Dzimbiri loyera ndi post-galvanizing phenomenon. Udindo wa kupewa kwake uli m'njira yopakidwa, kusamaliridwa ndi kusungidwa ndi malata asanakhazikitsidwe ndikugwiritsa ntchito. Kukhalapo kwa dzimbiri loyera sikuwonetsetsa ntchito ya ❖ kuyanika kwa malata, koma udindo wa onse omwe akugwira nawo ntchitoyi kuti awonetsetse kuti zomwe zimayambitsa dzimbiri zoyera zimadziwika ndipo kuopsa kwake kumachepetsedwa pazitsulo zatsopano zamalata. Zikafika ku China chitoliro choviikidwa chamalata, komwe zitsulo zatsopano zimayikidwa m'madzi oyera (mvula, mame kapena condensation), m'malo opanda mpweya, madzi apitiliza kuchitapo kanthu ndi zinki ndikuwononga ❖ kuyanika. Chikhalidwe chofala kwambiri chomwe dzimbiri loyera limachitika ndi zinthu zokhala ndi malata zomwe zimamangidwa pamodzi, zopakidwa mwamphamvu, kapena pamene madzi amatha kulowa pakati pa zinthuzo ndikukhalabe kwa nthawi yayitali.
Nthawi zambiri, madzi oyera (H2O) alibe mchere wosungunuka kapena mchere ndipo zinki amatha kuchitapo kanthu mwachangu ndi madzi oyera kuti apange zinc hydroxide, yoyera yoyera komanso yosakhazikika ya oxide ya zinc. Ngalande yachitsulo imakhala ndi zokutira zopyapyala za zinki zomwe zimaphatikizidwa kugawo lachitsulo. Kuphatikiza kumeneku kumapereka zinthu zomwe zimakhala ndi zida zamakina zachitsulo zomwe zimalimbikitsidwa ndi kukana kwa dzimbiri kwa nthaka. Komabe, pamene malo opangidwa ndi galvanized akuwukiridwa ndipo zinc hydroxide pawiri apanga, ndi zofunika kuchotsa okusayidi mankhwala kuchokera pamwamba chifukwa: 1) kukhalapo kwawo linalake ndipo tikulephera mapangidwe khola carbonate zochokera oxides; 2) ndi zosawoneka.
Pankhani ozizira adagulung'undisa zitsulo chitoliro, kachiwiri passivating kanasonkhezereka padziko ndi chinthu china chofunika kwambiri mankhwala chitoliro zitsulo mu utumiki. Makamaka, pamene dzimbiri zoyera zachitika ndipo chinthucho chikhoza kupitiriza kuwonetseredwa zomwe zingathe kufalitsa dzimbiri zofanana, kubwezeretsanso pamwamba kungathe kuchitidwa pochiza pamwamba ndi yankho la 5% sodium dichromate 0.1% sulfuric acid, kupaka ndi burashi yolimba yawaya kwa masekondi 30 musanayambe kutsuka pamwamba. Monga katswiri wopanga machubu aku China ku China, tikufuna kukupatsani njira zingapo zosavuta zomwe zingachepetse kapena kuthetsa kupangika kwa dzimbiri loyera motere:
• Ntchito yopakidwa ikhale yowuma
• Longetsani zinthuzo kuti mpweya uziyenda pakati pa malo
• Sunjikirani zinthuzo kuti madzi atuluke
• Thirani pamwamba ndi zotchingira madzi kapena zotchingira zotchingira kuti musakhumane ndi chinyezi ndi malata.
