Why is technical grade sodium tripolyphosphate called the "monosodium glutamate" in the ceramic industry? The manufacturer tells you

 With the development of modern ceramic technology, the production trend of the ceramic industry has gradually shifted to intelligentization and automation. This change not only puts forward high requirements on the performance of ceramics, but also puts forward higher requirements on the raw materials and additives for the production of ceramics. Technical grade sodium tripolyphosphate diluent is an additive commonly used in the ceramic industry. Because of its small amount of addition, it also plays an excellent role and is called "monosodium glutamate" in the ceramic industry.

When the ceramic slurry is prepared for the casting process, it is necessary to achieve uniform suspension and dispersion of the ceramic slurry and good fluidity. At the same time, in the process of casting ceramic sheets, it is also necessary to ensure good leveling and avoid pinholes and craters in the ceramic film. It is necessary for the dispersant to have good wetting and dispersing properties, suspension stability, and good grinding process Grinding and reducing effect.

Therefore, sodium tripolyphosphate diluent is also called water reducer, degumming agent, decoagulant. Its function is mainly used to improve the fluidity of ceramic blank and glaze slurry, to make the slurry with the least moisture, better flow performance, no flocculation and precipitation, and easy operation.

It is called "monosodium glutamate" in the ceramic industry because sodium tripolyphosphate only needs to be added to the different processes of ceramic production in a small amount to play a good role:

1. For spray-dried materials, due to the reduced water content, the energy consumption for drying can be reduced, and the output of powder can be increased.

2. For the glaze slurry, it can prevent flocculation and reduce the water content under the guarantee of the production process requirements. This is particularly important for certain products that require a large glaze slurry and high solid content.

In ceramic slurry, because of the large specific surface area and strong surface energy of the ceramic powder, it is very easy to agglomerate, which affects the production conditions such as the dispersion and viscosity of the ceramic slurry. Some manufacturers use tripolyphosphate sodium grinding aid thinner. Under the same process requirements, ball milling time can be reduced and power consumption can be saved. However, when some manufacturers use the sodium tripolyphosphate thinner, due to improper use or other factors, the effect of the thinner is affected. This is because not all sodium tripolyphosphate can be effective in the ceramic industry.

At present, Chongqing Chuandong Chemical Group, which specializes in the production of ceramic blanks, glazes, etc., has ceramic grade sodium tripolyphosphate with less dosage and lower impurities than ordinary ones. The manufacturers all specify ceramic grades, indicating that the rational selection of ceramic additives can also save energy consumption and reduce production costs for ceramic enterprises.
