Chitsulo chosapanga dzimbiri cha chakudya chimatanthawuza za zitsulo zosapanga dzimbiri zomwe zimagwirizana ndi National Standard of the People's Republic of China / Miyezo ya Sanitary for Stainless Steel Utensil Containers GB 9684-88. Mtovu wake ndi chromium ndizotsika kwambiri kuposa zachitsulo chosapanga dzimbiri.
Pamene zitsulo zolemera zomwe zopangidwa ndi zitsulo zosapanga dzimbiri zisuntha zikugwiritsidwa ntchito mopitirira malire, zikhoza kuyika thanzi la munthu pangozi. Chifukwa cha izi, National Food Safety Standard ya "Stainless Steel Products" (GB9684-2011) yakhazikitsa miyezo yokhwima ya mvula yazitsulo zolemera zosiyanasiyana monga chromium, cadmium, faifi tambala, ndi lead mu zophikira. Chifukwa chimodzi ndi chakuti pakuwonjezeka kwa manganese muzitsulo zosapanga dzimbiri, ntchito zake zimatayika monga kukana dzimbiri ndi dzimbiri la chophika. Manganese akafika pamtengo wake, mankhwalawa sangagwiritsidwe ntchito ngati chophikira kapena sangatchulidwe kuti chophika chitsulo chosapanga dzimbiri. Koma ngakhale zili ndi manganese ochuluka chonchi, nthawi zambiri sizikhudza thanzi. 304 chitsulo chosapanga dzimbiri ndi chitsulo chosapanga dzimbiri chodziwika bwino, chomwe chimatchedwanso 18-8 chitsulo chosapanga dzimbiri pamakampani. kukana kwake dzimbiri ndi bwino kuposa 430 zosapanga dzimbiri kukana, mkulu dzimbiri kukana, ndi mkulu-kutentha kukana, wabwino processing ntchito, choncho chimagwiritsidwa ntchito mu makampani, zokongoletsera mipando, ndi makampani azachipatala, mwachitsanzo, ena apamwamba zosapanga dzimbiri tableware, bafa, khitchini zipangizo.
Kuti chitsulo chosapanga dzimbiri chisawonongeke, chitsulo chiyenera kukhala ndi chromium yoposa 17% ndi faifi tambala 8%. Poyerekeza, 201, 202 chitsulo chosapanga dzimbiri (chomwe chimadziwika kuti chitsulo chachikulu cha manganese) chimagwiritsidwa ntchito m'mafakitale ndipo sichingagwiritsidwe ntchito ngati zida zapa tebulo, chifukwa: Manganese okhutira amaposa muyezo, kudya kwambiri kwa manganese m'thupi la munthu kumayambitsa kuwonongeka kwa manganese. dongosolo lamanjenje.
M'moyo watsiku ndi tsiku, timakhala ndi mwayi waukulu wolumikizana ndi zitsulo zosapanga dzimbiri, ndipo ma ketulo amagetsi osapanga dzimbiri ndi amodzi mwa iwo. Ndizovuta kusiyanitsa omwe ali "201"? Ndi ati "304"?
Kusiyanitsa zipangizo zosapanga dzimbiri zosiyanasiyana zimenezi, njira mu labotale makamaka kudziwa zikuchokera zinthu. Pali kusiyana kwakukulu muzitsulo zazitsulo zosiyanasiyana zazitsulo zosapanga dzimbiri. Kwa ogula wamba, njira iyi ndiyaukadaulo kwambiri komanso siyoyenera, ndipo yoyenera kwambiri ndikugwiritsa ntchito 304 manganese oyesa zinthu. Kungofunika kugwetsa pamwamba kuti muwone ngati zinthuzo zili ndi manganese opitilira muyezo, potero kusiyanitsa 201 chitsulo chosapanga dzimbiri ndi 304 chitsulo chosapanga dzimbiri. Ndipo pakusiyanitsa pakati pa chitsulo chosapanga dzimbiri cha 304 ndi chitsulo chosapanga dzimbiri cha chakudya, kuyezetsa mwatsatanetsatane kwa labotale kumafunika kusiyanitsa. Koma tiyenera kudziwa kuti zitsulo zosapanga dzimbiri za chakudya zimakhala zovuta kwambiri, pamene zitsulo zosapanga dzimbiri za mafakitale zimakhala zosavuta.
zinthu zomwe zimakwaniritsa chiphaso chadziko lonse cha GB9684 ndipo zimatha kukumana ndi chakudya popanda kuvulaza thupi. Chitsulo chosapanga dzimbiri cha GB9864 ndi chitsulo chosapanga dzimbiri chomwe chimakumana ndi chiphaso chamtundu wa GB9684, kotero kuti chitsulo chosapanga dzimbiri cha GB9864 ndichosapanga chakudya. Nthawi yomweyo, zomwe zimatchedwa 304 zitsulo zosapanga dzimbiri siziyenera kutsimikiziridwa ndi muyezo wadziko lonse wa GB9684. 304 chitsulo chosapanga dzimbiri sichifanana ndi chitsulo chosapanga dzimbiri cha chakudya. Chitsulo chosapanga dzimbiri cha 304 sichimangogwiritsidwa ntchito m'makitchini komanso chimagwiritsidwa ntchito kwambiri pamakampani. Panthawi yogula, zinthu zanthawi zonse zimakhala ndi "chakudya grade 304 chitsulo chosapanga dzimbiri" pamwamba ndi khoma lamkati la chinthucho, ndipo zolembedwa ndi "chakudya grade-GB9684" ndizotetezeka kwambiri.
