Graphite yog lub thawv ua los ntawm ceramics, yog li nws muaj qhov kub thiab txias tsis kam thiab tuaj yeem siv rau hauv kev lag luam hlau sealing lossis casting. Lub thermal conductivity yog qhov zoo, tab sis nws tsuas yog oxidized thiab qhov kev puas tsuaj loj, thaum silicon carbide cymbal piv nrog graphite daim phiaj ntim thiab muaj lub neej ntev kev pab cuam.
Ntau tus neeg tsis tau preheated thaum lawv siv cov graphite tshiab 时, ua rau graphite tawg, uas ua rau muaj kev phom sij rau koj tus kheej kev nyab xeeb thiab kev ruaj ntseg ntawm cov khoom.
1. Cov graphite tshiab siv thawj 4-5 teev los muab tso rau hauv lub qhov cub roj kom preheat, uas yuav pab tau lub dehumidifier nto.
2. Muab charcoal los yog ntoo rau hauv lub pupa li plaub teev ua ntej siv cov graphite tshiab. Nws yog pab los ntawm dehumidification.
3. Lub sij hawm sov so ntawm qhov cua sov hauv lub cub tawg tshiab yog raws li nram no: 0 degree -200 degree qeeb cua sov 4H roj 0 degree -300 degree qeeb cua sov 1h hluav taws xob 200 degree -300 degree Slow kub 4H rauv 300 degree -300 degree - 800 degree Slow kub 4H rauv 300 degree -400 degree qeeb cua sov 4h 400 degree -600 degree Ceev ceev cua sov thiab txuas ntxiv 2H
4. Tom qab lub cub tawg nres, lub sij hawm preheating yog raws li nram no: roj rauv thiab hluav taws xob rauv: 0 degree -300 degree qeeb kub ntawm 1h 300 degree -600 degree qeeb cua sov 4H 600 degree - Ua kom kub ceev kom txog qhov yuav tsum tau kawm A. Hluav taws xob rauv. : Nws yog qhov zoo los khaws cov rwb thaiv tsev thaum lub sijhawm ua haujlwm nres, thiab qhov kub thiab txias yog teem rau ntawm 600 ° C; yog tias koj tsis khaws cov cua sov, koj yuav tsum tau nplawm kom ntau li ntau tau yam tsis tau tawm ntau dhau; Yog tias koj ntsib lub zog, koj yuav tsum tau tshem tawm cov khoom agile. b. Roj rauv: Tom qab lub qhov cub nres, cov kua zaub yuav tsum tau ntxuav kom ntau li ntau tau.
