Kodi mungatsuke bwanji nkhungu ya graphite?

Kawirikawiri, ntchito youmba ikatha, dothi kapena zotsalira (zokhala ndi mankhwala enaake ndi zinthu zina zakuthupi) nthawi zambiri zimasiyidwa pagraphite nkhungu. Pa mitundu yosiyanasiyana ya zotsalira, zofunikira pakuyeretsa nazonso zimasiyana. Ma resin monga polyvinyl chloride amapanga mpweya wa hydrogen chloride, womwe umawononga mitundu yambiri ya chitsulo cha graphite. Zotsalira zina zimalekanitsidwa ndi zoletsa moto ndi ma antioxidants ndipo zimatha kuyambitsa dzimbiri ku chitsulo. Mitundu ina ya utoto imapanga dzimbiri ku chitsulocho, ndipo dzimbirilo ndi lovuta kuchotsa. Ngakhale madzi otsekedwa, ngati atayikidwa pamwamba pa nkhungu ya graphite yosakonzedwa kwa nthawi yayitali, ingayambitsenso kuwonongeka kwagraphite nkhungu.
Chifukwa chake, nkhungu ya graphite iyenera kutsukidwa malinga ndi nthawi yopangira yomwe yakhazikitsidwa. Nkhungu ya graphite ikachotsedwa mu makina nthawi iliyonse, choyamba tsegulani dzenje la mpweya wa graphite kuti muchotse dothi lonse la okosijeni ndi dzimbiri m'malo osafunikira a nkhungu ya graphite ndi template, kuti isawononge pang'onopang'ono pamwamba pa chitsulo ndi m'mphepete. Nthawi zambiri, ngakhale mutatsuka, nkhungu zina za graphite zosaphimbidwa kapena zozizira zidzawonetsanso dzimbiri posachedwa. Chifukwa chake, ngakhale zitatenga nthawi yayitali kutsuka nkhungu ya graphite yosatetezedwa, dzimbiri looneka silingapewedwe kotheratu.
Kawirikawiri, mapulasitiki olimba, mikanda yagalasi, zipolopolo za mtedza ndi tinthu ta aluminiyamu zimagwiritsidwa ntchito ngati zokometserakuthamanga kwambiriKuphwanya ndi kuyeretsa pamwamba pa nkhungu ya graphite, ngati zopopera izi zikugwiritsidwa ntchito mobwerezabwereza kapena molakwika, njira yopukutira iyi ipangitsanso kuti ma pores pamwamba pa nkhungu ya graphite akhale osavuta kumamatira, zomwe zimapangitsa kuti zotsalira zambiri ziwonongeke. Zingayambitse kusweka msanga kapena kuphulika kwa nkhungu ya graphite, zomwe sizikugwirizana ndi kuyeretsa nkhungu ya graphite.
Tsopano, nkhungu zambiri za graphite zili ndi mipata yotulukira mpweya "yodziyeretsa yokha", yomwe imakhala yonyezimira kwambiri. Mukatsuka ndikupukuta dzenje la mpweya kuti mufike pamlingo wopukuta wa spi#a3, kapena kugaya kapena kupukuta, tulutsani zotsalirazo kumalo otayira zinyalala a chitoliro chotulukira mpweya kuti mupewe zotsalira kuti zisamamatire pamwamba pa maziko a mphero yozungulira. Komabe, ngati wogwiritsa ntchito asankha gasket yothira madzi, nsalu ya emery, sandpaper, grindstone kapena burashi yokhala ndi bristle ya nayiloni, mkuwa kapena chitsulo kuti mupukute nkhungu ya graphite pamanja, izi zipangitsa kuti nkhungu ya graphite "itsukidwe" kwambiri.
Chifukwa chake, pofufuza zida zoyeretsera zoyenera kugwiritsa ntchito ukadaulo wa graphite ndi kukonza zinthu komanso kugwiritsa ntchito njira zoyeretsera ndi njira zoyeretsera zomwe zalembedwa m'makalata osungidwa, nthawi yoposa 50% yokonza zinthu ikhoza kupulumutsidwa ndipo kuwonongeka kwa graphite kungachepe bwino.
