How to detect the quality and purity of precipitated barium sulfate


There are two types of barium sulfate: high temperature calcined spar powder and chemically synthesized precipitated barium sulfate. Natural barium sulfate refers to barite powder obtained by grinding barite, also known as barium sulfate. Barium sulfate and calcined barium sulfate have different barium content.


How to distinguish the quality of the product when purchasing precipitated barium sulfate? This depends on the purity of the products processed by the precipitated barium sulfate manufacturer. In addition, the difference in the production process of precipitated barium sulfate is also related to the purity of the precipitated barium sulfate. Pure, the better the effect in the application, so in order to ensure the performance of precipitated barium sulfate, we must pay attention to the product purity of precipitated barium sulfate, how to distinguish the product quality of precipitated barium sulfate, let's take a look together.


Precipitated barium sulfate is widely used in spray paint and top paint, because it has the characteristics of uniform particle distribution, high whiteness, low cohesion, etc., so we will feel the paint surface is more delicate and good gloss after spraying the paint. , Make the effect after spraying due to other products. Because precipitated barium sulfate is insoluble in water and has strong corrosion resistance, the surface sprayed under long-term exposure to the sun is not easy to deteriorate, and the color is relatively stable, which increases the service life.


Precipitated barium sulfate can also be used as a filler in paint and used in the ship and automobile industries. This is when we require thicker spray paint to increase wear resistance and protect the primer inside from being damaged. Such a wide range of applications has made it a very good reputation in the paint industry. High purity, few impurities, no trace of ore and salt impurities (no corrosion or sulfide components), bubbling phenomenon such as no reaction when meeting acidic materials. Highly inert chemical substances, acid and alkali resistance, good sun resistance and weather resistance. Narrow particle size distribution, small specific surface area and base material consumption, high pass rate, high gloss and fluidity, reliable fineness. It has good compatibility with the matrix, close combination, and is not easy to fade. Good dispersion and good covering effect.
