The characteristic of scale inhibitor is to change the crystal shape. Scale inhibitor in water and calcium and magnesium away from the formation of stable soluble chelation, will be more calcium ions and magnesium ions stable in water, thereby increasing the solubility of calcium and magnesium salts, inhibit the scale generation. And in the laboratory evaluation test, dispersion is the remedy for chelating solubilization, and lattice distortion is the remedy for dispersion.Ĭhelating solubilization mechanism is the most obvious. The principle of scale inhibitor can be summarized as chelating solubilization, coalescence & dispersion, and lattice distortion in three categories. Scale inhibitors are chemicals that make it difficult for calcium ions and magnesium ions in water to agglomerate and achieve scale inhibition. Therefore, it is very important to stop the generation of scale, adding scale inhibitors to stop the generation of insoluble salts, as one of the most convenient and economical methods, more and more widely used by all walks of life. If the RO membrane produces a large amount of scale, it will block the membrane and cause the membrane efficiency to decrease. When water molecules pass through the RO membrane, the ions in the water will accumulate on the membrane surface because they cannot pass through the membrane, and if the concentration of calcium and magnesium ions in the water exceeds their saturation in the water, a crystallization reaction will occur and a solid precipitate, or scale, will form. RO membrane allows water molecules to pass through but prevents most ions from passing through. If hard water is used as cooling water for industrial production, it will cause the heat exchanger to produce scale, which will seriously obstruct the water flow channel and make the heat exchange effect greatly reduced, affecting the smooth production. ![]() Heating kettles for a long time heating hard water, the inner wall will form a layer of thick scale contact with hard water stainless steel or glass products will also leave white water stains after the evaporation of hard water hard water taste bad, long-term use is not good for human body. ![]() ![]() It is introduced that scale is the combination of calcium ions and magnesium ions in water with bicarbonate ions to form CaCO 3, MgCO 3 and other insoluble solid precipitates.
