Iipali zezibane zesitalato zeHDG vs. Iipali zezibane zesitalato ezipeyintiweyo

Kwiiprojekthi zokukhanyisa ezitalatweni, inkqubo yokulwa nokugqwala kweepali zokukhanyisa imisela ngokuthe ngqo ubomi benkonzo yazo kunye nomgangatho weprojekthi. Kwimarike, kukhoiipali zezibane zesitalato ezifakwe ngentsimbi eshushukunye neepali zezibane zesitalato ezipeyintwe rhoqo. Ezi zimbini zahlukile kakhulu ngokwemigaqo yenkqubo, ukusebenza kokulwa nokugqwala, ubomi benkonzo, iimeko ezifanelekileyo kunye neendleko zeprojekthi. Ukukhetha inkqubo engalunganga yeyona nto iphambili yeengxaki ezininzi zokulungiswa ngokutsha kunye neengxaki zeepali zezibane ezigqwalileyo nezixobukayo. Masifunde ngakumbi ngale nto ngomatshini wezibane zesitalato uTianxiang.

I. Umahluko kwiindlela zeMveliso

Iipali zokukhanya eziqhelekileyo ezipeyintwe zicutshungulwa ngokugquma okubonakalayo okungaphezulu, apho ipali ipholishwa ize itshizwe ngomaleko wepeyinti yokulwa nomhlwa kunye ne-topcoat. Ipeyinti igquma kuphela umphezulu wombhobho kwaye ayinakungena ngaphakathi kwentsimbi, ngoko ke ii-welds kunye neekona ezifileyo kulula ukuzigquma kakubi. Nangona kunjalo, iipali zokukhanya zesitalato ze-HDG zisebenzisa inkqubo ye-chemical hot-dip galvanizing. Ipali yokukhanya egqityiweyo ifakwa kwitanki ye-zinc enyibilikisiweyo kubushushu obuphezulu. Umaleko we-zinc ubopha ngentsimbi ngentsimbi. Udonga lonke lwangaphakathi nolwangaphandle, ii-welds kunye nezikhewu zigqunywe ngokupheleleyo yi-zinc, eqinisekisa ukugquma okupheleleyo ngaphandle kweekona ezifileyo. Umgangatho wenkqubo ungcono kakhulu kuneepali ezipeyintweyo.

II. Umahluko kwiNgxaki yokuGqobhoka kunye neNgxaki yokuGqobhoka kweMozulu

Akukho kunamathelana kakuhle kwepeyinti kwiipali zokukhanya ezipeyintiweyo, nto leyo ebangela ukuqhekeka, ukuxobuka nokunyamalala emva kokuba umoya nelanga livutha. Ukungena komswakama kukhokelela ekugrumbeni ngokukhawuleza nasekugrumbeni, ngakumbi kwiindawo ezinemvula, ezinomoya, ezinesanti kunye neziselunxwemeni. Umhlwa unokuvela kwisithuba seenyanga ezintandathu ukuya kunyaka. Iipali zokukhanya kwesitalato ezifakwe igesi ezishushu zinamathele kakuhle kwi-zinc coating kwaye zimelana nokuziphilisa. Iimpembelelo ezincinci aziyi kubangela ukuxobuka okukhulu. Azinamanzi, azina-oxidation, azina-asidi kunye ne-alkali, azina-typhoon, azina-zimvula ezinkulu kunye namaqondo obushushu aphezulu, kwaye zinokumelana nokugrumbuka okuzinzileyo.

III. Umahluko kwiindleko zoBomi beNkonzo kunye noLondolozo

Iipali zezibane zesitalato ezipeyintwe rhoqo zineminyaka emi-2-3 kuphela, ekufuneka zipeyintwe kwaye zihlaziywe rhoqo, ngeendleko eziphezulu zokugcinwa kwexesha elide, kwaye zichaphazela isiphumo sokukhanyisa kwesixeko. Iipali zezibane zesitalato ezifakwe i-hot-dip azinakugcinwa kwaye zihlala iminyaka eli-15-20 phantsi kokusetyenziswa okuqhelekileyo ngaphandle. Ingubo ayigugi kwaye ayixobuli kwaye izinzile ixesha elide emva kokufakwa, nto leyo enciphisa kakhulu iindleko zomsebenzi kunye nezixhobo zokulungisa nokutshintsha, nto leyo ebonelela ngeendleko ezingcono.

IV. Umahluko kwiMigangatho yoBunjineli eSebenzayo

Iipali zokukhanya eziqhelekileyo ezipeyintiweyo zisebenza kuphela ekukhanyiseni okwethutyana nasekusetyenzisweni kwexesha elifutshane ebaleni, azikwazi ukuhlangabezana nemigangatho yomasipala, ukuvuselelwa kwamaphandle kunye nokusetyenziswa kwexesha elide kweeprojekthi zangaphandle. Iipali zokukhanya zesitalato ze-HDG, ezihlangabezana nemigangatho yobunjineli besizwe, kwaye zikhetho lokuqala kwiiprojekthi zangaphandle zexesha elide ezifana neendlela zikamasipala, izibane ezintsha zasemaphandleni, iindawo ezintle, iindawo zeentaba eziselunxwemeni kunye neepaki zoshishino, ezinokhuseleko oluphezulu, uzinzo kunye nokubambelela.

I-Tianxiang yinkampani edumileyo yokuvelisa izibane zasezitalatweni, egxile ekuveliseni iipali zezibane zasezitalatweni ezishushu nezifakwe i-hot-dip ezikumgangatho ophezulu, isebenzisa inkqubo ye-hot dip galvanizing esemgangathweni kazwelonke.Ipali yesibane sesitalato se-HDGigqunywe ngokupheleleyo, akukho kona ifileyo, ayinamatheli, ayixobuki, ayiqhekeki. Iipali ziqinile kwaye zinamandla, azinamoya, azinaxinzelelo, azina-asidi kwaye azina-alkali kwaye azinamhlwa, azichaphazeleki yimvula, ikhephu, isivuthuvuthu okanye indawo yokutshiza ityuwa elunxwemeni. Akukho mfuneko yokugcinwa emva kokulungiswa, kwaye ubomi benkonzo bude kakhulu kunobo beepali zokukhanya eziqhelekileyo ezipeyintiweyo. Sinikezela ngoluhlu olupheleleyo lweenkcazo kunye nokwenza ngokwezifiso, ezenzelwe iiprojekthi zokukhanyisa zikamasipala nezasemaphandleni, ngomgangatho othembekileyo.
