Barite powder, barite powder grinding 325-3000 application value is reflected in where?
In some oil and gas well drilling, the general use of drilling mud, clay proportion is about 2.5, the proportion of water is 1, so the mud density is low, sometimes not mud weight and the underground oil and gas pressure balance caused by underground blowout accident. In the case of high pressure, it is necessary to increase the proportion of mud, increase effective measures to join the mud in the mud is barite. Do drilling mud with barite fineness to generally reached more than 325 mesh, such as barite insufficient fineness is prone to precipitation. Drilling mud with barite requirement is more than 4.2, BaSO4 content of not less than 95%, the soluble salt is less than 1%.
Application value of 325-2500 mesh barite powder in construction of road:The asphalt mixture containing about 10% rubber and barite have been successfully used in the parking lot, is a durable paving material. At present, heavy road construction equipment tires have been partially filled with barite, to increase the weight, to reinforce the embankment. Barite powder stone below 450 mesh, a proposal for PU Rui Raymond mill, 325 -3000 mesh, a PU Rui Machinery recommend ultra-fine powder mill.
In the paint industry, barite powder filler can increase the film thickness, strength and durability. Lithopone pigments are used in the manufacture of white paint, indoor use has more advantages than the white, white paint. The whiteness of magnesium industrial barite is of sufficient fineness and high.
