304, imhando yesimbi isina tsvina, zita reAmerica.Zita rayo reChinese brand 06Cr19Ni10, iyo yakaoma uye yakaoma kuverenga, saka isu tinosarudza kuidaidza kuti "304 simbi isina tsvina".
Ko 304 simbi isina tsvina yakafanana negiredhi rekudya 304 simbi isina tsvina?Hazvina kufanana!Chikafu giredhi uye mhando, ndeye maviri masisitimu, asi kune zvisingaverengeke zvinongedzo.Somurume anogona kuva zvose murume uye baba - murume anofanira kuva baba here?Kwete hazvo.

Stainless simbi munda wakafanana, mucherechedzo unosarudza kushorwa kwesimbi yesimbi isina tsvina.Ingave giredhi yechikafu, mukuwedzera kune kushora kwesimbi yesimbi inodiwa, asiwo pamutobvu, chromium, nickel, cadmium, arsenic shanu inorema simbi kunaya zviratidzo zvine zvinodiwa.
Gare gare, zvakaonekwa kuti simbi isina tsvina inogona kusangana nezvinodiwa zvekunaya kwesimbi inorema inogona kusangana nezvinodiwa zvechiratidzo.Saka munyika mureza GB9684-2011 "nyika zvokudya kuchengeteka mitemo Zvinodiwa Stainless simbi zvigadzirwa, inokanzurwa, chete zvinoda heavy metal deposition (yakachinjwa neimwe nzira, asi chaizvoizvo uye JiuGuo mucherechedzo anenge), saka nhasi kushandiswa Stainless simbi tableware, zviri. zvisiri izvo kune zvinodiwa nemhando, asi panguva imwe chete, chero bedzi ichikwanisa kuwana chikafu chegiredhi, Inofanirwa kukwanisa kuwana kanenge 304 simbi isina tsvina.

Ikozvino, chikafu chegiredhi 304 simbi isina simbi 304 simbi isina simbi kuti isangane nechiyero chekunaya kwesimbi inorema;Uye yakajairwa 304 simbi isina tsvina, haina kuedzwa neGB 9684.
Iro zita rekare NATIONAL standard GB 9684 ndiyo National Standard yeChikafu Chengetedza Stainless Simbi Zvigadzirwa.Iyi chiyero chenyika chakatsiviwa muna 2017 neGB 4806.9-2016 National Standard yeChikafu Chengetedza simbi Zvishandiso uye Zvigadzirwa zvinoshandiswa muChikafu Kubata (iyi chiyero chitsva chinosanganisa zviyero zviviri zvekutanga zvepasirese zvinoshanda kusimbi isina tsvina (GB 9684) nealuminium (GB 11333) )

Kureva kuti, chikafu giredhi Stainless simbi inoenderana nenyika inosungirwa mwero GB4806.9-2016 "Chikafu chekuchengetedza nyika chiyero chekudya kusangana nezvinhu zvesimbi uye zvigadzirwa" simbi isina tsvina.
Nezve simbi isina tsvina tableware, iyo itsva NATIONAL mwero (GB 4806.9) inoti:
4.1.3 Midziyo yemidziyo yesimbi isina tsvina inofanira kugadzirwa neaustenitic stainless steel, austenitic ferritic stainless steel, ferritic stainless steel nezvimwe zvinhu simbi isina tsvina;
Mune iyi NATIONAL mwero, kupihwa kwekuyedzwa kwekutama, isa simbi isina tsvina mune inofananidzwa chikafu chemhinduro (kazhinji acidic solution) yekunyudzwa, mushure mekusvika panguva yakatarwa bvunzo kana paine zvimwe zvinhu mumhinduro, sezvakaratidzwa mutafura inotevera.

