Sulfonated lignite is a lignite humic acid derivative obtained from lignite under the condition of the sulfonating at proper temperature. It is brown-black powder, and is a kind of fresh water drilling viscosity depressant and filtration loss control agent, can resist the temperature of 200℃～220℃. It is a kind of cost-effective mud conditioner.
►Use
Sulfonated lignite is mainly used in petroleum, geological exploration drilling. In the drilling mud, it has a significant role in reducing filtrate loss and viscosity. It can be used together with many kinds of drilling fluids directly. Frequently used with Humic acid kalium, SPNH, Sulfonated phenol formaldehyde resin etc. Normal dosage is 2.0-3.0%.
► Storage & Package
Store it in a dry, cool and vent place. 25KG or 50LB net sealed in 4-in-1 compound paper bag with plastic lining. During storage and transport see that the bag is intact. Avoid damp and sun.
