Tsim cov kev cai rau dai fixtures nrog cov txheej txheem

Lub luag haujlwm ntawm electroplating dai cov cuab yeej yog dai lossis kho ntau qhov chaw, ua rau lawv txuas nrog cathode. Thaum lub sij hawm anodizing thiab electropolishing, lawv txuas nrog lub anode, ua tam sim no rau cov khoom, thiab yog li ua tiav lub hom phiaj ntawm kev tsim cov txheej los yog lwm yam kev kho mob. Hangers yog qhov tseem ceeb hauv kev txhim kho cov khoom zoo, txo cov nqi tsim khoom, txo kev siv zog, thiab ua kom muaj kev nyab xeeb.
Tsim cov kev cai rau kev siv cov cuab yeej dai rau tooj liab thiab npib tsib xee plating
Tam sim no, tooj liab thiab npib tsib xee plating feem ntau yog siv los ua cov txheej nruab nrab rau cov hniav electroplating, siv cov txheej txheem ci electroplating. Thaum lub sij hawm electroplating txheej txheem, lub cathode yuav tsum tau txav los yog ncig los lim cov tshuaj plating, thiaj li yuav tau txais ib daim iav ci txheej. Yog li ntawd, cov kev xav tau ntau dua yog xav tau rau cov cuab yeej dai, uas yuav tsum tau ua raws li cov hauv qab no:
(1) Cov khoom siv hluav taws xob yuav tsum tau ua los ntawm cov tooj liab ntshiab nrog cov khoom siv zoo.
(2) Qhov chaw sib cuag ntawm lub rooj sib dhos thiab cov khoom ua haujlwm yuav tsum me me li sai tau kom tsis txhob muaj qhov tshwm sim ntawm cov txheej txheem tsis zoo ntawm kev sib cuag ntawm cov khoom siv thiab cov khoom ua haujlwm vim yog lub zog rub.
(3) Nws yog qhov zoo tshaj plaws los siv elastic bonding ntawm lub cuab yeej dai thiab lub workpiece los tiv thaiv lub workpiece los ntawm kev cuam tshuam conductivity vim tsis muaj zog bonding thaum lub sij hawm cathode txav los yog circulating pom ntawm lub plating tov.
(4) Qhov chaw ntawm lub fixture uas tsis tuaj rau hauv kev sib cuag nrog lub workpiece yuav tsum tau insulated, thiab cov rwb thaiv tsev yuav tsum tau zoo thiab muaj ib tug tej thickness ntawm rwb thaiv tsev txheej. Qhov no tuaj yeem tiv thaiv qhov tsis zoo ntawm cov txheej txheem rwb thaiv tsev los ntawm kev ua kom muaj zog ntau dhau vim yog tam sim no, uas yuav ua rau cov noob, nodules, lossis txawm tias paj thaum lub sij hawm electroplating txheej txheem, cuam tshuam rau electroplating zoo thiab txo cov kev ua tau zoo ntawm cov txheej txheem plating.
Cov qauv tsim rau cov khoom siv feem ntau siv rau chrome plating
Qhov sib txawv loj tshaj plaws ntawm cov txheej txheem chromium plating thiab lwm txoj kev plating yog tias cathode tam sim no ceev ntawm chromium plating yog ntau dua li lwm txoj kev plating, feem ntau nyob ib ncig ntawm 30A / dm2. Thaum plating hniav chromium, qhov ceev tam sim no qis dua me ntsis. Qhov ceev tam sim no yog siab tshaj thaum plating nyuaj chromium. Yog li ntawd, rau chrome plated pendants, thawj qhov kev txiav txim siab yuav tsum tau hloov mus rau qhov siab tam sim no yam tsis muaj kev cuam tshuam cov conductivity vim cua sov. chrome plated pendant yuav tsum ua tau raws li cov cai hauv qab no:
(1) Cov khoom siv hluav taws xob ntawm cov cuab yeej dai yuav tsum tau ua los ntawm cov tooj liab ntshiab uas muaj qhov chaw seem txaus.
(2) Qhov kev sib cuag ntawm cov cuab yeej dai thiab cov khoom ua haujlwm yuav tsum tau txais txoj kev elastic clamping, thiab qhov chaw sib cuag yuav tsum me me. Thaum plating loj workpieces nrog nyuaj chromium, fixtures thiab hangers yuav tsum tau tsim raws li qhov loj, zoo, thiab qhov hnyav ntawm lub workpiece.
(3) Tsuas yog cov khoom siv sib txuas thiab cov khoom sib txuas nrog cov khoom ua haujlwm, lwm qhov ntawm lub hanger yuav tsum zoo insulated.
Tsim cov kev cai rau kev siv cov cuab yeej dai rau galvanizing thiab cadmium plating
Rau steel workpieces, zinc thiab cadmium txheej yog anodic txheej rau electrochemical tiv thaiv. Yog li ntawd, nws yuav tsum tau hais tias cov coatings yuav tsum tau them zoo, muaj ib tug tej yam thickness, thiab muab tusyees faib. Yuav kom ua tau raws li qhov xav tau saum toj no, galvanized thiab cadmium plated hangers yuav tsum ua raws li cov cai hauv qab no:
(1) Cov khoom siv hluav taws xob yuav tsum muaj cov conductivity zoo thiab ua los ntawm cov tooj liab ntshiab. Xav txog nws qhov teeb meem muaj zog. Cov hooks thiab lwm yam khoom siv rau dai workpieces tuaj yeem ua los ntawm cov hlau zoo tib yam.
(2) Zinc plating electrolytes feem ntau yog cov tshuaj alkaline zincate los yog cov tshuaj chloride. Txawm nyob rau hauv cov tshuaj chloride, nws tus nqi pH tsis qis thiab belongs rau cov acidity tsis muaj zog, yog li nws tsis muaj zog corrosion ntawm cov ntaub ntawv hlau. Yog li ntawd, cov kev xav tau ntawm corrosion kuj rau galvanized thiab chrome plated dai cov ntaub ntawv tsis nruj heev.
(3) Galvanized workpieces feem ntau yog cov khoom siv tshuab, nrog qee qhov muaj thaj tsam loj thiab qee qhov muaj qhov zoo. Txawm li cas los xij, thaum lub sij hawm galvanizing, lub anode tam sim no ceev tsis siab heev. Txhawm rau kom ntseeg tau tias lub thickness ntawm cov galvanized txheej yog zoo ib yam thiab tag nrho npog, lub workpiece mounting txoj hauj lwm yuav tsum tau hloov nyob rau hauv lub electroplating txheej txheem. Yog li ntawd, nws yuav tsum tau tsim thiab tsim cov cuab yeej dai yuav tsum yooj yim hloov thiab tsis tas yuav nruj heev.
(4) Thaum ua cov khoom dai, sim txo qhov chaw sib cuag kom ntau li ntau tau yam tsis muaj kev cuam tshuam rau kev teeb tsa ntawm thaj chaw sib cuag ntawm lub rooj sib txuas thiab cov khoom ua haujlwm, txhawm rau pab txhawb kev sib faib ntawm cov txheej txheem electroplating.
(5) Tsuas yog kev sib cuag nrog cov khoom ua haujlwm thiab cov khoom siv hluav taws xob, lwm qhov ntawm cov cuab yeej dai yuav tsum tau insulated kom tsis txhob muaj qhov tshwm sim ntawm lub zog rub ntawm lub dai dai thiab cov khoom ua haujlwm, uas yog qhov zoo rau kev txuag hluav taws xob thiab txhim kho kev tsim khoom.
