There are many defects in the traditional production process of precipitated barium sulfate, and timely revision of the product process can improve resource utilization, reduce enterprise production costs, and improve product quality. n silane coupling agent is inseparable from ultra-fine barium sulfate. The precipitation of barium sulfate in most of the chemical raw materials is a common one, which makes people begin to understand and use it. Just like the silane coupling agent, it is also an indispensable raw material for the production of plastics, but how can these two products be better combined to use? Expand the production specific gravity of precipitated barium sulfate to protect the natural environment. The inorganic industry of precipitated barium sulfate is used to produce other barium salts such as barium hydroxide, barium carbonate, and barium chloride as raw materials. It is used to make primer and modulate printing paint in the production of wood-grain printing boards in the wood industry. In the synthesis, it is used as green pigment and lake to produce physical printing and ink filler, which can be resistant to aging and exposure to sunlight. During the production process, the particle size can be controlled (D50 is above 0.3μm). The crystal shape of the particles is approximately spherical, and the finished product has a high degree of smoothness and better weather resistance after film formation. Precipitated barium sulfate has the advantages of strong chemical inertness, good stability, acid and alkali resistance, moderate hardness, high specific gravity, high whiteness, and ability to absorb harmful rays. It is an environmentally friendly material, so it is widely used in various coatings. In the fields of printing ink, synthetic chemical industry, rubber, papermaking, ceramics, etc. The traditional barium sulfate is limited by the production process.
