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. # Aluminum Cleaner Manufacturer.
