Njira yopanga mipukutu yayikulu yawaya wamalatandi mlingo wojambula, kupyolera mu nkhungu kukhala m'mimba mwake yaying'ono kuposa yoyamba.Ndi zina zotero mpaka kutalika komwe mukufuna.Mmodzi kukoka si zofunika, ayenera kuwerengedwa, kuchokera coarse kuti chabwino amadalira zitsulo ductility.Zikasintha kwambiri zimangosweka.Pambuyo kujambula kwa m'mimba mwake, kanasonkhezereka, kuti yomalizidwa mankhwala.
Panthawi imeneyi, waya akakokedwa, pamwamba pake amauma chifukwa cha kutentha kwambiri.Chifukwa chake nthawi zonse mukachikoka muyenera kuchikoka m'ng'anjo.Kumbali imodzi, ndiko kuchepetsa kuuma kwa pamwamba.Kumbali inayi, panthawi yomwe amakoka mawaya, pamwamba pawokha ndi opunduka, ndipo pakati sichisintha.Ndiye pali nkhawa zambiri mkati.Choncho, m'pofunika kudalira annealing kuti athetse vuto la mkati, kotero kuti waya ukhale wofewa kachiwiri kuti athetse kupsinjika maganizo asanakokedwe kachiwiri.
Koma pali zinthu zina zofunika kusamala popangawaya wamalata.Chotsani zida zonse ndi milu yomwe ili pamalo ogwirira ntchito ndi zida zomwe zimalepheretsa ntchito, ndipo pang'onopang'ono ikani waya mu silinda mukama pickling kuti asidi asatayike pathupi.Powonjezera asidi, asidi ayenera kuthiridwa pang'onopang'ono m'madzi.Musathire madzi mu asidi kuti asidi asatayike ndi kuvulaza.Ogwira ntchito ayenera kuvala magalasi odzitetezera akamagwira ntchito.Kenako pakugwira waya ndi zinthu zina, ndikoletsedwa kotheratu kukankha mwamphamvu.
Samalani chitetezo mu mzere kusonkhanitsa ndi ntchito, ena popanda chilolezo cha polojekiti, Ben ayenera kukwera basi ntchito.Ma reel amayenera kuyikidwa mopepuka, owunjikidwa mwamphamvu komanso mwaukhondo, osapitilira 5 reel.Kulumikizana mwachindunji ndi asidi ndi alkali kuyenera kuletsedwa.Pamene chifunga cha asidi chikuposa chandamale cha boma, ziyenera kuchitidwa kuti zithetse nthawi yake, apo ayi kupanga sikuloledwa.
Zinc yoyera imakhala yokhazikika mumpweya wowuma.Mu mpweya wonyowa kapena madzi okhala ndi mpweya woipa ndi okosijeni, pamwamba pake pamapanga zosanjikiza za zinki carbonate zochokera ku filimu yopyapyala, zomwe zingachedwetse kuwononga kwa nthaka wosanjikiza.Kuyerekeza kukana dzimbiri kwa nthaka ❖ kuyanika mu amadzimadzi njira ya asidi, alkali ndi sodium kolorayidi;Imalimbananso ndi dzimbiri mumlengalenga wokhala ndi mpweya woipa ndi hydrogen sulfide komanso mumlengalenga wanyanja;Mu kutentha ndi mkulu chinyezi mpweya ndi organic asidi m'mlengalenga ndi yaing'ono, kanasonkhezereka wosanjikiza ndi zosavuta dzimbiri.
