Ukufakwa kwesinyithi yinkqubo esetyenziswa kakhulu kumashishini ahlukeneyo, kwaye ibandakanya ukusetyenziswa komaleko obhityileyo wesinyithi kwi-substrate ukukhulisa inkangeleko yayo, ukuphucula ukuxhathisa kwayo ekudlekeni, okanye ukunika ezinye izibonelelo zokusebenza.Inkqubo yokufakwa kwesinyithi idinga ukusetyenziswa kwesilungisi, eyona nto ibalulekileyo yesixhobo esilawula ukuhamba kombane ngexesha lenkqubo yokuqaba.Kweli nqaku, siza kuphonononga iintlobo ezahlukeneyo zokufakwa kwesinyithi kunye nendima yomlungisi kwinkqubo yokucwenga.
Iindidi zeMetal Plating
Electroplating
I-Electroplating lolona hlobo luxhaphakileyo lwesinyithi kwaye lubandakanya ukusetyenziswa kwamandla ombane ukufaka umaleko obhityileyo wesinyithi kwindawo eqhubayo.I-substrate eya kuhlanjululwa ifakwe kwisisombululo se-electrolyte esine-ion zetsimbi, kwaye i-rectifier isetyenziselwa ukulawula ukuhamba kwangoku kwi-plating bath.Iintsimbi eziqhelekileyo ezisetyenziswa kwi-electroplating ziquka i-nickel, ubhedu, i-chromium, kunye negolide.
I-Electroless Plating
Ngokungafaniyo ne-electroplating, i-electroless plating ayifuni ukusetyenziswa kwamandla ombane.Endaweni yoko, inkqubo yokucwenga ixhomekeke kwimpendulo yeekhemikhali ukufaka umaleko wesinyithi kwi-substrate.Le ndlela isoloko isetyenziselwa ukugquma izinto ezingezizo izinto ezifana neeplastiki kunye neeseramikhi.Ukufakwa kwe-Electroless plating kunika ubukhulu obufanayo bokugquma kwaye kunokusetyenziselwa ukucwenga uluhlu olubanzi lwesinyithi, kubandakanya nickel, ubhedu, kunye necobalt.
Ukuntywiliselwa Plating
I-immersion plating, eyaziwa ngokuba yi-autocatalytic plating, luhlobo lwentsimbi yentsimbi engadingi mthombo wamandla wangaphandle.Kule nkqubo, i-substrate igxininiswe kwisisombululo esinezinsimbi zetsimbi, kunye nee-agent zokunciphisa eziququzelela ukufakwa kwe-metal layer.Ukuntywiliselwa kokuntywiliselwa ngokuqhelekileyo kusetyenziselwa ukucola iindawo ezincinci, ezimile okwentsonkothileyo kwaye zifaneleke ngakumbi ukuphumeza ukwambathisa okufanayo kwimigangatho entsonkothileyo.
Ukufakwa kwebrashi
Ukucwenga kwebrashi yindlela ephathekayo neguquguqukayo yokwambatha ebandakanya ukusetyenziswa kwesifakeli esiphathwa ngesandla ukukhetha indawo ethile kwindawo ethile.Obu buchule buhlala busetyenziselwa ukulungiswa kwendawo, ukuchukumisa, okanye ukubeka iindawo ezinkulu ekunzima ukuzihambisa kwitanki yokucoca.Ukufakwa kwebhrashi kunokwenziwa kusetyenziswa iintlobo ngeentlobo zesinyithi, kubandakanywa nickel, ubhedu, kunye negolide.
Indima yoMlungisi kwiMetal Plating
Isilungisi silungu elibalulekileyo kwinkqubo yokufakwa kwesinyithi, njengoko ilawula ukuhamba kombane kwibhafu yokubeka.I-rectifier iguqula i-alternating current (AC) ukusuka kumthombo wamandla ukuya kwi-direct current (DC), efunekayo kwinkqubo ye-electroplating.Isilungisi kwakhona silawula i-voltage kunye ne-amperage ukuqinisekisa ukuba inkqubo yokucwenga iqhubeka ngesantya esifunwayo kwaye ivelise isambatho esifanayo.
Kwi-electroplating, isilungisi silawula ukubekwa kwee-ion zetsimbi kwi-substrate ngokulungelelanisa ukuxinana kwangoku kunye nobude benkqubo yokucwenga.Iintsimbi ezahlukeneyo zifuna iiparamitha zokucwenga ezikhethekileyo, kwaye isilungisi sivumela ulawulo oluchanekileyo kwezi ziguquguqukayo ukufezekisa ubungakanani obufunwayo beplating kunye nomgangatho.
Kwi-electroless plating kunye ne-immersion plating, isilungisi sinokungafuneki, njengoko ezi nkqubo zingathembeli kumbane wangaphandle.Nangona kunjalo, kwezinye iimeko, isilungisi sisenokusetyenziselwa ukulawula iinkqubo ezincedisayo ezinje ngokuphazamiseka okanye ukufudumeza isisombululo seplating.
Ukukhetha iRectifier eLungileyo yeMetal Plating
Xa ukhetha isilungisi sokufakwa kwesinyithi, izinto ezininzi kufuneka ziqwalaselwe ukuqinisekisa ukusebenza kakuhle komgangatho kunye nokusebenza kakuhle.Ezi zinto ziquka:
IiMfuno zangoku kunye neVolthage: Isilungisi kufuneka sibenakho ukuzisa amanqanaba akhoyo afunekayo akhoyo kunye nombane kwindawo yokuhlambela, ethathela ingqalelo ubungakanani beendawo ezityalwayo kunye neeparamitha zokucwenga.
Iimpawu zoLawulo kunye nokuBeka iliso: Isilungisi esilungileyo kufuneka sinikezele ngolawulo oluchanekileyo ngaphezulu kwangoku kunye nombane, kunye namandla okubeka iliso ukulandelela inkqubela phambili yenkqubo yokucoca kunye nokuqinisekisa umgangatho ongaguqukiyo.
Ukusebenza kunye nokuthembeka: Isilungisi kufuneka sisebenzise amandla kwaye sithembeke, sibe neempawu zokhuseleko ezakhelwe ngaphakathi ukukhusela ukugcwala, iisekethe ezimfutshane, kunye nezinye iingozi ezinokubakho.
Ukuhambelana neZisombululo zokuPlating: Isilungisi kufuneka sihambelane nezisombululo ezithile zokucoca kunye neenkqubo ezisetyenzisiweyo kwisicelo, kwaye kufuneka sakhiwe ngezinto ezichasene ne-corrosion kunye nokuvezwa kweekhemikhali.
Ukuqukumbela, ukucwenga kwesinyithi yinkqubo eguquguqukayo neyimfuneko kumashishini ahlukeneyo, kwaye ukhetho lohlobo oluchanekileyo lwendlela yokucwenga kunye nesilungisi esifanelekileyo kubalulekile ekufezekiseni umgangatho ophezulu, ukwambathisa okufanayo.Nokuba i-electroplating, i-electroless plating, i-immersion plating, okanye i-brush plating, indlela nganye ibonelela ngeenzuzo ezizodwa kwaye ifanele usetyenziso olwahlukileyo.Ngokuqondwa ngokufanelekileyo kweentlobo ezahlukeneyo zentsimbi kunye nendima yokulungiswa, abavelisi kunye neepleyiti banokwenza izigqibo ezinolwazi ukuhlangabezana neemfuno zabo zokugqoka kunye nokufezekisa umphezulu ofunwayo kunye neempawu zokusebenza.
