Kana zvasvika kune inopisa yakanyudzwa galvanized simbi pombi, maitiro ekupisa-dip galvanizing anoguma mune metallurgical bond pakati pe zinc nesimbi ine nhevedzano yeakasiyana iron-zinc alloys. Yakajairika hot-dip galvanizing line inoshanda seinotevera:
◆Simbi inocheneswa pachishandiswa mushonga unokonzeresa. Izvi zvinobvisa mafuta/girisi, tsvina, uye pendi.
◆ Mushonga wekuchenesa unosukwa.
◆Simbi inobikwa muacidic solution kubvisa chigayo.
◆ Mushonga we pickling unosukwa.
◆A flux, kazhinji zinc ammonium chloride inoshandiswa kusimbi kuti inhibit oxidation yenzvimbo yakacheneswa kana yasangana nemhepo. Iyo flux inobvumirwa kuomeswa pasimbi uye inobatsira mukuita kwemvura zinc wetting uye kunamatira kune simbi.
◆Simbi inonyikwa mubath yakanyungudutswa yezinc yochengetwamo kusvikira tembiricha yesimbi yaenzana neyekugezera.
Neunyanzvi, galvanization inzira yekunamira simbi nesimbi nedariro rezingi nekunyudza simbi mubhavhu rezinc yakanyungudutswa patembiricha inosvika 840 °F (449 °C). Kana yaiswa mumhepo, zinc yakachena (Zn) inopindirana neokisijeni (O2) kuumba zinc oxide (ZnO), iyo inowedzera kuita necarbon dioxide (CO2) kuumba zinc carbonate (ZnCO3), inowanzoita grey, yakasimba. zvinhu zvinodzivirira simbi iri pasi kubva pakuwedzera ngura mumamiriro mazhinji. Kazhinji, pombi inopisa yakanyudzwa yakanyungudutswa ine mutengo wepombi yesimbi yakakwira kupfuura mamwe marudzi akajairwa epombi ari kushandiswa nekuda kwemutengo wayo wepamusoro wekugadzira pamusika.
Pamashandisirwo anoshanda, semamwe masisitimu ekudzivirira ngura, galvanizing inonyanya kuchengetedza zvigadzirwa zvesimbi nekuita sechivharo pakati pesimbi nemhepo. Zvisinei, zingi isimbi yakawanda yemagetsi kana ichienzaniswa nesimbi. Ichi chimiro chakasiyana chekugadzira galvanizing. Kunyanya, kana galvanized coating ikakuvadzwa uye chigadzirwa chesimbi chaiswa mumhepo, zinc inogona kuramba ichidzivirira simbi kuburikidza ne galvanic corrosion. Kunze kwezvo, nekuda kwekugara kwayo uye anti-corrosive zvivakwa, akawanda eanotonhora akakungurutswa simbi pombi anogona kudzokororwa uye kushandiswazve, izvo kune imwe nhanho inochengetedza mari yakawanda panguva yebasa rekugadzirisa.
Nechidziviriro chekudzivirira, mapaipi anogona kushandiswa munzvimbo dzekunze, uye anogona kumira kukuvadza kubva kune mamwe maitiro ezvakatipoteredza. Kuyedzwa uye zvidzidzo zvakaratidza kuti avhareji yehupenyu hwekutarisira simbi yakabatiswa inoshandiswa seyakajairwa chigadziriso zvinhu inodarika makore makumi mashanu munzvimbo yekumaruwa uye 20-25 makore kana kupfuura munzvimbo yakanyanyisa yedhorobha kana yemahombekombe. Panyaya iyi, makondirakiti anogona kushandisa chigadzirwa ichi nechivimbo muprojekiti. Senyanzvi yekugadzira pombi yesimbi muChina, takazvipira kugadzira marudzi akasiyana-siyana epombi yesimbi yemapurojekiti ako. Kuti uwane rumwe ruzivo, unogona kutibata chero nguva.
