Chidziwitso Chachidziwitso cha Mapepala Azitsulo

Pepala lopangidwa ndi galvanized limatanthawuza pepala lachitsulo lokhala ndi malata pamwamba.Zinc wosanjikiza amatha kuteteza dzimbiri chifukwa cha zomwe zimachitika pakati pa pepala lachitsulo ndi mpweya kapena kusintha kwa mankhwala ndi zinthu zamakina zomwe zimayambitsidwa ndi kukhudzana ndi zinthu zina, ndipo zimatha kusintha kwambiri moyo wautumiki ndi kukhazikika kwachitsulo.

zitsulo mbale kanasonkhezereka amagawidwa mu mbale wamba electrolytic ndi zala kugonjetsedwa ndi electrolytic mbale.Mbale yosagwira zala ndi chithandizo chala chala chomwe chimawonjezeredwa ku mbale wamba ya electrolytic, yomwe imatha kukana thukuta.Amagwiritsidwa ntchito pazigawo zomwe sizimathandizidwa, ndipo mtunduwo ndi secc-n.Board wamba electrolytic akhoza kugawidwa mu phosphating board ndi passivation board.Phosphating imagwiritsidwa ntchito kwambiri.Mtunduwu ndi secc-p, womwe umadziwika kuti P.Passivation mbale akhoza kugawidwa mu oiled and non oiled.They makamaka ntchito yomanga, zipangizo kunyumba, magalimoto, muli, mayendedwe, makampani kunyumba ndi zina.Makamaka pakupanga zitsulo, kupanga magalimoto, kupanga zitsulo zosungiramo katundu ndi mafakitale ena.Makhalidwe awo akuluakulu ndi: kukana kwamphamvu kwa dzimbiri, khalidwe labwino la pamwamba, kupindula ndi kukonza kwambiri, zachuma ndi zothandiza.Chitsulo chamtundu uwu chimapangidwanso ndi njira yoviyitsa yotentha, koma ikatuluka mumphako, imatenthedwa nthawi yomweyo mpaka pafupifupi 500 ℃ kupanga zokutira za aloyi za zinki ndi chitsulo.Koyilo yamagetsi yamtunduwu imakhala ndi zomatira zabwino komanso zowotcherera.
