Uses of precipitated barium sulfate

Precipitated barium sulfate is a chemical raw material. Calcium, magnesium and other solutions are added to the barium sulfate solution and mixed, and then reacted at about 80 degrees. At this time, a precipitate will be generated. After filtration, water washing and acid washing, the PS value can reach between 5 and 6. After filtering, drying, crushing and other corresponding processes, the use of precipitated barium sulfate is also relatively wide.

Uses of precipitated barium sulfate

Glass products are used as clarifiers to remove bubbles and increase gloss. It can be used as a protective wall material to prevent radiation. It is also used in industries such as ceramics, enamel, spices and pigments. It is also the raw material for manufacturing other barium salts - powder coatings, paints, marine primers, military equipment paints, automotive paints, latex paints, interior and exterior wall architectural coatings. It can improve the product's light resistance, weather resistance, chemical and electrochemical corrosion resistance, product decorative effect, and enhance the impact strength of the coating. In the inorganic industry, it is used as raw material for the manufacture of other barium salts such as barium hydroxide, barium carbonate, barium chloride, etc. It is used for priming and preparing printing paints when producing wood grain printing boards in the wood industry. Used as a filler in the production of green pigments and color lakes in organic synthesis.

1. Printing

Ink filler can resist aging and exposure, increase adhesion, make the color clear, bright and non-fading.

2. Filling

It can enhance the anti-aging and weather resistance of tire rubber, insulating rubber, rubber sheet, tape, and engineering plastics, making the products less prone to aging and becoming brittle, and can significantly improve the surface finish and reduce production costs. As the main filler for powder coatings, it is the main means to adjust the powder bulk density and increase the powder coating rate.

3. Functional materials

Papermaking materials (mainly paste products), flame retardant materials, X-ray protection materials, battery cathode materials, etc. They can all exhibit unique properties and are important and indispensable components of related materials.

4. Other fields

The compounding of ceramics, glass raw materials, special resin mold materials, precipitated barium sulfate with special particle size distribution and titanium dioxide has a synergistic effect on titanium dioxide, thereby reducing the dosage of titanium dioxide.

It is used as a raw material or filler for paints, inks, plastics, advertising pigments, cosmetics, and batteries. It is used as a filler and reinforcement in rubber products. It is used as a filler and weighting agent in polyvinyl chloride resins. It is also used as a surface coating agent for printing paper and coated paper, and a sizing agent for the textile industry.
