Graphite ntawv yog dav siv nyob rau hauv cov khoom siv hluav taws xob, thiab graphite ntawv yog siv rau ntau qhov chaw kom dissipate tshav kub. Graphite ntawv tseem yuav muaj teeb meem kev pab cuam lub neej thaum siv, tsuav yog txoj kev siv kom raug tuaj yeem ua tau zoo dua rau kev pab cuam lub neej ntawm graphite ntawv. Tus editor hauv qab no yuav piav qhia rau koj txog txoj hauv kev kom txuas ntxiv lub neej kev pabcuam ntawm graphite ntawv:
1. Graphite daim ntawv tuaj yeem txuas mus rau qhov sib npaug ntau li ntau tau. Yog hais tias tus nqi ntawm cov ntawv graphite tsis zoo ib yam, cov graphite phaj nrog siab tsis kam yuav yog concentrated nyob rau hauv series, uas ua rau ib tug ceev ceev nyob rau hauv cov kev tiv thaiv ntawm ib co graphite ntawv thiab ib tug luv luv lub neej.
2. Qhov ntau dua qhov tam sim no siv rau daim ntawv graphite, qhov kub ntawm daim ntawv graphite ntau dua. Nws raug nquahu kom siv qhov tsawg tshaj plaws ntawm qhov chaw thau khoom ceev (lub zog). Thov nco ntsoov tias tus nqi kaw ntawm qhov txias kawg ntawm daim ntawv graphite yog qhov tam sim no thiab qhov hluav taws xob ntawm 1000 ℃ hauv huab cua, uas tsis yog raws li daim ntawv thov tiag tiag. Raws li ib txwm muaj, lub zog saum npoo ntawm daim ntawv graphite tau txais los ntawm kev sib raug zoo ntawm qhov kub thiab txias hauv qhov cub thiab qhov kub thiab txias. Nws raug nquahu kom siv lub zog saum npoo (W / cm2) ntawm 1/2 ~ 1/3 ntawm qhov txwv qhov ntom ntom ntawm graphite phaj, thiab cov ntawv kub kub resistant graphite.
3. Thaum siv daim ntawv graphite tsis tu ncua, nws cia siab tias yuav ua kom muaj kev tiv thaiv maj mam ua kom lub neej ntev.
4. Rau cov yam ntxwv ntawm qhov kub thiab txias ntawm cov ntawv graphite, cov qauv tshuaj ntsuam xyuas yog tias nws nyob hauv 60 ° C nyob rau hauv qhov kub kub ntev. Tau kawg, qhov kub ntawm qhov sib faib 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 qhov sib txawv ntawm cov huab cua thiab kev ua haujlwm hauv lub cub tawg.
5. Tom qab daim ntawv graphite yog rhuab nyob rau hauv cov huab cua, ib tug ntom silicon oxide zaj duab xis yog tsim nyob rau saum npoo, tsim ib tug anti-oxidative tiv thaiv zaj duab xis, uas plays lub luag hauj lwm nyob rau hauv lub neej ntev. Nyob rau hauv xyoo tas los no, ntau yam txheej txheej tau tsim los kom tsis txhob tawg ntawm daim ntawv graphite siv rau hauv qhov cub nrog ntau yam roj.
6. Qhov siab dua qhov kev ua haujlwm kub ntawm graphite ntawv, lub neej ua haujlwm luv dua. Yog li ntawd, tom qab qhov cub kub kub tshaj 1400 ° C, oxidation tus nqi yuav nrawm dua thiab kev pabcuam lub neej yuav luv. Thaum siv, ceev faj kom tsis txhob cia qhov kub ntawm daim ntawv graphite siab dhau.
Cov ntawv graphite uas tsim los ntawm Furuite graphite yog tsim los ntawm kev nthuav dav graphite los ntawm dov thiab ci, thiab muaj qhov kub thiab txias, thermal conductivity, yooj, resilience thiab sealing zoo. Yog tias koj muaj kev xav tau kev yuav khoom, thov koj xav nug.
