Ingabe ama-GFS Silos Agunyaziwe Ngezinga Lokudla?
Kwadalwa ngo Ngokwamukisa
Ingabe Ama-Silos E-GFS Aqinisekisiwe Njengokudla?
Ukusanhlamvu kuwukudla, futhi lelo qiniso elilodwa liqhuba imfuneko abathengi abaningi bezinqolobane abayithola sekwephuzile: indawo emanzi yesinqolobane iyindawo ethintana nokudla. Insimbi egalwe nge-zinc iphakamisa umbuzo othile lapha, ngoba i-zinc iyinsimbi engakwazi ukudlulela, futhi izimiso zokuthintana nokudla zibeka imikhawulo kulokho ncamashi. Isinqolobane esiphelele ngesakhiwo singahluleka ukuhlolwa kokuphepha kokudla ngokungahambisani nezinto ezisetshenziswayo.
Udonga lwengilazi ehlanganiswe nensimbi lusingatha lokhu kahle, ngoba ingilazi evuthiwe ayisebenzi futhi ayifaki lutho emkhiqizweni. Kodwa ukungasebenzi kuyisici, hhayi isitifiketi - isitifiketi kufanele sibhalwe phansi, futhi kufanele sihlanganise zonke izingxenye ezimanzi, kuhlanganise nesigcwalisi. I-Center Enamel ihlinzeka ngaleyo mibhalo njengephakethe hhayi njengombhalo waphansi.
1. Iyiphi Isitifiketi Esisebenza Ekugcinweni Kokusanhlamvu?
Kuncike emakethe. I-United States isebenzisa i-21 CFR, i-Europe isebenzisa uMthetho 1935/2004 ngezinhlelo zikazwelonke ezifana ne-LFGB, futhi abathengi abaningi bacela kokubili.
· I-United States - 21 CFR 175.300: Lo mthetho uqondene nokumboza okune-resin nokwe-polymeric ezindaweni ezithinta ukudla, okuyisithenjwa esisetshenziswa ekumbozeni amasilo.
· I-European Union - Regulation 1935/2004: Uhlaka lomthetho oludinga ukuthi izinto ezithinta ukudla zingadlulisi izakhi ekudleni ngamanani angabeka impilo engozini noma ashintshe ukwakheka.
· I-Germany - LFGB: Ikhodi kazwelonke yokudla nokudla kwezilwane ehlinzeka ngohlelo oluningiliziwe lokuhlola olwamukelwa kabanzi eYurophu njengobufakazi bokuthobela imithetho.
· Ukuqinisekiswa Kokuzithandela - NSF/ANSI 51: Izinga lezinto zokudla ezisetshenziswayo, eliya ngokuya licelwa abacubunguli abahlinzeka abakhiqizi bokudla abanemikhiqizo enegama.
2. Ukuqinisekiswa Kufaka Ngempela Ini?
Izinto ezimbili: ukuthi yonke into ekumbozeni ivunyelwe, nokuthi indawo eqediwe ayidlulisi into elinganisekayo ekulingiseni ukudla.
· Ukubuyekezwa Kokwakheka: Ingxenye ngayinye yokwakheka kokumboza kumele ibe into evunyelwe ukuthintana nokudla ngaphansi komthetho ofanele.
· Ukuhlolwa Kokudlulisela: Indawo elaphekile ichaywa ekulingiseni ukudla ngaphansi kwezimo ezichaziwe zesikhathi nezinga lokushisa, futhi inani elidlulisiwe lilinganiswa ngokumelene nomkhawulo wokudlulisela uwonke - ngokuvamile amamiligremu ayi-10 ngesentimitha yesikwele noma amamiligremu angama-60 ngekhilogremu.
· Zonke Izingxenye Ezimanzi: I-sealant yokuhlangana, ama-gasket, izinto zokufaka umlomo kanye nezingxenye zokukhipha kufanele zithwale ukuthobela okufanayo nokwe-panel coating.
· Izimo Zokusetshenziswa: Isitifiketi sivumelekile ezimweni ezishiwo - isikhathi sokuthintana, izinga lokushisa kanye nohlobo lokudla - ngakho qinisekisa ukuthi isitifiketi sihlanganisa umsebenzi wangempela.
3. Kufanele Ubuze Mthengisi Ini?
Amadokhumenti, hhayi izichasiso. Izinto ezine zivala umbuzo, futhi umthengisi ongakwazi ukukhiqiza lezi zinto akakawenzanga umsebenzi.
