Ii-electrode ze-graphite ezinamandla aphezulu kakhulu zisetyenziswe kakhulu kwezi zinto zilandelayo:
1. Ii-Graphite molds zokuphoswa okuqhubekayo kunye nokungaqhubekiyo kweentsimbi ezingezizo ezomileyo
Kwiminyaka yakutshanje, iindlela zemveliso eziphambili ezifana nokuveliswa ngokuthe ngqo (okanye okuqhubekekayo) kweebhari okanye iityhubhu ezivela kwimeko yesinyithi esinyibilikisiweyo ziye zakhuthazwa ekhaya nakwamanye amazwe. Le ndlela iqalile ukwamkelwa eTshayina kwiinkalo ezifana nobhedu, ii-alloys zobhedu, i-aluminium kunye nee-alloys ze-aluminium. I-graphite yokwenziwa ithathwa njengeyona nto ifanelekileyo kwiimolds zokuphosa eziqhubekekayo okanye eziqhubekekayo zeentsimbi ezingezizo i-ferrous. Indlela yokuvelisa ibonakalise ukuba ngenxa yokwamkelwa kweemolds ze-graphite, ezine-conductivity entle yobushushu (ukuqhuba kobushushu kumisela isantya sokuqina kweentsimbi okanye ii-alloys) kunye nokusebenza okuhle kokuthambisa kweemolds, isantya sokuphosa asikhuphuki nje kuphela, kodwa kwanokuba ubungakanani be-inget buchanekile, umphezulu uthambile, kwaye isakhiwo sekristale siyafana, inkqubo elandelayo yokucubungula inokwenziwa ngokuthe ngqo. Oku akukhuphukisi kakhulu kuphela isivuno seemveliso ezigqityiweyo kwaye kunciphisa ukulahleka kweemveliso zenkunkuma, kodwa kukwaphucula kakhulu umgangatho weemveliso.
Kukho iintlobo ezimbini zeendlela zokuphosa ngokuqhubekayo: ukuphosa ngokuqhubekayo ngokuthe nkqo kunye nokuphosa ngokuqhubekayo okuthe tye.
2. Iimbumba zokuphosa uxinzelelo
Izixhobo zegrafiti yokwenziwa zisetyenziswe ngempumelelo ekuphoseni ngoxinzelelo lweentsimbi ezingezizo i-ferrous. Umzekelo, izixhobo ze-zinc alloy kunye ne-copper alloy eziveliswa ziimolds ze-pressure casting ezenziwe ngezinto zegrafiti yokwenziwa zisetyenziswe kwiindawo zezithuthi nakwezinye izinto.
3. Idayi yokucinezela eshushu
Ii-dies ze-graphite ezishushu zokufakelwa zineempawu ezilandelayo xa zisetyenziswa ekutshiseni uxinzelelo lwe-carbide eqinisiweyo:
Okokuqala, ukuba ubushushu bokucinezela bunyuswa bufikelele kwi-1350-1450 degrees, uxinzelelo olufunekayo lweyunithi lungancitshiswa luye kwi-67-100 kg amandla ngesentimitha yesikwere (oko kukuthi, isinye kwishumi soxinzelelo lokucinezela olubandayo). Okwesibini, uxinzelelo kunye nokufudumeza kwenziwa ngendlela efanayo, kwaye umzimba oxineneyo osinkisiweyo ungafunyanwa emva kwexesha elifutshane lokusinki.
4. Iimbumba zokwenza iglasi
Ngenxa yokuzinza kweekhemikhali zezinto zegrafiti, ukumelana kwazo nokumanziswa yiglasi enyibilikisiweyo, kunye nenyaniso yokuba azitshintshi ukwakheka kweglasi, kunye nokumelana kwazo kakuhle nobushushu kunye notshintsho oluncinci kubushushu, ziye zaba zizinto zokubumba eziyimfuneko ekuvelisweni kweglasi kwiminyaka yakutshanje. Zingasetyenziselwa ukwenza ii-molds zeetyhubhu zeglasi, iityhubhu zengqiniba, ii-funnels, kunye nezinye iibhotile zeglasi ezinemilo ekhethekileyo.
