Zinc alloy vinyo botolo kapu ndi mtundu wa kufa kuponyera ndi nthaka monga chigawo chachikulu.Pamwamba pake pali chowundana kwambiri pamwamba pa kufa, ndipo mkati mwake muli malo otseguka komanso chitsulo cha amphoteric.Choncho, pokha potengera njira yoyenera pretreatment ndi electroplating ndondomeko tingathe kuonetsetsa kuti electrodeposited ❖ kuyanika zinki aloyi vinyo botolo kapu ndi zomatira zabwino, poyerekeza ndi maonekedwe okongola a luso, ndipo amakwaniritsa zofunikira za oyenerera mankhwala.

Za4-1 amagwiritsidwa ntchito monga nthaka aloyi zakuthupi electroplating, ndi zigawo zake zazikulu ndi: Aluminiyamu 3.5% ~ 4.5%, mkuwa 0,75% ~ 1.25%, magnesium 0,03% ~ 0,08%, nthaka yotsalira, okwana zosafunika ≤ 0.2%.Aloyi ya zinki ya 925 ili ndi mkuwa wambiri ndipo ndiyosavuta kuyiyika ndi electrop.Nthawi zambiri, kachulukidwe wa aloyi ya zinki ndi 6.4 ~ 6.5 g / cm.Ngati kachulukidwe ndi osakwana 6.4 g/cm, matuza ndi pitting n'zosavuta kuchitika pambuyo electroplating.Mwachidule, kusankha kwa zipangizo kuyenera kuyendetsedwa mosamalitsa.Kuphatikiza apo, kufa koponyera kufa kumayenera kupangidwa momveka bwino kuti tipewe zovuta zosagonjetseka (monga pitting) ku electroplating.
