhov tod tes, ua kom tuab oxide txheej rau saum npoo thaum ua nws tsawg dua.
Hybrid Raug: Siv ob qho tib si 3D luam ntawv thiab CNC Precision Machining kom tau txais qhov tseem ceeb saum npoo RA ntawm tsawg dua 0.8 μ} Nrhiav cov tsis xws luag
Muaj cov teeb meem nrog cov hmoov txaj melting yaj, xws li pores thiab cov kab nrib pleb, yog vim li ntawd nws yuav tsum tau sim nws kom nws ua haujlwm.
Muaj Kev Lag Luam CT: nrhiav cov qhov sab hauv kom paub tseeb tias qhov ntom ntom yog tsawg kawg 99.5%;
Ntsuam xyuas kev qaug zog: kom paub tseeb tias cov kev pabcuam lub neej ua kom muaj kev pabcuam tshwj xeeb, ua 10 mus txog 10 los ntawm kev thauj khoom raws li ASTM E466 tus qauv.
2. Sib tsam nrog ntau tshaj ib cov khoom siv
Inkjet hlau 3D luam ntawv yuav tsum tau nrog qhov tseeb tias cov hlau sib txawv tau sib txawv cov ntsiab lus thiab cov teeb meem nrog kev sib raug zoo ntawm lub interface:
Nanoparticle Ink: Ua mem tes nrog lub siab me me me me taw tes alloy, xws li bi-}}}}}}}, los luam tawm ntawm cov kub qis.
Laser rov qab los yog ultrasonic vuam tuaj yeem ua qhov txuas ntawm cov khoom sib txawv.
