Sodium tripolyphosphate is an important additive in the preparation of ceramic raw materials

In recent years, with the improvement of people's living standards and consumption upgrading, the ceramic industry has also experienced rapid development. Ceramic industry in China has become the world's largest consumer market for ceramic production, and ceramic craftsmanship has reached a leading level in the world. The development of gelatinizers is also flourishing, and the categories are changing rapidly.

Sodium tripolyphosphate is an important additive in the preparation of ceramic raw materials, which not only solves the problem of mud, but also reduces production costs and helps ceramic production enterprises improve efficiency.

In ceramic production, the water content of mud is generally controlled at 29% to 34%, but under such a low water content, the fluidity of mud containing clay minerals is poor. To solve this problem, people often add an appropriate amount of gel release agent to the mud.

What is sodium tripolyphosphate adhesive?

It is used to improve the flowability of mud, making its viscosity appropriate under low moisture conditions and easy to pour.

The benefits of adding sodium tripolyphosphate as a gelling agent:

1. Reduce the water content of the mud and increase its fluidity.

2. Shorten the grouting time, reduce the shrinkage rate, and reduce the deformation of the billet.

3. Increase the suspension of the mud to prevent the raw material particles from settling easily.

4. Make the green body easy to demould, thereby reducing the cracking of the green body.

Sodium tripolyphosphate meets the conditions for a gel release agent:

1. It can dissociate into monovalent cations with strong hydration ability.

2. It can directly dissociate or hydrolyze, providing sufficient OH^- to make the clay mud alkaline.

3. Cations can form difficult to tolerate salts or stable complexes with harmful ions that cause flocculation in the mud.

With the development of modern ceramic technology, various additives are increasingly widely used and play an increasingly important role in the production of building ceramics. Sodium tripolyphosphate, also known as a gel breaking agent for ceramic production of "monosodium glutamate," is a dispersant additive for ceramic slurries. Although the dosage is small, it often plays a very prominent role in energy conservation and consumption reduction, new product development, and the creation of new processes.
