Iphepha le-graphite lenziwe nge-carbon flake graphite ephezulu ngokwelashwa kwamakhemikhali kanye nokuguquguquka kokwanda kwezinga lokushisa. Ukubukeka kwayo kubushelelezi, ngaphandle kwamabhamuza asobala, imifantu, imibimbi, imihuzuko, ukungcola nezinye iziphambeko. Kuyinto eyisisekelo yokwakhiwa kwezimpawu ezihlukahlukene ze-graphite. Isetshenziswa kabanzi ekubekeni uphawu okuguquguqukayo nokumile kwemishini, amapayipi, amaphampu nama-valve emandleni kagesi, i-petroleum, amakhemikhali, i-instrumentation, imishini, idayimane nezinye izimboni. Kuyinto entsha ekahle yokuvala ukufaka uphawu esikhundleni sezimpawu zendabuko ezifana nerabha, i-fluoroplastics kanye ne-asbestos. .
Ukucaciswa kwephepha le-graphite ikakhulukazi kuncike ekugqineni kwalo. Iphepha le-graphite elinokucaciswa okuhlukene nobukhulu linokusetshenziswa okuhlukile. Iphepha le-graphite lihlukaniswe libe yiphepha le-graphite eliguquguqukayo, iphepha le-graphite elincanyana kakhulu, iphepha le-graphite elivaliwe, iphepha le-graphite le-thermal conductive, iphepha eliqhutshwayo le-graphite, njll.
Izici ezi-6 zephepha le-graphite:
1. Ukucutshungulwa kalula: Iphepha le-graphite lingasikwa libe ngosayizi abahlukene, ubujamo nobukhulu, futhi amabhodi ayisicaba anqunyiwe anganikezwa, futhi ubukhulu bungasukela ku-0.05 kuye ku-1.5m.
2. Ukumelana nokushisa okuphezulu: izinga lokushisa eliphezulu lephepha legraphite lingafinyelela ku-400 ℃, futhi ubuncane bungaba ngaphansi kuka -40℃.
3. Ukushisa okuphezulu kwe-thermal conductivity: I-conductivity ephezulu ye-thermal e-plane yephepha le-graphite ingafinyelela ku-1500W / mK, futhi ukumelana nokushisa kungu-40% okuphansi kune-aluminium kanye ne-20% ephansi kuneyethusi.
4. Ukuguquguquka: Iphepha le-graphite lingenziwa kalula libe ngama-laminates ngensimbi, ungqimba oluvikelayo noma i-tape enezinhlangothi ezimbili, okwandisa ukuguquguquka kokuklama futhi ingaba ne-adhesive ngemuva.
5. Ukukhanya nokubancane: Iphepha le-graphite lilula ngo-30% kune-aluminium enosayizi ofanayo futhi lilula ngo-80% kunethusi.
6. Ukusetshenziswa kalula: I-graphite heat sink ingaxhunywa ngokushelela kunoma iyiphi indawo eyisicaba futhi egobile.
Lapho ugcina iphepha le-graphite, naka lezi zindaba ezimbili ezilandelayo:
1. Indawo yokugcina izinto: Iphepha le-graphite lifaneleka kakhulu ukuba libekwe endaweni eyomile neyisicaba, futhi alichaywanga elangeni ukuze livinjwe ukuthi lingakhanywa. Ngesikhathi sokukhiqiza, kunganciphisa ukushayisana; inezinga elithile le-conductivity, ngakho uma idinga ukugcinwa, kufanele igcinwe kude nomthombo wamandla. ucingo lukagesi.
2. Vimbela ukuphuka: Iphepha le-graphite lithambile kakhulu ekuthunjweni, singalisika ngokuvumelana nezidingo, ukuze zivimbele ukuba zingaphuli ngesikhathi sokugcina, alifanelekile ukugoqa noma ukugoba nokugoqa nge-angle encane. Imikhiqizo yephepha elijwayelekile le-graphite ifanele ukusika kube amashidi.
