Qhov sib txawv ntawm qhov txias thiab kub dip galvanizing.
Thawj qhov sib txawv ntawm cov txheej txheem yog: kub-dip galvanizing yog cov txheej txheem ua tiav yog degreased, pickled, impregnated, qhuav thiab tom qab ntawd ntxiv rau molten zinc tov, txias galvanized qhov chaw feem ntau yog raus hauv molten zinc thiab yog li ib txoj hauv kev tau txais cov hlau. txheej. Lub hauv paus ntsiab lus tseem ceeb yog kub-dip galvanized kev pab them nqi muaj peev xwm, lub txheej kuj yog ntau ntom, tsis muaj organic inclusions. Peb txhua tus paub tias cov txheej txheem ntawm zinc tsis kam rau atmospheric corrosion muaj kev tiv thaiv txhua yam nrog rau kev tiv thaiv electrochemical. Hauv qee qhov chaw corrosive, qhov saum npoo ntawm zinc txheej feem ntau yog ZnO, Zn thiab alkaline zinc carbonate txheej ntawm cov yeeb yaj kiab tiv thaiv, uas ua rau qee yam ua rau qeeb cov corrosive ntawm zinc, cov yeeb yaj kiab tiv thaiv no raug rhuav tshem tom qab tsim ib qho tshiab. zaj duab xis. Thaum cov zinc txheej raug mob hnyav thiab cov hlau matrix raug hem, txias galvanizing tseem hu ua electro-galvanizing. Kev siv lub ntsiab ntawm cov khoom siv electrolytic degrease thiab pickle lub workpiece mus rau hauv ib qho kev daws teeb meem uas muaj zinc ntsev, thiab tom qab ntawd txuas nrog qhov tsis zoo electrode ntawm cov khoom siv electrolytic; zinc phaj yog muab tso rau ntawm lub workpiece, txuas nrog lub zoo electrode ntawm cov khoom siv electrolytic, txuas nrog lub hwj chim mov, thiab ib txheej ntawm zinc yog tso rau ntawm lub workpiece.
Yuav ua li cas kom paub qhov txawv ntawm txias galvanized thiab pre-kub-dip galvanized?
Qhov txawv ntawm cov khoom siv galvanized: kub-dip galvanized tsos tsis zoo li muag heev thiab ci li txias galvanized, tab sis lub thickness ntawm zinc txheej yog kaum ob lub sij hawm ntawm txias galvanized. Anti-corrosion zog yog electro-galvanized zinc txheej yog thicker, saum npoo ntawm plating feem ntau pom ntawm qhov muag liab qab tuaj yeem pom tau tias ci flakes, qhov saum npoo tuaj yeem kov ntawm tes. Xav txog qee qhov kev ntxhib los mos, qhov tsos ntawm cov xim nyiaj ci. Kub-dip galvanizing ntau lawm kub yog siab dhau lawm, cov tsos yog feem ntau grey, khob yuav ua rau zinc-hlau alloy txheej ntawm cov me me tshwm sim poob.
Txias galvanized dav dav yog smoother, silver grey, tsis muaj sequins.
