Nei Cyanide ichinetsa kutsiva muIndasitiri yeElectroplating?

The electroplating indasitiri yagara ichitsamira pairi Cyanide-yakavakirwa mhinduro, uye kunyangwe kuedza kutsvaga dzimwe nzira, cyanide inoramba iri chinhu chikuru mune dzakawanda electroplating maitiro. Ichi chinyorwa chinoongorora zvikonzero nei cyanide yakaoma kutsiva muindasitiri ye electroplating.

Izvo zvakakosha zveElectroplating

Electroplating chirongwa chinosanganisira kuisa chidimbu chitete chesimbi pane substrate kuburikidza nekupfuura magetsi kuburikidza nemushonga we electrolyte une maion esimbi. Ioni dzesimbi mumhinduro dzinokwezvwa kune yakashata chaji substrate (the cathode), apo vanowana maerekitironi uye vanoiswa sesimbi yakasimba coating.

Basa reCyanide muElectroplating

Cyanide compounds, zvakadai Sodium cyanide uye potassium cyanide, inowanzoshandiswa mukugezera electroplating nekuda kwezvikonzero zvakakosha:

Yakasarudzika Yakaoma Mano

Cyanide ions (CN⁻) ine hunyanzvi hunoshamisa hwekugadzira macomplexes akatsiga nemaoni esimbi. Mu electroplating, ichi chivakwa chinodiwa zvakanyanya sezvo chichibvumira kunyatso kudzora pamusoro peiyo yemahara simbi ions mu electrolyte. Nekugadzira simbi-cyanide complexes, kuwanikwa kweioni dzesimbi dzemahara kunodzikiswa, izvo zvinozodzikisa pasi deposition rate yesimbi pane substrate. Iyi inodzorwa deposition inoguma mune imwe yunifomu uye inonamatira simbi coating.

Semuenzaniso, kana electroplating sirivheri, kuumbwa kwesirilver-cyanide complex (Ag(CN)₂⁻) kunogadzirisa zvakanyanya maion esirivha mumushonga. Uku kugadzikana kunodzivirira kukurumidza uye kusingadzoreki kuiswa kwesirivheri, izvo zvingave zvichitungamira kune yakashata-mhando, isina kuenzana coating. Kugadzikana kwepamusoro kwesirivha-cyanide complex inovimbisa kuti ion sirivheri inosunungurwa zvishoma nezvishoma uye zvishoma nezvishoma panguva ye electroplating process, zvichiita kuti pave nekugadzirisa uye kugadzikana kwekuisa pane cathode.

Yakavandudzwa Coating Hunhu

Kushandiswa kwe cyanide mumabhati e electroplating kunowanzoita kuti pave nekuumbwa kwezvipfeko zvine unhu hwepamusoro. Iyo inononoka uye inodzorwa deposition inofambiswa ne cyanide complexes inokonzeresa machira akanyanya kusimba, anotsvedzerera, uye anonamatira zvirinani kune substrate. Aya machira anoratidza kukwidziridzwa kwekuramba, kupfeka kuramba, uye kukwezva kweanoyevedza zvichienzaniswa neakawanikwa achishandisa dzimwe nzira dzekuisa.

Kana iri goridhe replating, maelectrolyte ane cyanide anogonesa kuiswa kwegoridhe rakatetepa, rakafanana rinonamira zvakasimba kusimbi iri pasi. Izvi zvakakosha mumashandisirwo akadai sekugadzira zvishongo uye zvemagetsi, uko kwemhando yepamusoro, yekugara kwenguva refu yegoridhe yakakosha. Kushandiswa kwecyanide kunobvumira kugadzirwa kwejasi risingangotaridzi chete asiwo rinoshanda zvakanyanya, rinosangana nezvinodiwa zvakasimba zvemaindasitiri aya.

Wide Kushanda

Cyanide-based electroplating process inosiyana-siyana uye inogona kuiswa kune dzakasiyana siyana dzesimbi uye substrates. Zvinonyanya kushanda pakuputira simbi dzinonetsa kuisa uchishandisa dzimwe nzira, dzakadai segoridhe, sirivheri, mhangura, uye zingi. Iko kugona kwecyanide kuumba yakagadzika macomplexes neaya masimbi anoita kuti ive sarudzo yakanaka yekuwana emhando yepamusoro machira mune akasiyana maindasitiri ekushandisa.

Kungave kuri kuputira kwakapfava zvinhu zvemagetsi kana zvikamu zvakakura zveindasitiri, cyanide-based electroplating yakaratidza kuve yakavimbika uye inoshanda nzira. Maitiro acho anogona kugadzirwa kuti asangane nezvinodiwa chaizvo zveakasiyana substrates uye maapplication, zvichiita kuti ive sarudzo inosarudzika kune vakawanda vanogadzira.

