Amazinga Wokuklama Amathangi Ensimbi Ahlanganiswe Nengilazi (GLS): Umhlahlandlela Wegunya Lobuchwepheshe
Amathangi e-Glass-Lined Steel (GLS)—awaziwa nangokuthi i-Glass-Fused-to-Steel (GFS)—aklanywa futhi akhiqizwa ngokuhambisana namazinga amabili omhlaba ayisisekelo futhi ahambisanayo: i-ANSI/AWWA D103 kanye ne-EN ISO 28765. Ngenkathi i-AWWA D103 inikeza uhlaka lwesakhiwo lokuqina komzimba wethangi, ukumelana nokuzamazama komhlaba, kanye nezibalo zomthwalo womoya, i-ISO 28765 isebenza njengesilinganiso somhlaba wonke sekhwalithi, ukumelana namakhemikhali, nokuqina komzimba kwengqimba yengilazi evuthiwe (ingilazi). Ezinhlelweni ezihilela amanzi okuphuza, ukuhambisana okwengeziwe ne-NSF/ANSI 61 kuyimpoqo ukuze kuqinisekiswe ukuphepha kwezempilo nokuhlanzeka kwezinto.
1. Uhlaka Lwesakhiwo: Izinga le-AWWA D103
I-American Water Works Association (AWWA) D103 iyikhodi ehamba phambili yaseNyakatho Melika yamathangi ensimbi afakwe ifektri, ahlanganiswe namabhawodi. Igxile emathanjeni omklamo wethangi, iqinisekisa ukuthi isakhiwo singamelana nezingcindezi zemvelo yaso.
● Ukumodela Umthwalo: Kugcizelela izibalo ezinembile zomfutho wamanzi, imithwalo yokuzamazama komhlaba (ukuzamazama), isivinini somoya, kanye nemithwalo yophahla (iqhwa/isisindo esimile).
● Imininingwane Yezinto Zokwakha: Ibeka izidingo eziqinile zamandla okuvumela (yield strength) kanye nekhwalithi yensimbi esetshenziswa emaphaneli.
● Izixhumanisi Zesisekelo: Isungula imingcele yokuphepha yesikhala sezikulufu, ubukhulu bogobongo, kanye nobuqotho bezisekelo ezinjengezindonga eziyindilinga zikakhonkolo.
● Uhlanganiso Olujwayelekile: Ilawula inqubo yokumisa, okuhlanganisa ukuqinisa izikulufu kanye nokuvala amagasketi, ukuze kuqinisekiswe ukuthi isakhiwo asivuzi amanzi kusukela osukwini lokuqala.
2. Inkomba Yekhwalithi Yokunamathisela: ISO 28765
Ngenkathi i-AWWA D103 iqinisekisa ukuthi ithangi ngeke liwe, i-ISO 28765 (I-Vitreous and porcelain enamels — Design of bolted steel tanks) iqinisekisa ukuthi ithangi ngeke ligqwale. Lona umgomo obalulekile wokuxhumana kwengilazi nensimbi.
● Ukuhlukaniswa Kokugqoka: Kuhlukanisa uqweqwe lwawo lwe-enamel ngezigaba zekhwalithi (AA, A, B, kanye no-C), lapho i-Class AA no-A imele izinga eliphezulu kakhulu lokumelana namakhemikhali nokomzimba okudingekayo emanzini angcolile ezimbonini nasemanzini angcolile kamasipala.
● Ukuhlolwa Okuyimpoqo:
○ Ukumelana Namakhemikhali: Ukuhlolwa kokuchayeka kuma-asidi (isb., i-sulfuric, i-citric) ukuze kuqinisekiswe ukuthi ingilazi ihlala ingenamsebenzi ngokuphelele.
○ Ukushaqeka Okushisayo: Kuqinisekisa ukuthi umbo aliqhekezi phakathi nokushintshashintsha okukhulu kwezinga lokushisa.
○ Umthelela/Ukuguguleka: Kukala ubulukhuni obungaphezulu (ngokuvamile 6.0 esikalini sika-Mohs) ukuze kuqinisekiswe ukumelana nokuguguleka okuvela ezinhlayiyeni ezimisiwe.
● Ukuhlolwa Kwamaholide: Umyalo obalulekile wokuhlolwa kwefekthri okungu-100% kusetshenziswa izintambo zikagesi eziphezulu (1500V) ukuze kuqinisekiswe ukuthi isivikelo sengilazi asinazo izimbotshana futhi asinawo "amaholide" (ukungaqhubeki).
3. I-Matrix Yokuthobela: Ukukhetha Amazinga Afanele
Lapho uhlela iphrojekthi, onjiniyela kumele bacacise amazinga afanele ngokusekelwe endleleni yokugcina kanye nezimo zemvelo.
Izinga | Ububanzi Bokusetshenziswa | Ukugxila Kobunjiniyela |
AWWA D103 | Isakhiwo / Umakhenikhi | Umklamo oboshwe ngebhawodi, imithwalo yomoya/ukuzamazama komhlaba/amanzi angemi. |
ISO 28765 | Ukugqoka / Okwenziwe | Ukumelana namakhemikhali kanye nekhwalithi yensimbi ehlanganiswe nengilazi. |
NSF/ANSI 61 | Amanzi Aphuzekayo | Okungenabo ubuthi, imikhawulo yokukhishwa kwezinto eziphilayo eziphephile empilweni. |
NFPA 22 | Ukuvikelwa Komlilo | Ubukhulu, amazinga okugeleza, kanye nezidingo zamandla ombane okuvikelwa komlilo. |
4. Uhlu Lokuhlola Lobunjiniyela Lokuthenga
Uma ubhala imininingwane yephrojekthi yakho (i-RFQ), qinisekisa ukuthi lezi zindlela ezilandelayo ziyafakwa ukuze kuqinisekiswe impahla ehlangabezana namazinga omhlaba wonke:
1. Ukuqinisekiswa Kabili: Kudinga ukuthi umkhiqizi abonise ukuthobela kokubili i-AWWA D103 (isakhiwo) kanye ne-ISO 28765 (umbo).
2. Isiqinisekiso Sokungabi Namaholide: Cacisa ukuthi "amaphaneli angu-100% kumele ahlolwe ngogesi ophezulu (1500V) ukuze kuqinisekiswe ukuthi awekho amaphutha."
3. Ukucaciswa Kwezigaba Zombolo: Chaza isigaba sombolo esidingekayo (isb., "Ikilasi AA noma A") ngokuya ngobungozi bamakhemikhali ento egciniwe (isb., i-pH 1–14).
4. Ukumodela Ukuzamazama Komhlaba/Umoya: Funa umbiko we-Finite Element Analysis (FEA) oqondene nephrojekthi oqinisekisa ukuthi umklamo uhambisana nezimo zendawo yakho.
5. Ukuphepha Kwamanzi Okuphuza: Uma iphrojekthi ihilela amanzi okuphuza, gcinisa ukuthi kunesitifiketi se-NSF/ANSI 61 esivumelekile kuzo zonke izindawo zangaphakathi, kuhlanganise nezinto zokubopha nama-gasket.
