Izitsha Zensimbi Ezingezansi Zensimbi ze-AWWA D103: Isilinganiso Somhlaba Wonke Sokugcina Uketshezi
Ezinkampanini zomphakathi, izimboni zokucubungula izinto, kanye nezinethiwekhi zokuvikela imililo ezindaweni zezentengiselwano, ukugcinwa kwezinto ezingamanzi isikhathi eside kudinga ukuqina okungenamibandela kwezakhiwo kanye nokuphepha kwezempilo. Emhlabeni wonke wezobunjiniyela, i-AWWA D103 standard iyisilinganiso esicacile samathangi ensimbi akhiwe efektri. Lapho lolu hlelo oluqinile lokuklama izakhiwo luhlanganiswa nobuchwepheshe obuphezulu be-Glass-Lined Steel (obuye baziwe njenge-Glass-Fused-to-Steel noma i-GFS), umphumela uyisiqukathi esisebenza kakhulu esiklanyelwe ukuhlala amashumi eminyaka ezindaweni ezinzima kakhulu.
Njengomkhiqizi ohamba phambili wezitsha eziboshwe ngama-bolts e-Asia, i-Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) yenza ngokukhethekile ukuklama nokwakhiwa kwezitsha zensimbi ezingezansi ze-AWWA D103. Ngamalungelo obunikazi acishe abe ngu-200 kanye nomlando wokufakwa okuphumelelayo emazweni angaphezu kwe-100, i-Center Enamel ihlinzeka ngengqalasizinda yesimanje yokugcina ehlangabezana nekhodi eziqinile zamazwe omhlaba zobunjiniyela nezemvelo.
1. Ukuqonda Isilinganiso se-AWWA D103-09
I-American Water Works Association (AWWA) yasungula i-AWWA D103-09 standard ukuze ilawule ukuklama, ukwakha, kanye nezincazelo eziqondile zezinto zokwakha ezisetshenziselwa amathangi ensiza amanzi anokwakhiwa kwefektri.
Ukuhambisana ne-AWWA D103 kuqinisekisa ukuthi ithangi lokugcina alisona nje isiqukathi, kodwa iyinsiza yokwakha eklanywe kahle. Le standard ibeka imithetho eqinile yokuthi:
● Ukuklama kweSeismic: Ukubala i-base shear ethile, imizuzu yokuphenduka, kanye nokusheshisa kwendawo ukuze kuvinjelwe ukugoba kwesakhiwo ngesikhathi seziqubu.
● Ukulayisha Komoya Nefu: Ukuhlela umoya onamandla (kuze kube phezulu nangaphezulu kwamandla e-hurricane) kanye nezinsiza ezinzima ezibangelwa ukuhlanganiswa kwefu okukhona.
● Ubukhulu Obuthile Nezinsiza zeHydrostatic: Ukulungisa ukuqiniswa kwesakhiwo ngokusekelwe ebunzimeni bamanzi agcinwe—noma ngabe amanzi ahlanzekile okuphuzwa kwasemadolobheni noma i-sludge yezimboni enobukhulu obuphezulu.
I-Hydrostatic Engineering Formula
Ukuze kuqinisekiswe ukuthobela ngokuqinile imingcele yokuphepha ye-AWWA D103-09, abunjiniyela be-Center Enamel balinganisa ubukhulu obuqondile besikhumba esidingekayo sengxenye ngayinye evundlile yethange eliboshiwe.
Ngokusebenzisa ukuhlaziywa kwe-finite element (FEA) kanye nalezi zindinganiso, i-Center Enamel ilinganisa ubukhulu obuqondile bamaphaneli ensimbi ashisayo, isebenzisa amapuleti amakhulu esisekelweni lapho ingcindezi ye-hydrostatic iphakeme kakhulu, futhi ilungisa izindandatho ezingaphezulu ukuze kube lula isisindo nokusebenza kahle kwezimali.
2. Inzuzo Yobuchwepheshe Be-Glass-Lined (GFS)
I-AWWA D103 ichaza izidingo zensimbi yesakhiwo, kodwa impilo yokusebenza yethangi incike kakhulu ku-coating yayo yangaphakathi nangaphandle. I-Center Enamel ingumkhiqizi wokuqala e-China ukuthuthukisa ngokuzimela ubuchwepheshe be-enameling ohlangothini olubili kumapuleti ensimbi ashunyiwe ashisayo, kudala ubuso be-Glass-Lined Steel obungenakuqhathaniswa.
● Ukuhlanganiswa Kwezinga Lokushisa Eliphezulu: Impuphu ye-glass enamel ihlanganiswa unomphela nesisekelo sensimbi kuhhavini wezinga lokushisa eliphezulu ku-800°C. Lokhu kudala ukubopha okuyingqayizivele kwe-physicochemical phakathi kwengilazi nensimbi.
