M'zaka zaposachedwa, nkhungu ya graphite mumakampani amakono ogwiritsira ntchito mafakitale akupitilizabe kukulitsa malo ake, nthawi ino ndi yosiyana ndi yakale, nkhungu yamakono ya graphite ili kale m'tsogolomu.
Choyamba, kuvala kukana
Chifukwa chomwe nkhungu za graphite nthawi zambiri zimalephera chifukwa chakuvala ndikuti billet ikapangidwa ndi pulasitiki mu nkhungu, imayenda ndikutsetsereka pamwamba pa mtsempha, zomwe zimapangitsa kuti pakhale kukangana kwakukulu pakati pa nsonga ndi billet.
1, kukana kuvala kumakhudzana ndi kuchuluka, kukula, mawonekedwe, mtundu ndi kugawa kwa ma carbides pazinthuzo
2, imodzi mwazinthu zofunika kwambiri za nkhungu ya graphite ndi kukana kwa zinthu;
3, chinthu chachikulu chomwe chimakhudza kukana kuvala ndi kuuma. Kuchuluka kwa kuuma kwa ziwalo za graphite, kucheperachepera kwa mavalidwe, kumapangitsanso kukana kuvala;
Chachiwiri, mphamvu ndi kulimba
Nthambi za graphite nthawi zambiri zimagwiritsidwa ntchito m'malo ovuta, ndipo zina zimafunikira kupirira kuchuluka kwamphamvu, zomwe zimapangitsa kuti zisawonongeke. Ndizinthu zamtengo wapatali za graphite zolimba kwambiri komanso zolimba, zomwe zimathandiza kupewa kuwonongeka kwadzidzidzi kwa nkhungu panthawi ya ntchito. Kulimba kumalumikizidwa makamaka ndi microstructure, kukula kwambewu ndi kaboni wazinthuzo.