· Isitatimende Sokuthobela Esibhaliwe: Ephepheni lenkampani, sisho umthethonqubo, uhlelo lokufaka i-coating kanye nomkhiqizi.
· Umbiko Wokuhlolwa Komuntu Wesithathu: Ukuhlolwa kokufuduka noma ukukhishwa okwenziwa ilabhorethri enekhono, kushiwo indlela kanye nemiphumela.
· Izitifiketi Ze-Sealant Ne-Gasket: Imibhalo ehlukene yazo zonke izingxenye ezingezona ezensimbi ezithintana nokusanhlamvu.
· Ukulandeleka Kweqoqo: Ukuhlonza okuxhumanisa amaphaneli alethwe nokumboza okwakuhlolwe.
· Ukuhambisana Nokuhlanzwa Nokubulala Izinambuzane: Ukuqinisekiswa kokuthi ukugoqeka kuyakwazi ukumelana nenqubo yokuhlanzwa kwesiza kanye nezibulala-zinambuzane ezisetshenziswayo, ikakhulukazi i-phosphine.

Ukuqinisekiswa Kobunjiniyela Nokusekela Kwephrojekthi
Wonke ithangi elethwa yi-Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) lakhiwe ngokuya nge-AWWA D103-09 kanye ne-EN 1090 ngokuqinisekiswa kwe-finite element yomzimba, uphahla kanye nemithwalo ye-nozzle, lihlanganiswe ngezinga lokushisa elingu-820-930°C ngaphansi kokuqondisa kwe-ISO 9001 ne-ISO 45001, lihlolwe nge-holiday test ku-1500 V kuyo yonke ingaphezulu elingamaphesenti ayikhulu, futhi lihlanganiswe ngamabhawudi e-Grade 8.8 kanye ne-sealant eqinisekiswe ngumkhiqizi. Amaphakethe e-silo ezinga lokudla afaka imibhalo yokuqinisekisa ukuthi i-coating ihambisana ne-21 CFR 175.300 kanye ne-LFGB lapho kudingeka, izitifiketi ze-sealant ne-gasket zokudla, kanye nokuqinisekiswa kokuhambisana ne-phosphine fumigation kanye nezinhlelo ezijwayelekile zokuhlanzwa.
Imibuzo Ejwayelekile (FAQ)
Yisiphi isitifiketi esisebenza ekugoqekeni kwesilo sokugcina okusanhlamvu?
E-United States, i-21 CFR 175.300 yezinto zokumboza ezinhlaka ezinhlaka. E-Europe, uMthetho 1935/2004 unikeza uhlaka kanye ne-LFGB yaseJalimane inikeza uhlelo lokuhlola abathengi abaningi abalucelayo. I-NSF/ANSI 51 iyisitifiketi sokuzithandela esiya sicelwa kakhulu abacubunguli bokudla.
Yini umehluko phakathi kwe-LFGB ne-FDA?
I-FDA ingumlawuli wase-US obeka izimfuneko kodwa engaqinisekisi imikhiqizo; i-LFGB iyikhodi kazwelonke yaseJalimane enikeza uhlelo olunemininingwane, oluhlolwayo futhi yamukelwa kabanzi e-Europe njengobufakazi obusebenzayo bokuthobela ukuthintana nokudla.
Ingabe izinto zokuvala esilweni zidinga isitifiketi sezinga lokudla?
Yebo. Zonke izingxenye ezithintana nokusanhlamvu kufanele zithobele, kuhlanganise nokuvala okuhlangene, amagasket kanye nezinsimbi zokukhipha. Ukumboza kwephaneli okuqinisekisiwe nokuvala okungaqinisekisiwe kusahluleka ukuhlangabezana nemfuneko, yingakho isitifiketi sokuvala kufanele sicelwe ngokwehlukana.
Uyini ukuhlolwa kokufuduka?
Ukuhlolwa lapho ukumbozwa okwelaphekile kuchaywa ekulingiseni ukudla ngaphansi kwezimo ezichaziwe zesikhathi nezinga lokushisa, futhi inani lezinto ezidluliselwe ekulingiseni lilinganiswa ngokumelene nomkhawulo - ngokuvamile amamiligremu ayi-10 ngesentimitha yesikwele noma amamiligremu angama-60 ngekhilogremu.
