Iielectrode zegraphite zamandla aphezulu kakhulu zisetyenziswe ngokubanzi kule miba ilandelayo:
1. Imibumbo yegraphite yokuphosa ngokuqhubekayo kunye nesiqingatha esiqhubekayo sesinyithi esingeyontsimbi
Kwiminyaka yakutshanje, iindlela zokuvelisa eziphambili ezinje ngokuqhubekayo ngokuthe ngqo (okanye isiqingatha-eqhubekayo) ukwenziwa kwemivalo okanye iityhubhu ezivela kwimeko yesinyithi etyhidiweyo ziye zakhuthazwa kokubini ekhaya nakwamanye amazwe. Le ndlela sele iqalile ukwamkelwa e-China kwiinkalo ezifana nobhedu, i-alloys zethusi, i-aluminium kunye ne-aluminium alloys. Igraphite eyenziweyo ithathwa njengeyona nto ifanelekileyo kwimibumbo eqhubekayo okanye engapheliyo yeentsimbi ezingenayo i-ferrous. Ukwenziwa kwemveliso kubonakalise ukuba ngenxa yokwamkelwa kokubumba kwegraphite, okunokuhanjiswa kakuhle kwe-thermal (i-thermal conductivity imisela isantya sokuqina kwesinyithi okanye i-alloys) kunye nokusebenza kakuhle kokuzithambisa kokubumba, ayisiyiyo kuphela isantya sokuphosa sandisiwe, kodwa nangenxa yokuba ubungakanani be-inget buchanekile, umphezulu ugudile, kwaye inkqubo yecrystalline inokuqhutywa ngokuthe ngqo. Oku akukona nje ukwandisa kakhulu isivuno seemveliso ezigqityiweyo kunye nokunciphisa ilahleko yeemveliso zenkunkuma, kodwa kuphucula kakhulu umgangatho weemveliso.
Kukho iintlobo ezimbini zeendlela eziqhubekayo zokuphosa: ukuphosa okuthe nkqo okuqhubekayo kunye nokuphosa okuthe tye okuqhubekayo.
2. Imingundo yokuphosa uxinzelelo
Izinto ezenziweyo zegraphite zisetyenziswe ngempumelelo kuxinzelelo lokuphoswa kweentsimbi ezingenayo i-ferrous. Ngokomzekelo, i-zinc alloy kunye ne-alloy castings eveliswa yi-press cast casting molds eyenziwe ngemathiriyeli yegraphite eyenziweyo isetyenziswe kwiindawo zemoto kunye neminye imiba.
3. Ukucofa okutshisayo kufa
Uxinzelelo olushushu lwegraphite eyenziweyo lunezi mpawu zilandelayo xa zisetyenziswa kuxinzelelo lwe-sintering ye-cemented carbide:
Okokuqala, ukuba iqondo lokushisa elicinezelayo liphakanyiswe kwii-degrees ze-1350-1450, uxinzelelo lweyunithi olufunekayo lunokuncitshiswa ukuya kwi-67-100 kilograms force per square centimeter (oko kukuthi, isahlulo seshumi soxinzelelo olubandayo). Okwesibini, uxinzelelo kunye nokufudumeza kwenziwa kwinkqubo efanayo, kwaye umzimba oxineneyo we-sintered unokufumaneka emva kwexesha elifutshane lokutshisa.
4. Imingundo yokwenza iglasi
Ngenxa yozinzo lwekhemikhali yezixhobo zegraphite, ukuxhathisa kwabo ukumanzisa ngeglasi etyhidiweyo, kunye nenyaniso yokuba abaguquli ukubunjwa kweglasi, kunye nokuxhathisa ukothuka kwe-thermal kunye notshintsho oluncinci lobushushu, baye baba yimpahla yokubumba eyimfuneko kwimveliso yeglasi kwiminyaka yakutshanje. Zingasetyenziselwa ukwenza imibumba yeetyhubhu zeglasi, iityhubhu zengqiniba, iifunnels, kunye nezinye iibhotile zeglasi ezimilise okwezodwa.
5. Sintering uyafa kunye nabanye
Ukuthatha ithuba le-thermal deformation encinci ye-artificial ye-graphite, iimolds ze-sintering kunye nezibiyeli ze-transistors zingenziwa. Ngoku isetyenziswa ngokubanzi kwaye iye yaba yinto eyimfuneko kuphuhliso lweshishini le-semiconductor. Ukongeza, iimolds zegraphite zikwasetyenziselwa ukubumba intsimbi etyhidiweyo, i-molds ehlala ixesha elide kwiintsimbi ezahlukeneyo ezingenayo i-ferrous, i-molds yentsimbi etyhidiweyo, i-molds yentsimbi ekwazi ukumelana nobushushu (njenge-titanium, i-zirconium, i-molybdenum, njl.)
6. Imilo yegraphite yokuphosa i-centrifugal
Igraphite yokungunda isetyenziswe ngempumelelo kwi-centrifugal casting. IUnited States iye yasebenzisa imilo yegraphite eyenziweyo enobunzima obungaphezu kweemilimitha ezingama-25 ukuze kufakwe imikhono yobhedu. Ukuthintela umonakalo ovuthayo wokubumba kwegraphite eyenziweyo, amanyathelo athile okulwa ne-oxidation anokuthathwa. Emva kokuphosa inani elithile le-castings, ukuba umgangatho wangaphakathi wesikhunta ufunyaniswa utshiswa, ubungakanani bomngxuma ongaphakathi wokubumba bunokwandiswa ukuze kusetyenziswe ukuphosa imikhono emikhulu. I-Qingdao Mingyuan Fengyue iziXhobo eziNtsha luhlobo olutsha lweshishini lokulungisa igraphite enomgangatho ophezulu we-flake ye-graphite powder njengomzimba wayo ophambili kunye neemveliso eziphezulu ze-graphite njengemveliso ekhokelayo. Iseke ubudlelwane bentsebenziswano bexesha elide kunye neeyunithi ezingaphezu kwama-200 zasekhaya nezangaphandle kwaye iye yanconywa kakhulu luninzi lwabasebenzisi.
