No Comments

Titanium dioxide, also known as titanium dioxide, chemical formula TiO2, is an important inorganic chemical pigment in the form of white solid or powder. It is non-toxic, has high whiteness and brightness, and is considered to be the best white pigment to improve the whiteness of materials. It is widely used in coatings, plastics, rubber, paper, ink, ceramics, glass and other industries. Titanium dioxide is closely related to the national economy and is known as the "barometer of economic development." Especially in the field of coatings, the main function of titanium dioxide is to whiten, improve the color and texture of the product, and at the same time, it can also play anti-corrosion, protect the substrate, increase the thickness and service life of the coating, etc.

Dispersant is one of the commonly used surfactants in many industries today, especially in the pigment industry, where the application of dispersants is particularly important. Dispersants can improve the overall gloss of the pigment surface, prevent color floating, reduce viscosity, increase pigment loading, reduce flocculation, increase color development and many other functions.

Types of liquid disperse dye dispersants

Powdered disperse dyes have a higher dispersant content, accounting for about 60% of the total dye, and are mostly anionic; while liquid disperse dyes have a lower dispersant content, accounting for about 20% of the total dye. Available dispersant types There are many, including nonionic, anionic and hyperdispersants. Compared with powdered disperse dyes, the dispersant content of liquid disperse dyes is greatly reduced. Although it brings advantages to printing and dyeing such as increased dye uptake and reduced pollutants in printing and dyeing wastewater, it will also reduce dye grinding efficiency and liquid dye stability. Therefore, choosing the appropriate dispersant is critical for the preparation of liquid disperse dyes.

The role of dispersants in water-based paints

The main function is to disperse the particles that need to be dispersed in the water-based paint on the surface so that they have better stability. Gloss-improving dispersants can improve the gloss of water-based paints, improve the flatness of the surface of water-based paints, and maintain a certain level of stability. In this way, when sunlight hits the wall, the water-based paints will emit good gloss. Increase color transparency and saturation

What is the function of water-based paint dispersants?

The function of the water-based paint dispersant is to disperse the pigments and fillers very finely and evenly in the paint to prevent the occurrence of sedimentation, agglomeration and flocculation. Especially in water-based systems, affected by the viscosity, the pigments and fillers are affected by their own gravity. , is prone to sedimentation, so it is necessary to add a dispersant to improve storage stability.

Difference Between Dispersants and Surfactants

The main difference between dispersants and surfactants is that dispersants improve the separation of particles in a suspension, while surfactants are substances that reduce the surface tension between two phases of a substance. Dispersants are a form of surfactant. But all surfactants are not dispersants. In addition to acting as dispersants, surfactants can also act as detergents, wetting agents, emulsifiers, and foaming agents. Usually, they are organic compounds.
