Ferrochrome lignosulfonate can be used as an anticoagulant and a filtration agent

Ferrochrome Lignosulphonate FCLS is a specially prepared thinner and fluid loss control agent used in drilling fluids. It has good high temperature tolerance, and electrolyte resisting properties as well as good compatibility.

Ferrochrome lignosulfonate work as deflocculants and a fluid loss control agent for water based mud systems. It has excellent deflocculating properties at elevated temperatures and in the presence of Contaminants and Functions well in Both Salt water and Fresh water Systems effectively.
 

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

Applications
Ferrochrome Lignosulphonate 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%.
