Isiphi isitifiketi esisebenza ekugcotshweni kwesilo sokusanhlamvu?
Okusanhlamvu kuwukudla okomile, futhi udonga lwesilo okuhlezi kulo luyindawo ethinta ukudla izinyanga ngezinyanga. Ngakho-ke i-coating idinga isitifiketi sokuthinta ukudla, kodwa esifanele umthetho wokudla okomile hhayi umthetho wamanzi okuphuza. Isitifiketi sokufaneleka ukuphuzwa siyisibonakaliso esizwakalayo sokungangenisi kalula, kodwa asigcwalisi ngokwaso umthetho wokuthinta ukudla okungaphansi kwawo ukugcinwa kokusanhlamvu, yingakho incazelo kufanele ibize izinga elifanele.
I-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) ihlinzeka ngamasilo okusanhlamvu ane-enamel ne-sealant ekhethelwe ukuhambisana nokuthinta ukudla, futhi yeluleka ukuthi isitifiketi se-coating sihlangane nemakethe okuzothengiswa kuyo ukusanhlamvu esikhundleni sokuthembela esimweni esijwayelekile.
1. Ukuthinta Ukudla, Hhayi Ukuphuzwa, Ukuvivinyo
Okusanhlamvu okugciniwe kulawulwa njengokudla, ngakho-ke ukumbozwa kodonga kufanele kuhlangabezane nomthetho wezinto ezithinta ukudla - e-United States lokho yi-FDA's Food Contact Substance framework ngaphansi kwe-21 CFR, e-European Union yi-Framework Regulation (EC) 1935/2004 kanti ama-plastiki alawulwa yi-10/2011, kanti e-Germany yi-LFGB. Le mithetho ikhawulela lokho okungasuka ekubozweni kungene ekudleni. Isitifiketi samanzi okuphuza siphendula umbuzo ohlukile futhi akufanele kucatshangwe ukuthi siyazanelisa.
· U.S. - FDA 21 CFR: Izinto ezithinta ukudla zigunyazwa futhi kubekwa imikhawulo yokungena ekudleni.
· EU - 1935/2004: Izinto akufanele zidlulisele izakhi ezisongela impilo noma ezishintsha ukudla.
· EU - 10/2011: Ilawula izingqimba zepulasitiki futhi ibeka imikhawulo yokungena iyonke.
· Germany - LFGB: Ikhodi kazwelonke yokudla nokuphakelayo esetshenziswa ezintweni ezithintwayo.
· Umehluko Wokudla Okomile: Okusanhlamvu kumile, ngakho-ke ukungena kuncane kunoketshezi, kodwa umthetho usasebenza.
2. Kokubili I-Coating kanye Nomhlangano Kubalulekile
Esilweni esiboshiwe, udonga lwe-enamel kanye ne-sealant yomhlangano kokubili kuthinta okusanhlamvu. Udonga oluqinisekisiwe olune-sealant engaqinisekisiwe lushiya igebe, ngoba i-sealant ingangena okusanhlamvu emgqeni womhlangano. Incazelo kufanele ifune isimo sokuthintana nokudla kukho kokubili, kanye nanoma yikuphi ukufakwa kwangaphakathi okuthinta okusanhlamvu.
· Udonga Lwe-Enamel: I-vitreous enamel iyingilazi engasebenzi futhi ifaneleka kahle ekuthintaneni nokudla okomile uma kufakwe ohlwini.
· I-Sealant Emhlanganweni: I-sealant yomhlangano eboshiwe nayo ithinta okusanhlamvu futhi idinga isimo sezinga lokudla.
· Izinto Zangaphakathi: Izinzwa zamazinga, ama-auger namahopha athinta okusanhlamvu kufanele futhi kuhambisane.
· Isixhumanisi Esisodwa Esibuthakathaka: Isivalo esingaqinisekisiwe singonakalisa isilo esihambisana nomthetho.
· Kubhale Phansi: Gcina isitatimende sokuthintana nokudla namarekhodi ethangi.
3. Ukucacisa Imakethe
Isitifiketi esifanele sincike ekutheni okusanhlamvu kudliwa kuphi. Okusanhlamvu okuthunyelwa e-EU kudinga i-EU 1935/2004 futhi, lapho kukhona amapulasitiki, ukuhambisana ne-10/2011; okusanhlamvu kwemakethe yase-US kudinga isimo sokuthintana nokudla se-FDA; okusanhlamvu kwaseJalimane kuzuza ku-LFGB. Ukusho imakethe eqondiwe encazelweni kususa ukungaqondakali futhi kuvimbele ukugcotshwa kabusha okubizayo noma ukwenqatshwa ekungenisweni.
