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;Isisombululo se-Electroplating esinamaqhekeza aqinileyo okanye ukungcola okugqithisileyo kwentsimbi yangaphandle, kuya kubangela iingxaki ezinjalo.Isisombululo: Ukuba umqulu omkhulu wocingo owenziwe ngesinyithi ukuya kokugquma ungentla urhabaxa, kusenokubakho amasuntswana aqinileyo kwisisombululo seplating.Ukuba uburhabaxa benxalenye bunzima, ukuxinana kwangoku kunokuba kuphezulu kakhulu.
Ukuba i-zinc i-coating ilungile, kodwa xa ukukhanya kuphuma kwi-3% ye-nitric acid, kukho isithunzi esimnyama kwi-coating, kwaye ifilimu inombala obomvu xa i-passivation isenzeka, enokuthi ibangelwa ukungcola kwentsimbi yangaphandle njengobhedu okanye i-lead. kulwelo olufakwe igalvanized.Xa kukho ingxaki kwinkqubo ye-galvanizing, khangela ubushushu kunye nokuxinana kwangoku kuqala, kwaye emva koko ulinganise kwaye ulungelelanise umxholo we-zinc kunye ne-sodium hydroxide kwindawo yokuhlambela ngokuhlalutya ukuhlamba.Ukuba amanqanaba e-DPE aphantsi angamiselwa ngovavanyo lweeseli ze-Hull.
Ukuba uburhalarhume bokugquma abubangelwa zezi zizathu zingasentla, kunokubangelwa ukungcola kwisisombululo sokutya.Ungathatha umthamo omncinci wesisombululo se-electroplating, emva kovavanyo lokuhluza, emva koko uthathe isisombululo esincinci se-electroplating, emva kovavanyo lonyango lwe-zinc powder, khangela ingxaki ibangelwa ngamasuntswana aqinileyo okanye ubhedu, ilothe kunye nezinye izinto ezingcolileyo zetsimbi zangaphandle.Zivavanye nganye nganye kwaye akunzima ukufumana unobangela wengxaki.Intsimbi ekhandisiweyo yokugquma igwebu, amandla okubopha akulunganga.
Ukuphathwa kakubi ngaphambi kwe-electroplating;Ubushushu bebhafu buphantsi kakhulu;Izongezo ezikumgangatho ophantsi okanye izongezo ezigqithisileyo kunye nokungacoceki kwezinto eziphilayo kunokubangela ukubambana kakubi.Umgangatho wesongezo nawo unempembelelo kwi-coating foaming.Ezinye izongezo ziphendula ngokungaphelelanga ngexesha lokudibanisa kwaye ziqhubeke nokwenza i-polymerize ngexesha lokugcinwa kwexesha elide okanye ukusetyenziswa.I-additive ivame ukuphazamisa i-lattice kunye nokudala uxinzelelo, kubangela ukuba iingubo zibe yi-blister.
Xa umqulu omkhulu galvanized ucingo galvanizing inkqubo ukutyabeka amagwebu, khangela kuqala ubushushu bath.Ukuba iqondo lokushisa lokuhlamba alikho phantsi, ngoko uqinise i-plating ngaphambi kokususa ioli, uthintele isinyithi se-matrix kwi-corrosion ye-asidi.Ukuba unika ingqalelo kwezi ngxaki, isenzeko esinamagwebu sisekho, kufuneka sinikele ingqalelo kwisixa kunye nomgangatho wezongezo, ngoko unokuyeka ukongeza izongezo, kunye ne-electrolysis ephezulu yangoku kangangexesha elithile, ukuze unciphise umxholo zongezo, jonga ukuba isenzeko esinamagwebu siyaphucuka.Ukuba akukho phuculo, kuyimfuneko ukujonga ukuba ixesha lokugcinwa kwezongezo lide kakhulu, okanye ukuba kukho ukungcola okuninzi kwizongezo.
