Polyanionic cellulose.

Rosfloc SAND is a polyanionic cellulosic polymer that is used to control the filtration characteristics of drilling fluids.

Application

High-viscosity / low-viscosity polymer is used to control the filtration and rheological properties of water-based drilling fluids, primarily as a thickening agent. Provides additional viscosity and promotes the formation of a strong filter cake, preventing filtration into the rock.

Physical properties

White or yellowish powder.

  • Purity, %: ≥ 90
  • Degree of substitution: ≥ 0,90
  • Humidity, %: ≤ 10
  • pH: 6,0 — 8,5
  • Дapparent viscosity, cPs: ≥ 30
  • The filtration index in sea water, ml: ≤ 20

Chemical properties

Polyanionic cellulose.


Packaging

Rosfloc SAND is supplied in bags with a polymer liner, weight 25 kg.

Safety requirements

According to acute toxicological characteristics, Rosfloc SAND refers to the 4th class of hazard Ц low-hazard chemical substances as per GOST standard 12.1.007-76. It poses no hazard of acute inhalation intoxication. In case of contact it irritates conjunctiva and skin cover. Rosfloc SAND is fire-flame-proof.

Transportation

Rosfloc SAND is transported by all the type transport according to the rules of cargo transportation.
