Kugwiritsa Ntchito Sodium Cyanide M'makampani a Electroplating

Electroplating ndi njira yofunika kwambiri pamakampani opanga zinthu, yomwe imaphatikizapo kuyika chitsulo chopyapyala pamwamba pa chitsulo chopangira zitsulo kudzera mu electrolysis. Izi sizimangowonjezera kukana kwa dzimbiri kwachitsulo komanso kumapangitsanso mawonekedwe ake okongola komanso mawonekedwe apamwamba. Sodium cyanide, mankhwala owopsa kwambiri koma osinthasintha, amathandizira kwambiri Pachikuz makampani.

Zoyambira za Electroplating

Electroplating imachokera pa mfundo ya electrolysis. Pakukhazikitsa kwa electroplating, chitsulo chopangira chitsulo chomwe chimayikidwa chimapangidwa ngati cathode, pomwe chitsulo chomwe chimayikidwa chimagwiritsidwa ntchito ngati anode. Zonse ziwiri za cathode ndi anode zimamizidwa mu njira ya electrolyte yomwe imakhala ndi ayoni achitsulo azitsulo zopangira. Mphamvu yamagetsi ikadutsa mu electrolyte, ma ion achitsulo mu yankho amakopeka ndi cathode (workpiece) ndipo amayikidwa pamwamba pake, ndikupanga wosanjikiza wopyapyala, wofanana wa zitsulo zopangira.

Udindo wa Sodium Cyanide mu Electroplating

Sodium cyanide (NaCN) amagwiritsidwa ntchito kwambiri mu electroplating ngati a Complexing Agent. Ili ndi mphamvu yopanga ma complexes okhazikika okhala ndi ayoni osiyanasiyana achitsulo. Pankhani ya electroplating, ma complexes achitsulo - cyanide ali ndi zabwino zingapo:

1. Ubwino Wokwera Wowonjezera: Zitsulo - cyanide zovuta zopangidwa ndi Sodium Cyanide kuthandizira kukwaniritsa yunifolomu komanso yosalala zitsulo zokhazikika pa workpiece pamwamba. Mwachitsanzo, mu electroplating yamkuwa, copper - cyanide complex imaonetsetsa kuti ayoni amkuwa amayikidwa mofanana, zomwe zimapangitsa kuti pakhale mkuwa wandiweyani komanso wotsatira. Izi ndizofunikira pamapulogalamu omwe kukhulupirika kwa gawo lopukutidwa ndikofunikira, monga mumakampani opanga zamagetsi pazolumikizira zomata.

2. Kufalikira Kwambiri: Kugwiritsa ntchito sodium cyanide mu njira electrolyte bwino kuponya mphamvu ya plating kusamba. Mphamvu yoponya imatanthawuza kuthekera kwa plating yankho kuyika chitsulo chosanjikiza chofananira pa chogwirira ntchito, ngakhale pazigawo zowoneka bwino zokhala ndi zotsalira ndi zotuluka. Maofesi achitsulo - cyanide amatha kufika bwino mbali zonse za workpiece, kuonetsetsa kuti atsekedwa kwathunthu. Izi ndizopindulitsa kwambiri m'mafakitale monga zamagalimoto, pomwe magawo omwe ali ndi mawonekedwe owoneka bwino amafunikira kupukutidwa kuti ateteze dzimbiri.

3. Bath Yokhazikika Yokwera: Sodium cyanide imathandizira kukhazikika kwa kusamba kwa electroplating. Imawongolera kuchuluka kwa ayoni achitsulo aulere mu yankho, kuteteza mapangidwe azitsulo zachitsulo zomwe sizili bwino - zotsatiridwa kapena zosakhala bwino. Popanga ma complexes okhazikika, amalola kuti pakhale njira yoyendetsedwa bwino komanso yosasinthika ya electroplating.

