Hav nyob ntawd! Raws li tus neeg muag khoom ntawm Graphite Thermal Sheets, Kuv feem ntau tau nug yog tias cov nplooj ntawv no tiv taus qhov kub thiab txias. Zoo, cia peb dhia mus rau hauv nws thiab nrhiav kom paub.
Ua ntej tshaj, cia peb nkag siab tias Graphite Thermal Sheets yog dab tsi. Graphite yog ib daim ntawv ntawm cov pa roj carbon, thiab cov nplooj ntawv no yog tsim los ntawm kev taw qhia pyrolytic graphite (HOPG) lossis lwm yam graphite - raws li cov ntaub ntawv. Lawv tau tsim los hloov cov cua sov kom zoo, uas yog ib qho tseem ceeb heev nyob rau hauv ib pawg ntawm kev lag luam.
Graphite Thermal Sheets muaj qee qhov zoo nkauj zoo nkauj thaum nws los txog rau cua sov. Graphite nws tus kheej muaj qhov siab melting point. Qhov tseeb, lub melting point ntawm graphite yog nyob ib ncig ntawm 3652 - 3697℃(6606 - 6687℃F). Qhov siab melting point no muab peb ib qho zoo nkauj qhia tias Graphite Thermal Sheets tuaj yeem tswj tau qhov kub thiab txias.
Thaum nws los txog rau tiag - ntiaj teb daim ntawv thov, Graphite Thermal Sheets yog siv nyob rau hauv ntau yam kub - ib puag ncig. Piv txwv li, hauv kev lag luam hluav taws xob, raws li cov khoom siv hluav taws xob tau me dua thiab muaj zog dua, lawv ua kom muaj cua sov ntau. Graphite Thermal Sheets yog siv los ua kom cov cua sov no. Lawv tuaj yeem tiv taus qhov kub siab uas tsim los ntawm cov txheej txheem, cov duab kos, thiab lwm yam khoom tsis muaj degrading.
Hauv kev lag luam tsheb, ib yam nkaus, cov ntawv no pom lawv siv. Cov cav tsim hluav taws xob ua kom sov, thiab Graphite Thermal Sheets tuaj yeem siv los tswj cov cua sov no. Lawv tuaj yeem tswj tau qhov kub thiab txias hauv qab lub hood, kom ntseeg tau tias cov khoom siv cav ua haujlwm tau zoo thiab tsis txhob overheat.
Tam sim no, cia peb tham txog kev tshawb fawb tom qab lawv siab - qhov kub thiab txias. Graphite muaj cov qauv siv lead ua tshwj xeeb. Nws muaj cov txheej txheem ntawm carbon atoms teem rau hauv hexagonal lattice. Cov khaubncaws sab nraud povtseg tau tuav ua ke los ntawm cov tsis muaj zog van der Waals. Thaum tshav kub kub siv, cov pa roj carbon atoms tuaj yeem co thiab hloov lub zog cua sov los ntawm cov qauv lattice. Cov qauv no tso cai rau Graphite Thermal Sheets ua cov cua sov kom zoo thiab tseem ua rau lawv muaj peev xwm tiv taus qhov kub thiab txias.
Txawm li cas los xij, tsis yog txhua lub hnub ci thiab zaj sawv. Thaum Graphite Thermal Sheets muaj kev tiv thaiv siab rau qhov kub thiab txias, muaj qee qhov kev txwv. Hauv cov pa oxygen - nplua nuj ib puag ncig, ntawm qhov kub thiab txias, graphite tuaj yeem hnov mob nrog oxygen thiab oxidize. Oxidation tuaj yeem ua rau cov graphite tawg dhau sijhawm. Tab sis nyob rau hauv feem ntau cov ntawv thov kev lag luam, cov kauj ruam tau ua los tiv thaiv qhov no. Piv txwv li, cov nplooj ntawv tuaj yeem coated nrog cov khoom siv tiv thaiv - oxidation los yog siv rau hauv ib puag ncig tsis muaj roj.
Lwm qhov yuav tsum tau xav txog yog qhov purity ntawm graphite. Siab dua - purity graphite feem ntau yuav muaj qhov zoo dua siab - kub tsis kam. Cov impurities hauv graphite tuaj yeem txo nws cov ntsiab lus melting thiab cuam tshuam rau nws qhov kev ua tau zoo tag nrho ntawm qhov kub thiab txias. Yog li, ua tus xa khoom, peb paub tseeb tias yuav siv siab - purity graphite hauv peb cov Graphite Thermal Sheets los xyuas kom meej qhov ua tau zoo tshaj plaws.
Cia peb saib qee yam khoom lag luam hauv peb cov khoom lag luam graphite. Peb kuj muab Pob Zeb Diamond Sintering Pwm. Cov pwm no yog siv los tsim cov khoom siv pob zeb diamond. Lawv yuav tsum tiv taus qhov kub thiab txias thaum lub sij hawm sintering, thiab ib yam li peb cov Graphite Thermal Sheets, lawv yog tsim los ntawm siab - zoo graphite kom ntseeg tau siab - kub tsis kam.
Peb kuj muaj cov cuab yeej pob zeb diamond. Cov cuab yeej no yog siv rau hauv ntau yam txiav, sib tsoo, thiab drilling daim ntawv thov. Graphite Cheebtsam hauv cov cuab yeej no yuav tsum muaj peev xwm tswj tau qhov kub thiab txias uas tau tsim thaum lub sijhawm ua haujlwm no, thiab peb cov khoom muaj nyob rau ntawm txoj haujlwm.
Thiab tom qab ntawd muaj Graphite Gasket. Gaskets yog siv los kaw cov pob qij txha thiab tiv thaiv kom tsis txhob yaig. Nyob rau hauv siab - daim ntawv thov kub, xws li nyob rau hauv industrial furnaces los yog pipelines nqa cov dej kub, cov gaskets yuav tsum tau tswj lawv cov kev ncaj ncees. Peb Graphite Gaskets yog tsim los ntawm siab - graphite zoo thiab tuaj yeem tiv taus qhov kub thiab txias, ua kom muaj kev ruaj ntseg zoo.
Hauv kev xaus, Graphite Thermal Sheets yeej tiv taus qhov kub thiab txias. Lawv cov qauv graphite tshwj xeeb, cov ntsiab lus melting siab, thiab cov cua sov ua haujlwm tau zoo- hloov cov khoom ua rau lawv tsim nyog rau ntau yam kev siv kub -. Tau kawg, muaj qee qhov kev txwv, tab sis nrog kev tuav kom raug thiab xaiv cov khoom siv, cov no tuaj yeem kov yeej.
Yog tias koj nyob hauv kev ua lag luam rau siab - Graphite Thermal Sheets lossis ib qho ntawm peb cov khoom siv graphite, kuv xav hnov los ntawm koj. Txawm hais tias koj yog cov chaw tsim khoom siv hluav taws xob, lub tuam txhab tsheb, lossis los ntawm lwm qhov kev lag luam uas xav tau kev tswj xyuas cov cua sov, peb tuaj yeem muab cov khoom zoo rau koj. Tsuas yog ncav cuag, thiab peb tuaj yeem pib sib tham txog koj cov kev xav tau tshwj xeeb thiab seb peb Graphite Thermal Sheets tuaj yeem haum rau koj daim ntawv thov. Peb nyob ntawm no los pab koj daws koj cov teeb meem kub - thiab xyuas kom meej tias koj cov khoom lag luam zoo.
