1. Inhibits Scale Formation: Through chelation, lattice distortion, and dispersion, it prevents calcium and magnesium ions from depositing on equipment surfaces as calcium carbonate, calcium sulfate, and other scale.
2. Highly Effective Foam Defoaming and Suppression: It can quickly destroy the foam film structure, reduce surface tension, achieve rapid defoaming, and prevent foam regeneration.
3. Inorganic Corrosion Inhibitors: Such as sodium nitrite, low cost but poor environmental performance, often used in low-hardness water.
4. Organophosphonates: Combines scale inhibition and corrosion inhibition effects, with strong chelating ability for calcium and magnesium ions, suitable for high-hardness water.
5. Polycarboxylic Acids: Excellent dispersing properties, can inhibit the formation of calcium carbonate, calcium sulfate, and other scale, often used in circulating cooling water systems.
6. Enhanced Environmental Friendliness: New scale inhibitors (such as polyaspartic acid PASP) are biodegradable, reducing phosphorus emissions and lowering the risk of eutrophication.
7. High safety: Most defoamers are non-toxic, odorless, and have no physiological activity, meeting food-grade and pharmaceutical-grade application standards.