I-Nanometer graphite powder yenziwe nge-flake yendalo yegraphite njengesixhobo ekrwada, isetyenzwa ngesixhobo esikhethekileyo sokutyumza ngoomatshini kunye nobuchule obukhethekileyo bokuvelisa. Njengoko i-nanoscale graphite powder, i-nanometer graphite powder inoluhlu olubanzi lwezicelo ngenxa yobukhulu bayo obuncinci, umxholo wekhabhoni ephezulu, kunye ne-lubricity ephezulu, ukuhanjiswa kombane okuphezulu, ukumelana nobushushu obuphezulu, njl njl.
I-Nanometer graphite particles ilungile kwaye inobuninzi be-particle. Benza umaleko oqinileyo kwaye phantse onganxibiyo okhuselayo odityaniswe ngokwekhemikhali kumphezulu wesinyithi. Zinokudityaniswa nezinto ezingezizo ezokuqhuba ezifana nentlaka kunye nerabha kunye neemveliso zeplastiki ukwenza izinto ezidityanisiweyo. I-nanometer graphite nayo inokwenziwa kwiingubo zokuqhuba. Iingubo ezidibeneyo ezidibeneyo ezifunyenweyo ngokufaka iifayili ze-conductive zinezixhobo zombane ezizinzileyo kunye nezizinzileyo. Ineengenelo zokuqhuba kakuhle kwe-thermal, i-conductivity egqwesileyo yombane kunye nokumelana nokugqwesa okuphezulu kakhulu. I-nanometer graphite inobukhulu obufanayo besuntswana, ubunyulu obuphezulu, kunye nomsebenzi ophezulu womphezulu. Ikwabonisa ukusebenza kombane okuphezulu kunye nokusebenza kokuthambisa, kunye nokumelana nobushushu obuphezulu, ukumelana nokunxiba, kunye nokuzinza kweekhemikhali zegraphite powder. Ngoko ke, umda wokusetyenziswa kwe-nanometer graphite powder ubanzi kakhulu kwishishini.
Ukusetyenziswa kwe-nano-graphite powder ekulungiseni iibhetri zokugcina nazo zininzi kakhulu. Ukongeza i-nano-graphite kwiibhetri ezisetyenzisiweyo kunokunyusa amandla abo okugcina ngaphezu kwe-90% ye-original kunye nokwandisa ubomi babo benkonzo ubuncinane ngonyaka omnye. Oku kusindisa kakhulu iindleko zokusetyenziswa kweebhetri zokugcina kwaye kudlala indima ebalulekileyo kulawulo longcoliseko lwebhetri kunye nokhuseleko lokusingqongileyo.
I-graphite powder inoluhlu olubanzi lwezicelo kwishishini. Ingasetyenziswa kwiinkalo ezahlukeneyo zemveliso yamashishini. Ukusetyenziswa okwahlukeneyo komgubo wegraphite kubangela amaxabiso ahlukeneyo. I-graphite powder ineziphumo ezilungileyo zokusetyenziswa kwiinkalo ezifana nokuthambisa kwimizi-mveliso, i-metallurgy, i-conductivity, kunye nezixhobo ezichasayo. Izinto ezifana nokusetyenziswa, ubungakanani besuntswana, kunye nohlobo lwepowder yegraphite inokuchaphazela ixabiso layo.
Ukusetyenziswa kwe-graphite powder kuyahluka, ngoko ke zininzi iintlobo ze-graphite powder. Iindidi ezahlukeneyo ze-graphite powder zinamaxabiso ahlukeneyo. I-Flake graphite inokucutshungulwa ibe ngumgubo wegraphite yeenkcazo ezahlukeneyo kunye nobukhulu bamasuntswana ngokusebenzisa izixhobo ezahlukeneyo zokutyumza kunye nobuchule bokuvelisa. Njengomenzi womgubo wegraphite, iinkcukacha zomgubo wegraphite oveliswayo usuka kwi-80 mesh ukuya kwi-15000 mesh. I-graphite powder ineenkcazo ezahlukeneyo kunye nobukhulu bamasuntswana, kunye nexabiso layo. Emva kokucutshungulwa ngobuchule bokuvelisa, umgubo wegraphite unokuthambisa okugqwesileyo, ukumelana nobushushu obuphezulu, ukuhanjiswa kombane, ukuxhathisa kokutya, njl njl.
Iindidi ze-graphite powder zibandakanya: i-Flake graphite powder, i-ultrafine graphite powder, i-nano graphite powder, i-colloidal graphite, i-graphite eyandisiweyo, i-graphite eyandisiweyo, i-micro-powder graphite, njl. Umgubo wegraphite usetyenziswa kwimimandla yemveliso ye-oyile yokuthambisa, izithambiso eziqinileyo, iicrucibles zegraphite, izitena eziphikisayo, i-electrode yegraphite, iibhrashi, i-electrode engalunganga yebhetri, njl.njl Zonke zinezicelo ezintle kakhulu.
