Product Description
JKN-DP-100L drag reducing agent (dispersing agent) can adjust the electric charge on the surfaces of cement particles to get proper cement rheology. As a result, it can reduce pump pressure, enhance drilling efficiency and used in construction easily.
Characteristics
JKN-DP-100L is modified by methanal and acetone .
The normal dosage is 0.6%-3.0% (BWOC), and it is not confined to this range in some particular case.
Dissolve easily.
Increasing additive dosage, it can adjust the rheology of the cement slurry effectively, and reduce the consistency.
With good high temperature resistance, it can be used within 30℃-150℃ (BHCT).
Consolidate cement stones, enhance its compression strength and control fluid loss.
With certain retarding property.
Good compatibility with other additives.
