304, ndi mtundu wachitsulo chosapanga dzimbiri, dzina lachi America.Dzina lake lachi China ndi 06Cr19Ni10, lomwe ndi lovuta kwambiri komanso losavuta kuwerenga, choncho timakonda kulitcha "304 zitsulo zosapanga dzimbiri".
Kodi 304 chitsulo chosapanga dzimbiri ndi chofanana ndi chakudya kalasi 304 chitsulo chosapanga dzimbiri?Osati chimodzimodzi!Gulu lazakudya ndi mtundu, ndi za machitidwe awiri, koma pali maulalo osawerengeka.Monga mwamuna yemwe angakhoze kukhala onse mwamuna ndi tate—kodi mwamuna ayenera kukhala tate?Osati kwenikweni.

Munda wazitsulo zosapanga dzimbiri ndi womwewo, chizindikirocho chimatsimikizira kukana kwa dzimbiri kwa chitsulo chosapanga dzimbiri.Kaya ndi kalasi ya chakudya, kuwonjezera pa kukana kwa dzimbiri kwa zitsulo zosapanga dzimbiri, komanso pa lead, chromium, faifi tambala, cadmium, arsenic asanu heavy metal mpweya zizindikiro ndi zofunika.
Pambuyo pake, zidapezeka kuti chitsulo chosapanga dzimbiri chomwe chingakwaniritse zofunikira zamvula yachitsulo cholemera chikhoza kukwaniritsa zofunikira za mtunduwo.Choncho mu dziko muyezo GB9684-2011 "miyezo dziko chitetezo chakudya chakudya Chofunika cha mankhwala zosapanga dzimbiri zitsulo, ndi zinathetsedwa, zimangofunika heavy metal mafunsidwe (kusinthidwa njira ina, koma kwenikweni ndi JiuGuo chizindikiro pafupifupi), kotero masiku ano ntchito zosapanga dzimbiri tableware, ndi cholakwika ndi zofunika mtundu, koma nthawi yomweyo, malinga ngati angathe kukwaniritsa chakudya kalasi, Ayenera kukwaniritsa osachepera 304 mlingo zosapanga dzimbiri.

Tsopano, chakudya kalasi 304 zitsulo zosapanga dzimbiri ndi 304 zitsulo zosapanga dzimbiri kuti akwaniritse muyeso wa mpweya wa heavy metal;Ndipo chitsulo chosapanga dzimbiri cha 304 sichimayesedwa ndi GB 9684.
Dzina la NATIONAL standard GB 9684 ndi National Standard for Food Safety Stainless Steel Products.Muyezo wadziko lino wasinthidwa mu 2017 ndi GB 4806.9-2016 National Standard for Food Safety metallic Materials and Products omwe amagwiritsidwa ntchito mu Food Contact (muyezo watsopanowu umaphatikiza mfundo ziwiri zoyambirira za dziko zomwe zimagwira ntchito kuzitsulo zosapanga dzimbiri (GB 9684) ndi aluminiyamu (GB 11333) ).

Ndiko kuti, chakudya kalasi zosapanga dzimbiri zitsulo mogwirizana ndi dziko kuvomerezedwa muyezo GB4806.9-2016 "Chakudya chitetezo dziko muyezo chakudya kukhudzana ndi zitsulo ndi mankhwala" zitsulo zosapanga dzimbiri.
Ponena za zida zazitsulo zosapanga dzimbiri, mulingo watsopano wa NATIONAL (GB 4806.9) umanena kuti:
4.1.3 Ziwiya zazitsulo zosapanga dzimbiri ziyenera kupangidwa ndi chitsulo chosapanga dzimbiri cha austenitic, chitsulo chosapanga dzimbiri cha austenitic ferritic, chitsulo chosapanga dzimbiri ndi zinthu zina zosapanga dzimbiri;
Mulingo wa NATIONAL uwu, popereka mayeso oyesa kusamuka, amayika zida zachitsulo zosapanga dzimbiri munjira yoyeserera yazakudya (nthawi zambiri acidic solution) kuti amizidwe, atatha kuyesedwa kwanthawi yodziwika ngati pali zinthu zina mu yankho, monga momwe tawonetsera patebulo lotsatirali.

