Inhibiteurs de corrosion et de tartre

PBTC 50% Scale Inhibitor Supplier | 2-Phosphonobutane-1,2,4-Tricarboxylic Acid

PBTC (2-Phosphonobutane-1,2,4-Tricarboxylic Acid) is a highly efficient scale inhibitor et corrosion control agent widely used in industrial water treatment systems. It provides excellent calcium carbonate dispersion, threshold inhibition, and metal ion chelation, making it ideal for cooling water systems, reverse osmosis pretreatment, boilers, and circulating water treatment programs.

WaterCareChem supplies high-purity PBTC 50% with stable quality, competitive bulk pricing, and reliable export logistics for global customers. Our product is compatible with many phosphonate and polymer formulations and performs effectively under high alkalinity and elevated temperature conditions.

Advanced Performance Advantages of PBTC50%

This high-performance agent features a relatively low phosphorus content and combines both phosphonic acid et carboxylic acid functional groups, giving it outstanding scale inhibition and corrosion protection performance.

Compared with conventional organophosphonic acids such as HEDP or ATMP, PBTC often delivers superior results, especially under high-temperature operating conditions, where its scale control efficiency is significantly improved.

It also enhances the solubility of zinc salts, offers excellent chlorine oxidation resistance, and demonstrates strong synergistic effects when blended with polymers, zinc salts, or other phosphonates.

Because of these advantages, it is widely used in high-performance scale and corrosion inhibitor formulations for:

• Circulating cooling water systems
• Oilfield injection water treatment
• High-temperature water systems
• High-hardness and high-alkalinity water conditions
• High concentration ratio cooling towers
• Detergent formulations as chelating agent
• Metal cleaning chemicals

Key Benefits

• Excellent scale inhibition for calcium carbonate and calcium sulfate
• Strong dispersing performance in hard water systems
• Effective under high pH and high temperature conditions
• Good corrosion inhibition synergy with zinc salts and polymers
• Low phosphorus content compared with traditional phosphonates
• Suitable for zero-liquid discharge and modern water treatment programs
• Stable storage performance and easy dosing

Typical Applications

• Open recirculating cooling water systems
• Industrial boilers and condensate systems
• Reverse osmosis pretreatment chemicals
• Oilfield water treatment programs
• Detergent and cleaning formulations
• Metal surface treatment systems
• Desalination and process water treatment

PBTC vs. HEDP: Which one should you choose?

While both are organic phosphonates, PBTC outperforms HEDP in several key areas:

• Calcium Tolerance: PBTC has a much higher tolerance for calcium ions, making it better for extremely hard water.
• Oxidizing Biocides: PBTC is more stable in the presence of chlorine or bromine, which often degrade other inhibitors.
• Environmental Impact: With lower total phosphorus content, PBTC is better suited for Zero-Liquid Discharge (ZLD) and green water treatment initiatives.

Frequently Asked Questions

1. What is the main function of PBTC in water treatment? It acts as a high-efficiency scale inhibitor (antiscalant) and corrosion inhibitor. It prevents the precipitation of calcium carbonate and other mineral scales while forming a protective film on metal surfaces to prevent rust.
2. Can PBTC 50% be used in acidic conditions? Yes, it is highly stable across a wide pH range, though it is particularly valued for its ability to function in high-alkalinity (high pH) environments where other phosphonates fail.
3. Is PBTC compatible with chlorine? Yes. Unlike ATMP or HEDP, PBTC shows excellent stability in the presence of oxidizing biocides like chlorine, making it ideal for systems that require frequent disinfection.
