Electroless nickel plating txheej ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj yog nyias dhau

Qhov saum npoo ntawm qhov chaw uas cov npuas yog adsorbed thiab electroless npib tsib xee plating tov yog cais los ntawm cov npuas, thiab cov electroless nickel plating cov tshuaj tiv thaiv yog thaiv, yog li cov electroless npib tsib xee plating txheej yog nyias. Pockmark tsis xws luag yog feem ntau nyob rau hauv electroplating ntau lawm. Nyob rau hauv tus txheej txheem ntawm kev ua, ib tug loj plating tank yog xaiv thiab compressed cua nplawm, mechanical stirring los yog tsis tu ncua co ntawm cov khoom yog siv los ua zoo do cov khoom, thiab yuav tsis muaj A-hom me ntsis. Nyob rau lub caij ntuj sov, tib neeg lub cev tawm hws ntau, thiab CI nyob rau hauv cov hws stains sab laug rau ntawm qhov chaw ntawm aluminium alloy qhov chaw tom qab raug kov los ntawm tib neeg txhais tes thiab qhov kub thiab av noo ib puag ncig yuav ua rau kom corrosion ntawm aluminium alloys. Yog li ntawd, cov khoom yuav tsum tau muab ntxuav nrog dej deionized tom qab txhua tus txheej txheem los tiv thaiv cov seem ntawm cov kua dej, hws thiab lwm yam khoom uas tuaj yeem ua rau cov khoom tawg yooj yim rau ntawm qhov chaw. Yog tias qhov kev ua haujlwm tsis tuaj yeem npaj tau raws sijhawm thaum lub sijhawm hloov mus rau cov txheej txheem tom ntej, yuav tsum ntsuas kev tiv thaiv xeb.

Lub ntsiab yog vim li cas rau cov tsos ntawm me ntsis ntawm electroplated kub txheej ntawm lub tshuab nqus tsev electroplating hluav taws xob cua sov raj yog raws li nram no:

(1) Kev xaiv tsis tsim nyog ntawm electroless npib tsib xee plating tank thiab txoj kev tsis tsim nyog ntawm mounting thiab dai qhov chaw cuam tshuam rau ib leeg, ua rau muaj kev cuam tshuam tsis zoo hauv cov txheej txheem ntawm cov kua qaub electroless npib tsib xee plating, ua rau hauv chav kawm A mottles ntawm qhov chaw ntawm qhov chaw. .

(2) Thaum Lub Xya Hli-Lub Yim Hli, lub substrate yog qhov yooj yim rau xeb thiab qhov chaw ntawm qhov ua rau B-hom me me. Yog li ntawd, raws li txoj kev sib txawv ntawm mounting thiab dai lub workpiece, cov kev daws teeb meem yog npaj thiab txheeb xyuas los ntawm kev sim.