Monga momwe tawonera patebulo, zinthu zovulaza zimaphatikizapo arsenic, cadmium, lead, chromium, faifi tambala ndi zinthu zina zisanu, bola ngati zinthu zisanu zomwe zili muyeso yoyeserera sizikupitilira mtengo womwe watchulidwa patebulo, mutha kulengeza kuti izi. gulu la zinthu ndi chakudya kalasi zosapanga dzimbiri zitsulo.
Tili mu kugula tableware (kwenikweni anati "tableware" si muyezo ndithu, ayenera kukhala "Stainless zitsulo kukhudzana chakudya"), ayenera makamaka kuona ma CD ake ali "GB4806.9-2016" mawu, pokha pozindikira mankhwala, tikhoza kukhala otsimikiza kugula.

Mwa njira: zinthu zina zazitsulo zosapanga dzimbiri zidzasewera "chakudya cha 304" chisindikizo chachitsulo, kwenikweni, timadziwa ubongo pang'ono, "304" palokha si dzina lachi China, kodi chisindikizochi chingakhale bwanji ulamuliro wa chizindikiritso?
Zolemba zoterezi zikadali chinthu chosavomerezeka, ndipo palibe "zolemba" zovomerezeka mu Standard.Ndime 4 yokha "Zina" imatanthawuza kuyika zilembo m'mawu oyamba.4.1: "Kukhudzana ndi chakudya" kudzalembedwa pazogulitsa kapena phukusi locheperako.Palibe malangizo kapena zowonjezera.
Choncho kaya pali sitampu kapena ayi, sitiyenera kuweruza khalidwe la zitsulo zosapanga dzimbiri.Komabe chiganizo chimenecho, onani ngati pali "GB4806.9-2016" pa phukusi, yodalirika kwambiri.

Chitsulo chosapanga dzimbiri cha chakudya chimakhala ndi zitsulo zosapanga dzimbiri 304 ndi zitsulo zosapanga dzimbiri 316
1. 304 chitsulo chosapanga dzimbiri chimatha kukana dzimbiri ndi makutidwe ndi okosijeni a zinthu zama mankhwala.Zomwe zimagwiritsidwa ntchito pophika zitsulo zosapanga dzimbiri zili pamwamba pa 304. 2, 316 zitsulo zosapanga dzimbiri zili bwino, zili ndi faifi tambala 10%, kukana dzimbiri, zomwe zimagwiritsidwa ntchito kwambiri pazachipatala, palibe mpweya wazitsulo wachitsulo, wotetezeka kwambiri.

Chakudya kalasi 304 ndi SUS304 kusiyana kwachitsulo chosapanga dzimbiri
SUS304 amatanthauza 304 zitsulo zosapanga dzimbiri.SUS ndi muyezo wakuthupi waku Japan, 304 chitsulo chosapanga dzimbiri chimapangidwa molingana ndi muyezo waku America ASTM wa mtundu wachitsulo chosapanga dzimbiri.304 ndi yofanana ndi chitsulo chosapanga dzimbiri cha 06Cr19Ni10 cha ku China, Japan idatchulanso dzina la United States, lotchedwa: SUS304.SUS304 sikuti ndi chitsulo chosapanga dzimbiri, ichi ndi chizindikiro cha ku Japan.

Zomwe zimatchedwa "chakudya kalasi", "kalasi ya ndege", "kalasi yachipatala" kapena mawu ofanana, akugwirizana ndi miyezo ya dziko, ingoyang'anani zitsulo ndipo simungathe kudziwa kuti ndi "XX kalasi" monga 304 zitsulo zosapanga dzimbiri zokha. imayimira chitsulo chogwirizana ndi ntchito ya 304 zitsulo zosapanga dzimbiri pamtundu wa dziko, Pokhapokha mogwirizana ndi dziko lonse (GB 4806.9-2016 National Food Safety miyezo ya zakudya kukhudzana ndi zitsulo ndi mankhwala) 304 zitsulo zosapanga dzimbiri ndi zenizeni " chakudya” zitsulo zosapanga dzimbiri.
Chachitatu, ngakhale zopangira zimagwiritsa ntchito chitsulo chosapanga dzimbiri cha chakudya chenicheni, koma chomaliza chimatha kufikira "kalasi yachakudya" ikufunikabe kuwona kuchuluka kwa kukonza ndi zida zakunja, zonse zomwe zikugwirizana ndi miyezo yadziko yazinthu ndizotetezeka. "chakudya kalasi" zitsulo zosapanga dzimbiri.

Kuphatikiza apo, kalasi ya 304 chitsulo chosapanga dzimbiri iyenera kuzindikirika, chifukwa molingana ndi kalasi / chiyambi / malinga ndi miyezo yosiyana, kapangidwe kazinthu zenizeni ndi zinthu zakuthupi zimasinthidwa.
