I-galvanized wire coating rough, passivation film ayiqaqambi, ubushushu bebhafu buphezulu kakhulu.Ukuba ubuninzi be-cathode yangoku buphezulu kakhulu, umxholo we-zinc kwindawo yokuhlambela uphezulu kakhulu okanye i-sodium hydroxide kunye nomxholo we-DPE uphantsi kakhulu;Iingqungquthela eziqinileyo okanye ukungcola okugqithisileyo kwentsimbi yangaphandle kwisisombululo se-electroplating kunokubangela iingxaki ezinjalo.Isixazululo: Ukuba ukutyabeka enkuluucingo lwezinkiirhabaxa, kusenokubakho amasuntswana aqinileyo kwisisombululo seplating.Ukuba uburhabaxa benxalenye bunzima, ukuxinana kwangoku kunokuba kuphezulu kakhulu.
Ukuba i-zinc yokugquma ilungile, kodwa kwi-3% ye-nitric acid xa ukukhanya, i-coating inomthunzi omnyama, i-passivation iyenzeka xa ifilimu ibomvu, inokubangelwa ukungcola kwentsimbi yangaphandle njengobhedu okanye i-lead kwi-galvanizing liquid.Xa iingxaki zivela kwinkqubo ye-galvanizing coil enkuluucingo lwezinki, iqondo lokushisa kunye nokuxinana kwangoku kuhlolwa kuqala, kwaye emva koko umxholo we-zinc kunye ne-sodium hydroxide kwisisombululo se-plating ulinganiswa kwaye ulungelelaniswe ngokuhlalutya kwesisombululo se-plating.Ukuba ngaba umxholo we-DPE uphantsi unokumiselwa ngovavanyo lweeseli ze-hull.
Ukuba uburhalarhume bokugquma abubangelwa zezi zizathu zingasentla, kunokubangelwa ukungcola kwisisombululo sokutya.Ungathatha umthamo omncinci wesisombululo se-electroplating, uvavanyo lokucoca, kwaye emva koko uthathe isisombululo esincinci se-electroplating, kunye nonyango lwe-zinc powder emva kovavanyo, khangela ingxaki ngamasuntswana aqinileyo okanye ubhedu, ilothe kunye nezinye izinto ezingcolileyo zesinyithi zangaphandle ezibangelwa.Enye nenye, akunzima ukufumana unobangela wengxaki.ucingo lwentsimbii-blister yokugquma, ukunamathela kakubi.
Ukuphathwa kakubi ngaphambi kokutyalwa;Ubushushu bebhafu buphantsi kakhulu;Umgangatho ophantsi wezongezo okanye izongezo ezininzi kakhulu kunye nokungcola kwe-organic kuya kubangela ukubambana okungalunganga.Umgangatho wezongezo nawo unempembelelo kwi-coating foaming.Ezinye izongezo ziphendula ngokungaphelelanga ngexesha lokudibanisa kwaye ziqhubeke nokwenza i-polymerize ngexesha lokugcinwa kwexesha elide okanye ukusetyenziswa.I-additive ithande ukuphazamisa i-crystal lattice kwaye ibangele uxinzelelo, ibangela ukuba i-coating iqhume.
Xa ukutyabeka enkuluucingo lwezinkii-blistered kwinkqubo yokufaka i-galvanizing, ubushushu bokuhlamba kufuneka buhlolwe kuqala.Ukuba ubushushu bokuhlamba abukho phantsi, kwaye ngoko ukomeleza ukususwa kweoli ngaphambi kokutyalwa, ukukhusela isiseko sesinyithi kwi-corrosion ye-asidi.Ukuba unika ingqalelo kwezi ngxaki, i-bubbling phenomenon isekhona, kufuneka inikele ingqalelo kwithamo kunye nomgangatho wezongezo, ngoko unokuyeka ukongeza izongezo, kunye ne-electrolysis ephezulu yangoku kangangexesha elithile, ukunciphisa umxholo wezongezo, jonga ukuba isenzeko sokuqhwanyaza siphuculwe.Ukuba akukho phuculo, khangela ukuba i-additive igcinwe ixesha elide okanye ingaba iqulethe ukungcola okuninzi.
