Kungani I-Cyanide Kunzima Ukuyishintsha Embonini Ye-Electroplating?

The I-Electroplating imboni kudala ithembele kuyo I-Cyanideizixazululo ezisekelwe, naphezu kwemizamo yokuthola ezinye izindlela, i-cyanide ihlala iyisisekelo ezinqubweni eziningi ze-electroplating. Lesi sihloko sibheka izizathu zokuthi kungani i-cyanide kunzima ukuyishintsha embonini ye-electroplating.

Izisekelo ze-Electroplating

I-Electroplating iyinqubo ehilela ukufaka ungqimba oluncane lwensimbi ku-substrate ngokudlulisela amandla kagesi ngesisombululo se-electrolyte esiqukethe ama-ion ensimbi. Ama-ion ensimbi esixazululweni akhangwa ku-substrate ekhokhiswa kabi (i-cathode), lapho ethola khona ama-electron futhi afakwe njengensimbi eqinile.

Iqhaza le-Cyanide ku-Electroplating

I-Cyanide compounds, njenge I-sodium cyanide kanye ne-potassium cyanide, ivame ukusetshenziswa ezindaweni zokugeza ze-electroplating ngezizathu ezimbalwa ezibalulekile:

Ikhono Eliyinkimbinkimbi Eliyingqayizivele

Amayoni e-cyanide (CN⁻) anekhono elimangalisayo lokwenza izakhiwo ezizinzile ngama-ion ensimbi. Ekulawulweni kwe-electroplating, lesi sakhiwo sifiseleka kakhulu njengoba sivumela ukulawula okunembayo kokuhlangana kwama-ion ensimbi amahhala ku-electrolyte. Ngokwenza izingxube ze-metal-cyanide, ukutholakala kwama-ion ensimbi amahhala kuyancishiswa, okubuye kubambezele izinga lokumiswa kwensimbi ku-substrate. Lokhu kufakwa okulawulwayo kubangela ukufana kwensimbi okufana nokunamathelayo.

Isibonelo, lapho i-electroplating silver, ukwakheka kwe-silver-cyanide complex (Ag(CN)₂⁻) kuzinza kakhulu ama-ion esiliva esixazululweni. Lokhu kuzinza kuvimbela ukubekwa kwesiliva okusheshayo nokungalawuleki, okungase kuholele ekufakweni kwekhwalithi embi, okungalingani. Ukuzinza okuphezulu okungaguquguquki kwe-silver-cyanide complex kuqinisekisa ukuthi ama-ion esiliva akhululwa kancane futhi kancane phakathi nenqubo ye-electroplating, okuvumela ukufakwa okubushelelezi nokungaguquguquki ku-cathode.

Ikhwalithi Yokuhlanganisa Ethuthukisiwe

Ukusetshenziswa kwe-cyanide ekugezeni kwe-electroplating ngokuvamile kuholela ekwakhiweni kwezingubo ezinezici zekhwalithi ephakeme. Ukufakwa kancane kancane nokulawulwayo okwenziwa ama-cyanide complexes kubangela ukujiya okuminyene kakhulu, okubushelelezi, futhi okunamathela kangcono ku-substrate. Lezi zimbotshana zibonisa ukumelana nokugqwala okuthuthukisiwe, ukumelana nokugqokwa, kanye nokukhanga kobuhle uma kuqhathaniswa nalezo ezitholakala kusetshenziswa ezinye izindlela zokucwenga.

Endabeni yokucwecwa kwegolide, ama-electrolyte asekelwe ku-cyanide anika amandla ukubekwa kongqimba oluncane lwegolide olunamathela ngokuqinile ensimbi engaphansi. Lokhu kubalulekile ezinhlelweni ezifana nokwenza ubucwebe nezinto zikagesi, lapho ikhwalithi ephezulu, ehlala isikhathi eside inamathela igolide ibalulekile. Ukusetshenziswa kwe-cyanide kuvumela ukwakhiwa kwezingubo ezingabonakali kuphela kodwa futhi ezisebenza kakhulu, ezihlangabezana nezidingo eziqinile zalezi zimboni.

Ukusebenza Okubanzi

Izinqubo ze-Cyanide-based electroplating zihlukahlukene futhi zingasetshenziswa ezinhlobonhlobo zezinsimbi nama-substrates. Zisebenza kahle kakhulu ekunamathiseleni izinsimbi okunzima ukuzifaka kusetshenziswa ezinye izindlela, njengegolide, isiliva, ithusi, nezinc. Ikhono le-cyanide ukwenza ama-complexes azinzile ngalezi zinsimbi lenza kube inketho ekahle yokuzuza ukumbozwa kwekhwalithi ephezulu ekusetshenzisweni kwezimboni ezihlukahlukene.

Kungakhathaliseki ukuthi ihlanganisa izingxenye ze-elekthronikhi ezithambile noma izingxenye ezinkulu zezimboni, i-cyanide-based electroplating ibonakale iyindlela ethembekile nephumelelayo. Inqubo ingalungiswa ukuze ihlangabezane nezidingo ezithile zama-substrates ahlukene kanye nezinhlelo zokusebenza, okwenza kube ukukhetha okuncanyelwayo kubakhiqizi abaningi.

