Zotsatira ndi ubwino wa zinthu za graphite

Chifukwa cha zinthu zake zambiri zabwino, graphite imapeza ntchito zambiri m'magawo azitsulo, makina, magetsi, mankhwala, nsalu, ndi mafakitale ena. Imagwira ntchito ngati chinthu chodziletsa ndipo imakhalabe ndi mawonekedwe amtundu wa flake graphite pomwe ikuwonetsa zodzikongoletsera zokha. Graphite ufa umadziwika ndi kukana kwamphamvu kwa asidi, kukana kwa dzimbiri, kulolerana kwa kutentha kwambiri mpaka 3000 ℃ komanso kutsika kwa kutentha mpaka -204 ℃. Kuphatikiza apo, ili ndi mphamvu yopondereza yopitilira 800kg/Cm2 ndipo imawonetsa kukana kwa okosijeni ndi 1% yokha yowonda ikawululidwa ndi mpweya pa 450 ℃. Kuphatikiza apo, ikuwonetsa kuchuluka kwa 15-50% (kachulukidwe 1.1-1.5). Chifukwa chake, zinthu za graphite zimagwiritsidwa ntchito kwambiri muzitsulo, makampani opanga mankhwala, mafakitale a petrochemical, fizikisi yamphamvu kwambiri, zakuthambo, zamagetsi ndi zina zambiri.

Zogulitsa za graphite zili ndi zabwino zambiri:

1, zinthu za graphite zili ndi zotsatsa zabwino.

Kapangidwe ka kaboni kopanda kanthu kamapangitsa kaboni kukhala ndi ma adsorption abwino, chifukwa chake kaboni nthawi zambiri imagwiritsidwa ntchito ngati zinthu zotengera madzi, fungo, zinthu zapoizoni ndi zina zotero. Tachita zoyesera, masiku angapo apitawo thireyi yophika ya graphite imawoneka yoyera kwambiri, koma ikani chotenthetsera chotenthetsera ng'anjo, mudzawona kutsekemera komaliza kwamafuta ndi zinthu zovulaza kumatuluka pang'onopang'ono, koma osadandaula, ndi pepala loyera lazakudya lopukuta lingagwiritsidwe ntchito.

2, zinthu za graphite zimakhala ndi matenthedwe abwino, kutentha kwachangu, kutentha kwa yunifolomu, kupulumutsa mafuta.

Mapepala ophika ndi mapeni opangidwa ndi graphite amatenthedwa mofulumira, ndipo chakudya chowotcha chimatenthedwa mofanana, chophikidwa kuchokera mkati, ndipo nthawi yotentha imakhala yochepa, osati kukoma kokha, komanso zakudya zoyambirira za chakudya zimatha kutsekedwa. . Tachita zoyeserera, pomwe poto ya graphite imagwiritsidwa ntchito pakuwotcha, chophika cholowera chimawotcha pamoto poyambira, ndipo chimatha kutenthedwa mumasekondi 20-30 okha, ndipo chakudya chikayamba, chimatha kuseweredwa pa moto wawung'ono, womwe ungapulumutse mphamvu.

3, zinthu za graphite zimakhala ndi kukhazikika kwamankhwala komanso kukana dzimbiri.

Graphite imakhala ndi kukhazikika kwamankhwala bwino kutentha kwa chipinda ndipo sikuwukiridwa ndi asidi amphamvu, maziko amphamvu ndi zosungunulira za organic. Chifukwa chake, ngakhale kugwiritsidwa ntchito kwanthawi yayitali kwa zinthu za graphite ndikotayika pang'ono, bola kumapukutidwa ngati kwatsopano.

Zopangira 4 za graphite zimakhala ndi anti-oxidation yamphamvu komanso yochepetsera.

Zamgulu, makamaka graphite matiresi Kutentha akhoza kutulutsa ayoni mpweya zoipa, kupanga zinthu zozungulira yogwira, kusunga thanzi la munthu, mogwira kuteteza ukalamba, kupanga khungu wodzaza ndi luster ndi elasticity.

5, graphite mankhwala chilengedwe thanzi, palibe kuipitsidwa radioactive, kutentha kukana.

Mpweya ukhoza kukhala graphite patatha masiku osachepera khumi ndi mausiku a graphitization m'malo otentha kwambiri a madigiri 2000-3300, kotero kuti zinthu zoopsa ndi zovulaza za graphite zatulutsidwa kale ndipo zimakhala zokhazikika mkati mwa madigiri osachepera 2000.

Pa nthawi yomweyo, mankhwala graphite chifukwa cha dongosolo lake lapadera, ndi mkulu kutentha kukana, matenthedwe kukana mantha, madutsidwe magetsi, lubrication, kukhazikika mankhwala ndi plasticity ndi makhalidwe ena ambiri, wakhala gwero lofunika kwambiri pa chitukuko cha makampani ankhondo ndi amakono. ndi ukadaulo wapamwamba, watsopano komanso wakuthwa, zinthu za graphite, monga mphete za graphite, mabwato a graphite amagwiritsidwa ntchito kwambiri. Akatswiri apadziko lonse lapansi aneneratu kuti "zaka za zana la 20 ndi zaka za silicon, zaka za zana la 21 zidzakhala zaka za carbon."

Monga chinthu chofunikira kwambiri chosagwiritsa ntchito zitsulo, makampani opanga ma graphite adzakhazikitsidwa kasamalidwe ka mwayi. Ndi kukhazikitsidwa kwa njira yopezera, graphite, mankhwala a graphite, adzakhala wina pambuyo pa dziko losowa, mankhwala a fluorine, phosphorous mankhwala, makampani otsogolera m'munda uno adzalowa gawo latsopano lachitukuko.
