Yuanlei Classroom | As a key material, how many applications does precipitated barium sulfate have?

The appearance of precipitated barium sulfate is a white amorphous powder, with a relative density of 4.50 (15 ℃) and a melting point of 1580 ℃. Due to its high refractive index (1.63-1.65), it exhibits a relatively white color and a certain degree of covering power. It is almost insoluble in water, ethanol, and acid, soluble in hot sulfuric acid. It is easy to form mixed crystals with potassium permanganate, calcium carbonate, or metal nitrates, and can be reduced to barium sulfide with carbon at high temperatures.

Precipitated barium sulfate is an important basic chemical raw material, mainly used as a raw material or filler for paints, coatings, inks, plastics, rubber, and batteries;
1. Surface coating agents for image paper and copperplate paper;
2. Sizing agents used in the textile industry;
3. As a clarifying agent in glass products, it can play a role in defoaming and increasing luster.
4. It can also be used as a protective wall material for radiation protection, and is also used in industries such as porcelain, enamel, and dyes. It is also a raw material for manufacturing other barium salts.
5. Used as a raw material or filler for paints, inks, plastics, advertising pigments, cosmetics, and batteries. In rubber products, it serves as both a filler and a reinforcing agent.
6. Polychloroethane resin is used as a filler and weight enhancer, as a surface coating agent for printing paper and copperplate paper, and as a sizing agent for the textile industry.
7. Can be used as a protective wall material for radiation protection.
8. It is also used in industries such as ceramics, enamel, spices, and pigments.
8. It is also a raw material for manufacturing other barium salts - powder coating, paint, marine primer, military equipment paint, automotive paint, latex paint, interior and exterior wall building coatings. It can improve the product's light resistance, weather resistance, chemical and electrochemical corrosion resistance, and decorative effect, enhancing the impact strength of the coating.
9. Inorganic industry is used as a raw material for manufacturing other barium salts such as barium hydroxide, barium carbonate, barium chloride, etc.
10. When producing wood grain printed boards in the wood industry, they are used as a base and to prepare printing paints.
11. In organic synthesis, it is used as a filler for the production of green pigments and lakes.

Printing - Ink fillers can play a role in aging resistance, sun resistance, increased adhesion, clear color, brightness, and non fading.

Filler - tire rubber, insulating rubber, rubber plate, tape, and engineering plastics can enhance the anti-aging performance and weather resistance of the product. The product is not easy to age and become brittle, and can significantly improve the surface finish, reduce production costs. As the main filler of powder coatings, it is the main means to adjust the bulk density of powder and improve the powder loading rate.

Functional materials - papermaking materials (mainly used in paste products), flame retardant materials, X-ray resistant materials, battery cathode materials, etc. They can demonstrate unique performance and are an indispensable and important component of related materials.

In other fields, such as ceramics, glass raw materials, special resin mold materials, and the combination of precipitated barium sulfate with titanium dioxide with special particle size distribution, it has a synergistic effect on titanium dioxide, thereby reducing the amount of titanium dioxide used.

Wet mica powder is a high-quality mineral filler made from high-quality mica raw materials, which are washed, impurity removed, soaked, crushed, low-temperature dried, and screened. Its unique production process maximizes the preservation of mica's sheet-like structure, large diameter to thickness ratio, high refractive index, high purity, high whiteness, high gloss, low sand and iron content, and other industrial characteristics that cannot be compared to dry process technology. The unique performance of wet mica powder has greatly improved its application in multiple industries such as plastics, paint, rubber, etc., and has a significant effect on improving product performance and reducing costs.
