Ithangi Lokugcina Amanzi: Ukukhethwa Kwezinto Nokuklanywa Kwamanzi Ahlanzekile Nawokusetshenziswa
Ithangi lokugcina amanzi lingenye yezimpahla eziphila isikhathi eside kakhulu endaweni, kodwa ukukhethwa kwezinto zokwakha kuvame ukwenziwa ngezindleko zokuqala kuphela. Leso sinqumo sinquma ikhwalithi yamanzi, izabelomali zokunakekela kanye nemijikelezo yokushintsha eminyakeni engamashumi amathathu ezayo.
Ithangi lokugcina amanzi yisitsha esibamba amanzi okuphuza, amanzi okucubungula, amanzi okunisela noma amanzi okucisha umlilo ngaphansi kwezimo ezilawulwayo, akhiwe ngokwezindinganiso ezifana ne-AWWA D103 ne-NSF/ANSI 61. Amathangi ensimbi anamuhla ahlanganiswe ngamabhawodi anokupenda kwe-enamel noma i-epoxy okufakwe efektri ahlinzeka ngeminyaka engaphezu kwengu-30 yokusebenza kusukela ku-20 m³ kuya ku-60,000 m³.
Okufanele Ukuhlole Ngenkathi Ukhetha Ithangi Lokugcina Amanzi
Ukuvikelwa kwekhwalithi yamanzi: umsebenzi wamanzi okuphuza udinga izinto zokumboza eziqinisekisiwe nge-NSF/ANSI 61 noma i-WRAS, ezinobuso obungenzi lutho obungakhiphi izinto, obungonakalisi ukunambitheka, futhi obungasekeli ukukhula kwamagciwane.
Umthamo nendawo: amathangi ahlanganiswe ngamabhawodi akhula kusukela kumathangi epulazi angu-20 m³ kuya kumadamu omasipala angu-60,000 m³, futhi izilinganiso zobubanzi nobude zingalungiswa ngokuya ngezithiyo zendawo.
Izindleko zempilo yonke: ukufakwa kwe-fused coatings ekufeni kwefekthri kususa ukuphinda kufakwe emuva njalo ngeminyaka engu-8–12, izindleko ezifihlekile ezinkulu zensimbi ewelded kanye nokhonkolo.
Isimo sezulu kanye nemithwalo yokuzamazama komhlaba: ubunjiniyela be-AWWA D103 bubheka umoya, iqhwa, ukuzamazama komhlaba kanye nokushintsha kokushisa, okubalulekile ezakhiweni ezinde noma eziveziwe.
Yimaphi Amazinga Okuklama Alawula Amathangi Okugcina Amanzi?
AWWA D103-09: izinga elihamba phambili lesakhiwo samathangi ensimbi abolted afakwe i-coating ekufeni, elihlanganisa imithwalo yokuklama, ukwakhiwa kanye nokumiswa.
NSF/ANSI 61: izinga lemiphumela yezempilo lezinto ezithinta amanzi okuphuza; kucaciswe kunoma yiliphi ithangi elinikeza amanzi okuphuza.
I-ISO 28765: izinga le-enamel coating eliqinisekisa ikhwalithi ye-fused coating, ubukhulu, nokuhlolwa kwamathangi ensimbi angenwele zeglasi.
Amakhodi endawo: izindawo zokuzamazama komhlaba, ukuvikelwa emakhazeni, nezidingo zokufinyelela ophahleni ziyahlukahluka ngokwesifunda — ziqinisekise ngaphambi kokucaciswa kokugcina.
Indlela Ukukhethwa Kwezinto Okuthinta Ngayo Ukusebenza Kwethangi
Insimbi ye-GFS eboshelwe: uqweqwe oluncibilikisiwe ezinhlangothini zombili lumelana nokugqwala, lugcina amanzi ehlanzekile, futhi lufakwa ezinsukwini ezimbalwa ngethuluzi le-torque nekreni kuphela.
Insimbi egalvaniwe: iyonga izindleko emsebenzini owomile noma ongagqwali kakhulu, kodwa ukupasisha kwe-zinc nokulungiswa kokushisela kudinga ukuphathwa ngokucophelela.
Ukongkolo: ukuqina okuhlala isikhathi eside kodwa kuthambekele ekuqhekekeni nokuncika kwe-liner; ukulungisa kabusha kuyabiza futhi kuphazamisa.
I-HDPE ne-fiberglass: izinketho ezingasebenzi ngamakhemikhali emathangi amancane, ezikhawulelwe ukuzinza kwe-UV, amandla esakhiwo namandla amakhulu.

Noma iyiphi into ekhethiwe, ukucaciswa kufanele kusekelwe ekugqokweni okuqinisekisiwe, amazinga abhalwe phansi kanye nezindleko zokuphila konke kunenani lokuqala — iziyalo ezihlukanisa impahla yamanzi yeminyaka engu-30 enkingeni yeminyaka engu-10.
Imibuzo Ejwayelekile (FAQ)
UMBUZO 1: Uyini ithangi lokugcina amanzi?
Ithangi lokugcina amanzi umkhumbi owenzelwe ukubamba amanzi okuphuza, okucubungulwayo, okunisela noma omililo. Amathangi asezingeni elihle ahambisana ne-AWWA D103 (isakhiwo) kanye ne-NSF/ANSI 61 (ukuthintana namanzi okuphuza), ngokugqokwa kwe-GFS noma i-epoxy efakwe efektri ukuze ahlale iminyaka engu-30+.
UMBUZO 2: Iyiphi into engcono kakhulu yokugcina amanzi okuphuza?
Insimbi ye-GFS eboshelwe ene-NSF/ANSI 61 noma i-enamel eqinisekiswe yi-WRAS iyona ekhethwayo ehamba phambili: indawo engaguquki encibilikisiwe igcina ikhwalithi yamanzi, imelana nokugqwala futhi idinga ukunakekelwa okuncane kakhulu empilweni yeminyaka engu-30–40.
Umbuzo 3: Yiziphi izilinganiso zamathangi okugcina amanzi atholakalayo?
Amathangi ensimbi aboshelwe aqala ku-20 m³ kuya ku-60,000 m³, futhi amathangi amaningi angahlanganiswa ukuze akhe amadamu kamasipala. Ububanzi nokuphakama kulungiselelwa ngokwezidingo zendawo neze-hydraulic.
Umbuzo 4: Kungani ukhetha ithangi eliboshelwe kunelensimbi ewelisiwe noma likakhonkolo?
Ukwakhiwa okuboshelwe kwenziwa efektri, kuthunyelwe kufulekile futhi kumiswe ezinsukwini ezimbalwa ngaphandle kokushisela endaweni — kunciphisa isikhathi sokufaka, kugweme ukwehluleka kokufaka uqweqwe lokushisela, futhi kuvumela ukunwetshwa kwesikhathi esizayo ngokungeza amaringi.
