Graphite ufa uli ndi katundu wambiri, choncho amagwiritsidwa ntchito kwambiri muzitsulo, makina, magetsi, mankhwala, nsalu, chitetezo cha dziko ndi mafakitale ena. Magawo ogwiritsira ntchito ufa wa graphite wachilengedwe ndi ufa wa graphite wochita kupanga ali ndi magawo omwe amalumikizana komanso amasiyana. Mkonzi wotsatira wa Furuite graphite akuwonetsa magawo ogwiritsira ntchito ufa wa graphite ndi ufa wopangira graphite.
1. Makampani opanga zitsulo
M'makampani opangira zitsulo, ufa wa graphite wachilengedwe ungagwiritsidwe ntchito kupanga zinthu zokanira monga njerwa za magnetia-carbon ndi njerwa za aluminiyamu-carbon chifukwa cha kukana kwake kwa okosijeni. Ufa wopangira graphite ukhoza kugwiritsidwa ntchito ngati electrode yopangira zitsulo, koma ma elekitirodi opangidwa ndi ufa wa graphite wachilengedwe ndi ovuta kugwiritsa ntchito m'ng'anjo zamagetsi zopangira zitsulo zokhala ndi zovuta zogwirira ntchito.
2. Makampani opanga makina
M'makina opangira makina, zida za graphite zimagwiritsidwa ntchito ngati zida zosavala komanso zopaka mafuta. The koyamba zopangira pokonzekera expandable graphite ndi mkulu-mpweya flake graphite, ndi zina mankhwala reagents monga anaikira sulfuric acid (pamwamba 98%), wa hydrogen peroxide (pamwamba 28%), potaziyamu permanganate, etc. onse mafakitale-kalasi. reagents. Masitepe ambiri akukonzekera ndi awa: pa kutentha koyenera, njira zosiyanasiyana za hydrogen peroxide solution, flake flake graphite ndi concentrated sulfuric acid zimawonjezedwa m'njira zosiyanasiyana, zomwe zimachitikira kwa nthawi inayake pansi pa kugwedezeka kosalekeza, kenako kutsukidwa ndi madzi mpaka. neutral, ndi centrifuged. Pambuyo pa kutaya madzi m'thupi, amawumitsidwa ndi vacuum pa 60 ° C. Ufa wachilengedwe wa graphite uli ndi mafuta abwino ndipo nthawi zambiri umagwiritsidwa ntchito ngati chowonjezera chamafuta opaka mafuta. Zipangizo zotumizira zing'onozing'ono zowononga zimagwiritsa ntchito mphete za pistoni, mphete zosindikizira ndi zitsulo zopangidwa ndi ufa wa graphite, ndipo sizifunikira kuwonjezera mafuta odzola panthawi yogwira ntchito. Ufa wachilengedwe wa graphite ndi zida zophatikizika za polima zitha kugwiritsidwanso ntchito m'magawo omwe ali pamwambapa, koma kukana kovala sikwabwino ngati kwa ufa wa graphite.
3. Makampani opanga mankhwala
Wopanga graphite ufa ali ndi makhalidwe kukana dzimbiri, matenthedwe madutsidwe wabwino ndi otsika permeability. Amagwiritsidwa ntchito kwambiri mumakampani opanga mankhwala kupanga zosinthira kutentha, akasinja amachitira, nsanja zoyamwitsa, zosefera ndi zida zina. Natural graphite ufa ndi polima utomoni kompositi zipangizo angagwiritsidwenso ntchito m'minda pamwamba, koma matenthedwe madutsidwe ndi kukana dzimbiri si zabwino monga za ufa yokumba graphite.
Ndi chitukuko chosalekeza cha teknoloji yofufuza, chiyembekezo chogwiritsira ntchito ufa wopangira graphite ndi wosayerekezeka. Pakali pano, chitukuko cha zinthu yokumba graphite ndi masoka graphite monga zopangira ndi imodzi mwa njira zofunika kukulitsa ntchito munda wa graphite zachilengedwe. Natural graphite ufa monga wothandiza zopangira wakhala ntchito kupanga ena yokumba graphite ufa, koma chitukuko cha yokumba graphite mankhwala ndi masoka graphite ufa monga waukulu zopangira sikokwanira. Ndi njira yabwino yokwaniritsira cholingachi pomvetsetsa bwino ndikugwiritsa ntchito mawonekedwe ndi mawonekedwe a ufa wa graphite wachilengedwe, ndikutengera njira zoyenera, njira ndi njira zopangira zinthu zopangidwa ndi graphite zokhala ndi mawonekedwe apadera, katundu ndi ntchito.
