  • Closed Circulation Water Corrosion Inhibitor

    1. The closed-loop water corrosion inhibitor is composed of phosphorus-free corrosion inhibitors, high-efficiency polymers, and special surfactants.
    2. Once added to the system, it quickly forms a dense protective film on the heat exchange interface, which lasts for a long time and provides good corrosion inhibition for heat exchange equipment made of different materials.
    3. The product is highly adaptable and applicable to a wide range of water systems, offering high corrosion inhibition rates and stable performance under high concentration ratio conditions.
    4. This phosphorus-free, environmentally friendly water treatment agent meets environmental discharge requirements in all regions.

    BENEFITS & FEATURES

    1. The use of closed-loop water corrosion inhibitors should be combined with the water quality of the circulating cooling water system to determine the dosage, typically controlled between 30 and 100 ppm.
    2. The product should be added continuously, based on the amount of wastewater discharged.
    3. The product has good compatibility and can be used with biocides and other agents.
    4. It is widely used in power generation, petrochemicals, steel, pharmaceuticals, oil and gas fields, and other industrial sectors.

Mechanisms of Corrosion Inhibition in Closed Circulation Systems

Corrosion in closed circulation systems arises from the interaction between water and metal surfaces, driven by factors like oxygen, pH levels, and temperature. To combat this, corrosion inhibitors are employed, functioning through various mechanisms to form a protective barrier on metal surfaces.
Corrosion Inhibition Mechanisms:
Film Formation: Inhibitors, such as those in our closed circulation water corrosion inhibitor, quickly form a dense, protective film on heat exchange surfaces. This film acts as a barrier to corrosive elements, reducing direct contact between metal and water.
Chemical Reaction: Some inhibitors react chemically with metal surfaces to create a stable, insoluble compound that hinders further corrosion.
Adsorption: Inhibitors can adsorb onto metal surfaces, modifying the electrochemical properties and reducing corrosion rates.
Our closed circulation water corrosion inhibitor stands out for its phosphorus-free composition, ensuring environmental safety while providing high-efficiency corrosion protection. It is highly adaptable, suitable for a variety of industrial water systems, and maintains stability even under high concentration ratios. This product offers a superior solution by combining robust corrosion inhibition with eco-friendly attributes, meeting rigorous environmental discharge requirements and enhancing the longevity and performance of your equipment.

 

Optimizing Dosage of Closed-Loop Water Corrosion Inhibitors for Different Water Qualities

Effectively managing corrosion in closed-loop systems requires optimizing the dosage of corrosion inhibitors based on water quality. The dosage must be tailored to address variations in factors like pH, hardness, and contamination levels, which influence the inhibitor's performance.
Dosage Optimization Strategies:
Water Quality Assessment: Accurate assessment of water quality parameters is essential to determine the optimal inhibitor concentration. Factors such as pH, alkalinity, and the presence of impurities affect how inhibitors interact with metal surfaces.
Dose Adjustment: Based on the water quality analysis, adjust the inhibitor dosage within the recommended range (typically between 30 and 100 ppm) to ensure effective protection without overuse.
Continuous Monitoring: Regular monitoring of both water quality and inhibitor levels ensures that the dosage remains optimal as water conditions change.
Our closed circulation water corrosion inhibitor excels in this regard by offering high adaptability to various water qualities. Its robust formulation ensures stable performance and effective corrosion inhibition across different conditions, reducing the need for frequent adjustments.
