F-I nano conversion coating process
Details
What is the difference between FI nano conversion coating process and traditional pretreatment process?
Bath Order:
Stainless Steel Tank
Alkaline wash - the only step that requires heat
It is better to have DI-wash before F-1
F-1 Nano Conversion Coating Conversion Coating Treatment (≥20 seconds)
It is better to have DI-wash after F-1
Optional: Dry after F-1
Powder coating, paint, CED/AED
Conversion Coating Process:
Process - Reaction Mechanism
Process - Thick Film - Forming and Control
Slot and Control:
Matching Tank: deionized water + FI nano conversion coating
Adjust the PH-value between 3.8-4.5
Production:
Control PH-value (3.8-5.5)
Add FI nano conversion coating
Detection of Zr-concentration
Tank solution life: no limit (no limit on tank changing time)
Other points of attention: detection of washing water (conductivity)
Process - Automatic Control with Shinechem Au-100 System
