Electroplating mideyso biraha: technology, qalabka

Mideyso - wax ku ool ah oo jaban, oo sidaas daraaddeed jid caadi ah ee ilaalinta biraha ferrous ka daxalka. Xaaladaha intooda badan, waxaa loo isticmaalaa in soo saaridda ee hardware iyo qaybood ah, iyo mesh bir ah.

Hababka codsanaya daahan zinc ah

mideyso Anticorrosive sameeyaa siyaabo kala duwan, iyo nolosha adeeg ee daahan ee waxay ku xiran tahay dhumucda lakabka ilaaliya.

Habka A dahaadhka ku xiran tahay guryaha la doonayo, size sheyga, xaaladaha ay isticmaalka dheeraad ah.

The iska caabin aan ku filnayn ugu fudud oo manufacturable, laakiin waxay bixisaa si stress makaanikada ee lakabka ilaaliya, - a mideyso qabow via ciidda, taas oo ka kooban tiro badan oo ah budada zinc jar kala qaybsan.

By mugga saarka mideyso kaalinta labaad mideyso kulul-maquufin. daahan The helay sidan, tayo sare leh oo waarta, laakiin deegaanka ammaan ahayn, tan iyo markii dhalaalid zinc waxaa loo isticmaalaa, laakiin weli si ay u ilaaliyaan heerkulka yar yar ka badan 500 ° C baahan yahay xaddi weyn oo koronto, hababka kiimikada ee diyaarinta dusha.

Aad mid ah -maquufin kulul mideyso hab more farsamada, balse wax ka yar ku ool ah oo codsanaya lakabka ilaaliya ee sida- ee kaamerada. Waxa loo isticmaalaa marka dhigay dalabaadka sare ee dhumucda iyo maanka daahan dibadda ah.

Si kale oo mideyso - xereen gaas-kulka ah, kaas oo waxaa loo isticmaalaa ilaalinta waxyaabaha waaweyn iyo dhismayaasha in ay yihiin si fudud wax aan macquul aheyn in ay ku riday qubeyska.

Mideyso ka maqan badan oo ka mid ah khasaaraha ka mid ah hababka kale ee daahan oo uu leeyahay dhinaca wanaagsan.

Faa'iidooyinka mideyso

Habka A ee codsanaya daahan zinc ah by electrolysis badan yahay.

Faa'iidada ugu weyn, sababtoo ah taas oo galvanically waxaa laga codsadaa mideyso bir, waa heerka sare ee ilaalinta daxalka dusha ka mid ah waxyaabaha la. Lakabka A khafiif ah oo zinc waxay kordhisaa nolosha adeeg ee badeecada dhawr jeer, oo sidaas daraaddeed waxay yaraysaa kharashka dayactirka iyo bedelkiisa.

daahan The waa la helay, xataa iyada oo aan xariijimo iyo dhibco la hadhay qaabka iyo cabbirka of badeecada. Codso waxaa suurtagal ah in shay kasta, xataa qaababka ugu adag.

Siman iyo dhaldhalaalaan blaastiigga madaxtooyada uma baahna in kiisaska intooda badan daaweyn dheeraad ah.

Ka sokow, habka mideyso u baahan yahay kharash yar oo keliya, iyo isku celceliyo galvanic leeyihiin wax soo saarka sare.

Qasaaraha mideyso

Habka A codsan daahan difaac by electrolysis ma jiro khasaaro.

khasaare ugu weyn - Amda zinc si hoose bir, taas oo ay sabab u tahay dusha sare ee sheyga waa in si fiican loo nadiifiyo.

Dhinaca kale sidoo kale waa dhismaha ee geedi socodka daahan qashinka sunta ah ee u baahan nadiifinta halis ah.

hababka gaabinta keeni kartaa buuxinta bir waalidka la hydrogen, taas oo keenta in dabacsanaan ka mid ah wax soo saarka iyo carqalad ah oo tayo leh daahan.

