Fuhua precipitated barium sulfate is commonly used as a coating pigment in paper production. It is added to the surface layer of paper to enhance its opacity, brightness, and smoothness. The fine particles of barium sulfate fill in the gaps between fibers, creating a more even and reflective surface that improves printability and enhances the overall appearance of the paper.

Fuhua precipitated barium sulfate is also utilized as a filler in paper manufacturing. It is mixed with pulp fibers to improve the bulk and stiffness of the paper. The addition of barium sulfate helps to control the porosity of the paper, increase its weight and thickness, and provide a more substantial feel.

Fuhua precipitated barium sulfate acts as a brightening agent in paper production. Its high refractive index allows it to scatter light effectively, resulting in increased brightness and whiteness of the paper. This is particularly desirable for applications that require high-quality printing, such as magazines, catalogs, and glossy paper.

In some cases, precipitated barium sulfate can be used as a sizing agent in paper manufacturing. It helps to control the absorption of liquids, such as ink or dye, by the paper fibers. By applying a thin layer of barium sulfate onto the paper surface, manufacturers can improve the water resistance and ink holdout properties, leading to sharper print and reduced bleed-through.

Precipitated barium sulfate can also function as an anti-settling agent in paper coatings. It helps to prevent the settling of other pigments or fillers during the coating process, ensuring uniform distribution and improved color consistency throughout the paper.

By incorporating precipitated barium sulfate into the paper production process, manufacturers can achieve improved opacity, brightness, smoothness, printability, and overall quality of the paper products.
