Sechinhu chitsva chinoshanda kabhoni, yakawedzera graphite (EG) chinhu chakasununguka uye chine porous worm-sechinhu chinowanikwa kubva kune zvakasikwa graphite flakes kuburikidza nekupindirana, kuwacha, kuomesa uye kuwedzera-tembiricha yekuwedzera.Pamusoro pezvinhu zvakanakisa zvechisikigo graphite senge kutonhora nekupisa kupisa, corrosion resistance uye self-lubrication, EG inewo hunhu hwekupfava, compression resilience, adsorption, ecological and environment coordination, biocompatibility uye radiation kuramba iyo yakasikwa graphite haina. have.Kare sekutanga kwema1860s, Brodie akawana yakawedzera graphite nekudziisa yakasikwa graphite nemakemikari reagents senge sulfuric acid uye nitric acid.Zvisinei, kushandiswa kwayo kwakatanga pashure pemakore zana.Kubva ipapo, nyika zhinji dzakatevedzana dzakaita tsvakiridzo nekusimudzira yegirafu yakawedzera uye vakaita budiriro huru yesainzi.

Yakawedzerwa graphite inogona kuwedzera pakarepo 150 ~ 300 nguva muhuwandu pakupisa kwepamusoro, uye kuchinja kubva kune flaky kusvika kune vermicular, zvichiita kuti yakasununguka chimiro, porous uye curved, yakawedzerwa nzvimbo yepamusoro, kuvandudzwa kwesimba repamusoro, kuwedzerwa kushambadza kweflake graphite, uye self-chimerism pakati. vermicular graphite, iyo inowedzera kushanduka kwayo, kusimba uye plastiki.
Nzira dzinoverengeka dzekusimudzira graphite yakawedzerwa ndeaya anotevera:

1. Girafu yakawedzerwa nokuda kwezvinangwa zvakakosha
Ongororo dzinoratidza kuti graphite worms ane basa rekutora mafungu emagetsi, izvo zvinoita kuti girafu rakawedzerwa rive nehukuru hwekushandisa kwemauto.Vese mauto eUS nemauto edu vakaita ongororo yekuyedza munzvimbo ino.Iyo yakawedzerwa graphite inofanirwa kuzadzisa zvinotevera zvinodiwa: (1) yakaderera yekutanga yekuwedzera tembiricha uye yakakura yekuwedzera vhoriyamu;(2) Chigadzirwa chemakemikari chakagadzikana, uye mwero wekuwedzera hauna kuora mushure memakore mashanu ekuchengetedza;(3) Iyo yepamusoro yegirafu yakawedzerwa haina kwayakarerekera uye haina ngura kune iyo cartridge kesi.

2. Granular yakawedzera graphite
Diki-particle yakawedzerwa graphite inonyanya kureva 300-chinangwa chinowedzerwa girafu ine vhoriyamu yekuwedzera ye100ml/g.Ichi chigadzirwa chinonyanya kushandiswa pamoto-retardant coatings, uye kudiwa kwayo kwakakura.

3. Yakawedzerwa graphite nepamusoro pekutanga kuwedzera tembiricha
Iyo yekutanga tembiricha yekuwedzera yegirafu yakawedzera ine yakakwirira yekutanga yekuwedzera tembiricha ndeye 290-300 ℃, uye vhoriyamu yekuwedzera ndeye ≥ 230ml/g.Rudzi urwu rwegirafu rakawedzerwa rinonyanya kushandiswa kudzoreredza moto weinjiniya mapurasitiki uye rabha.Ichi chigadzirwa chakagadzirwa zvakabudirira neHebei Agricultural University uye chakanyorera patent yenyika.

4. Surface yakagadziridzwa graphite
Kana yakawedzerwa graphite inoshandiswa sechinhu chinodzivirira moto, inosanganisira kunyungudika kwegraphite nezvimwe zvikamu.Nekuda kwehupamhi hwemaminerari pamusoro pegraphite, haisi lipophilic kana hydrophilic.Nokudaro, zvakakosha kugadzirisa pamusoro pe graphite kugadzirisa dambudziko rekuenderana pakati pegraphite nezvimwe zvikamu.Vamwe vanhu vakaronga kuchena pamusoro pegraphite, ndiko kuti, kuvhara pamusoro pegraphite nefirimu rakasimba chena.Iri idambudziko rakaoma kugadzirisa.Inosanganisira membrane chemistry kana pamusoro chemistry, iyo inogona kuwanikwa murabhoritari.Pane zvinonetsa mumaindasitiri.Iri rudzi rwechena rinowedzeredzwa graphite rinonyanya kushandiswa semurazvo retardant coating.

5. Kuderera kwekutanga kwekuwedzera tembiricha uye tembiricha yakaderera yakawedzera graphite
Rudzi urwu rwegirafu rakawedzerwa rinotanga kuwedzera pa80-150 ℃, uye vhoriyamu yekuwedzera inosvika 250ml/g pa600 ℃.Zvinetso mukugadzirira kusangana kwegraphite inowedzerwa mamiriro aya ari mu: (1) kusarudza yakakodzera intercalation agent;(2) Kudzora uye kugona mamiriro ekuomesa;(3) Kutsunga unyoro;(4) Mhinduro yematambudziko ekuchengetedza kwezvakatipoteredza.Parizvino, kugadzirira kwepasi-kupisa kunowedzera graphite kuchiri muchikamu chekuedza.
