Hauv cov txheej txheem kev lag luam niaj hnub no, kev ntseeg tau, kev ua haujlwm zoo thiab kev tswj hwm kev ua qias tuaj yog qhov tseem ceeb tshaj plaws, thiab kev siv tshuab sealing ua lub luag haujlwm tseem ceeb. Txij li cov chaw ua tshuaj lom neeg mus rau cov chaw tsim khoom semiconductor, lub sijhawm ua haujlwm ib txwm ntawm cov khoom siv feem ntau nyob ntawm ib qho me me tab sis tseem ceeb - kev ua haujlwm ntawm cov khoom siv tshuab.
Thaum cov txheej txheem kev lag luam tau nce qib zuj zus thiab qhov xav tau nce ntxiv, cov txheej txheem kaw ib txwm muaj (xws li cov foob pob) tau maj mam hloov los ntawm cov foob pob tshuab. Lub zog tsav tsheb tom qab qhov kev hloov pauv no yog los ntawm cov kev xav tau hauv qab no:
● Kev ua haujlwm siab dua
● Kev tswj kom zoo dua qub
● Lub neej ua haujlwm ntev dua
● Kev sib raug zoo nrog cov tshuaj lom neeg corrosive
● Kev siv hluav taws xob zoo dua
Thaum lub sijhawm txoj kev loj hlob no, kev tshawb fawb txog cov ntaub ntawv tau ua lub luag haujlwm tseem ceeb. Ntawm txhua yam khoom siv sib khi, cov khoom sib xyaw ua los ntawm carbon - tshwj xeeb tshaj yog carbon graphite - tau dhau los ua lub zog tseem ceeb rau cov txheej txheem sib khi ua haujlwm siab hauv kev lag luam tshuaj lom neeg, petrochemical thiab semiconductor.
Lub foob pob carbon-graphite yog dab tsi?
Cov roj hmab carbon graphite yog cov khoom siv sib khi uas tsim los ntawm kev ua tib zoo, feem ntau siv rau hauv cov khoom siv sib hloov xws li cov twj tso kua mis, cov tshuab compressors, thiab cov khoom sib tov. Lawv muaj cov nplhaib sib khi ruaj khov lossis tig ua los ntawm cov khoom siv carbon graphite.
Cov nplhaib sib khi no siv ua ke nrog cov khoom siv tawv ob yam (xws li silicon carbide lossis ceramics), tsim kom muaj qhov sib txuas sib khi uas tswj tau uas tiv thaiv cov kua dej lossis roj xau thaum tso cai rau kev txav mus los.
Lub luag haujlwm tseem ceeb ntawm cov pa roj carbon graphite seals yog kom muaj ib txheej nyias nyias ntawm cov zaj duab xis lubricating ntawm ob qho chaw, yog li ua kom ntseeg tau tias:
● Kev sib txhuam tsawg kawg nkaus
● Kev hnav uas tswj tau
● Tswj kev ua haujlwm sealing ruaj khov rau lub sijhawm ua haujlwm ntev
Vim li cas carbon graphite thiaj yog cov khoom siv zoo tshaj plaws rau cov khoom siv kho tshuab
Cov pa roj carbon graphite siv dav hauv cov tshuab kaw lus vim nws cov yam ntxwv tshwj xeeb ntawm lub cev thiab tribological. Tsis zoo li cov hlau lossis cov khoom siv ceramic, cov pa roj carbon graphite muaj lubricity thiab tuaj yeem tswj tau qhov ua tau zoo ruaj khov hauv qab ob qho tib si qhuav thiab ntub dej ua haujlwm.
Cov khoom tseem ceeb ntawm lub cev:
✔ Cov coefficient sib txhuam tsawg: 0.05 ~ 0.15
✔ Cov khoom siv lubricating tus kheej: Cov qauv siv lead ua los ntawm graphite
✔ Kev ruaj khov ntawm cua sov: Txog li 200–450 ° C (qib txheem), siab dua rau cov qib tshwj xeeb
✔ Tshuaj tiv thaiv: Zoo heev tiv taus cov kua qaub, alkalis thiab cov kuab tshuaj organic
✔ Lub zog compressive: Feem ntau 80–200 MPa (nyob ntawm hom impregnation)
✔ Ceev: 1.6 ~ 2.1 g / cm³
✔ PV txwv (siab × ceev): 10–200 bar·m/s (nyob ntawm qib)
Cov yam ntxwv no ua rau cov pa roj carbon graphite tsim nyog rau cov chaw sib khi hnyav, qhov twg cov ntaub ntawv ib txwm yuav tsis ua haujlwm vim hnav, xeb lossis thermal degradation.
