Pamene fakitale yamagetsi ya nyukiliya yatsekedwa kuti iwonjezere mafuta -- njira yomwe ingatenge chaka chonse kuti mpweya usakhale ndi chinyezi imatha kusunga zinthu zina zosakhala za nyukiliya monga ma boiler, ma condenser, ndi ma turbine kuti zisakhale ndi dzimbiri.

Vuto la chinyezi m'makampani opanga pulasitiki limayambitsidwa makamaka ndi kuuma kwa nkhungu pamwamba pa nkhungu komanso kusokonezeka komwe kumachitika chifukwa cha chinyezi chomwe chimayamwa ndi pulasitiki. Kuchepetsa chinyezi sikuti kumangowonjezera ubwino wa chinthucho, komanso kumawonjezera kupanga.
Mphamvu ya chinyezi pa ubwino wa zinthu za pulasitiki: panthawi yopangira zinthu za pulasitiki pogwiritsa ntchito jakisoni, thermoplastic imatenthedwa kaye, kenako nkhungu imagwiritsidwa ntchito kupanga mawonekedwe enaake. Chifukwa cha utomoni wambiri wa pulasitiki womwe uli ndi hygroscopicity, mu njira yopangira jakisoni, ngati zinthu zopangira ndi chinyezi, zimatulutsa zinthu zopangira pambuyo pa nthunzi yamadzi otentha zimatha kubweretsa zolakwika pa kapangidwe ndi mawonekedwe omaliza. Pofuna kukonza bwino mtundu wa chinthucho, kuchotsa chinyezi kumafunika musanagwiritse ntchito zinthu za pulasitiki. Mphamvu ya chinyezi pa zokolola za zinthu za pulasitiki: nthawi zambiri, kutentha kwambiri kumawonjezera nthawi yopangira ndikuchepetsa kutulutsa. Kutentha kwa nkhungu kukakhala kotsika, kumapangidwa mwachangu. Mu njira yopangira jakisoni wa pulasitiki, machitidwe ambiri amagwiritsa ntchito madzi ozizira kuti achepetse kutentha kwa nkhungu kuti asunge nthawi yopangira ndikuwonjezera kupanga. Komabe, kutentha kwa nkhungu kotsika kwambiri kumabweretsa kuzizira, makamaka nthawi yachilimwe komwe kumakhala kofala kwambiri. Izi zimapangitsa kuti madzi azithira pa zinthu zomalizidwa, dzimbiri la nkhungu zokwera mtengo, komanso ndalama zambiri zosamalira ndi kusintha. Pogwiritsa ntchito chochotsera chinyezi cha gudumu, mpweya wochotsa chinyezi ukhoza kulamulidwa kuti upewe kuzizira panthawi yozizira.
