Lapho i-workpiece idinga isikhathi eside sokugcina nokuhamba, kulula ukukhiqiza ukugqwala, futhi umkhiqizo wokugqwala uvame ukugqwala okumhlophe.I-workpiece kufanele idluliswe, futhi indlela evamile yokudlula i-chromium-free passivation.
Ngakho-ke iyini inzuzo yokuvikelwa kwemvelo yensimbi engagqwali (i-chromium-free) isixazululo se-passivation phezu kwamafutha okuvimbela ukugqwala?Amafutha e-Anti-rust ukusetshenziswa kwefilimu yamafutha ukuvala ama-pores endaweni yensimbi ukuze ahlukanise ukuxhumana nomoya-mpilo futhi avimbele ngokuphumelelayo ukugqwala, empeleni, akukho ukusabela.Ifilimu kawoyela kulula ukususwa futhi ichithwe nenqubekelaphambili yokukhiqiza.
I-passivation engenayo i-chromium iwukusetshenziswa kwezinto ezine-oxidizing esixazululweni se-passivation ukukhiqiza ukusabela kwe-REDOX ngensimbi, futhi umphumela uwukukhiqiza ukusebenza okuncane kakhulu, okuminyene, okuhle kokumboza, futhi kukhangiswe ngokuqinile endaweni yensimbi yefilimu ye-passivation. .
Le nqubo iwukusabela kwamakhemikhali.
Ngakho ngesikhathi esifanayo, ake futhi siqonde izinzuzoinsimbi engagqwali ukuvikelwa kwemvelo(i-chromium-free) isixazululo se-passivation?
1. Uma kuqhathaniswa nendlela yendabuko yokubeka uphawu ngokomzimba, ukwelashwa kwe-chromium-free passivation kunezici zokungakhulisi ukushuba kwesiqeshana sokusebenza nokushintsha umbala, ukuthuthukisa ukunemba kanye nenani elingeziwe lomkhiqizo, okwenza umsebenzi ube lula.
2. I-Chromium-free passivation ikhuthaza ukwakheka kwefilimu ye-oksijini yesakhiwo samangqamuzana endaweni yensimbi, ungqimba lwefilimu luminyene, lusebenza kahle, futhi lusemoyeni, ngakho-ke, uma kuqhathaniswa nendlela yendabuko yokumboza uwoyela ophikisana nokugqwala, i-passivation. ifilimu elakhiwe i-passivation engenayo i-chromium izinzile futhi imelana nokugqwala.
Iqembu le-EST Chemical Groupibilokhu inamathela "enhliziyweni yokuhlinzeka amakhasimende ngemikhiqizo nezinsizakalo ezincintisanayo ukuze kuzuze umphakathi wesintu" inkolelo yemishini, ukuqamba okusha okuqhubekayo, ukuze amakhasimende axazulule izinkinga emkhakheni wokuvimbela ukugqwala kwe-passivation, ukuhlinzeka ngemikhiqizo yobuchwepheshe bekhwalithi ephezulu, futhi ngokwezidingo zamakhasimende ukunikeza isethi egcwele yezixazululo ukuhlangabezana nezidingo ezikhethekile zamakhasimende.Sizinikezele ekuhlinzekeni isevisi yekhwalithi nekhwalithi yawo wonke amakhasimende, futhi sibheke phambili ekusebenzeni nawe ukuze siwine!
