Izinzuzo Zamathangi E-Glass-Fused-to-Steel (GFS) Asetshenziswa Njengamathangi Okuhlanzwa Kwendle
Amathangi e-Glass-fused-to-steel (GFS) asetshenziswa njengamathangi okuhlanzwa kwendle ahlanganisa amandla esakhiwo sensimbi nokungasebenzi kwamakhemikhali eglasi, okunika abanikazi bezitshalo isixazululo sokugcina esingadingi ukulungiswa iminyaka engaphezu kwengu-30, esimelana namanzi angcolile anamakhemikhali ayingozi kakhulu emsebenzini womasipala.
Ukungcola kuyingozi ngokuthula: igesi ye-H2S, ama-asidi e-organic, ama-chloride namakhemikhali okuhlanza ane-alkaline asebenza ndawonye ukucekela phansi izindonga zamathangi. Ukhonkolo uyaphuka, insimbi ecwatshisiwe iyabhukuda, futhi izimali ziyachithwa. Lesi sihloko sihlukanisa izinzuzo ezine eziqinile ezenza i-GFS ibe yinto ekhethiwe yezitshalo zokuhlanzwa kwendle emazweni angaphezu kwe-100.
1. Yini Okwenza I-GFS Ibe Into Efanele Yokusebenza Kokuhlanzwa Kwendle?
Inhlanganisela engenzi lutho emibili: Ku-820–930°C, ungqimba lwe-vitreous enamel luhlangana ngamangqamuzana nensimbi. Umphumela awusona isembozo noma ulwelwesi — awukwazi ukuxebuka, ukuqhubeka noma ukuhlukaniseka, ngoba ingilazi nensimbi ziba into eyodwa.
Ukuvikelwa kwamakhemikhali okuphelele: Amakhemikhali endle ahluka kusukela kumkhiqizo we-asidi ukuya kumakhemikhali okuhlanza anobuthi. Ingaphezulu le-enamel ye-GFS limelana nokugqwala kuwo wonke ububanzi be-pH 1–14, lapho izembozo eziphilayo nokhonkolo kokubili kwehluleka khona.
Ikhwalithi eqinisekisiwe ngomthungo ngamunye: Iphaneli ngalinye le-GFS nomthungo kuhlolwa ngokuhlola kwe-1500V DC holiday (spark) ngaphambi kokuqalisa. Imiklamo ihambisana ne-AWWA D103, ISO 28765 ne-EN 1090, okunikeza onjiniyela ikhwalithi eqinisekiswa ngumuntu wesithathu.
2. Izinzuzo Ezine Zokusebenza Esitshalweni Esiphilayo Sokuhlanza Indle
Izindonga ezinganamatheli zinciphisa izindleko zokuhlanza: Ngenxa yobushubhu obungaphansi kuka-Ra 0.8 µm, udaka namafutha akwazi ukunamathela emzimbeni wethangi. Ama-clarifier namathangi okulinganisa ahlala ehlanzekile phakathi kwemijikelezo yokulungisa, kunciphisa umsebenzi wokuhlanza ezindaweni ezivaliwe.
Ukufakwa okusheshayo nokungenamthelela omkhulu: Amaphaneli aboshwe ngamabhawodi ahlanganiswa ngama-hydraulic jack ngaphandle kwama-cranes, ukushisela noma ukuqina kakhonkolo — ukufakwa kwezinsuku ezi-2–4 ngisho nangaphakathi kwezimboni ezisebenzayo, kunciphisa isikhathi sokuvala nokuthola izimvume zokuphepha.
Umthamo obheke phambili: Ngenxa yokuthi amaphaneli aboshwe ngebhawudi, indawo yokuhlanza ingangeza amaringi okuphakama noma ihambise amathangi wonke njengoba izilinganiso zokugeleza zishintsha — into engenakwenzeka ngezakhiwo ezishiselwe noma zikakhonkolo.
