Insimbi engagqwali esezingeni lokudla ibhekisela ezintweni zensimbi engagqwali ezihambisana ne-National Standard of the People's Republic of China / Sanitary Standards for Stainless Steel Utensil Containers GB 9684-88. Okuqukethwe kwayo kwe-lead kanye ne-chromium kuphansi kakhulu kunokwensimbi engagqwali evamile.
Uma izinsimbi ezisindayo ezithuthwa yimikhiqizo yensimbi engagqwali lapho isetshenziswa zidlula umkhawulo, kungafaka impilo yabantu engozini. Ngenxa yalokhu, i-National Food Safety Standard ye-“Stainless Steel Products” (GB9684-2011) ibeke amazinga aqinile okuna kwezinsimbi ezisindayo ezahlukahlukene njenge-chromium, i-cadmium, i-nickel, kanye ne-lead ezitsheni zokupheka. Esinye isizathu ukuthi ngokwanda kokuqukethwe kwe-manganese ensimbini engagqwali, kuba nokulahlekelwa kwemisebenzi efana nokumelana nokugqwala kanye nokumelana nokugqwala kwesitofu. Uma okuqukethwe kwe-manganese kufinyelela inani elithile, lo mkhiqizo awukwazi ukusetshenziswa njengesitofu noma awukwazi ukubizwa ngokuthi isitofu sensimbi engagqwali. Kodwa ngisho nangokuqukethwe okuphezulu kangaka kwe-manganese, ngokuvamile akukho mthelela empilweni. I-304 stainless steel iyinsimbi engagqwali evame kakhulu, ebizwa nangokuthi insimbi engagqwali engu-18-8 embonini. Ukumelana kwayo nokugqwala kungcono kune-430 stainless iron, ukumelana nokugqwala okuphezulu, kanye nokumelana nokushisa okuphezulu, ukusebenza kahle kokucubungula, ngakho-ke isetshenziswa kabanzi embonini, ekuhlobiseni ifenisha, kanye nasembonini yezokwelapha, isibonelo, ezinye izitsha zetafula zensimbi engagqwali zekhwalithi ephezulu, indlu yokugezela, izinto zasekhishini.
Ukuze kugcinwe ukumelana nokugqwala okungokwemvelo kwensimbi engagqwali, insimbi kumele ibe ne-chromium engaphezu kuka-17% kanye ne-nickel engaphezu kuka-8%. Uma kuqhathaniswa, insimbi engagqwali engu-201, 202 (eyaziwa ngokuthi insimbi ene-manganese ephezulu) ivame ukusetshenziswa emikhiqizweni yezimboni futhi ayikwazi ukusetshenziswa njengezitsha zokudla, ngoba: Okuqukethwe kwe-manganese kudlula okujwayelekile, ukudla ngokweqile kwe-manganese emzimbeni womuntu kuzobangela umonakalo ohlelweni lwezinzwa.
Empilweni yansuku zonke, sinamathuba aphezulu kakhulu okuthinta imikhiqizo yensimbi engagqwali, futhi amaketela kagesi ensimbi engagqwali angenye yawo. Kunzima ukuhlukanisa ukuthi yimaphi angama-“201″? Yimaphi angama-“304″?”
Ukuze kuhlukaniswe lezi zinto ezahlukene zensimbi engagqwali, indlela elabhorethri ngokuyinhloko iwukuthola ukwakheka kwezinto. Kunomehluko omkhulu ekwakhiweni kwensimbi kwezinto ezahlukene zensimbi engagqwali. Kubathengi abavamile, le ndlela iwubungcweti kakhulu futhi ayifaneleki, futhi efaneleka kakhulu ukusebenzisa i-ejenti yokuhlola okuqukethwe kwe-manganese engu-304. Kudingeka nje ukulahla phezu kobuso ukuze kutholakale ukuthi izinto zinokuqukethwe kwe-manganese okungaphezu kwesilinganiso, ngaleyo ndlela kuhlukaniswe insimbi engagqwali engu-201 kanye nensimbi engagqwali engu-304. Futhi ngomehluko phakathi kwensimbi engagqwali evamile engu-304 kanye nensimbi engagqwali yokudla, kudingeka ukuhlolwa kwelabhorethri okuningiliziwe ukuze kuhlukaniswe. Kodwa sidinga ukwazi ukuthi ukwakheka kwensimbi engagqwali yokudla yikho okuqinile kakhulu, kuyilapho insimbi engagqwali yezimboni ilula kakhulu.
Izinto ezihlangabezana nesitifiketi esijwayelekile se-GB9684 sikazwelonke futhi ezingathintana nokudla ngaphandle kokulimaza umzimba. Insimbi engagqwali ye-GB9864 iyinto yensimbi engagqwali ehlangabezana nesitifiketi esijwayelekile se-GB9684 sikazwelonke, ngakho-ke insimbi engagqwali ye-GB9864 ayidingi insimbi engagqwali yezinga lokudla. Ngesikhathi esifanayo, lokho okubizwa ngokuthi insimbi engagqwali ye-304 akudingeki ukuthi kuqinisekiswe yisimiso se-GB9684 sikazwelonke. Insimbi engagqwali ye-304 ayilingani nensimbi engagqwali yezinga lokudla. Insimbi engagqwali ye-304 ayisetshenziswa kuphela ezitsheni zasekhishini kodwa futhi isetshenziswa kabanzi embonini. Ngesikhathi sokuthenga, imikhiqizo evamile izomakwa ngokuthi “insimbi engagqwali yezinga lokudla yezinga 304” ebusweni nasodongeni lwangaphakathi lomkhiqizo, futhi imikhiqizo emakwe ngokuthi “i-food grade-GB9684” iphephile kakhulu.
