Zomwe zimafunikira pakukonza mapepala a graphite

Pepala la graphite ndi pepala lapadera lopangidwa kuchokera ku graphite ngati zopangira. Pamene graphite inkangofukulidwa pansi, inkangokhala ngati mamba, ndipo inali yofewa ndipo inkatchedwa graphite yachilengedwe. graphite iyi iyenera kukonzedwa ndikuyengedwa kuti ikhale yothandiza. Choyamba, zilowerereni masoka a graphite mu osakaniza a sulfuric acid wokhazikika ndi asidi wa nitric kwa nthawi ndithu, kenaka mutulutseni, muzimutsuka ndi madzi, muumitse, ndiyeno muyike mu ng'anjo yotentha kwambiri kuti muyaka. Mkonzi wotsatira wa Furuite graphite akuyambitsa zofunikira kuti apange pepala la graphite:

Chifukwa zolowetsa pakati pa ma graphite zimasanduka nthunzi mofulumira pambuyo potenthedwa, ndipo nthawi yomweyo, voliyumu ya graphite imakula mofulumira ndi maulendo angapo kapena mazana, kotero kuti graphite yotakata imapezeka, yomwe imatchedwa "graphite yowonjezera". Pali ziboda zambiri (zotsalira pambuyo pa kuchotsedwa kwa inlays) mu graphite yowonjezera, yomwe imachepetsa kwambiri kachulukidwe ka graphite, yomwe ndi 0.01-0.059 / cm3, yopepuka kulemera komanso yabwino kwambiri pakutentha kwa kutentha. Chifukwa pali mabowo ambiri, makulidwe osiyanasiyana, ndi kusagwirizana, amatha kuwoloka wina ndi mzake pamene mphamvu yakunja ikugwiritsidwa ntchito. Uku ndiko kudziphatika kwa graphite yowonjezera. Malinga ndi kudziphatika kwa graphite yowonjezera, imatha kusinthidwa kukhala pepala la graphite.

Choncho, chofunika kwambiri pakupanga mapepala a graphite ndi kukhala ndi zida zonse, ndiko kuti, chipangizo chokonzekera graphite yowonjezera kuchokera kumizidwa, kuyeretsa, kuyaka, ndi zina zotero, momwe muli madzi ndi moto. Ndikofunikira makamaka; yachiwiri ndi kupanga mapepala ndi kukanikiza makina odzigudubuza. Kuthamanga kwa mzere wa wodzigudubuza sikuyenera kukhala kwakukulu, mwinamwake kungakhudze kufanana ndi mphamvu ya pepala la graphite, ndipo ngati kuthamanga kwa mzere kuli kochepa kwambiri, kumakhala kosavomerezeka. Choncho, ndondomeko yopangidwira iyenera kukhala yolondola, ndipo pepala la graphite likuwopa chinyezi, ndipo pepala lomalizidwa liyenera kuikidwa muzosunga zosungira chinyezi ndikusungidwa bwino.
