304, luhlobo lwentsimbi engatyiwayo, igama laseMelika.Igama layo lesiShayina liyi-06Cr19Ni10, enzima kakhulu kwaye kunzima ukuyifunda, ngoko sikhetha ukuyibiza ngokuthi "304 insimbi engenasici".
Ngaba i-304 insimbi engenastainless iyafana nebakala lokutya 304 intsimbi engatyiwayo?Akunjalo!Ibakala lokutya kunye nebhrendi, yeyeenkqubo ezimbini, kodwa kukho amakhonkco angenakubalwa.Njengendoda enokuba yindoda noyise—ingaba indoda ingaba nguyise na?Akunjalo.

Intsimi yensimbi engenasici iyafana, uphawu lumisela ukuxhatshazwa kwe-corrosion yensimbi engenasici.Nokuba libakala lokutya, ukongeza kwi-corrosion resistance ye-stainless steel, kodwa nakwi lead, i-chromium, i-nickel, i-cadmium, i-arsenic izalathisi ezintlanu zentsimbi enzima zineemfuno.
Kamva, kwafunyaniswa ukuba insimbi engenasici enokuthi ihlangabezane neemfuno zemvula yensimbi enzima inokuhlangabezana neemfuno ze-brand.Ngoko kumgangatho wesizwe GB9684-2011 "imigangatho yokhuseleko lokutya yesizwe Imfuneko iimveliso zentsimbi, irhoxisiwe, kufuna kuphela ukubekwa metal enzima (itshintshe enye indlela, kodwa eneneni kwaye JiuGuo uphawu phantse), ngoko esetyenziswa namhlanje tableware steel stainless, kuba engalunganga kwiimfuno ze-brand, kodwa kwangaxeshanye, ukuba nje ikwazi ukufikelela kwibakala lokutya, Kufuneka ikwazi ukufikelela ubuncinci be-304 inqanaba lensimbi engenasici.

Ngoku, ibakala lokutya le-304 insimbi engenasici i-304 insimbi engenasici ukuhlangabezana nomgangatho wemvula enzima;Kwaye intsimbi ye-304 eqhelekileyo, ayivavanywa yi-GB 9684.
Igama lomgangatho we-NATIONAL we-GB 9684 nguMgangatho weSizwe woKhuseleko lokuTya kweeMveliso zeNtsimbi ezingenasici.Lo mgangatho kazwelonke uthatyathelwe indawo kwi-2017 nge-GB 4806.9-2016 iMigangatho yeSizwe yoKhuseleko lokuTya kwiZibonelelo zetsimbi kunye neeMveliso ezisetyenziselwa uQhagamshelwano lokuTya (lo mgangatho omtsha udibanisa imigangatho emibini yokuqala yelizwe esebenzayo kwinsimbi engenasici (GB 9684) kunye ne-aluminium (GB 11333) ).

Oko kukuthi, ibakala lokutya lensimbi engenasici lihambelana nomgangatho ogunyazisiweyo wesizwe we-GB4806.9-2016 "Ukhuseleko lokutya oluqhelekileyo lwelizwe loqhagamshelwano lokutya kunye nezixhobo zetsimbi kunye neemveliso" zensimbi engenasici.
Ngokumalunga neetafile zensimbi engenasici, umgangatho omtsha we-NATIONAL (GB 4806.9) uyacacisa:
4.1.3 Izikhongozeli zensimbi ezingenasici kufuneka zenziwe nge-austenitic stainless steel, i-austenitic ferritic stainless steel, i-ferritic stainless steel kunye nezinye izinto zensimbi;
Kulo mgangatho WESIZWE, ukunikezelwa kovavanyo lokufuduka, ukubeka izinto zensimbi ezingenasici kwisisombululo sokutya esifanisiweyo (isisombululo esine-acidic ngokubanzi) sokucwiliswa, emva kokufikelela kuvavanyo lwexesha elichaziweyo ukuba kukho izinto ezithile kwisisombululo, njengoko kuboniswe kwitheyibhile elandelayo.

