Kwadalwa ngo Ngokwamukisa
Kungani i-NSF/ANSI 61 idingeka emathangini amanzi aphuzwayo?
Ithangi lamanzi aphuzwayo liyisisetshenziswa sezempilo yomphakathi, hhayi nje isitsha. Amanzi angahlala amahora noma izinsuku ngaphambi kokuba aphuzwe, futhi yonke into esetshenziswayo ethinta wona ingangena emanzini. Igobolondo lensimbi, ukuhlangana okuboshiwe, isivalo, i-coating kanye ne-liner ngakunye kungumthombo wokungcola. Ukucacisa ithangi ngekhodi yesakhiwo kuphela kushiya umbuzo wezempilo ungaphenduliwe, yingakho isitifiketi esihlukile semiphumela yezempilo siyimpoqo ezingxenyeni eziningi zomthetho.
I-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) ihlinzeka ngamathangi e-glass-fused-to-steel ane-coatings eziqinisekiswe yi-NSF/ANSI 61 yokusetshenziswa emanzini aphuzwayo, futhi ithatha lesi sitifiketi njengento yokufaka emklamo kusukela kumdwebo wokuqala hhayi njengento engezwa kamuva.
1. Lokho i-NSF/ANSI 61 Ekuqinisekisa Ngempela
I-NSF/ANSI 61 iyindinganiso yemiphumela yezempilo eyashicilelwa okokuqala ngo-1988 futhi manje isetshenziswa yizo zonke izinhlelo zokuhlinzeka ngamanzi okuphuza e-US; ihlola zonke izinto ezithinta amanzi okuphuza mayelana nezinto ezingase zikhishwe kuzo emazingeni okushisa nasezikhathini zokuthintana okulindelekile emsebenzini. Ukwakheka okudlula kuma-degree Celsius angu-20 kungase kwehluleke kuma-degree Celsius angu-40, ngakho-ke ukufakwa ohlwini kuhlotshaniswa nomsebenzi wangempela.
· Ububanzi Bemiphumela Yezempilo: Kukala izinsimbi ezikhiphekayo, izinto eziguquguqukayo kanye nezinye izinto ezingcolisayo uma kuqhathaniswa nemikhawulo yokuchayeka, hhayi ukumelana nokugqwala noma ukusebenza kwemishini.
· Ukuqinisekiswa Kwabantu Bangaphandle: Isitifiketi sikhishwa ilabhorethri egunyaziwe futhi kufanele sivuselelwe; ukuzimemezela akufani nokufakwa ohlwini.
· Izinga Lokushisa Nokugxila: Isimo esisohlwini sibalulekile. I-coating eqinisekisiwe nge-pH yamanzi okuphuza nezinga lokushisa akufanele kucatshangwe ukuthi iyasebenza emsebenzini onzima noma oshisayo.
· Ifomu Ebhaliwe: Isitifiketi sisho iresiphi eqondile yokumboza kanye nendawo ethintwayo, ngakho ukuguqulwa kwefomula kudinga ukuhlolwa kabusha.
· Ireferensi Yomthetho: Iningi lamakhodi e-U.S. ezombhobho namanzi okuphuza asho ngqo i-NSF/ANSI 61, okuyenza ibe yimfuneko engokomthetho kunokuba nje ukuthanda.
2. Lokho Okuhlanganisiwe, Nalokho Okungahlanganisiwe
Isitifiketi silandela indawo emanzi. Ethangini lengilazi elihlanganiswe nensimbi eliboshiwe lokho kusho ukumboza kwe-enamel, isivalo emhlanganisweni, noma yiziphi izinto zangaphakathi kanye namabhawudi uma ukufakwa kwawo kuthinta amanzi. Akuhlanganisi ukusebenza kwesakhiwo sensimbi, upende wangaphandle, noma ukumelana nekhemikhali okungewona amanzi okuphuza.
· Indlela Emanzi Kuphela: Yonke ingxenye ethinta amanzi agciniwe idinga isitifiketi sayo noma isimo esibhaliwe sezinga lokudla.
· Akuyona i-Corrosion Standard: I-NSF/ANSI 61 ayisho lutho ngokuthi i-coating ihlala isikhathi esingakanani noma ukuthi isebenza kanjani emanzini endle, ikhuluma kuphela ngalokho okungena emanzini okuphuzwayo.
· Akuyona i-Structural Code: I-AWWA D103-09 noma okufana nayo yendawo ilawula igobolondo; lezi zindinganiso ezimbili ziphendula imibuzo ehlukene.
· Ama-Sealant Kulula Ukuwakhohlwa: I-sealant yokuhlanganisa isendleleni yamanzi futhi kufanele ibe nesitifiketi sayo sokuphuzwa, hhayi nje i-coating.
· Ukusebenza Okushisayo noma Okunolaka: Ukuxuba, ukushisa noma amanzi afudumele ngokungajwayelekile kungashintsha iphrofayili yokufuduka futhi kungase kungabi ngaphansi kohlu.
