Faʻaogaina o oloa

E i ai talosaga i electroplating ma electrolysis alamanuia, ma mafai foi ona faʻaaogaina e fai ai uaea.

Zinc sulfate heptahydrate o loʻo faʻaaogaina lautele i fofo galvanizing. I le taimi o le electroplating, o le sili sili aoga o metala paʻepaʻe heptahydrate fofo galvanizing o le i ai nei le lelei e oʻo i le maualuga e pei o le 100% ma o le teuina fua faatatau e vave. Lenei e le mafaatusalia e isi galvanizing faiga.

O le masani sulphate metala paʻepaʻe plating gaioiga e na talafeagai mo electroplating o paipa ma uaea ma faigofie geometric foliga ona o le leai o le lelei crystallization o le ufiufi ma le lelei faʻasalalauina gafatia ma loloto sopoia gafatia. I le metala paʻepaʻe sulphate electroplating gaioiga o metala paʻepaʻe uʻamea filogia, vagana ai mo le autu masima sima sulfate, isi mea ua lafoaʻia. O se talafeagai talafeagai o uʻamea masima ua faʻaopopoina i le fou faʻagasologa metotia e fai ai le uluaʻi uʻamea tasi ufiufi fausiaina o se metala paʻepaʻe uʻamea uʻamea ufiufi. O le toe faʻatulagaina o le gaioiga e le gata na ave ai i luma le lelei o le maualuga o loʻo i ai nei le lelei ma le vave teuina fua o le muamua gaioiga, ae na matua faʻaleleia atili foʻi le faʻasalalauina gafatia ma loloto plating agavaʻa. I taimi ua tuanaʻi, o vaega faigata e le mafai ona teuina, ae o lenei e faigofie ma faigata vaega mafai ona plated, ma le puipuiga faʻagaioiga O le 3 i le 5 taimi maualuga atu nai lo o le tasi uʻamea.

O le gaosiga o gaioiga ua faʻamaonia o le faʻaauau pea electrogalvanization o uaea ma paipa ma le metala paʻepaʻe sulfate o le a sili atu ona mama, susulu ma vave teuina fua nai lo le muamua ufiufi. Ia ausia le manaʻoga o le ufiufi mafiafia i totonu o 2 ~ 3min
