Product Description
GH-II can stick on the surfaces of cement hydrate to inhibit contacting between cement and water, also stick on the surfaces of crystal nucleons to prevent their enlarging. So it can retard hydrating of cement slurry.
Characteristics
- GH-II consists of various kinds of compounds, such as cellulose derivative and hydroxycarboxylic acid.
- Normal dosage: 0.1%~1.0% (BWOC).
- Suitable temperature:110℃~170℃(BHCT).
- It is used in the medium-deep and deep well. It can prolong the thickening time effectively and increase the pumped time. It can formulate a right angle thickening cement slurry system.
- It can reduce the consistency of cement slurry and improve the rheology.
- Preferred to be mixed without water. Heated by steam if the wet mix is needed.
