HLH-103 Phosphorus-Free High-Temperature Corrosion Inhibitor Solution
Phosphorus Free High Temperature Corrosion Inhibitor

HLH-103 Phosphorus-Free High-Temperature Corrosion Inhibitor Solution

HLH-103 is a polymer surfactant containing highly polar groups such as nitrogen (N) and oxygen (O). Free of phosphorus (P), chloride (Cl), metals, and other toxic substances, it is environmentally friendly and safe for downstream processing. BXH-103 features excellent oil solubility, a high boiling point, and superior thermal stability, with a decomposition temperature exceeding 500℃. The product exhibits strong adsorption on metal surfaces, forming a dense monomolecular or polymolecular film and a passivation layer similar to 316 or 317 stainless steel. This protective layer effectively prevents high-temperature naphthenic acid corrosion.

    Product Features

    • High Efficiency and Cost-Effectiveness: Requires low dosage; 20-35% of the stock solution can produce 1 ton of finished products.
    • Versatile Solubility: Soluble in aromatics and diesel without requiring specific solvents, addressing flash point limitations.
    • Anti-Emulsification Properties: Prevents crystal precipitation in aqueous environments and ensures smooth injection without pump blockages.
    • Superior Corrosion Inhibition: Demonstrates a corrosion inhibition rate of ≥95% under standard conditions, offering excellent protection for metal surfaces.
    • Thermal Stability: Decomposition temperature exceeds 500℃, ensuring reliable performance under high-temperature conditions.
