Intsimbi engatyiwayo kufuneka iqheleke kuthi sonke.Kubomi bethu, zininzi kakhulu izinto ezenziwe ngentsimbi engenasici.Xa uthengela iimveliso zensimbi ezingenasici zendlu, sinokusoloko sibona uluhlu lwamanani phambi kwegama elithi "insimbi engenasici".Awona manani axhaphakileyo ngama-304 kunye nama-316. Athetha ukuthini la manani?Yiyiphi esifanele siyikhethe?
Intsimbi engatyiwayo ayirhali nje kuphela
Sonke siyazi ukuba inxalenye ephambili yentsimbi yintsimbi.Iimpawu zeekhemikhali zentsimbi ziyasebenza, kwaye kulula ukusabela ngokwekhemikhali kunye nezinto ezingqongileyo.Eyona nto ixhaphakileyo yi-oxidation, apho i-iron idibana neoksijini esemoyeni, eyaziwa ngokuba yirusi.
Yongeza ukungcola (ikakhulu ichromium) kwintsimbi ukwenza intsimbi engatyiwa.Kodwa amandla ensimbi engenasici ayikona nje ukuchasana nokugqwala, oku kunokubonwa kwigama layo elipheleleyo: insimbi engenasici kunye ne-acid-resistant.Insimbi engenasici ayixhathisi kuphela kwi-oxidation, kodwa iyakwazi ukumelana nokubola kwe-asidi.
Zonke iintsimbi ezingenastainless ziyamelana ne-oxidation, kodwa iintlobo kunye nemilinganiselo yokungcola ngaphakathi yahlukile, kwaye ukukwazi ukuxhathisa ukubola kwe-asidi kwahlukile (ngamanye amaxesha sibona ukuba umphezulu wezinye iintsimbi ezingenasici zisenomhlwa ngenxa yokuba i-asidi idliwe) .Ukuze ukwahlula ukuxhathisa kwe-asidi ye-corrosion yezi ntsimbi ezingenasici, abantu baye bachaza amabakala ahlukeneyo ensimbi engenasici.
I-304 yensimbi engenasici kunye ne-316 yensimbi engenasici
I-304 kunye ne-316 ngamanqanaba aqhelekileyo ensimbi engenasici kubomi bethu.Sinokuyiqonda ngokulula njenge: inani elikhulu, kokukhona ukomelela kokumelana nomhlwa kweasidi yentsimbi.
Kukho iintsimbi ezinganyangekiyo ezinganyangekiyo kangako kwi-acid corrosion kune-304 steel stainless, kodwa ezo zintsimbi azikwazi ukuhlangabezana neemfuno zokutya.Ukutya okuqhelekileyo kwemihla ngemihla kunokonakalisa intsimbi engatyiwayo.Ayilunganga kwintsimbi engatyiwayo, kwaye imbi nangakumbi kumzimba womntu.Ngokomzekelo, iintsimbi zensimbi ezingenasici zisebenzisa i-201 insimbi engenasici.
Kukwakho neentsimbi ezingenastainless ezikwaziyo ukumelana ne-acid corrosion kune-316 steel stainless, kodwa iindleko zezo zintsimbi ziphezulu kakhulu.Izinto ezinokubaphazamisa kunzima ukuzibona ebomini, ngoko akuyomfuneko ukuba sityale kakhulu kulo mba.
Ibakala lokutya insimbi engenasici
Okokuqala, kumgangatho, akucaciswanga ukuba yeyiphi ibakala lensimbi engenasici ibakala lokutya lensimbi engenasici."KwimiGangatho yeSizwe yoKhuseleko lokuTya kwiMveliso yeSisimbi esingenasici (i-GB 9684-2011)", uluhlu lweemfuno zokumelana nokugqwala koqhagamshelwano lokutya olungenasici lucacisiwe.
Kamva, emva kokuthelekisa ezi mfuno, abantu bafumanisa ukuba umgangatho omncinci wensimbi engenasici onokuhlangabezana nezi mfuno yi-304 yensimbi engenasici.Ngoko kukho intetho ethi "intsimbi ye-304 i-stainless steel grade grade stainless steel".Nangona kunjalo, wonke umntu kufuneka akwazi ukuqonda apha ukuba le ngxelo ayichanekanga.Ukuba i-304 inokunxibelelana nokutya, ngoko ke i-316 insimbi engenasici, ekwazi ukumelana ne-asidi kunye ne-corrosion kune-304 yensimbi engenasici, inokuthi ngokwemvelo ibe ngcono kune-316 insimbi engenasici.Ziyakwazi ngokwemvelo ukusetyenziselwa uqhagamshelwano lokutya.
Ngoko ke kukho owona mbuzo uphambili: Ngaba ndingakhetha i-304 esezantsi kusetyenziso lwasekhaya okanye ixabiso eliphezulu lama-316?
Kwinsimbi engenasici kwiindawo eziqhelekileyo, ezifana neempompo, iisinki, iiracks, njl., i-304 insimbi engenasici yanele.Kwezinye iintsimbi ezingenastainless ezinxibelelene ngokusondeleyo nokutya, ngakumbi ngokutya okuhlukahlukeneyo, okufana netafile, iikomityi zamanzi, njl., Unokukhetha i-316 stainless steel-304 insimbi engenasici kunye neemveliso zobisi, iziselo ze-carbonated, njl. usaza kudliswa.
