Nhanganyaya yegraphite flexible inonzwa

Yepamusoro tembiricha graphite inonzwa ine zvimiro zvehuremu huremu, kukanganisa kwakanaka, yakakwira kabhoni yemukati,kukwirira kwekushisa kwepamusoro, hapana volatilization pakupisa kwakanyanya,corrosion resistance, dikithermal conductivityuye yakakwirira chimiro chekuchengetedza.

Chigadzirwa chacho chine zvinotevera zvakanakira: mushure me1800 ~ 2500 ℃ yakakwirira tembiricha kurapwa, tembiricha musiyano pakati chero maviri mapoinzi ainzwa haapfuuri 50 ℃, saka kuita kwechigadzirwa kwakagadzikana. Nekuti inoenderera kugadzirwa, inogona kuve nechokwadi chekufanana kwezvinhu zvinonzwika mune chero hupamhi uye kureba.

Kuenzaniswa necarbon inonzwainorapwa pane yakaderera tembiricha (pazasi 900 ℃), graphite yainzwa yakabatwa pakupisa kwepamusoro (pamusoro pe2200 ℃) ine zvinotevera zvakanakira:

(1) The adsorption yemhute yemvura nemamwe magasi pagraphite ainzwa ari 2 orders of magnitude yakaderera pane iya iri pacarbon inonzwikwa yakabatwa patembiricha yakaderera. Kune akawanda akavharwa midziyo yemidziyo inoda kuvharwa, kuchena kwemhepo ndiyo yakakosha parameter. Nekudaro, nekuda kweiyo yakakwirira adsorption yeyakadzika tembiricha yakabatwa kabhoni inonzwa, zvakaoma kupukuta mudziyo.

(2) Iyo graphite inonzwa ine yakasimba yekupisa oxidation kuramba. Chimiro chekabhoni pasina graphitization imhando yekusagadzikana dhizaini chimiro. Kuvepo kwekukanganisa kwakasiyana kwechimiro kunoita kuti nzvimbo yaro ive yakakura, uye zviri nyore kurwiswa nemaatomu eokisijeni uye oxidized. Iyo latisi yakakwana uye yakarongedzerwa matatu-dimensional kurongeka kwegraphite yakanzwa mushure mekupisa kwekushisa kwakanyanya kunoderedza nzvimbo yekuisa uye kuita kuti zvisave nyore kurwiswa nemaatomu eokisijeni, nekudaro ichiwedzera zvakanyanya iyo antioxidant kugona.

(3) Kuchena kwegraphite kunonzwa kwakakwira, uye kabhoni yemukati inodarika 99.5%. Iyo kabhoni yemukati yekushisa yakadzika yakabatwa kabhoni yakanzwa kazhinji isingasviki 93%, zviri nyore kukonzera kusvibiswa kwezvakatipoteredza muchoto.

Mushoko, tembiricha yepamusoro yakabatwa graphite inonzwa ine zvirinani mhedzisiro uye yakareba sevhisi hupenyu pane yakaderera tembiricha kabhoni yakanzwa.
