Barite Raymond Mill

Barite powder is a kind of important inorganic barium-containing mineral raw materials, there is a big difference between the nature of polymer materials, the lack of affinity for its application in the field of polymer materials is limited. To further improve its performance and broaden its applications, must barite powder surface modification treatment. This paper discusses the method of Raymond mill barite surface modification and application, in order to promote barite powder application development. Powder surface modification technology in China in the twentieth century, 80 years before the technology developed. At present, the domestic non-metallic mineral ultra-fine powder of the increasing demand and development, in which the kaolin, calcium carbonate, talc, graphite powder modified more research and application development, but a change of barite research and application development is relatively small. Study abroad barite powder surface modification of the twentieth century began in the 1970s, but in our late start. Barite has a wider industrial use and deep processing of high value-added, and therefore, should be modified and applied research and development of strong barite powder, barite expand the application fields. Barite is an important mineral containing barium, with density, chemical stability and thermal properties and other characteristics, and its main industrial application areas are oil and chemical industries. In the oil industry, mainly used for oil and gas drilling mud weighting agent; in the Raymond mill industry, with barite as raw materials for the manufacture of various chemical products containing barium, such as barium carbonate, barium sulfate, barium oxide, lithopone (lithopone). In the paint industry, barite powder filler may increase the film thickness, strength and durability. Lithopone white pigment used in the manufacture of paints, indoor use than zinc white, lead white has more advantages. Paint for industrial use of barite desired particle size 2μm content and whiteness greater than 90%; in the rubber and plastics industry, with barite as filler, can improve the rubber and plastics hardness, wear resistance and resistance to aging. Because barite has a special character and cheap development costs, they are increasingly subject to people's attention. The development of modern industry, the barite purity, whiteness and particle size have put forward higher requirements. Thus, with the deepening development of science and technology and research, more performance barite will be revealed. Barite deep processing such as superfine splintered, purification, surface modification, not only can broaden the application areas, and better economic returns, there is a greater demand in the domestic market. However, inorganic mineral powder material with an organic polymer in the chemical structure and physical form there are significant differences between the two different surface properties, leading to its compatibility and affinity have a greater difference. When the barite used as a filler, is difficult to uniformly dispersed in an organic polymer and affect the mechanical properties of composite materials, and difficult to play functionality, surfactants and other fine features and small size inorganic fillers. Therefore, barite powder surface modification, you can choose a suitable surface modifier applied to barite, improve physical and mechanical properties of the modified materials, so that barite powder have a wider application.
