Izindinganiso Zokuklama Amathangi E-Glass-Fused-to-Steel (GFS): Umhlahlandlela Womgunyathi Wezobuchwepheshe
Kwadalwa ngo Ngokwamukisa
Izinga Lokuklama Ithangi Lengilazi Ehlanganiswe Nensimbi (GFS): Umhlahlandlela Weziphathimandla Zobuchwepheshe
Izitangi ze-Glass-Fused-to-Steel (GFS) zakhelwa futhi zenziwa ngokuhambisana namazinga amabili ayinhloko, ahambisanayo omhlaba wonke: i-ANSI/AWWA D103 kanye ne-EN ISO 28765. Ngenkathi i-AWWA D103 inikeza uhlaka lwesakhiwo lokuqinisekisa ukwakheka ngokomzimba kwesitangi, ukumelana nokuzamazama komhlaba, kanye nokubalwa komthwalo womoya, i-ISO 28765 isebenza njengesilinganiso somhlaba wonke sekhwalithi, ukumelana namakhemikhali, nokuqina ngokomzimba kwe-vitreous enamel coating. Imininingwane yokuthenga yengqalasizinda ye-GFS esebenza kakhulu kufanele ibophele ukuhambisana kokubili ukuze kuqinisekiswe impilo yesevisi yeminyaka engu-30+ ezindaweni ezinzima zezimboni noma zikamasipala.
1. Uhlaka Lwesakhiwo: AWWA D103
Izinga le-American Water Works Association (AWWA) D103 yikhodi eyinhloko yaseNyakatho Melika yamathangi ensimbi eqinile, enezicelo ezimbonini. Igxila ezingxenyeni zemishini nezakhiwo zethangi.
● Izibalo Zomthwalo: Kudingeka ukumodela okunembayo kwengcindezi ye-hydrostatic, imithwalo ye-seismic (ukuzamazama komhlaba), isivinini somoya, kanye nemithwalo yeqhwa/ophahleni.
● Imininingwane Yezinto Ezisetshenziswayo: Kubeka izidingo eziqinile zamandla okugoba ensimbi esetshenziswa emaphanelini.
● Izinto Zokuphepha: Kubeka imingcele yobuncane yokuphepha yokujiya kwe-shell, ukuhlelwa kwamabhawodi, kanye nezindawo zokuxhumana zosisekelo (njengezindonga zocingo lwe-concrete noma izisekelo eziphakanyisiwe).
● Izindlela Zokwakha: Kubusa inqubo yokuhlanganisa, okubandakanya ukusetshenziswa kwamabhawodi anamandla aphezulu, avikelwe ukugqwala, nezinqubo zokufaka ezijwayelekile.
2. Isilinganiso Sokuphelela Kwengubo: ISO 28765
Ngenkathi i-AWWA D103 iqinisekisa ukuthi ithangi ngeke libhidlike, i-ISO 28765 (I-Vitreous and porcelain enamels — Design of bolted steel tanks) iqinisekisa ukuthi ithangi ngeke ligqome. Leli yizinga elibalulekile lokuxhumana kwensimbi ehlanganiswe neglasi.
● Ukuhlukaniswa kokugqoka: Kuhlukanisa i-enamel ngezigaba zekhwalithi (AA, A, B, kanye no-C), lapho i-Class AA kanye no-A imele khona izinga eliphezulu kakhulu lokumelana namakhemikhali kanye nomzimba okudingekayo emanzini angcolile embonini kanye namanzi angcolile.
● Ukuhlolwa kokusebenza:
○ Ukumelana Namakhemikhali: Ukuhlolwa okuyimpoqo kokuchayeka kumalwelwe (isibonelo, i-sulfuric, i-citric) ukuqinisekisa ukuthi ingilazi ihlala ingasebenzi.
○ Ukushaqeka Okushisayo: Kuqinisekisa ukuthi ukugqoka kumelana nokuqhekeka phakathi nokushintsha okukhulu kwezinga lokushisa.
○ Ukushaya/Ukuklwebheka: Kulinganisa ubulukhuni bempahla (ngokuvamile u-6.0 esikalini sikaMohs) nokumelana nomonakalo ongokomzimba.
● Ukuhlolwa kwamaholide: Kudinga ukuhlolwa okungu-100% kwamaphaneli kusetshenziswa ukuhlolwa kwamandla aphezulu (ngokuvamile i-1500V) "amathuba" ukuqinisekisa ukuthi isithiyo sengilasi asinawo umoya futhi asinawo amaphutha.
3. Izitifiketi Ezihambisanayo
Kwezicelo ezikhethekile, onjiniyela kufanele babheke ngale kwezindinganiso eziyisisekelo zokuklama ukuze bahambisane nemboni ethile:
Ukuqinisekiswa | Indawo Yesicelo | Isidingo |
NSF/ANSI 61 | Amanzi okuphuza | Iqinisekisa ukuthi zonke izinto (ingilazi, izimpawu, izimpawu) azinabuthi futhi ziphephile emanzini okuphuza. |
NFPA 22 | Ukuvikelwa Komlilo | Ihlanganisa izidingo ezithile zokuklama, ukushisa, kanye nevolumu yezindawo zokugcina amanzi okucisha umlilo. |
API 12B | Ugesi & Igazi | Ngezinye izikhathi ibhekiselwa ezidingweni ezithile zokugcina eziboshiwe emkhakheni kaphethiloli. |
4. Uhlu lokuhlola lobunjiniyela lokuthenga
1. Ukuhambisana namazinga amabili: Cacisa ukufuna ukuthobela kokubili i-AWWA D103 (ezakhiwo) kanye ne-ISO 28765 (ukugqoka).
2. Isiqinisekiso sokungabi nazo izimbobo: Cacisa ukuthi "100% wamaphaneli kufanele adlule ukuhlolwa kukagesi okunamandla aphezulu (1500V) ukuze kuqinisekiswe ukuthi akukho ukungafani."
3. Ukucaciswa Kwebakala Lokugqoka: Chaza ibakala lokugqoka elidingekayo (isibonelo, "Ibakala AA noma A") ngokusekelwe ekuphazamisekeni kwamakhemikhali kwempahla egciniwe (isibonelo, pH 1–14).
4. Ukuhlolwa Kwe-TCO: Cela abafaki-sicelo ukuthi banikeze ukuhlaziywa kwezindleko zokujikeleza impilo yeminyaka engu-30, bavumele imiklamo ye-GFS eqeda isidingo sokudweba njalo ngaphakathi noma ukugqoka kabusha isakhiwo.
Cela Ukubonisana Kobuchwepheshe
Ngabe uchaza imininingwane yephrojekthi yamanzi kamasipala noma indawo yokukhipha uketshezi yezimboni? Ukuklama ngendlela engalungile kungaholela ekuhlulekeni kwangaphambi kwesikhathi kanye nokugcinwa okubizayo.
Ithimba lethu lobunjiniyela lihlinzeka nge:
● Izibalo zesakhiwo ezithile zephrojekthi (i-Seismic, Wind, kanye ne-Hydrostatic).
● Ukuhlaziywa kokuhambisana kwe-coating kumidiya ethile yamachweba, i-biogas, noma amanzi angcolile.
● Amaphakethe okuhambisa ahambisanayo ahlangabezana nezidingo ze-AWWA D103 ne-ISO 28765.
[Xhumana nethimba lethu lobunjiniyela] ukuze sixoxe ngemibandela yephrojekthi yakho, ucele isifundo sokwenzeka kwezakhiwo, noma uthole isiphakamiso esiphelele sokuhambisana.