5. Ii-Sintering dies kunye nezinye
Ukusebenzisa ithuba lokuguquguquka okuncinci kakhulu kobushushu bezinto ezenziwe ngegrafiti, ii-sintering molds kunye neebrackets zee-transistors zinokwenziwa. Ngoku isetyenziswa kakhulu kwaye ibe yinto efunekayo ekuphuhlisweni kweshishini le-semiconductor. Ukongeza, ii-graphite molds zikwasetyenziswa kwii-cast iron molds, ii-durable molds kwiintlobo ngeentlobo zeentsimbi ezingezizo i-ferrous, ii-molds zentsimbi ephosiweyo, ii-molds zeentsimbi ezimelana nobushushu (ezifana ne-titanium, i-zirconium, i-molybdenum, njl.njl.), kunye nee-molds zee-aluminothermic welding molds zee-welding rails, njl.njl.
6. Ii-Graphite molds zokwenza i-centrifugal casting
I-graphite yesikhunta isetyenziswe ngempumelelo kwi-centrifugal casting. I-United States yamkele ii-graphite zesikhunta ezenziweyo ezinobukhulu bodonga obungaphezulu kweemilimitha ezingama-25 ukuze kufakwe ii-centrifugal sleeves zebronze. Ukuthintela umonakalo otshayo wee-graphite zesikhunta ezenziweyo, amanyathelo athile okulwa ne-oxidation angathathwa. Emva kokuphosa inani elithile lee-castings, ukuba umphezulu wangaphakathi wesikhunta ufunyenwe utshile, ubungakanani bomngxuma wangaphakathi wesikhunta bunokwandiswa ukuze busetyenziswe ekuphoseni ii-sleeves ezinkulu. I-Qingdao Mingyuan Fengyue New Materials luhlobo olutsha lweshishini lokucubungula i-graphite elinomgubo we-flake graphite okumgangatho ophezulu njengomzimba walo oyintloko kunye neemveliso ze-graphite zobugcisa obuphezulu njengemveliso yalo ephambili. Iseke ubudlelwane bentsebenziswano bexesha elide neeyunithi zasekhaya nezangaphandle ezingaphezu kwama-200 kwaye inconywe kakhulu luninzi lwabasebenzisi.
Umgubo wegrafiti ye-nanometer wenziwe ngegrafiti yendalo ethambileyo njengezinto eziluhlaza, icutshungulwa ngokusebenzisa izixhobo ezikhethekileyo zokutyumza ngoomatshini kunye neendlela ezikhethekileyo zokuvelisa. Njengomgubo wegrafiti ye-nanoscale, umgubo wegrafiti ye-nanometer uneendlela ezininzi zokusetyenziswa ngenxa yobukhulu bayo obuncinci bamasuntswana, umxholo ophezulu wekhabhoni, kunye nokuthambisa okuphezulu okuphezulu, ukuqhuba kombane okuphezulu, ukumelana nobushushu obuphezulu, njl. Ububanzi bokusetyenziswa komgubo we-nano-graphite bukwimimandla yemveliso yemizi-mveliso efana nokuthambisa kunye nokuqhuba.
Iinxalenye zegrafiti ye-nanometer zilungile kwaye zinobunzima obuhle beenxalenye. Zenza umaleko wokukhusela oqinileyo nongagugiyo ohlanganiswe ngeekhemikhali kumphezulu wesinyithi. Zingaxutywa nezinto ezingaqhubiyo ezifana neeresini kunye neemveliso zerabha kunye neplastiki ukwenza izinto eziqhubiyo. Igrafiti ye-nanometer ingenziwa ibe ziingubo eziqhubiyo. Iingubo eziqhubiyo eziqhubiyo ezifunyenwe ngokongeza izizalisi eziqhubiyo zineempawu zombane ezihlala ixesha elide nezizinzileyo. Inezibonelelo zokuqhuba kakuhle kobushushu, ukuqhuba kakuhle kombane kunye nokumelana nokugqwala okuphezulu kakhulu. Igrafiti ye-nanometer inobungakanani obufanayo beenxalenye, ubunyulu obuphezulu, kunye nomsebenzi ophezulu womphezulu. Ikwanokuqhuba okuphezulu kombane kunye nokusebenza kokuthambisa, kunye nokumelana nobushushu obuphezulu, ukumelana nokugqwala, kunye nokuzinza kweekhemikhali kwepowder yegrafiti. Ke ngoko, umda wokusetyenziswa kwepowder yegrafiti ye-nanometer ubanzi kakhulu kushishino.
