Kuthunyelwe ku 2018-08-091. Ungqimba ngalunye lwezinc ne-aluminium ku-aluminiyamu ye-zinc lusesimweni sokungenzi lutho , kuyilapho ungqimba oluwuthayela lunongqimba lwe-passivation luka-0.05~0.2μm kungqimba olungaphandle;
2. Amashidi e-zinc ne-aluminium ku-zinc aluminium enamathela adlala indima ephelele yokuvikelwa kwe-anode yomhlatshelo, kuyilapho ukumbozwa kwe-zinc kuzovela imfucumfucu ye-zinc ngemva kokuba ungqimba lwe-passivation lubhujisiwe.
3. Ingxenye ye-asidi ye-inorganic in the coating kanye ne-coating ingavikela i-matrix yensimbi ngesikhathi esifanayo lapho ivikela i-zinc ne-aluminium , kuyilapho i-zinc plating ingenzi.
4. I-zinc coating passivation layer ku-70 ~ 100 ℃ degrees centigrade, icrystallization yamanzi yaqala ukuhwamuka, okuholela ekuqhekekeni kongqimba lwe-passivation, kuthinte ukumelana nokugqwala kwe-zinc enamathela, kanye ne-zinc aluminium enamathela kuma-degrees angu-260 noma izinga lokushisa eliphakeme le-sintering, ngakho-ke. esimeni esinjalo.
