Chemical nickel phosphorus plating ntawm stainless hlau

Chemical nickel phosphorus plating ntawm stainless hlau

XMLS-NST 603 hlau-raws li tshuaj nickel plating tshem tawm yog ib yam khoom zoo, uas tsis yog tsuas yog haum rau electroplating npib tsib xee txheej ntawm hlau substrates, tab sis kuj rau kev tshem tawm cov tshuaj nickel coatings ntawm hlau substrates. Lub ntsiab kom zoo dua yog tias nws yog ib puag ncig tus phooj ywg thiab tsis suav nrog; Cov tshuaj yog ruaj khov thiab tuaj yeem ua haujlwm tsis tu ncua; Cov tshuaj tsis corrode lub substrate thiab muaj lub neej ntev.

1. Ntxiv 2/3 dej rau lub plating da dej thiab yaj tag nrog 50g/L NaOH.

2. Ntxiv qhov xav tau ntawm XMLS-NST 603 A (75g / L) thiab do kom huv si kom yaj.

3. Ntxiv qhov xav tau ntawm XMLS-NST 603 B (200ml / L) thiab do sib npaug.

4. Ntxiv dej rau qhov ntim tau teev tseg thiab ua kom sov rau qhov ua haujlwm kub (80-90 degree ).

Dab tsi yog qhov kev kho deg ntawm electroless nickel plating

1. Kev tshem tawm xeb: Muaj cov txheej txheem siv tshuab, tshuaj, thiab electrochemical rau kev tshem tawm xeb. Kev tshem tawm cov tshuab xeb yog kev kho tshuab uas muaj cov xuab zeb blasting, sib tsoo, dov, lossis polishing saum npoo ntawm cov khoom ua haujlwm kom ua tiav qib thaum tshem tawm cov xeb txheej. Kev tshem tawm cov tshuaj xeb yog cov txheej txheem ntawm kev siv cov kua qaub los yog alkaline kom muaj zog corrode hlau cov khoom, tshem tawm cov xeb txheej ntawm cov khoom los ntawm kev siv tshuaj thiab cov neeg kho tshuab tev cov nyhuv ntawm hydrogen npuas tsim thaum lub sij hawm etching txheej txheem.

2. Kev ua kom muaj zog: Kev ua kom muaj zog yog cov txheej txheem kom tau txais qhov chaw ua kom tag nrho rau ib feem, thiab cov kua qaub uas siv rau hom etching no txawv rau cov khoom sib txawv.

3. Kev tshem tawm roj: cov txheej txheem tshem tawm cov roj tuaj yeem muab faib ua cov kuab tshuaj organic thiab tshem tawm cov roj tshuaj lom neeg. Cov yam ntxwv ntawm cov kuab tshuaj organic rau kev tshem tawm cov roj yog cov roj tshem tawm ceev ceev, tsis muaj corrosion ntawm cov hlau, thiab xav tau cov tshuaj los yog electrochemical txoj kev los ntxiv cov roj tshem tawm. Cov organic solvents xws li roj av, kerosene, benzene, ketones, qee yam chlorinated alkanes, thiab olefins. Lwm qhov zoo ntawm cov organic hnyav degreasing yog tias cov kuab tshuaj tom qab degreasing tuaj yeem rov ua dua thiab rov siv dua. Organic kuab tshuaj feem ntau yog flammable thiab yuav tsum tau siv nrog ceev faj ntxiv.

Cov tshuaj nickel plating nto kho rau cov roj tshem tawm siv cov nyhuv saponification ntawm alkaline cov kev daws teeb meem thiab cov nyhuv emulsification ntawm cov tshuaj nquag ntawm cov roj uas tsis yog saponified kom tshem tawm ntau cov roj stains ntawm qhov chaw ua haujlwm. Qhov ntsuas kub rau kev tshem tawm cov roj tshuaj feem ntau yog nruab nrab ntawm 60-80 degrees, thiab cov roj tshem tawm cov txiaj ntsig ntawm cov khoom ua haujlwm feem ntau pom, qhia tias qhov chaw ntawm lub workpiece tuaj yeem ntub dej los ntawm dej, uas yog ib qho cim ntawm cov roj ua tiav. tshem tawm
