M'zaka zaposachedwapa, ndi ntchito yaikulu ya nkhungu graphite, pachaka mowa mtengo wa zisamere pachakudya mu makampani makina ndi 5 nthawi okwana mtengo wa mitundu yonse ya zida makina, ndi kutaya kwakukulu kutentha ndi zosiyana kwambiri ndi mphamvu alipo. -kupulumutsa ndondomeko ku China.The lalikulu mowa zisamere pachakudya osati mwachindunji kumawonjezera mtengo wa mabizinezi, komanso kumabweretsa pafupipafupi kupanga mzere shutdowns chifukwa cha m'malo pafupipafupi zisamere pachakudya, potsiriza kuchititsa imfa yaikulu zachuma.
Malinga ndi kafukufuku, chifukwa nkhungu zopangira ndi mphamvu mitengo ananyamuka kwambiri ndi zifukwa zina, ndi nkhungu makampani mankhwala phindu linagwa chaka chatha; Kuti apulumuke ndi kukhala, mabizinesi ambiri kutengera
Kusintha kwa zinthu kumagwiritsidwa ntchito ngati njira yayikulu yosinthira ndi chitukuko. Zimamveka kuti makampani ambiri adayambitsa zida zotulutsa ma graphite spark, mukupanga nkhungu ikuchita gawo lofunikira kwambiri. Machining mwatsatanetsatane ndi zotsatira zabwino pamwamba, makamaka mu nkhungu patsekeke processing mwatsatanetsatane, zovuta, khoma woonda, mkulu zinthu zolimba ali advantage.Poyerekeza ndi mkuwa, graphite zakuthupi ali ndi ubwino monga kumwa mochepa, mofulumira kukhetsa liwiro, kulemera kuwala ndi zazing'ono. Kukula kokwanira kwamafuta, kotero kuti elekitirodi yamkuwa yakhala pang'onopang'ono kukhala gawo lalikulu lazinthu zopangira zotulutsa. Mosiyana ndi izi, zida za graphite elekitirodi zili ndi zabwino zisanu ndi chimodzi izi:
1. Kuthamanga kwachangu; Kutulutsa kwa graphite ndikothamanga kwambiri 2-3 kuposa mkuwa, ndipo zinthuzo sizosavuta kupunduka. Iwo ali ubwino zoonekeratu pokonza woonda analimbitsa elekitirodi. Kufewetsa kwa mkuwa kuli pafupifupi madigiri 1000, ndipo ndikosavuta kupunduka chifukwa cha kutentha.
2. Kulemera kopepuka;Kuchulukana kwa graphite ndi 1/5 yokha ya mkuwa. Pamene electrode yaikulu ikukonzedwa ndi kutulutsa, katundu wa chida cha makina (EDM) akhoza kuchepetsedwa bwino, omwe ali oyenera kugwiritsa ntchito nkhungu yaikulu.
3. Kuwonongeka kwakung'ono; Popeza kuti mafuta a spark amakhala ndi maatomu a C, kutentha kwakukulu kumapangitsa kuti maatomu a C mu mafuta a spark awonongeke panthawi yotulutsa utsi, ndipo filimu yoteteza imapangidwa pamwamba pa electrode ya graphite, yomwe imabwezera kutaya kwa electrode ya graphite.
4. Palibe ma burrs; Pambuyo pokonza electrode yamkuwa, ma burrs ayenera kuchotsedwa pamanja. Komabe, palibe ma burrs pambuyo pa kukonzedwa kwa graphite, zomwe sizimangopulumutsa ndalama zambiri ndi ogwira ntchito, komanso zimapangitsa kuti zikhale zosavuta kuzindikira kupanga zokha.
5. Kupukuta kosavuta; Chifukwa kukana kudula kwa graphite ndi 1/5 yokha ya mkuwa, ndikosavuta kugaya ndi kupukuta ndi dzanja.
Vi. Mtengo wotsika; Chifukwa cha kukwera mtengo kwa mkuwa m'zaka zaposachedwa, mtengo wa graphite m'mbali zonse ndi wotsika kuposa wamkuwa. Pansi pa voliyumu yomweyi ya chilengedwe cha Oriental carbon, mtengo wazinthu za graphite ndi 30% mpaka 60% kutsika kuposa. kuti yamkuwa, mtengo wake ndi wokhazikika, ndipo kusinthasintha kwanthawi kochepa kwamitengo kumakhala kochepa. Ndi kusungitsa mphamvu, kuteteza chilengedwe ndi kukonza bwino kukhala gawo lalikulu lamakampani opanga zinthu, zida za graphite elekitirodi pang'onopang'ono zidzalowa m'malo mwa elekitirodi yamkuwa ndikusewera yofunika kwambiri. udindo mu EDM. Mofananamo, mumpikisano wochuluka kwambiri mumsika wa nkhungu masiku ano, kugwiritsa ntchito zipangizo zamakono zopangira makina opanga nkhungu zapamwamba ndi njira yabwino kwambiri kuti mabizinesi apambane msika ndi makasitomala.
