Glossiness: If the gloss of the paint is to be high, the particles contained in it should not be larger than 5 microns, and the ink should not even be larger than 1 micron. Polymer dispersants can reduce the large particles formed in the paint and help the paint improve its gloss.

What is carbon black? Carbon black (also called carbon black) is a colloidal particle similar to a sphere formed by incomplete combustion or thermal cracking of hydrocarbon compounds (liquid or gaseous). It exists in the form of aggregates and appears as pure black powder or granular. The particle size, structure and surface activity of products vary greatly depending on raw materials, manufacturing methods and production processes. The main component of carbon black is carbon, and also contains trace amounts of hydrogen, oxygen, ash and moisture.

The determination of the added amount usually requires consideration of the following factors: Type and quality of carbon black: Different types and qualities of carbon black may require different amounts of Dongfugui dispersant. For example, the amounts of low-pigment carbon black, high-pigment carbon black, and conductive carbon black are completely different.

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.
