Emadolobheni asogwini nasezindaweni ezinomswakama ophezulu, ukuqina kohlelo lokukhipha amanzi kuhlobene ngqo nokuphepha kanye nezindleko zokusebenza kanye nokugcinwa kwengqalasizinda yasemadolobheni. Amadolobha avamile asogwini njengeHong Kong neSingapore abhekene nokuguguleka komoya ogcwele usawoti kanye nesimo sezulu esinomswakama unyaka wonke. Amapayipi okukhipha amanzi ensimbi avamile avame ukuvuza kanye nomonakalo ngenxa yokugqwala, futhi abangele ngisho nokungcola kwemvelo kanye nezingozi ezifihliwe ezakhiweni zezakhiwo. Ukuphendula leli phuzu elibuhlungu,I-DINSENuqalise umkhiqizo oguqukayo - amapayipi okukhipha amanzi ensimbi afuthwe nge-zinc, achaza kabusha izixazululo zemboni ngezinqubo ezintsha kanye nokusebenza okujwayelekile.
Indawo ezungezile ugu ingcolisa kakhulu amapayipi ensimbi kunezindawo zangaphakathi. Ama-ion e-chloride ku-salt spray ahlangana nomswakama emoyeni ukusheshisa i-oxidation yensimbi, okwenza ungqimba lwe-zinc ebusweni bamapayipi endabuko agqitshwe nge-galvanized luwe ngokushesha, futhi ekugcineni lubangele ukugqwala komzimba wepayipi. Ngaphezu kwalokho, izinguquko zokushisa ezivamile kanye nemisebe ye-ultraviolet kuzokwandisa ukuguga kwengubo. Ubuchwepheshe bendabuko bokulwa nokugqwala (njengokugqwala okuvamile noma ukupenda) kunzima ukugcina imiphumela yokuvikela yesikhathi eside ezimweni eziyinkimbinkimbi. Ukushintsha njalo amapayipi akugcini nje ngokukhuphula izindleko, kodwa futhi kuthinta nokusebenza okuvamile kwedolobha.
Isikhathi sokulwa nokugqwala se-zinc efuthwe ngokushisa siphakeme ngokuphindwe ka-4-10 kunesensimbi engalungiswanga.Umehluko othize uncike ezingeni lemvelo kanye nezindinganiso zenqubo. Ngaphansi kwezimo zokwakha ezijwayelekile, i-zinc efuthwe ngokushisa ingahlinzeka ngesivikelo sesikhathi eside iminyaka engaphezu kwengu-20, kuyilapho insimbi engaphathwanga ingahlala iminyaka engu-3-5 kuphela ngaphansi kwendawo efanayo. Lesi sibalo esilandelayo siwukuqhathaniswa okuqondile kwamapayipi ensimbi afuthwe nge-zinc kanye nalawo angafuthwanga nge-zinc. Uhlangothi lwesobunxele luyipayipi lensimbi elifuthwe nge-zinc (DN50 EN877:2021 A1 Z), kanti uhlangothi lwesokudla luyipayipi lensimbi elijwayelekile elifuthwe nge-zinc.
Ukusebenza kokulwa nokugqwala kwale nqubo kudlule izivivinyo ezinzima ze-EN877 standard (kufaka phakathiukuhlolwa kwesifutho sikasawoti, ukuhlolwa kokugqwala okujikelezayo, njll.).I-EN877 iyindinganiso yesitifiketi enegunya emkhakheni wamapayipi okukhipha amanzi ensimbi eYurophu, ebeka phambili izidingo ezihlelekile zezakhiwo zemishini, ukuvala kanye nekhono lokulwa nokugqwala kwamapayipi.Amapayipi ensimbi afakwe i-zinc afuthwa yi-DINSEN afanelekela izakhiwo eziphakeme, imihubhe yamapayipi ahlanganisiwe angaphansi komhlaba kanye nezinye izindawo lapho ukwakhiwa okuvamile kunzima khona.Zihambisana ngokugcwele nezinga le-EN877 futhi zithandwa kakhulu ngamakhasimende asezingeni eliphezulu ngenxa yezinzuzo zazo zokulwa nokugqwala.
Njengamanje, lo mkhiqizo usetshenziswe ngempumelelo ezakhiweni eziningi eziphawulekayo eHong Kong (njengezindawo zezentengiselwano kanye namaphrojekthi okwandisa isikhumulo sezindiza), futhi kancane kancane ukhushulelwe ezindaweni ezisogwini njengaseNingizimu-mpumalanga ye-Asia kanye neMpumalanga Ephakathi. Inani lawo alibonakali nje kuphela ekusebenzeni kwawo kobuchwepheshe, kodwa futhiithola ukuthandwa ngamakhasimende ngokusebenzisa inzuzo yayo yezindleko zomjikelezo wokuphila – yize ukutshalwa kwezimali kokuqala kuphakeme kancane kunokwamapayipi avamile, izici zayo zokungabi nokugcinwa kwesikhathi eside zinganciphisa izindleko zizonke ngaphezu kuka-30%.
Ngaphansi kwezingcindezi ezimbili zokukhula kwamadolobha kanye nokushintsha kwesimo sezulu, "umugqa wokuzivikela ongabonakali" wengqalasizinda udinga ukuthuthukiswa ngokushesha. Ngobuchwepheshe bayo obusha bokulwa nokugqwala kanye nesitifiketi esisezingeni eliphezulu, amapayipi ensimbi afakwe i-DINSEN ahlinzeka amadolobha asogwini ngezixazululo zokudonsa amanzi ezinokwethenjelwa neziqhubekayo. Esikhathini esizayo, njengoba isidingo somhlaba wonke samadolobha aqinile sanda, lobu buchwepheshe bungachaza kabusha izinga lomkhakha futhi bukhuthaze ukuguquka kwamapayipi ensimbi afakwe insimbi esuka "ezingxenyeni ezisebenzayo" iye "ezingxenyeni zenani".
