Ndeapi maitiro ekuwedzera graphite mushure mekupisa mukuwedzera graphite?

Maitiro ekuwedzera ekuwedzera graphite sheetzvakasiyana kubva kune mamwe maejenti ekuwedzera. Kana ichipisa kune imwe tembiricha, iyo inokwidziridzwa graphite inotanga kuwedzera nekuda kwekuparara kwekomisheni inobatwa mu interlayer lattice, iyo inonzi yekutanga kuwedzera tembiricha. Inowedzera zvakakwana pa1000 ℃ uye inosvika pahuwandu hwepamusoro. Kuwedzera kwevhoriyamu kunogona kusvika kupfuura 200 nguva dzekukosha kwekutanga. Iyo yakawedzerwa graphite inonzi yakawedzera graphite kana graphite worm, iyo inoshanduka kubva kune yepakutanga flake chimiro kuenda kune honye chimiro ine yakaderera density, ichigadzira yakanaka kwazvo yekupisa yekupisa. Yakawedzerwa graphite haisi chete kabhoni sosi mune yekuwedzera sisitimu, asiwo insulating layer. Inogona kubudirirainsulate kupisa. Mumoto, ine hunhu hwekudziya kwakadzika kuburitsa mwero, kudiki kurasikirwa kukuru uye kushoma gasi.

Ndeapi maitiro ekuwedzera graphite mushure mekupisa mukuwedzera graphite?

Hunhu hwekuwedzera graphite

① Kupokana kwakasimba,flexibility, plasticity uye self lubrication;

② Kuramba kwakasimba kune yakakwirira, yakaderera tembiricha,ngurauye mwaranzi;

③ Yakanyanya kusimba maitiro ekudengenyeka;

④ Yakanyanya kusimbaconductivity;

⑤Yakasimba anti-kuchembera uye anti distortion properties.

⑥ Inogona kuramba kunyunguduka uye kupinda kwesimbi dzakasiyana-siyana;

⑦ Haisi chepfu, haina chero carcinogens uye haina kukuvadza kune zvakatipoteredza.

Nzira dzinoverengeka dzekusimudzira graphite yakawedzerwa ndeaya anotevera:

1. Girafu yakawedzerwa nokuda kwezvinangwa zvakakosha

Ongororo dzinoratidza kuti makonye e<em>graphite ane basa rokutora masaisai emagetsi. Iyo yakawedzerwa graphite inofanirwa kuzadzisa zvinotevera zvinodiwa: (1) yakaderera yekutanga yekuwedzera tembiricha uye yakakura yekuwedzera vhoriyamu; (2) Zvimiro zvemakemikari zvakagadzikana, zvakachengetwa kwemakore mashanu, uye kuwedzera kwekuwedzera hakusi kuora; (3) Iyo yepamusoro yegirafu yakawedzerwa haina kwayakarerekera uye haina ngura kune cartridge kesi.

2. Granular yakawedzera graphite

Diki diki rakawedzerwa graphite rinonyanya kureva 300 mesh inokwidziridzwa graphite ine vhoriyamu yekuwedzera ye100ml / g. Ichi chigadzirwa chinonyanya kushandiswa murazvo retardantcoatings, iyo iri kudiwa zvikuru.

3. Yakawedzerwa graphite nepamusoro pekutanga kuwedzera tembiricha

Iyo yekutanga tembiricha yekuwedzera yegraphite yakawedzera neyakakura yekutanga yekuwedzera tembiricha ndeye 290-300 ℃, uye vhoriyamu yekuwedzera iri ≥ 230ml / g. Rudzi urwu rwegirafu rakawedzerwa rinonyanya kushandiswa kudzoreredza moto weinjiniya mapurasitiki uye rabha.

4. Surface yakagadziridzwa graphite

Kana yakawedzerwa graphite inoshandiswa sechinhu chinodzosa moto, inosanganisira kuenderana pakati pegraphite nezvimwe zvinhu. Nekuda kweiyo yakakwira mineralization yegraphite pamusoro, haisi lipophilic kana hydrophilic. Nokudaro, nzvimbo ye graphite inofanira kuchinjwa kugadzirisa dambudziko rekuenderana pakati pegraphite nezvimwe zvikamu. Yakave yakarongedzerwa kuchenesa girafu pamusoro, ndiko kuti, kuvhara girafu yepamusoro nefirimu yakasimba yakachena, iyo idambudziko rakaoma kugadzirisa. Inosanganisira membrane chemistry kana pamusoro chemistry. Murabhoritari inogona kukwanisa kuita kudaro, uye kune matambudziko mukugadzirwa kwemaindasitiri. Iri rudzi rwechena rinowedzeredzwa graphite rinonyanya kushandiswa semurazvo retardant coating.

5. Kuderera kwekutanga kwekuwedzera tembiricha uye tembiricha yakaderera yakawedzera graphite

Rudzi urwu rwegirafu yakawedzerwa inotanga kuwedzera pa80-150 ℃, uye vhoriyamu yekuwedzera inosvika 250ml / g pa600 ℃. Zvinetso mukugadzirira kusangana kwegraphite inowedzerwa mamiriro aya ndeaya: (1) kusarudza yakakodzera intercalation agent; (2) Kudzora uye kugona kwekuomesa mamiriro; (3) Kutsunga unyoro; (4) Mhinduro yematambudziko ekuchengetedza kwezvakatipoteredza.
