First of all, what is nano-barium sulfate?

Barium sulfate is a kind of inorganic chemical raw material with high specific surface area, high activity and good dispersion. It is widely used in coatings, plastics, paper, rubber, ink pigments and other fields.

Nano-barium sulfate in plastic

In the plastics industry, nano-barium sulfate can be added to the polymer to obtain a composite material with high strength and high toughness. However, it should be noted that the amount of nano-barium sulfate and surface modifier will have an impact on the mechanical properties of the composite material. Excessive amount will cause multi-layer physical adsorption on the surface of nano-barium sulfate and serious agglomeration phenomenon, while too little amount will increase the interface defects between nano-barium sulfate and the polymer, resulting in a decrease in the mechanical properties of the composite material.

Application of nano-barium sulfate in coatings

In the coating industry, nano-barium sulfate can be used as a physical pigment, which can improve the thickness, wear resistance, water resistance, heat resistance, surface hardness, impact resistance and so on. Its characteristics include fine particle size, narrow particle size distribution, transparent dispersion in resin liquid, good dispersion in paint base material, and organic coloring pigments with dispersion AIDS, can improve physical properties.

Characteristics of nano-barium sulfate for coating:
1. Ultra-fine particle size and narrow particle size distribution
2. High transparency of resin liquid
3. Good dispersion in the substrate
4. Better dispersion when used with organic pigments
5. Excellent mechanical properties

Nano-barium sulfate in paper making

Barium sulfate has good physical and chemical stability, medium hardness, high whiteness and the ability to absorb harmful rays, making it an ideal filler for the paper industry. For example, copy paper is common in school and office supplies, but its surface is prone to discoloration. Therefore, it is necessary to have a barium sulfate filler with a high oil absorption value, which can improve the ink absorption of copy paper. And because the particle size of nano-barium sulfate is small and uniform, it can make the paper more flat and wear the machine less.

Newly applied nano-barium sulfate