Mabda 'hawlgalka

Mideyso ku saleysan yahay mabda'a of saamaynta ilaaliya, wixii la goostay by farqiga u awoodo electrochemical ee zinc iyo bir. Sida zinc leedahay awood hoose electrochemical, waxaa la dahaarka leh kula ilaalinta qurbaanka si Biraha ferrous. Taasi waa dhab waxa aanu la kulmin jawi qoyan daxalka electrochemical.

In lagu qayilo ee oxides birta loo sameeyay isagoo mugga weyn biraha asalka ah. film xabagta waxay noqonaysaa dabacsan oo ag maraaba in aan weli la oxidized oxygen biraha. Iyo zinc filimka lagu qayilo waxaa la aasaasay khafiif ah oo is haysta, waxa aanu gudubtid oxygen biraha ilaalinta ma aha oo kaliya daahan, laakiin sidoo kale biraha salka hoose.

Noocyada mideyso

Mideyso dahaadhay - technology, oo ka dhigan electrolysis ah, geedi socodka redox electrochemical ie in elektrolytka ee sarkhaansan hadda korontada joogto ah ...

On Halabuurka ee dahaadhay zinc elektrolytka wuxuu u qaybsan yahay saddex nooc: acid, alkali iyo cyanide.

The hab inta badan la isticmaalo ee codsanaya daahan zinc si imaanshada electrolytes acidic, gaar ahaan qaybo bir iyo bir ah qaabeynta adag. Products sameeyey oo carbon iyo daawaha steels la daahan zinc bandhigi dhacdo yar ee embrittlement hydrogen ah, iyo muuqaalka fiican waa la helay, oo leh saamayn madaxtooyada fiican in tiro balaadhan oo ah midabada.

ilaalinta dheeraad ah mideyso

tallaabo ay ku nabadgeli karaan daahan zinc ku xiran tahay oo dhumucdiisuna waxay, taas oo dhigaalka ah galvanic of 5 microns, iyo nooca elektrolytka ah.

Xaaladaha qaarkood, guryaha ilaaliya dahaadhka zinc ah kordhiyaa passivation, phosphating ama rinjiyeynta.

Passivation (chromating) - daaweynta kiimikada alaabta in xal of acid chromic ama cusbada oo dhanba, oo sabab u ah oo dusha sare sameeyay film chromate. Marxaladani waxay ma aha oo kaliya kordhisaa guryaha difaaca eyda badan, sababtoo ah iyadoo ay sabab u habaysan daahan gloss, oo waa la rinjiyeeyay karaa in midabo kala duwan.

Marka phosphating (daawaynta phosphoric acid ee cusbada) galvanized soo saarka ee dusha film phosphate sameeyay ka. Ka dib markii phosphating laga yaabaa in weli codsatay rinjiga.

marxaladaha mideyso

mideyso electroplating Production ka kooban yahay geedi socodka dhowr, kuwaasoo mid walba uu la joojiyo by lagu dhaqdo ee socda tubbada biyaha ama buraash dhaqidda iyo hab.

wax soo saarka ugu horeysay waxaa la taxadir leh loo nadiifiyaa of miridhku, miisaanka, labeen farsamada, coolant ama rinjiga harta iyo degreased ee xal alkali. Markaas maaddooyinka ku electrolytic.

Intaas ka dib Iambarrada in xal aqueous of Aashito kaas oo dusha kama dambaysta ah la nadiifin oo aan dhibi lakabka dusha sare iyo pickling ay dhacdo - hawshooda ka hor codsiga dahaadhka zinc ah. Kaliya ka dibna soo saaraan ay mideyso u gaar ah.

Ka dib markii in, haddii loo baahdo, caddeeyo iyo waxyaabaha la Daahiriyey filimka xabagta ku ah xal aqueous nitric acid, ka dibna phosphating, passivation iyo qallajinta.

hawlgallada dheeraad ah lagu samayn karaa iyadoo mideyso alaabooyin kala duwan. Tusaale ahaan, strip la unwound hor mideyso, darafyadiisa welded, guud ahaan ka dib markii a moofo saliid iyo boogta.

