About the fluid loss agent（Part 2）

At present stage, as a high quality of fluid loss agent products must meet the following requirements:
1.Fluid loss: fluid loss control is under 50 ml in freshwater, even under 30 ml, fluid loss control is under 120 ml in saturated salt water, even under 80 ml.
2.The initial consistency: the lower the initial consistency of cement slurry, the easier pumping, but if too low will lead to slurry system settlement, free water increases, so should not be less than 10 BC; Whereas the higher slurry initial consistency, the more stable cement slurry, but can cause pumping difficulties, so generally no more than 25 BC.
3.Curve of thickening: curve of thickening should be normal, there is no bulge/irregularity phenomenon.
4.the high quality fluid loss agent will not decrease the strength of the cement or little effect on strength of cement.
5.Apparent viscosity: the high quality liquid products is with the smaller apparent viscosity, usually in 1000 ~ 6000 cp, should not be more than 20000 cp.
6.Dosage: usually solid fluid loss agent dosage is < 2%, liquid product dosage is < 5%.

Fluid loss agents are manufactured by Kolanky company, the products are suitable for:
1.Wide temperature range
2.High temperature resistance
3.Salt tolerance
4.Less free fluid
5.Good system flow
6.No need to mix with the another disperser
7.Not retarded
8.Fast strength development
9.Strong compatibility with the any of cement slurry system.
It is absolutely meet the high quality fluid loss additives condition, and is your best choice.
