Corrosion and Scale Inhibitor

Corrosion and scale inhibitor is an important water treatment agent, which is mainly used in circulating cooling water system, such as power plants, chemical plants, central air conditioning, etc. to prevent scale formation and metal corrosion. These products are usually compounded from a variety of ingredients, including chelating agents, dispersants, corrosion inhibitors, etc., which work together to achieve the effect of scale and corrosion inhibition.

What are Corrosion Inhibitors and Scale Inhibitors?

Corrosion and scale inhibitors are specially tailored chemicals that, when added at low concentrations in water, delay or prevent the formation of scale, which would normally form in water. Corrosion and scale inhibitors are similar to preventing scaling in washing machines, and similar chemicals are used. Ultimately, inhibition can be achieved by adding substances that react with the potential scaling material to achieve a thermodynamically stable region, or by adding substances that inhibit crystal growth. The use of these chemicals is therefore attractive because very low doses (a few ppm) are sufficient to prevent prolonged fouling of surfaces or equipment treatments. The exact mechanism of scale inhibitors is not fully understood.

Corrosion and scale inhibitor is a widely used chemical agent in water treatment, mainly used to prevent equipment scaling and corrosion, to protect the safe operation of pipelines and normal use of equipment, improve production efficiency and reduce production costs. Its main role includes.

1, Prevent corrosion: corrosion inhibitor in the corrosion inhibitor can form a protective film on the metal surface in the pipeline to prevent the corrosive effect of the medium on the pipe wall, thus reducing or delaying the corrosion reaction of the metal to protect the metal surface of the equipment and pipeline, to prolong its service life.

2, Prevent limescale: Scale inhibitors interfere with the crystallization and deposition process of minerals in water, preventing scale from adhering and forming in pipes, reducing clogging of pipes and affecting flow rates, and keeping water systems running smoothly and efficiently.

3, Extend pipelines life: by preventing corrosion and limescale formation, corrosion and scale inhibitor can effectively extend the service life of the pipelines, reduce the number of repairs and costs.

4, Improve efficiency: the use of corrosion and scale inhibitors can improve productivity and reduce downtime and maintenance costs in the production process.

5, Protect equipment safety: By preventing corrosion and scale formation in pipelines, corrosion and scale inhibitors can ensure the safe operation of equipment and reduce safety risks.

6, Cleaning and maintenance role: corrosion and scale inhibitors can keep the water system clean and in good condition, to prevent the accumulation of scale, rust and other deposits, reduce the frequency of cleaning and maintenance of pipelines and equipment. At the same time, they can also remove the slight scale layer or rust that has been formed and restore the normal work of equipment and pipelines.

1. Personal safety protection

Wear protective equipment: the operator should wear working clothes, protective glasses and gloves to avoid the corrosion and scale inhibitor splashing into eyes or skin.

Avoid inhalation: When configuring and using corrosion and scale inhibitor, maintain a well-ventilated environment to avoid inhalation of its vapor or mist.

2. Correct operation and proportioning

Follow the instructions: Strictly follow the instruction manual of corrosion and scale inhibitor to ensure the correct proportion and dosage.

Uniform dosage: In the process of dosage, make sure that the corrosion and scale inhibitor is uniformly dispersed in the water, avoiding the situation that the local concentration is too high or too low.

3. Water quality monitoring and adjustment

Regular monitoring: regularly monitor the water quality index, such as hardness, alkalinity, pH value, etc., in order to understand the using effect of corrosion and scale inhibitors and the changes of water quality.

Timely adjustment: according to the water quality monitoring results, timely adjust the adding dosage and proportioning of corrosion and scale inhibitor to ensure its effectiveness and economy.

4. Equipment maintenance and management

Clean equipment: regularly clean the inside of the equipment to prevent the accumulation of dirt and sediments, affecting the effect of corrosion and scale inhibitor.

Check the dosing system: regularly check the operation of the dosing system to ensure accurate and stable dosing.

5. Sewage and clean

Regular sewage: According to the instructions, carry out sewage operation regularly to remove the impurities and sediments in the system.

Clean up the limescale: when stopping the furnace or system shutdown, the limescale should be cleaned up manually to prevent it from blocking the pipeline or affecting the performance of the equipment.

6. Storage and Custody

Correct storage: The corrosion and scale inhibitor should be stored in a cool, ventilated and dry warehouse, avoiding direct sunlight and rain.

Keep away from children: Store the corrosion and scale inhibitor out of children's reach to prevent accidental ingestion or misuse.

7. Other Precautions

Avoid mixed use: Do not mix different brands or types of corrosion and scale inhibitors to avoid adverse reactions.

Pay attention to environmental protection: when using corrosion and scale inhibitors, pay attention to environmental protection requirements.
