Mapaipi esimbi ane galvanized akakamurwa kuita pombi dzesimbi dzinotonhora-dhip uye pombi dzesimbi dzinopisa.Mapombi ane galvanized anowanzo shandiswa pamvura, gasi, oiri uye mamwe akajairwa akakwira-kudzvanywa kwemvura mapaipi.Iwo anoshandiswawo muindasitiri yeparafini, kunyanya mapaipi emunda wemafuta muminda yemafuta ekumahombekombe, zvinotonhorera, pombi dzekuchinjana marasha uye mapaipi epabhiriji, mapaipi ekutsigira mugodhi, nezvimwe.

Zvinonzi galvanized simbi pombi inoshandiswa gasi uye kudziyisa.Sepombi yemvura, shoma shoma yemarara ichawanikwa mushure memakore mashomanana.Haisi kungosvibisa hutsanana chete, asiwo mabhakitiriya anokura pamadziro emukati wepombi.Ngura inokonzeresa simbi yakakwira mumuviri wemvura uye inoisa hutano hwevanhu panjodzi.
Kupisa dip galvanizing ndiko kunyudza pombi yesimbi muasidhi yekugezesa, uye kugadzira mvura ine mvura ine ammonium chloride aqueous solution kana zinc chloride uye zinc chloride, woidira mugorofu.Kupisa dip galvanized coating iyunifomu, ine kunamatira kwakasimba uye hupenyu hurefu hwebasa.Iyo matrix yekupisa-dip galvanized simbi pombi yakaoma yemuviri uye yakanyungudutswa ye electroplating mhinduro, saka kemikari inogadzirisa inoumba compact dhizaini uye kusagadzikana kwekuora.Iyo alloy layer inosanganiswa neiyo yakachena zinc layer uye simbi pombi base, saka ine yakasimba corrosion resistance.
Cold galvanized pipe is electro galvanized, uye pane mutsauko mukuru pakati pekupokana necorrosion resistance uye hot-dip galvanized pipe.Kuti ive nechokwadi chemhando, vazhinji vanogadzira galvanizing manejimendi vanogadzira havashandise electro galvanizing (kutonhora plating).Aya mabhizinesi madiki asina kurongeka achashandisa electro galvanizing nekuti mutengo wakachipa.Iyo galvanized layer yechando-dip galvanized simbi pombi ndeyekuputira.Iyo zinc layer yakaturikidzana yakazvimirira nesimbi pombi matrix.Iyo zinc layer yakatetepa, iyo inongobatanidzwa kune simbi pombi uye nyore kudonha.Naizvozvo, kushorwa kwaro kwakashata.Naizvozvo, kune mamwe mapaipi akavigwa zvakananga, mapaipi esimbi esimbi anogadzirwa nevagadziri venguva dzose achiri kutorwa.

Maitiro ekuwedzera kunatswa kwesimbi isina simbi kuburikidza nekuderedza kabhoni

Huwandu hwekabhoni musimbi isina tsvina hunofanirwa kunge hwakaderera pane huri musimbi yekabhoni kana simbi yakaderera (kureva, simbi ine alloying element iri pasi pe5%).Nepo magetsi arc furnaces (EAF) ari iwo akajairwa nzira yekunyungudusa nekunatsa simbi isina tsvina, AOD ndeyekuwedzera kwehupfumi, sezvo nguva yekushanda ipfupi uye tembiricha yakadzikira pane muEAF kugadzira simbi.Pamusoro pezvo, kushandisa AOD yekunatsa simbi isina tsvina kunowedzera kuwanikwa kweEAF nekuda kwekunyunguduka.

Simbi yakanyungudutswa, isina kucheneswa inotamiswa kubva muEAF ichiiswa mumudziyo wakasiyana.Musanganiswa weargon uye okisijeni inoputika kubva pasi pemudziyo kuburikidza nesimbi yakanyunguduka.Vagadziri vekuchenesa vanowedzerwa kumudziyo pamwe chete nemagasi aya kuti abvise tsvina, nepo okisijeni inosanganiswa nekabhoni musimbi isina kucheneswa kuderedza carbon level.Kuvapo kweargon kunowedzera kuwirirana kwekabhoni yeokisijeni uye nokudaro kunobatsira kubvisa kabhoni.

Kuora kwesimbi yekugadzira inzira ye electrochemical inoda kuvepo panguva imwe chete yehunyoro uye oxygen.Kana pasina imwe, corrosion haiitike.Chaizvoizvo, simbi iri musimbi inoiswa oxidised kuburitsa ngura, iyo inotora kanenge katanhatu huwandu hwechinhu chepakutanga chinopedzwa mukuita.The general corrosion process inoratidzwa pano.Pamwe chete ne general corrosion, kune marudzi akasiyana-siyana ekuora kwenzvimbo anogona kuitikawo;bimetallic corrosion, pitting corrosion uye crevice corrosion.Zvisineyi, izvi zvinenge zvisinganyanyi kukosha pakugadzirwa kwesimbi.
