Indlela esivimba ngayo ukugqwala ku-gardenrail yensimbi enwetshiwe imi kanje:
1. Shintsha isakhiwo sangaphakathi sensimbi
Isibonelo, ukukhiqiza ama-alloy ahlukahlukene amelana nokugqwala, njengokwengeza i-chromium, i-nickel, njll. kunsimbi evamile ukwenza insimbi engagqwali.
2. Indlela yesendlalelo esivikelayo
Ukumboza ingaphezulu lensimbi ngongqimba oluyisivikelo kuhlukanisa umkhiqizo wensimbi endaweni egqwalile ezungezile ukuvikela ukugqwala.
(1). Gcoba ingaphezulu lemeshi yensimbi enwetshiwe ngowoyela wenjini, i-petroleum jelly, upende noma uyimboze ngezinto ezingezona ezensimbi ezimelana nokugqwala njengoqweqwe lwawo kanye nepulasitiki.
(2). Sebenzisa i-electroplating, i-hot plating, i-spray plating nezinye izindlela ukuze ugcobe ingaphezulu lepuleti lensimbi ngongqimba lwensimbi olungagqwali kalula, njenge-zinc, ithini, i-chromium, i-nickel, njll. Lezi zinsimbi zivame ukwenza ifilimu ye-oxide eminyene ngenxa ye-oxidation, ngaleyo ndlela ivimbele amanzi nomoya ensimbi egqwalile.
(3). Sebenzisa izindlela zamakhemikhali ukuze wakhe ifilimu ye-oxide enhle futhi ezinzile endaweni yensimbi. Isibonelo, ifilimu ye-ferric oxide emnyama enhle yenziwa ebusweni bepuleti lensimbi.
3. Indlela yokuvikela i-Electrochemical
Indlela yokuvikela i-electrochemical isebenzisa umgomo wamaseli e-galvanic ukuvikela izinsimbi futhi izama ukuqeda ukusabela kwe-galvanic cell okubangela ukugqwala kwe-galvanic. Izindlela zokuvikela i-electrochemical zihlukaniswe izigaba ezimbili: ukuvikelwa kwe-anode nokuvikelwa kwe-cathodic. Indlela esetshenziswa kakhulu ukuvikela i-cathodic.
4. Phatha abezindaba ezonakalisayo
Susa imidiya egqwalayo, njengokusula njalo okokusebenza kwensimbi, ukubeka ama-desiccants kumathuluzi anembayo, kanye nokwengeza inani elincane le-corrosion inhibitors elingabambezela izinga lokugqwala kumidiya egqwalayo.
5. Ukuvikelwa kwe-electrochemical
1. Indlela yokuvikela i-anode yomhlatshelo: Le ndlela ixhuma insimbi esebenzayo (njenge-zinc noma i-zinc alloy) nensimbi ukuze ivikelwe. Lapho ukugqwala kwe-galvanic kwenzeka, le nsimbi esebenzayo isebenza njenge-electrode engalungile ukuze ibhekane ne-oxidation reaction, ngaleyo ndlela yehlise noma ivimbele Ukugqwala kwensimbi evikelwe. Le ndlela ivame ukusetshenziselwa ukuvikela izinqwaba zensimbi namagobolondo emikhumbi ehamba olwandle emanzini, njengokuvikelwa kwamasango ensimbi emanzini. Izingcezu eziningana ze-zinc zivame ukushiselwa ngaphansi komugqa wamanzi wegobolondo lomkhumbi noma ku-rudder eduze kwe-propeller ukuvimbela i-hull, njll. ukugqwala.
2. Indlela yokuvikela yamanje ehlabeke umxhwele: Xhuma insimbi ukuze ivikelwe esigxotsheni esinegethivu sikagesi, bese ukhetha olunye ucezu lwento engenayo ye-conductive ukuze uxhume esigxotsheni esihle sokuphakelwa kwamandla. Ngemva kokunika amandla, ukunqwabelana kwamacala amabi (ama-electron) kwenzeka endaweni yensimbi, ngaleyo ndlela kuvimbela insimbi ekulahlekelweni kwama-electron futhi kufezwe injongo yokuvikela. Le ndlela isetshenziswa kakhulu ukuvimbela ukugqwala kwezinto zensimbi enhlabathini, emanzini olwandle namanzi omfula. Enye indlela yokuvikela i-electrochemical ibizwa ngokuthi ukuvikelwa kwe-anode, okuyinqubo lapho i-anode idlula phakathi kwebanga elithile elinamandla ngokusebenzisa i-voltage yangaphandle. Ingavimba ngokuphumelelayo noma ivimbele imishini yensimbi ekugqwaliseni ama-asidi, ama-alkali nosawoti.
