Why Is Industrial Sodium Tripolyphosphate Also A Multifunctional Ceramic Additive?

Whether it is in house decoration, industrial production, or common tableware at home, everyone can see the presence of ceramic materials. Ceramic additives have important practical significance for reducing energy consumption in ceramic production, improving process performance, reducing production costs, and improving production efficiency. With so many additives, why is industrial sodium tripolyphosphate said to be a multifunctional ceramic additive?

Sodium tripolyphosphate is also called water-reducing agent, degumming agent, and decoagulant. Its main function is to improve the fluidity of ceramic blanks and glaze slurries, so that the slurry has the least moisture, better fluidity, and no flocculation. Precipitation is easy to operate and can be used in various processes.

1. Dispersion

The system formed after solid particles are dispersed in a liquid medium should belong to the colloid category. This system is thermodynamically unstable and the particles have a tendency to agglomerate. At this time, adding the ceramic additive sodium tripolyphosphate prevents the agglomeration of the ceramic particles by interacting with the surface of the ceramic particles, which can prevent the agglomeration of the particles and make the components of the raw material evenly dispersed in the liquid medium.

2. Suspension Stabilization

The suspension stabilization mechanism of sodium tripolyphosphate is actually similar to the dispersion effect. Some solid particles that are insoluble or slightly soluble in water can be dispersed relatively evenly in the liquid medium with the help of sodium tripolyphosphate, forming a fine high suspension. , a stable liquid-solid system that can flow and play a role in improving the suspension stability of the slurry.

3. Water Reducing Effect

Here’s the key point: Sodium tripolyphosphate is a water-reducing agent commonly used in ceramic additives. The function of sodium tripolyphosphate is to improve the performance of the slurry so that the slurry has appropriate viscosity, good fluidity and high solid content under low moisture conditions, so as to facilitate operation and achieve the purpose of energy saving and consumption reduction.

In the preparation process of ceramic raw materials, ceramic additives are indispensable in various processes such as powder preparation, slurry and plastic blank preparation, molding, drying and sintering. The application of sodium tripolyphosphate is also an important additive that is directly related to the improvement of product quality, performance, variety and process conditions.