3. Ukucacisa nokuqinisekisa isitifiketi
Umthengi kufanele acele inombolo yesitifiketi samanje, ububanzi bokwakheka okuhlanganisiwe, kanye nokuqinisekiswa kokuthi iphaneli ehlanganisiwe ne-sealant kufakwe ohlwini, bese egcina leyo ncwadi kanye nerekhodi lethangi. Ngesikhathi sokunikezela umbiko wokuhlolwa kwe-coating, irekhodi le-holiday-spark kanye nesitifiketi kufanele kuhamba ndawonye ukuze isimangalo sezempilo sikwazi ukucwaningwa eminyakeni eminingi kamuva.
· Buza ngoHlu Lwezinto: Isitifiketi sisho umkhiqizo kanye nengxenye ekhipha isitifiketi; qinisekisa ukuthi sisesikhathini futhi sihlanganisa ukwakheka okuqondile.
· Qondanisa Indawo: Qinisekisa ukuthi ukumboza okuqinisekisiwe yikona okusetshenziswe kumaphaneli alethwayo, hhayi igama lokuhweba elifanayo.
· Gcina Amarekhodi Ndawonye: Idatha yokuhlola ukumboza, imiphumela ye-holiday-spark kanye nesitifiketi kufanele kube sefayeleni elilodwa impilo yonke yethangi.
· Hlola Isivalo: Cela isitifiketi samanzi okuphuza sesivalo sokuhlanganisa ngqo, njengoba sisendleleni yamanzi.
· Qinisekisa kabusha ngoshintsho: Noma yikuphi ukwakhiwa kabusha, ukucutshungulwa kabusha noma umphakeli omusha kufanele kubangele ukuqinisekiswa ngokumelene ne-NSF/ANSI 61.

Isiqinisekiso Sobunjiniyela Nosekelo Lwephrojekthi
Wonke amathangi anikezwa yiShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) aklanywa ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobongo, uphahla kanye ne-nozzle, ahlanganiswa ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 kanye ne-ISO 45001, ahlolwa nge-holiday test ku-1500 V kuyo yonke indawo, futhi ahlanganiswa ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Amathangi okuphuza ingilazi ehlanganiswe nensimbi anikezwa nge-coating kanye ne-joint sealant eqinisekiswe ku-NSF/ANSI 61 ngomsebenzi oshiwo, isitifiketi samanje kanye nobubanzi obunikezwa namarekhodi ethangi, futhi ukwakheka kwesakhiwo kwenziwa ngokwe-AWWA D103-09 noma okulingana nako kwasendaweni ukuze kuhlanganiswe ezempilo kanye nesakhiwo.
I-NSF/ANSI 61 iphendula umbuzo owodwa kuphela: ingabe into ethinta amanzi okuphuza ingakhipha into eyingozi. Iyingxenye yencazelo evikela umthengi, futhi ihlukile kumakhodi avikela isakhiwo.
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe i-NSF/ANSI 61 iqinisekisa ithangi lonke?
Cha. Iqinisekisa izinto ezithintana namanzi okuphuza - i-coating, i-joint sealant, izinto zangaphakathi kanye namabhawodi e-plated asendleleni emanzi. Insimbi yesakhiwo, i-coating yangaphandle kanye nesisekelo zilawulwa ezinye izindinganiso. Ukuthatha isitifiketi njengokuthi sihlanganisa ithangi lonke yiphutha elivame kakhulu ekucaciseni.
Ingabe i-NSF/ANSI 61 iyadingeka ngaphandle kwe-United States?
Amazwe amaningi anezidingo zawo zokuthintana namanzi okuphuza - i-WRAS kanye ne-Drinking Water Inspectorate e-United Kingdom, i-KTW ne-DVGW e-Germany, i-ACS e-France, kanye nezinye. I-NSF/ANSI 61 yaziwa kabanzi futhi ivame ukwamukelwa, kodwa uhlu lwendawo kufanele luqinisekiswe kumphakathi womsebenzi kunokuba kucatshangwe.
Isitifiketi se-NSF/ANSI 61 sihlala isikhathi esingakanani?
Isitifiketi sigcinwa umkhiqizi futhi siqinisekiswa ngokuhlolwa kabusha ngezikhathi ezithile yinhlangano ekhipha isitifiketi; akusona isenzakalo esenzeka kanye kuphela esihlala isikhathi sokuphila kwethangi. Umthengi kufanele acele isitifiketi samanje, esingaphelelwanga isikhathi esibiza ukwakheka okuqondile okunikeziwe, futhi kufanele asigcine nemibhalo yethangi.
Ingabe ithangi lamanzi okuphuza lingenzelwa umsebenzi wethu othile?
Yebo. Umthamo kanye nokuma kwayo, izinga lokumboza kanye nobubanzi be-NSF/ANSI 61 bamanzi agciniwe, uphahla nokuphefumula, ukuhlelwa kokungena nokuphuma, ukuboniswa kwezinga, kanye nephakethe eliphelele lokuhlola nokugunyazwa kuhlelwa ngokwephrojekthi, nemibhalo yemiphumela yezempilo inikezwa ngesikhathi sokudluliswa.
