Aluminum Alloy Corrosion Inhibitor VanconolALI-1214

🎯 Abstract

VanconolALI-1214 phosphate ester corrosion inhibitor is an anionic corrosion inhibitor produced by phosphorylation of natural fatty alcohol polyether. Its molecular structure combines the strong adsorptivity of phosphate groups with the excellent water solubility of polyoxyethylene ether chains, enabling the formation of a dense protective adsorption film on aluminum alloy surfaces. This effectively inhibits corrosion, blackening, and white rust caused by moisture and acidic/alkaline media during machining. The product is environmentally friendly, low in toxicity, resistant to hard water and high temperatures, and exhibits good compatibility with a wide range of additives, making it a suitable corrosion inhibitor additive for aluminum alloy working fluids.

🛠️ Performance Features

Efficient Corrosion Inhibition: Forms a protective film via chelation between phosphate groups and aluminum surfaces, helping prevent pitting corrosion, discoloration (e.g., blackening, gray tarnishing), or loss of luster on aluminum alloys in working fluids.

Broad Environmental Adaptability: Resistant to acids, alkalis, and hard water (stable over pH 6–12); remains active at elevated temperatures (≤90°C) and in high-salinity environments.

Multifunctional Synergy: Provides combined lubrication, emulsification, dispersion, and antistatic functions, helping reduce the dosage of other additives in working fluid formulations.

Environmental Safety: Readily biodegradable; free from restricted substances such as APEO and heavy metals; low skin irritation potential.

Strong Formulation Compatibility: Compatible with anionic/nonionic surfactants (e.g., alcohol ethers, sulfonates), biocides, and scale inhibitors.

📝 Applications

Aluminum Alloy Working Fluids: Used as an anticorrosion/corrosion inhibitor in cutting, grinding, and lapping fluids.

Metal Cleaning and Pretreatment: Used as a rust preventive/corrosion inhibitor in degreasing and cleaning formulations.

Forming Processes and Specialty Lubricants: Used as a corrosion inhibitor, extreme-pressure additive, and lubricant in cold-rolling emulsions, stamping fluids, wire-drawing oils, and lubricant formulations.

Other Applications: Used as an additive in rust-preventive chemical products.

🧪 Application Recommendations

Aluminum Alloy Working Fluid Formulations

Dosage: Recommended addition level is 0.2%–3% of the total formulation (adjust based on water quality and machining conditions).

Formulation Example:

Base formulation: ALI-1214 phosphate ester (3%) + triethanolamine borate (1%) + lubricant (3%) + deionized water (balance).

For highly alkaline environments, a phosphorus-free corrosion inhibitor may be combined to enhance protection.

Operating Conditions

Optimal pH Range: 6.0–9.5 (protective film stability is highest within this range).

Temperature Limit: Long-term service temperature ≤80°C; avoid direct mixing with strong oxidizing agents.

⚠️ Safety and Storage

Packaging: Sealed in 50 kg / 200 kg plastic drums.

Storage: Store in a cool, well-ventilated area away from direct sunlight. Shelf life: 2 years.

Safe Handling: Wear protective gloves when handling; if product contacts eyes, rinse immediately with clean water and seek medical attention.

❓ Frequently Asked Questions (FAQ)

Q1: Is ALI-1214 corrosion inhibitor suitable for all aluminum alloy grades?

A1: ALI-1214 provides effective corrosion inhibition for most common aluminum alloy grades. However, for certain specialty alloys or alloys with special surface treatments, small-scale preliminary testing is recommended to confirm suitability and determine the optimal dosage.

Q2: Will precipitation occur when ALI-1214 is blended with other surfactants?

A2: ALI-1214 exhibits good compatibility with anionic/nonionic surfactants (e.g., alcohol ethers, sulfonates). However, compatibility testing is recommended prior to blending to ensure no precipitation or mutual performance interference occurs.

Q3: How does ALI-1214 perform under hard water conditions?

A3: ALI-1214 offers excellent hard water resistance with stability over pH 6–12, maintaining effective corrosion inhibition performance even in hard water environments.
