Ziziphi izinto ezichaphazela ngokubanzi i-sodium cyanide copper plating?

Isodium cyanide Ukufakwa kobhedu sisiko I-Electroplating indlela esetyenziswa ngokubanzi kumashishini ahlukeneyo, ngakumbi kwi-electronics kunye nokuveliswa kwezacholo. Le nkqubo ibandakanya ukusetyenziswa kwe-a Isisombululo sePlating esebenza njenge-ejenti edibanisayo, ngokuyinhloko iqulunqwe ngeeyoni zobhedu kunye nesixa esithile I-cyanide yasimahla, zonke zigcinwe kwindawo ene-alkaline enamandla. Ngelixa le ndlela ingqineke iyasebenza, izinto ezininzi zinokuchaphazela kakhulu umgangatho wemveliso yokugqibela. Ukuqonda le miba kubalulekile ekuphuculeni inkqubo yokucwenga kunye nokuqinisekisa iziphumo ezikumgangatho ophezulu.

1. ulawulo Ubushushu

Enye yezona zinto zibalulekileyo ezichaphazelayo Isodium cyanide i-copper plating bubushushu besisombululo se-plating. Olona luhlu lweqondo lobushushu kule nkqubo ngokubanzi luphakathi kwama-50°C ukuya kuma-65°C. Ngaphakathi kolu luhlu, ukusebenza kakuhle kwangoku kwe-cathode kwandiswa, okukhokelela kwidiphozithi yobhedu efanayo kunye nomgangatho ophezulu.

Xa iqondo lobushushu liphantsi kakhulu, ukusebenza kakuhle kwangoku kwe-cathode kuyancipha, okukhokelela kumgangatho ombi wokutyabeka. Ngokwahlukileyo, amaqondo obushushu aphezulu kakhulu anokukhokelela ekubola kwesisombululo seplating, ukuvelisa izinto ezingafunekiyo ezifana ne-sodium carbonate kunye ne-ammonia. Ezi byproducts zinokuchaphazela kakubi inkqubo yokubekwa kunye nomgangatho wokugquma kokugqibela. Ke ngoko, ukugcina ubushushu obufanelekileyo kubalulekile ukuze kuphunyezwe iziphumo ezigqwesileyo zokucwenga.

2. Ulawulo loXinano lwangoku

Ukuxinana kwangoku yenye into ebalulekileyo ephembelela ukusebenza kakuhle kunye nomgangatho Isodium cyanide icwecwe lobhedu. Uxinaniso lwangoku lubhekisa kumyinge wombane osetyenziswayo kwindawo nganye yecathode. Ukwandisa ukuxinana kwangoku kunokukhokelela ekunciphiseni kokubili i-cathode kunye ne-anode esebenzayo ngoku.

Xa uxinano lwangoku lwe-anode luba phezulu kakhulu, lunokubangela ukugqithiswa kwe-anode, imeko apho i-anode iyancipha ukusebenza kwaye ithintele inkqubo yokucoca. Ukuthomalalisa lo mba, ukusetyenziswa konikezelo lwamandla okutshintsha ngamaxesha athile kunokuba luncedo. Ubuchwephesha buvumela ukonyuka okulawulwayo kuxinaniso lwangoku, okwenza kube lula ulawulo lwenkqubo yokucwenga kunye nokuphucula umgangatho wokugquma.

3. Indima ye-Cyclic Reversing Power Supply

Ukuphunyezwa kwe-cyclic ukubuyisela ukunikezelwa kwamandla kwinkqubo ye-electroplating inokunyusa kakhulu umgangatho we-copper coating. Le ndlela ivumela ukulungiswa kwe-anode density yangoku, enokukhokelela ekunciphiseni i-porosity yengubo. Isigqubuthelo esinemingxuma esincinci sithandeka ngokubanzi, njengoko sibonelela ngokhuseleko olungcono kwi-corrosion kwaye iphucula ukuqina kwayo yonke indawo.

Ukongeza, ukusetyenziswa konikezelo lwamandla okubuyisela umva ngebhayisikile kunokuphucula ukusebenza komgangatho wesisombululo seplating. Ngokongeza inani elincinci lesinyithi elikhanyayo kwisisombululo, kunokwenzeka ukuba ufezekise ubhedu oluqaqambileyo oluneempawu ezibalaseleyo zokulinganisa. Oku kudityaniswa kobuchule kunokubangela ukugqitywa komgangatho ophezulu ohlangabezana neemfuno ezingqongqo zezicelo ezahlukeneyo.

4. Ukungcola noLawulo Lwazo

Ubukho bokungcola kwisisombululo se-plating bunokuba nefuthe elibi kumgangatho wediphozithi yobhedu. Olunye ukungcola okuxhaphakileyo kufunyanwa kuyo sodium cyanide i-copper plating yi-carbonate. Ukuba i-carbonate content idlula i-70g / L, kubalulekile ukuyisusa ukuze kugcinwe ukunyaniseka kwenkqubo yokubeka.

Indlela eqhelekileyo yokususa i-carbonate engaphezulu ibandakanya ukupholisa isisombululo sokucoca ukuya ngaphantsi kwe-0 ° C, ukuvumela ukuba i-carbonate ikhanye ngokwemvelo. Nangona le ndlela ichanekileyo kwaye isebenzayo, kubalulekile ukuba uqaphele ukuba malunga ne-10% yetyuwa yensimbi inokulahleka ngexesha lenkqubo ye-crystallization. Ke ngoko, kufuneka kuqwalaselwe ngononophelo kulawulo lokungacoceki ukuqinisekisa ukuba isisombululo sokucwenga sihlala sisebenza kwaye umgangatho wemveliso yokugqibela awuphazamiseki.

isiphelo

I-sodium cyanide copper plating yindlela esetyenziswa ngokubanzi ye-electroplating ebonelela ngeenzuzo ezininzi malunga nokusebenza kakuhle kunye nomgangatho. Nangona kunjalo, impumelelo yale nkqubo ixhomekeke kakhulu kwizinto ezininzi ezibalulekileyo, eziquka ulawulo lobushushu, ulawulo lwangoku loxinaniso, ukusetyenziswa komjikelo wokubuyisela umva unikezelo lwamandla, kunye nolawulo lokungcola.

Ngokuqonda kunye nokuphucula ezi zinto, abavelisi banokuphucula umgangatho weengubo zabo zobhedu, baqinisekise ukuba bayahlangabezana neemfuno ezinzima zamashishini ahlukeneyo. Njengoko itekhnoloji iqhubela phambili, uphando oluqhubekayo kunye nophuhliso kwinkalo ye-electroplating iya kukhokelela kuphuculo olongezelelweyo kwinkqubo ye-sodium cyanide copper plating, ivula indlela yomgangatho ophezulu kunye neendlela zokuvelisa ezisebenzayo.

Isishwankathelo, ukulawulwa ngononophelo lobushushu, ukuxinana kwangoku, ubuchule bokubonelela ngombane, kunye namanqanaba okungcola kubalulekile ukuze kuphunyezwe iziphumo ezigqwesileyo kwi-sodium cyanide copper plating. Ngokugxininisa kule miba iphambili, abavelisi banokuqinisekisa ukuba iinkqubo zabo zokulinganisa i-electroplating zivelisa umgangatho ophezulu, oqinileyo, kunye neengubo zobhedu ezithembekileyo ezihlangabezana neemfuno zabathengi babo.
