Insimbi engagqwali kufanele siyijwayele sonke.Ezimpilweni zethu, izinto eziningi kakhulu zenziwe ngensimbi engagqwali.Uma sithenga imikhiqizo yasendlini yensimbi engagqwali, sivame ukubona uchungechunge lwezinombolo ngaphambi kwegama elithi "insimbi engagqwali".Izinombolo ezivame kakhulu ngu-304 kanye no-316. Zisho ukuthini lezi zinombolo?Iyiphi okufanele siyikhethe?
Insimbi engagqwali ayigcini nje ngokugqwala
Sonke siyazi ukuthi ingxenye eyinhloko yensimbi iyinsimbi.Amakhemikhali ensimbi ayasebenza, futhi kulula ukusabela ngamakhemikhali nezinto ezizungezile.Ukusabela okuvame kakhulu i-oxidation, lapho i-iron ihlangana nomoya-mpilo emoyeni, owaziwa kakhulu ngokuthi ukugqwala.
Engeza ukungcola okuthile (ikakhulukazi i-chromium) ensimbi ukuze wenze insimbi engagqwali.Kodwa ikhono lensimbi engagqwali alikona nje kuphela ukulwa nokugqwala, lokhu kungabonakala egameni layo eliphelele: insimbi engagqwali ne-acid-resistant.Insimbi engagqwali ayimelani ne-oxidation kuphela, kodwa futhi imelana nokugqwala kwe-asidi.
Zonke izinsimbi ezingagqwali zimelana ne-oxidation, kodwa izinhlobo nezilinganiso zokungcola ngaphakathi zihlukile, futhi amandla okumelana nokugqwala kwe-asidi nawo ahlukile (ngezinye izikhathi sibona ukuthi ingaphezulu lensimbi engagqwali lisagqwalile ngoba ligqwaliswe yi-asidi) .Ukuze kuhlukaniswe ukumelana nokugqwala kwe-asidi kwalezi zinsimbi ezingenasici, abantu bacacise amamaki ahlukene ensimbi engagqwali.
304 insimbi engagqwali kanye 316 insimbi engagqwali
I-304 kanye ne-316 ingamabanga ensimbi engagqwali avame kakhulu ezimpilweni zethu.Singamane sikuqonde njengokuthi: uma inombolo enkulu, inamandla okumelana nokugqwala kwe-asidi yensimbi engagqwali.
Kukhona izinsimbi ezingenasici ezimelana kancane nokugqwala kwe-asidi kunensimbi engagqwali engu-304, kodwa lezo zinsimbi ezingenasici azikwazi ukuhlangabezana nezidingo zokuxhumana nokudla.Ukudla okuvamile kwansuku zonke kungase kudle insimbi engagqwali.Ayilungele insimbi engagqwali, futhi yimbi nakakhulu emzimbeni womuntu.Isibonelo, izinsimbi zensimbi ezingenasici zisebenzisa insimbi engagqwali engu-201.
Kukhona futhi izinsimbi ezingenasici ezimelana nokugqwala kwe-asidi kunensimbi engagqwali engu-316, kodwa izindleko zalezo zinsimbi ezingenasici ziphezulu kakhulu.Izinto ezingabalimaza kunzima ukuzibona empilweni, ngakho-ke asikho isidingo sokutshala imali eningi kulesi sici.
Insimbi engagqwali yezinga lokudla
Okokuqala, ngokwezinga, akucaciswanga ukuthi yiliphi ibanga lensimbi engagqwali eliyinsimbi engagqwali yezinga lokudla.Ku-"National Food Safety Standards Stainless Steel Products (GB 9684-2011)", uchungechunge lwezidingo zokumelana nokugqwala kokuthintana nokudla kwensimbi engagqwali kucacisiwe.
Kamuva, ngemva kokuqhathanisa lezi zidingo, abantu bathola ukuthi izinga elincane lensimbi engagqwali elingahlangabezana nalezi zidingo yinsimbi engagqwali engu-304.Ngakho-ke kunesisho esithi "insimbi engagqwali engu-304 iyinsimbi engagqwali yezinga lokudla".Nokho, wonke umuntu kufanele akwazi ukuqonda lapha ukuthi lesi sitatimende asinembile.Uma i-304 ingathintana nokudla, khona-ke insimbi engagqwali engu-316, ekwazi ukumelana ne-asidi nokugqwala kunensimbi engagqwali engu-304, ingaba ngcono kunensimbi engu-316.Zingasetshenziselwa ngokwemvelo ukuxhumana nokudla.
Ngakho-ke kukhona umbuzo omkhulu: Ingabe kufanele ngikhethe i-304 eshibhile yokusetshenziswa kwasekhaya noma inani eliphakeme elingu-316?
Ngensimbi engagqwali ezindaweni ezijwayelekile, ezifana nompompi, osinki, ama-rack, njll., insimbi engagqwali engu-304 yanele.Kwezinye izinsimbi ezingenasici ezisondelene kakhulu nokudla, ikakhulukazi ngokudla okuhlukahlukene, okufana ne-tableware, izinkomishi zamanzi, njll., ungakhetha ukuthintana kwensimbi engagqwali engu-316-304 nemikhiqizo yobisi, iziphuzo ze-carbonated, njll., zisazogqwala.
