Sodium Tripolyphosphate: A Key Player in Metal Processing and Oil Removal

Enhancing Production Efficiency in Metal Processing

In metal processing, reducing labor intensity, improving product quality, and achieving energy savings are paramount. Lubricating oil is typically used for these purposes, but it often leaves residual oil pollution on metal parts. Industrial Sodium Tripolyphosphate (STPP) serves as an effective metal oil removal agent, playing a crucial role in maintaining clean surfaces and enhancing production efficiency.

The Multifaceted Role of Surfactants

Reducing Surface Tension and Enhancing Penetration

Adding surfactants to cleaning solutions can significantly reduce surface tension, thus enhancing the infiltration effect. This allows the cleaning solution to penetrate more deeply and effectively into the oil-contaminated surfaces.

Superior Emulsification and Cleaning Capabilities

Surfactants possess excellent emulsification properties, allowing them to clean and decontaminate simultaneously. This dual action ensures that metal surfaces are thoroughly cleaned of oil residues.

Efficient Metal Oil Removal

Metal oil removal agents work rapidly to cleanse metal surfaces without causing corrosion. Their formulas are simple, cost-effective, and performance-stable. Common surfactant components include:

  1. Anionic Surfactants:

    • Oleate triethanolamine soap
    • Sodium dodecyl benzene sulfonate
    • Sodium dodecyl sulfate
    • Sodium stearate
    • Sodium polyoxyethylene lauryl sulfate
    • Fatty alcohol polyoxyethylene ether carboxylate
    • Lauryl glycerol phosphate escin
  2. Non-Ionic Surfactants:

    • Sodium Tripolyphosphate, a key inorganic salt, enhances cleaning agents by improving tolerance to hard water and dispersing residual fats on surfaces.

The Unique Mechanism of Surfactants

STPP utilizes the hydrophilic and oil-attracting groups in its molecular structure to form an interface adsorption between oil and solution. The hydrophilic group faces the solution, while the oil-attracting group points towards the oil contamination. This orderly arrangement significantly reduces the interface tension between oil and liquid.

When stirred, the oil stains loosen and disperse into small oil beads, detaching from the workpiece surface. The surfactant’s emulsifying and dispersing effects prevent oil drops from merging and re-adhering to the workpiece, resulting in an excellent cleaning outcome.

High Stability and Versatile Applications

Non-ionic surfactants like STPP are highly stable, resistant to strong electrolytes, acids, and bases. They exhibit strong compatibility with other surfactants, excellent solubility in various solvents, and do not strongly adsorb onto solid surfaces.

Composition of Metal Oil Removal Agents

Metal oil removal agents generally consist of a washing agent and a surfactant. These can be formulated with complex surfactants, organic solvents, corrosion inhibitors, inorganic salts, removing agents, and water in appropriate proportions.
