Properties
Polyanionic cellulose is white or yellowish powder that is ordorless tasteless and non-toxic. It is soluble in water to form thick liquid. It has good heat-stability and high resistance to salt. It is not fermented. Polyanionic cellulose (PAC) is a sodium carboxymethyl cellulose with high uniformity, high degree of substitution and high quality. White or yellowish powder
Characteristics
It has good water-loss controlling ability, especially PAC is highly effective drop filter-loss agent. Even added at low quantity, it can control water loss at very high level, but does not affect slurry’s other characteristics.
It can form figh quality slurry cake which is strong and flexible.
It has good temperature resistance and superior anti-salt character.Under certain saslt density, it can remain good water-loss capability and certain rheology, so the viscosity in salt solution is the same as in water, which is specially suitable for sea misering and deep well.
It effectively controls thr rheology of slurry,with good on-Newtonian fluid performance.