Kugwiritsa Ntchito Mwachindunji kwa Sodium Cyanide mu Electroplating

1. Copper Plating: Mu electroplating yamkuwa, Sodium cyanide amagwiritsidwa ntchito kupanga copper - cyanide complexes. Izi ndizofunikira makamaka pakuyika pazigawo monga zinc - alloy die - castings. Zinc - alloy die - castings amagwiritsidwa ntchito kwambiri popanga zinthu zokongoletsera, zipi, ndi tizigawo tating'ono tating'ono. Popeza zinki - alloy amatha kuwonongeka munjira za acidic plating, njira yopangira cyanide - copper - plating imagwiritsidwa ntchito ngati njira yoyambira. Mkuwa wosanjikiza waikamo ntchito cyanide - munali electrolyte amateteza nthaka - aloyi gawo lapansi ku malo acidic wa wotsatira plating njira, monga faifi tambala plating, komanso bwino adhesion wa wosanjikiza faifi tambala.

2. Silver Plating: Sodium cyanide amagwiritsidwanso ntchito mu electroplating siliva. Silver - cyanide complexes amapangidwa mu electrolyte, yomwe imapangitsa kuti siliva ikhale yosalala komanso yowala. Zinthu zokhala ndi siliva zimagwiritsidwa ntchito kwambiri m'makampani opanga zodzikongoletsera, kupanga zida zapa tebulo, ndi zolumikizira zamagetsi. Kugwiritsa ntchito sodium cyanide mu silver electroplating kumatsimikizira kutsirizika kwapamwamba, ndi siliva wosanjikiza wokhala ndi mawonekedwe abwino komanso kukana dzimbiri.

3. Zing'onoting'ono Zinc: Ngakhale kuyesayesa kwapangidwa kuti apange njira zopanda cyanide zinc - plating, nthawi zina, cyanide-based zinc electroplating imagwiritsidwabe ntchito. Zinc - cyanide complexes zopangidwa mothandizidwa ndi sodium cyanide zimapereka mphamvu zoponya bwino ndikulola kuyika kwa yunifolomu ya zinki. Zinc plating imagwiritsidwa ntchito kwambiri poteteza dzimbiri zazitsulo ndi chitsulo, monga m'mafakitale omanga ndi magalimoto.

Zilingaliro Za Chitetezo

Ngakhale kuti ali ndi ubwino wambiri pa electroplating, sodium cyanide ndi mankhwala oopsa kwambiri. Amatulutsa mpweya wa hydrogen cyanide akakumana ndi asidi kapena madzi. Chifukwa chake, njira zotetezera ziyenera kuchitika m'malo opangira ma electroplating omwe amagwiritsa ntchito sodium cyanide:

1. Kusamalira ndi Kusunga Moyenera: Sodium cyanide iyenera kusungidwa pamalo otetezeka, mpweya wabwino, kutali ndi zidulo ndi chinyezi. Ogwira ntchito yogwira sodium cyanide ayenera kuphunzitsidwa kagwiridwe koyenera, kuphatikizapo kugwiritsa ntchito zida zodzitetezera monga magolovesi, magalasi, ndi chitetezo cha kupuma.

2. Mapulani Oyankhira Mwadzidzidzi: Zomera zopangira ma electroplating zikuyenera kukhala ndi mapulani okwanira oyankha pakagwa ngozi kapena kutulutsa sodium cyanide. Ndondomekozi ziphatikizepo njira zotulutsira deralo, kuchepetsa mphamvu ya cyanide, ndi kupereka chithandizo chamankhwala kwa anthu omwe akhudzidwa.

3. Chitetezo cha chitetezo: Madzi otayira a electroplating omwe ali ndi sodium cyanide ayenera kusamalidwa bwino kuti achotse cyanide isanatulutsidwe ku chilengedwe. Njira zochizira zingaphatikizepo mankhwala oxidation, omwe amasintha cyanide kukhala mankhwala osavulaza kwambiri.

Pomaliza, sodium cyanide imagwira ntchito yofunika kwambiri pamakampani opanga ma electroplating, ndikupangitsa kuti pakhale zinthu zapamwamba kwambiri, zolimba, komanso zowoneka bwino. Komabe, kugwiritsidwa ntchito kwake kuyenera kuyang'aniridwa mosamala kuti atsimikizire chitetezo cha ogwira ntchito komanso chitetezo cha chilengedwe. Pamene ukadaulo ukupita patsogolo, zoyeserera zikupangidwa kuti apange njira zina, zopanda poizoni zopangira ma electroplating, koma pakadali pano, sodium cyanide ikadali chinthu chofunikira pakugwiritsa ntchito ma electroplating ambiri.