Izindleko eziphansi kakhulu zokuphila: Akukho ukuqopha kabusha, akukho ukuvikelwa kwe-cathodic, akukho ukulungisa ukuqhekeka. Esikhathini esingangeminyaka engu-30, izindleko zokutholakala ngokuphelele ngokuvamile ziba ngaphansi kwensimbi eqoshiwe ngo-40–60% kanye nokhonkolo ngo-20–30% uma kubalwa ukunakekela.
I-Matrix Yokuqhathanisa: I-GFS vs. Ezinye Izindlela Zokuhlanza Indle
Ipharamitha Yokuhlola | Ithangi Lokulindlela I-GFS | Insimbi Ehlanganiswe Ngokufakwa Kwendlela Yokucwiliswa | Concrete Tank |
H2S and pH 1–14 corrosion resistance | I-enamel engenamsebenzi — ihle kakhulu | Kuncike ekufakweni kwengqimba — iyahluleka eminyakeni emi-5 kuya kwengu-10 | Kulingene; ukugqwala kwensimbi nokuqhekeka |
Ukulungiswa iminyaka engu-30 | Akukho nokuncane | Ukuqopha kabusha njalo eminyakeni emi-5–8 | Ukujova ukuqhekeka, ukuvala |
Ukufakwa ezindaweni eziphilayo zezimboni | Kuboshwe ngebhawudi, kukhwishwe, akukho msebenzi wokushisa | Kudingeka izimvume zokuwelda | Ukwakha isikhathi eside kanye nokupholisa |
Ukukhulisa umthamo | Engeza amaringi aboshwe ngebhawudi | Akunakwenzeka | Akunakwenzeka |
Imibuzo Ejwayelekile (FAQ)
Umbuzo 1: Ingabe amathangi e-GFS afanele izindawo zikahulumeni zokuhlanza indle?
Yebo. Amathangi aka-GFS afakwe izinsimbi aklanyelwe ukuthi ahambisane ne-AWWA D103 kanye ne-ISO 28765 ukuze asebenze ekulinganiseni, ekungeniseni umoya, ekucaciseni nasekugcineni udaka, futhi asetshenziswa ezindaweni ezingaphezu kuka-30,000 emhlabeni wonke, kanti amanye amathangi angafinyelela ku-32,000 m³.
Umbuzo 2: Ithangi le-GFS limelana kanjani nokugqwala kwe-hydrogen sulfide?
Ungqimba lwe-glass enamel oluhlanganiswe ngezinga lokushisa eliphakathi kuka-820–930°C alunamsebenzi ngamakhemikhali futhi alunazo izimbotshana, ngakho i-H2S kanye nemikhiqizo yayo ye-sulfuric acid ayikwazi ukufinyelela kunsimbi engaphansi — lokhu kuqinisekiswa ukuhlolwa kwe-1500V DC holiday kwawo wonke amaphaneli.
Umbuzo 3: Ingabe ithangi lika-GFS lokulindlela lingafakwa ngenkathi isitshalo sisaqhubeka nokusebenza?
Yebo. Ukufakwa ngokusebenzisa i-hydraulic jacking akudingi ukushisela, akudingi ama-crane, futhi akudingi umsebenzi kakhonkolo, ngakho amathangi aka-GFS avame ukufakwa ngaphakathi kwezitshalo zokulindlela ezisebenzayo phakathi namaviki angu-2–4 ngaphandle kokuphazamiseka okukhulu.
UMBUZO 4: Ithangi lokwelapha amanzi angcolile i-GFS lihlala isikhathi esingakanani?
Amathangi e-GFS acaciswe kahle anikeza impilo yokusebenza engaphezu kweminyaka engu-30 ngaphandle kokufaka upende kabusha, uma kuqhathaniswa neminyaka engu-10–15 yensimbi eshisiwe efakwe upende kanye nokhonkolo ovuthukayo odinga ukulungiswa okuqhubekayo iminyaka engu-25–35.
