Ithangi Lokugcina Amanzi Omlilo: Umhlahlandlela Ophelele Wolwazi
Ithangi lokugcina amanzi okuqeda umlilo liwukuhlangana okuchaziwe kwegobolondo, isisekelo, izixhumanisi, izilawuli zamazinga, ukushisisa, kanye nezinhlelo zokuchichima, okwakhiwe ngokumelene nemephu yezindinganiso ezimilelayo — i-NFPA 22 yethangi, i-NFPA 20 yepompo, i-NFPA 13 noma i-EN 12845 yokusabalalisa, kanye ne-FM noma i-AWWA lapho ukugunyazwa noma ukuthengwa kudinga lokho.
Le ncwadi yokuhola ibhalwe njengendawo eyodwa yokubhekisela kwithangi lokugcina amanzi okuqeda umlilo: ukuthi lenziwe ngaluphi uhlobo lwempahla, yiziphi izingxenye okufanele zibe khona, ukuthi lezo zingxenye zisebenza kanjani, nokuthi yiziphi izindinganiso ezilawula ingxenye ngayinye. Ngokungafani ne-athikili eqondene nokusetshenziswa okuthile, inhloso lapha iwukuba yisichazamazwi — ukunikeza abacacisi, ama-EPC, nonjiniyela bezimboni umbono ohlanganisiwe wethangi njengempahla ephelele. Ulwazi olungezansi lwakhiwe ngokuzungeza izindinganiso eziqanjiwe kanye nemingcele eqinisekisekayo kuphela; alucaphuni ukufakwa okuthile kwephrojekthi njengesihloko salencwadi yokuhola.
Ithangi Lokugcina Amanzi Okuqeda Umlilo Lichazwa Ngokuthi Indwangu Yegobolondo Nohlelo Lokumboza
Ukuhlukaniswa okuyisisekelo kakhulu kwethangi lokugcina amanzi omlilo umateriali kanye nohlelo lokuvikela lwegobolondo lalo, ngoba lokho kunquma ukuziphatha kwesikhathi sokuphila phakathi nezikhathi ezinde zokungenzi lutho. Amathangi ensimbi ashiselwe ancike kuma-coating afakwa endaweni noma afakwa esitolo; amathangi kakhonkolo ayizakhiwo ezinkulu ezinamalayini angaphakathi; kanti amathangi ensimbi acwebezelisiwe agxunyekwe ngezinto ezincibilikisiwe (GFS) asebenzisa i-enamel encibilikiswe efektri enamathela ensimbini ku-820–930 °C. Indlela ngayinye inemiphumela ehlukene ekumelaneni nokugqwala, ububanzi bokushisela endaweni, kanye nezindlela zokugunyazwa. Ithebula elingezansi lifingqa izinketho ezijwayelekile zegobolondo njengereferensi.

Imephu Yamazinga Ibeka I-NFPA 22 Phakathi Nokuklanywa Kwethangi
Imigomo elawula ithangi lokugcina amanzi okuqeda umlilo ihlukene ngezigaba. I-NFPA 22 iyincwadi eyinhloko yethangi ngokwalo — ukwakhiwa kwalo, indawo elikuyo, kanye nenani lamanzi adingekayo kanye nengcindezi. I-NFPA 20 ilawula iphampu yomlilo edonsa kuleli thangi. I-NFPA 13 (kanye ne-EN 12845 yamaphrojekthi aseYurophu) ilawula ukusatshalaliswa kwezifutho zokucisha umlilo okusetshenziswa ithangi ekugcineni. I-FM Global DS 1021 kanye ne-AWWA D103-09 zingena lapho imvume yomshuwalense wempahla noma incazelo yokuthenga idinga indinganiso eyamukelekile. Ukuqonda ukuthi iyiphi indinganiso ephethe umsebenzi othile kuvimbela iphutha elivamile lokucacisa ngokweqile noma ngaphansi kwethangi.
Isahluko 14 Se-NFPA 22 Sikhuluma Ngokuvikelwa Kwe-Coating Nokugqwala Kwethangi
Ukukhethwa kwekhodi yokumboza kucaciswa ngokusobala ngaphakathi kwe-NFPA 22, kuhlanganise neSahluko 14 esihlanganisa izinto zokumboza zokuvikela zangaphakathi nangaphandle kwethangi. Emathangini ensimbi ahlanganiswe ngengilazi aboshwe ngezibholo, uhlelo lwe-enamel lunikeza enye indlela elawulwa efektri esikhundleni sezinto zokumboza ezisetshenziswa endaweni, nemingcele efana nogqinsi lwe-enamel olungu-0.25–0.45 mm, ukuqhubeka kwendawo Ra < 0.8 µm, ukunamathela okungaphezu kuka-3,450 N/cm², kanye nokuhlolwa kwenhlansi ye-1,500 V DC okuqinisekisa ukuqhubeka. Le mingcele elinganisekayo inikeza umcacisi isisekelo esingachemi sokwamukela esizimele ekuhlolweni kwezinto zokumboza okungokomzwelo.
Ukulawulwa Kwezinga, Ukushisisa, Nokuchichima Kuyimisebenzi Yokuphepha Ehlangene
Uhlelo lwamazinga kanye nokuchichima kuyizingxenye ezimbili zenkinga yokulawula efanayo: ithangi kufanele lihlale liphethe indawo yawo yokugcina yomlilo edingekayo, kodwa akumele neze lichichime. I-valve yokugcwalisa iphinda igcwalise ifinyelela endaweni ebekiwe yezinga eliphezulu; isexwayiso sezinga eliphansi sixwayisa ngaphambi kokuba indawo yokugcina yonakaliswe; ukuchichima kuthwala okweqile ngaphandle kokulimaza izinga. Ukushisa — i-electric trace, indawo evalekile, noma ukugcwalisa okushisayo — kugcina uketshezi olugciniwe ezindaweni ezibandayo. Akukho kulokhu okusebenzayo okuyisihloko sokuzikhethela ekufakweni okuhambisana nemithetho, futhi kufanele kucaciswe ndawonye.
Izindlela Zokuqinisekisa Zincike Emakethe Yephrojekthi Nekhomanisi Lokugunyaza
Isitifiketi okufanele sithwalwe yithangi lokugcina amanzi omlilo siqhutshwa yimakethe. I-NSF/ANSI 61 ne-WRAS ziyasebenza lapho indawo ethintana namanzi ilawulwa khona; ukumakwa kwe-CE ngaphansi kwe-EN 1090 kuyasebenza emakethe yaseYurophu; i-ISO 28765 iyasebenza ekwakhiweni kwamathangi aboziwe nge-enamel; imvume ye-FM ivame ukudingeka ngabashicileli bezimpahla. Ithangi elingafakazelwa ngaphansi kwezindlela eziningi linciphisa ingozi yokuthenga kumaphrojekthi okuthekelisa, yingakho abakhiqizi begcina isitifiketi esihambisanayo esikhundleni semvume eyodwa yesifunda.
