Ishiti elenziwe ngesinyithi libhekisa kwipleyiti yentsimbi eshinyeneyo enomaleko we-zinc obekwe phezu komhlaba.I-Hot-dip galvanizing yindlela yonyango eyongayo nesengqiqweni yokuchasa umhlwa esoloko ikhethwa.Malunga nesiqingatha semveliso yezinki yehlabathi isetyenziswa kule nkqubo.
Ishiti legalvanized kukuphepha ukubola kumphezulu wepleyiti yentsimbi eshinyeneyo kunye nokwandisa ubomi bayo benkonzo.Umphezulu wepleyiti yentsimbi eshinyeneyo uqatywe ngomaleko wentsimbi ye-zinc.Olu hlobo lwepleyiti yentsimbi ejiyileyo eqatywe ngezinki ibizwa ngokuba liphepha elenziwe ngamalenki.
Ngokweendlela zokuvelisa kunye nokucubungula, inokwahlulwa ngokwezi ndidi zilandelayo:
① Ipleyiti yentsimbi eshinyeneyo idiphu eshushu.Ishidi lensimbi epholileyo lifakwe kwi-bath zinc etyhidiweyo, ukwenzela ukuba umphezulu weshiti lensimbi epholileyo uhlanganiswe noluhlu lwezinc.Kweli nqanaba, isitshixo kukusebenzisa inkqubo eqhubekayo yokudibanisa i-hot-dip galvanizing yemveliso, oko kukuthi, ipleyiti yentsimbi eshinyeneyo epleyitini iqhubeka intywiliselwa kwitanki yokutshiza nge-zinc etyhidiweyo ukwenza i-galvanized sheet;
②Ishiti legalvanized eliqinisiweyo.Olu hlobo lwepleyiti yentsimbi eshinyeneyo lukwaveliswa yindlela yokudipha eshushu, kodwa ngoko nangoko emva kokuba iphumile etankini, ifudunyezwa malunga ne-500 ° C ukuyiguqula ibe yifilimu yeplastiki yealluminiyam ye-zinc kunye nentsimbi.Olu hlobo lwephepha le-galvanized linokunamathela ngokugqwesileyo kweengubo zezakhiwo kunye ne-welding yombane;
③ Iphepha elenziwe nge-electro-galvanized.Ukuveliswa kolu hlobo lwephepha le-galvanized by electroplating lunenkqubo egqwesileyo yokusebenza.Nangona kunjalo, i-coating incinci, kwaye ukuxhathisa umhlwa akulunganga njengaleyo yeshiti elishushu-dip;
④Icala elinye kunye necala eliphindwe kabini legalvanized sheet.Iphepha elinye kunye namacala amabini, oko kukuthi, iimpahla ezishushu-diphu zifakwe igalvanized kwicala elinye kuphela.Ngokumalunga ne-welding yombane, ukutshiza, unyango oluchasene nomhlwa, imveliso kunye nokucubungula, njl.Ukuze ukhuphe isiphene se-zinc engagqunywanga kumacala omabini, kukho olunye uhlobo lwephepha elifakwe igalvanized eliqatywe nge-chromatographic zinc kwelinye icala, oko kukuthi, iphepha elinezinki ezinomahluko macala omabini;
⑤ I-aluminiyam ialloy, iphepha elihlanganisiweyo legalvanized.Yenziwe nge-zinc kunye nezinye izinto zetsimbi ezifana ne-aluminiyam, ilothe, i-zinc, njl.njl. ukwenza iialloyi ze-aluminiyam okanye iipleyiti zentsimbi ezishinyeneyo.Olu hlobo lwepleyiti yentsimbi eshinyeneyo luneempawu zonyango ezichasene nomhlwa kunye neempawu ezibalaseleyo zokutshiza;
Ukongeza kwezi zintlanu zingentla, kukwakho neshiti elenziwe ngesinyithi elimibalabala, ushicilelo lwempahla olutshiziweyo, iphepha elenziwe ngelaminethiweyo lepolyethylene njalo njalo.Kodwa kweli nqanaba, eyona ixhaphakileyo iseyishiti eshushu-dip.
Ipleyiti yensimbi engenastainless ligama eliqhelekileyo lentsimbi enganyangekiyo enganyangekiyo kwiasidi, ekwaziyo ukumelana nezinto ezibuthathaka ezifana nerhasi, umphunga, amanzi, okanye imigangatho yentsimbi eneempawu zentsimbi ebizwa ngokuba yipleyiti yentsimbi;ngelixa izinto ezikwaziyo ukumelana ne-solvent (i-asidi, i-alkali, ityuwa kunye nezinye i-organic chemical corrosion) ) amabakala entsimbi amisiweyo abizwa ngokuba ziintsimbi ezinganyangekiyo kwi-asidi.
Ngenxa yomahluko ekubunjweni kwezi zibini, ukuxhathisa kwe-corrosion yabo kwahlukile.Ngokuqhelekileyo, iipleyiti zensimbi ezingenasici azikwazi ukuxhathisa ukubola kwe-solvent, ngelixa iintsimbi ezinganyangekiyo kwi-asidi zineempawu zentsimbi.Igama elithi "ipleyiti yensimbi engenasici" ayibhekiseli nje kuphela kuhlobo lwepleyiti yensimbi engenasici, kodwa ikwabonisa iintlobo ezingaphezu kwe-100 zeepleyiti zensimbi ezingenasici eziveliswa ngokwamashishini.Ipleyiti nganye yensimbi engenasici ephuhlisiwe kwaye iyilwe iya kuba neempawu ezibalaseleyo kwinjongo yayo ekhethekileyo.Isitshixo sokuphumelela kukufumanisa ukusetyenziswa okuphambili kuqala, kwaye emva koko ibakala elifanelekileyo lentsimbi.Ngokuqhelekileyo kukho amabakala amathandathu kuphela ensimbi anxulumene nenjongo ephambili yesakhiwo sokwakha.Bonke bane-17-22% ye-chromium, kwaye amabakala amahle ensimbi nawo ane-nickel.Ukongeza i-molybdenum kuphucula ngakumbi ukubola komoya kwaye imelana kakhulu nomoya one-fluoride.
Ipleyiti yentsimbi engatyiwayo ibhekiselele kwintsimbi ekwaziyo ukumelana nezinto ezibuthathaka ezifana nerhasi, umphunga, namanzi, kunye nezinto ezibolileyo zekhemikhali ezonakalisayo ezifana neasidi, ialkali, netyuwa, ekwaziwa njengentsimbi engatyiwayo enganyangekiyo kwiasidi.Kwizinto ezithile ezisetyenziswayo, intsimbi ekwaziyo ukumelana nezinto ezirhabaxa ezibuthathaka idla ngokubizwa ngokuba yintsimbi engatyiwa, kwaye intsimbi ekwaziyo ukumelana nokutyiwa kwenyibiliki ibizwa ngokuba yintsimbi ekwaziyo ukumelana neasidi.Ngenxa yomahluko ekubunjweni kwawo phakathi kwezi zimbini, eyokuqala ayinyanzeli ukuba imelane ne-solvent corrosion, ngelixa eyokugqibela ingenabala.Ukumelana nokugqwala kwamacwecwe ensimbi engenasici kulele kwizinto ze-aluminium alloy eziqulethwe kwintsimbi.