Izinselelo Ekushintsheni I-Cyanide

Naphezu kobuthi obaziwayo be-cyanide, imizamo yokuthuthukisa ezinye izindlela ezisebenzayo iye yabhekana nezinselele ezinkulu:

Igebe Lokusebenza

Kuphakanyiswe amakhemistri amaningi okucwenga ahlukile, kodwa ambalwa akwazile ukufanisa ukusebenza kwezinhlelo ezisekelwe ku-cyanide ngokwekhwalithi yokumboza, ukulawulwa kwezinga lokubeka, kanye nokuhlukahluka. Ezinye izindlela ezingezona i-cyanide zivame ukulwa nokufinyelela izinga elifanayo lokufana, ukunamathela, nokumelana nokugqwala njengezingubo ezisekelwe ku-cyanide.

Isibonelo, ezinye izinqubo zokucwenga isiliva okungeyona i-cyanide zingase zibangele ukumboza okunezimbotshana ezimbotshana kakhulu futhi ezingabambeleli kangako, okuzenze zibe lula ekugqwaleni nasekuguge. Le mikhawulo yokusebenza ingaba yisiphazamiso esikhulu ezinhlelweni zokusebenza lapho ubuqotho nokuqina kwe-coating kubalulekile.

Ukucatshangelwa Kwezindleko

Ukuthuthukisa nokusebenzisa ubuchwepheshe obusha be-non-cyanide electroplating kungabiza. Izindleko zocwaningo nentuthuko, kanye nesidingo sokushintsha imishini yokucwenga ekhona kanye nezinqubo, kungaba isithiyo esibalulekile ekwamukelweni kwezinkampani eziningi ze-electroplating. Kwezinye izimo, izindleko zamanye amakhemikhali nazo zingase zibe phezulu kune-cyanide, okungezelele ezinseleleni zomnotho.

Amabhizinisi amancane naphakathi nendawo, ikakhulukazi, angase akuthole kunzima ukuthethelela ukutshalwa kwezimali okudingekayo ukuze ashintshele ezindleleni zokucwenga ezingezona ze-cyanide. Imithelela yezezimali yalolo shintsho ingaba yisithiyo, ikakhulukazi emakethe encintisanayo lapho ukulawulwa kwezindleko kubalulekile.

Ukuhambisana Kwenqubo

Ukushintshela ku-non-cyanide electroplating kungase kudinge izinguquko eziphawulekayo ezinqubweni zokukhiqiza ezikhona, okuhlanganisa ukulungiswa kokwakheka kokugeza okucwebezelayo, izimo zokusebenza, nezindlela zokwelashwa kwemfucuza. Ukuqinisekisa ukuhambisana nemishini yamanje kanye nemigqa yokukhiqiza kungaba umsebenzi oyinkimbinkimbi futhi odla isikhathi, futhi noma yikuphi ukuphazamiseka kwenqubo yokukhiqiza kungaholela ekulahlekelweni kokukhiqiza kanye nezindleko ezikhulayo.

Ngaphezu kwalokho, udoti okhiqizwa ezinqubweni ze-non-cyanide electroplating ungase ube nezici ezihlukile kunalezo ezivela ezinqubweni ezisekelwe ku-cyanide, ezidinga ukuthuthukiswa kokwelashwa kwemfucuza kanye namasu okulahla. Lokhu kwengeza esinye isendlalelo sobunzima enqubweni yoguquko.

Isiphetho

Sengiphetha, nakuba ubuthi be-cyanide bugqugquzele ukufuna ezinye izindlela zokufaka i-electroplating, izici zayo eziyingqayizivele kanye nezinzuzo zokusebenza kwenze kwaba nzima kakhulu ukushintshwa embonini ye-electroplating. Ikhono le-cyanide ukwenza izingxube zensimbi ezizinzile, lithuthukise ikhwalithi yokunamathela, futhi lisetshenziswe ezinhlobonhlobo eziningi zezinsimbi nama-substrates liyaqhubeka liyenza ingxenye ebaluleke kakhulu ekusebenzeni okuningi kwe-electroplating.

Kodwa-ke, ukuzibophezela kwemboni ekusimamiseni imvelo kanye nokuphepha kwabasebenzi kusho ukuthi ukufuna ezinye izindlela ezisebenzayo ezingezona i-cyanide ngokungangabazeki kuzoqhubeka. Njengoba intuthuko yobuchwepheshe kanye namakhemikhali amasha kuthuthukiswa, kunethemba lokuthi ngolunye usuku kuzotholakala ukushintshwa okuphumelelayo ngempela nokuncintisana kwezindleko ze-cyanide ekufakweni kwe-electroplating. Kuze kube yileso sikhathi, imboni ye-electroplating izodinga ukuphatha ngokucophelela ukusetshenziswa kwe-cyanide, isebenzise izinyathelo eziqinile zokuphepha kanye nokuphathwa kwemfucuza okufanele ukuze kuncishiswe umthelela wayo empilweni yabantu kanye nemvelo.
