Ukusetyenziswa kweSodium Cyanide kuShishino lwe-Electroplating

I-Electroplating yinkqubo ebalulekileyo kwishishini lemveliso, ebandakanya ukubeka umaleko obhityileyo wesinyithi kumphezulu wentsimbi yokusebenza nge-electrolysis. Le nkqubo ayiphuculi kuphela ukuxhathisa kwentsimbi kodwa iphucula inkangeleko yayo yobuhle kunye nomgangatho womphezulu. Isodium i-cyanide, ikhompawundi yekhemikhali eyityhefu kakhulu kodwa esebenza ngeendlela ezininzi, idlala indima ebalulekileyo kwi I-Electroplating shishini.

Iziseko ze-Electroplating

I-Electroplating isekelwe kumgaqo we-electrolysis. Kwi-electroplating setup, i-workpiece yensimbi eya kugqitywa yenziwe i-cathode, ngelixa isinyithi esiza kufakwa sisetyenziswe njenge-anode. Zombini i-cathode kunye ne-anode zintywiliselwa kwisisombululo se-electrolyte esiqulethe ii-ion zetsimbi zesinyithi. Xa umbane wombane ugqithiswa kwi-electrolyte, i-ion zetsimbi kwisisombululo zikhangwa kwi-cathode (i-workpiece) kwaye ifakwe kumphezulu wayo, yenze umgca omncinci, ofanayo wesinyithi.

Indima yeSodium Cyanide kwi-Electroplating

I-sodium cyanide (NaCN) isetyenziswa ngokubanzi kwi-electroplating njenge Iarhente entsonkothileyo. Inamandla okwenza ii-complexes ezizinzileyo kunye ne-ion ezahlukeneyo zetsimbi. Kumxholo we-electroplating, ezi zixhobo zetsimbi-cyanide zineenzuzo ezininzi:

1. Umgangatho Wokubawa oPhuhliweyo: Isinyithi - i-cyanide complexes eyenziwe yi Isodium cyanide uncedo ekufezekiseni ideposition ngaphezulu iyunifomu kwaye agudileyo metal kumphezulu workpiece. Ngokomzekelo, kwi-electroplating yethusi, i-copper - cyanide complex iqinisekisa ukuba i-ion zethusi zifakwe ngokulinganayo, okubangelwa ubhedu oluqinileyo kunye oluhambelanayo. Oku kubalulekile kwizicelo apho imfezeko yomaleko ocekethekileyo iyimfuneko, njengakwishishini le-elektroniki lokudibanisa izihlanganisi.

2. UFundo oluphuculweyo: Ukusetyenziswa kwe sodium cyanide kwisisombululo se-electrolyte siphucula amandla okuphosa kwindawo yokuhlambela. Amandla okuphosa abhekiselele kwisakhono sesisombululo sokufaka idiphozithi yomaleko ofanayo wesinyithi kwindawo yokusebenza, nakwiziqendu ezintsonkothileyo ezinemiphunga kunye neeprotrusions. I-metal - i-cyanide complexes inokufikelela ngokufanelekileyo kuzo zonke iindawo ze-workpiece, iqinisekisa ukugubungela ngokupheleleyo. Oku kuluncedo kakhulu kumashishini afana neemoto, apho iindawo ezinejiyometri entsonkothileyo kufuneka zifakwe ipleyiti ukuze kukhuselwe umhlwa.

3. Ukuhlambela okuzinzile: I-sodium cyanide inceda ekugcineni ukuzinza kwebhafu ye-electroplating. Ilawula ukuxinwa kwee-ion zetsimbi zamahhala kwisisombululo, ukuthintela ukubunjwa kweediphozithi zetsimbi ezingahambelani kakuhle okanye ezikumgangatho ophantsi. Ngokwenza ii-complexes ezizinzileyo, ivumela inkqubo elawulwayo kunye ne-electroplating eqhubekayo.

Ukusetyenziswa ngokuthe ngqo kweSodium Cyanide kwi-Electroplating

1. Ukucwenga ubhedu: Kwi-electroplating yobhedu, Isodium cyanide isetyenziselwa ukwenza i-copper - cyanide complexes. Oku kubaluleke ngakumbi xa utyabeka kwii-substrates ezifana ne-zinc-alloy die-castings. I-Zinc - i-alloy die - i-castings isetyenziswa ngokubanzi ekwenzeni izinto zokuhombisa, ii-zippers, kunye neendawo ezincinci zoomatshini. Ekubeni i-zinc-alloy ichaphazeleka kukuhlwa kwizisombululo ze-acidic plating, inkqubo ye-cyanide esekwe kwi-copper-plating isoloko isetyenziswa njengenyathelo lokuqala lokutyabeka. Umaleko wobhedu ofakwe kusetyenziswa i-cyanide - equlethe i-electrolyte ikhusela i-zinc - i-alloy substrate ukusuka kwindawo ene-acidic yeenkqubo ze-plating ezilandelayo, ezifana ne-nickel plating, kwaye iphucula ukunamathela kwe-nickel layer.

