High cost performance: Precipitated barium sulfate has an extremely high reflectivity in a wide spectrum, so it looks like a white powder and is color neutral. This can maintain the original brightness and hue of the pigment. Most pigments are prone to form agglomerates, which will weaken the coloring power of the pigment.
Can reduce solvent content: Precipitated barium sulfate has low oil absorption, which can effectively increase the solid content of the color paste and reduce the amount of solvent. It has almost no effect on viscosity and reduces VOC.
Very good weather resistance/chemical resistance: Precipitated barium sulfate has strong light reflection ability in the ultraviolet wavelength range, and can cooperate with TiO2 to have good sun resistance and weather resistance.
Improve mechanical properties: The coating with added precipitated barium sulfate has better interlayer adhesion and film hardness.
Application of Precipitated Barium Sulfate
PCB Ink: It is widely used in PCB ink. As a functional filler, it has the characteristics of small particle size, inorganic coating on the surface of the product, and good dispersion. The printability, coverage, leveling, and anti sagging properties of solder mask ink for circuit boards have been significantly improved.
Coatings: It is widely used in coatings. The product has high whiteness, low oil absorption, good dispersibility, and can increase the glossiness and color rendering of the paint.
Plastic: It is widely used in plastics. It can improve the impact and rigidity of plastics, reduce shrinkage, enhance dimensional stability, and strengthen the wear and corrosion resistance of plastics.
Chemical Fibers: It has important applications in the field of chemical fibers. The CH Series Modified Precipitated Barium Sulphate undergoes special inorganic and organic coating treatment, resulting in high whiteness, no impurities, uniform and narrow particle size distribution, excellent dispersibility, and no secondary agglomeration.
Film (BoPET): It has important applications in polyester films (BoPET). Due to the fact that the refractive index of AB Series Modified Precipitated Barium Sulphate is almost the same as PET, it does not affect the transparency of the film.
Lithium Ion Battery Separator: It plays an important role in lithium-ion battery separators and can be used as a ceramic coating agent for separators. On the one hand, it can significantly enhance the mechanical properties of the separator, making it less prone to rupture under external compression, impact, and other conditions, providing reliable physical protection for the battery and greatly improving its safety.

Production Method of Precipitated Barium Sulfate
Crushing: The barite and raw coal are crushed by a crusher and stored in a raw material bin of coarse barium.
Grinding: The fuel coal is crushed and conveyed to the Raymond machine for grinding. The qualified coal powder is then sent to the coal powder combustion system of the coarse barium rotary kiln and the blower also sprays the powder to the converter for combustion.
Calcination: The crushed barite and coal powder enter the rotary kiln for a reduction reaction to make coarse barium sulphide.
Leaching: The coarse barium sulphide prepared by the coarse barium rotary kiln is poured into the leaching tank with a crane, then the dilute barium sulphide solution and the filtered mother liquor from the drying section are leached to obtain the barium sulphide solution.
Nitrate: A certain amount of barium sulphate wastewater (dilute sodium sulphide solution) is placed in the nitrate tank and heated to above 40°C with steam. Start the mixer, input the sodium sulphate into the tank, and continue to heat up to 90°C. After removing magnesium and calcium by sodium sulphide, the mass concentration of nitrate water is controlled at 1.1995-1.2198 kg/L and finally input into the clarification tank for backup.
Compounding: After clarifying the above two solutions, they are put into a compound tank in a certain proportion for metathesis reaction. The obtained barium sulphate slurry is then subjected to liquid-solid separation by a centrifuge, and the separated filter cake enters the drying system.
Drying: Barium sulphate filter cake is then dried, graded, and packaged after stirring and crushing by the feeder.
