Yuan Lei tells you | The main use of high-gloss barium sulfate


High-gloss barium sulfate is barite ore, processed by beneficiation, ore washing, crushing and other processes. Moderate hardness, brittle, stable chemical properties, insoluble in water, ethanol and hydrochloric acid, acid and alkali resistance and water resistance.

The main characteristics of high gloss barium sulfate are good dispersion, high whiteness and good leveling. It has excellent light resistance, weather resistance and acid resistance, good chemical inertness and moderate surface energy, making it a functional filler with good dispersion and affinity with other media. And with all the pigment has good compatibility, can replace part of the precipitated barium sulfate, titanium dioxide, active silica and other high-priced raw materials, reduce costs. It is an environmentally friendly material that can absorb harmful rays and works well in powder coatings.


The main use of high gloss barium sulfate:



Used in plastics, with good dispersion, can enhance the hardness and rigidity of the plastic, maintain the surface gloss and brightness of the plastic, especially suitable for the manufacture of high-gloss home appliance shells PP and nylon parts.



Application in the coating, the product and titanium dioxide according to a certain proportion of the use of at the same time, can make titanium dioxide more effectively play its cover performance, reduce the amount of titanium dioxide, especially suitable for automotive paint, high-grade exterior wall coatings. At the same time, there is a significant improvement in anti-chalking performance.


powder coating

Applied to powder coatings, powder coatings can enhance the leveling and gloss retention, and have good compatibility with all the pigments, can improve the powder coating in the spraying process to achieve the most ideal film thickness, improve the powder rate, reduce the amount of powder coating, powder coating on the grade of the required products.



Barium sulfate used in coatings and paints, the fineness is generally325The purpose,800The purpose,1250More purpose. Especially in the coating requirements are relatively fine, mostly used1250The purpose is more. Under normal circumstances, the barium sulfate will be crushed1-8μmParticle size, applied to latex paint can replace part of the titanium dioxide, while the whiteness and hiding power did not decline.


In some coatings, such as electrostatic spraying, we need is gloss, as long as the gloss can be done, the effect of the coating is obvious. Therefore, the requirement for barium sulfate is to improve the gloss of the coating.

Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.
