Ndezvipi zvinhu zvakanaka zvegrafiti yakawedzerwa

1, basa reMichina:
1.1Kusimba kwakanyanya uye kusimba: kune zvigadzirwa zvegrafiti zvakawedzera, kuchine nzvimbo dzakawanda dzakavhurika dzakavharwa dzinogona kusimbiswa nesimba rekunze. Panguva imwe chete, dzine simba rekutsungirira nekuda kwekumanikidzwa kwemhepo munzvimbo diki dzakavhurika.
1.2Kuchinjika: kuomarara kwacho kwakaderera zvikuru. Inogona kuchekwa nezvishandiso zvakajairika, uye inogona kupurwa nekukotamiswa zvisina tsarukano;
2, Mabasa emuviri nemakemikari:
2.1 Kuchena: huwandu hwekabhoni hwakagadzika hunenge 98%, kana kutopfuura 99%, izvo zvakakwana kuzadzisa zvinodiwa zvekuchena kwakanyanyazvisimbiso mumagetsi nemamwe maindasitiri;
2. Kuwanda: iyokuwanda kwehuwanduye flake graphite i1.08g/cm3, huwandu hwakawanda hwe expanded graphite i0.002 ~ 0.005g/cm3, uye huwandu hwechigadzirwa i0.8 ~ 1.8g/cm3. Saka, expanded graphite texture yakareruka uye ipurasitiki;
3. Kudzivirira tembiricha: maererano nedzidziso, girafiti yakawedzerwa inogona kutsungirira - 200 ℃ kusvika 3000 ℃. Sechisimbiso chekurongedza, inogona kushandiswa zvakachengeteka pa - 200 ℃ ~ 800 ℃. Ine mabasa akanaka ekusava netsvina, kusachembera patembiricha yakaderera, kusanyorova, kusachinja-chinja uye kusaora patembiricha yakakwira;
4. Kuramba ngura: ine utera hwemakemikari. Pamusoro pekupisa kwakasiyana-siyana kwema oxidants akasimba akadai se aqua regia, nitric acid, sulfuric acid uye halogen, inogona kushandiswa kune zvakawanda zvakaita se acid, alkali, salt solution, mvura yegungwa, steam uye organic solvent;
5. Kufambisa kwakanaka kwazvo kwekupisauye chidimbu chidiki chekuwedzera kwekupisa. Maparamita ayo ari pedyo nehukuru hwakafanana hwedata rezvikamu zviviri zvemidziyo yese yekuvharira. Inogonawo kuvharwa zvakanaka mumamiriro ekushanda ekupisa kwakanyanya, cryogenic uye kuchinja kukuru kwekupisa;
6. Kudzivirira mwaranzie: inosangana nemwaranzi ye neutron γ Ray α Ray β X-ray irradiation kwenguva yakareba pasina shanduko yakajeka;
7. Kusapinda: kusapinda zvakanaka kwegasi nemvura. Nekuda kwesimba guru repamusoro regirafiti yakawedzerwa, zviri nyore kugadzira firimu regasi rakatetepa kana firimu remvura kuti zvisapinde zvakanaka;
8. Kuzvizora mafuta pachako: graphite yakawedzerwa ichiri kuchengetedza chimiro che hexagonal plane layers. Pasi pesimba rekunze, plane layers dziri nyore kutsvedza uye kuzvizora kunoitika, izvo zvinogona kudzivirira kupera kweshaft kana vharuvhu.
