Буровая Барит (плотность-4,2-сетка 325)

Barite is a very important non-metallic mineral raw material, with a wide range of industrial uses. (1) increase the drilling mud agent: In some wells, gas well drilling, the general use of the drilling mud, clay, accounting for around 25, the proportion of water to 1, so the lower the proportion of mud, sometimes mud weight can not be underground oil and gas pressure balance, causing blowout. In the ground under high pressure, the need to increase the proportion of mud, barite powder added to the slurry is an effective measure to increase the proportion of mud. Barite used in drilling mud to do the general fineness of 325 or more to achieve, such as the fineness of barite precipitation is easy enough. Requirements with the barite drilling mud weight is greater than 4.2, BaSO4 content of not less than 95%, less than 1% of soluble salts. (2) Zinc barium white pigment; to barite barium oxide as raw material to manufacture, barium carbonate, barium chloride, barium nitrate, barium sulfate precipitation, barium hydroxide and other chemicals. (3) 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, for indoor use than lead white, magnesium white has more advantages. Paint industrial barite requires sufficient fineness and high whiteness. (4) Cement raw materials, road construction. (5) Reconciliation of barite and oil applied to cloth to create linoleum. (6) Barite powder for refined kerosene. (7) In the pharmaceutical industry to do gastrointestinal contrast agent. (8) Pesticides, leather, manufacturing fireworks, etc. (9) Barite used to extract metals barium, for television and other vacuum tube getter, binder (10) Barium and other metal (aluminum, magnesium, lead, calcium) made of alloy for bearing and brake manufacturing.

Barite powder is mainly used for oil, chemicals, paints, fillers and other industrial sectors, of which 80% -90% for oil drilling project, suitable for oil and gas wells in the circulation rotary drilling mud weighting material, cooling the bit, cut down and taken away debris material, lubricating the drill pipe, closed cell wall, gas pressure control to prevent the oil from the jet functions. The mentioned data of analysis just for reference, the actual result depends on physical material loaded. As natural mineral products, the mentioned product is food grade with non-toxic, harmless, non-smell, it is safety in transportation and the se of the process, and it has no any harm to person. Personal Precautions: Avoid breathing dust. Wear respirator when airborne dust is present Harmful by Inhalation Danger of serious damage to health by prolonged exposure
