Zikafika popanga zisankho zolondola komanso zapamwamba, mtundu wachubu cha nkhungukugwiritsidwa ntchito kumakhala ndi gawo lalikulu pazotsatira zomaliza.Mtundu umodzi wa chubu wa nkhungu womwe watchuka kwambiri m'zaka zaposachedwa ndi chubu cha square mold, makamaka theCuAg nkhungu machubu.Machubuwa amapereka maubwino osiyanasiyana ndipo amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa chosinthasintha komanso kukhazikika.

Square nkhungu machubu, amadziwikanso kutimachubu a nkhungu, amapangidwa kuti apereke mawonekedwe okhazikika komanso ofanana ndi zojambulajambula zomwe amapanga.Izi ndizofunikira makamaka m'mafakitale monga kupanga zodzikongoletsera, komwe kulondola ndikofunikira.Maonekedwe apakati a machubuwa amalola kuti pakhale nkhungu yokhazikika, zomwe zimapangitsa kuti pakhale zinthu zomalizidwa bwino kwambiri.

Machubu a nkhungu a CuAg, opangidwa makamaka ndi ma aloyi amkuwa ndi siliva, amadziwika chifukwa cha kutentha kwawo komanso kukana dzimbiri.Izi zimawapangitsa kukhala abwino kuti azigwiritsidwa ntchito popanga nkhungu zovuta komanso zatsatanetsatane.Kuphatikizana kwa mkuwa ndi siliva kumaperekanso malo osalala, omwe ndi ofunikira kuti apange nkhungu zopanda cholakwika.

Ubwino umodzi wogwiritsa ntchito machubu akulu akulu, makamaka machubu a CuAg, ndikutha kupirira kutentha kwambiri.Izi ndizofunikira makamaka muzinthu monga kuponyera zitsulo, kumene machubu a nkhungu amakumana ndi kutentha kwakukulu.Kukhalitsa kwa machubuwa kumatsimikizira kuti amatha kusunga mawonekedwe awo ndi kukhulupirika ngakhale pansi pa kutentha kwakukulu, zomwe zimapangitsa kuti zikhale zokhazikika komanso zodalirika.

Kuphatikiza apo, kusinthasintha kwa machubu amtundu wa square mold kumafikira pakulumikizana kwawo ndi zida zosiyanasiyana zomangira.Kaya ndi sera, utomoni, kapena chitsulo, machubuwa amatha kukhala ndi zida zambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mosiyanasiyana.

Pomaliza, machubu a square mold, makamaka CuAg mold chubu, amapereka kuphatikiza kulondola, kulimba, komanso kusinthasintha komwe kumawapangitsa kukhala chida chofunikira popanga nkhungu.Kukhoza kwawo kupirira kutentha kwakukulu ndikukhala ndi zipangizo zosiyanasiyana zomangira zimawapangitsa kukhala ofunika kwambiri m'mafakitale omwe amafunikira nkhungu mosamala komanso zapamwamba.Pamene ukadaulo ukupitilirabe patsogolo, kufunikira kwa njira zatsopano zamachubu a nkhungu ngati machubu a CuAg akuyembekezeka kukula, kulimbitsa malo awo popanga ndi kupanga.
