Ikuphi ukumboza okuphephile ekuthintaneni namanzi okuphuza?
Igama elithi kuphephile lenza umsebenzi wangempela lapha. Ukumboza kungamelana nokugqwala ngokuphelele futhi kusavumela izingcosana ze-monomer, i-plasticiser noma insimbi esindayo ukuthi ingene emanzini ahlala kukho izinsuku eziningi. Okwenza i-lining iphephele emanzini okuphuza isitifiketi semiphumela yezempilo ngokwesimo sangempela sokuthintana, hhayi incazelo yomhlinzeki ethi 'izinga lokudla' noma 'akunabo ubuthi'. Isitifiketi, hhayi isiphawulo, ubufakazi.
I-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) ihlinzeka ngamathangi e-glass-fused-to-steel anendawo ye-vitreous enamel eqinisekiswe yi-NSF/ANSI 61 ukuze ithinte namanzi okuphuza, futhi yeluleka ukuthi kukhethwe i-lining ngokwesilinganiso sesitifiketi hhayi ngegama lezinto kuphela.
1. Izinto Zokumboza Ezidlula Ukuhlolwa Kwamanzi Okuphuza
Imindeni eminingana yezinto zokufaka ezingaphakathi ingahlangabezana nezinga lokuxhumana namanzi okuphuza uma yenziwe ngalokho: i-vitreous enamel ehlanganiswe nensimbi, i-fusion-bonded epoxy, i-polyurethane ethile engenawo ama-solvent kanye nodaka lwe-cementitious. Iphuzu elibalulekile ukuthi ukwakheka okuqondile kuhlolwe ezingeni lokushisa lokusebenza kanye ne-pH, hhayi ukuthi isigaba sezinto sithathwa njengesingenzi ngokujwayelekile. I-epoxy ejwayelekile ayiphephile ngokuzenzakalelayo; iresiphi ebaliwe yiyo ephephile.
· I-Vitreous Enamel: Ihlanganiswe ku-820-930 degrees Celsius ibe ungqimba lwengilazi, ayinazinto eziyizingozi futhi, uma ibaliwe, ayikhiphi lutho emanzini.
· I-Fusion-Bonded Epoxy: I-coating yempushana ye-thermoset engabhalwa ku-NSF/ANSI 61 yomsebenzi wokuphuza uma yenziwe futhi yavuthwa ngendlela efanele.
· Izinto Zokufaka Ze-Cementitious: Zisetshenziswa kwamanye amathangi ensimbi kanye nekhonkrithi, kodwa kufanele zihlolwe ngokwazo mayelana nezinto ezingakhipha.
· Upende Ongabaliwe: Upende we-alkyd noma we-latex ogcotshwa endaweni akuvamisile ukuqinisekiswa ukuthi angasetshenziswa ekuxhumaneni namanzi okuphuza futhi akufanele kucatshangwe ukuthi aphephile.
· Okufakiwe Ohlwini, Akubhalwanga: Funa inombolo yesitifiketi kanye nobubanzi; ilebula elithi 'izinga lokuphuza' ngaphandle kokufakwa ohlwini akulona ubufakazi.
2. Okushiwo yi-Inert Empilweni Yangempela
Ulayini we-inert awusabeli emanzini, awuncibiliki kuwo, futhi awusekeli ukukhula kwezinto eziphilayo ebusweni bawo. I-Enamel ikufinyelela lokhu ngokuba ungqimba lwengilazi elihlangene olungenasibopho sezinto eziphilayo esingabola. Lokho kubalulekile ngoba ulayini owonakala kancane ushintsha izinga lamanzi phakathi neminyaka engama-30 yokuphila kwethangi, okuyisikhathi esiqondile isivivinyo semiphumela yezempilo esihloselwe ukusibhekana naso.
· Akunasibopho sezinto eziphilayo: I-Enamel ehlangene ayinayo i-resin yokuhlanza noma yokukhipha, ngokungafani nezinye izinto zokumboza ezisetshenziswayo.
· Okubushelelezi Futhi Okuhlanzekayo: Indawo eqinile ecishe ibe ngu-6.0 Mohs imelana nokunamathela kwe-biofilm futhi kulula ukuyigeza.
· Kuzinzile Emashumini Eminyaka: Ukungasebenzi kufanele kuqhubeke isikhathi sokuphila kwethangi, hhayi nje ngesikhathi sokuqala.
· Akunambitheki Noma Iphunga: Isembozo esiqinisekisiwe asinikeli lutho olubonakalayo emanzini.
· Kuqinisekisiwe, Akushiwo Nje: Ukungasebenzi kufakazelwa ukuhlolwa kokufuduka, hhayi ukusho kokumaketha.
