Daim Ntawv Thov ntawm Titanium Thiab Titanium Alloy Hauv Electroplating Kev Lag Luam
Nyob rau hauv cov xwm txheej ntawm cov npib tsib xee plating, zinc plating, tooj liab plating thiab ntau lwm yam mob, electroplating da dej yog ua los ntawm cov hlau nrog tawv polyvinyl hauv ob sab phlu thiab txhawb los ntawm tus ncej hauv cov electrolyte. Txawm li cas los xij, nyob rau qhov kub siab dua, cov tawv polyethylene tawg vim cov cua sov nthuav dav (qhov coefficient ntawm thermal nthuav ntawm tawv polyethylene yog 6 npaug ntau dua li ntawm cov hlau), thiab kev ncaj ncees ntawm lub hauv ob sab yog puas (tshwj xeeb hauv thaj chaw vuam). ), qhov tshwm sim yog tias cov khoom siv da dej yog corroded thiab infertile, uas paug cov roj electrolyte. Txawm hais tias qhov ntau npaum li cas ntawm cov khoom lag luam hauv corrosion (qhov sib xyaw ntawm cov hlau loj) tsis tseem ceeb. Qhov no yog ib qho piv txwv ntawm kev txhim kho qhov zoo ntawm lo. Cov txiaj ntsig ntawm kev siv cov roj hmab ua ib lub hauv paus yog me me, vim tias cov roj hmab sai sai Ua Ntej. Cov txheej txheej txheej txheem thiab txheej txheem txheej txheem thov cov txheej txheem nyias roj hmab yog qhov nyuaj vim tias kev nplaum tsis zoo rau qee cov hlau. Siv tag nrho cov khoom siv roj hmab uas twb muaj lawm kev tiv thaiv kev tiv thaiv thiab kev tiv thaiv rwb thaiv tsev, tus pas nrig siv tsuas yog siv tau hauv lub sijhawm 2 mus rau 3 lub hlis thaum cov cua vinyl xim lossis cov vinyl cua siv. Nws yog qhov tsis yooj yim los hloov thiab kho qhov tawg nrog ntau qhov hnyav ntawm kev ua haujlwm.
Cov tshuab siv tshuab electroplating feem ntau tuaj yeem plated rau hauv ntau txheej xim hlau. Raws li peb txhua tus paub, electroplating muaj keeb kwm muaj ntau dua 100 xyoo. Nws yog ib hom electrochemical dhau-kneading, uas yog txheej txheem ntawm kev tso cov hlau yuav tsum tau lossis txheej txheej ntawm cov hlau thiab cov hlau tsis xau los ntawm electrolysis. Nws yog cov tshuab hluav taws xob ua hluav taws xob rau kho kom zoo nkauj thiab qee yam khoom tshiab. Cov. Nyob rau lub sijhawm tam sim no, nws tau tsim los ntawm kev kho saum npoo ntawm cov hlau mus rau qhov ua tau ntawm txheej hlau txheej ntawm qhov chaw tsis yog xim hlau (xws li cov hniav yas), siv cov txheej txheem electrodeposition los kho cov khoom ua haujlwm dhau los, thiab lwm yam. Electrodeposition tam sim no tau tsim los ntawm cov hlau ntawv rau hauv txheej hlau thiab hlau ua txheej. Lub ntsiab lus ntawm electroplating kuj tseem niaj hnub tsim thiab nthuav dav. Nws yog dav siv hauv kev siv tshuab, ntsuas khoom siv, khoom siv hluav taws xob, lub teeb pom kev lag luam, kev thauj mus los thiab kev tiv thaiv kev lag luam, thiab lwm yam, los txhim kho cov khoom lag luam zoo nkauj, dai kom zoo nkauj thiab ua kom zoo nkauj khoom, thiab txhim kho lub peev xwm tiv thaiv kev ua lag luam ua lub luag haujlwm tseem ceeb hauv txuas ntxiv kev pabcuam lub neej ntawm cov khoom. Electroplating tso siab rau kev siv ntau yam khoom siv hluav taws xob tshiab, nce qhov kub thiab nce qhov tam sim no kom ntseeg tau tias cov khoom lag luam ntau ntawm cov txheej txheem electroplating zoo dua thiab cov txheej txheem muaj zog dua. Yog li ntawd, nws yog qhov yuav tsum tau ua kom nruj rau cov txheej txheem cov ntoo ntawm cov cuab yeej siv hauv kev siv tshuab electroplating. Yuav tsum muaj. Ntxiv rau kev txhim kho txuj ci kev ua haujlwm, nce kev pab lub neej ntawm ntau yam cuab yeej yog qhov tseem ceeb. Qhov no txhais tau hais tias cov ntaub ntawv teeb tsa thiab txheej txheej yuav tsum siv ua ntej.
