Taw qhia txog cov teeb meem tseem ceeb ntawm Electroless Nickel Plating ntawm Hluav Taws Kub Kub Tubes

Vim nws qhov zoo ntawm qhov sib xws, hardness, hnav tsis kam, thiab corrosion kuj, nrog rau nws cov khoom siv lub cev thiab tshuaj lom neeg, electroless nickel txheej muaj ntau yam kev siv. Nrog rau kev txhim kho tas mus li thiab kev hloov pauv ntawm cov kev lag luam muaj feem xyuam, tshuaj lom neeg nickel plating tshuab kuj tseem hloov mus tas li kom tau raws li qhov xav tau ntau dua thiab xav tau kev siv. Tib lub sijhawm, thev naus laus zis yuav tsum tau txhim kho thiab cov teeb meem yuav tsum tau daws. Ntawm no yog yuav ua li cas los daws cov teeb meem tshwm sim hauv chemical nickel plating. Cia peb saib ua ke nrog Changzhou Stainless Steel Chemical Nickel Factory.

1. Pitting thiab pinholes hauv txheej.

Qhov saum npoo ntawm cov khoom plated yog qhov tsis zoo. Yog tias cov khoom tsis huv, cov nplai oxide, thiab lwm yam tsis raug tshem tawm tag nrho, pH tus nqi ntawm cov tshuaj plating thiab qhov tsis ruaj khov ntawm cov tshuaj plating yuav ua rau pitting thiab pinholes hauv txheej. Qhov saum npoo roughness ntawm cov khoom yuav tsum tau txo kom ntau li ntau tau. Qhov ci ntsa iab ntawm qhov chaw yooj yim, qhov ci dua cov tshuaj nickel txheej, thiab tsawg dua pinholes hauv txheej. (Ceeb toom: Tsis txhob kho tus nqi pH ntawm cov tshuaj plating thaum lub sij hawm plating, cov tshuaj plating yuav tsum tau ncig thiab lim, qhov tsim nyog ntawm stabilizer kuj tuaj yeem ntxiv. los yog ntawm 90 degree rau kab rov tav kom ntau li ntau tau.)

2. Tsis sib xws txheej thickness.

Vim muaj qhov sib txawv ntawm qhov chaw ntawm qhov chaw thiab lub dav hlau kab rov tav, tus nqi ntawm cov pa tawm hydrogen sib txawv thaum lub sij hawm tshuaj nickel plating. Cov roj hydrogen tsim tawm ntawm qhov tuaj yeem tawm sai sai, thaum cov roj hydrogen tsim tawm ntawm qhov chaw qis qis yuav tsum tau nce raws li qhov chaw mus rau ntug ua ntej tawm mus, yog li txo qis lub sijhawm sib cuag ntawm qhov chaw thiab cov tshuaj plating, ua rau cov txheej txheem tsis sib xws. tuab. (Faj seeb: Thaum qhov saum npoo ntawm ib feem yog kwv yees li ntawm lub dav hlau kab rov tav, qhov nce ntawm cov pa roj hydrogen nyob rau saum npoo ntawm ib feem kuj tuaj yeem ua rau cov txheej txheej sab saud me ntsis thinner dua li qhov qis dua.) Tsis tas li ntawd, hauv txhua qhov chaw. uas cuam tshuam qhov kev tso tawm ntawm cov roj hydrogen, nws muaj peev xwm ua rau cov txheej txheem nyias thiab qhov chaw kom muaj pinholes ntau dua. Rau qhov loj-loj, nws raug nquahu kom siv txoj kev nce thiab nqis viav vias kom ntau li ntau tau thaum lub sijhawm plating, thiab siv cov txheej txheem plating hauv lub xeev ntws los pab txhawb kev tawm ntawm cov pa roj hydrogen.

3. Qhov chaw ntawm cov txheej txheej.

Tom qab ntau qhov kev coj ua thiab kev tshuaj xyuas, nws tau pom tias qhov tshwm sim ntawm qhov chaw ntawm cov txheej txheej tsis cuam tshuam nrog cov dej deionized ntawm cov tshuaj plating, tab sis theej rau adhesion ntawm qee cov organic "impurities" ntawm qhov chaw. plating daim, uas tsis tuaj yeem ntxuav kom huv si, yog li hloov kev tsim thiab kev loj hlob tus cwj pwm ntawm Ni-P alloy txheej ntawm qhov chaw, tsim qhov tsis sib xws "qhov chaw". Tom qab ntawd, cov khoom siv sib txawv tau siv los ntxiv dag zog rau kev ntxuav ua ntej plating, tshem tawm qhov tshwm sim ntawm "spots" ntawm txheej txheej thiab rov ua kom zoo li qub thiab ci ntsa iab.
