Daim ntawv graphite siv dav hauv cov khoom siv hluav taws xob, thiab daim ntawv graphite siv ntau qhov chaw los tso cua sov. Daim ntawv graphite kuj tseem yuav muaj teeb meem lub neej ua haujlwm thaum siv, tsuav yog txoj kev siv kom raug tuaj yeem ua kom daim ntawv graphite ntev dua. Tus kws kho hauv qab no yuav piav qhia rau koj txog txoj hauv kev kom raug los ua kom daim ntawv graphite ntev dua:
1. Daim ntawv graphite tuaj yeem txuas ua ke ntau li ntau tau. Yog tias tus nqi tsis kam ntawm daim ntawv graphite tsis zoo ib yam, daim ntawv graphite uas muaj kev tsis kam siab yuav raug sib sau ua ke, ua rau daim ntawv graphite qee yam muaj kev tsis kam sai thiab lub neej luv dua.
2. Qhov ntau ntawm cov tam sim no siv rau daim ntawv graphite, qhov siab dua qhov kub ntawm daim ntawv graphite. Nws raug pom zoo kom siv qhov tsawg tshaj plaws ntawm qhov ceev ntawm qhov chaw (lub zog). Thov nco ntsoov tias tus nqi sau tseg ntawm qhov kawg txias ntawm daim ntawv graphite yog qhov tam sim no thiab qhov hluav taws xob ntawm 1000 ℃ hauv huab cua, uas tsis sib xws nrog daim ntawv thov tiag tiag. Hauv qab qhov xwm txheej ib txwm muaj, lub zog ntawm daim ntawv graphite tau txais los ntawm kev sib raug zoo ntawm qhov kub hauv lub cub tawg thiab qhov kub ntawm qhov chaw. Nws raug pom zoo kom siv lub zog ntawm qhov chaw (W / cm2) ntawm 1/2 ~ 1/3 ntawm qhov txwv ntawm cov phaj graphite, thiab daim ntawv graphite tiv taus kub siab.
3. Thaum siv daim ntawv graphite tas li, nws vam tias yuav ua rau qhov kev tiv thaiv qeeb qeeb kom tswj tau lub neej ntev.
4. Rau cov yam ntxwv ntawm kev faib tawm kub ntawm daim ntawv graphite, tus qauv tshuaj xyuas yog tias nws nyob hauv 60 ° C hauv qhov ntev kub kub. Tau kawg, qhov kev faib tawm kub yuav nce ntxiv nrog nws cov laus, thiab nws tuaj yeem ncav cuag 200 ° C. Cov kev hloov pauv kub tshwj xeeb kuj txawv vim yog huab cua sib txawv thiab cov xwm txheej ua haujlwm hauv lub cub tawg.
5. Tom qab daim ntawv graphite raug cua sov hauv huab cua, ib zaj duab xis silicon oxide ntom ntom tau tsim rau ntawm qhov chaw, tsim ib zaj duab xis tiv thaiv oxidative, uas ua lub luag haujlwm hauv kev txuas ntxiv lub neej. Nyob rau hauv xyoo tas los no, ntau yam txheej txheem tau tsim los kom tsis txhob tawg ntawm daim ntawv graphite rau kev siv hauv cov cub tawg nrog ntau yam roj.
6. Qhov kub ntawm daim ntawv graphite ua haujlwm siab dua, lub neej ua haujlwm luv dua. Yog li ntawd, tom qab qhov kub ntawm lub cub tawg tshaj 1400 ° C, qhov oxidation yuav raug nrawm dua thiab lub neej ua haujlwm yuav luv dua. Thaum siv, ceev faj kom tsis txhob cia qhov kub ntawm daim ntawv graphite siab dhau.
Daim ntawv graphite uas tsim los ntawm Furuite graphite yog ua los ntawm cov graphite nthuav dav los ntawm kev dov thiab ci, thiab muaj kev tiv taus kub siab, kev ua kom sov, kev ywj pheej, kev ua kom muaj zog thiab kev sib khi zoo. Yog tias koj muaj kev xav tau kev yuav khoom, thov koj xav nug.
