Zinc alloy wine fwj cap yog ib hom tuag casting nrog zinc ua lub ntsiab tivthaiv.Muaj ib txheej ntom ntom ntom ntom ntom saum npoo ntawm cov tuag casting, thiab sab hauv nws yog ib qho qhib cov qauv porous thiab cov hlau muaj khoom siv.Yog li ntawd, tsuas yog los ntawm kev siv cov txheej txheem pretreatment kom zoo thiab cov txheej txheem electroplating tuaj yeem ua kom ntseeg tau tias cov txheej txheem electrodeposited ntawm zinc alloy wine fwj cap muaj adhesion zoo, piv rau cov duab zoo nkauj, thiab ua tau raws li cov khoom tsim nyog.
Za4-1 feem ntau yog siv los ua zinc alloy khoom rau electroplating, thiab nws cov khoom tseem ceeb yog: Aluminium 3.5% ~ 4.5%, tooj liab 0.75% ~ 1.25%, magnesium 0.03% ~ 0.08%, zinc residual, tag nrho impurities ≤ 0.2%.925 qib zinc alloy muaj cov ntsiab lus tooj liab thiab yooj yim rau electroplated.Feem ntau, qhov ceev ntawm zinc alloy yog 6.4 ~ 6.5 g / cm2.Yog tias qhov ntom ntom tsawg dua 6.4 g / cm, blistering thiab pitting yog yooj yim tshwm sim tom qab electroplating.Nyob rau hauv luv luv, kev xaiv ntawm cov ntaub ntawv yuav tsum nruj me ntsis tswj.Tsis tas li ntawd, tuag-casting tuag yuav tsum tau tsim tsim nyog kom tsis txhob muaj qhov tsis xws luag (xws li pitting) rau electroplating.