Qhov tseem ceeb tshaj plaws yog qhov uas graphite ua rau nws tus kheej lubricating. Nws cov qauv atomic ua rau nws yooj yim rau txiav cov khaubncaws sab nraud povtseg, yog li ntawd txo qhov kev sib txhuam thiab kev hnav thaum lub sijhawm ua haujlwm.
Cov txheej txheem khoom siv rau cov roj carbon graphite
Cov roj carbon graphite mechanical seals tsis yog ib yam khoom siv xwb, tab sis yog ib qho ntawm cov khoom siv sib xyaw ua ke. Cov txheej txheem feem ntau siv suav nrog:
Cov roj carbon graphite uas muaj cov roj hmab:Haum rau kev siv rau hauv kev lag luam dav dav. Nws muaj cov yam ntxwv zoo heev uas nws tus kheej lubricating thiab muaj kev pheej yig zoo.
Cov pa roj carbon graphite uas muaj antimony:Nws muaj cov thermal conductivity thiab lub zog kho tshuab siab dua, thiab tsim nyog rau cov twj tso kua dej ceev lossis siab.
Cov hlau impregnated carbon graphite (tooj liab, nyiaj, thiab lwm yam):Tsim tshwj xeeb rau cov xwm txheej hnyav uas xav tau kev ua kom sov zoo dua thiab kev ruaj khov ntawm cov qauv.
Txhua lub tshuab tau raug kho kom zoo rau cov xwm txheej ua haujlwm tshwj xeeb (xws li kub, siab, kev sib raug zoo ntawm cov tshuaj lom neeg thiab kev sib hloov ceev).
Cov ntawv thov hauv kev lag luam semiconductor
Txawm hais tias cov khoom siv foob tsis yog ib feem ntawm cov khoom siv ua wafer, lawv ua lub luag haujlwm tseem ceeb hauv cov khoom siv semiconductor.
Cov roj carbon graphite mechanical seals siv dav hauv:
● Lub twj tso kua mis qhuav
● Lub tshuab xa tshuaj (HF, HCl, H₂SO₄, thiab lwm yam)
● CMP slurry xa khoom system
● Lub tshuab dej ntshiab heev (UPW)
● Cov khoom siv ua haujlwm ntub dej
Hauv cov kab ke no, qhov kev ntseeg tau ntawm kev sib khi ncaj qha cuam tshuam rau lub sijhawm ua haujlwm ib txwm ntawm lub Hoobkas wafer thiab kev tswj hwm kev ua qias tuaj. Txawm tias qhov xau me me lossis tsim cov khoom me me tuaj yeem ua rau muaj kev cuam tshuam loj heev lossis kev poob qis ntawm cov txiaj ntsig.
Yog li ntawd, cov roj carbon-graphite seals raug suav hais tias yog ib qho tseem ceeb hauv lub ecosystem tsim khoom semiconductor, vim lawv yog qhov tseem ceeb rau kev ntseeg tau.
Cov Khoom Siv Hluav Taws Xob Carbon Graphite thiab Semiconductor Graphite
Txawm hais tias ob qho tib si ntawm cov ntaub ntawv no yog ua los ntawm carbon, lawv cov tswv yim tsim thiab cov kev xav tau kev ua tau zoo sib txawv kiag li.
Cov pa roj carbon graphite mechanical seal:
● Tsom ntsoov rau tribology (kev sib txhuam, kev hnav, kev ua kom lubrication)
● Zoo rau kev txav mus los thiab kev sib txuas ntawm cov khoom siv sib khi
● Ua tau raws li qhov yuav tsum tau ua kom huv si nruab nrab
