Chitsulo chosapanga dzimbiri chopangidwa ndi chakudya chimatanthauza zipangizo zosapanga dzimbiri zomwe zimagwirizana ndi National Standard of the People's Republic of China / Sanitary Standards for Stainless Steel Utensil Containers GB 9684-88. Kuchuluka kwa lead ndi chromium m'chitsulo chake ndi kochepa kwambiri kuposa chitsulo chosapanga dzimbiri chopangidwa ndi chitsulo.
Ngati zitsulo zolemera zomwe zitsulo zosapanga dzimbiri zimasamuka zikagwiritsidwa ntchito zipitirira malire, zitha kuyika thanzi la anthu pachiwopsezo. Chifukwa cha izi, National Food Safety Standard ya "Zitsulo Zosapanga dzimbiri" (GB9684-2011) yakhazikitsa miyezo yokhwima yokhudza kunyowa kwa zitsulo zosiyanasiyana zolemera monga chromium, cadmium, nickel, ndi lead mu zophikira. Chifukwa chimodzi ndichakuti kuchuluka kwa manganese mu chitsulo chosapanga dzimbiri kumachepa, ntchito monga kukana dzimbiri ndi kukana dzimbiri kwa chophikira. Kuchuluka kwa manganese kukafika pamtengo winawake, mankhwalawa sangagwiritsidwe ntchito ngati chophikira kapena sangatchulidwe kuti chophikira chachitsulo chosapanga dzimbiri. Koma ngakhale ndi kuchuluka kwa manganese kotere, nthawi zambiri palibe vuto lililonse paumoyo. Chitsulo chosapanga dzimbiri cha 304 ndi chitsulo chosapanga dzimbiri chodziwika bwino, chomwe chimatchedwanso chitsulo chosapanga dzimbiri cha 18-8 mumakampani. Kukana kwake dzimbiri kuli bwino kuposa chitsulo chosapanga dzimbiri cha 430, kukana dzimbiri kwambiri, komanso kukana kutentha kwambiri, magwiridwe antchito abwino, kotero chimagwiritsidwa ntchito kwambiri m'mafakitale, zokongoletsera mipando, ndi mafakitale azachipatala, mwachitsanzo, mbale zina zapamwamba zachitsulo chosapanga dzimbiri, bafa, ndi zida zakhitchini.
Kuti chitsulo chosapanga dzimbiri chikhalebe cholimba, chitsulocho chiyenera kukhala ndi chromium yoposa 17% ndi nickel yoposa 8%. Poyerekeza, chitsulo chosapanga dzimbiri cha 201, 202 (chomwe chimadziwika kuti chitsulo cha manganese chochuluka) nthawi zambiri chimagwiritsidwa ntchito m'mafakitale ndipo sichingagwiritsidwe ntchito ngati mbale zophikira, chifukwa: Kuchuluka kwa manganese m'thupi la munthu kumaposa muyezo, kudya manganese mopitirira muyeso m'thupi kungayambitse kuwonongeka kwa mitsempha.
Mu moyo watsiku ndi tsiku, tili ndi mwayi waukulu wokhudza zinthu zosapanga dzimbiri, ndipo ma ketulo amagetsi osapanga dzimbiri ndi amodzi mwa iwo. N'zovuta kusiyanitsa omwe ali "201″? Ndi ati omwe ali "304″?"
Kuti musiyanitse zinthu zosiyanasiyana zosapanga dzimbiri izi, njira yomwe imachitika mu labotale ndi yodziwira kapangidwe ka zinthu. Pali kusiyana kwakukulu pa kapangidwe ka zitsulo zosiyanasiyana za chitsulo chosapanga dzimbiri. Kwa ogula wamba, njira iyi ndi yaukadaulo kwambiri ndipo si yoyenera, ndipo yoyenera kwambiri ndikugwiritsa ntchito choyezera kuchuluka kwa manganese cha 304. Kungofunika kugwetsa pamwamba kuti mudziwe ngati zinthuzo zili ndi kuchuluka kwa manganese kopitilira muyezo, motero kusiyanitsa chitsulo chosapanga dzimbiri cha 201 ndi chitsulo chosapanga dzimbiri cha 304. Ndipo pakusiyana pakati pa chitsulo chosapanga dzimbiri cha 304 ndi chitsulo chosapanga dzimbiri cha chakudya, kuyezetsa kwatsatanetsatane kwa labotale ndikofunikira kuti musiyanitse. Koma tifunika kudziwa kuti kapangidwe ka chitsulo chosapanga dzimbiri cha chakudya ndiye kokhwima kwambiri, pomwe chitsulo chosapanga dzimbiri cha mafakitale ndi chosavuta kwambiri.
Zinthu zomwe zimagwirizana ndi satifiketi ya dziko lonse ya GB9684 ndipo zimatha kukhudzana ndi chakudya popanda kuvulaza thupi. Chitsulo chosapanga dzimbiri cha GB9864 ndi chinthu chosapanga dzimbiri chomwe chimagwirizana ndi satifiketi ya dziko lonse ya GB9684, kotero chitsulo chosapanga dzimbiri cha GB9864 ndi chosapanga dzimbiri cha chakudya. Nthawi yomweyo, chomwe chimatchedwa 304 stainless steel sichifunika kuti chitsimikizidwe ndi muyezo wa dziko lonse wa GB9684. Chitsulo chosapanga dzimbiri cha 304 sichifanana ndi chitsulo chosapanga dzimbiri cha chakudya. Chitsulo chosapanga dzimbiri cha 304 sichimagwiritsidwa ntchito kokha mu ziwiya za kukhitchini komanso chimagwiritsidwa ntchito kwambiri mumakampani. Panthawi yogula, zinthu wamba zidzalembedwa ndi "chitsulo chosapanga dzimbiri cha chakudya cha 304" pamwamba ndi mkati mwa khoma la chinthucho, ndipo zinthu zomwe zalembedwa ndi "chitsulo cha chakudya cha 304" zimakhala zotetezeka kwambiri.
