◉Emphakathini wanamuhla, insimbi engagqwali isiyinto evamile futhi ebalulekile esetshenziswa kabanzi ekwakheni, ekukhiqizeni nasekuphileni kwansuku zonke. Kunezinhlobo eziningi ezahlukene zensimbi engagqwali, kuhlanganise onobuhle ezivamile ezifana 201, 304 kanye316.
Kodwa-ke, kulabo abangaziqondi izakhiwo zezinto ezibonakalayo, kulula ukudideka ngokuhlukana phakathi kwalawa mamodeli. Lesi sihloko sizochaza umehluko phakathi kwensimbi engagqwali 201, 304 kanye no-316 ukusiza abafundi baqonde kangcono amamodeli ahlukene wezinto zensimbi engagqwali futhi sinikeze iziphakamiso ezithile zokuthenga insimbi engagqwali.
◉Okokuqala, umehluko ekubunjweni kwamakhemikhali
Ukwakheka kwamakhemikhali ensimbi engagqwali kuyisici esibalulekile ekunqumeni ukusebenza nezici zayo.Insimbi engagqwali 201, 304 kanye ne-316 kukhona umehluko osobala ekubunjweni kwamakhemikhali. Insimbi engagqwali 201 iqukethe 17.5% -19.5% chromium, 3.5% -5.5% nickel, kanye 0.1% -0.5% nitrogen, kodwa akukho molybdenum.
Insimbi engagqwali 304, ngakolunye uhlangothi, iqukethe 18% -20% chromium, 8% -10.5% nickel, futhi akukho nitrogen noma molybdenum. Ngokuphambene, insimbi engagqwali 316 iqukethe 16% -18% chromium, 10% -14% nickel, futhi 2% -3% molybdenum. Kusukela ekwakhekeni kwamakhemikhali, insimbi engagqwali engu-316 inokumelana nokugqwala okuphezulu kanye nokumelana ne-asidi, ifaneleka kakhulu ukusetshenziswa kwezinye izindawo ezikhethekile kunensimbi engagqwali 201 no-304.
◉Okwesibili, umehluko wokumelana nokugqwala
Ukumelana nokugqwala kuyinkomba yokusebenza ebalulekile yensimbi engagqwali. Insimbi engagqwali 201 inokumelana nokugqwala okuhle kuma-asidi amaningi ezinto eziphilayo, ama-asidi angaphili nezixazululo zikasawoti ekamelweni lokushisa, kodwa izogqwala endaweni eqinile ye-alkali. Insimbi engagqwali engu-304 inokumelana nokugqwala okuhle futhi ilungele izindawo ezivame ukugqwala.
Insimbi engagqwali 316, ngakolunye uhlangothi, ihamba phambili ekuphikeleni ukugqwala, ikakhulukazi ezindaweni ezine-acidic kanye nezimo zokushisa eziphezulu ezinokumelana nokugqwala okuhle kakhulu, okuvame ukusetshenziswa kumakhemikhali, olwandle kanye nezinye izinhlelo zokusebenza. Ngakho-ke, lapho uthenga izinto zensimbi engagqwali, kubalulekile ukukhetha imodeli efanele ngokuya ngokusetshenziswa okukhethekile kwezindawo ezahlukahlukene.
◉Okwesithathu, umehluko ezicini zemishini
Izakhiwo zemishini yensimbi engagqwali zihlanganisa izinkomba ezifana namandla, i-ductility kanye nobulukhuni. Ngokuvamile, amandla ensimbi engagqwali 201 aphakeme kancane kunalawo ensimbi engagqwali 304, kodwa aphansi kakhulu kunalawo ensimbi engagqwali 316.Insimbi engagqwali 201 kanye ne-304 ine-ductility enhle, kulula ukuyicubungula nokubumba, ifaneleka kwezinye zezinto. ukucubungula izidingo zokusebenza zezikhathi eziphakeme.
Amandla aphezulu ensimbi engagqwali engu-316, kodwa futhi anokumelana okuhle nokugqokwa nokuqina okuqinile, alungele ukumelana namandla aphezulu kanye nendawo yokusebenza yokushisa ephezulu. Ngakho-ke, lapho ukhetha izinto zensimbi engagqwali, udinga ukukhetha okufanele ngokuya ngezidingo ezithile zemishini kanye nokusetshenziswa kwemvelo.
◉Okwesine, umehluko wentengo
Kukhona futhi umehluko phakathi kwentengo yensimbi engagqwali 201, 304 no-316. Ngokuvamile, intengo yensimbi engagqwali 201 iphansi kakhulu, ithengeka kakhulu. Intengo yensimbi engagqwali 304 iphakeme kakhulu, kodwa ngenxa yohlu olubanzi lwezinhlelo zokusebenza nokusebenza okungcono kakhulu sekukonke, kusengenye yezinhlobo ezivame kakhulu zensimbi engagqwali emakethe.
◉ Insimbi engagqwali 316 ibiza kakhulu ngenxa yokumelana nokugqwala okuhle kanye nezakhiwo zemishini, futhi ifaneleka kwezinye izinkambu ezikhethekile ezidinga izakhiwo zezinto ezibonakalayo. Ngakho-ke, lapho uthenga izinto zensimbi engagqwali, udinga ukucabangela izici ezifana nokusebenza kwezinto ezibonakalayo kanye nesabelomali.
Njengomhlinzeki ochwepheshe wezinto zensimbi engagqwali, iShanghai Qinkai Industry Co.
Imboni yasungulwa ngo-2014, futhi ngemva kweminyaka yentuthuko, isibe yinkampani ehlanganisa ukuthengiswa kwamapuleti, amashubhu namaphrofayili.
Ukuhambisana nomgomo wekhasimende kuqala,Qinkaiuzibophezele ekuhlinzekeni amakhasimende ngezinto ezisezingeni eliphezulu zensimbi engagqwali kanye nenkonzo enhle kakhulu!
→ Kuyo yonke imikhiqizo, izinsizakalo kanye nolwazi lwakamuva, sicelaXhumana nathi.
