Whether in house decoration, industrial production or tableware common at home, we can see the figure of ceramic materials. Ceramic additives have important practical significance to reduce energy consumption, improve process performance, reduce production cost and improve production efficiency. With so many additives, why is industrial grade sodium tripolyphosphate also a multifunctional ceramic additive?

Sodium tripolyphosphate, also known as water reducing agent, degumming agent and coagulant, is mainly used to improve the fluidity of ceramic blank and glaze slurry, so that the slurry has the least water content, better fluidity, no flocculation and sedimentation, and is easy to operate. It is applied in various process.

Dispersion

The system formed by the dispersion of solid particles in liquid medium should belong to the category of colloid. The system is thermodynamically unstable and the particles tend to agglomerate. At this time, the addition of ceramic additive sodium tripolyphosphate prevents the agglomeration of ceramic particles by interacting with the surface of ceramic particles, which can prevent the agglomeration of particles and make the components of raw materials evenly dispersed in the liquid medium.

Suspension stabilization

In fact, the suspension stability mechanism of sodium tripolyphosphate is similar to that of dispersion. Some solid particles insoluble in water or slightly soluble in water can be evenly dispersed in the liquid medium with the help of sodium tripolyphosphate to form a fine, highly suspended and mobile stable liquid-solid system to improve the suspension stability of slurry.

Water reducing effect

Sodium tripolyphosphate is a water reducing agent commonly used in ceramic additives. The function of sodium tripolyphosphate is to improve the slurry performance and make the slurry have appropriate viscosity, good fluidity and high solid content under the condition of low moisture, so as to facilitate operation and achieve the purpose of energy saving and consumption reduction.

Ceramic additives are indispensable in the preparation of ceramic raw materials, from the preparation of powder, slurry and plastic embryo, to molding, drying, sintering and other processes. The application of sodium tripolyphosphate is also an important additive directly related to the improvement of product quality, performance, variety and process conditions.
