Detailed Description
Product Description PAC LV is low-viscosity polyanionic cellulose (PAC) offered by our company, used as a fluid-loss control additive for drilling mud. PAC LV has low molecular weight which is essentially not a viscosifier. Advantages: Effective in controlling fluid loss Resists attack from bacteria, requiring no preservatives or bactericide Environmentally acceptable Depending on water quality, provides viscosity Functions at all ranges of pH levels in both dispersed and non‐dispersed fluids Application Range and Method When use, directly mixed into drilling fluid. Recommend dosage: Add (2 - 5 kg/m³) of PAC LV filtration control agent slowly through the mud hopper.