3. Ukucacisa Isembozo Esiphephile
Incazelo kufanele ibize izinga (NSF/ANSI 61 noma okulingana nako endaweni), idinge isitifiketi sokuqoka esiqondile nesivalo, futhi iveze izinga lokushisa lokusebenza ne-pH. Kufanele futhi idinge irekhodi lokuhlolwa kokuqoka nemiphumela ye-holiday-spark ngesikhathi sokunikezwa. Ekwakhiweni okuboshiwe isivalo sokuhlangana sisendleleni yamanzi futhi sidinga isitifiketi saso, okuyinto evame ukunganakwa.
· Qamba i-Standard: Bhala ngokusobala i-NSF/ANSI 61 noma izinga likazwelonke elisebenzayo lokuthintana namanzi okuphuza.
· Qinisekisa Ikhodi Nokugcotshwa: Kokubili umugqa wangaphakathi kanye nenhlanganisela yamalunga kuthinta amanzi futhi kufanele kufakwe ohlwini.
· Shono Umsebenzi: Bhala izinga lokushisa lokusebenza, ububanzi be-pH kanye nanoma yisiphi isibulala-magciwane esikhona.
· Dinga Amarekhodi Okuhlolwa: Ukujiya kokugcotshwa, i-holiday-spark kanye nedatha yokunamathela kufanele kuhambisane nesitifiketi.
· Phikelela Ekulandeleleni: Izinombolo zamaphaneli kufanele zixhumeke emuva eqenjini eliqinisekisiwe kanye nombiko wokuhlolwa.

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 wegobolondo, uphahla kanye ne-nozzle, ahlanganiswa ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, ahlolwa nge-holiday test ku-1500 V kulo lonke ubuso, futhi ahlanganiswa ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Amathangi e-glass-fused-to-steel okusetshenziselwa amanzi okuphuza anikezwa nge-enamel kanye ne-joint sealant eqinisekiswe yi-NSF/ANSI 61 yomsebenzi oshiwo, isitifiketi kanye namarekhodi okuhlola anikezwa ngesikhathi sokudluliselwa, futhi umklamo wesakhiwo wenziwa ngokwe-AWWA D103-09 noma okulingana nayo yendawo.
Isembozo esiphephile sokudla esisetshenziswayo yileso esinesitifiketi semiphumela yezempilo yefomula nemsebenzi oqondile - hhayi leso esichazwa njengezinga lokudla. Ukungangenisi, ukuhlanzeka kanye nendawo ezinzile yeminyaka engama-30 yikho isitifiketi esikuvikelayo ngempela.
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe insimbi engagqwali iphephile ngaphandle kwesembozo?
Insimbi engagqwali engu-304 noma engu-316L yamukelwa kabanzi emanzini aphuzwayo futhi ngokuvamile ayidingi isembozo, kodwa kusamele ikhethwe ngokwamakhemikhali amanzi - amanzi afudumele ane-chlorine angabangela ukugqwala ezingeni eliphansi. Ngisho nezingxenye zangaphakathi zensimbi engagqwali, imithungo kanye namagaskethi kufanele kuqinisekiswe ukuthi ziyafaneleka ukuthintana nokudla esikhundleni sokucatshangelwa nje.
Ingabe ithangi elikhona lingenziwa liphuzwe ngokuphinda lipendwe?
Kwesinye isikhathi, kodwa kuphela nge-lining ephethe isitifiketi samanje sokuxhumana namanzi aphuzwayo ngenhlanganisela eqondile futhi efakwa endaweni elungiselelwe kahle. Izinto zokumboza ezindala nokungcola kufanele kususwe kuqala, futhi i-joint sealant nayo idinga isitifiketi. Ukupenda nje ngaphakathi akwenzi ithangi libe eliphuzwayo.
Ingabe ukujiya okuphezulu kwe-coating kusho amanzi aphephile?
Cha. Ukujiya kuthinta ukuqina nokumboza, hhayi ukukhipha izinto eziyingozi. I-lining encane eqinisekisiwe iphephile kune-lining enkulu engaqinisekisiwe. Umbuzo wezempilo uphendulwa ukuhlolwa kokufuduka, kanti umbuzo wokuqina uphendulwa ukujiya, ukunamathela nobulukhuni ndawonye.
Ingabe ithangi lamanzi aphuzwayo lingenzelwa ikhemistri yethu yamanzi?
Yebo. Izinga lokufaka kanye nobubanzi besitifiketi, izinga lokushisa lokusebenza kanye ne-pH envelope, uphahla kanye nokukhipha umoya, ukuhlelwa kokungena nokuphuma kanye nephakethe eliphelele lokuhlola nesitifiketi kuhlelwe ngokwamanzi, futhi imibhalo inikezwa ngesikhathi sokudluliselwa.
