Ndezvipi zvinhu zvinowanzobata sodium cyanide mhangura plating?

Sodium cyanide Copper plating itsika electroplating nzira inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, kunyanya mumagetsi uye kugadzira zvishongo. Iyi nzira inosanganisira kushandiswa kwe Plating solution iyo inoshanda seyakaomesesa agent, inonyanya kuumbwa necopper ions uye imwe chiyero che Yemahara cyanide, zvese zvakachengetwa munzvimbo ine alkaline yakasimba. Kunyange iyi nzira yakaratidza kushanda, zvinhu zvakati wandei zvinogona kukanganisa zvakanyanya kunaka kwechigadzirwa chekupedzisira. Kunzwisisa zvinhu izvi kwakakosha pakugadzirisa maitiro ekuputira uye kuve nechokwadi chemhando yepamusoro mhedzisiro.

1. Kupisa Kwekupisa

Chimwe chezvinhu zvinonyanya kukosha zvinokanganisa Sodium cyanide copper plating ndiyo tembiricha yemushonga weplating. Tembiricha yakaringana pakuita uku kunowanzova pakati pe50°C kusvika pa65°C. Mukati memhando iyi, iyo cathode ikozvino inoshanda inowedzerwa, ichitungamira kune imwe yunifomu uye yepamusoro-mhando yemhangura dhipoziti.

Kana tembiricha yanyanya kuderera, iyo cathode ikozvino inoshanda inodzikira, zvichikonzera hurombo hwekuisa mhando. Sezvineiwo, tembiricha yakawandisa inogona kutungamira mukuora kwemhinduro yeplating, ichigadzira zvisingadiwe byproducts senge sodium carbonate uye ammonia. Izvi byproducts zvinogona kukanganisa plating maitiro uye kunaka kweyekupedzisira yekupfeka. Naizvozvo, kuchengetedza tembiricha yakakodzera kwakakosha kuti uwane mhedzisiro yeplating yakakwana.

2. Current Density Management

Yazvino density ndechimwe chinhu chakakosha chinokanganisa kugona uye kunaka kwe Sodium Cyanide copper plating. Current density zvinoreva huwandu hwemagetsi anoshandiswa pachikamu chechikamu che cathode. Kuwedzera density iripo kunogona kutungamira mukuderedzwa mune ese ari maviri cathode uye anode ikozvino kushanda.

Kana iyo anode yazvino density ikakwira zvakanyanya, inogona kukonzera anode passivation, mamiriro ekuti anode iite shoma uye inotadzisa maitiro ekuisa. Kuti udzikise nyaya iyi, kushandiswa kwe periodic commutation power supply kunogona kubatsira. Iyi tekinoroji inobvumira kuwedzera kunodzorwa kwehuwandu hwazvino, huchigonesa manejimendi ari nani eiyo plating process uye yakagadziridzwa kunaka kwekupfeka.

3. Basa reCyclic Reversing Power Supply

Kuitwa kweiyo cyclic reversing power supply mu electroplating process inogona kuwedzera zvakanyanya kunaka kwemhangura yekuputira. Iyi nzira inobvumira kugadziriswa kweanode ikozvino density, iyo inogona kutungamirira kuderedzwa kweporosity yekuputira. Iyo ine porous coating isinganyanyi kudiwa, sezvo ichipa dziviriro iri nani kubva mukuora uye inovandudza kusimba kwese kwenzvimbo yakapfava.

Pamusoro pezvo, kushandiswa kweiyo cyclic inodzosera magetsi magetsi kunogona kusimudzira kuita kwemazinga emhinduro yekuisa. Nekuwedzera diki simbi yemunyu inopenya kune mhinduro, zvinokwanisika kuwana inopenya mhangura yekuputira ine yakanakisa kuenzana maitiro. Uku kusanganiswa kwematekiniki kunogona kukonzera kupera kwemhando yepamusoro kunosangana nezvinodiwa zvekushandisa kwakasiyana siyana.

4. Kusachena uye Kutarisira Kwazvo

Kuvapo kwetsvina mumushonga weplating kunogona kukanganisa kunaka kwemhangura yemhangura. Imwe yetsvina yakajairika inowanikwa mukati sodium cyanide copper plating is carbonate. Kana iyo carbonate yemukati ichipfuura 70g/L, zvakakosha kuibvisa kuchengetedza kutendeseka kweiyo plating process.

Iyo yakajairwa nzira yekubvisa yakawandisa kabhoni inosanganisira kutonhodza mhinduro yeplating kusvika pazasi 0 ° C, ichibvumira iyo carbonate kupenya zvakangoita. Kunyange zvazvo nzira iyi yakananga uye inoshanda, zvakakosha kuziva kuti inenge 10% yesimbi yemunyu inogona kurasikirwa panguva yekristalllization process. Naizvozvo, kunyatsotariswa kunofanirwa kupihwa kune manejimendi etsvina kuti ive nechokwadi chekuti mhinduro yeplating inoramba ichishanda uye kuti mhando yechigadzirwa chekupedzisira haina kukanganisa.

mhedziso

Sodium cyanide copper plating inzira inoshandiswa zvakanyanya electroplating iyo inopa akawanda mabhenefiti maererano nekubudirira uye kunaka. Nekudaro, budiriro yeiyi nzira inotsamira zvakanyanya pazvinhu zvakati wandei zvakakosha, zvinosanganisira kudzora tembiricha, ikozvino density manejimendi, kushandiswa kwecyclic reversing magetsi, uye manejimendi etsvina.

Nekunzwisisa uye nekugonesa zvinhu izvi, vagadziri vanogona kusimudzira kunaka kwemhangura yavo yekupfeka, kuve nechokwadi chekuti vanozadzisa zvakaomesesa zvinodikanwa zvemaindasitiri akasiyana. Sezvo tekinoroji ichienderera mberi, tsvakiridzo inoenderera mberi uye budiriro mumunda we electroplating ingangotungamira kune imwe gadziriso mu sodium cyanide copper plating process, ichigadzira nzira yemhando yepamusoro uye nzira dzekugadzira dzinoshanda.

Muchidimbu, kungwarira manejimendi ekushisa, density yazvino, nzira dzekupa magetsi, uye mazinga ekusachena kwakakosha kuti uwane mhedzisiro yakakwana mu sodium cyanide copper plating. Nekutarisa pazvinhu izvi zvakakosha, vagadziri vanogona kuve nechokwadi chekuti maitiro avo e electroplating anoburitsa emhando yepamusoro, yakasimba, uye yakavimbika copper copper inosangana nezvinodiwa nevatengi vavo.