Njengoko kunokubonwa kwitheyibhile, izinto ezinobungozi ziquka i-arsenic, i-cadmium, i-lead, i-chromium, i-nickel kunye nezinye izinto ezintlanu, ukuba nje izinto ezintlanu kwisisombululo sovavanyo zingagqithisi ixabiso elichaziweyo kwitheyibhile, unokuvakalisa ukuba oku ibhetshi yezinto ibakala lokutya intsimbi stainless.
Sithenga i-tableware (eneneni kuthiwa "i-tableware" ayifani ncam, kufuneka ibe "kukutya koqhagamshelwano lwensimbi engenasici"), kufuneka ibone ubukhulu becala ukupakishwa kwayo "kunamagama e-GB4806.9-2016", kuphela ngokufunyanwa kweemveliso, sinokuqiniseka ukuba sithenge.

Ngendlela: ezinye iimveliso zensimbi ezingenasici ziya kudlala "ibakala lokutya 304" intsimbi yentsimbi, enyanisweni, siyazi ingqondo encinci, "i-304" ngokwayo ayilogama lesiTshayina, ingaba eli tywina linokuba ligunya lophawu lwesiqinisekiso njani?
Ukuleyibhile okunjalo kuseyimveliso engekho semthethweni, kwaye akukho “kulebula” kusemthethweni kuMgangatho.Kuphela licandelo lesi-4 “Elinye” elibhekisa ekufakeni iilebhile kumbhalo wokuqala.4.1: "Uqhagamshelwano lokutya" luya kubhalwa kwimveliso okanye ubuncinane bephakheji yokuthengisa.Akukho miyalelo okanye izinto ezongezelelweyo.
Ngoko ke nokuba sikhona okanye singekho esi sitampu, akufuneki sigwebe umgangatho wensimbi engenasici ngokulandelelana.Okwangoku eso sivakalisi, bona ukuba kukho "GB4806.9-2016" kwiphakheji, eyona nto inokuthenjwa.

Ibakala lokutya intsimbi estainless ikakhulu ine 304 stainless steel kunye 316 stainless steel
1. I-304 insimbi engenasici inokuxhathisa ukubola kunye ne-oxidation yezinto zekhemikhali.Izinto eziqhelekileyo zensimbi engenastainless yoxinzelelo lwe-cooker ingaphezulu kwe-304. 2, 316 insimbi engenasici ingcono, iqulethe i-nickel ye-10%, ukuxhathisa ukubola, isetyenziswe ngokubanzi kwezonyango, akukho mvula ye-ion zetsimbi, ikhuselekile kakhulu.

Ibanga lokutya 304 kunye SUS304 umahluko steel stainless
I-SUS304 ibhekisa kwi-304 yentsimbi engatyiwayo.I-SUS ngumgangatho wezinto zaseJapan, i-304 insimbi engenasici iveliswa ngokuhambelana nomgangatho we-ASTM waseMelika we-brand of steel stainless.I-304 ilingana ne-China ye-06Cr19Ni10 yensimbi engenasici, iJapan nayo yakhankanya i-United States yegama, ebizwa ngokuba yi-SUS304.I-SUS304 ayisiyiyo ibakala lokutya, le yileyibhile yaseJapan.

Okubizwa ngokuba "ibakala lokutya", "ibakala le-aviation", "ibakala lezonyango" okanye amagama afanayo, ahambelana nemigangatho kazwelonke, jonga nje intsimbi kwaye awukwazi ukumisela oku "ibakala XX" njenge-304 yensimbi engenasici kuphela. imele intsimbi ngokuhambelana nokusebenza kwe-304 yensimbi engenasici kumgangatho wesizwe, Kuphela ngokuhambelana nomgangatho wesizwe (i-GB 4806.9-2016 imigangatho yoKhuseleko lokuTya kweSizwe kwizinto zokudibanisa ukutya kunye nemveliso) i-304 insimbi engenasici yinyani " ukutya grade” steel stainless.
Okwesithathu, nokuba izinto eziluhlaza zisebenzisa ibakala lokutya lokwenene insimbi engenasici, kodwa imveliso yokugqibela inokufikelela "kwibakala lokutya" kusafuneka ibone inqanaba lokucubungula kunye nezinto zangaphandle, kuphela zonke ezihambelana nemigangatho yesizwe yemveliso ikhuselekile. "Ibakala lokutya" iimveliso zensimbi ezingenasici.

Ukongezelela, ibakala le-304 yensimbi engenasici iya kuhlukaniswa, kuba ngokwebakala / imvelaphi / ngokwemigangatho eyahlukeneyo, ukubunjwa kwezinto ezithile kunye neempawu ezibonakalayo zitshintshwa.
