Graphite ufa ndi golide m'munda wamafakitale, ndipo umagwira ntchito yayikulu m'magawo ambiri. M'mbuyomu, nthawi zambiri ankanena kuti ufa wa graphite ndi njira yabwino yothetsera zida zowonongeka, ndipo makasitomala ambiri sakudziwa chifukwa chake. Lero, mkonzi wa Furuite Graphite afotokoza mwatsatanetsatane chifukwa chake mukunena izi:
Kuchita bwino kwambiri kwa ufa wa graphite kumapangitsa kuti ikhale yankho labwino kwambiri popewa kuwonongeka kwa zida.
1. Kusamva kutentha kwina. Kutentha kwa ntchito ya ufa wa graphite kumadalira mtundu wa zinthu zomwe zimapangidwira, monga phenolic resin impregnated graphite imatha kupirira 170-200 ℃, ndipo ngati kuchuluka kwa silicone resin impregnated graphite kuwonjezeredwa, kumatha kupirira 350 ℃. Pamene asidi phosphoric waikidwa pa carbon ndi graphite, ndi makutidwe ndi okosijeni kukana carbon ndi graphite akhoza bwino, ndipo kwenikweni ntchito kutentha akhoza zina kuwonjezeka.
2. Wabwino matenthedwe madutsidwe. Graphite ufa ulinso ndi matenthedwe abwino a matenthedwe, omwe ndi apamwamba kuposa achitsulo pakati pa zinthu zopanda zitsulo, zomwe zimayambira pakati pa zinthu zopanda zitsulo. Thermal conductivity ndi kawiri kuposa carbon steel ndi kasanu ndi kawiri kuposa zitsulo zosapanga dzimbiri. Choncho, ndizoyenera zipangizo zotumizira kutentha.
3. Zabwino kwambiri kukana dzimbiri. Mitundu yonse ya carbon ndi graphite imakhala ndi kukana kwa dzimbiri kwa hydrochloric acid, phosphoric acid ndi hydrofluoric acid, kuphatikiza media yomwe ili ndi fluorine. Kutentha kwa ntchito ndi 350 ℃-400 ℃, ndiko kuti, kutentha komwe mpweya ndi graphite zimayamba kukhala oxidize.
4. Pamwamba sikophweka kupanga. "Kugwirizana" pakati pa ufa wa graphite ndi zofalitsa zambiri ndizochepa kwambiri, choncho dothi silophweka kumamatira pamwamba. Makamaka zida condensation ndi crystallization zida.
Kufotokozera pamwambapa kungakupatseni kumvetsetsa mozama za ufa wa graphite. Qingdao Furuite Graphite imakhazikika pakukonza ndi kupanga graphite ufa, flake graphite ndi zinthu zina. Mwalandiridwa kuti mudzacheze ndikuwongolera fakitale yathu.
