Kuthunyelwe ku 2018-05-07Ngokuthuthuka okusheshayo kobuchwepheshe besimanje bokukhiqiza, imikhiqizo eminingi yobuchwepheshe obuphezulu iye yasetshenziswa.Ubuchwepheshe bokucubungula kuletha lula kakhulu empilweni yethu.I-Dacromet kufanele iqondwe ngabantu abaningi.
I-Dacromet inezicelo ezimbonini eziningi.Ubuchwepheshe be-Dacromet manje buhlanganiswe nezingubo eziningi.Ingadlala umphumela omuhle kakhulu wokulwa nokugqwala ebusweni bomkhiqizo.Ngakho Kungani ikwazi ukulondoloza ukwaziswa?
I-Dacromet coating, ukubukeka kuyi-matt silver-gray, eyakhiwe ngeshidi lensimbi elihle kakhulu zinc, i-aluminium kanye nezakhi zechromate.Ngemuva kokuthi i-workpiece yehlisiwe futhi idutshulwe yaqhunyiswa, i-Dacromet yagcotshwa.
I-Dacromet liquid iwuhlobo loketshezi lokwelapha olusekelwe emanzini.Izingxenye zensimbi ziyagcotshwa noma zifafazwe esixazululweni sokwelapha esisekelwe emanzini, bese ziqiniswa esithandweni futhi zibhakwe cishe ku-300 ° C. ukuze zenze i-inorganic coating ye-zinc, i-aluminium ne-chromium.Lapho welashwa, umswakama wefilimu yokumboza, i-organic (cellulose) nezinye izakhi eziguquguqukayo ziyashintshashintsha, kanye nempahla ye-oxidizing ye-high-valent chromium kasawoti otshwaleni kamama we-Dacromet yenza amandla e-electrode abe nenani elikhulu elibi.
Ngemuva kwe-aluminium foil slurry kanye ne-iron matrix, inhlanganisela kasawoti ye-chromium ye-Fe, i-Zn, ne-Al iyakhiwa.Ngenxa yokuthi ungqimba lwefilimu lutholakala ngokuqondile ngemva kwe-substrate, ungqimba olulwa nokugqwala luminyene kakhulu.Ngaphansi kwendawo egqwalayo, ukumbozwa kuzokwakha amabhethri amaningi ayisisekelo, okungukuthi, usawoti omubi kakhulu we-Al ne-Zn uzoqoshwa kuqala kuze kube yilapho ekwazi ukugqwala i-substrate ngokwayo ngemva kokuba idliwe.