Sezvinoonekwa kubva patafura, zvinhu zvinokuvadza zvinosanganisira arsenic, cadmium, lead, chromium, nickel uye zvimwe zvishanu zvinhu, chero zvinhu zvishanu mumhinduro yebvunzo zvisingapfuure kukosha kwakatarwa patafura, unogona kutaura kuti izvi. batch of material is food grade Stainless steel.
Isu tiri mukutenga tableware (chaizvoizvo yakanzi "tableware" haina kunyatso chiyero, inofanira kunge iri "stainless simbi yekubata chikafu"), inofanira kunyanya kuona kurongedza kwayo kune "GB4806.9-2016" mazwi, kuburikidza nekuonekwa kwezvigadzirwa, tinogona kuzorora kuvimbiswa kutenga.

Sezvineiwo: zvimwe zvigadzirwa zvesimbi isina tsvina zvinotamba "chikafu giredhi 304" simbi chisimbiso, kutaura zvazviri, isu tinoziva huropi hudiki, "304" pachayo harisi zita reChinese, chisimbiso ichi chingave sei chiremera chechiratidzo chechiratidzo?
Kunyora kwakadaro kuchiri chigadzirwa chisina pamutemo, uye hapana "chinyorwa" chepamutemo muStandard.Chikamu chechina chete "Zvimwe" chinoreva kuisa mazita muzvinyorwa zvepakutanga.4.1: "Chikafu chekubata" chichanyorwa pachigadzirwa kana pasuru yekutengesa pasuru.Hapana mirairo kana zvimwe zvinhu.
Saka kana paine chitambi ichi kana kuti kwete, hatifanire kutonga kunaka kwesimbi isina tsvina.Zvakadaro mutsara iwoyo, ona kana paine "GB4806.9-2016" pasuru, iyo yakavimbika kwazvo.

Chikafu giredhi Stainless simbi inonyanya kuve ne304 Stainless simbi uye 316 Stainless simbi
1. 304 simbi isina tsvina inogona kuramba kuonda uye oxidation yemakemikari zvinhu.Iyo yakajairwa zvinhu zvesimbi isina tsvina yekumanikidza cooker iri pamusoro pe304. 2, 316 simbi isina tsvina iri nani, ine 10% nickel, yakawanda inodzivirira ngura, inoshandiswa zvakanyanya mukurapa, hapana simbi inonaya mvura, yakachengeteka zvakanyanya.

Chikafu giredhi 304 uye SUS304 Stainless simbi musiyano
SUS304 inoreva 304 simbi isina tsvina.SUS iJapan material standard, 304 simbi isina tsvina inogadzirwa zvinoenderana neAmerican ASTM standard yemhando yesimbi isina tsvina.304 yakaenzana neChina 06Cr19Ni10 simbi isina tsvina, Japan yakataurawo United States yezita, yakadana iyo: SUS304.SUS304 haizi giredhi rekudya simbi isina tsvina, ichi chingori chinyorwa cheJapan.

Izvo zvinonzi "giredhi rekudya", "giredhi rendege", "giredhi rekurapa" kana mazwi akafanana, anoenderana nemitemo yenyika, ingotarisa simbi uye haugone kuona iyi "XX giredhi" senge 304 simbi isina tsvina chete. inomiririra simbi inoenderana nekushanda kweiyo 304 simbi isina tsvina muyero yenyika, Chete zvinoenderana neyakajairwa yenyika (GB 4806.9-2016 National Food Security zviyero zvechikafu chekubata simbi zvinhu uye zvigadzirwa) 304 Stainless simbi ndiyo chaiyo " food grade” simbi isina tsvina.
Chechitatu, kunyange kana zvinhu zvakasvibirira zvakashandisa chikafu chechokwadi chegiredhi simbi isina tsvina, asi chigadzirwa chekupedzisira chinogona kusvika "giredhi rezvokudya" richiri kuda kuona danho rekugadzirisa uye zvinhu zvekunze, chete zvose zvinoenderana nemitemo yenyika yechigadzirwa yakachengeteka. "Chikafu chegiredhi" zvigadzirwa zvesimbi isina tsvina.

Uye zvakare, iyo giredhi ye304 simbi isina simbi inosiyaniswa, nekuti zvinoenderana negiredhi / mabviro / zvinoenderana neakasiyana zviyero, iyo chaiyo yekuumbwa kwezvinhu uye zvemuviri zvimiro zvinoshandurwa.
