Techniques
Cyanamer®: A Powerful Weapon in Environmental & Water Treatment
Chapter 1: Techniques
Scale Inhibition and Dispersant Mechanisms
Cyanamer® products employ two primary mechanisms to combat scale formation:
- Crystal Growth Inhibition: Cyanamer® molecules adsorb onto the surface of growing mineral crystals, disrupting their normal lattice structure and hindering further growth. This prevents the formation of large scale deposits.
- Dispersion: Cyanamer® products act as dispersants, preventing existing scale particles from aggregating into larger, more problematic deposits. They keep these particles suspended in the water, minimizing their impact on system efficiency.
Specific Techniques Employed by Cyanamer® Products:
- Polycarboxylate Polymers: Cyanamer® P-100 is an example of this type. These polymers effectively inhibit the growth of calcium carbonate and calcium sulfate, the most common scaling minerals.