· Shono Imakethe: Shono indawo ekuyiwa kuyo ukuze kusetshenziswe umthetho ofanele.
· Cela Isitatimende: Cela idokhumenti yokuhambisana nokudla, hhayi ilebula kuphela.
· Qhathanisa Ukwakheka: Qinisekisa ukuthi iresiphi eqinisekisiwe yiyo enikezwayo.
· Gcina Ivuselelwa: Izitatimende zokuhambisana kufanele zibe zesikhathi samanje ekulethweni.
· Hlola I-Sealant: Inhlanganisela yokuhlanganisa idinga isimo sayo sokudla.

Isiqinisekiso Sobunjiniyela kanye Nosekelo Lwephrojekthi
Wonke amathangi anikezwa yiShijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) aklanywa ngokuhambisana ne-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomthwalo wegobongo, uphahla kanye ne-nozzle, ahlanganiswe ku-820-930°C ngaphansi kokulawulwa kwe-ISO 9001 ne-ISO 45001, ahlolwe nge-holiday test ku-1500 V kuyo yonke indawo, futhi ahlanganiswe ngamabhawodi e-Grade 8.8 kanye ne-sealant eqinisekiswe umkhiqizi. Ama-silo okugcina okusanhlamvu anikezwa nge-enamel kanye ne-joint sealant ekhethelwe ukuhambisana nokudla emakethe okuhlosiwe, isitatimende noma isitifiketi esifanele sinikezwa namarekhodi ethangi, futhi umklamo wesakhiwo wenziwa ngokomthwalo wokusanhlamvu okugciniwe kanye nokungenisa umoya nokuphefumula okudingwa isitshalo.
Okusanhlamvu kuwukudla, ngakho-ke i-coating ye-silo idinga isitifiketi sokuthintana nokudla - i-FDA 21 CFR e-U.S., i-EU 1935/2004 (kanye ne-10/2011 yamapulasitiki) eYurophu, i-LFGB eJalimane - hhayi isitifiketi samanzi aphuzwayo. Udonga kanye ne-joint sealant kufanele kokubili kuhambisane.
Imibuzo Evame Ukubuzwa (FAQ)
Ingabe isitifiketi se-NSF/ANSI 61 sanele kwi-silo yokusanhlamvu?
Kuyisikhombisi esiwusizo sokuncipha kokukhipha kodwa akusona isimiso sokusanhlamvu. Okusanhlamvu kulawulwa njengokudla ngaphansi kwe-FDA 21 CFR, EU 1935/2004 noma LFGB, okubeka imikhawulo yokufuduka kokudla okuthintwayo. I-silo ebheke kulezi zimakethe kufanele ibe nesitatimende esifanele sokuthintana nokudla esikhundleni sokuthembela esitifiketini samanzi okuphuza.
Ingabe i-enamel idinga izinga lokudla uma okusanhlamvu kukomile?
Yebo. Okusanhlamvu okomile kusasekwe odongeni izinyanga eziningi, futhi umthetho wokuthinta ukudla uyasebenza kungakhathalekile umswakama. Inzuzo ukuthi ukufuduka kusuka ku-vitreous enamel engasebenzi kuye okusanhlamvu okomile kuncane, kodwa ukuhambisana kusafanele kubhalwe phansi kunokucatshangwa.
Kuthiwani nge-silo ye-galvanized yokusanhlamvu?
Insimbi ye-hot-dip galvanized isetshenziswa kabanzi okusanhlamvu futhi ngokuvamile yamukelwa ekuthinteni ukudla okomile, kodwa ungqimba lwe-zinc nanoma yikuphi ukumboza noma i-passivation kufanele kuqinisekiswe emakethe okuhlosiwe. Okusanhlamvu kwesikhathi eside noma kwenani eliphezulu, i-enamel noma i-polymer lining eqinisekisiwe inikeza umgoqo owengeziwe ongasebenzi.
Ingabe i-silo ingenziwa ngendlela eyenzelwe okusanhlamvu kwethu nemakethe yethu?
Yebo. Umthamo kanye nejiyomethri, udonga kanye nesimo sokuthintana nokudla kwe-sealant endaweni ekuyiwa kuyo, isisekelo esiyindilinga noma esicaba, ukungenisa umoya nokuphefumula, ukuqapha izinga lokushisa kanye nemibhalo yokuhambisana konke kuhlelwe ngokwesitshalo kanye nemakethe, kunikezwa ngesikhathi sokudluliselwa.
