Aluminum Surface Cleaner
- Aluminum surface cleaning is essential in preparing aluminum for powder coating or other finishing processes, as it ensures optimal adhesion and a smooth, durable finish. Here are some commonly used aluminum surface cleaners:
1. Alkaline Cleaners
- Purpose: Removes oils, greases, and organic contaminants.
- Chemicals: Sodium hydroxide, potassium hydroxide, silicates, phosphates, and surfactants.
- Process: Alkaline cleaners effectively strip oils and other contaminants by saponifying fats and emulsifying oils, followed by a water rinse.
2. Acid Cleaners (Deoxidizers)
- Purpose: Removes oxides, rust, scale, and other inorganic contaminants.
- Chemicals: Phosphoric acid, nitric acid, sulfuric acid, and hydrofluoric acid in specific cases.
- Process: Acid cleaning or deoxidizing involves dipping the aluminum in an acid solution to strip off oxides and create a clean surface. This process is usually followed by a thorough rinse to prevent acid residues.
