Kwizixeko ezikunxweme nakwiindawo ezinomswakama ophezulu, ukuqina kwenkqubo yokukhupha amanzi kunxulumene ngokuthe ngqo nokhuseleko kunye neendleko zokusebenza kunye nokugcinwa kweziseko zophuhliso zasezidolophini. Izixeko eziqhelekileyo ezikunxweme ezifana neHong Kong neSingapore zijongene nokukhukuliseka komoya onetyuwa eninzi kunye nemozulu efumileyo unyaka wonke. Imibhobho yokukhupha amanzi yesinyithi yendabuko isengozini yokuvuza kunye nomonakalo ngenxa yokugqwala, kwaye inokubangela ungcoliseko lokusingqongileyo kunye neengozi ezifihlakeleyo kwizakhiwo. Ukuphendula eli nqaku lentlungu,I-DINSENiqalise imveliso entsha – imibhobho yokukhupha amanzi yesinyithi etshiziweyo nge-zinc, echaza ngokutsha izisombululo zoshishino ngeenkqubo ezintsha kunye nokusebenza okusemgangathweni ophezulu.
Indalo esingqongileyo eselunxwemeni iyingozi kakhulu kwiipayipi zesinyithi kuneendawo zangaphakathi. Ii-ion ze-chloride kwi-salt spray zidibana nokufuma emoyeni ukukhawulezisa i-oxidation yesinyithi, nto leyo ebangela ukuba umaleko we-zinc kumphezulu weepayipi ze-galvanized zemveli uwe ngokukhawuleza, kwaye ekugqibeleni ubangele ukubola komzimba wepayipi. Ukongeza, utshintsho oluqhelekileyo lobushushu kunye nemitha ye-ultraviolet nazo ziya kwenza kube nzima ukuguga kwengubo. Iitekhnoloji zemveli zokulwa nokubola (ezifana ne-galvanizing eqhelekileyo okanye ukupeyinta) kunzima ukugcina iziphumo zokhuseleko lwexesha elide kwiimeko zemozulu ezinzima. Ukutshintshwa rhoqo kweepayipi akupheleli nje ekunyuseni iindleko, kodwa kukwachaphazela nokusebenza okuqhelekileyo kwesixeko.
Ixesha lokulwa nokugqwala le-zinc etshizwa ngobushushu liphezulu ngokuphindwe kayi-4-10 kunelentsimbi enganyangwanga.Umahluko othile uxhomekeke kwinqanaba lokusingqongileyo kunye nemigangatho yenkqubo. Phantsi kweemeko zokwakha eziqhelekileyo, i-zinc etshizwa ngobushushu inokubonelela ngokhuseleko lwexesha elide iminyaka engaphezu kwama-20, ngelixa intsimbi enganyangwanga inokuhlala iminyaka emi-3-5 kuphela phantsi kwendawo efanayo. Lo mfanekiso ulandelayo uthelekiso oluthe ngqo lwemibhobho yesinyithi etshizwa ngo-zinc kunye ne-non-zinc-sprayed. Icala lasekhohlo ngumbhobho wesinyithi otshizwa ngo-zinc (DN50 EN877:2021 A1 Z), kwaye icala lasekunene ngumbhobho wesinyithi oqhelekileyo.
Ukusebenza kwale nkqubo yokulwa nokugqwala kuphumelele uvavanyo oluqatha lomgangatho we-EN877 (kubandakanyauvavanyo lokutshiza ityuwa, uvavanyo lokugqwala olujikelezayo, njl.njl.).I-EN877 ngumgangatho ogunyazisiweyo wesatifikethi kwicandelo lemibhobho yokukhupha amanzi ngesinyithi eYurophu, ebeka phambili iimfuno ezicwangcisiweyo zeempawu zoomatshini, ukuvala kunye nokukwazi ukulwa nokugqwala kwemibhobho.Iipayipi zesinyithi ezitshizwe nge-zinc ze-DINSEN zifanelekile kwizakhiwo eziphakamileyo, kwiipaseji zepayipi ezihlanganisiweyo ezingaphantsi komhlaba nakwezinye iindawo apho ukwakhiwa rhoqo kunzima.Ziyahambelana ngokupheleleyo nomgangatho we-EN877 kwaye zithandwa kakhulu ngabathengi abakumgangatho ophezulu ngenxa yeenzuzo zazo zokulwa nokugqwala.
Okwangoku, le mveliso isetyenziswe ngempumelelo kwizakhiwo ezininzi ezibalulekileyo eHong Kong (ezifana neendawo zorhwebo kunye neeprojekthi zokwandiswa kwezikhululo zeenqwelo moya), kwaye inyuswe kancinci kancinci kwiindawo ezikunxweme ezifana noMzantsi-mpuma we-Asia kunye noMbindi Mpuma. Ixabiso layo alibonakali kuphela ekusebenzeni kwayo kobugcisa, kodwa likwabonakala nakwimisebenzi yayo yobugcisa.ifumana ukuthandwa ngabathengi ngenxa yenzuzo yayo epheleleyo yeendleko zomjikelo wobomi – nangona utyalo-mali lokuqala luphezulu kancinci kunolo lweepayipi eziqhelekileyo, iimpawu zayo zokungasebenzisi monakalo ixesha elide zinokunciphisa iindleko zizonke ngaphezulu kwama-30%.
Phantsi koxinzelelo oluphindwe kabini lokufudukela kwabantu ezidolophini kunye notshintsho lwemozulu, "umgca wokhuselo ongabonakaliyo" weziseko zophuhliso kufuneka uphuculwe ngokukhawuleza. Ngobuchwepheshe bayo obutsha bokulwa nokugqwala kunye nesatifikethi esisemgangathweni ophezulu, imibhobho yesinyithi esitshiziweyo se-DINSEN inika izixeko eziselunxwemeni izisombululo zokuhambisa amanzi ezithembekileyo nezizinzileyo. Kwixesha elizayo, njengoko imfuno yehlabathi yezixeko ezizinzileyo isanda, obu buchwepheshe bunokuphinda buchaze umgangatho weshishini kwaye bukhuthaze utshintsho lwemibhobho yesinyithi esitshiziweyo ukusuka "kwiindawo ezisebenzayo" ukuya "kwiindawo zexabiso".
