Zotsatira ndi ubwino wa zinthu za graphite

Chifukwa cha makhalidwe ake ambiri abwino, graphite imagwiritsidwa ntchito kwambiri m'magawo a zitsulo, makina, zamagetsi, mankhwala, nsalu, ndi mafakitale ena. Imagwira ntchito ngati chinthu chotsutsa ndipo imasunga mawonekedwe oyambirira a graphite ya flake pomwe ikuwonetsa mphamvu zodzipaka zokha. Ufa wa graphite umadziwika ndi kukana asidi kwambiri, kukana dzimbiri, kupirira kutentha kwambiri mpaka 3000℃ komanso kupirira kutentha kochepa mpaka -204℃. Kuphatikiza apo, imakhala ndi mphamvu yopondereza yoposa 800kg/Cm2 ndipo imawonetsa kukana kwa okosijeni ndi 1% yokha yochepetsa thupi ikayikidwa mumlengalenga pa 450℃. Kuphatikiza apo, imakhala ndi liwiro lobwerera la 15-50% (kuchuluka kwa 1.1-1.5). Chifukwa chake, zinthu za graphite zimagwiritsidwa ntchito kwambiri mu metallurgy, makampani opanga mankhwala, makampani opanga mafuta, fizikisi yamphamvu kwambiri, ndege, zamagetsi ndi zina zambiri.

Zogulitsa za graphite zokha zili ndi ubwino waukulu kwambiri:

1, zinthu za graphite zimakhala ndi mayamwidwe abwino.

Kapangidwe ka mpweya wopanda kanthu kamapangitsa kuti mpweya ukhale ndi madzi abwino, kotero mpweya nthawi zambiri umagwiritsidwa ntchito ngati chinthu choyamwa madzi, fungo, zinthu zoopsa ndi zina zotero. Tachita zoyeserera, masiku angapo apitawo thireyi yophikira ya graphite yogwiritsidwa ntchito pa barbecue imawoneka yoyera kwambiri, koma ikayikidwa pa uvuni wotenthetsera, mudzawona kuti mafuta ndi zinthu zoopsa zidzatuluka pang'onopang'ono, koma musadandaule, ndi pepala loyera lopukutira lingagwiritsidwe ntchito.

2, zinthu za graphite zimakhala ndi ma conductivity abwino a kutentha, kutentha mwachangu, kutentha kofanana, komanso kusunga mafuta.

Mapepala ophikira ndi miphika yopangidwa ndi graphite amatenthedwa mwachangu, ndipo chakudya chotenthedwa chimatenthedwa mofanana, chophikidwa kuchokera mkati kupita kunja, ndipo nthawi yotenthetsera ndi yochepa, sikuti kukoma kokha kumakhala koyera, komanso michere yoyambirira ya chakudya imatha kutsekedwa. Tachita zoyeserera, pamene poto ya graphite grill imagwiritsidwa ntchito kuwotcha, chophikira choyambira chimayatsa moto poyamba, ndipo chimatha kutenthedwa mu masekondi 20-30 okha, ndipo chakudya chikayatsidwa, chimatha kuseweredwa pamoto wochepa, womwe ungasunge mphamvu.

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

Graphite imakhala ndi mphamvu yokhazikika ya mankhwala kutentha kwa chipinda ndipo siigwidwa ndi asidi wamphamvu, maziko olimba ndi zosungunulira zachilengedwe. Chifukwa chake, ngakhale kugwiritsidwa ntchito kwa nthawi yayitali kwa zinthu za graphite sikutayika kwenikweni, bola ngati yachotsedwa ngati yatsopano.

Zinthu 4 za graphite zimakhala ndi mphamvu yolimbana ndi okosijeni komanso kuchepetsa mphamvu.

Zinthu monga kutentha kwa matiresi a graphite zimatha kupanga ma ayoni oipa a okosijeni, kupangitsa zinthu zozungulira kukhala zogwira ntchito, kusunga thanzi la anthu, kuteteza kukalamba bwino, kupangitsa khungu kukhala lowala komanso losasinthasintha.

5, zinthu za graphite, zachilengedwe, palibe kuipitsa kwa radioactive, komanso kutentha kwambiri.

Mpweya wa kaboni ukhoza kukhala graphite patatha masiku osachepera khumi ndi awiri ndi usiku umodzi utasinthidwa kukhala graphite pamalo otentha kwambiri a madigiri 2000-3300, kotero zinthu zoopsa komanso zovulaza mu graphite zakhala zikutulutsidwa kwa nthawi yayitali ndipo zimakhala zokhazikika mkati mwa madigiri osachepera 2000.

Nthawi yomweyo, zinthu za graphite chifukwa cha kapangidwe kake kapadera, kolimba kutentha kwambiri, kukana kutentha, kuyendetsa magetsi, mafuta, kukhazikika kwa mankhwala ndi pulasitiki ndi zina zambiri, zakhala chuma chofunikira kwambiri pakukula kwa makampani ankhondo ndi amakono ndipo ukadaulo wapamwamba, watsopano komanso wakuthwa, zinthu za graphite, monga mphete za graphite, maboti a graphite zimagwiritsidwa ntchito kwambiri. Akatswiri apadziko lonse lapansi aneneratu kuti "zaka za m'ma 20 ndi zaka za silicon, zaka za m'ma 2000 zidzakhala zaka za carbon."

Monga chinthu chofunikira kwambiri cha mchere chosakhala chachitsulo, makampani opanga graphite adzakhazikitsidwa kuti azitha kugwiritsa ntchito njira zopezera zinthu. Pogwiritsa ntchito njira yopezera zinthu, graphite, zinthu za graphite, zidzakhala makampani ena otsogola m'munda uno, mankhwala a fluorine, mankhwala a phosphorous, ndi makampani otsogola m'munda uno adzalowa mu gawo latsopano la chitukuko.
