DYM1can be absorbed on the surface of the cement slurry hydrate to inhibit contacting with water and chelating with Ca2+ to prevent crystal nucleus from forming early. Therefore ,it can retard thickening time.
Characteristics:
DYM1 consists of sulfonate and organic salts.
Appearance: Light yellow or brown powder
Normal dosage:0.7%-2.0%(BWOC)
Suitable temperature: 110℃~170℃(BHCT)
Reduce consistency of cement slurry and improve the rheology
The thickening time is adjustable
Has no harmful influence on other properties of cement slurry