2. Ukucwenga kweSilivere: I-sodium cyanide ikwasetyenziswa kwi-electroplating yesilivere. I-Silver-cyanide complexes yenziwe kwi-electrolyte, eyenza i-deposition yesilivere egudileyo kwaye eqaqambileyo. Izinto zesilivere-ezifakwe kwi-platet zidla ngokusetyenziswa kwishishini lezacholo, ukwenza i-tableware, kunye noqhagamshelwano lombane. Ukusetyenziswa kwe-sodium cyanide kwi-electroplating yesilivere kuqinisekisa ukugqitywa komgangatho ophezulu, kunye nomaleko wesilivere unokubonakala okugqwesileyo kunye nokuxhathisa umhlwa.

3. Ukubalwa kweZinc: Nangona iinzame zenziwe ukuphuhlisa i-non-cyanide zinc - iinkqubo ze-plating, kwezinye iimeko, i-cyanide-based based zinc electroplating isasetyenziswa. I-zinc - i-cyanide complexes eyenziwe ngoncedo lwe-sodium cyanide inika amandla amahle okuphosa kwaye ivumela ukubekwa kwe-zinc layer efanayo. I-Zinc plating isetyenziselwa ngokubanzi ukukhusela i-corrosion yensimbi kunye nentsimbi, njengakumashishini okwakha kunye neemoto.

Iingqwalaselo zoKhuseleko

Ngaphandle kweenzuzo ezininzi kwi-electroplating, i-sodium cyanide yinto enetyhefu kakhulu. Ikhupha igesi yehydrogen cyanide xa idibana neeasidi okanye amanzi. Ke ngoko, amanyathelo angqongqo okhuseleko kufuneka abe kwindawo yezixhobo ze-electroplating ezisebenzisa i-sodium cyanide:

1. Ukuphatha ngokufanelekileyo kunye noGcino: I-sodium cyanide kufuneka igcinwe kwindawo ekhuselekileyo, indawo engenamoya, kude ne-acids kunye nokufuma. Abasebenzi abaphatha i-sodium cyanide kufuneka baqeqeshwe kwiinkqubo ezifanelekileyo zokuphatha, kubandakanywa nokusetyenziswa kwezixhobo zokukhusela zomntu ezifana neeglavu, izibuko kunye nokukhusela ukuphefumla.

2. IziCwangciso zokuPhendula ngokuNgxamisekileyo: Izityalo ze-Electroplating kufuneka zibe nezicwangciso ezibanzi zokusabela kwimeko yonxunguphalo kwimeko yokuchitheka ngengozi okanye ukukhutshwa kwe-sodium cyanide. Ezi zicwangciso kufuneka zibandakanye iinkqubo zokukhupha indawo, ukungathathi hlangothi kwe-cyanide, kunye nokubonelela ngoncedo lwezonyango kubasebenzi abachaphazelekayo.

3. Ukukhuselwa kwendalo: Amanzi amdaka avela kwiinkqubo ze-electroplating eziqulethe i-sodium cyanide kufuneka aphathwe ngokufanelekileyo ukususa i-cyanide ngaphambi kokuba ikhutshwe kwindawo. Iindlela zonyango zinokubandakanya i-chemical oxidation, eguqula i-cyanide kwiikhompawundi ezingenabungozi.

Ukuqukumbela, i-sodium cyanide idlala indima ebalulekileyo kwishishini le-electroplating, livumela ukuveliswa komgangatho ophezulu, ozinzileyo, kunye neemveliso ezicwecwe ezithandekayo. Nangona kunjalo, ukusetyenziswa kwayo kufuneka kulawulwe ngononophelo ukuqinisekisa ukhuseleko lwabasebenzi kunye nokukhuselwa kwendalo. Njengoko iteknoloji iqhubela phambili, kwenziwa iinzame zokuphuhlisa enye, iinkqubo ezingenatyhefu ye-electroplating, kodwa okwangoku, i-sodium cyanide ihlala iyinxalenye ebalulekileyo kwizicelo ezininzi ze-electroplating.
