Shanghai Tengmin Industry Barium sulfateTM1250

Shanghai Tengmin Industry Barium SulfateTM1250 is a white to fine powder, odorless and tasteless. Decomposes above 1600 ℃. Soluble in hot concentrated sulfuric acid, almost insoluble in water, ethanol and dilute acid. Barium sulfate has plate-like crystals, complete cleavage with close angle intersections, specific gravity 4.0-4.6 , foaming when exposed to hydrochloric acid cloth, strong chemical inertness, and good stability. Good barium sulfate has high reflectivity and can absorb harmful rays. , Is a kind of material with environmental protection function.

Application
  • Petroleum : The circulating mud weighting agent in the rotary drilling of oil and gas wells cools the drill bit, removes the cutting debris, lubricates the drill pipe, seals the hole wall, controls the oil and gas pressure, and prevents the oil well from spontaneous blowout.　　
  • Chemical Industry: production of various barium compounds such as barium carbonate, barium chloride, barium sulfate, lithopone, barium hydroxide, and barium oxide.
  • Filler : In the aspect of paint , it can also be added as an extender pigment to the paint, which can improve the covering and compactness of the paint and film. Improve the performance of the coating to a certain extent.

Technical Details & Test Data

Test Methods
  • Average particle size: the median value of the cumulative weight percentage of the particle size distribution measured by the laser particle size analyzer Ls-pop
  • 325 mesh surplus: use the wet method to filter the sample on a 325 mesh surplus, and calculate the residual ratio
  • Whiteness: measured by DN-B photoelectric whiteness meter
  • Oil absorption: JIS-K5101 method, measured when adding linseed oil to lumps
  • Moisture: Oven drying method
