Scien Green SGR0802 Azole-Containing Corrosion & Scale Inhibitor for Industrial Circulating Water
Product Highlights
1. Blended with special azole compounds, provides targeted anti-corrosion protection for copper, brass and carbon steel, effectively avoiding copper surface pitting corrosion.
2. Dual-function integrated formula, simultaneously inhibits calcium carbonate, calcium sulfate and silicate scale formation on heat transfer surfaces.
3. Maintains stable performance under harsh water conditions including high hardness, high alkalinity and high concentration multiple.
4. Low-foam liquid formulation prevents foam overflow in cooling towers and will not block system water circulation.
5. Contains polymer dispersants to disperse iron oxide, mud and suspended deposits, reducing heat exchange efficiency loss.
6. Good compatibility with common oxidizing and non-oxidizing biocides; low effective dosage cuts long-term chemical operation costs.

Performance Characteristics:
（1）Low phosphorus content, non-toxic, environmentally friendly, classified as a green scale and corrosion inhibitor.
（2）The unique feature of this agent lies in its fatty amine component, which is oil-soluble. When added to water in low doses, it forms a microemulsion with the help of surfactants. Upon contact with metal surfaces, it preferentially self-enriches at the solid-liquid interface through ether bonds and amine groups in its molecules. The long hydrocarbon chains orient outward, forming a hydrophobic film. This results in a high local concentration of the inhibitor at the interface, effectively inhibiting metal corrosion. The hydrophobicity of the high-resistance hydrophobic liquid film formed at the interface hinders the nucleation, growth, and deposition of hydrophilic inorganic scales. It exhibits good synergistic effects with other active components of the inhibitor, effectively suppressing foulant adhesion and deposition on metal surfaces. Due to the structural characteristics of the fatty amine, it also possesses good penetrative, dispersive, and stripping actions against biological slime in the system, enhancing bactericidal effects.
Application: This product is particularly suitable for open recirculating cooling water systems using polluted water sources or municipal reclaimed water as makeup water. It can improve heat exchange efficiency, reduce equipment maintenance, and extend equipment service life.
Usage:
Dosage varies depending on the water quality indicators and process parameters of the application system. Generally, based on the makeup water volume, the dosage concentration should be controlled at around 20-50 mg/L. Suitable for pH range 7.0 – 9.5.
Packaging, Storage & Transportation:
Packed in 25 kg, 200 kg, or 1000 kg plastic drums. Store in a cool, dry place. Shelf life is twelve months. Handle with care during transportation to prevent impact.
