Kupisa-dip galvanized simbi pombi chinhu chakajairika chekuvakisa chine hunhu hwekupokana nekuora, kuramba kupfeka, uye hupenyu hurefu. Saka, hot-dip galvanized simbi pombi dzinogadzirwa sei?

1. Kugadzirira kwezvinhu zvakasvibirira: Chigadzirwa chikuru chekupisa-dip galvanized simbi pombi ndiyo yakajairika kabhoni simbi pombi. Munguva yekugadzira, iwe unofanirwa kutanga wasarudza yakakodzera simbi zvinhu uye uve nechokwadi chekuti hunhu hwayo hunosangana nezvinodiwa.

2. Steel pombi pretreatment: Isati inopisa-dip galvanizing, pombi yesimbi inoda kupinda munhevedzano ye pretreatment process. Kutanga, pombi yesimbi inonyungudutswa, uye ngura inobviswa kubvisa okisidhi, girisi, uye humwe hutsvina pamusoro. Zvadaro, chenesa pombi yesimbi kuti uone kuchena kwepamusoro. Izvi zvinokugadzirira iwe kune inotevera galvanizing maitiro.

3. Garavanizing process: Hot-dip galvanizing inzira iyo pombi dzesimbi dzinonyudzwa mumvura yakanyungudutswa yezinc kuti iite zinc layer pamusoro. Iyo chaiyo galvanizing process inosanganisira anotevera matanho:
a. Pickling: Iyo pretreated simbi pombi inonyudzwa mune asidhi mhinduro ye pickling kurapwa kubvisa oxides uye tsvina pamusoro. Iyi nhanho inobatsira kuvandudza kusungirirwa kwechigadziko chegalvanized pamusoro pepombi yesimbi.
b. Kunyura: Nyura pombi yesimbi yakanyungudutswa mune preheated ammonium chloride solution. Iyi nhanho inobatsira kubvisa okisidhi kubva pamusoro pepombi yesimbi uye inopa hwaro hwakanaka hwehunotevera hupfu.
c. Kuomesa: Tora pombi yesimbi yakanyoroveswa kubva mumushonga woiomesa kuti ubvise hunyoro pamusoro.
d. Preheating: Tumira pombi yesimbi yakaomeswa muchoto chekupisa chekurapa kwekupisa. Kudzora kwekushisa kwekupisa kwakakosha kune inotevera galvanizing maitiro.
e. Galvanizing: Dzvanya pombi yesimbi yakatsvairwa mumvura yakanyungudutswa yezinc. Mumvura ye zinc, simbi iri pamusoro pepombi yesimbi inopindirana ne zinc kuti iite zinc-iron alloy coating. Iyi nhanho inoda kudzora nguva yekubatisa uye tembiricha kuti ive nechokwadi chekufanana uye kunaka kwekuputira.
f. Kutonhodza: ​​Iyo galvanized simbi pombi inotorwa kunze kwemvura zinc uye yatonhodzwa. Chinangwa chekutonhora ndechekusimbisa kuvhara uye kuvandudza kunamatira kwayo.

4. Kuongorora uye kurongedza: Mapaipi esimbi ane galvanized anofanira kuongororwa kuti ave nechokwadi chokuti hutano hwavo hunosangana nemitemo yakakodzera. Izvo zvinyorwa zvekuongorora zvinosanganisira kutaridzika kwemhando, kukobvu kwekuputira, kunamatira, nezvimwewo. Mapaipi esimbi akakodzera achaiswa kuti adzivise kukanganisa panguva yekufambisa uye kushandiswa.

Iyo nzira yekugadzira inopisa-dip galvanized simbi mapaipi yakaoma uye inoda maitiro akawanda. Nekudaro, maitiro aya anogona kupa mapaipi esimbi ane yakanakisa anti-corrosion zvivakwa uye chitarisiko chakanaka, zvichiita kuti zvishandiswe zvakanyanya mukuvaka, kutakura, petrochemicals, uye mamwe minda.

Kupfupisa, maitiro ekugadzira anopisa-dip galvanized simbi pombi anosanganisira kugadzirira mbishi, simbi pombi pretreatment, galvanizing process, kuongorora, uye kurongedza. Kuburikidza nemaitiro aya matanho, hot-dip galvanized simbi mapaipi ane hunhu hwakavimbika anogona kugadzirwa kuti asangane nezvinodiwa zveakasiyana mainjiniya mapurojekiti. Kupisa-dip galvanized simbi pombi yave imwe yezvinhu zvakakosha mumunda wekuvaka nekuda kweakanakisa anti-corrosion zvivakwa uye kutaridzika kwakanaka. Mubudiriro yeramangwana, nekumwe kuvandudza nekuvandudza tekinoroji, nzira yekugadzira yepombi dzesimbi dzinopisa-dip dzicharamba dzichivandudzwa kuti dzipe mhinduro dziri nani dzekushandisa mune mamwe minda.
