How Ceramic Diluting Agent Disperses Ceramic Slurry
In the production of special ceramics, the preparation of the slurry has a great influence on the normal operation of the entire production line and the performance of the finished product. The preparation of qualified slurry is inseparable from Ceramic Diluting Agent, which can prevent the re-agglomeration of particles, make the ceramic slurry have a relatively stable dispersion, and finally obtain a ceramic body with uniform internal microstructure and no defects, which improves the product quality. Therefore, the advantages and disadvantages of Ceramic Diluting Agent and the technology used are increasingly being paid attention to.
So how much do you know about such an important dispersant? The mechanism of action of Ceramic Diluting Agent. The ceramic slurry contains a large number of solid particles, which will be in irregular motion under the action of thermal motion, gravity and stirring, and there are a large number of relative motions and collisions. Whether the moving particles become agglomerated particles after collision depends on Van der Waals force, Coulomb force The combined effect of the three forces of force, and steric hindrance.
Therefore, in order to keep the ceramic powder particles in a stable suspension, the repulsive force between the particles must be increased to maintain the dispersibility of the ceramic slurry. For this reason, Ceramic Diluting Agent must have two opposite properties of hydrophilicity and lipophilicity at the same time in molecular structure, so that it can interact with the surface of ceramic particles in suspension, thereby reducing the aggregation of solid or liquid particles in the dispersion system, and also can prevent the settling and agglomeration of solid particles and form a stable suspension colloid.
Through the above introduction and analysis of How Ceramic Diluting Agent Disperses Ceramic Slurry, hope it helps you.