● Ukuqina Kwamakhemikhali Nokuqina: Ingaphezulu lengilazi eligqitshwe ensimbi libala u-7 esikalini sokuqina se-Mohs. Linikeza ukungangeni ngokuphelele ezindaweni zezimboni ezinama-acid kakhulu (i-pH 2.0) ne-alkaline (i-pH 11.0), okwenza kube ngcono kakhulu kunezendlalelo ze-epoxy ezijwayelekile noma insimbi yekhabhoni eyenziwe ngemishini yasensimini.
● Ukuphepha Kwesithuthukisi: Ingaphakathi lengilazi eligudile, elingenawo umoya livimbela ukwakheka kwe-bio-film nokubuthana kwamagciwane. Amathangi e-GFS e-Center Enamel anesitifiketi se-NSF/ANSI 61 kanye ne-WRAS, aqinisekisa ukuthi akukho ukudonswa kwamakhemikhali emithonjeni yamanzi okuphuza yomphakathi.
3. Ukuhambisana Nekhwalithi Yomhlaba Wonke kanye Nokwenziwa Ngaphambi Kokwakhiwa
I-Center Enamel yenza konke ukukhiqiza ngaphakathi kwesisekelo sayo sokukhiqiza esithuthukisiwe esingu-150,000m². Le ndlela yokukhiqiza eyenziwe yaba yisikhungo esisodwa, eyenziwe ngokuvundlile isusa ukungafani kokwakhiwa kwensimu:
● Akukho Msebenzi Womlilo: Ngoba amaphaneli enziwe embonini futhi ashonelwe izimbobo, ahlanganiswa endaweni ngokusebenzisa izikulufo ezakhiwe ngamandla kanye nezinto zokubopha ezingeni eliphezulu. Lokhu kuqeda ukushisela ngomlilo ovulekile ensimini, okonga isikhathi esiningi futhi kunciphisa ingozi yokugqwala okubangelwa ukushisa endaweni ethile.
● Ukuhlolwa kwe-ISO 28765: Wonke iphaneli elilodwa le-Glass-Lined lihlolwa kakhulu nge-1500V high-voltage holiday testing ukuqinisekisa ukuthi alinawo amaphutha (pinhole-free) ngaphambi kokuba lishiye ifektri.

4. Ukukala Okungafani Nokusebenza Kwezimboni Eziningi
Amathangi Ensiniyela ye-Center Enamel enza ngokwe-AWWA D103, asetshenziswa emhlabeni wonke emikhakheni ehlukahlukene, efakazela ukumelana kwawo ezindaweni ezishisayo ezisuka ezigwadule zaseMiddle East kuye ezindaweni zaseCanada ezingaphansi kwezinga lokubanda.
Ngamandla okuklama ivolumu enkulu kunazo zonke ye-GFS tank eyodwa kufika ku-32,000m³, lezi ziqukathi ezihlangene zilungele:
● Ingqalasizinda Yomasipala: Ukugcinwa kwamanzi okuphuza anomthamo omkhulu, amathangi okucacisa, namachibi okulinganisa imisele.
● Ukwelashwa Kwamanzi Angcolile Embonini: Ukugcinwa okuqinile kwamanzi anobuthi njengamanzi angcolile embonini yemithi, ubisi, kanye nemboni kawoyela wezintende (POME).
● Bio-Energy Ebuyisela Amandla: Amathangi e-Anaerobic Digestion (AD) aqine kakhulu, ama-CSTR, nama-UASB reactors angahlupheki yi-hydrogen sulfide (H2S) ekhishwa ngaphakathi.
Ubunjiniyela Obuthembekile Bezinsiza Zomhlaba Wonke
Ukutshala imali ethangini le-Glass-Lined Steel elihambisana ne-AWWA D103 kuqinisekisa impahla yengqalasizinda eyakhelwe ukusebenza okunamandla kwezakhiwo nokumelana namakhemikhali okungcono kakhulu. Ngokuhlanganisa leli zinga eliqinile lobunjiniyela baseMelika nobuchwepheshe obuthuthukisiwe be-double-sided enameling, i-Center Enamel ihlinzeka abasizi bomhlaba wonke kanye nabasizi bezimboni ngezixazululo zokugcina ezisebenza kahle, ezakhiwe ngamamojula eziklanyelwe impilo engu-30+ yeminyaka ngaphandle kokugcinwa.
Qinisekisa ukuthobela ngokuphelele imithetho futhi uvikele izimpahla zakho ezingamanzi ngethange eliqinile eliboshiwe emakethe. Thinta i-Center Enamel namuhla ukuze uxoxisane nethimba lethu lobunjiniyela ngomklamo we-AWWA D103 owenziwe ngokwezifiso iphrojekthi yakho elandelayo yomhlaba wonke.
