Technical specifications of Chrome Free Lignosulfonate

Moisture ≤10%
Water insoluble substance ≤2.5%
PH 2.8~4.5
Total iron 6~8
Usage

The thinner is suitable for use as viscosity reducer in deep Wells. Suitable for vertical Wells and technically complex inclined Wells. It can reduce viscosity and fluid loss simultaneously in water – based drilling fluid. This product is also suitable for offshore drilling and high salt content and saturated salt conditions of drilling.

Features

Excellent diluent performance, reduce mud filtration effect is remarkable, used in fresh water mud dilution performance is better than salt water mud. Can be used with other types of mud treatment agent. This product is non-flammable, explosive, non-toxic, non-corrosive, safe to use, will not cause pollution to the environment.
