Kev paub txog daim ntawv graphite
Daim ntawv graphite yog ib hom tshiabkev xa cua sovthiabkev tshem tawm cua sovcov khoom siv, uas tuaj yeem coj cua sov sib npaug zos hauv ob qho kev taw qhia, tiv thaiv cov khoom siv cua sov thiab cov khoom sib xyaw, thiab txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob rau cov neeg siv khoom. Nrog rau kev ua kom nrawm ntawm kev txhim kho cov khoom siv hluav taws xob thiab qhov kev thov loj hlob rau kev tswj cua sov ntawm mini,kev koom ua ke siabthiabkev ua tau zoo heevcov khoom siv hluav taws xob, peb lub tuam txhab tau tsim cov thev naus laus zis tshiab rau kev tshem tawm cua sov rau cov khoom siv hluav taws xob, uas yog, kev daws teeb meem tshiab rau kev tshem tawm cua sov graphite. Cov kua graphite tshiab no muaj qhov zoo ntawm kev ua haujlwm kub siab, kev ua haujlwm me me,lub teeb yuag, kev sib kis cua sov sib npaug ntawm ob qho kev taw qhia, tshem tawm cov cheeb tsam "kub kub", tiv thaiv cov khoom siv cua sov thiab cov khoom, thiab txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob rau cov neeg siv khoom. Cov kev siv tseem ceeb ntawm cov ntawv graphite yog raws li nram no: Nws yog siv rau hauv lub khoos phis tawj sau ntawv, lub teeb pom kev zoo LED siab, lub vijtsam tiaj tus, lub koob yees duab digital, xov tooj ntawm tes thiab cov khoom siv pabcuam tus kheej. Lub hauv paus ntsiab lus ntawm kev siv tshuab graphite fin heat dissipation yog raws li nram no: Lub luag haujlwm tseem ceeb ntawm daim ntawv graphite yog los tsim kom muaj thaj chaw loj uas cua sov raug xa mus thiab coj mus los ntawm cov khoom siv txias sab nraud. Lub dab dej cua sov graphite yog los ntawm kev faib cov cua sov sib npaug hauv lub dav hlau ob-seem, kom xa cov cua sov tau zoo, kom ntseeg tau tias cov khoom ua haujlwm hauv qab qhov kub. Cov yam ntxwv ntawm cov khoom: qhov saum npoo tuaj yeem ua ke nrog hlau, yas, tus kheej nplaum thiab lwm yam khoom siv, ntau yam kev tsim qauv thiab kev xav tau. Kev ua tau zoo heev ntawm cov thermal conductivity: 150-1200w / mk, zoo dua li ntawm cov hlau. Lub teeb yuag, qhov hnyav tshwj xeeb tsuas yog 1.0-1.3, mos, yooj yim rau kev khiav lag luam. Kev tiv thaiv thermal tsawg. Cov xim yog dub. Thickness: 0.012-1.0mm, nplaum: 0.03mm, thermal conductivity: plane conduction: 300-1200w / mk, vertical conduction: 20-30w / MKkev tiv thaiv kub: 400 ℃. Kev tiv thaiv thermal qis: qis dua 40% dua li txhuas thiab qis dua 20% dua li tooj liab; Lub teeb yuag: sib dua 25% dua li txhuas thiab sib dua 75% dua li tooj liab. Thiab raws li qhov xav tau ntawm cov neeg siv khoom ua txhua yam kev txiav. Qhov Ntim Resistivity ASTM D257Ω / CM 3.0 * 10; Hardness ASTM D2240 ntug dej A> 80
