Iphepha legraphite lisetyenziswa kakhulu kwizixhobo zombane, kwaye iphepha legraphite lisetyenziswa kwiindawo ezininzi ukuphelisa ubushushu. Iphepha legraphite liya kuba nengxaki yobomi benkonzo ngexesha lokusetyenziswa, nje ukuba indlela yokusetyenziswa echanekileyo inokwandisa ubomi benkonzo yephepha legraphite. Umhleli olandelayo uya kukuchazela indlela echanekileyo yokwandisa ubomi benkonzo yephepha legraphite:
1. Iphepha legraphite linokudityaniswa ngokuhambelana kangangoko kunokwenzeka. Ukuba ixabiso elichasayo lephepha legraphite alifani, ipleyiti yegraphite enokumelana okuphezulu iya kugxininiswa kuthotho, okukhokelela ekunyukeni ngokukhawuleza kokuchaswa kwephepha elithile legraphite kunye nobomi obufutshane.
2. Ixabiso elikhulu langoku elisetyenziswe kwiphepha legraphite, liphezulu izinga lokushisa lephepha legraphite. Kucetyiswa ukuba kusetyenziswe ubuninzi obuncinci bomthwalo womphezulu (amandla). Nceda uqaphele ukuba ixabiso elirekhodiweyo ekupheleni okubandayo kwephepha legraphite likhoyo ngoku kunye ne-voltage kwi-1000 ℃ emoyeni, engahambelani nesicelo sangempela. Kwiimeko eziqhelekileyo, amandla angaphezulu kwephepha legraphite afunyenwe kubudlelwane phakathi kweqondo lokushisa kwisithando somlilo kunye nobushushu bomhlaba. Kucetyiswa ukuba usebenzise amandla angaphezulu (W/cm2) we-1/2 ~ 1/3 yoxinaniso lomda wepleyiti yegraphite, kunye nephepha legraphite elixhathisa ubushushu obuphezulu.
3. Xa usebenzisa iphepha legraphite ngokuqhubekayo, kunethemba lokunyusa ukuchasana ngokuthe ngcembe ukugcina ubomi obude.
4. Kwiimpawu zokusasazwa kobushushu bephepha legraphite, umgangatho wokuhlolwa kukuba ungaphakathi kwe-60 °C ngaphakathi kobude obusebenzayo bomkhuhlane. Ngokuqinisekileyo, ukuhanjiswa kwamaqondo obushushu kuya kwanda ngokuguga kwayo, kwaye ekugqibeleni kunokufikelela kuma-200 °C. Utshintsho oluthile lokusasazwa kweqondo lokushisa lukwahluke ngenxa yomoya ohlukeneyo kunye neemeko zokusebenza kwisithando somlilo.
5. Emva kokuba iphepha le-graphite lifudumale emoyeni, ifilimu edibeneyo ye-silicon oxide yenziwa phezu komhlaba, yenza ifilimu yokukhusela i-anti-oxidative, edlala indima ekwandiseni ubomi. Kwiminyaka yakutshanje, kuye kwaveliswa iintlobo ezahlukeneyo zokwaleka ukuze kuphetshwe ukuqhekeka kwephepha legraphite ukuze lisetyenziswe kwiziko elineegesi ezahlukeneyo.
6. Ukuphakama kobushushu bokusebenza kwephepha legraphite, bufutshane ubomi benkonzo. Ngoko ke, emva kokuba ukushisa kwesithando somlilo kudlula i-1400 ° C, izinga le-oxidation liya kukhawuleziswa kwaye ubomi benkonzo buya kufinyezwa. Ngethuba lokusetyenziswa, qaphela ukuba ungavumeli ukushisa kwephepha legraphite libe phezulu kakhulu.
Iphepha legraphite eliveliswe yiFuruite graphite lenziwe ngegraphite eyandisiweyo ngokuqengqeleka kunye nokugcadwa, kwaye inokumelana nobushushu obuphezulu, i-thermal conductivity, ukuguquguquka, ukomelela kunye nokutywinwa kakuhle. Ukuba unazo naziphi na iimfuno zokuthenga, nceda uzive ukhululekile ukubuza.
