Chitsulo cha mowa ndi chakumwa ndi mtundu wa kulongedza chakudya, ndipo sayenera kuwonjezera monyanyira ku mtengo wa zomwe zilimo. Opanga zitini nthawi zonse amafunafuna njira zopangira paketi kukhala yotchipa. Kamodzi chitini chinapangidwa mu zidutswa zitatu: thupi (kuchokera pepala lathyathyathya) ndi malekezero awiri. Tsopano zitini zambiri zamowa ndi zakumwa zimakhala zitini ziwiri. Thupi limapangidwa kuchokera kuchitsulo chimodzi ndi njira yotchedwa kujambula ndi kusita khoma.

Njira yomangirayi imalola kuti chitsulo chochepa kwambiri chigwiritsidwe ntchito ndipo chitinicho chimakhala ndi mphamvu zambiri pokhapokha atadzazidwa ndi chakumwa cha carbonated ndikusindikizidwa. Spin-necking imapulumutsa chitsulo pochepetsa kukula kwa khosi. Pakati pa 1970 ndi 1990, zotengera mowa ndi zakumwa zidakhala zopepuka ndi 25%. Ku USA, komwe aluminium ndi yotsika mtengo, zitini zambiri za mowa ndi zakumwa zimapangidwa kuchokera kuchitsulo chimenecho. Ku Ulaya, tinplate nthawi zambiri imakhala yotsika mtengo, ndipo zitini zambiri zimapangidwa ndi izi. Mowa wamakono ndi chakumwa cha tinplate chili ndi malata otsika pamwamba, ntchito zazikulu za malata zimakhala zodzikongoletsera komanso zopaka mafuta (pojambula). Chifukwa chake lacquer yokhala ndi chitetezo chabwino kwambiri imafunikira, kuti igwiritsidwe ntchito polemera malaya ochepa (6-12 µm, kutengera mtundu wachitsulo).

Kupanga zitini kumakhala kopanda ndalama pokhapokha ngati zitini zitha kupangidwa mwachangu kwambiri. Zitini 800-1000 pa mphindi imodzi zidzapangidwa kuchokera ku mzere umodzi wokutira, ndi matupi ndi malekezero okutidwa padera. Matupi amowa ndi zitini za zakumwa amapangidwa ndi lacquered atapangidwa ndi kuchotsedwa. Kugwiritsa ntchito mwachangu kumatheka ndi kuphulika kwakanthawi kopanda mpweya kopanda mpweya kuchokera pamkondo womwe uli moyang'anizana ndi pakati pa kumapeto kwa chitini chopingasa. Mkondowo ukhoza kukhala wosasunthika kapena ukhoza kulowetsedwa mu chitini kenako nkuchotsedwa. Chitsulocho chimasungidwa mu chuck ndikuzunguliridwa mwachangu popopera mbewu mankhwalawa kuti apeze zokutira zofananira kwambiri. Kupaka viscosity kuyenera kukhala kochepa kwambiri, ndi zolimba za 25-30%. Maonekedwe ake ndi osavuta, koma zamkati zimachiritsidwa ndi mpweya wotentha wotentha, mumadongosolo ozungulira 3 min pa 200 ° C.

Zakumwa zoziziritsa kukhosi zimakhala ndi acidic. Kukana dzimbiri ndi zinthu zoterezi kumaperekedwa ndi zokutira monga epoxy-amino resin kapena epoxy-phenolic resin systems. Mowa ndiwosautsa kwambiri pachitini, koma kukoma kwake kumatha kuwonongeka mosavuta ndi kutola chitsulo kuchokera pachitini kapena ndi zinthu zomwe zimachotsedwa mu lacquer, zomwe zimafunikiranso ma lacquers apamwamba kwambiri amkati.

Zambiri mwa zokutira izi zasinthidwa bwino kukhala machitidwe opangidwa ndi madzi opangidwa ndi colloidally omwazika kapena emulsion polima, makamaka pa gawo lapansi losavuta kuteteza, aluminiyamu. Zovala zokhala ndi madzi zachepetsa ndalama zonse ndikutsitsa zosungunulira zomwe ziyenera kutayidwa ndi zowotcha pambuyo pake kuti zipewe kuipitsidwa. Machitidwe opambana kwambiri amachokera ku epoxy-acrylic copolymers ndi amino kapena phenolic crosslinkers.

Pakupitirizabe kukhala ndi chidwi chamalonda mu electrodeposition ya lacquers madzi opangidwa ndi mowa ndi zakumwa zitini. Njira yotereyi imapewa kufunikira koyika mu malaya awiri, ndipo imatha kupereka zokutira zopanda chilema zosagwirizana ndi zomwe zili mubokosi pazithunzi zotsika zowuma. Mu zokutira zopopera madzi, zosungunulira zochepera 10-15% zimafunidwa.
