Water contains considerable amounts of scale forming constituents , for eg,
Calcium and Magnesium carbonates, sulphates, Magnesium hydroxide, Silica etc. The
scale deposit on metal parts and inside pipeline of heat exchangers, evaporators,
boilers, compressors, solar heaters, Generators, AC units and water cooling circuits.
: Antiscalants: they are surface active materials that interfere with precipitation reactions in three primary ways:
- Threshold inhibition: it is the ability of an antisclant to keep supersaturated solutions of springly soluble salts.
- Crystal modification: it is the property of an antiscalants to distort crystal shapes, resulting in soft non adherent scale. As a crystal begin to form at the submicroscopic level, negative groups located on the antiscalant molecule attack the positive charges on scale nuclei interrupting the electronic balance necessary to propagate the crystal growth. When treated with crystal modifiers, scale crystals appear distorted, generally more oval in shape, and less compact.
- Dispersion: dispersancy is the ability of some antiscalants to adsorb on crystals or colloidal particles and impart a high anionic charge, which tends to keep the crystals separated. The high anionic charge also separates particles from fixed anionic charges present on the membrane surface.
Safety & Handling
