3. Features:
1) With excellent thinning performance and filtration control
capacity and
powerful anti-electrolytes capacity, it is suitable to all kinds of
mud
2) Be effective at temperature more than 150 160°C, it can also be
used at the temperature above 200°C, when cooperated with lignite
derivatives and other temperature-resisting chemicals
3) FCLS is a good emulsifier for oil in water mud
4. Applications:
FCLS may be added into drilling fluids either in the form of
solution or powder,
keep pH value between 9.5 - 10.5; as a thinner at 0.5 - 1.0% and as
a fluid loss
control agent at 2.0 - 5.0%.
5. Packing:packing in plastic woven bags, 25kg per bag.
