Nekukura kuri kuita indasitiri yepasi rose nekukurumidza, upfu hwegirafiti hwave kuonekwa sechimwe chezvinhu zvakakosha zvezvicherwa zveindasitiri munyika nekunze kwenyika. Kunyanya mumakore achangopfuura, nekufambira mberi kwesainzi netekinoroji, girafiti yakaita basa guru mumaindasitiri akasiyana-siyana.
Muindasitiri, matombo egrafiti anoiswa muzvikamu zviviri zvikuru: matombo egrafiti akagadzirwa nekristaro uye matombo egrafiti akagadzirwa nekristaro akagadzikana. Mashizha egrafiti akagadzirwa nekristaro anogona kuiswa muzvikamu zviviri: akapfava uye akakora.
Matombo egrafiti muChina anonyanya kunge ari emhando yekristaro inoputsika, ichiteverwa nerudzi rwekristaro. Grafiti yakakora inowanikwa chete mumadhaka mashoma akadai seTokbula muXinjiang uye haina kukosha kukuru muindasitiri.
Graphite yemaindasitiri inochengetedza hunhu hwemakemikari hwepakutanga hwegraphite yeflake, kureva kuramba acid, kuramba ngura uye hunhu hwepanyama, pamwe nekudzivirira kupisa kwakanyanya nekwakaderera. Simba rayo rekudzvanya rinodarika 800kg/ cm², uye rinodzivirira oxidation. Rinorasikirwa ne1% yehuremu hwaro mumhepo ye450℃ uye rine rebound rate ye15-50%. Rinewo simba rakasimba rekuzvizora regraphite powder. Saka, graphite yakashandiswa zvakanyanya mukugadzira simbi, makemikari engineering, petrochemicals, high-energy physics, aerospace, electronics nedzimwe nzvimbo.
Vachishandisa hunhu hwegraphite, vanhu vakagadzira mhando dzakasiyana dzezvigadzirwa zvinoenderana nezvinodiwa nemainjiniya, zvakaita segraphite yakachena kwazvo, graphite inochinjika, graphite ine composite, nezvimwewo. Kuti iwedzere kushanda kwayo, graphite inosanganiswa nefibers, graphite metal waya, simbi meshes uye simbi working plates kugadzira graphite powder composite graphite, iyo inowedzera simba rayo uye elasticity.
Graphite yakagadzirwa necomposite inonyanya kudzvanywa kana kupiswa neresin, rabha dzekugadzira uye mapurasitiki. Kunewo graphite yemvura uye graphite yemvura.
Graphite inoita basa guru mumabasa akasiyana-siyana, akadai sekuvhara, kudzivirira kupisa, kudzivirira ngura, kufambisa magetsi, kuchengetedza kupisa, kudzivirira kumanikidzwa, kudzivirira kupera uye kudzivirira oxidation, izvo zvakakwezva kutariswa kukuru kubva kune nyanzvi dziri kumba nekune dzimwe nyika. Ehe, graphite iri kupindawo muhofisi yemazuva ano chinyararire. Semuenzaniso, fekitori yezvigadzirwa zvekuchengetedza zvinhu muJiangxi Province inoshandisa graphite kuiwedzera nekuigadzira kuita mapepa akatenderera asingapindi zvipembenene ane kugona kumwe kunyudza mishonga uye inogona kuramba ichishanda kwegore rose.
Nekuda kwekuwedzera kudiki kwegraphite uye kugona kwayo kutsungirira kuchinja kwekupisa nekukurumidza, inogona kushandiswa sechiumbwa chegirazi. Mushure mekushandisa graphite, macasting anowanikwa kubva kusimbi dzesimbi ane saizi chaiyo, nzvimbo dzakatsetseka, uye mwero wegoho guru. Anogona kushandiswa asina kana nekugadzirwa kudiki chete, nokudaro achichengetedza huwandu hwakawanda hwesimbi. Mukugadzirwa kwesimbi dzeupfu dzakadai sesimbi dzakaoma, mabhoti nemidziyo yekupisa inodzivirira kumanikidzwa zvinowanzogadzirwa nezvinhu zvegraphite. Pamusoro pezvo, graphite inogonawo kushandiswa se vacuum smelting graphite insulation plates nebases, pamwe nezvikamu zvakaita semachubhu efurnace anodzivirira kupisa kwakanyanya, tsvimbo, maplates, uye zvikamu.