Qalabka mideyso

line korontada - isku xigxiga oo gaar ah oo bad-socodka iyo ku mayrin Kuwaas waxaa ku jira mancaha ama multilayer daahan zinc la guryaha functional doonayo.

Iyadoo la tixraacayo qalabka mugga wax soo saarka ee loo isticmaalo la darajo ah mechanization kala duwan. shirkadaha waaweyn ku hagaagaan khadadka matoorada leh gacanta si toos ah. Waxaa jira khadadka leh qayb ah ama buuxda gacanta buuggan iyo sidoo kale a mini-line.

line mideyso ka kooban tahay oo keliya ma aha ee bad. Waxaa ka mid ah nidaamka gaadiidka ee naqshado kala duwan, qalabka lagama maarmaanka u ah daawaynta biyaha wasakhaysan, qalabka kaabayaal, taas oo ka mid ah hab loogu talagalay mideyso, xubno ka kululaynta, exchangers kulaylka, cathode iyo ushii anode.

The siyaada ah waxaa ka mid ah nidaamyada hawo, armaajooyinka lagu qalajiyo iyo qalabka qaboojiyaha, qalabka filter, qaata bambooyin qalabka demivody.

Electrolytes for mideyso

Waayo, mideyso, taas oo ku xidhan ujeedada sheyga waxaa loo isticmaalaa electrolytes, kuwaas oo loo kala qaybiyey laba kooxood oo ugu waaweyn.

Electrolytes taas oo zinc waa qaab udhigo biyuhu fudud, loo yaqaan acid fudud. Tani fluoboric, sulfate iyo xalalka chloride.

dhafan electrolytes acidic iyo alkaline Complex ku jira udhigo zinc ee adag oo ah la kharash togan iyo kuwa taban. ammine Tani, pyrophosphate, cyanide iyo xal kale.

On oo elektrolytka ah waxaa laga codsadaa, waxay ku xiran tahay ugu horrayn on heerka dhigaalka ah, ka dibna tayada kayd ah zinc on maqaalka (cathode ah).

From electrolytes adag zinc shubo at cathode ee kala firidhsan sare ee udhigo. Iyada oo sii kordhaya biraha cufnaanta hadda hoos u dhalid iyo kordhiyaa dhalidda ee hydrogen.

Sidaa darteed mideyso in electrolytes adag sameeyo cufnaanta hadda hooseeyo, iyo daahan waa tayo aad u sare, grained u wanaagsan oo dhqaalaha.

In electrolytes imaanshada acidic zinc galvanic fudud, guriga ay ka mid yihiin, maraa at cufnaanta hadda sare, iyadoo ka badan marka la isticmaalayo heerka xal adag weyn. Imaansho ee alaabta ka helay waa wanaagsan tahay, laakiin daahan ah inaysan aheyn wax tayo aad u sarreeya oo ku haboon oo keliya qaabab wax soo saarka fudud.

mideyso

habka farsamada dhacdaa si toos ah qubeyska mideyso of elektrolytka. Waxaa laga saaray wax soo saarka madow biraha, kaas oo la quudin jiray iyada oo electrodes gaar ah koronto (cathode ah), iyo zinc saafi ah ama qaab ulo kubadaha buuxiyey oo qaybo mesh gaar ah (anode).

Inta lagu guda jiro dareen electrochemical sarkhaansan ah cufnaanta 1 korontada hadda ilaa 5 A zinc / dm kala diri ee elektrolytka ah, ka dibna udhigo ay shubo on cathode ah si ay u sameeyaan oo dhumucdiisuna waxay dahaadhay of 4-25 microns ah.

In uu yahay, iyadoo la isticmaalayo farsamada this waa la helay qaybood (handarraabbadeedii iyo nuts) la uniform iyo daahan dhaldhalaalaan.