Matambudziko Pakutsiva Cyanide

Pasinei nekunyanya kuzivikanwa kwehupfu hwecyanide, kuedza kugadzira dzimwe nzira dzinoshanda kwakatarisana nematambudziko makuru:

Performance Gap

Mazhinji mamwe machemistries ekuputira akatsanangurwa, asi vashoma vakakwanisa kuenzanisa mashandiro ecyanide-based masisitimu maererano nemhando yekupfeka, deposition rate control, uye kuita zvakasiyana. Zvisiri-cyanide dzimwe nzira dzinowanzonetsekana kuti dziwane chiyero chakafanana chekufanana, kunamatira, uye kusagadzikana kwekuora semachira ane cyanide.

Semuyenzaniso, mamwe asiri-cyanide sirivha plating maitiro anogona kukonzera machira ane porous uye asinganyanyi kuomerera, zvichiita kuti zvinyanye kubatwa nekuora uye kupfeka. Iyi mipimo yekuita inogona kuve yakakura dhizaini mumashandisirwo apo kutendeseka uye kusimba kwejasi kwakakosha.

Kufungisisa kweMutengo

Kugadzira uye kuita hutsva husiri hwecyanide electroplating matekinoroji kunogona kudhura. Mutengo wekutsvagisa nekusimudzira, pamwe nekudikanwa kwekugadzirisa midziyo yeplating iripo uye maitirwo, zvinogona kuunza chipingamupinyi chakakosha pakutorwa kwemakambani mazhinji emagetsi. Mune zvimwe zviitiko, mari yemamwe makemikari inogonawo kunge yakakwira kupfuura iyo cyanide, zvichiwedzera kumatambudziko ehupfumi.

Madiki uye epakati-saizi electroplating mabhizinesi, kunyanya, angaomerwa kururamisa mari inodiwa kuti uchinje kune isiri-cyanide plating nzira. Mhedzisiro yezvemari yeshanduko yakadai inogona kuva chidziviso, kunyanya mumusika wemakwikwi uko kudzora mutengo kwakakosha.

Process Kugarisana

Kuchinjira kune isiri-cyanide electroplating ingada shanduko dzakakura kune dziripo dzekugadzira maitiro, kusanganisira kugadziridzwa kune yekuisa yekugezesa maumbirwo, mamiriro ekushanda, uye nzira dzekurapa tsvina. Kuve nechokwadi chekuenderana nemidziyo yazvino uye mitsara yekugadzira inogona kuve yakaoma uye inopedza nguva basa, uye chero kukanganisa kunzira yekugadzira kunogona kukonzera kurasikirwa kwechigadzirwa uye kuwedzera mitengo.

Uyezve, tsvina inogadzirwa kubva kune isiri-cyanide electroplating maitiro inogona kuva neunhu hwakasiyana pane iyo kubva kune cyanide-based process, inoda kugadzirwa kwemarara matsva uye nzira dzekurasa. Izvi zvinowedzera imwe nhanho yekuoma kunzira yekuchinja.

mhedziso

Mukupedzisa, nepo kuchetura kwecyanide kwakakurudzira kutsvaga dzimwe nzira dze electroplating, zvimiro zvayo zvakasiyana uye mabhenefiti ekuita zvakaita kuti zviome zvakanyanya kutsiva muindasitiri yemagetsi. Kugona kwecyanide kugadzira simbi dzakagadzika masimbi, kuwedzera kunaka kwekupfeka, uye kuiswa mukati memhando dzakasiyana dzesimbi uye substrates inoenderera mberi ichiiita chinhu chakakosha mukushanda kwakawanda kwe electroplating.

Zvakadaro, kuzvipira kweindasitiri kukuchengetedza kwezvakatipoteredza uye kuchengetedzeka kwevashandi kunoreva kuti kutsvaga kunoshanda kune dzimwe nzira dzisiri dzecyanide pasina mubvunzo kuchaenderera. Sezvo tekinoroji ichifambira mberi uye makemikari matsva anogadzirwa, pane tariro yekuti rimwe zuva kutsiva kwecyanide mu electroplating kwechokwadi kunoshanda uye kunodhura. Kusvika panguva iyoyo, iyo electroplating indasitiri inozoda kunyatso gadzirisa mashandisirwo ecyanide, kuita matanho akasimba ekuchengetedza uye kurapwa kwemarara kwakaringana kudzikisa kukanganisa kwayo pahutano hwevanhu uye nharaunda.
