Chitoliro chachitsulo chotentha choviikidwa ndi galvanized, yomwe imadziwikanso kutichitoliro chotentha choviikidwa ndi galvanized, ndi chitoliro chachitsulo chomwe chimapangidwa ndi galvanized kuti chigwiritsidwe ntchito bwino. Mfundo yake yogwiritsira ntchito ndi kupanga ndikupangitsa chitsulo chosungunuka kuti chigwirizane ndi chitoliro chachitsulo kuti chipange gawo la alloy, kuti chitoliro ndi zokutira zigwirizane. Kodi ndi motanimapaipi achitsulo opangidwa ndi galvanized otenthaKuyenda kwa chitoliro chachitsulo chotenthedwa ndi madzi otentha kumagawidwa m'magawo otsatirawa:
1.Kutsuka ndi alkali: mapaipi ena achitsulo ali ndi madontho a mafuta pamwamba, kotero kutsuka ndi alkali ndikofunikira.
2.Kusankha: hydrochloric acid imasankhidwa kuti ichotse khungu la oxide pamwamba pa chitoliro chachitsulo.
3.Kutsuka: makamaka kuchotsa asidi wotsala ndi mchere wachitsulo womwe walumikizidwa pamwamba pa chitoliro chachitsulo.
4.Zothandizira kuviika: ntchito ya flux ndikuchotsa zonyansa zonse pamwamba pa chitoliro chachitsulo, kuonetsetsa kuti chitoliro chachitsulo ndi yankho la zinc zikulumikizana bwino, ndikupanga chophimba chabwino.
5.Kuumitsa: makamaka pofuna kupewa kuti chitoliro chachitsulo chisalowe mu mphika wa zinc ndi kuphulika.
6.Kutenthetsa madzi a zinc mu mphika wa zinc kuyenera kuyendetsedwa mosamala pa 450+5 ° C, chitoliro chachitsulo chiyenera kuyikidwa mu ng'anjo ya galvanizing ndikukulungidwa mu zingwe zitatu zoyezera zinc mu makina oyezera. Zingwe zitatuzi zili ndi magawo osiyanasiyana, zomwe zimapangitsa kuti chitoliro chachitsulo chikhale chopendekeka pa zingwezo. Ndi kuzungulira kwa zingwezo, chitoliro chachitsulo chimasunthira pansi mbali imodzi kuti chipange ngodya yopendekeka, kenako chimalowa mu bafa la zinc, chimapitiliza kuyenda pansi, ndikugwera pa njanji yotsetsereka mu mphika wa zinc; Chitoliro chachitsulo chikakwezedwa pamwamba pa kusakaniza kwa maginito, chidzakokedwa ndikusunthidwa ku njira yokoka gudumu.
7.Kupsa kwakunja: chitoliro chachitsulo chimadutsa mu mphete yakunja yopsa kuti chifinye mpweya ndikutulutsa madzi ochulukirapo a zinc kuchokera mu chitoliro chachitsulo kuti chiwoneke chosalala komanso choyera.
8.Kutulutsa zinc: Kuchuluka kwa zinc kumatha kulamulidwa ndipo kugwiritsa ntchito zinc kungachepe pochepetsa liwiro lotulutsa zinc moyenera.
9.Kupopera mkati: chotsani madzi ochulukirapo a zinc pamwamba pa chitoliro chachitsulo kuti mupeze malo osalala komanso oyera mkati. Madzi ochotsedwa a zinc amapanga ufa wa zinc kuti ubwezeretsedwenso.
10.Kuziziritsa madzi: kutentha kwa thanki yoziziritsira madzi kuyenera kulamulidwa pa 80 ℃, ndipo chitoliro chopangidwa ndi galvanized chiyenera kuziziritsidwa.
11.Kutulutsa mpweya woipa: yankho lotulutsa mpweya woipa limathiridwa pa chitoliro chomalizidwa cha mphete yopyoza kuti pamwamba pa chitolirocho pakhale mpweya woipa. Pambuyo pa mphete yopyoza yakunja, yankho lowonjezera lotulutsa mpweya woipa limachotsedwa ndi mpweya wopanikizika.
12.Kuyang'anira: chitoliro chachitsulo chopangidwa ndi galvanized chimagwera pa benchi yoyang'anira, chitoliro chopangidwa ndi galvanized chomwe chasowa chimayikidwa mu dengu la zinyalala, ndipo chitoliro chomalizidwa chimapakidwa ndikusungidwa.
