उत्पाद वर्णन

Cooling water treatment chemicals are specialized formulations used to improve the efficiency and longevity of cooling systems such as cooling towers, chillers, and heat exchangers. These chemicals help control problems like scale, corrosion, microbial growth, and fouling. Heres a breakdown of the types of cooling water treatment chemicals and their typical functions:

1. Scale Inhibitors

Purpose: Prevent the formation of mineral scales (e.g., calcium carbonate, calcium sulfate).
Common Chemicals:

• Phosphonates (e.g., HEDP, ATMP)

• Polyacrylates or Polymaleic acids

• Organophosphates

Mechanism: Disrupt crystal formation or disperse scale-forming salts.

2. Corrosion Inhibitors

Purpose: Protect metal surfaces (like steel, copper, or aluminum) from rust and corrosion.
Common Chemicals:

• Zinc salts

• Molybdates

• Phosphates

• Azoles (e.g., tolyltriazole for copper protection)

Mechanism: Form a protective film on the metal surface or neutralize corrosive ions.

3. Biocides and Algaecides

Purpose: Control microbial growth such as bacteria, algae, and fungi that cause biofouling.
Types:

• Oxidizing Biocides: Chlorine, bromine, sodium hypochlorite, chlorine dioxide.

• Non-oxidizing Biocides: Isothiazolinones, glutaraldehyde, DBNPA.

Mechanism: Kill or inhibit microorganisms by disrupting cell walls or interfering with metabolism.

4. Dispersants and Surfactants

Purpose: Keep suspended solids, organic materials, and biofilms dispersed and prevent fouling.
Common Chemicals:

• Polyacrylic dispersants

• Surfactants (non-ionic or anionic types)

5. pH Control Agents

Purpose: Maintain optimal pH for corrosion and scale control (typically around 6.59.0 depending on system).
Common Chemicals:

• Alkalinity Builders: Sodium hydroxide, sodium carbonate

• Acidifiers: Sulfuric acid, hydrochloric acid

6. Antifoaming Agents

Purpose: Reduce or eliminate foam caused by organics or surfactants.
Common Chemicals:

• Silicone-based compounds

• Polyether-modified polysiloxanes

Typical Cooling Water Treatment Chemical Formulation Example:

A blended formulation might contain:

• 1020% phosphonate (scale inhibitor)

• 25% tolyltriazole (corrosion inhibitor for copper)

• 13% non-oxidizing biocide

• 15% dispersant polymer
