Kugwiritsa ntchito ufa wa graphite

Graphite ingagwiritsidwe ntchito ngati pensulo, utoto, chopukutira, pambuyo pokonza mwapadera, ikhoza kupangidwa ndi zipangizo zosiyanasiyana zapadera, zomwe zimagwiritsidwa ntchito m'magawo okhudzana ndi mafakitale. Ndiye kodi kugwiritsa ntchito ufa wa graphite ndi kotani? Nayi kusanthula kwanu.

Ufa wa grafiti uli ndi kukhazikika kwabwino kwa mankhwala. Toner ya miyala ikakonzedwa mwapadera, imakhala ndi kukana dzimbiri, kutentha bwino, kutsika kwa mpweya, imagwiritsidwa ntchito kwambiri popanga chosinthira kutentha, thanki yoyatsira, condenser, nsanja yoyaka, nsanja yoyamwa, choziziritsira, chotenthetsera, chosefera, zida zopopera. Imagwiritsidwa ntchito kwambiri mu petrochemical, hydrometallurgy, acid ndi alkali, ulusi wopangira, mapepala ndi mafakitale ena, imatha kusunga zitsulo zambiri.

Pa kuponyera, kuponyera kwa aluminiyamu, kuumbidwa ndi zipangizo zachitsulo zotentha kwambiri: chifukwa cha kuchuluka kwa kutentha kwa graphite, kutentha kwake kumakhala kochepa, ndipo kusintha kwa kutentha kumatha kuchitika, kungagwiritsidwe ntchito ngati nkhungu yagalasi, pogwiritsa ntchito graphite yakuda, kukula kwake kosalala komanso zipatso zambiri, palibe kukonza kapena kukonza pang'ono komwe kungagwiritsidwe ntchito, kuti asunge zitsulo zambiri. Kupanga simenti carbide powder metallurgy process, nthawi zambiri kumapangidwa kuchokera ku zinthu za graphite, kumapakidwa ndi zombo za porcelain. Zitsulo zokulira za kristalo, monga monocrystalline silicon, zombo zoyeretsera zachigawo, zomangira zolumikizira, zotenthetsera zoyambitsa, ndi zina zotero, zimakonzedwa kuchokera ku graphite yoyera kwambiri. Kuphatikiza apo, graphite ingagwiritsidwenso ntchito ngati vacuum smelting graphite insulation board ndi base, chubu cha ng'anjo cholimba kutentha, bala, mbale, latisi ndi zina.

Graphite ingathenso kuletsa kukula kwa boiler, mayeso oyenerera akuwonetsa kuti kuwonjezera ufa wa graphite m'madzi (pafupifupi magalamu 4-5 pa tani imodzi ya madzi) kungalepheretse kukula kwa pamwamba pa boiler. Kuphatikiza apo, graphite ingagwiritsidwe ntchito m'ma chimney achitsulo, madenga, milatho ndi mapaipi.

Kuphatikiza apo, graphite kapena galasi ndi pepala mu mafakitale opepuka opopera ndi dzimbiri, ndi chinthu chopangidwa ndi pensulo, inki, utoto wakuda, inki ndi diamondi yopangidwa, diamondi yofunikira kwambiri popanga zinthu zopangira. Ndi chinthu chabwino kwambiri chosunga mphamvu komanso choteteza chilengedwe, United States yakhala ikugwiritsa ntchito ngati batire yagalimoto. Ndi chitukuko cha sayansi ndi ukadaulo wamakono ndi mafakitale, kugwiritsa ntchito graphite kukupitilira kukula, kwakhala chinthu chofunikira kwambiri pakupanga zinthu zatsopano, ndipo kwakhala malo ofunikira kwambiri pazachuma cha dziko.

Amagwiritsidwa ntchito m'makampani opanga mphamvu za atomiki ndi makampani oteteza dziko: ufa wa graphite uli ndi positron yabwino ya neutron yomwe imagwiritsidwa ntchito mu ma reactor a atomiki, uranium graphite reactor imagwiritsidwa ntchito kwambiri mu atomic reactor. Popeza mphamvu yomwe imagwiritsidwa ntchito ngati zinthu zochepetsera mphamvu ya nyukiliya, iyenera kukhala ndi malo osungunuka kwambiri, kukhazikika komanso kukana dzimbiri, ndipo ufa wa graphite ukhoza kukwaniritsa zofunikira zomwe zili pamwambapa. Graphite yomwe imagwiritsidwa ntchito mu ma reactor a atomiki ndi yoyera kwambiri kotero kuti zonyansa siziyenera kupitirira magawo makumi pa miliyoni. Makamaka, kuchuluka kwa polone kuyenera kukhala kochepera 0.5PPM. Mu makampani oteteza, ufa wa graphite umagwiritsidwanso ntchito popanga ma nozzles a maroketi olimba, ma cones a mphuno ya ma rocket, zida zogwiritsira ntchito zida zoyendera mumlengalenga, kutchinjiriza kutentha, ndi zida zoteteza ku radiation.
