Kupisa-dip galvanizing inzira yakajairika yekudzivirira ngura kwesimbi.Inonyudza zvigadzirwa zvesimbi mumvura yakanyungudutswa yezinc kuti iite zinc-iron alloy layer uye yakachena zinc layer pamusoro pesimbi, nokudaro ichipa yakanaka corrosion dziviriro.Iyi nzira inoshandiswa zvakanyanya mukuvaka, mota, simba, kutaurirana uye mamwe maindasitiri kuchengetedza simbi zvimiro, mapaipi, fasteners, nezvimwe.
Matanho ekutanga ekupisa-dip galvanizing process ndeaya anotevera:
Degreasing uye kuchenesa
Iyo simbi yepamusoro inoda kunyatsocheneswa kubvisa girisi, tsvina uye zvimwe tsvina.Izvi zvinowanzoitwa nekunyudza simbi mune alkaline kana acidic solution inoteverwa neinotonhora yekusuka.
Flux coating
Simbi yakacheneswa inobva yanyudzwa mu30% zinc ammonium solution pa65-80.°C.Chinangwa chenhanho iyi ndechekuisa mutsetse we flux kubatsira kubvisa okisidhi kubva pamusoro pesimbi uye kuve nechokwadi chekuti zinc yakanyungudutswa inogona kuita zvirinani nesimbi.
Galvanizing
Simbi inonyudzwa muzinc yakanyungudutswa patembiricha ingangoita 450°C. Nguva yekunyudza inowanzova maminitsi 4-5, zvichienderana nehukuru uye inertia inopisa yesimbi.Munguva iyi, nzvimbo yesimbi inopindirana nekemikari yakanyungudutswa zinc.
Kutonhora
Mushure mekupisa-dip galvanizing, simbi inoda kutonhora.Kutonhora kwemhepo yakasikwa kana kukurumidza kutonhora nekudzima kunogona kusarudzwa, uye iyo chaiyo nzira inoenderana nezvinodiwa zvekupedzisira zvechigadzirwa..
Kupisa-dip galvanizing inzira inoshanda yekudzivirira ngura yesimbi, inopa zvakakosha zvinobatsira:
●Mutengo wakaderera: Mari yekutanga uye yenguva refu yekupisa-dip galvanizing kazhinji yakaderera pane mamwe anti-corrosion coatings, zvichiita kuti ive sarudzo inokwanisika.
●Hupenyu hwesevhisi hwakareba kwazvo: Iyo yekubatisa marata inogona kuramba ichidzivirira simbi kweanopfuura makore makumi mashanu uye zvinobudirira kuramba ngura.
●Kuchengetedza kushoma kunodiwa: Sezvo galvanized coating ichizvichengetedza uye yakakora, ine yakaderera mari yekugadzirisa uye hupenyu hurefu hwebasa.
●Dzivirira otomatiki nzvimbo dzakakuvadzwa: Iyo yakavharidzirwa inovhara inopa dziviriro yechibairo, uye nzvimbo diki dzekukuvadzwa hadzidi kumwe kugadziriswa.
●Kudzivirirwa kwakazara uye kwakazara: Kupisa-dip galvanizing kunovimbisa kuti zvikamu zvese, kusanganisira zvakaoma-kusvika-nzvimbo, zvakachengetedzwa zvizere.
●Zviri nyore kuongorora: Mamiriro eiyo galvanized coating inogona kuongororwa nekureruka kwekuona kwekutarisa.
●Kuisa nekukurumidza:Zvigadzirwa zvekupisa-dip galvanized simbi zvakagadzirira kushandisa kana zvasvika panzvimbo yebasa, pasina kumwe kugadzirira kana kuongorora kunodiwa.
● Kukurumidza kushandiswa kwekuzara kwakazara: Iyo inopisa-dip galvanizing process inokurumidza uye haina kukanganiswa nemamiriro ekunze, kuve nechokwadi chekukurumidza kutendeuka.
Aya mabhenefiti anoita kupisa-dip galvanizing sarudzo yakanaka yekudzivirira ngura yesimbi, iyo isingangonatsiridza hupenyu hwesevhisi uye kuita kwesimbi, asi zvakare inoderedza mutengo wakazara uye basa rekugadzirisa.
Iyo yakafumurwa nzvimbo dzekupedzisira fittings (kusanganisira flange zviso) zveCDSR kusveta mafuta uye kuburitsa hosesanodzivirirwa nekupisa-kunyudza galvanizing zvinoenderana neEN ISO 1461 kubva mukuora kunokonzerwa nemvura yegungwa, mhute yemunyu uye nzira yekutapurirana.Sezvo indasitiri yemafuta negasi ichienderera mberi nekusimudzira budiriro, kushandiswa kweiyo inopisa-dip galvanizing tekinoroji haingonatsiridzire kushora kwemidziyo uye kuwedzera hupenyu hwayo hwesevhisi, asi zvakare inoderedza zvisina kunanga kushandiswa kwezviwanikwa uye kugadzirwa kwemarara nekudzikisa kuwanda kwekutsiviwa kwemidziyo. nekuda kwekuora.
