Commonly used inorganic dispersants include silicates, such as water glass, alkali metal phosphates, such as, sodium tripolyphosphate, shmp chemical and sodium pyrophosphate, etc… Organic dispersants include triethylhexanoic acid, ten Sodium dialkyl sulfate, methylpentanol, cellulose derivatives, polyacrylamide, Guer gum, fatty acid polyethylene glycol esters, etc…
Sodium hexametaphosphate dispersant is an auxiliary agent to improve the dispersion performance of solid or liquid materials. When solid dyes are milled, dispersing agent is added to help smash the particles and prevent the smashed particles from coagulating ink and keep the dispersion stable. The oily liquid that is insoluble in water can be dispersed into small droplets under high shear stirring. After stopping the stirring, it will quickly layer under the action of interfacial tension. And after adding sodium hexametaphosphate dispersant and stirring, it can form a stable emulsion. Its main function is to reduce the interfacial tension between liquid-liquid and solid-liquid. Therefore, dispersants are also surfactants.
