Galvanized coil

1.Hupenyu hwesevhisi hwakareba seigalvanized coil?
Hupenyu hwesevhisi hwekupisa galvanizing kazhinji hausi pasi pemakore gumi.
2.Chinangwa chikuru cheiinopisa dip galvanized sheet?
Mhinduro: hot dip galvanized sheet rinonyanya kushandiswa mukuvaka, midziyo yemumba, mota, michina, zvemagetsi, indasitiri yemwenje uye mamwe maindasitiri.
3.Ndedzipi mhando mbiri dzekupisa dip galvanizing maererano nenzira dzakasiyana dzekuisa?
Mhinduro: inogona kukamurwa kuva mhando mbiri: in-line annealing uye kunze kwemutsara annealing, iyo inonziwo kudzivirira gasi nzira uye flux nzira.
4.Ndeapi marudzi esimbi akajairika ekupisa-dip galvanized sheet?
Mhinduro: zvikamu zvechigadzirwa: general commodity coil (CQ), structural galvanized sheet (HSLA), yakadzika dhizaini inopisa galvanized sheet (DDQ), bika kuomesa inopisa galvanized sheet (BH), dual phase simbi (DP), TRIP simbi (phase shanduko induced plastiki simbi), nezvimwewo.
5.Ndeapi mafomu ekubatisa annealing vira?
Mhinduro: kune marudzi matatu echoto chakatwasuka, chakachinjika annealing choto uye yakatwasuka uye yakachinjika annealing choto.
6.Ingani nzira dzekutonhodza dziripo dzeshongwe yekutonhodza?
Mhinduro: kune marudzi maviri: kutonhora kwemhepo uye kutonhora kwemvura.
7.Ndedzipi dzakanyanya kukanganisa kwekupisa dip galvanizing?
Mhinduro: inonyanya kusanganisira: kudonha, kukwenya, passivation spot, zinc particle, gobvu mupendero, air banga scratch, air banga scratch, pachena simbi, kusanganisirwa, kukuvara kwemagetsi, kusashanda zvakanaka kwesimbi base, wavy edge, scoop bend, saizi kusawirirana. , embossing, zinc layer ukobvu mismatch, roller kudhinda, nezvimwe.
8.Ndezvipi zvikonzero zvikuru zvekudonha kwe zinc layer?
Mhinduro: zvikonzero zvikuru zve zinc layer inowira pasi ndezvi: surface oxidation, silicon compounds, emulsion yakasviba yakawanda inotonhora, yakanyanyisa oxidation mhepo uye inodzivirira gasi dova muchikamu cheNOF, kusinganzwisisiki kwemhepo-mafuta ratio, kuderera kwehydrogen kuyerera, kupinza kweokisijeni muchoto, tembiricha yakaderera yesimbi yesimbi ichipinda mubhailer, yakaderera muchoto kudzvanywa muchikamu cheRWP uye kusveta kwemhepo pachoto. gonhi, tembiricha yakaderera muchoto muchikamu cheNOF, kusakwana kwemafuta evaporation, yakaderera aluminium zviri muhari yezinc, yakakurumidza kukurumidza unit, kusakwana kuderedzwa Nguva yekugara muzinc yakanyungudutswa ipfupi uye kupfekedza kwakanyanyisa.
9.Ndezvipi zvinokonzera ngura chena uye mavara matema?
Mhinduro: mavara matema anoumbwa nekuwedzera oxidation yewhite rust. Zvikonzero zvikuru zvewhite rust ndezvi:
Murombo passivation, kusakwana kana kusaenzana passivation firimu ukobvu; Iyo yepamusoro haina kuputirwa nemafuta kana mvura inoramba iri pamusoro pesimbi ye strip; Pane hunyoro pamusoro pebvisa simbipanguva yekuvhara; Passivation haina kuomeswa zvachose; Kunyorova kana kunaya panguva yekufambisa kana kuchengetedza; Nguva yekuchengetedza yezvigadzirwa zvakapedzwa yakarebesa; Iro galvanized sheet rinosangana nezvimwe zvinopisa media senge acid nealkali kana kuchengetwa pamwechete.
