Tanthauzo la Zamalonda
Chophimba chachitsulo chopakidwa kale ndi chinthu chopangidwa ndi chitsulo chotentha choviikidwa m'madzi, chitsulo chotentha choviikidwa m'madzi, chitsulo chopangidwa ndi magetsi, ndi zina zotero, chomwe chimakutidwa ndi chimodzi kapena zingapo za utoto wachilengedwe pamwamba pake pambuyo pokonza pamwamba (kuchotsa mafuta ndi kusintha kwa mankhwala), kenako nkuchiritsidwa pogwiritsa ntchito kuphika. Dzina lake limatchedwa dzina lakoyilo yachitsulo yokutidwa ndi utotoyokhala ndi mitundu yosiyanasiyana ya zokutira zachilengedwe, ndipo imatchedwa coil yachitsulo yopakidwa kale.

Njira Yopangira Chitsulo Chopakidwa Painting
Pali njira zambiri zopangira zinthu zopakidwa kalezitsulo zophimbidwa ndi utotoNjira yomwe imagwiritsidwa ntchito kwambiri ndi njira yachikhalidwe yophikira ndi kuphika. Popeza zokutira zambiri zomangira zimakhala ndi zokutira kawiri, njira yachikhalidwe yophikira kawiri ndi kuphika kawiri ndiyo njira yodziwika bwino yopangira zokutira mitundu. Njira zazikulu zophikira mitundu zimaphatikizapo kukonzekera, kuphimba, ndi kuphika.
Kapangidwe ka Chitsulo Chopakidwa Kale
1) Chophimba chapamwamba: imateteza kuwala kwa dzuwa ndipo imaletsa kuwala kwa ultraviolet kuwononga chophimbacho; chophimba chapamwamba chikafika pa makulidwe ofunikira, chimatha kupanga filimu yolimba yotetezera chophimbacho, kuchepetsa kulowa kwa madzi ndi kulowa kwa mpweya.
Chophimba cha primer: chimathandiza kulimbitsa kumamatira ku substrate, zomwe zimapangitsa kuti utoto usasunthe utoto pambuyo poti utoto walowetsedwa ndi madzi, komanso chimathandizira kukana dzimbiri, chifukwa primer ili ndi utoto woletsa dzimbiri, monga utoto wa chromate, womwe umalepheretsa anode ndikuwonjezera kukana dzimbiri.
2) Kutembenuka kwa mankhwala: kumathandizira kuti mbale (yokhala ndi galvanized, galvalume, zn-al-mg, ndi zina zotero) ikhale yolumikizana bwino ndi utoto (utoto).
3) Chitsulo chophikira: nthawi zambiri utoto wa zinc, utoto wa aluzinc ndi utoto wa zinc aluminium magnesium, zomwe zimakhudza kwambiri moyo wa ntchito ya chinthucho. Mtundu wachitsulo ukakhala wokhuthala, umakhala wolimba kwambiri chifukwa cha dzimbiri.
4) Chitsulo choyambira: mbale yozungulira yozizira imagwiritsidwa ntchito, ndipo makhalidwe osiyanasiyana amatsimikizira momwe mbale yamitundu imagwirira ntchito, monga mphamvu
5) Chophimba pansi: imaletsa mbale yachitsulo kuti isawonongeke kuchokera mkati, nthawi zambiri imakhala ndi zigawo ziwiri (2/1M kapena 2/2 primer coating + pansi coating), ngati igwiritsidwa ntchito ngati mbale yophatikizana, ndi bwino kugwiritsa ntchito kapangidwe ka gawo limodzi (2/1)
