Dej Txias Pulse Periodic Reverse 415V Electrolysis Fais Fab

1. Lub hauv paus ntsiab lus ntawm periodic rov qab mem tes plating

Hauv cov txheej txheem pulse plating, thaum tam sim no qhib, electrochemical polarization nce, cov hlau ions nyob ze ntawm thaj chaw cathode tau muab tso rau tag nrho, thiab txheej txheej plating yog finely crystallized thiab ci; Thaum qhov tam sim no raug muab tua, qhov tso tawm ions nyob ze ntawm thaj chaw cathode rov qab mus rau qhov pib concentration. Cov concentration polarization raug tshem tawm.
Periodic commutation mem tes plating feem ntau hu ua ob (ie bidirectional) mem tes plating. Nws qhia txog cov txheej txheem rov qab pulse tam sim no tom qab tso tawm ib txheej ntawm pem hauv ntej mem tes tam sim no. Lub sijhawm pulse pem hauv ntej yog ntev thiab lub sijhawm rov qab mem tes yog luv. Qhov tsis sib xws ntawm cov anode tam sim no faib tawm los ntawm lub sijhawm luv luv rov qab mem tes yuav ua rau lub ntsej muag ntawm cov txheej txheem kom yaj thiab flattened. Cov kev hloov pauv hloov pauv ntawm cov mem tes waveform yog qhia hauv qab no.

Nta
Siv lub sijhawm tswj kev ua haujlwm, qhov teeb tsa yooj yim thiab yooj yim, thiab lub sijhawm ua haujlwm ntawm qhov zoo thiab qhov tsis zoo tam sim no polarity tuaj yeem raug teeb tsa raws li cov txheej txheem plating.
Nws muaj peb lub xeev ua haujlwm ntawm kev hloov pauv tsis siv neeg, zoo thiab tsis zoo, thiab thim rov qab, thiab tuaj yeem hloov pauv qhov polarity ntawm cov zis tam sim no.

Lub superiority ntawm periodic commutation mem tes plating
1 Rov qab pulse tam sim no txhim kho cov thickness faib ntawm txheej, lub thickness ntawm txheej yog uniform, thiab lub leveling yog zoo.
2 Lub anode dissolution ntawm lub rov qab mem tes ua rau cov concentration ntawm cov hlau ions ntawm lub cathode nto sai sai, uas yog conducive rau siv ib tug siab pulse tam sim no ceev nyob rau hauv lub tom ntej no cathode voj voog, thiab lub siab pulse tam sim no ceev ua rau cov tsim ceev ntawm. siv lead ua nucleus sai dua qhov kev loj hlob ntawm cov siv lead ua, yog li Cov txheej yog ntom thiab ci, nrog tsawg porosity.
3. Qhov thim rov qab pulse anode stripping zoo heev txo cov adhesion ntawm cov organic impurities (xws li brightener) nyob rau hauv txheej, yog li cov txheej muaj purity siab thiab muaj zog tiv thaiv kom tsis muaj xim, uas yog tshwj xeeb tshaj yog nyob rau hauv silver cyanide plating.
4. Qhov rov qab mem tes tam sim no oxidizes hydrogen uas muaj nyob rau hauv txheej, uas tuaj yeem tshem tawm hydrogen embrittlement (xws li cov mem tes rov qab tuaj yeem tshem tawm cov co-deposited hydrogen thaum lub sij hawm electrodeposition ntawm palladium) los yog txo cov kev ntxhov siab sab hauv.
5. Lub sij hawm rov qab cov mem tes tam sim no khaws cov npoo ntawm cov plated nyob rau hauv lub xeev nquag txhua lub sijhawm, kom cov txheej txheej plating nrog kev sib txuas zoo tuaj yeem tau txais.
6. Rov qab mem tes yuav pab tau kom txo tau qhov tseeb thickness ntawm diffusion txheej thiab txhim kho cov cathode tam sim no efficiency. Yog li ntawd, cov pulse tsis zoo yuav ua rau kom tus nqi deposition ntawm txheej.
7 Nyob rau hauv lub plating system uas tsis tso cai los yog ib tug me me ntawm additives, ob chav mem tes plating yuav tau ib tug zoo, du, thiab du txheej.
Raws li qhov tshwm sim, cov txheej txheem kev ua tau zoo xws li kub tsis kam, hnav tsis kam, vuam, toughness, corrosion kuj, conductivity, tsis kam rau discoloration, thiab smoothness tau nce exponentially, thiab nws tuaj yeem txuag tau cov hlau tsis tshua muaj nqi (txog 20% ​​-50). %) thiab txuag cov additives (xws li Bright silver cyanide plating yog li 50% -80%)
