Can be used for products in contact with food, superfine barium sulfate only acts as a filler. It doesn't sound good. It is used to reduce costs. As long as the things you add have no effect on the paint film, performance and storage stability, add them. The dosage needs to be re-examined. The oil absorption capacity of each filler is different. Yes, it may affect the gloss of the paint film and the viscosity of the paint. Ultrafine barium sulfate refers to the use of natural barium sulfate to produce precipitated barium sulfate after chemical reaction, and then stearic acid is added to precipitated sulfuric acid. barium to modify the activity of barium sulfate. Modified barium sulfate is mainly used as special functional filler material. It is suitable for powder coating, material, ink and plastic products. It has strong affinity and sex, and natural barium sulfate is barite ore. It is processed by beneficiation, washing, crushing and other processes, with moderate hardness. Brittle, chemically stable, insoluble in water, ethanol and hydrochloric acid.

Moreover, the investment of such equipment is relatively low, and the operating cost is relatively low, which is very suitable for some small and medium-sized mineral processing manufacturers to use. Barium sulfate is processed by natural barium sulfate beneficiation, ore washing and crushing. The barium sulfate product has high purity, and the impurities in it are relatively small. And also has better gloss, such a good appearance can have better dispersion.
