Isiphumo kunye nenzuzo yezinto ezibonakalayo zeemveliso zegrafiti
Ngenxa yeempawu zayo ezininzi ezibalaseleyo, i-graphite isetyenziswa kakhulu kumacandelo e-metallurgical, mechanical, electric, chemical, textile, kunye namanye amacandelo emizi-mveliso. Isebenza njengesixhobo esichasayo kwaye igcina iimpawu zokuqala zeekhemikhali ze-flake graphite ngelixa ibonisa iimpawu eziqinileyo zokuzithambisa. Umgubo we-graphite ubonakaliswa kukumelana ne-asidi enamandla aphezulu, ukumelana nokugqwala, ukunyamezela ubushushu obuphezulu ukuya kuthi ga kwi-3000℃ kunye nokumelana nobushushu obuphantsi ukuya kuthi ga kwi--204℃. Ukongeza, inamandla okucinezelwa angaphezulu kwe-800kg/Cm2 kwaye ibonisa ukumelana ne-oxidation kunye nokulahlekelwa bubunzima yi-1% kuphela xa ivezwa emoyeni kwi-450℃. Ngaphezu koko, ibonisa izinga lokubuya kwe-15-50% (ubuninzi be-1.1-1.5). Ngenxa yoko, iimveliso ze-graphite zisetyenziswa kakhulu kwi-metallurgy, kushishino lweekhemikhali, kushishino lwe-petrochemical, kwi-physics yamandla aphezulu, kwi-aerospace, kwi-electronics nakwezinye iinkalo ezahlukeneyo.
Iimveliso zegrafiti ngokwazo zinezibonelelo ezinkulu kakhulu:
1, iimveliso zegrafayithi zine-adsorption elungileyo.
Ulwakhiwo lwekhabhoni olungenanto lwenza ikhabhoni ibe nokufunxwa okuhle, ngoko ke ikhabhoni idla ngokusetyenziswa njengesixhobo sokufunxwa kwamanzi, ivumba, izinto ezinobuthi njl.njl. Senze iimvavanyo, kwiintsuku ezimbalwa ezidlulileyo itreyi yokubhaka yegrafiti esetyenzisiweyo kwi-barbecue ibonakala icocekile kakhulu, kodwa xa uyibeka kwi-induction oven, uza kubona ukufunxwa kwegrisi kunye nezinto ezinobungozi kwi-barbecue yokugqibela kuya kuphuma kancinci kancinci, kodwa ungakhathazeki, nephepha lokutya elicocekileyo lokusula lingasetyenziswa.
2, iimveliso zegrafiti zinomoya ofudumeleyo olungileyo, udluliselo lobushushu olukhawulezayo, ubushushu obufanayo, ukonga amafutha.
Iishiti zokubhaka kunye neepani ezenziwe ngegrafiti zifudunyezwa ngokukhawuleza, kwaye ukutya okutshisiweyo kufudunyezwa ngokulinganayo, kuphekwe ngaphakathi nangaphandle, kwaye ixesha lokufudumeza lifutshane, kungekuphela nje ukuba incasa icocekile, kodwa kwanezondlo zokuqala zokutya zinokutshixwa. Senze iimvavanyo, xa ipani yegrill yegrafiti isetyenziselwa ukurosta, isitofu sokungenisa sitshisa umlilo ekuqaleni, kwaye sinokufudunyezwa kwimizuzwana engama-20-30 kuphela, kwaye xa ukutya kuqaliwe, kungadlalwa kumlilo omncinci, onokugcina amandla.
3, iimveliso zegrafiti zinozinzo lweekhemikhali kunye nokumelana nokugqwala.
I-Graphite inamandla okumelana neekhemikhali kubushushu begumbi kwaye ayihlaselwa yi-asidi enamandla, isiseko esomeleleyo kunye nesinyibilikisi sendalo. Ke ngoko, nokuba ukusetyenziswa kwexesha elide kweemveliso ze-graphite akunalahleko ingako, lo gama nje isusiwe yacoceka njengentsha.
Iimveliso zegrafiti ezi-4 zinefuthe elinamandla lokulwa ne-oxidation kunye nokunciphisa.
Iimveliso, ingakumbi ukufudumeza umatrasi ngegrafayithi, zinokuvelisa ii-ion zeoksijini ezingalunganga, zenze izinto ezingqongileyo zisebenze, zigcine impilo yabantu, zithintele ukwaluphala ngempumelelo, zenze ulusu luzaliswe kukukhazimla nokuthamba.
5, imveliso yegrafayithi impilo yokusingqongileyo, akukho ungcoliseko lwe-radioactive, ukumelana nobushushu obuphezulu.
Ikhabhoni ingaba yigrafiti emva kweentsuku ezilishumi elinesibini nobusuku begrafiti kwindawo enobushushu obuphezulu obuyi-2000-3300 degrees, ngoko ke izinto ezinobungozi neziyingozi kwigrafiti sele zikhutshiwe kwaye zizinzile ngaphakathi kwe-2000 degrees ubuncinane.
Kwangaxeshanye, iimveliso zegrafiti ngenxa yesakhiwo sayo esikhethekileyo, ezinokumelana nobushushu obuphezulu, ukumelana nokutsha kobushushu, ukuqhuba kombane, ukuthambisa, ukuzinza kweekhemikhali kunye nokuqina kweplastiki kunye nezinye iimpawu ezininzi, ziye zaba sisixhobo esibalulekileyo sobuchule ekuphuhlisweni koshishino lomkhosi nolwanamhlanje kwaye ubuchwepheshe obuphezulu, obutsha nobubukhali, iimveliso zegrafiti, ezifana neeringi zegrafiti, iinqanawa zegrafiti zisetyenziswa kakhulu. Iingcali zamazwe ngamazwe ziye zaqikelela ukuba "inkulungwane yama-20 yinkulungwane yesilicon, inkulungwane yama-21 iya kuba yinkulungwane yekhabhoni."
Njengemveliso ebalulekileyo yeminerali engeyiyo eyesinyithi, ishishini legrafiti liza kuphunyezwa ulawulo lokufikelela. Ngokusetyenziswa kwenkqubo yokufikelela, igrafiti, iimveliso zegrafiti, ziya kuba zezinye emva kwe-rare earth, i-fluorine chemical, i-phosphorus chemical, iinkampani eziphambili kweli candelo ziya kungena kwinqanaba elitsha lophuhliso.
