Hauv kev ua haujlwm siab -kawg kev lag luam pom, tus nqi ntws thiab qhov siab poob ib txwm yog qhov tsis sib xws.Tseem niaj hnub lim cov ntsiab lus feem ntau yuav tsum lees txais cov nqi qis qis thiab nce siab poob raws li tus nqi ntawm kev ua raws li kev pom zoo. Txawm li cas los xij, qhov tshwm sim ntawm titanium hlau hmoov sintered lim cov ntsiab lus, tshwj xeeb tshaj yog siab porosity titanium lim ntsiab, yog revolutionizing qhov nyiaj tshuav no los ntawm cov txheej txheem kev tawg, ua rau lawv cov khoom tseem ceeb hauv kev pom zoo rau kev lag luam xws li tshuaj, tshuaj, thiab semiconductors. Kab lus no delves rau hauv cov txheej txheem tseem ceeb tom qab cov thev naus laus zis no thiab ua li cas lawv ua tiav qhov kev ua tau zoo tshwj xeeb ntawm ultra- tus nqi ntws siab thiab qis qis.
1. High Porosity: Tsis tsuas yog "Los thiab Porous"
Cov porosity siab yog lub hauv paus ntawm lub cev rau kev ua tiav ultra- tus nqi ntws siab thiab qis qis. Tab sis "siab porosity" ntawm titanium lim caij yog deb ntawm cov khoom yooj yim looseness; nws yog ib qho kev tswj xyuas zoo peb - qhov sib txuas sib txuas hauv lub network.
- Kev txhais thiab qhov tseem ceeb: Porosity yog hais txog qhov feem pua ntawm cov khoom lim cov khoom ntim uas nyob ntawm qhov pores. Rau titanium sintered lim cov ntsiab lus, cov txheej txheem hmoov metallurgy qib siab tuaj yeem ruaj khov nce porosity mus rau 35% -50%, lossis ntau dua. Qhov no txhais tau hais tias mus txog ib nrab ntawm lub ntim muaj cov kua dej raws, hauv paus ua kom tsis tshua muaj siab poob thiab muaj peev xwm txaus.
- Lub Core Contradiction: Nyob rau hauv cov txheej txheem ib txwm muaj, nce porosity feem ntau ua rau kom dav qhov pore loj faib, txo cov qauv lub zog, thiab tsis pom qhov tseeb. Qhov tseeb txheej txheem kev tawg yog nyob rau hauv kev ua tiav siab porosity thaum tib lub sijhawm kom ntseeg tau tias qhov pore loj, txaus cov txheej txheem rigidity, thiab uncompromised pom precision.
2. Kev nthuav tawm Peb Cov Txheej Txheem Ua Haujlwm Zoo
2.1. Precise Spherical Titanium Hmoov thiab Qib Technology
- Hmoov Morphology: High-purity, siab kheej kheej titanium lossis titanium alloy hmoov (xws li Ti6Al4V) yog siv. Spherical hmoov muaj cov dej ntws zoo heev, tsim cov pores tsis tu ncua thiab ruaj khov thaum lub sijhawm ntim khoom. Piv rau cov hmoov tsis sib xws, nws tsim smoother ntws raws ntawm tib theem porosity.
- Particle Size Grading: Nov yog tus ntsuj plig ntawm txoj kev. Los ntawm kev suav thiab kev sim, cov hmoov sib txawv ntawm qhov ntau thiab tsawg (piv txwv li, hmoov coarse ua lub cev pob txha rau siab ndlwg, nruab nrab / zoo hmoov filling qhov khoob kom tswj tau qhov tseeb) yog sib xyaw hauv qhov kev pom zoo. This "grading" allows powder particles to achieve the densest possible packing during pressing and sintering, while forming a highly interconnected pore network with a concentrated size distribution. Qhov no yog tus yuam sij kom ua tiav ob qho tib si siab porosity thiab siab precision.
2.2. Advanced Forming thiab Multi-Theem Gradient Sintering txheej txheem
- Isostatic nias: Txias Isostatic Pressing thev naus laus zis yog ua haujlwm, siv lub zog siab rau cov hmoov los ntawm txhua qhov kev qhia. This results in a green body with uniform density and consistent internal pore distribution, avoiding the density gradients common in traditional uniaxial pressing and laying a homogeneous foundation for sintering.
- Multi-Stage Gradient Sintering: Sintering yog ua nyob rau hauv ib tug siab -kub rauv nyob rau hauv lub tshuab nqus tsev los yog inert cua, raws li ib tug precisely tswj kub profile.
- Tsawg-Temperature Debinding Stage: Cov cua sov qeeb kom huv si tshem tawm cov roj nplua nyeem thiab cov roj adsorbed, tiv thaiv kev tsim kho.
Nruab nrab-Tub Kub Ua Ntej-sintering Theem: Cov hmoov hmoov pib tsim cov ntawv cog lus thawj zaug (caj dab loj hlob), tsim kom muaj zog ua ntej
thaum ua kom lub pore qauv qhib.
