Umgomo wokugqwala kwezinzipho zensimbi:
Ukugqwala kuwukusabela kwamakhemikhali, lapho insimbi ishiywe isikhathi eside izogqwala.I-iron igqwala kalula, hhayi nje ngenxa yemvelo yayo yamakhemikhali asebenzayo, kodwa nangenxa yezimo zangaphandle.Umswakama ungenye yezinto ezenza ukugqwala kwensimbi kalula.
Nokho, amanzi kuphela angenzi nokugqwala kwensimbi.Kuphela lapho umoya-mpilo osemoyeni uncibilika emanzini, umoya-mpilo uhlangana nensimbi endaweni ezungezile ngamanzi ukuze ukhiqize okuthile okuyi-iron oxide, okuwukugqwala.
Ukugqwala kuyinto ebomvu ngokunsundu futhi ayiqinile njengensimbi futhi ingachitheka kalula.Lapho ucezu lwensimbi lugqwalile ngokuphelele, umthamo ungakhula izikhathi eziyi-8.Uma ukugqwala kungasuswa, ukugqwala okuyiziponji kuthambekele kakhulu ekumunceni umswakama, futhi insimbi izogqwala ngokushesha.I-ayoni izoba nzima kakhulu lapho igqwala, cishe izikhathi ezi-3 kuya kwezi-5 isisindo sayo sokuqala.
Iron izinzipho zivame kakhulu ekuphileni kwethu kwansuku zonke izinzipho, liphinde ububanzi ebanzi kakhulu kwezicelo, kodwa iron izinzipho babe kusimo kulula ukugqwala, ngizokutshela ukuthi yiziphi izindlela ukuvimbela ukugqwala yensimbi izinzipho.
Ukuvimbela izinzipho ukuthi zingagqwali kungaba izindlela ezilandelayo:
1, ukwakheka kwe-alloy ukushintsha isakhiwo sangaphakathi sensimbi.Isibonelo, i-chromium, i-nickel nezinye izinsimbi ezengezwe ensimbi evamile eyenziwe ngensimbi engagqwali, kwandisa kakhulu ukumelana nokugqwala kwemikhiqizo yensimbi.
2,Ukumboza ubuso bemikhiqizo yensimbi ngesendlalelo sokuzivikela kuyindlela evamile futhi ebalulekile yokuvimbela imikhiqizo yensimbi ekugqwaleni.Ngokuya ngokwakhiwa kwesendlalelo sokuzivikela, singahlukaniswa ngezigaba ezilandelayo:
a.Ukugqoka ubuso bemikhiqizo yensimbi ngamafutha amaminerali, upende noma ukudubula koqweqwe lwawo, ukufafaza ipulasitiki, njll. Isibonelo: izinqola, amabhakede, njll zivame ukudweba, futhi imishini ivame ukugcotshwa ngamafutha amaminerali, njll.
b.Ukufakwa phezu kwensimbi nensimbi nge-electroplating, ukushisa okushisayo nezinye izindlela, njenge-zinc, ithini, i-chromium, i-nickel nokunye, ungqimba lwensimbi engangeni nokugqwala.Lezi zinsimbi zingakha ifilimu eliminyene le-oxide ngaphezulu, ngaleyo ndlela ivimbele imikhiqizo yensimbi ukuthi ingagqwali lapho ihlangana namanzi, umoya nezinye izinto.
c.Ngamakhemikhali yenza ingaphezulu lemikhiqizo yensimbi likhiqize ungqimba lwefilimu ye-oxide eminyene futhi ezinzile ukuvikela imikhiqizo yensimbi ukuthi ingagqwali.
3,Ukugcina ingaphezulu lemikhiqizo yensimbi ihlanzekile futhi yomile futhi kuyindlela enhle yokuvimbela imikhiqizo yensimbi ukuthi ingagqwali.
