304, he momo kila kila, inoa ʻAmelika.ʻO 06Cr19Ni10 kona inoa inoa Kina, he paʻakikī a paʻakikī hoʻi e heluhelu, no laila makemake mākou e kapa iā ia "304 stainless steel".
Ua like anei ke kila kila 304 me ke kila kila 304?ʻAʻole like!No nā ʻōnaehana ʻelua ka papa meaʻai a me ka brand, akā he nui nā loulou.E like me ke kanaka hiki ke lilo i kāne a makua kāne - pono anei ke kāne he makua kāne?ʻAʻole pono.

ʻO ke kahua kila kila, ʻo ia ka mea e hoʻoholo ai i ka pale ʻana o ke kila kila.Inā he meaʻai papa, i ka hoʻohui i ka corrosion kū'ē o kuhiliʻole kila koi, akā, ma luna o ke alakai, chromium, nickel, cadmium, arsenic elima kaumaha metala precipitation nā mea e pono ai.
Ma hope mai, uaʻikeʻiaʻo ke kila kila e hiki ke hoʻokō i nā koi o ka ua metala kaumaha hiki ke hoʻokō i nā koi o ka brand.No laila, i loko o ka 'āina maʻamau GB9684-2011 "'āina meaʻai palekana hae Koi o kuhiliʻole kila huahana, ua kāpaeʻia, wale koi kaumaha metala deposition (hoololi 'ē aʻe ala, akā, ua maoli a me JiuGuo hoailona kokoke), no laila, i keia la i hoʻohana kuhiliʻole papa tableware, ia. hewa i ka hōʻailona koi, akā i ka manawa like, i ka manawa e hiki ai ke hoʻokō i ka papa meaʻai, Pono e hiki ke hoʻokō ma ka liʻiliʻi loa 304 pae kila.

I kēia manawa, ʻo ka meaʻai 304 stainless steel he 304 stainless steel e hoʻokō i ke kūlana o ka ua metala kaumaha;A ʻo ke kila kila 304 maʻamau, ʻaʻole i hoʻāʻo ʻia e GB 9684.
ʻO ka inoa o ka maʻamau NATIONAL kahiko GB 9684 ka National Standard for Food Safety stainless Steel Products.Ua hoʻololi ʻia kēia kūlana aupuni i ka makahiki 2017 e GB 4806.9-2016 National Standard for Food Safety Metallic Materials and Products i hoʻohana ʻia ma Food Contact (ua hui pū kēia maʻamau hou i nā kūlana ʻāina ʻelua e pili ana i ke kila kila (GB 9684) a me ka alumini (GB 11333) ).

ʻO ia hoʻi, ka meaʻai meaʻai kuhiliʻole kila ma ka laina me ke aupuni mandatory maʻamau GB4806.9-2016 "Food palekana aupuni maʻamau pili meaʻai me nā mea metala a me nā huahana" kuhiliʻole kila.
E pili ana i ka papa ʻaina stainless steel, ʻo ke kūlana NATIONAL hou (GB 4806.9) e ʻōlelo nei:
4.1.3 Pono e hana ʻia nā ipu hao hao me ke kila kuhiliʻole austenitic, ke kila kuhili ʻole austenitic, ke kila kuhili ʻole ferritic a me nā mea kila ʻē aʻe;
Ma kēia kūlana NATIONAL, ka hāʻawi ʻana i kahi hoʻāʻo neʻe, e hoʻokomo i nā mea kila kila i loko o kahi hopena meaʻai simulated (generally acidic solution) no ka hoʻomaʻamaʻa ʻana, ma hope o ka hōʻea ʻana i ka hōʻike manawa i ʻōlelo ʻia inā aia kekahi mau mea i loko o ka hopena, e like me ka hōʻike ʻana ma ka papa aʻe.

E like me ka mea i ʻike ʻia mai ka papaʻaina, ʻo nā mea ʻino e pili ana i ka arsenic, cadmium, lead, chromium, nickel a me nā mea ʻelima ʻē aʻe, ʻoiai ʻaʻole i ʻoi aku nā mea ʻelima i ka hopena hoʻāʻo ma mua o ka waiwai i kuhikuhi ʻia i ka papaʻaina, hiki iā ʻoe ke haʻi i kēia. ʻO ka pūʻulu o nā mea he kila kuhili ʻole meaʻai.
Aia mākou i ke kūʻai ʻana i nā papa ʻaina (ʻoiaʻiʻo, ʻaʻole i maʻamau ka "tableware", pono ʻo "stainless steel contact food"), pono e ʻike nui ʻia i kāna pahu i loaʻa nā huaʻōlelo "GB4806.9-2016", ma o ka ʻike ʻana o nā huahana. hiki iā mākou ke hōʻoluʻolu e kūʻai.

