Precipitation barium sulfate

Molecular formula: BaSO4
Weight: 233.40 (in 1979 the international atomic weight table)
Characteristics:
No qualitative white powder. Non-toxic, insoluble in water, dissolved in smoke sulfuric acid, hydrochloric acid-soluble in boiling. Chemical properties of stability, and a total reduction of carbon sulfide barium. In the case of hydrogen sulfide in the air or toxic gases do not change color.

Use:
Used as paint, ink, plastic, rubber and batteries of raw materials or filling machines, printed papers and copper coating on the surface of paper, textile and industrial use of the sizing agents. For clarification of glass products, from anti-foaming and to increase the role of gloss. Anti-radiation can be used as a protective wall material. Also used in ceramics, enamel, spices and paint industries. Barium salt manufacturers are also other raw materials.

High-barium

High-barium through a special chemical synthesis process, using special filtering technology and special surface treatment technology from the production, with white, no black particles, the dispersion of good characteristics. Ben Pinwei white powder-like material, non-toxic, tasteless, do not dissolve in water, acid and alkali and organic solvents, only dissolved in hot concentrated sulphuric acid, gas and any reaction. So is weathering, decay resistance excellent products.
Head products at 1250, 3000 Head, 5000 Head, 6000 head, 12,500 head, 15,000 head six specifications.
1, white, and the use of titanium white coordinating role.
2, small particles uniform, narrow particle size distribution, and imports of titanium white close.
3, a special surface treatment, decentralization and good, with high affinity resin.
4, in isolation from the titanium dioxide particles between the role of titanium dioxide particles to each other -
A certain distance, give full play to the performance of titanium white, to cover increased efficiency.
5, pure products, non-black particles to ensure purity of the products.
Use:
1, plastics, has a good dispersion, can enhance the hardness and rigidity of plastic, keep the surface shiny plastic and brightness, especially for household electrical appliance manufacturers in the case of high-PP and nylon parts.
2, powder coating, powder coating to enhance the flow-and-light, and with all the pigment has good compatibility.

Extinction barium
Barium with extinction following special features:
1, the extinction of the dispersion of barium good, played the greatest Zhegai Li, at the same time as the carrier of paint pigment dispersion and efficient access to uniform color, high-purity of the whiteness of the bright colors more pure; fine crystal structure and characteristics of high refractive index So that the rich color even more full.
2, extinction barium good chemical inertia, so that all types of systems to maintain the basic stability of the environment; ultra-fine particles to the surface strong, compatibility, and with other cross-organic composite materials, enhance the combined force; evenly dispersed differential monomer, stability Suspended in the system, no flocculation or precipitation.
3, the extinction of the high-density barium, bringing good wear resistance; ultra-fine particles can film with strong surface of the substrate more secure uniform ultrafine particles. The film even more smooth and more durable.
4, the extinction of barium fine chemical inert, waterproof acid and resistant to acid rain, heat and corrosion-resistant, but also has a special-ray absorption, greatly enhance the weathering of the paint.
Use:
1, used in the coatings, paints, extinction barium can be used as paint, paint filler alternative precipitation barium sulfate, lithopone, titanium dioxide, silica activity, such as higher prices of raw materials, paints for control of viscosity, color products Bright, good stability.
2, for the Plastics Industry, the extinction of barium can be used ABS plastic packing materials, can also be used for chips and mahjong, shiny-edge products, and can also improve product strength, stiffness and wear-resistant. 3, for the rubber industry, the extinction of barium as a filler, to reduce costs and improve products hardness, Naisuan Jian and water resistance, and natural rubber and synthetic rubber have a good reinforcement role.
