Indlela Yokuhlola Umkhiqizi Nomhlinzeki Wethangi Lamanzi Omlilo
Ukuhlola umkhiqizi wethangi lamanzi okuqeda umlilo kusho ukuqinisekisa isitifiketi ngokuhambisana nomgudu wekhodi yomlilo ngaphambi kokuxoxa ngentengo: ubufakazi bokumboza nokufakwa kolwelwesi (AWWA C550, ISO 28765), uhlelo lwekhwalithi yokushisela nokwakha olubhalisiwe (ISO 9001, ISO 45001), ubufakazi bomthamo owethulwe ngempela esikhundleni sosayizi wamapuleti okungelona iqiniso, ukulethwa phesheya okubonisiwe, kanye nezinkomba ezihambisana nezinga elihlosiwe (NFPA 22 noma EN 12845). Umhlinzeki ongakwazi ukukhombisa lezi zinto uyingozi esigcinweni somlilo esibalulekile, ngoba ithangi kufanele lidlule ekubuyekezweni kwe-AHJ noma kwabanye abangaphandle futhi lihlale lisebenza amashumi eminyaka. Ukucwaninga kuwuhlu lokuhlola, hhayi ukuxoxisana, futhi kufanele kuqedwe ngaphambi kokuba isilinganiso semali samukelwe.
Ithangi lokugcina amanzi okuqeda umlilo akusilo idramu lezimpahla; liyisitsha esilawulwa yikhodi okufanele sidlule ekubuyekezweni yiziphathimandla bese sihlala sigcwele futhi singenzi lutho iminyaka ngaphambi kokuba sidingeke. Ukukhetha umhlinzeki wethangi lamanzi okuqeda umlilo ongafanele kubiza kakhulu ngendlela embi kakhulu — ukwehluleka kuvela ngesikhathi sokuvulwa noma, okubi kakhulu, emlilweni. Ngakho-ke abathengi badinga ukuhlolwa okuhlelekile okuhlukanisa abahlinzeki abangafakazela ukuthobela imithetho kulabo abavele bathi bayayithobela. Le ndatshana ibeka uhlu lokuhlola esilusebenzisa lapho siqinisekisa umkhiqizi wethangi lamanzi okuqeda umlilo, kusukela kuzitifiketi ezivimbela konke okunye kuye kwezokuhweba ezinquma ukuthi ithangi liyafika ngempela yini.
Izitifiketi Zivimbela Ukuhlolwa Konke
Umkhiqizi wethangi lamanzi othembekile womlilo uhola ngokugunyazwa kwekhodi yokumboza nokufaka ulwelwesi, ngoba yilokho okubhekwa kuqala yikhodi yomlilo kanye ne-AHJ. Ukuvikelwa kwangaphakathi kwethangi lomlilo kuyisici saso esiyisisekelo sokuphepha ngezikhathi ezinde zokungenzi lutho, ngakho-ke imibhalo kufanele isho izinga, hhayi nje into esetshenzisiwe.
· I-AWWA C550 ihlanganisa izinto zokumboza zangaphakathi nangaphandle zokulawula ukugqwala kwamathangi amanzi ensimbi futhi iyisithenjwa esilindelwe amaphrojekthi amaningi omlilo aseNyakatho Melika.
· I-ISO 28765 iyindinganiso yokuklama yamathangi ambozwe nge-vitreous enamel (GFS), ecacisa uhlelo lwe-enamel, ukunamathela nokuhlolwa okwenza ithangi lomlilo le-GFS lihlolwe futhi limelane nokumiswa.
· I-NSF/ANSI 61 iqinisekisa ukuthi ulwelwesi lwamukelekile ekuxhumaneni namanzi okuphuza lapho isigcino singaxhunyaniswa khona namanzi okugcwalisa.
Umhlinzeki ocaphuna "i-epoxy lining" noma "i-enamel" ngaphandle kokusho izinga nokunikeza isitifiketi kufanele abekwe eceleni kungakhathaliseki intengo.
