Intsimbi engatyiwayo yodidi lokutya ibhekisa kwizixhobo zentsimbi engatyiwayo ezihambelana neMigangatho yeSizwe yeRiphabliki yabantu baseTshayina / iMigangatho yoBucoceko yeeContainers zeZinto zeNtsimbi engatyiwayo GB 9684-88. Umxholo wayo welothe kunye ne-chromium uphantsi kakhulu kunowentsimbi engatyiwayo iyonke.
Xa iintsimbi ezinzima ezifuduselwa ziimveliso zentsimbi engagqwali xa zisetyenziswa zidlula umda, oku kunokubangela impilo yabantu emngciphekweni. Ngenxa yesi sizathu, uMgangatho weSizwe woKhuseleko lokutya we "Stainless Steel Products" (GB9684-2011) ubeke imigangatho engqongqo yokunciphisa iintsimbi ezinzima ezahlukeneyo ezifana ne-chromium, i-cadmium, i-nickel, kunye ne-lead kwizixhobo zokupheka. Esinye isizathu kukuba ngokwanda komxholo we-manganese kwintsimbi engagqwali, kukho ukulahleka kwemisebenzi efana nokumelana nokugqwala kunye nokumelana nokugqwala kwesitofu. Nje ukuba umxholo we-manganese ufikelele kwixabiso elithile, le mveliso ayinakusetyenziswa njengesitofu okanye ayinakubizwa ngokuba sisitofu sentsimbi engagqwali. Kodwa nangona umxholo we-manganese uphezulu kangaka, ngokubanzi akukho mpembelelo kwimpilo. I-304 stainless steel yintsimbi engagqwali eqhelekileyo kakhulu, ekwabizwa ngokuba yi-18-8 stainless steel kushishino. Ukumelana kwayo nokugqwala kungcono kune-430 stainless steel, ukumelana nokugqwala okuphezulu, kunye nokumelana nobushushu obuphezulu, ukusebenza kakuhle kokucubungula, ngoko ke isetyenziswa kakhulu kushishino, ukuhombisa ifenitshala, kunye noshishino lwezonyango, umzekelo, ezinye izitya zetafile zentsimbi engagqwali ezikumgangatho ophezulu, igumbi lokuhlambela, izixhobo zasekhitshini.
Ukuze intsimbi engagqwaliyo ihlale ikwazi ukumelana nokugqwala, intsimbi kufuneka ibe ne-chromium engaphezulu kwe-17% kunye ne-nickel engaphezulu kwe-8%. Xa kuthelekiswa, intsimbi engagqwaliyo ye-201, 202 (eyaziwa ngokuba yi-high manganese steel) isetyenziswa kakhulu kwiimveliso zoshishino kwaye ayinakusetyenziswa njengezinto zokubeka etafileni, kuba: Umxholo weManganese udlula umgangatho, ukutya i-manganese kakhulu emzimbeni womntu kuya kubangela umonakalo kwinkqubo yemithambo-luvo.
Kubomi bemihla ngemihla, sinamathuba aphezulu kakhulu okuchukumisa iimveliso zentsimbi engagqwaliyo, kwaye iiketile zombane zentsimbi engagqwaliyo zezinye zazo. Kunzima ukwahlula ukuba zeziphi "ezingama-201"? Zeziphi "ezingama-304"?
Ukwahlula ezi zinto zahlukeneyo zentsimbi engagqwaliyo, indlela elabhoratri ikakhulu kukufumanisa ukwakheka kwezinto. Kukho umahluko omkhulu kwisakhiwo sesinyithi sezinto ezahlukeneyo zentsimbi engagqwaliyo. Kubathengi abaqhelekileyo, le ndlela inobuchule kakhulu kwaye ayifanelekanga, kwaye eyona ifanelekileyo kukusebenzisa iarhente yovavanyo lomxholo we-manganese engama-304. Kufuneka ulahle kuphela phezu komphezulu ukuze ubone ukuba izinto zinomxholo we-manganese odlula umgangatho, ngaloo ndlela ukwahlula intsimbi engagqwali engama-201 kunye nentsimbi engagqwali engama-304. Kwaye umahluko phakathi kwentsimbi engagqwaliyo eqhelekileyo engama-304 kunye nentsimbi engagqwaliyo yokutya, kufuneka uvavanyo lwelabhoratri oluneenkcukacha ngakumbi ukuze kwahlulwe. Kodwa kufuneka sazi ukuba ukwakheka kwentsimbi engagqwaliyo yokutya yeyona ingqongqo, ngelixa intsimbi engagqwaliyo yemizi-mveliso ilula kakhulu.
Izinto ezihambelana nesiqinisekiso selizwe se-GB9684 kwaye zinokudibana nokutya ngaphandle kokubangela ingozi emzimbeni. I-GB9864 stainless steel sisixhobo sensimbi esingenasici esihambelana nesiqinisekiso selizwe se-GB9684, ngoko ke i-GB9864 stainless steel ayifuni ukuba iqinisekiswe ngumgangatho wesizwe we-GB9684. I-304 stainless steel ayilingani ne-304 stainless steel stainless steel. I-304 stainless steel ayisetyenziswa kuphela kwizixhobo zasekhitshini kodwa ikwasetyenziswa kakhulu kushishino. Ngexesha lokuthenga, iimveliso eziqhelekileyo ziya kuphawulwa "ngentsimbi engagqwali yokutya ye-304" kumphezulu nangaphakathi kodonga lwemveliso, kwaye iimveliso eziphawulwe "nge-food grade-GB9684" zikhuselekile ngakumbi.
