Plating aid de-ironing equipment
Time:2015-6-12 8:10:09
In hot-dip galvanizing production, a large amount of iron ion and acid are brought into the plating aid, which makes the content of iron ion
and the pH value in the plating rising. During galvanizing, the iron ions are taken into zinc pot to form zinc-iron particles, which not only severely influences the appearance of the plating pieces, but also leads to the increase of zinc consumption and galvanizing production
cost. “ZYHB-II type plating aid de-ferric salt equipment” can automatically and efficiently remove the iron ion in the plating aid to adjust the PH value; it reduces the generation of zinc dross during galvanizing, which both improves the surface quality of the plating piecesandreduces the zinc consumption. The de-ferric salt equipment can control the ferric salt concentration of the plating aid within 1g/l and effectively reduce the zinc consumption volume (total zinc saving volume: 15-30% of total zinc consumption; or 0.737% of each ton of work pieces).
