Chemical dispersion is a type of chemicals widely used in multiple fields. It is mainly used to disperse solid particles or liquid droplets to liquid medium and prevent them from re -aggregating. The following are several common uses of chemical dispersing agents:
Surface active agent: Chemical dispersant can be used as a surfactant, so that solid particles are dispersed evenly in the liquid. They reduce the interaction between solid particles and help the particles to be scattered in the solution. This application is common in industries such as coatings, inks, pigments, dyes.
Powder Metallurgical: In the process of powder metallurgy, chemical dispersers can be used to evenly disperse metal or ceramic powder in the additives (such as adhesive) to form a uniform mixture. This helps improve the uniformity and performance of the finished product.
Sewage treatment: In sewage treatment, chemical dispersers can help scattered suspended particles, colloids and oils into water, increasing its surface area, thereby improving the treatment efficiency. Its function is achieved by changing the surface charge of the particles or adding electrolytes to prevent particles from gathering.
Catalyst carrier: In the preparation of catalysts, chemical dispersant can be used as a carrier, which evenly disperse the catalyst particles on the carrier to improve the activity and stability of the catalyst.
Medicine industry: In the production of pharmaceutical preparations, chemical dispersers are often used to stabilize drugs in the form of suspension or emulsion, ensure the uniform distribution of drug components, and prevent precipitation and gathering.
It should be noted that different chemical dispersers are suitable for different application areas and types of materials. When using chemical dispersers, you should choose the right product according to specific needs, and follow the correct operating guidelines and safety precautions to ensure its effectiveness and safety.
