  • Phofo ea graphite

Tlhaloso e Khutšoanyane:

Phofo ea graphite ke ntho ea bohlokoa ea inorganic nonmetallic material, e leng phofo e ntle e fumanoang ka pyrolysis kapa carbonization ea carbon ka mocheso o phahameng.Phofo ea Graphite e na le lisebelisoa tse ikhethang tsa lik'hemik'hale, tsa 'mele le tsa mochini, ka hona e sebelisoa haholo libakeng tse ngata, joalo ka lisebelisoa tsa elektronike, lik'hemik'hale, metallurgy, ho etsa borashe, ho roala, thepa ea mohaho le liindasteri tse ling.

Sehlahisoa sa tlhaho

Phofo ea graphite ke mofuta oa phofo e ntle e entsoeng ka carbon ka mor'a pyrolysis e phahameng ea mocheso kapa carbonization, 'me karolo ea eona e kholo ke carbon.Phofo ea graphite e na le sebopeho se ikhethang sa lera, se bohlooho bo botšo kapa botšo bo bobebe.Boima ba eona ba molek'hule ke 12.011.

Litšobotsi tsa phofo ea graphite li ka akaretsoa ka tsela e latelang:

1. High conductivity le mocheso oa mocheso: phofo ea graphite ke thepa e ntle ea ho khanna le ea mocheso, e nang le mocheso o phahameng oa mocheso le conductivity.Sena se bakoa haholo ke tlhophiso e thata le sebopeho se layered sa liathomo tsa k'habone ka graphite, e etsang hore ho be bonolo hore lielektrone le mocheso li tsamaee.

2. Ho se sebetse hantle ha lik'hemik'hale: phofo ea graphite e na le botsitso bo botle ba lik'hemik'hale le ho se sebetse tlas'a maemo a tloaelehileng, 'me ha e sebetsane le lintho tse ngata.Hape ke ka lebaka leo phofo ea graphite e sebelisoang haholo masimong a lisebelisoa tsa elektronike le lik'hemik'hale, tšireletso ea mocheso o phahameng oa mocheso, joalo-joalo.

3. E na le matla a itseng a mechine: ha e bapisoa le lisebelisoa tse ling tsa nano-material, phofo ea graphite e na le ts'ebetso e phahameng ea ho hanyetsa, extrusion resistance le crack resistance, e ka ntlafatsang thepa ea mechine ea thepa ho isa tekanyong e itseng.

Ho lokisetsa lihlahisoa

Mekhoa ea ho lokisa phofo ea graphite e fapane, 'me mekhoa e tloaelehileng ke e latelang:

1. Pyrolysis ka mocheso o phahameng: mocheso oa tlhaho oa graphite kapa kristale ea graphite e entsoeng ka lik'hemik'hale ho mocheso o phahameng (ka holimo ho 2000 ℃) ho e senya hore e be phofo ea graphite.

2. Mokhoa o phahameng oa mocheso oa carbonization: phofo ea graphite e fumanoa ka lik'hemik'hale tsa lik'hemik'hale tsa graphite tse nang le lisebelisoa tse nang le lisebelisoa tse nang le lesela le tšoanang le graphite.Ho latela lisebelisoa tse fapaneng tse tala, e ka aroloa ka mekhoa e fapaneng ea ho itokisa, joalo ka mouoane oa lik'hemik'hale tsa mouoane, pyrolysis le carbonization.

3. Mokhoa oa mechine: ka ts'ebetso ea ho sila le ho hlahloba mechine, lisebelisoa tsa tlhaho tsa graphite kapa li-synthetic graphite li sebelisoa ho fumana phofo ea graphite.

Mekhoa e fapaneng ea ho itokisa e na le litlamorao tse fapaneng ho boleng, bohloeki le morphology ea phofo ea graphite.Litšebelisong tse sebetsang, mekhoa e loketseng ea ho itokisa e hloka ho khethoa ho latela litlhoko tse fapaneng.

Sesebelisoa sa sehlahisoa

1. Lisebelisoa tsa elektronike le tsa lik'hemik'hale: phofo ea graphite e ka lokisoa ka li-composite tsa polymer conductive le thermal conductive, tse sebelisoang lisebelisoa tsa elektronike, libeteri, li-inks tsa conductive le masimo a mang.Ka mohlala, ka lisebelisoa tsa electrode, phofo ea graphite e ka eketsa conductivity ea thepa, ho ntlafatsa ts'ebetso ea electrochemical ea electrode, le ho lelefatsa bophelo ba tšebeletso ea betri.

2. Lisebelisoa tsa ho roala: phofo ea graphite e ka sebelisoa bakeng sa ho lokisa liphahlo tse fapa-fapaneng, tse kang anti-corrosion coating, mocheso oa conductivity oa mocheso, tšireletso ea motlakase, joalo-joalo Libakeng tsa likoloi, lifofane, kaho, joalo-joalo. ka phofo ea graphite e ka ntlafatsa ho hanyetsa ha ultraviolet le ho hanyetsa kutu ea thepa.

3. Catalyst: Phofo ea graphite e ka sebelisoa bakeng sa ho lokisoa ha li-catalyst, 'me e sebelisoa haholo ho manyolo a tlhaho, tlhahiso ea lik'hemik'hale le masimo a mang.Ka mohlala, ka hydrogenation ea oli ea limela, phofo ea graphite ka mor'a phekolo e ka sebelisoa e le mohloli oa ho ntlafatsa mokhoa oa ho khetha le ho hlahisa lihlahisoa.

4. Lisebelisoa tsa Ceramic: Ha ho etsoa lisebelisoa tsa ceramic, phofo ea graphite e ka ntlafatsa matla a eona a mochine le thepa e meng ka ho matlafatsa phello.Haholo-holo ka li-cermets le li-ceramics tsa porous, phofo ea graphite e sebelisoa haholo.
