Kuchena kwegraphite mbishi zvinhu kunokanganisa maitiro ekuwedzera graphite.

Kana girafu inobatwa nemakemikari, kemikari inogadziriswa inoitwa panguva imwe chete pamucheto wegirafu yakawedzerwa uye nepakati pehupamhi. Kana iyo graphite isina kuchena uye ine tsvina, lattice defects uye dislocations ichaonekwa, zvichikonzera kuwedzera kwenharaunda yemucheto uye kuwedzera kwenzvimbo dzinoshanda, izvo zvichakurumidza kukurumidza kuita. Kunyangwe izvi zvichibatsira pakuumbwa kwemupendero makomboni, zvichakanganisa kuumbwa kweakawedzera graphite intercalation makomponi. Uye iyo latisi yakafukidzwa inoparadzwa, iyo inoita kuti latisi irege kusagadzikana uye isina kurongeka, kuitira kuti kukurumidza uye kudzika kwemakemikari kupararira kune interlayer uye chizvarwa chezvakadzama intercalation compounds zvinodziviswa uye zvishoma, izvo zvinowedzera kukanganisa kuvandudzwa kwedhigirii yekuwedzera. Nokudaro, zvinotarisirwa kuti zvinyorwa zve graphite tsvina zvinofanira kunge zviri mukati mehutano hwakatarwa, kunyanya kusvibiswa kwegranular hakufaniri kuvapo, kana zvisina kudaro zviyero zve graphite zvichagurwa panguva yekutsikirira, izvo zvichaderedza kunaka kwezvinhu zvakaumbwa. Iyo inotevera Furuite graphite mupepeti inosuma kuti kuchena kwegraphite mbishi zvinhu kunokanganisa zvimiro zveakawedzera graphite:

Iyo particle size yegraphite inewo simba guru pakugadzirwa kwegirafu yakawedzerwa. Iyo particle size yakakura, iyo chaiyo nzvimbo idiki, uye nzvimbo inosanganisirwa mukuita kwemakemikari idiki. Pane zvinopesana, kana chidimbu chiri chidiki, nzvimbo yaro chaiyo yakakura, uye nzvimbo yekutora chikamu mukuita kwemakemikari yakakura. Kubva pakuongorora kuoma kwezvinhu zvemakemikari zvinopinda, hazvigoneki kuti zvimedu zvakakura zvichaita kuti zviyero zve graphite zvikonye, ​​uye mikaha pakati pezvikamu ichave yakadzika, saka zvakaoma kuti makemikari apinde muchikamu chimwe nechimwe, uye zvakatonyanya. zvakaoma kupararira mumikaha pakati pezvikamu kuti zvikonzere zvidimbu zvakadzika. Izvi zvine simba guru pakuwedzera dhigirii regirafu rakawedzerwa. Kana ma graphite particles ari akanyanya kunaka, iyo chaiyo nzvimbo ichava yakakura zvikuru, uye kumucheto kwekuita kuchave kwakatonga, izvo zvisingabatsiri pakuumbwa kwezvibatanidza zvinosanganiswa. Naizvozvo, magirafu particles haafaniri kunge akakurisa kana kuti madiki.

Munharaunda imwe chete, muhukama pakati pekusasimba uye chidimbu chekukura kwegirafu rakawedzerwa rakagadzirwa negirafu rine hukuru hwakasiyana-siyana, huduku husina kusimba, huri nani mhedzisiro yegirafu yakawedzerwa. Nekudaro, mukugadzirwa chaiko, zvinoratidzwa kuti saizi yemhando yegraphite inoshandiswa zviri nani kubva -30 mesh kusvika +100 mesh, inova yakanyanya kunaka mhedzisiro.

Simba re graphite particle size inoratidzwawo mukuti iyo particle size yekugadzirwa kwezvigadzirwa haifanire kunge yakafara zvakanyanya, kureva kuti, dhayamita mutsauko pakati pechikamu chikuru uye chidiki diki hachifanirwe kunge chakakurisa, uye kugadzirisa mhedzisiro ichave. zviri nani kana iyo particle size inoumbwa yakafanana. Zvigadzirwa zveFuruite graphite zvese zvinogadzirwa zvechisikigo graphite, uye mhando inodiwa zvakanyanya mukugadzira maitiro. Zvigadzirwa zvegraphite zvakagadziridzwa uye zvakagadzirwa zvakafarirwa nevatengi vatsva nevakuru kwemakore mazhinji, uye iwe unogamuchirwa nguva dzose kubvunza uye kutenga!