Iswada line for mideyso

line mideyso Modern - waa line a si buuxda iswada, taas oo u qabata dhamaan tallaabooyinka daahan, oo ay ku jiraan alxanka iyo maaddooyinka alaabta tayada hawlaha iyo qaabeynta kala duwan.

line Automatic guud ahaan ka kooban yahay dhowr ah oo bad farsamada dahaadhay, rectifiers qaybsan, loading / waab dajinta, qalabka gaadiidka, Qalabka for hawo, biyo iyo dheecaan of wasakhda, birta la dayactirka sallaan.

bad Electroplating waxaa la samayn karaa ee ahama, birta, iyo jiidh leh bacyaal ama caag. qubeyska Modern, ka polymers sheet welded sii kordheysa bedelay daasadaha biraha. wax bad Xulashada waxay ku xiran tahay Halabuurka iyo ka-fiirsashada of elektrolytka iyo heerkulka ka hawlgala.

Communications qaybinta biyaha iyo nidaamyo bulaacada, oo kiisaska intooda badan u amro hoos bad hawo iyo sidoo kale ka polypropylene.

The dhinacyada line uu go'aamiyey awooda iyo dhinacyada bad galvanic.

Mideyso qaadataa meel la formation of biyaha qashinka la-fiirsashada sare ee udhigo biraha culus. Sidaa darteed, waxay u doode, sifeeyay, Kipury, iyadoo la isticmaalayo dhigaalka uumiga kiimikada, iyo talaabooyin kale oo sorption in weelasha of polymers injineernimada sameeyey.

electroplating Zinc guriga

Mideyso, soo saaray gacmaha iyaga u gaar ah, waxay ku bilaabmeysaa doorashada ee alaabta. elektrolytka waxay noqon kartaa xal of chloride zinc iyo aashito in biyo arimaha debeda. Tani waxa loogu yeero acid, kabida, taas oo inta badan la isticmaalo ee guriga. Saanacyadii Iambarrada zinc in sulfuric acid iyo batari diyaariyey ZnSO ₄ elektrolytka, laakiin habka tani waa halis ah, maxaa yeelay, falcelinta saarta kulaylka iyo hydrogen qarxa. elektrolytka The kiis kasta waa in aanay noqon dadajin a kiristaalo cusbo beelaya.

zinc saafi ah laga iibsan karaa dukaanka a of reagents kiimikada ama raadiyaha, iyo waxaa laga heli karaa batari waa inay cusbo ama fiyuusyada, ka Midowga Soofiyeeti sii raagayaan.

qubeyska Galvanic noqon kartaa galaas ama weel caag ah. Waxay u taagan tahay in ay u dhigay, anode iyo cathode. anode The - saxan zinc ah, taas oo ku xiran ka korontada ah "oo lagu daray". The more anode ah, daahan ayaa in ka badan labis on saarka cathode oo waxaa laga codsadaa daahan difaaca ah. anode waxaa laga yaabaa in wax yar, waxay waxaa lagu qori karaa hareeraha cathode ka fogaan isla inay dusha sare ee zinc ah dahaarka isku oo isku mar on dhinacyada oo dhan. Si cathode ah oo ku xiran "jaray" il awoodeed.

Xataa marka guriga lagu sameeyo mideyso technology dahaadhay daruuri ka mid ah nadiifinta dhamaystiran iyo xayraynta qaybaha, iyo sidoo kale ay hawshooda u ah ee xal acid.

Supply Power - taasi waa batari gaari oo wata siraad incandescent awoodda yar ama macaamiisha kale soo wareegi jiray si uu hadda ku soo wareegi jiray hoos ku ahayd ama korontada la danab joogto ah ee wax soo saarka. Waxa ugu muhiimsan waa in aanay jirin karaya deg deg ah ee elektrolytka lagu jiro mideyso ah.

Dhab ahaantii mideyso wuxuu dhacaa marka ay anode iyo cathode waxaa laga saaray in elektrolytka iyo circuit korontada xiran yahay. The dheer habka, ka sii dhumuc weyn ee lakabka zinc ka helay on sheyga.

Iyada oo mideyso daahan difaaca on sheyga uu noqdo saxda ah, labis iyo siman, la saamayn madaxtooyada. Waxa loo isticmaalaa labadaba warshadaha iyo guriga, inkastoo xaqiiqda ah in ay qaadato biyaha daata ka qashinka deegaanka khatarta ah.
