Key points of system use and maintenance:
(1) When the temperature is lower than 110 ℃, it is recommended to use medium temperature retarder with dosage of 0.3-2%; when the temperature is higher than 110 ℃, it is recommended to use high temperature retarder with dosage of 1-4%.
(2) ZOC-G80L and ZOC-G86Lare recommended for seawater cement slurry system with temperature less than 110 ℃, and ZOC-G87L is recommended for seawater cement slurry system with temperature greater than 110 ℃, and fresh water is used for slurry preparation.
In the case of good rheology, dispersant is not suitable.
