Yuav ua li cas kom tsis txhob Electroplating Dipolarization nyob rau hauv hluav taws xob cua sov raj

Thaum cov hlau electrode nthuav tawm ob qho tib si cathodic thiab anodic cov tshuaj tiv thaiv, nws yog hu ua bipolar electrode. Qhov tshwm sim ntawm ib txhij cathodic thiab cathodic cov tshuaj tiv thaiv tshwm sim ntawm ob qhov chaw sib txawv ntawm cov electrode bipolar yog hu ua bipolar phenomenon.

Lub hauv paus ntsiab lus yooj yim yog raws li hauv qab no (noj cov tooj liab plating feem ntau ua piv txwv): nyob rau hauv ib lub xovtooj ntawm electrolytic, tam sim no ntws los ntawm cov hlau (anode tooj liab pob) mus rau electrolyte (plating tov) raws li cov anode, thiab cov tam sim no ntws los ntawm cov hlau. cov electrolyte rau hlau electrode li cathode. Hauv electrochemical txoj kev xav, cov ntsiab lus kev tshaj lij yog thawj hom neeg xyuas pib (xws li hlau) thiab hom thib ob ntawm tus neeg xyuas pib (xws li electrolyte). Yog tias cov hlau A uas tsis txuas nrog lub zog hluav taws xob sab nraud (rectifier) ​​muab tso rau ntawm lub anode thiab cathode hauv electrolytic cell cais cov electrolytic cell mus rau hauv ob lub hlwb, qhov tam sim no ntawm lub anode thiab cathode tsis tuaj yeem ntws los ntawm electrolyte. lub anode mus rau cathode, thiab yuav tsum tau txais qiv los ntawm A. Yog li ntawd, thaum tam sim no ntws los ntawm lub anode mus rau saum npoo ntawm A, cathodic cov tshuaj tiv thaiv tshwm sim rau ntawm qhov chaw (vim qhov kev sib txawv yuam kev - tam sim no ntws mus rau hauv cov hlau los ntawm lub electrolyte), thaum cov tshuaj tiv thaiv anodic tshwm sim ntawm lwm qhov chaw ntawm A (qhov tam sim no ntws mus rau hauv cov electrolyte los ntawm cov hlau). Yog li ntawd, ib sab ntawm Asahi Sun Ncej yog coated nrog hlau, thaum lwm sab ntawm lub cathode yuav yaj hlau A. Lub hauv paus ntsiab lus yog raws li nram no: nyob rau hauv kev xyaum, raws li electrochemical txoj kev xav, ib tug tshwj xeeb anode los yog cathode cov tshuaj tiv thaiv yuav tsum ncav cuag ib tug tej yam. electrode muaj peev xwm (tsis yog voltage) pib cov tshuaj tiv thaiv.

Kev siv tooj liab plating ua piv txwv: Feem ntau, cov kua qaub tooj liab plating yuav raug cov tshuaj tiv thaiv cathodic (tooj liab ions raug txo rau cov hlau) tsuav yog qhov sib txawv ntawm qhov sib txawv ntawm 0.6V. Yog hais tias lub pob tawb titanium nyob rau hauv ib tug ntsug electroplating da dej muaj ib tug tsis kam vim tsis muaj kev sib cuag nrog cov conductive tooj liab bar, yuav muaj qhov sib txawv ntawm lub pob tawb titanium no thiab ob lub titanium blues uas nyob ib sab. Ntev npaum li qhov muaj peev xwm sib txawv no tshaj li qhov muaj nqis, titanium xiav dhau los ua A hauv cov ntawv nyeem dhau los, dhau los ua cov electrode bipolar. Tig lub titanium xiav kev taw qhia ntawm phab ntsa tom ntej, tooj liab yog plated, thaum tig mus rau cathode kev taw qhia tseem yog lub anode.

Kev ntsuas kev teb: Tom qab nkag siab cov ntsiab lus saum toj no, kev daws teeb meem rau qhov teeb meem no yooj yim heev: xyuas kom meej tias tag nrho cov anodes nyob ntawm qhov sib koom ua ke qhov siab txheeb ze rau cathode. Ntawd yog, ib qho kawg yog hauv av, thiab lwm qhov kawg ntsuas cov ntsiab lus ntawm cov anode kom pom tias txhua lub ntsiab lus muaj peev xwm sib koom ua ke. Daim ntawv thov thiab PCB tooj liab electroplating, qhov teeb meem no feem ntau tshwm sim ntawm anode - titanium xiav.

Yog li ntawd, cov kws tshaj lij cov neeg ua haujlwm ntawm Xuguang los ntawm Xuke tau ceeb toom rau koj tias cov kev ntsuas hauv qab no tuaj yeem ua tau:

1. Ntxuav lub conductive tooj liab bar thiab titanium xiav nuv kom paub meej hluav taws xob zoo ntawm titanium xiav thiab conductive tooj liab bar.

2. Ntxiv cov pob tooj liab kom raws sijhawm kom ntseeg tau tias muaj kev sib raug zoo ntawm cov pob tooj liab.

3. Yog hais tias lub fixture ntawm lub cathode tsis nruj nreem clamped thiab ib tug ntawm cov substrates yog tsis raug rau voltage, lub cathode (substrate) ua ib tug bipolar electrode. Hauv qhov no, lub substrate yuav yaj ib nrab.
