Functions of KR-706 High-Efficiency Degreaser

KR-706 High-Efficiency Degreaser (often cross-referenced with industrial water treatment codes like TH-706) is a multi-functional, composite cleaning and dispersing agent. It is formulated using a blend of surfactants, chelating agents, and penetrants specifically designed to remove heavy oils, organic films, and greasy slime from industrial equipment and cooling water systems.

Here are its primary functions and mechanisms:

1. Powerful Emulsification and Oil Removal

The primary function of KR-706 is to break down, emulsify, and lift heavy oil contaminants.

Surface Cleaning: It strips away stubborn oil films, motor oils, lubricants, and processing glues that adhere to the inner surfaces of heat exchangers, condensers, and piping.

Water Phase Emulsification: It targets and emulsifies free floating or emulsified oils trapped within the circulating water, preventing them from redepositing onto clean metal surfaces.

2. Biological Slime and Organic Film Stripping

In open or closed circulating water systems, bacteria and algae often mix with oil to create a sticky, resilient biological slime.

KR-706 acts as a bio-slime stripper, penetrating the sticky outer matrix of the slime, loosening its grip on the piping, and allowing the water flow to flush it away.

3. Synergistic Scale Inhibition and Dispersion

Beyond basic degreasing, the composite formula includes polymeric dispersants and chelating agents.

Dispersing Solubilization: Once oil and dirt particles are lifted, KR-706 keeps them suspended in the water phase. This prevents them from agglomerating into larger clusters that could cause localized blockages.

Particulate Scale Control: It helps disperse calcium salts, iron oxides, and airborne dust particles so they don't combine with organic oils to form hard, baked-on composite scales on high-temperature heat exchange faces.

4. Penetration and Wetting Enhancement

KR-706 significantly lowers the surface tension of water. This h3 wetting capability allows the chemical to rapidly penetrate tight cracks, crevices, and thick, aged layers of fouled grease that standard rinsing chemicals cannot reach.

5. Metal Surface Passivation Protection (Anti-Secondary Pollution)

Industrial degreasers can sometimes leave bare metal vulnerable to flash rusting once the oil layer is stripped. KR-706 is formulated to clean without aggressively etching the base metal, often providing temporary surface passivation during the wash cycle to prevent immediate secondary corrosion or rust.

Typical Application Contexts

Because of these combined functions, KR-706 is most frequently utilized in:

Pre-Commissioning Cleanouts: Cleaning newly installed pipelines and systems to remove anti-rust oils, greases, and construction debris.

System Remediation: Flushing out older cooling water systems that have suffered an accidental oil leak (e.g., from a broken heat exchanger tube).

Maintenance Shock Dosing: Periodically cleaning systems prone to high organic or oil loading.
