Mawonekedwe a flake graphite omwe amagwiritsidwa ntchito mu nkhungu

M'zaka zaposachedwa, mafakitale a nkhungu a graphite apangidwa ndi kudumpha ndi malire, ndipo zojambula zomwe zakonzedwa ndizosavuta kupanga, zapamwamba kwambiri, ndipo palibe zotsalira pakuponyedwa komweko. Pofuna kukwaniritsa makhalidwe pamwamba, nkhungu ndi sikelo graphite ayenera kusankha ufulu pokonza, lero Furuite graphite xiaobian angakuuzeni za makhalidwe nkhungu ndi sikelo graphite:

Makhalidwe a flake graphite pa nkhungu (FIG. 1)

Choyamba, kutentha kokwanira kwa nkhungu flake graphite ndipamwamba. Kuthamanga kozizira kumathamanga ndipo kuponyera kumatha kuchotsedwa mwachangu pogwiritsa ntchito nkhungu za graphite.

Awiri, ndi mphamvu zina zamakina. Kutentha kwa kuponyera kukakwera, nkhungu iyenera kukhalabe ndi mawonekedwe ake, kuti kuponyerako kupangidwe bwino.

Chachitatu, choyezera chowonjezera chamafuta ndi chaching'ono, kukana kutentha kumakhudza magwiridwe antchito amphamvu. Maonekedwe a nkhungu ndi kusintha kwa kukula kwake kumakhala kochepa pamene akutenthedwa ndi kuzizira, kotero n'zosavuta kusunga kulondola kwa kuponyera.

Chachinayi, khalani ndi magwiridwe antchito abwino.

Zisanu, graphite okusayidi mwachindunji mpweya volatilization, workpiece sangasiye zotsalira.