Hauv cov electrolytes siv hauv npib tsib xee plating, tooj liab plating, cadmium plating, zinc plating, tooj dag plating, thiab nyiaj plating, titanium yog xyaum tsis raug rau xeb teeb meem tshwj tsis yog muaj boron hydrogen fluoride lossis vaporized hydrogen acid (hydrofluoric acid). yaig. Nws tsis pom zoo kom siv cov titanium hauv qhov nruab nrab uas muaj fluoride ions, vim tias qhov xeb thaum lub sij hawm txiav tawm tam sim no yog 5 hli / A, thiab thaum lub kaw lus anode tig, nws loj dua 30 hli / A. Nyob rau lwm lub sijhawm, siv titanium alloy da dej tsis muaj taug txhuas. Cov txheej txheem lossis tawv tawv PVC lined steel da dej yog qhov tsim nyog, vim hais tias cov txheej txheem tuaj yeem ruaj khov vim yog kev txij nkawm txo qis txhua hnub, thiab cov pa ntshiab huv tau txais kev tswj hwm txhawm rau txhim kho cov txheej txheem kom zoo.
Txawm hais tias muaj ntau cov txheej txheem ntawm cov khoom siv los tiv thaiv cov khoom siv, electroplating yog kev lag luam kev lag luam uas tsim cov dej tsis huv, cov roj pov tseg thiab cov khib nyiab pov tseg, uas ua rau muaj kuab paug rau ib puag ncig, thiab kev xeb ua haujlwm thiab kav ntev ntawm cov khoom siv electroplating tsis tau thaum kawg daws tau. Yog li ntawd, thev naus laus zis thev naus laus zis koom nrog ntau yam kev qhuab qhia, xws li physics, chemistry, machinery, tshuab hluav taws xob, thiab lwm yam. Nws tseem muaj cov txheej txheem ntawm cov txheej txheem thev naus laus zis. Yog li ntawd, ntawm ib sab, nws yog ib qho tsim nyog los txuas ntxiv txhim kho qhov zoo ntawm electroplating, thiab ntawm qhov tod tes, nws yog ib qho tsim nyog los tiv thaiv ib puag ncig rau cov tiam tom ntej. txiaj ntsig. Qhov no yuav tsum tau siv engineering thiab cov neeg ua haujlwm koom nrog electroplating los txhim kho theem ntawm kev tshawb fawb thiab thev naus laus zis, txuas ntxiv tsim kho tshiab thev naus laus zis, nthuav dav qhov dav ntawm kev siv cov thev naus laus zis tshiab tshiab, tshem tawm cov pa phem, txo zog ua kom tsis muaj zog, txhim kho kev ua haujlwm ntawm cov neeg ua haujlwm, thiab tshem tawm kev xeb ntawm cov khoom siv los ntawm electroplating cov txheej txheem. Hmoov txhuas yog cov tshuaj nyob ruaj khov rau hauv chromium plating electrolytes thiab lwm yam khoom siv hluav taws xob ntau, tab sis cov hlau lead muaj qhov tsis tshua muaj neeg lub zog. Nyob rau hauv cov xwm txheej ntawm kev rov ua dua ntawm kev siv cov ntawv txhuas, lub electroplating tank lub cev corroded loj.
Vim tias titanium alloy muaj kev txhim kho corrosion nyob rau hauv ntau cov electrolytes uas tau hais los saum toj no, nws muaj peev xwm kom txo cov phab ntsa tuab ntawm qhov cub electrolytic los ntawm 1/2 lossis ntau dua. Yog li ntawd, tus nqi ntawm titanium alloy da dej thiab hlau da dej nrog lub zog polynitrogen hauv ob sab phlu yog qhov zoo ib yam. Piv txwv, tus nqi ntawm cov da dej steel nrog lub ntim ntawm 1m3 thiab tawv tawv hauv PVC txheej yog 4200 yuan, thaum tus nqi them rau titanium alloy da dej nrog tib ntim yog 5000-6500 yuan; tus nqi ntawm ib da dej steel nrog lm3 ntim thiab tawv PVC txheej yog 3000 yuan Yuan, thaum lub dab da dej ua los ntawm titanium alloy nrog tib lub ntim yog 3700-5000 yuan. Lub sijhawm no, kev pabcuam lub neej ntawm titanium alloy chav dej da dej tau nce ntau tshaj li 5-6 zaug. Kev siv ntau cov khoom siv ntawm cov titanium alloys tuaj yeem daws cov teeb meem ntawm kev xaiv cov khoom siv rau kev tsim cov khoom siv nrog kev txhim kho siab hauv cov electrolytes feem ntau.
