I-Phosphating inqubo yokwenza ifilimu yokuguqulwa kwamakhemikhali e-phosphate ngokusebenzisa ukusabela kwamakhemikhali kanye ne-electrochemical, futhi ifilimu yokuguqulwa kwe-phosphate eyakhiwe ibizwa ngokuthi ifilimu ye-phosphating. Inhloso eyinhloko ye-phosphating ukuvikela isisekelo sensimbi nokuvimbela insimbi ukuthi ingagqwali ngezinga elithile; Isetshenziselwa ukucubungula ngaphambi kokudweba ukuze kuthuthukiswe ukunamathela nokumelana nokugqwala kwefilimu kapende; Isetshenziselwa ukunciphisa ukugcotshwa kwefilimu kawoyela ngesikhathi senqubo yokusebenza ebandayo yensimbi.
I-Phosphating iyindlela evame ukusetshenziswa ngaphambi kokwelashwa. Eqinisweni, kufanele kube ekwelashweni kolwelwesi lokuguqulwa kwamakhemikhali. Inqobo nje uma isetshenziswa ku-phosphating yezindawo zensimbi, izinsimbi ezingenayo insimbi njenge-aluminium ne-zinc nazo zingasetshenziswa ku-phosphating. Inqubo yokucwilisa ucwecwe lokusebenza (insimbi, i-aluminium, noma i-zinc) kusixazululo se-phosphating (ezinye izixazululo ezisekelwe kwi-asidi ye-phosphate) nokufaka ungqimba lwefilimu yokuguqula i-crystalline phosphate engancibilikiyo phezulu ibizwa ngokuthi i-phosphating.
Ubumnyama kuyindlela evamile yokwelashwa kokushisa kwensimbi. Umgomo uwukwenza ungqimba lwefilimu ye-oxide endaweni yensimbi ukuze uhlukanise umoya futhi ufeze injongo yokuvimbela ukugqwala. Lapho izidingo zokubukeka ziphezulu, ukwelashwa okumnyama kungasetshenziswa. Ingaphezulu lezingxenye zensimbi liphenduka libe mnyama, ezinye zazo ezibizwa ngokuthi luhlaza okwesibhakabhaka. Ukwelashwa kwe-bluing kuwukwelashwa kwendawo yamakhemikhali. Umsebenzi wayo oyinhloko ukwakha ifilimu ye-oxide eqinile ebusweni bomsebenzi, ukuvimbela ukugqwala nokugqwala, futhi uthuthukise ukumelana nokugqoka komsebenzi. Ukwelashwa okungaphezulu kuphela ngeke kuthinte isakhiwo sangaphakathi. Akukona ukwelashwa ukushisa, kuhluke kakhulu ekucimeni.
Amabhawodi anamandla aphezulu asebenzisa i-phosphating, engagwema nezinkinga ze-hydrogen embrittlement. Ngakho-ke, amabhawodi angaphezu kwebanga le-10.9 emkhakheni wezimboni ngokuvamile asebenzisa ukwelashwa kwendawo ye-phosphating. I-Blackening+oiling iyi-coating edumile yezinsimbi zasezimbonini ngoba ishibhile futhi ibukeka iyinhle ngaphambi kokusetshenziswa kukaphethiloli. Ngenxa yokuba mnyama kwayo, cishe ayinakho ikhono lokuvimbela ukugqwala, ngakho izogqwala ngokushesha ngaphandle kwamafutha.
Ukuze uthole ulwazi olwengeziwe ngezipikili ze-drywall, sicela usithinte.
