General description
TRSZ-50 adjusts the electrical charge on cement particles to improve slurry rheology, reduce pumping pressure and improve circulation efficiency. It is convenient and quick to use.
Performance characteristics
- TRSZ-50 is a modified polymer consisting of methanol and acetone.
- Dissolves readily.
- Increasing the dosage regulates cement slurry rheology and reduces consistency.
- Consolidates set cement, increases compressive strength and controls fluid loss.
- Has some retarding effect.
- Suitable for wet or dry mixing.
- Compatible with other additives.
