Zinc-plated zvinhu

Wakamboona chero chinhu pamusoro pesimbi chine orange-brown?Inonzi ngura, muvengi akaipisisa wesimbi, uye inokonzerwa nekuita kweferrous metal molecules nehunyoro.Ngura inokonzeresa kuparara kwezvinhu uye pakupedzisira inobatsira mukutadza kwezvigadzirwa uye mekiniki zvikamu.Zinc platinginoshandiswa kugadzirisa dambudziko rekugadzira ngura nekugadzira chipingamupinyi chakaonda pamusoro, chichidzivirira kubva mukuora paunenge uchisangana nenharaunda.

Muchikamu chino, tichapfuurakushanda kwe zinc plating, matanho anosanganisirwa, anokanganisa mashandisirwo ezvinhu, zvakanakira, uye zvisingakwanisi.

Chii chinonzi Zinc Plating?

Imwe nzira yekupedzisa pamusoro peiyo ferrous zvinhu zvikamu uye zvigadzirwa ndeye zinc plating.Zvinosanganisira kuwedzera mutete pasi pasi pasina kukanganisa kugadzikana kwedimensional, zvichisiya nzvimbo yakatsetseka, isina grey.Zinc plating inopa yakanakisa aesthetic kukwezva kune zvigadzirwa, asi kupfuura izvozvo, inoita kuti zvigadzirwa zvigadzirise ngura.Iyo zinc plating process inogadzira yakatetepa inodzivirira yakavhara ne electrodepositing zinc pasimbi inozovharwa, inonziwo substrate zvinhu.

Zinc plating inoshanda sei?

Kana zinc plating yaiswa kumhepo, inopindirana neokisijeni sezvinoita masimbi ane ferrous uye inogadzira zinc oxide (ZnO), iyo inobva yasangana nemvura kugadzira zinc hydroxide (ZnoH).

Kumonyoroka kwacho kunouya iko zvino kana atmospheric carbon dioxide ne zinc oxide zvasangana kuita chitubu chitete chezinc carbonate (ZnCO3) chinonamira pazinc yepasi uyezve kuchidzivirira kubva mukuora.

Matanho Akabatanidzwa muZinc Plating

1.          Kuchenesa kwepamusoro

Danho rekutanga pakugadzira zinc kuchenesa nzvimbo ichaiswa guruva kuti ibvise huruva, oiri, uye ngura kuitira kuti pamusoro pave kuzora zingi zvakanaka.Pakuchenesa, alkaline detergents ndiyo yakanakisisa inoshandiswa iyo isingazodzikisi pasi.Nekudaro, kuchenesa asidhi kunogona kuiswa usati washandisa alkaline detergents.

Kugezera pakati pe100 ne180 degrees C kunobatsira kubvisa grime usati washandisa alkaline detergent ye micro-level yekuchenesa.Mushure mekuchenesa nealkaline detergent, sukurudza nzvimbo yacho nekukasira nemvura yakadirwa kudzivirira kukuvadza nzvimbo yekutanga, iyo alkaline mhinduro inogona kukuvadza.Kana iyo yekucheneswa kwepamusoro ikasaitwa nemazvo, Inogona kukonzera iyo Zinc coating kuti iparadze kana kukuvara.

2.          Pickling

Maokisi akawanda, kusanganisira ngura yakatoumba, inogona kunge iri pamusoro.Naizvozvo, zvakakosha kushandisa zvigadziriso zveasidhi kubvisa maokisi uye zviyero usati waenderera mberi nekuisa zinc.Iwo maviri akajairika mhinduro anoshandiswa mukuita uku sulfuric uye hydrochloric acid.Zvigadzirwa zvakanyudzwa mune iyi acid mhinduro.Nguva yekunyudza, tembiricha, uye Concentration yemaasidhi zvinoenderana nerudzi rwesimbi uye ukobvu hwezvikero.

Kutevera pickling nekunyudza zvikamu muine acid solution, pakarepo chenesa nemvura yakasvibiswa kudzivirira chero kuita kwechisimba uye kusvibisa pamusoro.

3.          Kugadzirira kugeza plating

Danho rinotevera kugadzirira mhinduro ye electrolytic ye electroplating process, inozivikanwawo seyokugezera yekugezera.Iyo yekugezera ndeye ionic zinc mhinduro inobatsira mukugadzirisa maitiro ekuputira.Inogona kunge iri acid zinc kana alkaline zinc;

Acid zinc: Kushanda kwepamusoro, kukurumidza kuisa, simba rekuvhara rakanakisa, asi simba rekukanda rakashata uye kugova kusina simba kugovera.

