Hot dip galvanizinginzira inoshandiswa zvakanyanya yekudzivirira simbi kubva mukuora.Maitiro acho anosanganisira akati wandei matanho akakosha, anosanganisira pre-kurapwa, izvo zvakakosha pakuona kunaka uye kusimba kweiyo galvanized coating.Chinhu chakakosha chekurapa kusati kwaitwa ndiko kushandiswa kwematangi ekudzikisa pamwe nekudziya kuti igadzirire iyo galvanizing process.
Nhanho yekutanga mukupisa-dip galvanizing process ndeyepretreatment, iyo inosanganisira kuchenesa simbi kuti ibvise chero tsvina inogona kuvhiringidza nzira yekugadzira galvanizing.Izvi zvinowanzoitwa mune tangi yekudzikisa, uko simbi inonyudzwa mune inopisa alkaline mhinduro kubvisa mafuta, mafuta kana mamwe masara ehupenyu kubva pamusoro.Iyo degreasing tank chikamu chakakosha cheiyopre-kurapa maitirosezvo inoita kuti simbi yacho inyatsocheneswa isati yaiswa marata.
Kana imwe nguva simbi yacheneswa mu tangi degreasing, zvinogona kuvapre-heated.Iyi nhanho inosanganisira kudziyisa simbi kubvisa chero hunyoro hwasara uye kugadzirira pamusoro pekuita galvanizing process.Kupisa simbi kwakakosha sezvo kunobatsira kuve nechokwadi chekuti galvanized coating inonamatira kumusoro zvakanaka, zvichiita kuti igare yakasimba uye inogara kwenguva refu.
Kana matanho ekutanga ekurapa apera, simbi yakagadzirirainopisa-dip galvanizingprocess.Izvi zvinosanganisira kunyudza simbi yacho mubhavhu rezinc yakanyungudutswa, iyo inosungirirana nesimbi kusimbi kuti iumbe rinodzivirira risingaparare zvakanyanya.Iyo galvanizing process inoitika pakupisa kwepamusoro, kazhinji kutenderedza 450 ° C (850 ° F), kuve nechokwadi chekuti zinc yekuputira zvisungo zvinosungirira kusimbi.
Mushure mekunge simbi yave nemarara, inotonhodzwa uye inoongororwa kuti ione kuti kupfekedza kwakafanana uye kusina kukanganisa.Yakawandisa zinc inobviswa, uye simbi inozogadzirira kune dzakasiyana siyana dzekushandisa, kubva pakuvaka uye zvivakwa kusvika kumotokari uye zvigadzirwa zvemaindasitiri.
Kupfupisa, iyo inopisa-dip galvanizing process inosanganisira akati wandei matanho akakosha, kusanganisirapre-kurapwa inopisa-dip galvanizing, kushandiswa kwematangi ekubvisa mafuta, uye kupisa kusati kwaitwa.Aya matanho anokosha kuti ave nechokwadi chokuti simbi yakanyatsogadzirirwa nzira yekugadzira galvanizing, zvichiita kuti pave nepamusoro-soro, yekugara kwenguva refu iyo inopa kudzivirirwa kwakanakisisa kubva pakuora.Nekutevera matanho aya, vagadziri vanogona kuve nechokwadi chekuti zvigadzirwa zvavo zvesimbi zvinosangana nemhando yepamusoro uye maitiro ekuita.
