Kukulitsa graphite, komwe kumadziwikanso ngati raphite yojambula, ndi njira yopangira makristali yomwe imagwiritsa ntchito njira zosagawika ndi ma carborbote a Nanocanalebon ndege zojambulajambula. Sikuti zimangokhala ndi zojambula zabwino za thupi ndi zokongoletsa monga kutentha kwambiri kukana, kuponderezedwa kwa kutentha, neutron flux, x-ray ndi njira yayitali ya gamma. Ilinso ndi zinthu zapamwamba komanso zamankhwala, zokhala ndi zokongoletsa zochepa, zodzikongoletsera zochepa, zamagetsi komanso zamagetsi, ndi anisotropy. Kuphatikiza apo, chifukwa cha kulumikizana pakati pa zojambulajambula ndi graphite wosanjikiza, graphite wokulitsidwa kumawonetsa zatsopano ndipo zophatikizika sizikhala ndi zojambula zachilengedwe. Okonzanso zojambulajambula zotsatirazi amagawana mawu oyambira a mafayilo a mafakitale ndikugwiritsa ntchito graphite yokulitsidwa:
1. Njira zopangira zomwe zimagwiritsidwa ntchito nthawi zambiri pamakampani
①chemical oxidation
Ubwino: Maxidation yamagetsi amagwiritsidwa ntchito kwambiri komanso njira yokhazikika m'makampani. Chifukwa chake, ili ndi phindu laumboni, ukadaulo wokhwima ndi mtengo wotsika.
Zovuta: Wothandizila kusanja nthawi zambiri amakhala ndi sulfuric acid, omwe amadya ambiri acid. Pali kuwonongeka kwa mpweya wowopsa kwa mpweya pazinthu zopanga, ndipo zotsalira pazogulitsa zimagwirizananso ndi zida za synthesis.
②electrochemication oxidation
Monga makuti makuti makuti mapiration a mankhwala, ndi njira imodzi yodziwika bwino yamagetsi yopukutira graphite.
Ubwino: Palibenso chifukwa chowonjezera oxidal, monga ma acid olimba, ndipo zomwe zikuchitikazo zitha kuwongolera ndi kusintha kwa magawo monga magetsi apano ndi magetsi. Zida zophatikizika ndizosavuta, kuphatikiza kuchuluka kwake ndi kwakukulu, electrolyte sikuyipitsidwa, ndipo imatha kugwiritsidwa ntchito.
Zovuta: Kukhazikika kwa mankhwalawa ndikosavuta kuposa njira zina, zomwe zimafuna zida zapamwamba, ndipo pali zinthu zambiri zomwe zimakhudza mtundu wa malonda. Nthawi zina, voliyumu yowonjezereka ya mankhwalawa imachepetsedwa kwambiri chifukwa cha kuchuluka kwa kutentha kozungulira. Kuphatikiza apo, pali zomwe zimachitika m'mbali mwa mafunde ambiri m'matumba am'madzi, chifukwa ndizovuta kupeza mankhwala oyamba.
2. Mabizinesi akulu opanga ndi mphamvu yopanga
Kupanga kwa zinthu zokutira zokutira kudziko langa kukumbapo kuyambira koyambirira kwa opanga oposa 100, ndi matani apachaka opanga matani 30,000, ndipo malo osungirako msika ndi otsika. Komanso, opanga ambiri amakhala ndi mafilimu omaliza omaliza, omwe samagwiritsidwa ntchito kawirikawiri mu zisindikizo zaokha ndi magetsi a ndege za nyukiliya. Komabe, popanga ukadaulo wapakhomo, kuchuluka kwa zinthu zomaliza kumawonjezeka pang'onopang'ono.
3. Kufuna kwa msika ndi kuneneratu zinthu zosindikizira
Pakadali pano, wokulitsidwa umagwiritsidwa ntchito ngati zida zosindikizira zamagalimoto, monga ma galoni a cylinder a gaskets, zotulutsa ma prephy, etc. Pakadali pano, wokutira graphite wokhala ndi mitate yotsika yomwe yapangidwa, yomwe ingachepetse kwambiri zopanga zokongoletsera zokutira, potero kusintha masbestos pamlingo waukulu ndikufunikira kwambiri. Kumbali inayo, ngati pulasitiki, ziphala za mphira ndi zitsulo zitha kusinthidwa pang'ono, kufunikira kwapanyumba kwa zinthu zokhotakhota zokutira zokutira kwa graphite zidzakhala zokulirapo.
M'mafakitale autoto, aliyense pagalimoto iliyonse yam'madzi, kudya mpweya wambiri komanso mafuta otulutsa mafuta amafunikira pafupifupi graphite, ndipo magalimoto onse 10,000 amafunikira graphite 20. Makampani agalimoto ku China alowa nthawi yayitali. Chifukwa chake, kufunafuna kwanga pachaka kwa zida zokopa zosindikizira kukadali kudalipo kwambiri.
