Njira zodziwika bwino zoyeretsera graphite ya flake ndi zabwino ndi zoyipa zake

Graphite yopyapyalaimagwiritsidwa ntchito kwambiri m'mafakitale, koma kufunika kwa graphite ya flake kumasiyana m'mafakitale osiyanasiyana, kotero graphite ya flake imafuna njira zosiyanasiyana zoyeretsera. Mkonzi wotsatira wa graphite wa Furuite adzafotokoza njira zoyeretseragraphite yopyapyalaali ndi:

1. Njira ya hydrofluoric acid.
Ubwino waukulu wa njira ya hydrofluoric acid ndi kuchotsa zinyalala zambiri, kuchuluka kwa zinthu zomwe zimagwiritsidwa ntchito, kusakhudza kwambiri magwiridwe antchito a zinthu za graphite komanso kugwiritsa ntchito mphamvu zochepa. Choyipa chake ndichakuti hydrofluoric acid ndi yoopsa kwambiri komanso yowononga, ndipo njira zodzitetezera ziyenera kutengedwa popanga zinthu. Zofunikira za zida zimapangitsanso kuti mtengo ukwere. Kuphatikiza apo, madzi otayidwa omwe amapangidwa ndi njira ya hydrofluoric acid ndi oopsa kwambiri komanso owononga, ndipo amafunika kukonzedwa mosamala asanatulutsidwe. Ndalama zomwe zimagwiritsidwa ntchito poteteza chilengedwe zimachepetsanso kwambiri ubwino wa njira ya hydrofluoric acid yotsika mtengo.
2, njira yoyambira yoyeretsera asidi.
Kuchuluka kwa mpweya mu graphite woyeretsedwa ndi njira ya alkaline acid kumatha kufika pa 99%, zomwe zimakhala ndi mawonekedwe otsika a ndalama zogwiritsidwa ntchito kamodzi kokha, mtundu wapamwamba wa zinthu komanso kusinthasintha kwamphamvu kwa njira. Kuphatikiza apo, ili ndi ubwino wa zida zanthawi zonse komanso kusinthasintha kwakukulu. Njira yoyambira ya asidi ndiyo njira yomwe imagwiritsidwa ntchito kwambiri ku China. Zoyipa zake ndi kugwiritsa ntchito mphamvu zambiri, nthawi yayitali yochitira zinthu, kutayika kwakukulu kwa graphite komanso kuipitsa madzi otayira kwambiri.
3. Njira yokazinga ndi chlorine.
Kutentha kochepa kokazinga ndi kugwiritsa ntchito pang'ono chlorine mu njira yokazinga ya chlorination kumachepetsa kwambiri mtengo wopangiragraphiteNthawi yomweyo, kuchuluka kwa mpweya wa graphite m'zinthu zopangidwa ndi graphite ndikofanana ndi kwa hydrofluoric acid, ndipo kuchuluka kwa mpweya wobwezeretsedwa pogwiritsa ntchito njira yokazinga chlorination ndikokwera. Komabe, chifukwa chlorine ndi poizoni komanso wowononga, imafuna kugwiritsa ntchito zida zambiri ndipo imafunika kutsekedwa mwamphamvu, ndipo mpweya wam'mbuyo uyenera kukonzedwa bwino, kotero mpaka pamlingo wina, umachepetsa kufalikira kwake ndi kugwiritsidwa ntchito kwake.
4. Njira yotentha kwambiri.
Ubwino waukulu wa njira yotenthetsera kwambiri ndi wakuti mpweya wochuluka mu chinthucho ndi wokwera kwambiri, womwe ungafike pamwamba pa 99.995%. Choyipa chake ndichakuti ng'anjo yotenthetsera kwambiri iyenera kupangidwa mwapadera, zida zake ndi zodula, ndipo pali ndalama zambiri zowonjezera. Kuphatikiza apo, kugwiritsa ntchito mphamvu kumakhala kwakukulu, ndipo ndalama zambiri zamagetsi zimawonjezera mtengo wopangira. Kuphatikiza apo, mikhalidwe yovuta yopangira imapangitsanso kuti kugwiritsa ntchito njira iyi kukhale kochepa kwambiri. Pokhapokha pa chitetezo cha dziko, ndege ndi zochitika zina zomwe zimakhala ndi zofunikira zapadera pa kuyera kwa zinthu za graphite, njira iyi imaganiziridwa popanga zinthu zazing'ono za graphite.graphite, ndipo sizingatchulidwe m'mafakitale.
