Kuthunyelwe ku 2015-11-16Ngocwaningo olwengeziwe, abantu bayaqaphela ukuthi ubuchwepheshe be-dacromet abuyona ubuchwepheshe obuluhlaza ngokuphelele futhi obungenawo ukungcola, kunezinye izithiyo.
1. Inkinga yokungcola: Isixazululo se-Dacromet sokuqukethwe kwe-chromic acid siphezulu kakhulu, ekulungiseni nasekusetshenzisweni kwabantu nakanjani bazohlangana nakho, ukusebenzisa iziqukathi kanye nemishini kuzongcoliswa nakanjani, kufakwe ifilimu ekuqaleni kwesikhathi. inqubo, izoba ngokuhwamuka komhwamuko wamanzi (kusuka kulwazi lwe-chromium plating kuya), ngakho-ke ukulungiswa kusuka kwisixazululo ukukhiqiza inqubo yokuhlanganisa ukuze kungabikho kukhishwa kwegesi, uketshezi kanye nezinto eziyingozi eziqinile kunzima kakhulu, noma ukutshalwa kwezimali kwemishini yokuvikela imvelo kukhulu kakhulu. .Futhi, lapho ukugqwala kwe-coating sekuphinde kube nomonakalo we-Dacromet, ama-chromium ayisithupha efilimu yokumboza azokhipha.I-chromium ene-hexavalent ebusheni bomuntu kanye ne-carcinogenicity inamandla kakhulu, okwamanje amazwe amaningi e-chromium ene-hexavalent anomkhawulo wezindinganiso eziqinile futhi ayakwenqabela nokusetshenziswa.Ngakho-ke, isibe isithiyo esingenakunqotshwa ku-Dacromet.
2.Izinga lokushisa eliphezulu le-sintering, ukusetshenziswa kwamandla okukhudlwana.
3.Ukuqina kobuso nokumelana nokugqokwa akukuhle, kusenezinkinga zokugqwala kwe-galvanic kanye nezinsimbi ezingafani, ezithinta ikhwalithi yendawo yomkhiqizo nokusebenza kokuqeda ukugqwala.
