Advantages of Superfine Barium Sulfate
The fullness of the coating can be enhanced
After the use of ultrafine barium sulfate, a very smooth and glossy surface is formed on the surface of the paint, making it better fluidity and enhanced leveling in the coating addition. Add paint base material with ultra-fine barium sulfate showed non Newtonian viscosity, liquidity and can improve the coating, prevent sagging, prevent precipitation, make the film with good fullness.
With a better dispersion
In the coating base, the dispersibility is good under the usual dispersing condition of the pigment. Therefore, the use of added to the pigment coating, coating formed, whitening phenomenon will occur due to the light scattering of barium sulfate.
High transparency in resin liquid
As we all know, the visible light wavelength is 380-780 nm, if the diameter of 0.19 microns, the half wavelength light you can see the following, light can pass this particle. The average particle size of this superfine barium sulfate is 0.01~0.08 micron, and the particle size distribution is very narrow.
Coatings and paint industry: It can be used as a filler for paints and coatings instead of precipitated barium sulfate, lithopone, titanium dioxide, active silica and other relatively expensive raw materials. It is suitable for controlling the viscosity of paint and making the product bright and stable it is good.
Plastic industry: It can be used as a filler for plastic ABS raw materials to make the product shiny and bright, and it can also improve the product's strength, rigidity and wear resistance.
Cement industry: Compound mineralizers such as barite, fluorite and gypsum.
Construction industry: Used as concrete aggregates, paving materials, heavy pressure on buried pipelines in swamp areas, instead of lead plates used for shielding in nuclear facilities, atomic power plants, X-ray laboratories, etc., to extend the life of road surfaces.

Production Method of Superfine Barium Sulfate
Reacting a barium sulfide solution (140 g/l) with a sodium sulfate solution (310g/l) to generate a barium sulfate solution and a sodium sulfide solution, precipitating and clarifying the generated sodium sulfide solution, cooling a part of the sodium sulfide solution to 40 ℃, and pumping the cooled sodium sulfide solution into an air blowing device. Blowing air in an air blowing device for 5 hours, filtering, dissolving a sodium sulfate solution with hot water, and blending the sodium sulfate solution to 310g/l after removing calcium and magnesium, wherein the concentration of the filtered sodium sulfide solution is 46.86 g/l; after the filtered sodium sulfide solution is reused in a sodium sulfate solution, the concentration of the sodium sulfate solution is 130g/l, the solution is combined with a barium sulfide solution (140 g/l) to react to generate a barium sulfate solution and a sodium sulfide solution, the reaction solution is filtered to separate the barium sulfate solution and the sodium sulfide solution.
Reacting the barium sulfide solution (140 g/l) with the sodium sulfate solution (310g/l) to generate a sodium sulfide solution with the concentration: 46.86g/l of the total weight of the oil, the particle size of barium sulfate is d50:1.28 μm and d90:2.84 μm; after the sodium sulfide solution is reused in the sodium sulfate solution, the concentration of sodium sulfide is as follows: 27.21 g/l.
The sodium sulfate solution of the recycled sodium sulfide solution reacts with the barium sulfide solution to generate barium sulfate and sodium sulfide solution, the generated barium sulfate has small particle size, high whiteness and good quality, the concentration of the sodium sulfide solution is not changed greatly, and the subsequent production of 60 alkali (the content of sodium sulfide is 60%) is not influenced.
