Ufa wa graphite ndi chinthu chogwiritsidwa ntchito mosiyanasiyana kwambiri chomwe chili chofunikira kwambiri m'mafakitale osiyanasiyana chifukwa cha mankhwala ake apadera komanso mawonekedwe ake. Kugwiritsa ntchito kwake kumayambira pa mafuta odzola ndi zitsulo mpaka kusungira mphamvu ndi kupanga zinthu zapamwamba. Ufa wa graphite wabwino kwambiri umatsimikizira kuti zinthu zikuyenda bwino, kukhazikika, komanso kulimba m'mafakitale. Nkhaniyi ikufotokoza makhalidwe ofunikira a ufa wa graphite wabwino kwambiri, ntchito zake zazikulu m'mafakitale, ndi malangizo osankha mtundu woyenera pazosowa zinazake.

KumvetsetsaUfa wa Graphite

Tanthauzo ndi Katundu

Ufa wa graphite ndi mtundu wa kaboni wopangidwa mwachilengedwe kapena wopangidwa mwaluso, womwe umadziwika ndi kapangidwe kake ka mapepala a graphene. Gawo lililonse limakhala ndi maatomu a kaboni okonzedwa mu lattice ya hexagonal, zomwe zimapatsa zinthuzo zinthuzo zinthu zapadera monga kutentha kwambiri, mphamvu zamagetsi, kusakhala ndi mpweya wabwino, komanso mafuta. Ufa wa graphite si wachitsulo, umakhala wolimba, komanso umalimbana ndi kutentha kwambiri, zomwe zimapangitsa kuti ukhale woyenera malo ofunikira mafakitale.

Ufa wa graphite umagawidwa m'magulu osiyanasiyana kutengera kuyera, kukula kwa tinthu, ndi momwe tikufunira kugwiritsa ntchito. Graphite ya mafakitale ikhoza kukhala yoyera kuyambira pamlingo wamba (~97%) mpaka pamlingo woyera kwambiri (≥99.9%), pomwe kukula kwa tinthu kumatha kusiyana kuyambira pa coarse mpaka submicron, kutengera momwe timagwiritsidwira ntchito.

Makhalidwe Ofunika a Ufa Wapamwamba wa Graphite

Ufa wa graphite wapamwamba kwambiri umapereka zinthu zingapo zofunika zomwe zimasiyanitsa ndi zinthu zotsika mtengo:

●Kuyera kwambiri- Kawirikawiri pamwamba pa 99%, kuchepetsa zinyalala zomwe zingakhudze magwiridwe antchito mu ntchito zofunika kwambiri.

●Kugawa kwa tinthu tating'ono ...- Zimathandiza kuti zinthu zophatikizika, mafuta, kapena ma anode a batri azigwira ntchito bwino komanso kuti zinthuzo zizigwira ntchito bwino nthawi zonse.

●Ubwino wokhazikika komanso mawonekedwe a tinthu tating'onoting'ono- Zimathandiza kuti zotsatira zake zikhale zodalirika komanso zimachepetsa kusiyana kwa njira.

●Kutentha kwabwino kwambiri- Zimathandiza kuti kutentha kusamayende bwino komanso kuti mphamvu zizigwiritsidwa ntchito bwino nthawi yotentha kwambiri.

●Phulusa lochepa- Zimaletsa kuipitsidwa ndi zinthu zopangidwa ndi zitsulo kapena mankhwala.

●Mafuta abwino opaka- Amachepetsa kukangana ndi kuwonongeka kwa makina ndi zinthu zoyenda.

Kugwiritsa Ntchito Ufa Wapamwamba wa Graphite mu Mafakitale

1. Mafuta odzola

Ufa wa graphite umagwiritsidwa ntchito kwambiri ngati mafuta olimba pomwe mafuta amadzimadzi achikhalidwe amatha kulephera. Kuchuluka kwake kochepa kwa kupsinjika kumachepetsa kuwonongeka ndi kung'ambika pamalo, kukulitsa moyo wa zinthuzo ndikuwonjezera magwiridwe antchito. Ufa wa graphite umagwira ntchito bwino kwambiri m'malo otentha kwambiri kapena otayira mpweya, komwe mafuta kapena mafuta amatha kuwonongeka.

Ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo:

● Zigawo zamagalimoto monga magiya, mabuleki, ndi ma clutch assemblies.

● Makina olondola, kuphatikizapo zida zamakina ndi zida zamafakitale.

● Maberiya, zotsekera, ndi makina otsetsereka m'mauvuni otentha kwambiri kapena makina osindikizira.

Ufa wa grafiti ukhoza kusakanizidwa ndi mafuta ndi mafuta kapena kugwiritsidwa ntchito mwachindunji ngati mafuta ouma pamalo omwe ali ndi mikhalidwe yovuta kwambiri.

2. Kusungirako Mphamvu

Ufa wa graphite umagwira ntchito yofunika kwambiri pakusunga mphamvu, makamaka popanga batire ya lithiamu-ion. Umagwiritsidwa ntchito kwambiri ngati gawo lalikulu la zinthu za anode. Ufa wa graphite wapamwamba kwambiri umathandizira:

● Kuwongolera bwino kwa magetsi kuti pakhale mphamvu yotulutsa mphamvu komanso mphamvu yogwiritsira ntchito magetsi.

● Kuyenda bwino kwa njinga, kuchepetsa kutayika kwa mphamvu pakapita nthawi.

● Kuchuluka kwa mphamvu komanso nthawi yayitali ya batri, zomwe ndizofunikira kwambiri pa zamagetsi, magalimoto amagetsi, ndi makina osungira mphamvu zongowonjezwdwanso.

Ufa wa graphite woyera kwambiri wokhala ndi tinthu tating'onoting'ono ta submicron ndi wabwino kwambiri pamabatire ogwira ntchito bwino chifukwa cha kufanana bwino komanso kusasokoneza pang'ono kwa zinthu.

3. Zipangizo Zachitsulo ndi Zosapanga Chitsulo

Mu metallurgy, ufa wa graphite umagwiritsidwa ntchito kwambiri ngati zinthu zopangira zoumba, nkhungu, ma electrode, ndi zinthu zina zotsutsa. Kusungunuka kwake kwakukulu, kukhazikika kwa kutentha, komanso kusagwira ntchito kwa mankhwala kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zokhudzana ndi zitsulo zosungunuka kapena malo owononga.

Ufa wa grafiti umagwiritsidwa ntchito kwambiri mu:

● Kupanga zitsulo ndi mafakitale opangira zitsulo, komwe kumathandizira kulamulira mpweya wa kaboni ndi kuyang'anira kutentha.

● Kupanga zitsulo zopanda chitsulo, monga aluminiyamu kapena mkuwa.

● Kupanga zinthu zotsitsimula, zomwe zimapangitsa kuti nkhungu ndi zophimba zikhale zolimba komanso zoteteza kutentha.

Kukhazikika kwa zinthuzo kumatsimikizira kuti njira zopangira zitsulo zimakhalabe zogwira mtima pamene zimachepetsa kuipitsidwa kapena zolakwika mu zinthu zomaliza.

4. Ntchito Zina Zamakampani

Kupatula mafuta odzola, kusungira mphamvu, ndi zitsulo, ufa wa graphite wapamwamba kwambiri umagwiritsidwa ntchito m'magawo osiyanasiyana amafakitale, kuphatikizapo:

●Zophimba zoyendetsa– Ufa wa grafiti umagwiritsidwa ntchito mu utoto, inki, ndi ma polima oyendetsera mpweya kuti ateteze zinthu zosasinthasintha komanso zamagetsi.

●Zisindikizo ndi ma gasket- Kusagwira ntchito kwa mankhwala ake komanso kukhazikika kwa kutentha kumapangitsa kuti ikhale yoyenera kugwiritsa ntchito njira zotsekera bwino kwambiri.

