Product Features and Applications
Ultrafine barium sulfate is a colorless orthorhombic crystal or white amorphous powder. The relative density was 4.50 (15 ºC). Melting point 1580 ºC. It is almost insoluble in water, ethanol and acid. Soluble in hot concentrated sulfuric acid, easy to agglomerate when drying. Barium sulfide can be reduced by carbon at 600 ºC. The application of barium sulfate in paint is better than most other filling powder, with low cohesiveness, low light dispersion and fine particles. It is especially suitable for pigment topcoat, varnish and spray paint, with chemical resistance and weather resistance.
The higher the melting point of precipitated barium sulfate is, the better it will play in the product processing and smelting. The application of precipitated barium sulfate is colorless orthorhombic crystal or white amorphous powder. The relative density was 4.50 (15 ºC). Melting point 1580 ºC. It is almost insoluble in water, ethanol and acid. Soluble in hot concentrated sulfuric acid, easy to agglomerate when drying. Barium sulfide can be reduced by carbon at 600 ºC.
Superfine barium sulfate is insoluble in water, acid, alkali and other organic intermediates, excellent gloss and particle fineness make the topcoat maintain long-term exposure. Barium sulfate is recommended for topcoat, which can increase surface hardness and color stability. Barium sulfate has high filling property, which can be applied to all kinds of coating series, such as primer, thick paste coating, etc. its low specific surface area, particle size distribution and easy fluidity make barium sulfate have low wear resistance in the process of processing. Barium sulfate is recommended to be used for automatic primer surface layer, and even maintains good uniformity and smoothness even at high filling.
Superfine is used as raw material or filler of paint and ink. It has excellent dispersibility in all paints. It can prevent the paint from agglomerating, improve the quality of paint and increase the fluidity. Surface coating agent for printing paper and copper paper, sizing agent for textile industry. Glass products can be used as clarifier to remove foam and increase luster. It can be used as a protective wall material against radiation. It is also used in ceramic, enamel, perfume and pigment industries. It is also a raw material for other barium salts.
Superfine barium sulfate has the advantages of strong chemical inertia, good stability, acid and alkali resistance, moderate hardness, high specific gravity, high whiteness, and can absorb harmful rays. It is a material with environmental protection function. Precipitated barium sulfate manufacturers are widely used in various coatings, medium and high-grade inks, pharmaceutical synthesis, rubber, papermaking, ceramics, cosmetics and other fields. Refined barium sulfate is widely used in all kinds of coatings (water-based, oil-based and powder coatings), ink, paper-making, engineering plastics (household appliances, building materials plastics), high-grade electrical insulation plastics, rubber products, etc. Application of barium sulfate in five industries
1. the use of barium sulfate in industrial industry
Application: used in rubber, plastic, paint, chemical industry as strengthening and upgrading filler.
Features: increase the stability of the product industry, increase the tensile strength, shear strength, bending strength, pressure strength, reduce deformation, elongation, thermal expansion coefficient, high whiteness. The particle size is uniform and the dispersion is strong.
2. the effect of large-scale use of ultrafine barium sulfate in ceramic industry
Application: used for manufacturing high frequency porcelain, wireless electric porcelain, various industrial ceramics, architectural ceramics, household ceramics, etc.
Features: high temperature does not change color, after calcination, whiteness is enhanced, density is uniform, luster is good, surface is smooth.
3. the application of nano barium sulfate in cosmetics industry
Application: it is a high quality filler for cosmetic industry.
Features: it contains a lot of silicon. It has the function of blocking infrared rays, thus enhancing the sunscreen and anti infrared properties of cosmetics.
4. the use of radiation proof barium sulfate in medicine and food
Application: used as additive in medicine and food industry.
Features: it has five poisons, tasteless, high whiteness, good tolerance, strong gloss, soft taste and strong smoothness. The pH value is 7-9, which will not degrade the characteristics of the original product.
5. the application of high gloss barium sulfate in papermaking
Application: used in various high and low grade paper industry products.
Features: high whiteness of paper powder. The particle size is stable and the wear degree is low. The paper made with this powder can achieve smooth and delicate paper, save raw materials and improve the service life of the resin mesh.
