Cov Nplhaib Sib Tsoo Uas Muaj Hlau Txhawb Nqa Alumina Ceramic Rau Kev Siv Lapping Rigidity Siab

St.Cera'shlau raws li alumina sib tsoo nplhaibua ke cov txheej txheem hnav ceramic alumina uas muaj qhov huv siab (99.8% Al₂O₃) nrog rau cov hlau uas ua los ntawm kev siv tshuab ua kom raug (feem ntau yog txhuas lossis hlau tsis xeb). Qhov kev tsim sib xyaw no muab qhov kev tiv thaiv kev hnav thiab kev tsis muaj zog ntawm cov tshuaj ceramic ntawm qhov chaw sib tsoo, thaum lub hauv paus hlau ntxiv lub zog kho tshuab, yooj yim rau kev teeb tsa, thiab tiv taus kev tawg yooj yim. Cov txheej txheem alumina muab lub zog flexural ntawm 361 MPa, Vickers hardness ntawm 16 GPa, thiab thermal stability txog li 800 ° C. Lub hauv paus hlau tau hloov kho nrog cov qhov mounting, cov pins nrhiav, lossis cov khoom sib nqus rau kev koom ua ke rau hauv cov tshuab lapping, planetary grinders, thiab cov khoom siv CMP.

Cov Lus Qhia Tshwj Xeeb(Txheej alumina raws li 99.8% Al₂O₃):

Lus Cim: Cov yam ntxwv ntawm cov hlau (qhov ceev, Young's modulus, thiab lwm yam) tsis tau muab tso rau hauv cov lus qhia txog cov khoom siv ceramic. Lawv ua raws li cov ntaub ntawv kev lag luam tus qauv rau txhuas/hlau. Thov qhia meej txog hom hlau thiab cov kev cai rau kev teeb tsa.

Cov ntawv thov:

● Lub tshuab sib tsoo planetary lapping

● CMP (chemical mechanical polishing) backing rings

● Kev sib tsoo tiaj tiaj ntawm cov foob ceramic lossis hlau

● Cov khoom siv sim kev hnav tsis zoo

Txheej Txheem Tsim Khoom:

1. Lub nplhaib alumina ceramic yog sintered los ntawm 99.8% hmoov thiab precision av mus rau qhov kawg ID / OD thiab flatness.

2. Lub hauv paus hlau yog CNC machined nrog mounting qhov, counterbores, lossis keyways.

3. Lub nplhaib ceramic yog sib txuas rau lub hauv paus hlau siv cov epoxy muaj zog heev (kev pabcuam kub ≤200 ° C) lossis clamped mechanically (tso cai rau qhov kub siab dua, txog li 500 ° C yog tias siv cov hlau shims).

4. Kev txhuam zaum kawg ntawm qhov chaw ceramic kom ua tiav qhov tiaj tiaj thiab qhov chaw tiav.

5. Kev ntxuav ultrasonic thiab 100% kev tshuaj xyuas qhov ntev.

Kev Tswj Xyuas Zoo:

● Kev tshuaj xyuas CMM ntawm ID, OD, tuab, thiab qhov chaw ntawm lub qhov

● Kev ntsuas qhov tiaj tiaj siv laser interferometer

● Kev sim lub zog sib txuas (kev sim rub tawm lossis kev sim txiav ntawm cov qauv pov thawj)

● Kev kuaj xyuas seb puas muaj qhov tawg lossis qhov khoob hauv cov txheej ceramic

Cov txiaj ntsig zoo dua li All-Ceramic lossis All-Metal Rings:

● Cov nplaim ceramic kav ntev dua 5–10 × dua li cov hlau uas tau kho kom ruaj khov

● Lub hauv paus hlau ua rau nws yooj ywm - tsis muaj kev pheej hmoo ntawm kev tawg thaum lub sijhawm teeb tsa

● Yooj yim mounting (qhov threaded, dowel pins) ncaj qha rau ntawm cov tshuab uas twb muaj lawm

● Tus nqi qis dua li lub nplhaib ceramic tag nrho rau cov kab uas hla loj

● Lub hauv paus hlau tuaj yeem tsim los rau kev txuas lub chuck sib nqus

Cov kev txwv (cov lus tseem ceeb):

● Cov ntaub ntawv txog cov hlau (kev nthuav dav ntawm cua sov, kev tawv) tsis yog los ntawm cov rooj ceramic uas muab los - saib cov khoom siv hlau txheem.

● Qhov kub siab tshaj plaws uas siv tas mus li raug txwv los ntawm kev sib txuas epoxy (≤200°C rau tus qauv epoxy; kev clamping tshuab tso cai rau txog li 500°C tab sis txo qhov kev sib khi).

● Tsis haum rau cov chaw muaj tshuaj lom neeg uas tawm tsam cov hlau (piv txwv li, cov kua qaub muaj zog). Yog xav kom tiv taus tshuaj lom neeg tag nrho, qhia meej tias yog lub nplhaib ceramic.

Kev Kho Kom Haum:

● Khoom siv hlau: txhuas (sib dua), hlau tsis xeb (tiv taus xeb), lossis Invar (nthuav dav thermal tsawg)

● Txoj kev sib txuas: epoxy (≤200°C), mechanical clamp (≤500°C), lossis brazed ceramic-to-metal (≤800°C, kim dua)

● Cov yam ntxwv ntawm kev teeb tsa: cov qhov threaded, cov qhov dowel pin, cov qhov, lossis cov hlau nplaum backing

● Cov txheej ceramic tuab: 3–20 hli
