Zozungulira zozungulira nthawi zambiri zimakhala zolimba komanso zimakhala ndi ntchito yabwino yodula, koma padzakhala palimodzi pakatha nthawi yayitali yogwiritsira ntchito, ndipo kuvala kumeneku kumagwirizana ndi zinthu zotsatirazi.
1.Materials
Kukaniza kolimba kwa zinthu zomwe zimagwiritsidwa ntchito popanga tsamba lozungulira ndi bwino, koma panthawi imodzimodziyo kulimba kumakhala kochepa. Kuuma ndi kulimba ndizosiyana, zomwenso ndi gawo lomwe liyenera kuwongoleredwa. Ngati ndi tsamba lozungulira la graphite, zinthuzo zitha kusankhidwa molimba mtima.
2. zokutira pamwamba
Masamba ozungulira okutidwa ndi diamondi ali ndi maubwino olimba kwambiri, kukana kwabwino kovala, komanso kugundana kocheperako, ndipo pakadali pano ndi njira yabwino yopangira. Komabe, mtengo wopanga ndi wokwera kwambiri, ndipo ukadaulo wapakhomo wapano mdera lino sunakhwime mokwanira. Masamba ozungulira okhala ndi graphite amagwiritsidwa ntchito kwambiri komanso othandiza.
Choncho, ngati mukufuna kuchepetsa kuvala kwa tsamba lozungulira, mukhoza kuika patsogolo zinthuzo ndi zokutira.