Ukusetyenziswa komgubo we-nano-graphite ekulungiseni iibhetri zokugcina nako kubanzi kakhulu. Ukongeza i-nano-graphite kwiibhetri ezisetyenzisiweyo kunokunyusa amandla azo okugcina aye ngaphezulu kwe-90% yoqobo kwaye kwandise ubomi bazo benkonzo ubuncinane ngonyaka omnye. Oku kusindisa kakhulu iindleko zokusetyenziswa kweebhetri zokugcina kwaye kudlala indima ebalulekileyo ekulawuleni ungcoliseko lwebhetri kunye nokukhuselwa kokusingqongileyo.
Umgubo wegrafiti uneendlela ezahlukeneyo zokusetyenziswa kushishino. Ungasetyenziswa kwiindawo ezahlukeneyo zemveliso kushishino. Ukusetyenziswa okuhlukeneyo komgubo wegrafiti kubangela amaxabiso ahlukeneyo. Umgubo wegrafiti uneziphumo ezilungileyo zokusetyenziswa kwiindawo ezifana nokuthambisa i-industrial, i-metallurgy, i-conductivity, kunye nezinto ezichaseneyo. Izinto ezifana nokusetyenziswa, ubungakanani bamasuntswana, kunye nohlobo lomgubo wegrafiti zonke zinokuchaphazela ixabiso lawo.
Ukusetyenziswa komgubo wegrafiti kwahlukile, ngoko ke kukho iintlobo ezininzi zomgubo wegrafiti. Iintlobo ezahlukeneyo zomgubo wegrafiti zinamaxabiso ahlukeneyo. Igrafiti yeflake ingacutshungulwa ibe ngumgubo wegrafiti oneempawu ezahlukeneyo kunye nobukhulu beesuntswana ngokusebenzisa izixhobo ezahlukeneyo zokutyumza kunye neendlela zokwenza imveliso. Njengomvelisi womgubo wegrafiti, iinkcukacha zomgubo wegrafiti ovelisiweyo ziqala kwi-80 mesh ukuya kwi-15000 mesh. Umgubo wegrafiti uneempawu ezahlukeneyo kunye nobukhulu beesuntswana, kwaye nexabiso lawo linjalo. Emva kokuba ucutshungulwe ngeendlela zokwenza imveliso, umgubo wegrafiti une-lubricity egqwesileyo, ukumelana nobushushu obuphezulu, ukuqhuba kombane, ukumelana nokugqwala, njl. Umgubo wegrafiti unokudlala indima efanayo kwiindawo ezahlukeneyo zemveliso kushishino.
Iindidi zepowder yegrafiti ziquka: umgubo wegrafiti oyiflake, umgubo wegrafiti oyi-ultrafine, umgubo wegrafiti ye-nano, igrafiti ye-colloidal, igrafiti eyandisiweyo, igrafiti enokukhuliswa, igrafiti encinci yomgubo, njl.njl., zonke ezi powder zegrafiti zicutshungulwa ngeendlela ezahlukeneyo zemveliso, kwaye ukusetyenziswa kwazo kwahlukile. Umgubo wegrafiti usetyenziswa kwiindawo zemveliso yeoyile yokuthambisa, izinto zokuthambisa eziqinileyo, izinto zokuthambisa zegrafiti, izitena ezichaseneyo, ii-electrode zegrafiti, iibhrashi, ii-electrode ezinebhetri, njl. Zonke zinezicelo ezilungileyo kakhulu.
