Kodi ndi zinthu ziti zomwe zimakhudza kwambiri sodium cyanide copper plating?

Sodium cyanide Copper plating ndichikhalidwe Pachikuz njira yomwe imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, makamaka pakupanga zamagetsi ndi zodzikongoletsera. Njirayi imaphatikizapo kugwiritsa ntchito a Plating njira zomwe zimagwira ntchito ngati zovuta, zomwe zimapangidwa ndi ayoni amkuwa ndi kuchuluka kwake Cyanide yaulere, zonse zimasungidwa m'malo amchere kwambiri. Ngakhale kuti njirayi yatsimikizira kuti ndi yothandiza, pali zinthu zingapo zomwe zingakhudze kwambiri ubwino wa mankhwala omaliza. Kumvetsetsa zinthu izi ndikofunikira kwambiri pakukhathamiritsa kwa plating ndikuwonetsetsa kuti zikuyenda bwino.

1. Kutentha Kutentha

Chimodzi mwazinthu zovuta kwambiri zomwe zimakhudza Sodium cyanide mkuwa plating ndi kutentha kwa plating njira. Kutentha koyenera kwa njirayi nthawi zambiri kumakhala pakati pa 50 ° C mpaka 65 ° C. Mkati mwa izi, cathode yamakono yamakono imachulukitsidwa, zomwe zimapangitsa kuti pakhale yunifolomu komanso mkuwa wapamwamba kwambiri.

Kutentha kukakhala kotsika kwambiri, mphamvu ya cathode panopa imachepa, zomwe zimapangitsa kuti plating ikhale yabwino. Mosiyana ndi zimenezi, kutentha kwambiri kungayambitse kuwonongeka kwa njira yothetsera plating, kupanga zinthu zosafunikira monga sodium carbonate ndi ammonia. Zopangira izi zitha kusokoneza plating ndi mtundu wa zokutira zomaliza. Choncho, kusunga kutentha koyenera n'kofunika kuti tipeze zotsatira zabwino kwambiri za plating.

2. Panopa Kachulukidwe Management

Kachulukidwe kakali pano ndi chinthu chinanso chofunikira chomwe chimakhudza magwiridwe antchito komanso mtundu wa Sodium Cyanide plating yamkuwa. Kachulukidwe kakali pano amatanthauza kuchuluka kwa magetsi omwe amagwiritsidwa ntchito pagawo lililonse la cathode. Kuchulukitsa kachulukidwe kakali pano kungayambitse kuchepa kwa ma cathode ndi anode pakali pano.

Kachulukidwe ka anode kakachulukirachulukira, zimatha kuyambitsa anode passivation, pomwe anode imakhala yochepa kwambiri ndikulepheretsa kupanga. Kuti muchepetse vutoli, kugwiritsa ntchito magetsi osinthira nthawi ndi nthawi kungakhale kopindulitsa. Njira imeneyi imalola kuwonjezereka kolamulirika kwa kachulukidwe kakali pano, kupangitsa kuti kasamalidwe kabwino ka plating ndi kuwongolera bwino zokutira.

3. Udindo wa Cyclic Reversing Power Supply

Kukhazikitsa kwamagetsi osinthira ma cyclic munjira yopangira ma electroplating kumatha kupititsa patsogolo kwambiri zokutira zamkuwa. Njirayi imalola kusintha kwa anode panopa, zomwe zingayambitse kuchepa kwa porosity ya zokutira. Chophimba chochepa kwambiri chimakhala chofunikira kwambiri, chifukwa chimapereka chitetezo chabwino ku dzimbiri komanso chimapangitsa kuti malo ophwanyika azikhala olimba.

Kuphatikiza apo, kugwiritsa ntchito magetsi osinthira ma cyclic kumatha kupititsa patsogolo magwiridwe antchito a plating. Powonjezera mchere wonyezimira wachitsulo pang'ono pa yankho, ndizotheka kukwaniritsa zokutira zamkuwa zowala ndi makhalidwe abwino kwambiri. Kuphatikizika kwa njirazi kungapangitse kumaliza kwapamwamba komwe kumakwaniritsa zofunikira zamagwiritsidwe osiyanasiyana.

4. Zodetsedwa ndi Kasamalidwe Kake

Kukhalapo kwa zonyansa muzitsulo zopangira plating kungakhale ndi zotsatira zovulaza pa khalidwe la mkuwa. Chimodzi mwazinthu zonyansa zomwe zimakumana nazo sodium cyanide copper plating ndi carbonate. Ngati mpweya wa carbonate uposa 70g/L, ndikofunikira kuti muchotse kuti musunge kukhulupirika kwa plating.

Njira yochotsera carbonate yochulukirapo imaphatikizapo kuziziritsa njira yoyatsira pansi pa 0 ° C, kulola kuti carbonate isungunuke mwachilengedwe. Ngakhale kuti njirayi ndi yolunjika komanso yothandiza, ndikofunika kuzindikira kuti pafupifupi 10% ya mchere wachitsulo ukhoza kutayika panthawi ya crystallization. Choncho, kuganizira mozama kuyenera kuperekedwa kwa kasamalidwe ka zonyansa kuti zitsimikizidwe kuti njira yopangira plating imakhalabe yogwira ntchito komanso kuti ubwino wa chinthu chomaliza sichisokonezedwa.

Kutsiliza

Sodium cyanide copper plating ndi njira yomwe imagwiritsidwa ntchito kwambiri ndi electroplating yomwe imapereka zabwino zambiri pakuchita bwino komanso mtundu wake. Komabe, kupambana kwa njirayi kumadalira kwambiri zinthu zingapo zofunika, kuphatikizapo kuwongolera kutentha, kasamalidwe kakachulukidwe kamakono, kugwiritsa ntchito mphamvu zosinthira mozungulira, komanso kusamalira zonyansa.

Pomvetsetsa ndi kukhathamiritsa zinthu izi, opanga amatha kupititsa patsogolo makulidwe awo amkuwa, ndikuwonetsetsa kuti akukwaniritsa zofunikira zamakampani osiyanasiyana. Pamene ukadaulo ukupitilirabe patsogolo, kafukufuku ndi chitukuko chomwe chikupitilira mu gawo la electroplating chitha kupititsa patsogolo kukonzanso kwa sodium cyanide copper plating process, kutsegulira njira yapamwamba kwambiri komanso njira zopangira zogwirira ntchito.

Mwachidule, kasamalidwe koyenera ka kutentha, kachulukidwe kamakono, njira zoperekera mphamvu zamagetsi, ndi milingo yonyansa ndizofunikira kuti tipeze zotsatira zabwino mu sodium cyanide copper plating. Poyang'ana pazifukwa zazikuluzikulu, opanga amatha kuonetsetsa kuti njira zawo zopangira ma electroplating zimatulutsa zokutira zamkuwa zapamwamba, zolimba, komanso zodalirika zomwe zimakwaniritsa zosowa za makasitomala awo.
