Our company uses an in-house mixed Non-chromated De-oxidizer. The percentages are fairly simple but duplicating the formula for the initial charge is posing a problem. The person who created the mix in the first place has retired and left for places unknown.
It is:
H2SO4 5-10%
HNO3 5-10%
FeSO4 15-25%
The trick is to match the total acid to the total ferrous at around 10%-20% any one have an idea on the quantities required to make up a 2000 gallon bath?
8 gal H2SO4
8 gal HNO3
20 lbs FeSO4
seems to be the suggested amounts.