- Siab -Tsub Sintering thiab Dwell Time Control: Lub ncov kub thiab lub sij hawm nyob twj ywm yog precisely tswj. Qhov no yog "lub sijhawm tseem ceeb" ntawm tus txheej txheem. Qhov kub thiab lub sij hawm yog txaus los tsim muaj zog metallurgical bonds ntawm cov khoom, kom lub ntsiab lub zog thiab rigidity, tab sis lawv tau ua tib zoo calibrated los tiv thaiv ntau shrinkage los yog kaw lub pores. Qhov kev tswj no kawg xauv rau hauv preset siab porosity thiab phiaj pore loj.
2.3. Pore Structure thiab Surface Post-Kev kho kom zoo
- Pore Kev sib txuas: Cov txheej txheem zoo tshaj plaws kom ntseeg tau tias muaj kev sib tshuam porosity siab heev, lub ntsiab lus feem ntau ntawm qhov pores yog interconnected "zoo pores" es tsis yog kaw "tuag-kawg pores." Qhov no ncaj qha txiav txim siab qhov chaw pom zoo thiab tus nqi ntws.
- Nto Smoothing kho: Tshwj xeeb electrolytic los yog tshuaj polishing yog siv rau sab hauv thiab sab nraud ntws raws ntawm sintered caij. Cov kauj ruam no ua rau txo cov kua dej tsis zoo, txo qis kev poob siab, nrog rau cov txiaj ntsig tshwj xeeb rau cov kua dej viscosity siab.
3. Kev Ua Tau Zoo: Cia cov ntaub ntawv hais lus
Qhov kev ua tau zoo ntawm qhov siab porosity titanium lim ntsiab tsim nrog cov txheej txheem saum toj no yog qhov tseeb:
- Nce tus nqi ntws: Nyob rau tib qhov precision thiab sab nraud qhov ntev, lawv lub peev xwm ntws tuaj yeem yog 30% mus rau ntau dua 100% siab dua li cov lim dej sintered, zoo heev txo cov voj voog lim thiab txhawb kev tsim khoom.
- Txo qhov siab poob: Thaum pib lub siab poob qis yog txo los ntawm 20% mus rau 50%, thiab qhov nce hauv siab poob thaum lub sij hawm thauj khoom tsis zoo yog qeeb dua. Qhov no ncua sij hawm ua haujlwm tau zoo thiab txo qhov kev siv hluav taws xob.
- Guaranteed muaj zog: Txawm hais tias muaj qhov porosity siab, qhov muaj zog ntawm titanium thiab qhov zoo tshaj plaws sintered caj dab kom ntseeg tau tias tensile thiab compressive lub zog ua tau raws li qhov xav tau ntawm siab - siab pulse backwashing thiab nquag ua haujlwm hloov pauv.
- Cov txiaj ntsig nyiaj txiag: Cov nqi ntws siab dua thiab kev pab cuam lub neej ntev dua (tsawg dua hloov zaus) txhais tau tias muaj txiaj ntsig zoo hauv tag nrho cov nqi ntawm cov tswv cuab.
4. Cov ntawv thov tseem ceeb
Cov yam ntxwv siab ntws, qis qis qis ua rau cov ntsiab lus tseem ceeb hauv cov xwm txheej hauv qab no:
High-Flow Pre-Kuaj Systems: Piv txwv li, pem hauv ntej- kawg tiv thaiv lim rau pub kwj hauv cov nroj tsuag tshuaj loj.
Siab -Viscosity Fluid Filtration: Piv txwv li, filtering polymer melts, resins, coatings, qhov uas tsis tshua muaj siab poob yog qhov tseem ceeb.
Cov Txheej Txheem Yuav Tsum Muaj Kev Rov Qab Rov Qab Los lossis Rov Ntxiv Hauv Online: Tsis tshua muaj siab poob tso cai rau kev rov qab zoo dua thiab rov tsim dua tshiab.
Daim ntawv thov Sensitive rau System Energy Consumption: Tsis tshua muaj siab poob ncaj qha txo cov twj tso kua mis zog.
Xaus
Lub ultra- tus nqi ntws siab thiab tsis tshua muaj siab poob tus yam ntxwv ntawm siab porosity titanium lim ntsiab tsis yog xwm txheej. Lawv tau tsim los ntawm kev nkag siab tob ntawm titanium hmoov metallurgy thiab kev ua tiav hauv cov txheej txheem tsim khoom. Los ntawm spherical hmoov grading mus rau ntau-theem gradient sintering tswj, txhua kauj ruam muaj xws li "precise sculpting" ntawm lub pore qauv. Nws sawv cev tsis yog tsuas yog ib qho kev ua haujlwm siab - kev ua haujlwm lim dej tab sis kuj tseem xav tau kev lag luam niaj hnub rau kev ua tau zoo thiab txuag hluav taws xob. Nrog rau kev sib koom ua ke ntawm cov txheej txheem tshiab xws li kev tsim khoom ntxiv (3D luam ntawv), kev tsim cov qauv pore hauv titanium lim yuav ua tau ntau yam, txuas ntxiv thawb cov ciam teb ntawm kev ua tau zoo thiab ua kom lawv lub luag haujlwm tseem ceeb hauv kev thov kom pom cov ntawv thov.
