Kodi kuyeretsa nkhungu graphite?

Nthawi zambiri, akamaumba akamaliza, dothi kapena zotsalira (zokhala ndi mankhwala enaake ndi zinthu zakuthupi) nthawi zambiri zimasiyidwagraphite nkhungu. Kwa mitundu yosiyanasiyana ya zotsalira, zofunikira zoyeretsera ndizosiyana. Utoto monga polyvinyl chloride umatulutsa mpweya wa hydrogen chloride, womwe umawononga mitundu yambiri ya chitsulo cha graphite die. Zotsalira zina zimasiyanitsidwa ndi zoletsa moto ndi ma antioxidants ndipo zimatha kuyambitsa dzimbiri kukhala chitsulo. Mitundu ina ya pigment ichita dzimbiri chitsulocho, ndipo dzimbirilo kumakhala kovuta kuchotsa. Ngakhale madzi ambiri osindikizidwa, ngati atayikidwa pamwamba pa nkhungu ya graphite yosasamalidwa kwa nthawi yaitali, idzawonongansographite nkhungu.
Chifukwa chake, nkhungu ya graphite iyenera kutsukidwa molingana ndi njira yomwe idakhazikitsidwa. Pambuyo graphite nkhungu kuchotsedwa atolankhani nthawi zonse, choyamba tsegulani graphite nkhungu mpweya dzenje kuchotsa makutidwe ndi okosijeni dothi ndi dzimbiri mu madera sanali ovuta a nkhungu graphite ndi Chinsinsi, kuti kupewa pang'onopang'ono dzimbiri pamwamba zitsulo ndi m'mphepete. Nthaŵi zambiri, ngakhale pambuyo poyeretsa, nkhungu zina za graphite zosakutidwa kapena za dzimbiri posachedwapa zidzasonyeza dzimbirinso. Choncho, ngakhale zimatenga nthawi yaitali kutsuka nkhungu yosatetezedwa ya graphite, maonekedwe a dzimbiri sangathe kupewedwa.
Nthawi zambiri, mapulasitiki olimba, mikanda yagalasi, zipolopolo za mtedza ndi tinthu tating'onoting'ono ta aluminiyamu amagwiritsidwa ntchito ngati abrasives.kuthamanga kwambirikuphwanya ndi kuyeretsa pamwamba pa nkhungu graphite, ngati abrasives izi ntchito kawirikawiri kapena mosayenera, njira akupera imeneyi adzapanganso pores padziko nkhungu graphite ndi zosavuta zotsalira kutsatira izo, chifukwa mu zotsalira zambiri ndi kuvala, Zingachititse kuti msanga akulimbana kapena burr wa nkhungu graphite, amene ndi kuyeretsa kwambiri graphite nkhungu unfavorable.
Tsopano, nkhungu zambiri za graphite zili ndi mizera “yodziyeretsa yokha,” yomwe imakhala yowala kwambiri. Pambuyo poyeretsa ndi kupukuta dzenje lotulukira mpweya kuti lifike pamlingo wopukutira wa spi#a3, kapena mphero kapena kugaya, tsitsani zotsalira kumalo a zinyalala za chitoliro chotulutsa mpweya kuti chotsaliracho chisatsatike pamwamba pa mphero. Komabe, ngati wogwiritsa ntchitoyo asankha coarse-grained flushing gasket, nsalu ya emery, sandpaper, grindstone kapena burashi yokhala ndi nayiloni bristle, mkuwa kapena chitsulo kuti akupera nkhungu ya graphite pamanja, zingayambitse "kuyeretsa" kwambiri kwa nkhungu ya graphite.
Choncho, pofufuza zipangizo zoyeretsera zoyenera nkhungu ya graphite ndi teknoloji yopangira makina komanso kutchula njira zoyeretsera ndi kuyeretsa zolembedwa m'mabuku osungidwa, nthawi yoposa 50% ya nthawi yokonza ikhoza kupulumutsidwa ndipo kuvala kwa nkhungu ya graphite kungachepetsedwe bwino.
