Imikhiqizo
Umbala we-chromium zinc water
Zn-228 trivalent chromium color zinc water
Izici
Ukusebenza okuphezulu, ifilimu ewugqinsi, trivalent chromium Plating passivation film.
Umbala obukekayo uhlukile phakathi kwe-chromium eyi-trivalent ukumelana nokugqwala ama-passivators.
Uma sisetshenziswa ngendlela efanele, isikhathi se-NSS singafinyelela ngaphezu kwamahora angu-120 lapho ugqinsi lwe-zinc layer ≧8 micron.
Uhlu olubanzi lobuchwepheshe bokusebenza, kulula ukubunakekela futhi bulawule.
Ingaqhutshwa ukusuka kumazinga okushisa aphansi kuye ezingeni lokushisa elivamile ukuze kuncishiswe izindleko.
Inezinto "zokuziphilisa" ezifana ne-hexavalent chromium.
Ifanelekela i-alkaline cyanide galvanizing kanye ne-acid galvanizing ilenga kanye ne-rolling plating.
operation
Ukulungiswa kwesixazululo se-passivation
Zn-228 trivalent chromium color zinc water 8-10% (volume ratio) standard: 10%
Isikhathi sokungena: 30-90 imizuzwana 45-60 imizuzwana
Izinga lokushisa: 15- 40 ℃ 20-30℃
PH inani: 1.8-3.5 2.2-2.5
Isikhathi sokukhulelwa siyahlukahluka kuye ngokuthi Ukugxilisa ingqondo kwesixazululo se-passivation kanye nempilo yesevisi
Ukugcinwa kwe-add
Titration ngezikhathi ezithile ukuze kugcinwe isisombululo se-passivation sisezingeni elijwayelekile. Uma ukugxila kufanele futhi i-pH iphezulu, lungisa i-pH ngenani elincane elingu-50% HNO3.
Izinyathelo zokuhlaziya
1. Thatha isampula yesixazululo se-passivation engu-10ml bese usifaka ku-flask ye-100ml. Hlanganisa ngamanzi ahlanzekile abe ngu-100ml bese uxuba kahle.
2. Faka ikhambi elihlanjululwe ngenhla kuka-10ml ku-250ml ye-conical flask bese uyihlanza ibe ngu-100ml ngamanzi ahlanzekile.
3. Engeza u-5ml 20% NaOH no-1ml 35% H2O2.
4. Bilisa ikhambi cishe imizuzu emi-5.
5. Engeza isixazululo esingu-1ml esingu-10% se-NiCl2 bese uqhubeka ubila cishe imizuzu emi-2.
6. Pholisa ikhambi lokushisa kwegumbi.
7. Engeza i-HCl egxilile engu-10ml, i-1g NH4F, i-10ml engu-10% yesisombululo se-potassium iodide kanye nenkomba yesitashi engu-2ml ngenkathi uhlanganisa.
8. Titrate isixazululo ukusula/umbala oluhlaza 0.1NNa2S2O3.

Ukungcola kwensimbi
Ukungcola kwensimbi kuthinta bonke ukusebenza okuphezulu kwe-trivalent chromium passivation technologies. I-ayoni ingabangela ifilimu ye-passivation ibe phuzi, ingcolile, iphele, futhi inciphise ukuvikeleka. Ithangi lokucubungula lihlanzwa kanye noma kabili ngokushintsha amahora ayisishiyagalombili ukuvimbela ukuhlakazeka kwezingxenye eziwayo. Kufanele iqinisekise ukugeza kwamanzi okwanele. Uketshezi olugelezayo ngaphambi kokudlula kufanele lulahlwe kaningi futhi kushintshwe ukuze kuncishiswe i-ayoni.
Izingxenye zamashubhu kufanele zithululwe eshubhuni ngaphambi kokungena kwisisombululo sokudlula.
prompt
1. Kunconywa ukucwilisa ngaphambili isixazululo se-passivation nge-HNO3, ikakhulukazi uma i-alkaline icwebezela, ukuze kunwetshwe impilo yesevisi yesixazululo sokudlulisa.
2. Inani le-pH lesixazululo se-Zn-228 passivation lingalungiswa nge-lye ewuketshezi futhi lihlambulule i-HNO3.
