Kwiindawo zokulinganisa ngokuchanekileyo, ukukhethwa kwezinto kubalulekile ukuqinisekisa ukuchaneka okuphindaphindwayo, uzinzo lobushushu, kunye nokuthembeka kwexesha elide. Phakathi kwezixhobo zemetrology eziphezulu, izixhobo zokulinganisa i-alumina ceramic kunye nezixhobo zokulinganisa i-granite zezona zikhetho zimbini ziphambili zokuhlolwa kwelabhoratri kunye nokulinganiswa kwamacandelo.
Eli nqaku lihlola utshintshiselwano phakathi kwezi zinto kwizicelo ezichanekileyo kakhulu, ligqamisa iimpawu zazo zomzimba kunye nokufaneleka kwazo kwiimeko zokulinganisa ezinobuzaza ezifana neenqwelo moya kunye nezixhobo ze-semiconductor.
Zithini Izixhobo Zokulinganisa zeAlumina Ceramic kunye neGranite?
Izixhobo ze-Alumina Ceramic
Iiseramikhi zeAlumina (Al₂O₃) zizixhobo zobunjineli eziphambili ezaziwa ngezi zinto zilandelayo:
- Ubunzima obuphezulu kakhulu (3–4× obufana nobegranite)
- I-coefficient ephantsi kakhulu yokwandiswa kobushushu (CTE)
- Ukumelana nokuguguleka okungaqhelekanga kunye nokukrwela
- Ukungangeni kweekhemikhali kunye nokumelana nokugqwala
Ii-alumina ceramics, ezidla ngokwenziwa zibe zizikwere ze-ceramic, iibhloko, kunye neepleyiti zesalathiso, zibonelela ngejometri efanayo phantsi kweemeko ezingqongileyo ezinzima.
Izixhobo zeGranite
Izixhobo zokulinganisa i-granite, ezenziwe nge-granite emnyama enoxinano olukhulu, zisasetyenziswa kakhulu ngenxa yezi zinto zilandelayo:
- Uzinzo oluphezulu lwendalo oluthe tyaba
- Ukunciphisa ukudlidliza okugqwesileyo
- Ukuziphatha okungekho magnethi
- Ukusebenza kakuhle kweendleko xa kuthelekiswa neeseramikhi eziphambili
I-granite isetyenziswa ngokwesiko kwizicelo zokuchaneka kwe-000-grade kwiilabhoratri zolawulo lomgangatho kunye nezibonelelo zokulinganisa.
1. Ukuqina kunye nokumelana nokunxiba
Iiseramikhi zeAlumina zinobunzima obumalunga ne-1200–1400 HV, xa kuthelekiswa ne-400–500 HV yegranite.
Iziphumo ze-metrology:
- Izixhobo zeseramikhi ziyamelana nemikrwelo, ukuqhekeka, kunye nokuguquguquka okubangelwa kukudibana rhoqo nezixhobo zesinyithi okanye izixhobo ezichanekileyo.
- Imiphezulu yegranite ichaphazeleka lula xa kujongwa iindawo apho kukho abantu abaninzi okanye apho kukho umthwalo omninzi, nto leyo enokuchaphazela ukuba tyaba ngokuhamba kwexesha.
Kwiilabhoratri ezilinganisa izinto zeenqwelo-moya, iindawo zenjini, okanye ii-semiconductor substrates, izixhobo zeseramikhi zigcina ukuthembeka kwejometri ixesha elide.
2. Ukwandiswa kobushushu: Ukunciphisa impazamo yokulinganisa
Ukutshintshatshintsha kobushushu kwiilabhoratri zokuhlola kunokubangela utshintsho kubukhulu bomphezulu obhekisele kuwo.
| Ipropati | I-Alumina Ceramic | Igranite |
|---|---|---|
| Ukwanda kwe-Thermal Coefficient | 4–6 × 10⁻⁶ /°C | 7–9 × 10⁻⁶ /°C |
| Uzinzo olunemilinganiselo | Igqwesile | Phezulu |
| Ukufaneleka kokulinganisa ubushushu obufanelekileyo | Ifanelekile | Iphakathi |
Inzuzo: Ukwanda okuphantsi kobushushu kwi-alumina ceramics kuqinisekisa ukuphindaphindeka kwe-sub-micron, ngakumbi kubaluleke kakhulu xa kulinganiswa i-aerospace echanekileyo kakhulu okanye izinto ezibonakalayo apho notshintsho oluncinci lobushushu lunokuphazamisa ukunyamezelana.
3. Ukumelana neekhemikhali kunye nokuzinza komphezulu
Iiseramikhi ze-Alumina azinazo iikhemikhali, azichaphazeleki yile:
- Izinto zokupholisa kunye neeoyile
- Iiarhente zokucoca elebhu
- Umswakama kunye nezinto ezingcolisayo emoyeni
I-granite, nangona imelana neekhemikhali ezininzi, inokuchaphazeleka kukuvezwa ixesha elide kwizinto ezine-asidi okanye i-alkaline, ezinokuthi zitshintshe kancinci kancinci ukuba umphezulu ube tyaba.
4. Ukukhetha i-Flatness kunye neGrade
Zombini izixhobo ze-alumina ceramic kunye ne-granite ziyafumaneka ngobuchule obuphezulu, zilungele ukuhlolwa ngobuchule obuphezulu.
Izikwere zeCeramic (精密陶瓷方箱) ukusuka kunikezelo lwealumina:
- Iindawo zoqhagamshelwano ezizinzileyo kakhulu zokulinganisa igeyiji
- Ukugcinwa kwe-flatness yexesha elide okuphezulu
- Ukunciphisa isidingo sokuphinda uhlengahlengise rhoqo
Izixhobo zeGranite 000-grade, nangona zichaneke kakhulu, zinokufuna uhlengahlengiso oluthe rhoqo kwiindawo ezisebenzisa izixhobo eziphezulu okanye ubushushu obuguquguqukayo.
5. Imeko zokusetyenziswa: Apho iCeramic iphumelela khona
