Barite powder in the chemical production of raw materials in the field of the nature and use
of
1. Introduction

Barite powder is an important non-metallic mineral resources, widely used in chemical, petroleum, pharmaceutical, building materials and other fields. In the field of chemical production raw materials, barite powder has attracted much attention because of its unique properties and uses. This article will detail the properties of barite powder and its use in the field of chemical production raw materials.

2. the nature of barite powder

1. physical properties: barite powder is white or slightly light yellow, light gray powder, with glass luster, density, Mohs hardness of 3-3.5, brittle.
2. Chemical properties: Barite powder is mainly composed of barium sulfate (BaSO4), which has high chemical stability and acid resistance, and is insoluble in water, acid, alkali and organic solvents.

3. barite powder in the chemical production of raw materials in the field of use

1 plastic filler: barite powder can be used as plastic filler, improve the hardness of plastic, rigidity and heat resistance, while reducing production costs. In polyvinyl chloride (PVC) and other plastics, the addition of barite powder can significantly improve its processing performance and performance.
2. Paint: Barite powder has excellent hiding power and weather resistance, can be used as a body pigment in paint coatings to improve the hiding power, weather resistance and leveling of the coating.
3. Rubber products: In rubber products, barite powder can be used as a filler to improve the hardness and wear resistance of rubber, while reducing costs.
4. Ceramic products: barite powder can be used as raw materials for ceramic products to improve the density and mechanical strength of ceramics.
5. Glass products: In glass products, barite powder can be used as a fining agent to improve the transparency and mechanical strength of glass.

4. barite powder production process

barite powder production process mainly includes crushing, grinding, grading and packaging steps. First, the barite raw ore is crushed, and then ground to achieve a certain degree of fineness. Then, the barite powder of different particle size is separated by the classification equipment, and finally packaged. In the production process, it is necessary to strictly control the process parameters of each link to ensure the quality and stability of the product.

5. barite powder market prospects

With the continuous development of science and technology and people's growing demand for high-performance, high-quality chemicals, barite powder in the field of chemical production of raw materials in the application prospect is very broad. In the future, with the continuous emergence of new technologies and new materials, the performance and application of barite powder will be further expanded. At the same time, with the continuous improvement of environmental awareness and the increasing shortage of resources, the green production and resource utilization of barite powder will become the future development trend.

6. conclusion

In short, barite powder as an important raw material for chemical production has a wide range of applications and good market prospects. In the future development, we should strengthen technology research and development and promotion, improve the utilization rate and added value of barite powder, promote its green production and resource utilization, and contribute to the sustainable development of the chemical industry.
