The common inorganic dispersants are silicates and alkali metal phosphates (such as sodium hexametaphosphate, sodium tripolyphosphate and sodium pyrophosphate).

Dispersants in chemical raw materials can make the particles disperse evenly in the medium to form stable suspension. There are many materials that can be used as dispersants. Generally, they are divided into two categories: inorganic dispersants and organic dispersants, while industrial grade sodium hexametaphosphate belongs to inorganic dispersants.

Sodium hexametaphosphate dispersant is an interfacial activator with both hydrophilic and hydrophilic properties in molecule. It can evenly disperse inorganic and organic pigments which are difficult to dissolve in liquids. It can also prevent the settling and condensation of solid particles and form the necessary medicaments for stabilizing the suspension.

Dispersants are defined as substances in which dispersants can reduce the aggregation of solid or liquid particles in a dispersion system. It is easy to form dispersion and suspension when adding dispersant and suspension in the preparation of emulsifiable oil and wettable powder, and keep the relative stability of the dispersion system.

Sodium hexametaphosphate is an additive that can improve the dispersibility of solid or liquid materials. In the grinding of solid dyes, the addition of dispersant can help to crush the particles and prevent the agglomeration of the crushed particles and keep the dispersion stable. Oily liquids insoluble in water can be dispersed into very small droplets under high shear stirring. After stopping stirring, they are stratified quickly under the action of interfacial tension. When mixed with industrial sodium hexametaphosphate dispersant, stable emulsion can be formed.

The industrial grade sodium hexametaphosphate produced by Chongqing Chuandong Chemical Group is produced by the thermal process of authentic phosphoric acid. The chain length of the product is strictly tested. It can be used in refractories, industrial soft water, detergents, ceramics and other industrial additives.