Ma ke ala: e pāʻani kekahi mau mea kila kila i ka "ʻai meaʻai 304" sila kila, ʻoiaʻiʻo, ʻike mākou i kahi lolo liʻiliʻi, "304" ʻaʻole ia ka inoa Kina, pehea lā e lilo ai kēia sila i mana o ka hōʻailona hōʻoia?
He huahana kūʻokoʻa ʻole ia lepili ʻana, a ʻaʻohe "labelling" kūhelu ma ka Standard.ʻO ka pauku 4 wale nō "'ē aʻe" e pili ana i ka lepili ʻana ma ka kikokikona kumu.4.1: E hoʻopaʻa inoa ʻia ka "pili meaʻai" ma ka huahana a i ʻole ka pūʻolo kūʻai liʻiliʻi.ʻAʻohe ʻōlelo aʻo a i ʻole nā ​​​​mea ʻē aʻe.
No laila inā loaʻa kēia peʻa a ʻaʻole paha, ʻaʻole pono mākou e noʻonoʻo i ka maikaʻi o ke kila kila.Eia nō naʻe kēlā ʻōlelo, e ʻike inā aia he "GB4806.9-2016" ma ka pūʻolo, ʻo ka mea hilinaʻi loa.

ʻO ke kila kuhiliʻole ka nui o ka meaʻai he 304 kila kila a me 316 kila kila
1. Hiki i ka 304 ke kila kila ke pale aku i ka corrosion a me ka oxidation o nā mea kemika.ʻO ka mea maʻamau o ke kīʻaha kīʻaha kila kila ma luna o 304. 2, 316 ʻoi aku ka maikaʻi o ke kila kila, loaʻa ka 10% nickel, ʻoi aku ka pale ʻana i ka corrosion, hoʻohana nui ʻia i ka lāʻau lapaʻau, ʻaʻohe ua metala ion, palekana loa.

ʻO ka ʻokoʻa kila kuhili ʻole ka papa meaʻai 304 a me SUS304
SUS304 e pili ana i 304 kila kila.ʻO SUS kahi maʻamau o Iapana, 304 mea kila kila i hana ʻia e like me ka maʻamau ʻAmelika ASTM o kahi hōʻailona o ke kila kila.Ua like ka 304 me ka 06Cr19Ni10 stainless steel o Kina, ua haʻi pū ʻo Iapana i ka United States o ka inoa, i kapa ʻia: SUS304.ʻAʻole pono ka SUS304 i ke kila kila kila, he lepili Kepani wale nō kēia.

ʻO ka mea i kapa ʻia ʻo "food grade", "aviation grade", "medical grade" a i ʻole nā ​​​​huaʻōlelo like, e pili ana i nā kūlana aupuni, e nānā wale i ke kila a ʻaʻole hiki ke hoʻoholo ʻo ia ka "XX grade" e like me 304 stainless steel wale nō. hōʻike i ke kila ma ka laina me ka hana o ka 304 kuhiliʻole kila maʻamau i ka lahui hae, wale ma ka laina me ka lahui hae (GB 4806.9-2016 National Food Palekana nā kūlana no ka meaʻai pili metala mea a me nā huahana) 304 kuhiliʻole kila maoli " meaʻai” kila kuhiliʻole.
ʻO ke kolu, ʻoiai inā hoʻohana nā mea maka i ke kila kila kila maoli, akā hiki i ka huahana hope ke hōʻea i ka "meaʻai" pono e ʻike i ka pae hana a me nā mea o waho, ʻo nā mea āpau e pili ana i nā kūlana aupuni o ka huahana palekana. "meaʻai papa" huahana kila kuhiliʻole.

Eia kekahi, e hoʻokaʻawale ʻia ka papa o 304 stainless steel, no ka mea, e like me ka papa / kumu / e like me nā kūlana like ʻole, hoʻololi ʻia ke ʻano mea kikoʻī a me nā waiwai kino.
