Makhalidwe a nkhungu ya graphite ndi zida zogwirira ntchito

M'zaka zaposachedwapa, nkhungu ya graphite m'makampani amakono ogwiritsira ntchito mafakitale ikupitiliza kukulitsa malo ake, nthawi ino ndi yosiyana ndi yakale, nkhungu ya graphite yomwe ilipo tsopano ndi chizolowezi mtsogolo.

Choyamba, kukana kuvala

Chifukwa chomwe mapangidwe a graphite nthawi zambiri amalephera chifukwa cha kuwonongeka ndichakuti pamene billet yawonongeka ndi pulasitiki m'bowo la nkhungu, imathamanga ndikutsetsereka pamwamba pa bowo, zomwe zimapangitsa kuti pakhale kukangana kwakukulu pakati pa pamwamba pa bowo ndi billet.

1, kukana kuvala kumakhudzana ndi kuchuluka, kukula, mawonekedwe, mtundu ndi kufalikira kwa ma carbide muzinthuzo

2, chimodzi mwazinthu zofunika kwambiri za nkhungu ya graphite ndi kukana kwa zinthuzo;

3, chinthu chachikulu chomwe chimakhudza kukana kuvala ndi kuuma. Kuuma kwa zigawo za graphite kukakhala kwakukulu, kuchepa kwa kuvala kumakhala kochepa, kukana kuvala kumakhala bwino;

Chachiwiri, mphamvu ndi kulimba

Zinyalala za graphite nthawi zambiri zimagwiritsidwa ntchito pamalo ovuta, ndipo zina zimafunika kupirira kugwedezeka kwakukulu, zomwe zimapangitsa kuti zisweke mosavuta. Ndi zinthu za graphite zoyera kwambiri zomwe zimakhala zolimba komanso zolimba, zomwe zimathandiza kupewa kusweka mwadzidzidzi kwa ziwalo za nkhungu panthawi yogwira ntchito. Kulimba kwake kumakhudzana kwambiri ndi kapangidwe kake kakang'ono, kukula kwa tirigu ndi kuchuluka kwa kaboni m'zinthuzo.
