Lapho uthengaingxube ye-magnesiumizinto zokwakha noma ukulungisa iqoqo lemikhiqizo ye-magnesium alloy, uma udinga ukuyigcina, kunconywa ukwenza umsebenzi omuhle wokwelapha okulwa nokugqwala ezintweni kanye nemikhiqizo ukuvimbela i-oxidation futhi kuthinte ukusetshenziswa kamuva.
Ukuze uvimbele okokusebenza kwe-magnesium ekungcoleni noma ukugqwala ngesikhathi sokuthutha nokugcinwa, imikhiqizo ehlanzwe phezulu futhi yaphumelela ekuhlolweni kufanele igcotshwe ngamafutha futhi ipakishwe kungakapheli amahora angama-48. Ngaphambi kokusebenzisa izinto ze-magnesium alloy, ungqimba oluvikelayo lwamafutha e-anti-rust kufanele lususwe, ngakho-ke amafutha e-anti-rust ayadingeka ukuze abe nezindawo ezinhle kakhulu zokulwa nokugqwala, ukukhulula kalula nokukhipha amafutha. Ngakho-ke, ungqimba oluncane lwamafutha alwa nokugqwala ngokuvamile lusetshenziswa. Izinto ezihlukahlukene ezivimbela ukugqwala ezifana ne-oxidized wax paste, ama-sulfonate ancibilikayo emanzini, ama-fatty acids, ama-ester, insipho, njll. kwengezwa emafutheni amaminerali, avame ukusetshenziswa njengamafutha aphikisana nokugqwala we-magnesium alloys. Into evimbela ukugqwala yakha ifilimu ye-polymer evimbela ukugqwala kwe-hydrophobic endaweni yokuthinta kawoyela nensimbi, edlala indima yokuvikela.
I-Magnesium alloys iyakwazi ukugqwala ngaphansi kwezimo zemvelo. Ngaphezu kwendlela yokusebenzisa uwoyela wokugqwala, amaphuzu alandelayo kufanele anakwe ngesikhathi sokusetshenziswa, ukugcinwa nokugcinwa:
1. Ama-alloys e-Magnesium akufanele avezwe emoyeni onomswakama isikhathi eside, futhi imvula nenkungu kuvinjelwe ngokuqinile;
2. Lapho ugcina ama-alloys e-magnesium, kwenqatshelwe ngokuphelele ukuthintana ngokuqondile nama-acids, ama-alkali nosawoti;
3. Umswakama wendawo yokugcina impahla ye-magnesium akufanele udlule i-75%, futhi izinga lokushisa akufanele lishintshe kakhulu;
4. Ngesikhathi sokuthutha, ingaphezulu le-magnesium alloy kumele livalwe futhi limbozwe ukuvimbela umswakama. Uma kutholakala ukugqwala okuncane, kufanele kukhululwe ngokushesha, kuhlanjululwe, kuhlanzwe emikhiqizweni yokugqwala futhi yomiswe, bese ivalwa ngamafutha futhi;
5. Uma ingxube ye-magnesium igcinwa isikhathi eside, kufanele ihlolwe njalo futhi ukwelashwa okudingekayo kwe-anti-corrosion kufanele kwenziwe.
