Carbon black is a black powdery substance produced by incomplete combustion or thermal cracking of hydrocarbon compounds under strictly controlled process conditions. Its main component is elemental carbon and contains a small amount of oxygen, hydrogen and sulfur. Carbon black particles are approximately spherical in shape and have a particle size between 10 and 500 μm. They are one of the oldest industrial products.

The influence of the surface tension difference on the floatation of the paint in the ordinary color mixing, it is often found that some color paste in the white base paint is difficult to disperse evenly, soon there is color separation or floating phenomenon, or paint can not open the effect. In the process of making paint, the making of white paste is different from that of color paste,

In the process of paint production and application, we often meet the problem of floating color, when the paint appears floating color, the color and the standard board produce color difference, color mixing becomes very difficult, it is a waste of paint and color mixing is not accurate, at the same time, the paint can be opened very bad, and paint dry after the application of film color deviation and it is difficult to paint uniform

Water-based paint is also the first choice product when we decorate our homes, because its material is environmentally friendly and it is also very good for our decoration. But the material composition inside is also very particular, among which dispersant is indispensable. With it, our decoration will be more effective.

Commonly used dispersants include the following categories

Surfactant. Surfactants are composed of lipophilic and hydrophilic groups and are amphipathic molecules, including long-chain fatty acids, cetyltrimethylammonium bromide (CTAB), etc. The main function of this type of dispersant is the steric hindrance effect. The hydrophilic group is adsorbed on the surface of the powder and the hydrophobic chain extends into the solvent, which has a good effect on improving the rheology of the slurry. CTAB and dioctadecyldimethylammonium chloride (DDAC) can significantly improve the dispersion of bentonite in water.

The construction performance of refractory castables depends on its thixotropy and fluidity. In order to improve the fluidity of refractory castables, an effective measure is to increase water consumption.

Dispersant is a surfactant that has two opposite properties: lipophilic and hydrophilic in the molecule. It can be used to evenly disperse inorganic and organic solid particles that are difficult to dissolve in liquids. It can also be used to prevent the settling and agglomeration of solid particles. , forming a stable suspension. As a common chemical additive, dispersants have various functions such as dispersion, stabilization, and wetting. They are widely used in coatings, printing inks, medicine, cosmetics, agriculture, textiles, food and other industries.

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.

Dispersant is a common chemical additive that is widely used in chemicals in various fields and has various functions such as dispersion, stabilization, and wetting. It can disperse solid particles evenly in the liquid and avoid the aggregation and precipitation of particles in the liquid, thus improving the quality and stability of the product. The application range of dispersants is very wide. Let’s take a look at the functions and uses of dispersants.
