Ngokuthuthuka okusheshayo kwemboni yomhlaba, i-graphite powder ibhekwe njengenye yezinto ezibalulekile zamaminerali ezimbonini ekhaya nakwamanye amazwe. Ikakhulukazi eminyakeni yamuva nje, ngokuthuthuka kwesayensi nobuchwepheshe, i-graphite idlale indima ebalulekile ezimbonini ezahlukahlukene.
Embonini, amatshe e-graphite ahlukaniswa ngezigaba ezimbili ezinkulu: amatshe e-graphite acwebezelayo kanye namatshe e-graphite acwebezelayo acwebezelayo. Amatshe e-graphite acwebezelayo angahlukaniswa ngezinhlobo ezimbili: acwebezelayo kanye naqinile.
Amatshe e-graphite eShayina ikakhulukazi awohlobo lwekristalu oluqhekekile, alandelwe uhlobo lwe-cryptocrystalline. I-graphite ecwebezelayo ecwebezelayo itholakala kuphela ezindaweni ezimbalwa ezifana neTokbula eXinjiang futhi ayinani elincane lezimboni.
I-graphite yezimboni igcina izakhiwo zamakhemikhali zokuqala ze-flake graphite, okungukuthi ukumelana ne-asidi, ukumelana nokugqwala kanye nezakhiwo zomzimba, kanye nokumelana namazinga okushisa aphezulu naphansi. Amandla ayo okucindezela angaphezu kuka-800kg/ cm², futhi imelana ne-oxidation. Ilahlekelwa yi-1% yesisindo sayo emoyeni ongu-450℃ futhi inesilinganiso sokubuya esingu-15-50%. Iphinde ibe nokusebenza okunamandla kakhulu kokuzigcoba kwe-graphite powder. Ngakho-ke, i-graphite isetshenziswe kabanzi kwezensimbi, ubunjiniyela bamakhemikhali, amakhemikhali kaphethroli, ifiziksi yamandla aphezulu, izindiza, ama-elekthronikhi kanye neminye imikhakha.
Besebenzisa izakhiwo ze-graphite, abantu baye bakhiqiza ngobuhlakani izinhlobo ezahlukene zemikhiqizo ngokwezidingo zobunjiniyela, njenge-graphite ehlanzekile kakhulu, i-graphite eguquguqukayo, i-graphite ehlanganisiwe, njalo njalo. Ukuze kuthuthukiswe ukusebenza kwayo, i-graphite ihlanganiswa nemicu, izintambo zensimbi ze-graphite, ama-meshe ensimbi kanye namapuleti okusebenza ngensimbi ukuze kwakhiwe i-graphite powder composite graphite, okwandisa kakhulu amandla ayo kanye nokuqina kwayo.
I-graphite ehlanganisiwe icindezelwa kakhulu noma iboshwe ngokushisa ngama-resin, amarabha okwenziwa kanye namapulasitiki. Kukhona ne-graphite ewuketshezi kanye ne-graphite ewuketshezi oluyi-semi-liquid.
I-Graphite idlala indima ebalulekile emikhakheni ehlukahlukene, njengokuvala, ukumelana nokushisa, ukumelana nokugqwala, ukuhanjiswa kukagesi, ukulondolozwa kokushisa, ukumelana nengcindezi, ukumelana nokuguguleka kanye nokumelana nokushiswa kwe-oxidation, okudonsele ukunaka okukhulu kochwepheshe ekhaya nakwamanye amazwe. Yiqiniso, i-graphite nayo ingena ngokuthula ezintweni zehhovisi zesimanje. Isibonelo, ifektri yezimpahla zokugcina umlando eSifundazweni saseJiangxi isebenzisa i-graphite ukuyikhulisa nokuyicubungula ibe amashidi ayindilinga angangenwa yizinambuzane anekhono elithile lokumunca imithi futhi ingagcina ukusebenza kwayo unyaka wonke.
Ngenxa yokwanda okuncane kwe-graphite kanye nekhono layo lokubekezelela izinguquko zokushisa okusheshayo, ingasetshenziswa njengesikhunta sezinto zokugqoka zengilazi. Ngemva kokusebenzisa i-graphite, ama-castings atholakala ezinsimbini zensimbi anobukhulu obunembile, izindawo ezibushelelezi, kanye namazinga aphezulu okukhiqiza. Angasetshenziswa ngaphandle noma ngokucubungula okuncane kuphela, ngaleyo ndlela asindise inani elikhulu lensimbi. Ekukhiqizweni kwezinqubo ze-powder metallurgy ezifana ne-alloys eqinile, izikebhe nezitsha zokushisa ezimelana nokucindezela ngokuvamile zenziwe ngezinto ze-graphite. Ngaphezu kwalokho, i-graphite ingasetshenziswa futhi njenge-vacuum smelting graphite insulation plates kanye nezisekelo, kanye nezingxenye ezifana namashubhu esithando sokumelana nokushisa okuphezulu, izinduku, amapuleti, kanye nezindawo.
