Kupisa dipi kwakakurudzira simbi pombi, inozivikanwawo sehot dip galvanized pipe, inyere yesimbi iyo inorovererwa kune yakawanda simbi pombi kuti ivandudze kushanda kwayo kwebasa. Kugadziriswa kwayo uye nheyo yekugadzira ndeyekuita kuti simbi yakanyungudutswa iite nesimbi substrate kuti ibudise alloy layer, kuitira kuti substrate uye coating zvibatanidzwe. Makadiihot-dip galvanized steel pombiprocessed? Kuyerera kweiyo inopisa-dip galvanized simbi pombi yakakamurwa kuita zvinotevera matanho:
1.Alkali washing: mamwe mapaipi esimbi ane mafuta mavara pamusoro, saka kugeza alkali kunodiwa.
2.Pickling: hydrochloric acid inosarudzwa kuti ibvise kubvisa ganda re oxide pamusoro pesimbi pombi.
3.Rinsing: kunyanya kubvisa yakasara asidhi nesimbi munyu wakanamirwa nesimbi pombi pamusoro.
4.Dipping aids: basa rekuyerera nderokubvisa zvese zvakasvibiswa kubva pane simbi pombi pamusoro, kuve nechokwadi chekubatana kwakachena pakati pepombi yesimbi uye zinc mhinduro, uye kugadzira yakanatswa.
5.Kuomesa: kunyanya kudzivirira pombi yesimbi kuti isanyudzwe muhari ye zinc uye kuputika.
6.Kupisa dip galvanizing: tembiricha yezinc fluid mupoto yezingi ichanyatsodzorwa pa450+5 ° C, pombi yesimbi ichaiswa muchoto chinopfuta uye yakakungurutswa mumatatu matatu ekunyudza madhiri mumushini wegalvanizing. Zvitatu zvinotenderera zvine zvikamu zvakasiyana, zvichiita kuti pombi yesimbi irereke pamhepo. Nekutenderera kwemaspirals, pombi yesimbi inofamba ichidzika kune rumwe rutivi kuti iite kona yekurerekera, yobva yapinda mubhavhu rezinc, inoramba ichifamba ichidzika, uye inongoerekana yawira panjanji inotsvedza muhari ye zinc; Kana iyo pombi yesimbi inosimudzwa kune iyo magineti yekusanganisa pamusoro, inokwezvwa uye ichiendeswa kune inodhonza vhiri track.
7.Kufuridzira kunze: pombi yesimbi inopfuura nepakati pekunze inofuridza mhete kuti inomesa mweya uye ichibvisa yakawandisa zinc fluid kubva papombi yesimbi kuti iwane kutaridzika kwakanaka uye kwakachena.
8.Kudhonza kunze: Huwandu hwezinc hunogona kudzorwa uye kushandiswa kwezinc kunogona kudzikiswa nekudzikisira zvakafanira kumhanya kwekudhonza.
9.Kufuridza kwemukati: bvisa yakawandisa zinc fluid pane yemukati pepombi yesimbi kuti uwane yakatsetseka uye yakachena mukati. Iyo zinc fluid yakabviswa inoita zinc powder kuti idzokororwe zvakare.
10.Kutonhora kwemvura: tembiricha yetangi yekutonhodza yemvura inodzorwa pa80 ℃, uye pombi yakashongedzwa ichatonhodzwa.
11.Passivation: iyo passivation solution inopfapfaidzwa papombi yakapedzwa yemhete yekuridza kuita kuti pombi ipfuure. Mushure mekuridza mhete yekunze, iyo yakawandisa passivation mhinduro inopeperetswa nemhepo yakamanikidzwa.
12.Kuongorora: iyo galvanized simbi pombi inowira pabhenji rekuongorora, mushure mekuongorora, pombi yakashaikwa inoiswa mubhasiki remarara, uye pombi yakapedzwa inorongedzerwa uye inoiswa mudura.
