What are the different types of dispersants?

Dispersant is an important chemical additive used to improve the dispersion and stability of powders or granules in liquid media. According to different application areas and media, dispersants can be divided into the following different types:

Surfactant dispersants: This type of dispersant mainly improves the dispersion properties of powders or particles by reducing surface tension. They are usually composed of hydrophilic and hydrophobic molecular structures that interact with the particle surface through non-polar groups to generate repulsive forces between particles, thus preventing agglomeration.

Polymer dispersants: Polymer dispersants mainly improve the stability of powders or particles through the adsorption and bridging of polymer chains. They are usually long polymer chains polymerized from multiple monomers, which can wrap and fix particles in the medium to prevent their agglomeration.

Solid dispersant: This type of dispersant mainly improves the dispersion performance of solid powder or particles in liquid media by modifying their surface. They usually coat the surface of solid particles with a lyophilic coating to increase the wettability and stability of the particles in liquids.

Synthetic polymer dispersants: This type of dispersant is a specially synthesized polymer compound with excellent dispersion and stability properties. They are usually polymerized from multiple monomers and are carefully molecularly designed to achieve optimal dispersion of powders or granules.

Natural polymer dispersants: Natural polymer dispersants are polymer compounds extracted from natural substances, such as starch, cellulose, etc. They are environmentally friendly, safe, easily biodegradable, and can be used in a variety of applications.

Mechanical Dispersants: Mechanical dispersants involve the use of specialized equipment to physically disperse the oil. This may include equipment such as booms, skimmers and pumps to contain and remove oil from the water. Mechanical dispersants can also use high-pressure injectors or pumps to break up floating oil into smaller droplets. While they don’t technically disperse oil, they aid in the dispersion process by physically breaking up oil slicks.

Lubricating oil dispersants: Lubricating oil dispersants are additives used in lubricating oils, such as engine oil or hydraulic oil, to prevent the formation of deposits and sludge. They work by dispersing insoluble particles, such as soot, carbon or metal wear debris, that can accumulate in the lubricant over time.

In short, there are many types of dispersants, and the appropriate type of dispersant needs to be selected according to the specific application field and medium. At the same time, the quality and application effect of the dispersant will also be affected by its production process, ingredients, molecular structure and other factors. Therefore, it is very important to choose a high-quality dispersant supplier. Shanghai Minglan Chemical Co., Ltd. is a high-quality lubricant dispersant supplier.