Alkaline zinc:Yakanakisa ukuru kugovera nesimba repamusoro rekukanda, asi kushomeka kweplating, yakaderera electro-deposition rate,

4.          Electrolysis Setup & Kusuma yazvino

Zinc-plating setup

Iyo chaiyo deposition process inotanga nekusuma magetsi emagetsi (DC) mushure mekusarudza electrolyte zvichienderana nezvinodiwa nechigadzirwa uye zvakatemwa.Zinc inoshanda seanode uye inosanganiswa kune substrate's negative terminal (cathode).Zinc ions inobatana necathode (Substrate) semagetsi emagetsi anoyerera nepakati pema electrolytes, achiita chivharo chakatetepa chezinc pamusoro.

Pamusoro pezvo, kune nzira mbiri dze electrolysis: rack plating uye barrel plating (Rack & Barrel plating).

·   Racks:Iyo substrate inonyikwa mu electrolyte ichibatanidzwa kune rack, Yakakodzera zvikamu zvakakura

·   Barel:Iyo substrate inoiswa mudhiramu uye yobva yatenderedzwa kuti iwane yunifomu yekuputira.

5.          Post-processing

Kuti ubvise chero kusvibiswa kunogona kuitika pamusoro, zvikamu zvinofanirwa kucheneswa nemvura yakanyungudutswa kakawanda mushure mekupedzwa kwekuputira.Usati watumira zvigadzirwa zvakaputirwa zvekuchengetedza mushure mekugeza, zvinofanira kuomeswa.Kana zvichidikanwa, passivates uye sealants zvinogona zvakare kushandiswa zvichibva pane inodiwa zviyero zvekupedzisa pamusoro.

Zvinhu zvinofanira kufungwa nezvazvo

Kuziva chinhu chacho kuchabatsira kudzora maitiro uye kuwana yakakwana plating.Zvinhu zvakawanda zvinokanganisa mhedzisiro yekuisa pane substrate.

1.          Current density

Iyo zinc layer thick, iyo inoda kuiswa pa substrate surface, inobatwa ne density yezvino ichipfuura nema electrode.Naizvozvo, Yepamusoro Parizvino ichagadzira mukobvu wakakora ukuwo yakaderera ichigadzira yakatetepa layer.

2.          Kupisa kwekugezera bhati

Chimwe chinhu chinokanganisa zinc plating ndeye tembiricha ye electrolysis solution (Pating bath).Kana tembiricha yakakwira cathode inoshandisa ma hydrogen ions mashoma kubva mumushonga uku panguva imwe chete ichitora zvimwe zvinopenya kuitira kuti zinc plating ijeke nekuda kwekuiswa kwepamusoro kwesimbi yecrystal ye zinc.

3.          Iyo Concentration ye zinc mune yekugezesa yekugezera

Iyo zinc yekumisikidza mubhavhu replating zvakare inokanganisa magadzirirwo eplating uye dhigirii rekupenya.Semuyenzaniso, nzvimbo yakakasharara inozobva mukuwanda kwazvo nekuti zinc ions inogovaniswa zvisina kuenzana uye inoiswa nekukurumidza.Nekune rimwe divi, iyo Yakaderera yekumisikidza inozokonzera kupenya kupenya nekuti makristasi akanaka anozoiswa zvishoma nezvishoma.

Zvimwe zvinhu zvinosanganisiraiyo nzvimbo yeElectrodes (anode & cathode), iyo substrate yemhando yepamusoro, iyo Concentration yeva surfactants uye inopenya mubhavhu rekuputira, kusvibiswa., nezvimwe.

Zvakanakira

Pamusoro pekudzivirira ngura, zinc plating ine akati wandei mabhenefiti;ngatiendei pamusoro pevashoma netsanangudzo pfupi.

·        Mutengo wakaderera:Iyo ndiyo inodhura-inoshanda nzira yekupedzisa kwepamusoro kana ichienzaniswa nedzimwe nzira, dzinosanganisira poda coating, black oxide kupera, uye sirivheri plating.

·        Simbisa:Iyo zinc yekuputira pasimbi, mhangura, ndarira, uye mamwe ma substrates anobatsira kuwedzera kusimba kwezvinhu izvozvo.

·     Dimensional kugadzikana:Kuwedzera zinc layer hakukanganise zvikamu 'kana zvigadzirwa' dimensional kugadzikana,

·        Aesthetic beauty:Mushure mekuputira, iyo substrate yepamusoro ichaita seyakajeka uye inoyevedza, uye mavara anogona kuwedzerwa mushure mekugadzirisa.

·        Ductility:Nekuti zinc isimbi inodonhedza, kuumba iyo iri pasi pe substrate inoitwa nyore.
