By using phosphate-free cleaners in plants of the hot-dip galvanizing industry, the process costs can be greatly optimized.
For this purpose, the products FAL Cl + FAL Cl / i pure were developed at Foster Chemicals
advantages:
- concentration and ratio between surfactant component (FAL Cl) and inhibitor component (FAL Cl / i pure) are variable and can be adjusted as required
- works already at room temperature
- very good cleaning properties
- nearly no sludge formation
- no rinsing necessary before the pickling step
- no problems with carrying over of the cleaner solution into the pickling bath
- phosphate free picking acid is much cheaper to dispose of
