- Ingredients:
- Strong Alkalis: Such as sodium hydroxide or potassium hydroxide. They react with grease to break it down chemically, providing powerful degreasing capabilities.
- Surfactants: Anionic surfactants like sodium lauryl sulfate are often included. They help emulsify the loosened grease and make it easier to rinse away.
- Solvents: Organic solvents like trichloroethylene or methylene chloride (in some formulations, with strict safety controls due to their toxicity). These solvents can dissolve oils and fats that are difficult to remove by other means.
- Chelating Agents: For example, ethylenediaminetetraacetic acid (EDTA). They bind to metal ions in the water, preventing them from depositing back onto the metal surface and causing staining or corrosion.
- Efficacy:
- Deep Degreasing: Thoroughly eliminates heavy grease, lubricants, and machining oils that adhere to metal surfaces, ensuring a clean base for further processing like painting or welding.
- Rust Prevention: Some formulations contain inhibitors that protect the metal from rust formation during and after the cleaning process, especially important for ferrous metals.
- Surface Preparation: Creates a smooth and clean surface, improving the adhesion of coatings or finishes applied later.
- Advantages:
- High Efficiency: Can quickly remove thick layers of grease, significantly reducing cleaning time compared to traditional methods.
- Versatile Compatibility: Works well on various metals such as steel, aluminum, copper, and their alloys, adapting to different industrial applications.
- Cost-Effective: A relatively small amount can achieve excellent degreasing results, lowering overall cleaning costs in industrial settings.
- Application Scenarios:
- Automotive Industry: Used to clean engine parts, transmission components, and chassis before assembly or maintenance, ensuring proper function and longevity.
- Metal Fabrication: In workshops, it degreases metal sheets, rods, and fabricated parts prior to machining, welding, or plating to guarantee quality workmanship.
- Machinery Maintenance: Keeps industrial machinery like pumps, turbines, and generators running smoothly by removing accumulated grease and preventing overheating due to clogged cooling fins.
