The function and mechanism of scale inhibitor

1.Inhibition of precipitation function: In the system of scale inhibitor, the ion product’s values of the cationic and anionic precipitates of the fouling component are much larger than the critical precipitated ion product values without the scale inhibitor. 


2.Dispersion function: In the presence of scale inhibitors, the precipitated particles are small particle size and difficult to cohesive. It is difficult to settle than the absence of scale inhibitor.


3.The lattice distortion effect: In a system with a scale inhibitor, the precipitated crystals have spherical, polyhedrons.


4.Low limit effect: Scale inhibitor dosage is equivalent to the water in the fouling component is much lower and can also show its scale effect.


Scale inhibition mechanism:


1.Inhibition of precipitation effect: The scale inhibitor has the function of adsorbing insoluble calcium, magnesium salt and so on. In the presence of scale inhibitors, the scale inhibitor and the precipitation of the nucleus of the growth point of cationic binding. So that the growth of the crystal is inhibited at the ion level. It can be stably maintained in water. 


2.Prevent adhesion effect: Depending on the type of the scale inhibitor and the water quality conditions, the crystal is still growing before the crystal reaches a certain degree of size. In the presence of a scale inhibitor, the precipitated particles have an easily dispersible property in water due to the charge of the adsorbed agent and the influence of hydrated water. So that the particles adsorbed by the medicament are hard to deposit at the residence layer and the growth of the scale is suppressed. While the addition of scale inhibitor after the adsorption part of the suspension is difficult to deposit.
