is a dry, ground, powdered lignite used in water based muds.
TYPICAL PHYSICAL PROPERTIES:
Appearance Brown to black free flowing powder
pH (1% soln) 4.5
Bulk Density 99.8lb/ft³
Moisture Content at 105 # 2 ºC 12 % max
Lignite Powder is used in water based muds as a dispersant and fluid loss control additive especially at elevated temperatures and pressures. Lignite Powder is stable up to 400°F and may be used in all types of water based mud systems.
Lignite Powder is normally mixed through the hopper at the rate of 10-15 minutes per sack. Normal treatments are in the range of 3-8 ppb.
1. Physical state The material shall be in the form of powder, Free from lumps and visible impurities
2. Moisture Content at 105 # 2 ºC, 12.0 (Maximum)
3. Dry Screen Analysis:
Fraction Passing through 72Mesh BSS or 95(minimum)
Equigalent Sieve,Percent by mass
4. Performance Test:
(a) Preparation of Sodium Lignite Solution Take 50 g of 72 Mesh (BSS or Equivlent) Powdered Lignite (on dry basis) and dissolve in 350 ml of Distilled Water containing 10 g Caustic Soda (AR/GR grade) with the help of Hamilton Beach Mixer,stirring at high speed for 30 minutes. Transfer if to 500 ml volumetric flask. Age this Solutionfor
24 hours at 24 ± 2 ºc and make the volume to
500 ml. Mix the Solution thoroughly to make it Homogenous before use.
TOXICITY AND HANDLING:
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the Transportation and Material Safety Data Sheet (MSDS).
Lignite Powder is packaged in 25 Kg paper bags.