●Zosakaniza ndi zinthu zokangana- Ufa wa grafiti umathandiza kuti zinthu zisawonongeke, kutentha kumawongoleredwa, komanso kuti makina azigwira ntchito bwino m'makina opangidwa ndi akatswiri komanso ma brake pads.

Kuyerekeza kwa Deta ya Graphite Powder Grades

Deta iyi ikuwonetsa momwe ufa wa graphite woyera kwambiri komanso wocheperako wa tinthu tating'onoting'ono umaperekera mphamvu yabwino kwambiri ya kutentha ndi magetsi, zomwe ndizofunikira kwambiri pamafakitale apamwamba.

Mafunso Ofunsidwa Kawirikawiri

Q: Kodi ubwino wa ufa wa graphite wapamwamba kwambiri ndi wotani pa ntchito zamafakitale?
A: Ufa wa graphite woyeretsedwa kwambiri umapereka mphamvu yoyendetsera kutentha, magwiridwe antchito amagetsi, mafuta odzola, komanso kukhazikika kwa njira, zomwe zimapangitsa kuti makina azigwira bwino ntchito komanso kulimba, makina osungira mphamvu, komanso ntchito zachitsulo zigwire ntchito bwino.

Q: Kodi ufa wa graphite umasiyana bwanji ndi graphite flakes?
Yankho: Ufa wa grafiti umakhala ndi tinthu tating'onoting'ono tophwanyika bwino, pomwe tinthu ta grafiti ndi tating'onoting'ono komanso tofanana ndi mbale. Ufa umakondedwa kuti ugwiritsidwe ntchito pofunikira kufalikira kofanana, kupangika kwa anode molondola, kapena kukhudzana ndi malo okwera.

Q: Kodi ufa wa graphite ungagwiritsidwe ntchito m'malo otentha kwambiri?
A: Inde, ufa wa graphite ndi wokhazikika pa kutentha, ndipo kutentha kwake kumakhala kochepa, zomwe zimapangitsa kuti ukhale woyenera kwambiri pa ntchito zotentha kwambiri monga uvuni, nkhungu, ndi makina opaka mafuta ogwirira ntchito kwambiri.

Mapeto

Ufa wa graphite wabwino kwambiri ndi chinthu chogwiritsidwa ntchito m'mafakitale osiyanasiyana. Kapangidwe kake—kutentha, mafuta, kukhazikika kwa mankhwala, ndi mphamvu zamagetsi—kumapangitsa kuti ikhale yofunika kwambiri pakudzola mafuta, kusunga mphamvu, zitsulo, zinthu zophatikizika, ndi ntchito zina zambiri.

Posankha ufa wa graphite, ndikofunikira kuganizira zachiyero, kukula kwa tinthu tating'onoting'ono, katundu wa kutentha, ndi zofunikira pakugwiritsa ntchitoKusankha giredi yoyenera kumatsimikizira kuti zinthu zopangidwa ndi mafakitale zimagwira ntchito bwino, zimagwira ntchito bwino, komanso kuti zinthu zopangidwa ndi mafakitale zikhale zolimba nthawi yayitali.

Malangizo Osankha Zogulitsa

Kuti mupeze phindu lalikulu la ufa wa graphite m'mafakitale:

● Sankhani milingo yoyera yoposa 99% kuti mugwire bwino ntchito.
● Sankhani kukula kwa tinthu tomwe timagwirizana ndi ntchitoyo.
● Ganizirani za mphamvu ya kutentha ndi mafuta odzola pa ntchito yotentha kwambiri kapena yamphamvu.
● Onetsetsani kuti zinthu zonse zili bwino nthawi zonse kuti muchepetse kusiyana kwa zinthu komanso kuti mupitirize kugwira ntchito bwino.

Mwa kusankha ufa wapamwamba wa graphite wokonzedwa bwino kuti ugwirizane ndi zosowa za mafakitale, opanga amatha kuchita bwino kwambiri, kulimba, komanso kugwira ntchito bwino, zomwe zimapangitsa kuti ikhale gawo lofunika kwambiri pa ntchito zamakono zamafakitale.
